Hi guys! I’m Lucy the ladybird and while I’m very much of a lady, I’m not actually a bird but a glowing red bettle(甲蟲(chóng))with decorative black spots.
I’m a friendly little bug, to be honest, and simply like to be close with my pals as long as they handle me very gently. I don’t bite humans but I do sink my teeth into aphids (蚜蟲(chóng)) which, unlike me, are very harmful to all the plants. I milk the aphids just like people do with cows and I milk them dry of all the sap (汁) they have got from your poor plants. I’m a real gardeners’ friend and love helping out around the place by pollinating (授粉) flowers, tidying up plants’ fallen leaves and helping to turn them into nice rich fertilizer to feed everything both above and below the soil, and naturally, being so attractive to look at, we are perfect living garden decorations.
One thing I can not tolerate is all that poisonous pollution from vehicles, garbage burning and other environmentally unfriendly acts that occur in the cities every single minute of the day and night. Pollution of any kind really chokes me to death, so these days, I only live in clean countryside areas, particularly cool ones where it rains and everything grows fresh and green from spring right through to autumn. In winter, when the weather is too cold for me to bear, then I find a nice place to sleep until the snow has gone and I can come back out to play.
Oh! I almost forgot to tell you that although I am not a bird I do have wings and can fly for short distances. So if you pick me up and let me run up and down your hands and arms, then please don’t frighten me by screaming if I suddenly decide to take off!
小題1:What makes Lucy the Ladybird suffer most?

With only about 1, 000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species. That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.
Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2, 000 species of mammals, birds, reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal. The entire procedure could take from three to five years to complete.
“The nuclear transfer of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A & M, the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”
小題1: The aim of “Noah’s Ark” project is to _______.
A.make efforts to clone the endangered pandasB.save endangered animals from dying out
C.collect DNA of endangered animals to studyD.transfer the nuclear of one animal to another
小題2: According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.
A.a(chǎn)vailable panda eggsB.host animalsC.qualified researchersD.enough money
小題3:The best title for the passage may be _______.
A.China’s Success in Pandas CloningB.The First Cloned Panda in the World
C.Exploring the Possibility to Clone Pandas D.China —the Native Place of Pandas Forever
小題4:From the passage we know that _______.
A.Kraemer and his team have succeeded in cloning a dog
B.scientists try to implant a panda’s egg into a rabbit
C.Kraemer will work with Chinese scientists in clone researches
D.a(chǎn)bout two thousand of species will probably die out in a century

It is interesting how NASA(美國(guó)航天航空局) chose their astronauts for landing them on the moon. They chose men   36  the ages of twenty and thirty-five. There were about fifty of them. Some were   37  air pilots, and  38  were scientists with two or three degrees. NASA telephoned each man they were going to choose, told him the plans and the   39  they might get into. They then asked him if he was willing to be trained as an astronaut, “How could any man   40  such an exciting job?” One of them said, “Dangerous? Of course. It’s dangerous   41  most exciting.”
The health and physical condition of the people was,  42 , very necessary. Only those in very good health and physical condition were   43 .
While being trained to be astronauts, they went through many   44 . They studied the star and the moon, and they also studied geology, the science of rocks. This was necessary   45  astronauts would have to look for rocks on the moon. They would try to find rocks which might help to tell the   46  of the moon. They were all   47  to fly in helicopters. There helicopters landed straight down to give them some   48  of the way the spaceship would actually land on the   49 . They were also taught the known facts about the   50  in space. They learnt about all the scientists and engineers who   51  spaceships. They visited the   52 where spaceships were repaired. They learnt how every   53  of a spaceship and its instruments work. They also learnt every detail of ground-control   54 .
In a word, to be chosen as astronaut, one must be in good   55 , well-informed in science and good at piloting.

Can you understand the beginning of this essay?
“My smmr hols wr CWOTT. B4, we usd 2go2 NY 2C my bro, his GF & 3 kds FTF.”
The Scottish teacher who received it in class had no idea what the girl who wrote it meant. The essay was written in a form of English used in cell phone text messages. Text messages (also called SMS2) through cell phones became very popular in the late 1990s. At first, mobile phone companies thought that text messaging would be a good way to send messages to customers, but customers quickly began to use the text messaging service to send messages to each other. Teenagers in particular enjoyed using text messaging, and they began to create a new language for messages called texting.
A text message is limited to 160 characters, including letters, spaces, and numbers, so messages must be kept short. In addition, typing on the small keypad of a cell phone is difficult, so it’s common to make words shorter. In texting, a single letter or number can represent a word, like “r” for “are,”“u” for “you,” and “2” for “to.” Several letters can also represent a phrase, like “l(fā)ol” for “l(fā)aughing out loud.” Another characteristic of texting is the leaving out of letters in a word, like spelling “please” as “pls.”
Some parents and teachers worry that texting will make children bad spellers and bad writers. The student who wrote the essay at the top of this page said writing that way was more comfortable for her. (The essay said, “My summer holidays were a complete waste of time. Before, we used to go to New York to see my brother, his girlfriend, and their three kids face to face.”)
Not everyone agrees that texting is a bad thing. Some experts say languages always evolve, and this is just another way for English to change. Other people believe texting will disappear soon. New technology for voice messages may soon make text messages a thing of the past.
小題1:What is the writer’s opinion of text messaging?
A.It is fun and easy to do.
B.It is not bad for children.
C.It will make children bad writers.
D.The writer does not give an opinion.
小題2:Which characteristic of texting is NOT described in the passage?
A.Using phrases to represent essays
B.Using numbers to represent words
C.Using letters to represent phrases
D.Using letters to represent words
小題3:Which of the following was most probably the title of the student’s essay?
A.My Gr8 TchrB.CU in LAC.My GFD.My Smmr Hols
小題4:   Why do some people think that texting is bad?
A.It costs too much.B.It’s too difficult to type.
C.Children won’t learn to write correctly.D.It’s not comfortable.
小題5:Why aren’t some people worried about the effect of texting?
A.Not many people use texting.
B.Spelling in English is too difficult.
C.Children quickly become bored with texting.
D.Texting will disappear because of new technology.

There are hundreds of things that your parents controlled for you when you were a child.And it’s a good thing, too — kids need this kind of protection and assistance, because they aren’t mature enough to take care of themselves and make careful decisions on their own.
But eventually, kids grow up and become teens.It’s totally normal for teens to create their own opinions, thoughts, and values about life; it’s what prepares them for adulthood.But as you change and grow into this new person who makes his or her own decisions, your parents may have a difficult time adjusting themselves to it.
In most families, it’s this adjustment that can cause a lot of fighting between teens and parents.Teens get angry because they feel parents don’t respect them and aren’t giving them space to do what they like, and parents get angry because they aren’t used to not being in control or they disagree with the teens’ decisions.
It’s easy for feelings to get very hurt when there are conflicts like these.And more complicated issues can cause even bigger arguments, because your parents will always be intent on protecting you and keeping you safe, no matter how old you are.
The good news about fighting with your parents is that in many families the arguing will lessen as parents get more comfortable with the idea that their teens have a right to certain opinions.It can take several years for parents and teens to adjust to their new roles, though.In the meantime, concentrate on communicating with your parents as best you can.
Sometimes this can feel impossible — like they just don’t see your point of view and never will.But talking and expressing your opinions can help you gain more respect from your parents, and you may be able to reach a compromise that makes everyone happy.Keep in mind, too, that your parents were teens once and that in most cases, they can relate to what you’re going through.
小題1:Why do parents always want to control their children?
A.They are afraid to lose their children.
B.They want to protect their children.
C.They don’t believe the ability of their children.
D.They can’t accept their children are growing.
小題2:The author suggested that teenagers ________.
A.fight with their parents bravely for their rights
B.obey their parents without any doubt
C.communicate with their parents actively
D.persuade their parents in as many ways as possible
小題3:It can be inferred from the passage that ________.
A.most parents will give in while fighting with their children
B.the conflict between parents and teenagers can be solved
C.the only way for teens to get freedom is to leave home
D.only few parents do well in facing the growth of their children

Global warming is the process of earth’s atmosphere heating up. Over the last 100 years, the average temperature of earth’s atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth’s climate.
Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment which are some of the reasons why the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.
The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, making it hard for heat energy to go into space. In the past, the climate didn’t change much because nature produced just the right amount of greenhouse gases to deal with it.
Today, most scientists are pretty sure that the rising temperature can’t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.
The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.
Over the past 100 years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts.
小題1:What is mainly talked about in this passage?
A.The melting of glaciers.B.Global warming.
C.The world’s weather.D.The earth’s temperature.
小題2:What causes global warming according to scientists?
A.Human activities.B.The nature itself.
C.The earth’s atmosphere.D.New discoveries
小題3:How can greenhouse gases make the globe warm?
A.They keep heat in the atmosphere.
B.They let the heat go out into space.
C.They release heat into the air
D.They can make the other gases warm.
小題4:From the passage we can see that global warming will bring about _____.
A.the pollution in the atmosphereB.natural disasters
C.population pollutionD.the rise of glaciers

As if there weren’t enough of them in the world already, scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned, says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She hopes that the insects , which are very easy to experiment with , will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic (治療的) stem cells.
In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus(細(xì)胞核) has been removed. At the moment, the majority of cloned mice, sheep and other animals die before birth. It is thought this is because the adult DNA is not properly ‘reprogrammed’.
Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals. That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important. If such genes are confirmed, then in theory cloned mammalian embryos(晶胚) might be grown in selected solutions that change the activity of those genes to improve the technique’s success rate. Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful. The team used a slight difference on the standard cloning process: they transferred nuclei taken from embryos rather than fully-grown adult cells. They sucked several nuclei (pl)out of developing fly embryos, and injected them into a fertilized(已受精的) fly egg. From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics.
小題1:The best title of this passage probably is _______.
A.The importance of clone
B.First insects are cloned
C.The disagreement in clone
D.The advantages of clone
小題2:The scientists cloned flies because________.
A.there are fewer and fewer flies in the world
B.flies are easy to find and cheap to use
C.they can gain some experience before cloning other animals
D.it is safe to clone flies
小題3:The failure of most cloned animals is due to _______.
A.the difference of other animals’ genes
B.the improper technique of clone
C.the complex of other animals
D.the improper rearrange of the adult gene
小題4:It can be inferred from the last paragraph that ______.
A.the clone of insects before used grown-up cells
B.the clone of insects were never experimented before
C.this time scientists cloned flies successfully and easily
D.based on this success, other animals will be cloned in large quantities.

There were two interesting pieces of news items in the paper a few years ago. One was about a man who received a bill from the telephone company for $ 2,000 a month for doing nothing.
  The connection between the two news items is simple; computers-the best invention of the 20th century. The telephone bill came from a computer which made a terrifying mistake; that man’s bill was only $ 23.26. The other item was not as amusing. A man walked into the unguarded computer room of a large packaged food company and expertly programmed the computer to pay him $ 2,000 a month for raw meat which he “supplied ” to the company. Of course he never sent the meat, but he certainly received the money . The computer wrote out a bill, and even “signed ” it. It was only a random (隨便) check that uncovered the trick. It could be happening in thousands of other companies all over the world.
  Computers are not the magical workers that some people say they are. They make mistakes, they’re sometimes slower than human beings and they’re easily fooled.
  The US used to conscript (征兵) people with the help of a computer. The army sent out a card, which had to be filled in and sent back. It was easy to avoid being called up simply by spreading candle-wax(臘) on the card. The computer couldn’t read the card, and did nothing with it.
  It’s in our everyday life that computers cause many problems. Let’s get back to using people instead of computers, before a mistake that we can’t put right.
小題1:In the first paragraph we can conclude ______.
A.the paper is telling a lieB.the first sentence is the topic sentence
C.the two news items made people surprised
D.if a man did nothing at all for the telephone company, he would still get $2,000 a month
小題2:The main idea of the second paragraph is _______.
A.the computers are magical workers
B.the computers can do anything as well as man
C.the computers can write out the bill and even sign it
D.the computers sometimes also make mistakes
小題3:Computers ______.
A.were used to conscript peopleB.a(chǎn)re usually faster than human beings
C.a(chǎn)re not so magical as people expect
D.were not easily controlled and always fooled human beings
小題4:The writer thinks _______.
A.we’d better use people instead of computers in our everyday life
B.we should not use computers because they always make mistakes
C.computers are widely used in our everyday life
D.if we want to work well, don’t use the computers
