Tiredness, coughing, a runny nose and a sore throat—among all sicknesses there is probably none more common than the flu, which we all get now and then.
However, bird flu is a completely different story.
Ten years ago, the H5N1 bird flu swept across 15 countries, including China, with sufferers reporting chest pain, difficulty breathing, fever and severe coughing. More than 600 people were infected, and about 60 percent died. Now another type of bird flu hit Shanghai and three neighboring provinces, and this time the virus is called H7N9. By the afternoon of April 11, the new virus had taken nine lives out of 35 infected, according to Xinhua News Agency.
The“H”and“N”in the virus’ name refers to two kinds of proteins on the surface of the virus. Any change of the numbers of the two proteins indicates a new mutation(變異). Most of the mutations only affect birds, such as chickens and pigeons, and don’t normally spread to humans. But once they do, the results can be disastrous.
“Any time an animal influenza virus crosses to humans, it is a cause for concern, ”Malik Peiris, virologist(病毒學家)at the University of Hong Kong, told Nature magazine. Take the SARS epidemic(傳染病)10 years ago as an example. The virus behind the disease is thought to have jumped to humans from animals. The virus was a complete“stranger”to human bodies, which hadn’t developed an immunity against it.
But there is something more about the new H7N9 bird flu. Unlike the H5N1 bird flu, which causes severe sickness in birds, the H7N9 has been evolving under the radar(悄悄地)since it travels between birds without causing noticeable illness. That makes it difficult to keep track of the disease.
The good news is that there’s so far no sign that the virus is spreading from person to person. But since there is no vaccine for the disease yet, the World Health Organization recommends that you wash your hands after meeting with sick people and before and after you eat or prepare food, and they also suggest avoiding contact with birds or their eggs.

For most people, shopping is still a matter of wandering down the street or loading a cart in a shopping mall. Soon, that will change. Electronic commerce (trade) is growing fast and will soon bring people more choices. There will, however, be a cost: protecting the consumer from being cheated will be harder. Many governments therefore want to apply street regulations to the electronic world. But politicians would be wiser to see cyberspace as a basis for a new era of corporate self-regulation.
Consumers in rich countries have grown used to the idea that the government takes responsibility for everything from the stability of the banks to the safety of the drugs or their rights to refund when goods are faulty. But governments cannot enforce national laws on businesses whose only presence is on the screen. Even in a country where a clear right to compensation exists, the on-line customer in Tokyo, say, can hardly go to New York to get a refund (退款) for a clothes purchase.
One answer is for government to cooperate more: to recognize each other’s rules. But that requires years of work and volumes of detailed rules. And plenty of countries have rules too fanciful for sober countries to accept. There is, however, another choice. Let the electronic businesses do the regulation themselves. They do, after all, have a self-interest in doing so.
In electronic commerce, a reputation for honest dealing will be a valuable competitive asset. Governments, too, may compete to be trusted. For instance, customers ordering medicines on- line may prefer to buy from the United States because they trust the rigorous screening of the Food and Drug Administration; or they may decide that the FDA’s rules are too strict, and buy from Switzerland instead.
Customers will still need to use their judgment, but precisely because the technology is new, electronic shoppers are likely for a while to be a lot more cautious than customers of the normal sort. And the new technology will also make it easier for them to complain when a company lets them down. In this way, at least, the advent(出現(xiàn)) of cyberspace may argue for fewer consumer protection laws, not more.
【小題1】In case an electronic shopper bought faulty goods from a foreign country, what could he do?
A.Refuse to pay for the purchase. | B.Go to the seller and ask for a refund. |
C.Appeal to consumer protection law. | D.Complain about it on the Internet. |
A.international cooperation would be much more frequent |
B.consumers could easily seek government protection |
C.a(chǎn) good reputation is a great advantage in competition |
D.it would be easy for consumers to complain |
A.very quick | B.very cautious | C.very slow | D.rather careless |
A.Self-regulation by the business. | B.Strict Consumer protection laws. |
C.Close international cooperation. | D.Government protection. |

1. Mean old ladies
There is always a reason why an old lady gives you a serious look – you are being too loud, dressed improperly or not crossing the street in the right place. Sometimes it can be lovely, but if you are already having a bad day, a mean old lady can drive you mad.
What to do about it:
I’ve come to realize that when people start conflicts, it is actually an expression of their inner state expressed in an outside way. You, your personality, your looks or your actions have nothing to do with it. It is not personal, so why take it personally?
2. That person, who cuts in front of everybody in line
This is something that gets me angry. Even if I am not in a hurry, I still feel bad for the other people in line who are being treated unjustly. Are you more patient than I am or do you feel annoying too?
What to do about it:
If we have negative thoughts then we are wasting our energy on negativity. Situations like this could be a great opportunity to learn to control our first negative responses and practice understanding. After all, the person may just have a quick question or maybe there is an emergency.
Friends that tell you “I told you so”
It is one thing to admit that you made a mistake and another to hear it from a friend. Friends should be there to support you and cheer you up when you are feeling down, not make themselves feel better at your expense, right?
What to do about it:
It helps to remember that when people say “I told you so”, they may mean, “Please listen to my advice to avoid future mistakes.” If this is not the help you need – voice it out, without getting defensive.
【小題1】According to the author, what can you do when meeting with a mean old lady?
A.Take it personally. | B.Take it seriously. |
C.Don’t apologize to her. | D.Don’t get upset. |
A.stop him immediately | B.treat it with a good state of mind |
C.pretend not to see it | D.teach him a good lesson |
A.not to keep silent at a friend’s improper suggestion |
B.to tell your friend if they have misunderstood you |
C.not to talk to your friend if they feel better at your expense |
D.to apologize to your friend when you’ve done something wrong |
A.What to do when meeting with these people? |
B.How to ask your friends for help when in trouble? |
C.How to give advice to your friends when asked to? |
D.What to say when faced with different situations? |

You may think that sailing is a difficult sport, but it is really not hard to learn it.You do not need to be strong.But you need to be quick.And you need to understand a few basic rules about the wind.
First, you must ask yourself, “Where is the wind coming from? Is it coming from ahead or behind or from the side?” You must think about this all the time on the boat.The wind direction tells you what to do with the sail.
Let's start with the wind blowing from behind.This means the wind and the boat are going in the same direction.Then you must always keep the sail outside the boat.It should be at a 90° angle (角度) to the boat.Then it will catch the wind best.
If the wind is blowing from the side, it is blowing across the boat.In this case, you must keep the sail half way outside the boat.It should be at a 45° angle to the boat.It needs to be out far enough to catch the wind, but it shouldn't flap (擺動).It shouldn't look like a flag on a flagpole.If it is flapping, it is probably out too far, and the boat will slow down.
Sailing against the wind is not possible.If you try, the sail will flap and the boat will stop.You may want to go in that direction.It is possible, but you can't go in a straight line.You must go first in one direction and then in another.This is called tacking.When you are tacking, you must always keep the sail inside the boat.
【小題1】What should you consider first while sailing?
A.Sailors' strength. | B.Wave levels. |
C.Size of sails. | D.Wind directions. |
A.The boat. | B.The sail. |
C.The wind. | D.The angle. |
A.Move in a straight line. | B.Allow the sail to flap. |
C.Lower the sail. | D.Tack the boat. |
A.In a popular magazine. | B.In a tourist guidebook. |
C.In a physics textbook. | D.In an official report. |

Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there’s no need for a lot of scientific terms or expensive lab equipment. You only have to share your children’s curiosity. Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we’re finished with your lists, do you have questions of your own about science?”
After a long pause, a boy raised his hand, “Have you ever seen a grasshopper(蚱蜢) eat? When I try eating leaves like that, I get a stomachache. Why?”
This began a set of questions that lasted nearly two hours.
Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical, complete and creative answers.
Thirdly, watch your language. Once you have a child involved in a science discussion, don’t jump in with “That’s right” or “Very good”. These words work well when it comes to encouraging good behavior. But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying “That’s interesting” or “I’d never thought of it that way before”, or coming up with more questions or ideas.
Never push a child to “Think”. It doesn’t make sense, children are always thinking, without your telling them to. What’s more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target(目標) for your disagreement.
Lastly, show; don’t tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass(放大鏡), and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates(蒸發(fā)), set a pot of water to boil and let them watch the water level drop.
【小題1】According to the passage, children are natural scientists, and to raise their interest, the most important thing for adults to do is _______.
A.to let them see the world around |
B.to share the children’s curiosity |
C.to explain difficult phrases about science |
D.to supply the children with lab equipment |
A.a(chǎn)ny questions | B.a(chǎn)ny problems |
C.questions from textbooks | D.a(chǎn)ny number of questions |
A.a(chǎn)sk them to answer quickly |
B.wait for one or two seconds after a question |
C.tell them to answer the next day |
D.wait at least for three seconds after a question |
A.The second and third. | B.The fourth and fifth. |
C.The fifth and sixth. | D.The fifth. |
A.tell their children stories instead of reciting(背誦) facts. |
B.offer their children chances to see things for themselves. |
C.be patient enough when their children answer questions. |
D.encourage their children to ask questions of their own. |

The Great Barn Adventure
One morning when I was 11, I explored the town’s abandoned round grain barn(谷倉). I found a chained sliding door that was wide enough for me to pass through.
Inside, there was a heavy smell of dead mice in the dark. After my eyes adjusted, I noticed a shaft (升降機井) that rose all the way to the top of the barn. On one side was a one-man elevator with a long rope and roller.
I stepped onto the platform and gave the rope a drag and the elevator began sliding up the shaft, but stopped halfway. After a brief panic attack, I noticed holes in the wall at regular intervals, forming a ladder. For reasons known only to an 11-year-old, I decided it would be better to go up than down. So, with shaking hands, I began climbing the wall.
After what seemed like forever, I reached the top of the shaft. I stood up, dusted myself off and found absolutely nothing of interest. It was just an empty room with a ladder leading up to the roof. I climbed all the way up here for this? Then I noticed a fire extinguisher(滅火器),which I’d always wanted to shoot off. So this was the chance of a lifetime. I tried it, and, much to my surprise, the thing worked! It shot out a thick cloud of powder that instantly filled the room. I couldn’t breathe. I was going to choke to death, and they’d probably never even find my body.
Luckily, I remembered the ladder to the roof. I climbed up, popped the straw roof and saw a bright blue sky.
I suddenly realized the dust and powder pouring out of the top could draw attention. So when the dust had settled, I climbed down and slipped out of the chained door. I’m not sure if I was more excited about being alive or about not being caught, but I ran all the way back home.
【小題1】When the author got inside the barn, he _______.
A.noticed a man on the elevator |
B.opened the chained sliding door |
C.saw many dead mice in the dark |
D.found a shaft leading to the top |

閱讀下面短文,從各題所給的A、B、C、D四個選項中選出最佳答案。
As summer comes near, many children are really happy to forget about school for a few months. However, they might be taking that goal too seriously. Studies have found that children often forget between one and three months’ worth of school learning during the summer months. Spelling and math abilities drop off the most, while reading is not really influenced by the time off. The main reason for this is because most children sometimes read outside of the classroom, whether newspapers, magazines, books, or video game guides. However, their math and spelling skills only get exercised in the school setting.
The first purpose of summer holidays was to let farm children have time off to help work in the fields during the growing season, but this reason is no longer a good one since fewer kids actually work on farms today. Some cities in the United States, such as Los Angeles, have moved to a year-round school timetable, which may help reduce the loss of school skills that happens during the long summer holiday. To improve skills and to keep a good level of preparation, headmasters suggest trips to museums, summer camps, holidays with educational value, and visits to libraries to keep kids interested throughout the summer.
There are other educational systems that provide holidays while still keeping students’ skills up to date. For example, in Japan, students attend class for seven weeks in a row, followed by two weeks of holiday. This continues the whole year. In Italy, students attend class six days per week, but finish at 1: 30 pm each day, so that school does not run their life the way that it does in America, where students attend high school from 7: 45 am until 3: 00 pm each weekday. In areas where there are not enough classrooms—in Afghanistan or Somalia, for example—older students attend classes in the morning while the younger kids go to school in the afternoon.
Headmasters fear that the three-month summer holiday stops the flow of learning. Just as students become used to new math problems or new ideas in reading, writing, or thinking skills, they “shut down” during the summer holiday. When they go back to school after the long summer holiday, they take up to two months to return to their previous (先前的) level of skill. So the debate continues: whether to continue holidays or to make changes based on the Los Angeles or the Japanese models.
【小題1】Which skills suffer the most over the summer holidays?
A.Math and reading. | B.Math and spelling. |
C.Reading and writing. | D.Reading and thinking. |
A.It is still widely acceptable now. | B.It was popular in some cities. |
C.It is not a good reason for city kids. | D.It was more for teachers than for students. |
A.stop learning | B.get sick |
C.go on reading | D.focus on studies |
A.Parents always read to their kids to keep reading skills. |
B.Summer holidays lead to the loss of all the school skills. |
C.Students love holidays and get their mind off learning in holidays. |
D.In Italy students attend classes in the late afternoon six days a week. |
