A “Paperless classroom” is what more and more schools are trying to realize. Students don’t do any handwriting in this class. Instead, they use hand-sized or specially-designed computers. The teacher downloads texts from Internet libraries and sends them to every student’s personal computer.
Having computers also means that students can use the Web. They can look up information on any subject they’re studying, from maths to social science.
A high school teacher, Judy Herrel in Florida, US, described how her class used the Web. “Using a book that’s three or four years old is impossible,” she said.
A paperless classroom is a big step towards reducing the waste of paper.
“Think about the money and trees we could save with the computers,” she said.
But, with all this technology, there’s always a risk that the machines will break down. So, in case of a power failure or a technical problem, paper textbooks should still be widely available (可得到的) for these students.
小题1:The underlined word “critical” in the first paragraph probably has the same meaning as _______.
| A．worrying | B．dangerous | C．happy | D．important |
| A．pens | B．computers | C．test papers | D．notebooks |
| A．the Web can talk the students everywhere |
| B．the Web can take the place of teachers |
| C．the Web is a better tool for information |
| D．the Web is for downloading information |
| A．students won’t have trouble with their pens |
| B．computers may break down sometimes |
| C．students may not get all information from the Internet |
| D．paper textbooks may give students more information |
答案
小题1:D
小题2:B
小题3:C
小题4:B
解析
小题1:第一段最后一句为which always seem to run out of ink at the critical moment.所表示的含义为应该为似乎总是在最关键的时候用完了墨水，所以critical单词的意思最接近重要的意思，故本题选D。
小题2:本文第二段第二句为they use hand-sized or specially-designed computers.所表示的含义为在无纸的课堂需要电脑，故本题选B。
小题3:本文第三段第一句为Having computers also means that students can use the Web. They can look up information on any subject they’re studying,所表示的含义为所表示的含义为网页为我们查找有关学习的信息提供了更好的工具，故本题选C。
小题4:本文最后一段提到电脑有时会被摔坏，所以纸课本应该仍然被广泛的使用，故本题选B。

Life today brings new problems. One of the biggest is pollution. Water polluti
on has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and we become angry more easily. Air pollution is t
he most serious kind of pollution to all living things in the world.Cars, planes and factories all pollute our air every day. Sometimes the polluted air is very thick. People cannot see the sky clearly
.Many countries are making rules to fight against pollution. Factories now must clean their water before they throw it away. And they mustn’t let dirty smoke go into the air.
There are many things we can do to fight against pollution. We should put waste things in dustbins and do not throw them on the ground. We should go to work by bike or on foot instead of taking a car or a bus. If there are fewer people driving, there will be less pollution.
Ru
les are not enough. We should do our best to fight against pollution.小题1:Which of the following is NOT true about life in the past?

Oriole’s Nest
Picky, Picky
Scientists have no idea exactly why birds choose certain objects to build their nests. But scientists know that the main reason birds build nests is to keep their babies safe, warm and healthy.
Baby birds grow faster and are healthier when they are warm. They also learn to fly and leave the nests sooner than birds without warm homes.
What A Yarn (纱)
Yarn is big on an oriole’s shopping list during nest building. Scientists are still trying to work out why so many birds choose white yarn over other colors for nest building.
Scientists think that the white objects remind birds of cotton fluff (绒毛) they find in the wild.
Do It Naturally
Even though birds can help us recycle some of our junk by using it to build nests, they also need to use lots of natural things. Long grass, dried sticks, spider’s silk and mud are some of the natural ingredients that are good for nests, too.
You can make a collection box of things to leave for birds so they can help themselves. Hang a small plastic box with holes on a tree branch. Fill the box freely with nest building goodies. Hang the box on a tree and watch birds climb on board to pick through the junk to find their treasures.
Warning: Don’t let the birds turn into a tasty treat. Keep your bird station away from places where cats hang out.
For The Birds!
Stop! Don’t throw all that garbage out! Give some to the birds. Look and see how your old junk can help beautify and warm a bird’s new home.
小题1:The baby birds with warm homes are able to _____.
| A．choose right objects | B．leave the nests sooner |
| C．build good nests | D．learn to fly higher |
| A．Holes on the tree. | B．Food out of the rubbish. |
| C．A warning board. | D．A collection box of things. |
| A．Birds build nests to store things. |
| B．Birds regard white objects as cotton. |
| C．Birds and humans can help each other. |
| D．Birds and cats fight against each other. |
I greatly encourage you to be a part of the school sports. Even if you are not the best, you can still have fun. Sports give people a great and healthy way of spending an afternoon, instead of lying around playing video games or even getting into bad things. Sports also give us a sense of achievement. There isn’t a better feeling than to have done something fun and productive for my day.
I think that we all need sports to give us courage. If we try hard in sports, we usually do well. If we did the same in study, we would all be champions. Another reason why I encourage you to play sports is that it’s just fun. Without sports, our lives would just be boring. So as you may be able to tell, sports are amazing!
Our coaches not only teach us to play sports, but show class and good sportsmanship while playing them. It’s never fun when you lose to have the competitor rub it in your face. That’s why our coaches teach us to show class when we lose; also, when coaches get onto you, don’t get down. They only want to see you improve and learn from what they say. When you do badly and they don’t shout loudly is when you should start worrying because they are giving up on you.
Overall, sports are great! They bring out the best and worst of a lot of us. However, we can’ t let sports get too serious to where it brings down all the fun. So to have the most fun in sports, you just need try your best and not worry so much about the winning or losing.
小题1:The underlined phrase “get onto you” in Paragraph 4 probably means ________.
| A．point out your mistakes | B．take up your time |
| C．worry about your future | D．look into your privacy |
| A．Sports bring us great fun only if we have the talent. |
| B．Sports give us the best way of spending free time. |
| C．We can get more out of winning than losing. |
| D．We should take pleasure in doing sports. |
| A．Are we too caught up? | B．To win or to gain? |
| C．Are sports really great? | D．For honor or for health? |
Daily habits like eating more healthy food would have kept millions of families from becoming bankrupt（***）if the patients had taken ways for early prevention. For example, keeping a balanced diet（均衡饮食）, such as not consuming too much animal fat and trying to have enough vegetables and fruits, seems to be quite important.
One very effective and costless way of prevention is regular（定期的）exercise, which is necessary for a healthy mind and body. Regular exercise, such as running, walking, and playing sports is a good way to make people feel better.
In addition, health education plays a key role in improving people’s health. By giving people more information about health, countries could help people understand the importance of disease prevention and ways to achieve it. For example, knowing one’s family medical history is an effective way to help keep healthy. Information about health problems among close relatives will make them aware of what they should do to prevent certain diseases through lifestyle changes, which will work before it is too late.
However, paying more attention to disease prevention does not mean medical treatment is unimportant. After all, prevention and treatment are just two different means toward the same effect. In conclusion, we could save money on health care and treat patients more successfully if our country spends more money on health prevention and education.
小题1: What’s the meaning of the underlined word “consuming” in Paragraph 2?
| A．Avoiding. | B．Producing. | C．Eating. | D．Cooking. |
| A．Health or Illness? | B．Exercise or Illness? |
| C．Prevention or Education? | D．Prevention or Treatment? |
| A．more health education should be given |
| B．dressing warmly can prevent diseases |
| C．a balanced diet is cheaper than regular exercise |
| D．the government’s health budget should be increased |
It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls may learn to speak earlier, and that women can understand sorts of different information at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.
There are other important differences between two sexes（性别）. As white matter is the key to spatial（空间的）tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries: why men refuse to ask for directions … and women often need to!
The differences begin when fetuses（胎儿）are about nine weeks old, which can be seen in the action of children when they are very young. A boy would try to climb a barrier before him or push it down while a girl would ask for help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors, among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.
小题1:Which of the following is TRUE according to Paragraph 1?
| A．Grey matter controls thinking in the brain. |
| B．Men’s brain is 10% less than women’s. |
| C．Grey matter plays the same role as white matter. |
| D．Men and women have the same amount of white matter. |
| A．Men have weaker spatial abilities. |
| B．Women do not need to tell directions. |
| C．Women prefer doing many things at a time. |
| D．Women do many jobs at a time better than men. |
| A．Our children needed more spatial skills. |
| B．Women may have more feelings than men. |
| C．Young boys may be stronger than young girls. |
| D．More women take up jobs requiring speech skills. |
| A．ways of being more intelligent |
| B．differences between men and women |
| C．studies on brains between two sexes |
| D．studies on white matter and grey matter |
