We need to make better use of our resources. In developing countries we have more than enough, if we are less wasteful in our ways. Fortunately, we can improve. The challenge lies not so much with ‘technical fixes’ but with our approach to our world around us. In the recent past we were in a “Wild West” economy, supposing that there would always be enough resources. Now we know there are no new Earth to explore and exploit; one image to illustrate this is to think of Earth as a spaceship, where most materials have to be recycled. For us, “moving on” will be a case of leaving behind the throwaway society and advancing to a conserver society.
To qualify as citizens of a conserver society, we must change traditional attitudes and thinking. We need to recognize that there is not very often such a thing as “waste”, rather, there are materials which sometimes end up in the wrong place. The change has already begun. The European steel industry reuses scrap(废弃的)metal, resulting in an energy saving of up to 50% . Recycling a glass container saves only 18%; but, in parts of the United States, a citizen buying a bottle of soda or beer now pays a deposit against return of the empty bottle.
If all drink containers in the USA were to be reused, the annual saving would be 0.5 million tons glass, plus about 50 million barrels of oil used in production processes. In Japan, OPEC promoted an increase in recycling of raw materials from 16% to 48% in just five years. In Norway, the price of a new car includes a disposal cost element of about 100 dollars, redeemable(可换成现款的)when the junked car is turned in at an approved receiving center.
Major new businesses are trying to exploit waste chemicals and oil. The Chinese claim to reuse 2.5 million tons of scrap iron and at least one million tons of waste paper each year. In the main, the conserver society depends on the commitment of individuals. But they can be encouraged by government incentive(鼓励) and punishment, which should apply at least as strongly to industry and other commercial interests.
73 Which of the following best expresses the meaning of “a conserver society” in the second paragraph?
A. A wasteful society.
B. A society which thinks of ways of recycling waste materials.
C. A society which keeps everything.
D. A society which saves electricity.
74 In the last paragraph, the author suggests governments _______.
A. depends on individuals to find ways of conserving energy.
B. find ways of encouraging those industries and individuals who conserve energy and of punishing those who don’t.
C. depend on companies to find ways of saving energy and rewarding workers
D. help establish businesses that will exploit waste materials
75 In this passage the author _______.
A. explains that meaning of the “Wild West” economy
B. tells us what recycled materials are.
C. teaches us how to recycle materials.
D. recommend a change in our use of resources strongly

Our need to communicate with each other has been a driving force in the development of technology. In the 20th century we have seen the invention of the radio, television, telephone and fax, and today the Internet has opened up a whole new way of communicating. We now have instant messaging services such as ICQ or China's QQ and chat rooms where people can join group discussions. They mean increasing choices for when, where and how to communicate, and more importantly, with whom.
While most people use the Internet to keep in touch with friends and family, a growing number of people use QQ and chat rooms to meet and chat with strangers. Because the Internet allows a certain amount of anonymity, users can be more open making it easier to make new friends. One user said that everyone is equal online, and age and appearance become unimportant. This makes it easier for people to communicate with each other.
Finding new friends is not the only reason people use chat rooms. The Internet can bring together like-minded people who want to discuss their favourite topics. There are chat rooms for certain sports, types of music, styles of art, in fact, just about any interest you can imagine, and many that you can't! Whatever unusual interest you might have, if you search on the Internet, there is a good chance that you will find someone, somewhere in cyberspace, willing to talk to you about it-right now.
However, there are problems with going online. It is possible for cyber-criminals to steal information such as credit card details while you are online, and there is always the chance that a new friend is not who he or she claims to be. One girl was really disappointed when she discovered that her new cyberfriend who wrote poems for her, was actually copying all the poems from magazines. But for all the problems that might come up, instant messaging services and chat rooms are here to stay, putting in touch with friends, family and strangers of similar interests.
1.People use the Internet to .
A. chat to friends and meet family
B. meet strangers and write poems
C. chat to friends, family and strangers
2.What does anonymity (para. 2) mean?
A. The state of being unknown.
B. The state of being friendly.
C. The state of being online.
3.What types of topics will people discuss on the Internet?
A. Sports, types of music, styles of art.
B. All kinds of topics.
C. Only topics that the Internet allows.
4.What is an example of problems with going online?
A. Some people may send you poems copied from magazines.
B. Your credit card details could be stolen.
C. There might be no one to chat with.

We take showers and use the toilet every day to get rid of bodily waste. Our brains also need to take a bath every day. How can they do it?
A 2013 study found the answer. Researchers at the US University of Rochester studied the brains of mice and discovered that they cleaned themselves while the mice slept. A kind of fluid (液体) in the brain, called cerebral spinal fluid (CSF, 脑脊液), was found to increase dramatically (显著地) during sleep, washing away waste proteins that had been building up between brain cells in waking hours.
“This study shows that the brain has different functional states when asleep and when awake,” Maiken Nedergaard, the lead researcher, told NBC News. It also explains why we can’t seem to think clearly after a sleepless night while a good night’s sleep leaves us feeling sharp and refreshed.
Now a new study, published on Oct. 31 in Science, digs a little deeper into our brains’ self-cleaning procedure. Instead of mice, this time humans were the test subjects.
Researchers at Boston University, US, monitored the brainwaves of 13 healthy adults who were sleeping, using accelerated FMRI (核磁共振成像), which is capable of recording faster changes inside the brain than a regular FMRI machine. They found that every 20 seconds, blood flowed out of the brain, making room for a large amount of CSF to come in and “clean”. This cycle coincided with (与....一致) the rhythm of the brain’s slow waves—an electrical activity that happens when we’re in a deep sleep.
It’s still unknown how these brain activities are connected. But the mere fact that they are connected is exciting enough, since it allows researchers to piece together (拼凑出) possible new explanations for misunderstood diseases.
For example, slow-wave sleep has been proven to play a role in strengthening our memories. This may explain why people with Alzheimer (阿尔茨海默病) often have fewer and weaker slow brainwaves. Based on this new study, there could be one more explanation for diseased brains: They are not clean.
Nedergaard, leader of the 2013 study, is also excited about the new findings. “Maybe the most important take-home message is that sleep is a serious thing,” she told Scientific American. “You really need to sleep to keep a healthy brain because it links electrical activities to a practical ‘housekeeping’ function.”
1.What did the researchers find when they studied the brains of mice?
A.CSF in their brains decreased when the mice slept.
B.More waste proteins were produced in their brains during sleep.
C.CSF carried away waste proteins in their brains during sleep.
D.The more CSF was in their brains, the fewer proteins were there.
2.What did the researchers discover when they monitored human brainwaves?
A.It took 20 seconds for CSF to clean brains.
B.Brains were “cleaned” when blood flowed out.
C.The rhythm of the brain was slower than that of CSF.
D.The brains worked more slowly when asleep.
3.What are the last three paragraphs mainly about?
A.The significance of the research.
B.The features of slow-wave sleep.
C.The importance of having a good sleep.
D.The connections between these brain activities.

Future history books might record that we were robbed of the use of our eyes. In our hurry to get from one place to another, we fail to see anything on the way, Air travel gives you a bird’s eye view of the world ---or even less if the wing of the aircraft happens to get in your way. When you travel by car or train, you are moving so quickly that you do not see the countryside clearly. Car drivers are forever thinking about going on and on. They never want to stop. Is it the great motorways that attract them, or what? And as for sea travel, it hardly deserves mentioning. It is perfectly summed up in the words of the old song: “I joined the navy to see the world, and what did I see? I saw the sea.” You mention the place names in the world like EI Dorado, Kabul and someone is sure to say, “I have been there”, meaning I drove through it at 100 miles an hour on the way to somewhere else.
When you travel at high speeds, the present means nothing: you live mainly in the future because you spend most of your time looking forward to arriving at some other place. But actual arrival, when it is achieved, is meaningless. You want to move on again. By traveling like this, you suspend (中止) all experience; the present stops being a reality: you might just as well be dead.
The traveler on foot, on the other hand, lives constantly in the present. For him traveling and arriving are one and the same thing: he arrives somewhere with every step he makes. H e experiences, the present moment with his eyes, his ears and the whole of his body. At the end of his journey he feels a delicious physical tiredness. Satisfying sleep will be his: the just reward of all true travelers.
1.The underlined words “get in your way” in Paragraph I can be replaced, by ____.
A. block your sights
B. expand your range of vision
C. prevent you from going out of the plane halfway
D. make your travel continue
2.What does the author think of the travelers mentioned in Paragraph 1?
A. They get a good view of the landscape.
B. They make full use of their eyes.
C. They fail to see the scenery with their heart.
D. The y are eager to see everything on the way.
3.Why does “the present”mean “nothing ”when we travel at high speeds?
A. Because we change our aims all the time.
B. Because we are eager to go to another place.
C. Because we are looking forward to the future life.
D. Because we cannot enjoy the experience we have had.
4.What would be the best title for the passage?
A. Different travelers B. The use of eyes
C. Ways of traveling D. True traveling
