A man who is a pure scientist is primarily interested in doing his research 7 .He is not necessarily working 8 that his findings can be used. An inventor or one interested in applied science is all trying to make something that has a concrete use. He may try to solve a problem by 9 the theories 10 science or by experimenting through trial and error. Regardless of his method, he is working to obtain a 11 result: the construction of a harvesting machine, the burning of a light bulb（灯泡）, or one of 12 other objectives. Most of the people who 13 the machines of the Industrial Revolution were inventors, not trained scientists. A few were both scientists and inventors.

Today the scientific community is in almost total agreement that the earth’s climate is changing and that this represents a huge threat to the planet and to us. According to a survey, with only 69% accepting the earth is warming— only 1 in 4 Americans see global warming as a major threat, public opinion ________ the scientific conclusion.
Climate scientists and campaigners have long debated how to better communicate the message to nonexperts so that climate science can be ________ into action. According to Christopher Rapley, the usual tactic(策略) of climate experts to provide the public with information isn’t________ because “it does not address key potential causes.” We are all exposed to the evidence of climate change on an almost a daily basis. The information is almost ___________.
Then what’s wrong? _______our brains.
Daniel Gilbert mentioned our brains’ failure to accurately notice gradual change. Robert
Gifford also _________the point about our brains’ difficulty in grasping climate change because of limited cognition and social ______ with other people (“Why should we change if X won’t?”) “ A more powerful barrier is the ___________ of perceived （感知的）behavioral control; ‘I’ m only one person; what can I do ?’ is certainly a big one. For many, the first challenge will be in recognizing barriers _____ they can overcome them”
But for those of us who understand that climate change is a problem yet make little effort
to cut the number of overseas trips we make or the amount of meat we consume, neither the uncaring attitude nor denial really explains the _________between our actions and beliefs. Lertzman has come to the conclusion that the conflict between ________ both the planet and our way of life is too painful to bear. “When we don’t ________ the pain of that, that’s when we get ______and can’t move forward.” Lertzman refers to this ________ as “environmental melancholia(忧郁症),” and points out that there’s a lot to be said for providing a means______ acceptable to talk about.”
Rosemary Randall suggests that climate change is such a(n) __________ subject that it “can raise fears and anxieties that people feel have no_________ in polite conversation.”
Lertzman says the community has been slow to realize the value of psychology. Gifford says otherwise,________—“ climate change, and not mental health, is the biggest psychological problem”
Despite the pain, shame, difficulty in fully addressing climate change, both Lertzman and Gifford are still _______ about our ability to face up to the challenge. “There can’t be anything about the human mind that stops us struggling with these issues , given that so many people ______ are — maybe that’s what we should be focusing on instead.” says Lertzman.

People do not analyse every problem they meet. Sometimes they try to remember a solution from the last time they had a 36 problem. They often accept the opinion or ideas of other people. Other times they begin to act without 37 ; they try to find a solution by trial and error. However, when all of these methods 38 , the person with a problem has to start analysing. There are six 39 in analysing a problem.
40 , the person must recognize that there is a problem. For example, Sam’s bicycle is broken, and he cannot ride it to class as he usually does. Sam must 41 that there is a problem with his bicycle.
Next the person must 42 the problem. Before Sam can repair his bicycle, he must know why it does not work. For example, he must 43 the parts that are wrong.
Now the person must look for 44 that will make the problem clearer and lead to 45 solutions. For example, suppose Sam 46 that his bike does not work because there is something wrong with the brakes. 47 , he can look in his bicycle repair book and read about brakes, talk to his friends at the bike shop, or look at his brakes carefully.
After 48 the problem, the person should have several suggestions for a possible solution. Take Sam as an example 49, his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones.
In the end, one 50 seems to be the solution to the problem. Sometimes the 51 idea comes quite 52 because the thinker suddenly sees something in a 53 way. Sam, for example, suddenly sees there is a piece of chewing gum stuck to a brake. He immediately hits on the solution to his problem: he must 54 the brake.
Finally the solution is 55 . Sam does it and finds his bicycle works perfectly. In short he has solved the problem.

We all need a healthy environment. , we produce waste every day and it harm to our environment. Though we are young, we can still do to help. In fact, even the simplest everyday activities can make a real to the environment. Here are some ideas for you to live a life.
Remember these three : reduce, reuse and recycle.
Reduce means “use less”. Don't things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think if it is really or maybe the one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from a country.
Reuse means “use again”. Use things for possible. When we buy things, make sure that they a long time. We should take care of them they will last, and we should them if we can instead of throwing them away and buying new ones. Don't use a paper cup or a paper bag. It’s better to use a china cup and a lunch box because you can use them .
Recycle means “change things into something else”. Although it energy to change something into something else, it’s better than things or burning them. Find out can be recycled in your neighborhood and take part in recycling programs. We should also buy made from recycled materials, such as recycled paper, to help save .

It is interesting how NASA(美国航天航空局) 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.

We have known for a long time that flowers of different plants open and close at different times of day. This is so 1 that there seems to be no need to ask the reason for it. Yet no one 2 understands why flowers open and close like this at particular times. The process is not as 3 as we might think, as recent experiments have shown. In one study, flowers were kept in constant 4 . We might expect that the flowers, without any information about the time of day, did not open as they 5 do. As a matter of fact, they 6 to open at their usual time. This suggests that they have some mysterious(神秘的) way of k
nowing the 7 . Their sense of time does not 8 information from the outside world; it is, so to speak, inside them, a kind of “inner clock”.
This 9 may not seem to be very important. However, it was later found that not just plants but also 10 , including man, have this “inner clock” which 11 the working of their bodies and influences their activities. Men, then, are also influenced by this mysterious 12 . Whether we wish it or not, it affects such things in our life as our need for sleep, our need for food.
In the past, this did not really 13 because people lived in natural condition. In
the 14 world, things are different; now there are spacemen, airplane pilots and, in ordinary life, a lot of people who have to work at night. It would be very 15 , then, to know more about the “inner clock”. Such things as flowers might help us understand more about ourselves.
