The Internet is not perfect. There are many problems with it.
The Internet is not organized. There is no one in charge of the Internet. It is sometimes difficult to find what you are looking for. It is also easy to get the wrong information on the “Net”.
Some businessmen cheat people on the Internet. Internet thieves can steal credit card numbers. Some advertisers send spam to e-mail boxes. E-mail boxes are often filled with these unwanted advertisements.
Illegal businesses can operate on the Internet. These businesses sell X-rated materials, cigarettes and alcohol to teenagers.
The Internet has websites with information about making bombs, breaking the law and terrorism.
Criminals can fool people, especially children, in chat rooms. They can spread poisonous information and attack new members.
The Internet is the greatest advance in communication since human emerged. But it can also like a dark alley in a dangerous part of town. Parents need to set parental controls on their children when they use the Internet. This will keep some of the bad material away from their children.
The Internet can be dangerous to computers, too. Some people who have evil intentions enjoy causing problems for other people they don’t even know. They create computer viruses. A computer can get virus by downloading a program that has a virus in it. Some virus come by e-mail.
A virus can destroy the data a person has saved in computer files. A virus can cause a computer to crash. A virus can also reproduce itself! It can send copies of itself to everyone on a person’s e-mail address list. Then these people’s will have the same problems and can’t work normally!
小題1:Why can illegal businesses operate on the Internet?
A.Because some people like to buy banned products on the Internet.
B.Because there is no one in charge of the Internet.
C.Because X-rated materials, cigarettes, alcohol and so on can be sold well on the Internet.

These days we are all conditioned to accept newness, whatever it costs. Very soon, there is no doubt that Apple's tablet (平板電腦) will seem as a vital tool of modern living to us as sewing machine did to our grandparents. At least, it will until someone produces an even smarter, thinner and more essential tablet, which, if recent history is any guide, will be in approximately six months' time. Turn your back for a moment and you find that every electronic item in your possession is as old as a tombstone. Why should you care if people laugh just because you use an old mobile phone? But try getting the thing repaired when it goes wrong. It's like walking into a pub and asking for an orange juice. You will be made to feel like some sort of time-traveler from the 1970s. "Why not buy a new one?" you will get asked.
And so the mountain of electrical rubbish grows. An average British person was believed to get rid of quite a number of electronic goods in a lifetime. They weighed three tons, stood 7 feet high, and included five fridges, six microwaves, seven PCs, six TVs, 12 kettles, 35 mobile phones and so on. Even then, the calculation seemed to be conservative. Only 35 mobiles in a lifetime? The huge number of electronic items now regularly thrown away by British families is clearly one big problem. But this has other consequences. It contributes greatly to the uneasy feeling that modem technology is going by faster than we can keep up. By the time I've learnt how to use a tool it's already broken or lost. I've lost count of the number of TV remote-controls that I've bought, mislaid and replaced without working out what most of the buttons did.
And the technology changes so unbelievably fast. It was less than years ago that I spotted an energetic businessman friend pulling what seemed to be either a large container or a small nuclear bomb on wheels through a railway station. I asked. "What have you got in there? Your money or your wife?" "Neither," he replied, with the satisfied look of a man who knew he was keeping pace with the latest technology, no matter how ridiculous he looked. "This is what everyone will have soon—even you. It's called a mobile telephone."
I don't feel sorry for the pace of change. On the contrary, I'm amazed by those high-tech designers who can somehow fit a camera, music-player, computer and phone into a plastic box no bigger than a packet of cigarette. If those geniuses could also find a way to keep the underground trains running on the first snowy day of winter, they would be making real progress for human beings. What I do regret, however, is that so many household items fall behind so soon. My parents bought a wooden wireless radio in 1947, the year they were married. In 1973, the year I went to university, it was still working. It sat in the kitchen like an old friend—which, in a way, it was. It certainly spoke to us more than we spoke to each other on some mornings. When my mum replaced it with a new-style radio that could also play cassette-tapes, I felt a real sense of loss.
Such is the over-excited change of 21st-century technology that there's no time to satisfy our emotional needs. Even if Apple's new products turn out to be the most significant tablets I very much doubt if they will resist this trend.
小題1:When you try getting an old mobile phone repaired, ____.
A.you are travelling through timeB.you are thought to be out of date
C.you will find everything wrongD.you have got to buy a new one
小題2:Throwing away so much electronic rubbish makes the writer feel quite _____.

小題3:The example of the businessman implies that____.
A.the businessman mastered the latest technology
B.mobile phones used to be quite big just years ago
C.the businessman was a very ridiculous person
D.the writer failed to follow modern technology

A.The fast pace of change brings us no good.
B.We have to keep up with new technology.
C.Household items should be upgraded quickly.
D.We should hold on for new technology to last.

As computers become more popular in China, Chinese people are increasingly relying on computer keyboards to input Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes(筆畫(huà))of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.
Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more wide-spread among university students. Almost all their assignments and essays are typed on a computer.
All the students interviewed say they usually use a computer.
It's faster and easier to correct if using a computer. And that's why computers are being applied more and more often to modern education. But when people are taking stock in computers increasingly, problems appear.
“When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I’m familiar with it.”
“I'm not in the mood to write when faced with a pen and paper.”
Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?
Many educators think differently. Shi Liwei, the headmaster of a famous primary school in the capital said, “Chinese characters enjoy both practical and aesthetic (審美的) value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them.”
To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory (必修的) and in universities, some professors are asking students to turn in their homework and essays written by hand.
小題1:Which of the following can best serve as the title of the passage?
A.The Importance of Handwriting and Typing
B.To Type or To Hand Write
C.Writing By Computer Will Replace Writing By Hand
D.Practical and Aesthetic Value of Chinese Characters
小題2:The students interviewed prefer to write using a computer mainly because ______.
A.they are usually asked to e-mail their Homework and Essays
B.they can correct the mistakes they make quickly and conveniently
C.they find it not easy to remember how to write a character
D.computers have become a trend and fashion in China
小題3:Which of the following statements is NOT TRUE of the advantages of handwriting?
A.Handwriting contains the writer's emotion.
B.The writer’s thinking and personality are shown in his or her handwriting.
C.Handwriting can impress people well and build one’s self-confidence.
D.Chinese characters enjoy both practical and aesthetic value.
小題4:The underlined expression “taking stock in” (Paragraph 4) probably means _____.
A.getting bored withB.getting dependent on
C.becoming crazy aboutD.getting curious about
小題5:We can draw the conclusion from the passage that _______.
A.more and more students will give up writing on a computer
B.writing by hand will give way to typing by computer one day
C.more and more students will pay attention to handwriting
D.the typing article better expresses one’s emotion and quality

Not everyone goes to university after high school graduation. Some work, others join the army and an increasing number worldwide are taking a “gap year” to travel or do community service in their own countries or abroad. They are studying sharks off the Australian coast, building schools in Mexico and learning Spanish or Italian.
The concept of a gap year may not be new, but the recent surge (涌現(xiàn)) of interest certainly is.  Some students are putting off admissions. Others, who don’t get into the college of their choice, are taking a year to explore new frontiers before reapplying.
Students are choosing to take a breather; they are thinking. They are not sure what they are going to do. They are going and exploring some of their interests. They are getting experience they can take to the school they finally go to.
It is an idea actively encouraged by colleges. Princeton University has just launched a “bridge year” program that will send 10 percent of its incoming class to do volunteer work abroad, starting in 2009. And the Harvard has spent the last 30 years urging incoming students to take a gap year.
“Many speak of their year away as a ‘life-changing’ experience or a ‘turning point’” says Harvard admissions director Marlin Lewis. “Many come to college with new opinions about their academic plans, their extracurricular interests and the career possibilities they observed in their year away.”
小題1:The reasons why some take a gap year are the following EXCEPT that ________.
A.they hate studying
B.they don’t know what to do
C.they want to get experience
D.they want to know their real interests
小題2:A student won’t ________ in a gap year.
A.travelB.join the army
C.do community serviceD.learn a foreign language
小題3:After a gap year, one would probably _________.

A.more and more students will take a gap year
B.fewer and fewer colleges will encourage his students to take a gap year
C.the gap year can only give one some experience about society
D.nobody will change his own interests after the gap year

I really hadn’t meant to yell at them. But that grey afternoon saw it just as my son and daughter were making a terrible mess on the floor in the kitchen.
With a tiresome report to write, I felt bothered at my desk. Suddenly, it occurred to me that my kids were at fault. A voice inside me insisted that I do something quickly.
“Ok, you two here, but what an awful thing you are attempting!” I was shouting angrily. I made for them, while it became evident that the boy wanted no part of me. “Get away from us!” he shouted back, there being an expression of support from his sister.
All of a sudden, I found the fault in myself. Quickly I shaped my hands into pincers and crawled towards them, “Crabby Daddy is here. Ha, Ha, Ha, he likes to yell at children, and then eat them!” My son continued to keep me away, but now he was laughing and crying at the same time. My mission to repair the damage caused by my yelling seemed to work well. Still, I regretted not having controlled myself first in a right way.
Need I let them know how badly they were acting by blaming? This is a lesson that serves myself. It only shows just how to get rid of something (ill-feelings, responsibility…) by blaming others. It’s not my “best self”.
We have to search for our “best self” when with our children. They don’t need perfect parents, but they do need parents who are always trying to get better. Here, I am reminded of the words of a great thinker. “When a man lives with God, his voice shall be as sweet as the murmur of the book…” Then, in our lifetime, couldn’t we always speak to our kids in such a sweet voice since most of us consider them as the most precious in the world? And before we reach this level, what should we do when we come across various difficult cases with our children?
小題1:The author couldn’t help yelling at his kids this time probably because________.
A.the weather was so unpleasantB.he was tired of his boring work
C.the kids didn’t ask him to join themD.a(chǎn) Daddy has his right to do so
小題2:Which of the following made the author aware of his fault?
A.No obvious reason.
B.The boy’s yelling back.
C.His self-awareness.
D.The girl’s shouting back.
小題3:According to the passage, the author will _____ in another similar situation.
A.play a crab again like this time
B.a(chǎn)pologize to kids in a sincere way
C.a(chǎn)void blaming kids in a hurry
D.beat them up about such things
小題4:What will the writer go on to write about in the next paragraph(s)?
A.How to behave ourselves properly when kids are at fault.
B.How to play with our children in a more interesting way.
C.How to deal with the housework with children around us.
D.How to persuade children to do what they are told to.
小題5:What does “the boy wanted no part of me” in the third paragraph mean?
A.The boy was happy because I loved them.
B.The boy was curious because I wanted to help them.
C.The boy was very happy for I was angry.
D.The boy didn’t want me to join them.

If you are looking for an animal to take the title of “most violent fish in the sea”, then the tiger puffer (河豚) fish would have to be a strong contestant. Not only is it deadly poisonous --- though that doesn’t stop people trying to eat it --- but it is also able to scare off enemies by inflating itself to become much larger than normal, when it is young it even chews on its own brothers and sisters.
Tiger puffer fish attach their eggs to rocks near the bottom of the sea, often at the mouths of bays. Then the larvae (幼魚(yú)) move to the entries of rivers and lakes once they have grown a little. Then, having put on a lot of weight, they head out to sea. There’s no innocent childhood for the puffer fish, as Shin Oikawa of Kyushu University in Japan and his colleagues found out when they put the larvae of tiger puffer fish in the lab and monitored them for two months. They found that the larvae went through three steps in which their metabolic(新陳代謝) rates increased dramatically when they reached body weights of 0.002g, 0.01g, and 0.1g. When a larva went through one of these steps, its behavior also changed. For instance, once a larva had passed the first level it would have grown its first tooth and could start attacking larvae that had not yet reached that stage. Similarly, any larva that had reached the 0.01g or 0.1g levels would start attacking lighter larvae.
The researchers noted that the baby fish had a “relatively small mouth”, so rather than swallowing their brothers and sisters whole, they would bite pieces out of them. Despite this limitation, the fish caused plenty of deaths --- up to 12 per cent of the deaths that happened in the lab each day.
Those fish that grew fast enough to be able to chew on their fellows had an advantage. The extra food accelerated their growth and development. Tiger puffer fish are likely to be faster and swifter, so they can deal better with enemies.
As the name suggests, puffer fish can inflate to make themselves seem much larger than they really are, thus scaring off enemies. They do this by filling their stomachs, which are extremely elastic(彈性的), with water. If that’s not enough of a threat, the tiger puffer fish --- like most of the other puffer fish in the family --- carries a deadly toxin(毒素). Eat one puffer fish and the poison will paralyze (癱瘓) your muscles, including the muscles responsible for breathing, so death is usually caused by a lack of oxygen. Famously, the fish is a delicacy in Japan, where highly qualified chefs produce dishes that contain the safe level of the poison. Interestingly, the puffer fish does not go to the trouble of producing the poison itself. Instead, it hosts bacteria (細(xì)菌) that produce the stuff. It obtains these bacteria from its diet, so the youngest adult fish are not poisonous.
小題1:All of the following statements account for the violence of puffer fish except that_____.
A.they are very difficult to catch
B.they can become larger to threaten enemies away
C.they kill their younger companions as they grow up
D.they are deadly poisonous
小題2:We can learn from the second paragraph that puffer fish _____.
A.can only grow to a weight of 0.1g
B.do not change their behavior as they grow up
C.like to find a safe place to hatch the next generation
D.begin to grow teeth when they reach the third level
小題3:Where does the poison in the puffer fish’s body come from?
A.Its inner organs.B.The air it breathes in.
C.The diet it eats.D.The bacteria around it.
小題4:Which of the following statements is TRUE according to the passage?
A.Puffer fish can only produce poison when they face danger.
B.People like eating puffer fish even though they are poisonous.
C.The larvae are more aggressive than adult puffer fish.
D.Young puffer fish taste better than adult puffer fish.

The common cold is the world’s most widespread illness, which is plagues(疫病) that people receive.
The most widespread fallacy(謬誤) of all is that colds are caused by cold. They are not. They are caused by viruses(病毒) passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.
During the First World War soldiers who spent long periods in the trenches(戰(zhàn)壕), cold and wet, showed no increased tendency to catch colds. In the Second World War prisoners at the Auschwitz Concentration Camp(奧斯維辛集中營(yíng)), naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet(濕透)in drafty(通風(fēng)的)room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other time, and this makes it easier for cold viruses to be passed on.
No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is relieve the symptoms.
小題1:The writer offered _______ examples to support his argument.
A.4B.5C.6D.3
小題2:Arctic explorers may catch colds when _______.
A.they are working in the isolated arctic regions
B.they are writing reports in terribly cold weather
C.they are free from work in the isolated arctic regions
D.they are coming into touch again with the outside world
小題3:Volunteers taking part in the experiments in the Common Cold Research Unit probably _______.
A.suffered a lotB.never caught colds
C.often caught coldsD.became very strong
小題4:The passage mainly discusses _______.
A.the experiments on the common cold
B.the fallacy about the common cold
C.the reason and the way people catch colds
D.the continued spread of common colds

In 1953, the New Zealander Edmund Hillary, then 33, joined a British Qomolangma expedition led by Colonel John Hunt. Tom Bourdillon and Charles Evans were the first team to attempt the summit (頂峰). Despite a violent storm, they reached the South Summit — at 28,700 feet (8,748 meters) — by 1 p.m. on May 26. But both men knew they would run out of oxygen if they went on. They agreed to turn back.
Two days later, Hillary and Norgay, set out from Camp IX at 25,900 feet to make the next attempt. At 27,900 feet they made a temporary camp on a six foot wide rock to spend the night. At 6:30 the next morning, cheered by clearing skies, the team moved out. Roped together, cutting steps with their ice axes, they inched up a steep, knife-edged ridge (山脊) southeast of the summit. They reached the South Summit by 9:00 a.m.
Farther up, they met a 40-foot icy rock face, which was later named the Hillary Step. “…looking up at the rock step at 29,000 feet, it really did look extremely difficult to overcome,” said Hillary. But they found a narrow crack on the surface of the rock, just large enough to move inside on hands and knees, and managed to climb it by supporting feet against one side and backs against the other. Hillary said, “That was really the first moment during the whole of the expedition that I was confident that we were going to get to the top.” 
The last few yards to the summit were relatively easy. “Then I realized that the ridge, instead of rising ahead, now dropped sharply away,” Hillary said. “I looked upward to see a narrow ridge running up to a sharp point. …and we stood on the summit.” It was 11:30 a.m. on May 29, 1953.
小題1:What is the passage mainly about? 
A.The climbing history of Qomolangma.
B.The life and achievements of Edmund Hillary.
C.How Hillary and Norgay conquered Qomolangma.
D.How the Hillary Step got its name.
小題2:At what height did Hillary and Norgay set out on May 29? 
A.25,900 feet. B.27,900 feet.
C.28,700 feet. D.29,000 feet.
小題3:According to Paragraph 2, one of the main advantages to Hillary and Norgay was        .
A.fine weather conditionsB.good rest the night before
C.enough food suppliesD.good climbing skills
小題4:When looking back, Hillary described the Hillary Step as        .
A.much easier to climb than she expected

Throughout history, people have been interested in knowing how language first began, but no one knows exactly where or how this happened. However, we do know a lot about languages, the languages of today and also the languages of earlier times. There are probably about three thousand languages in the world today. Chinese is the language with the most speakers. English, Russian and Spanish are also spoken by many millions of people. On the other hand, some languages in the world have less than one hundred speakers.
There are several important families of languages in the world. For example, most of the languages of Europe are in one large family called Indo-European. The original (最初的) language of this family was spoken about 4,500 years ago. Many of the present day languages of Europe and India are modern forms of the language of 4,500 years ago.
Languages are always changing. The English of today is very different from the English of 500 years ago. In time some even die out completely. About 1,000 years ago English was a little -known relative of German spoken on one of the borders(邊界)of Europe.
If a language has a lot of speakers or if it is very old, there may be differences in the way it is spoken in different areas. That is, the language may have several dialects. Chinese is a good example of dialect differences. Chinese has been spoken for thousands of years by many millions of speakers. The differences between the dialects of Chinese are so great that speakers of Chinese from some parts of China cannot understand speakers from other parts.
小題1:The first paragraph mainly tells us that_______.
A.most people in the world speak Chinese
B.there are thousands of languages in the world today
C.man has much knowledge about languages
D.some people know several languages
小題2:Many European and Indian languages ______.
