B
Jungle country is not friendly to man, but it is possible to survive there. You must have the right equipment and you must know a few important things about woodcraft. Then your chances of staying alive are very good.
No one should go into the jungle without the right equipment. You need light weight clothing, a good knife, and a compass. Fishhooks and a line, a rifle, matches in a waterproof container and a poncho are necessary too. So is a mosquito net to protect the head.
In the jungle you can get hopeless lost within five minutes after leaving a known landmark. That is why you should always carry a compass. In open country, during the day, you can tell which way o go by studying the sun. At night the stars are sure guides o direction. But in most places the jungle rooftop is so thick that it is impossible to see the sun or the stars. Again and again you must check your position by the compass.
Keep alert. Watch the ground in front of you carefully. Stop and listen now and again. Avoid haste, and rest often. In a place that is hot and humid, the person who sets a fast pace will soon become tired. A steady, even pace is wisest in the long run.
If you lose your way, don’t panic. Try to desire how long it has been since you were sure of your position. Mark the spot where you are with blazes on a tree. Put them on four sides of the tree, so that you will be able to see them from any direction. Then you can begin retracing your steps, knowing that you can always find the spot from which you started. Except in an emergency, never try to travel through the jungle at night.
Whenever possible, it is wise to follow streams and rivers that are going in your general direction. This may cause you many extra miles of travel. But in the end it will save time and energy. Nothing is more exhausting than hacking a trail cross-through umbrella jungle.
If a river is broad and deep and has no rapids, rafting is the best means of travel. Bamboo grows along the banks of many jungle streams. Since it is hollow and extremely strong, it makes a perfect raft.
Surviving in the jungle is a science. The jungle people have become perfect in this science, and you can too. Learn as much as you can about what to expect in the jungle. Make sure you have the right equipment. Then no part of the jungle will be able to “live off” it for a long time.
1. The author probably advises against traveling at night because ________.
one tends to move too slowly at night

it is more difficult to check your position
2. Following streams and rivers will help you to ________.

Walk through the Amazon rainforest today and you will find it is steamy ,warm ,damp and thick .But if you had been around 15,000 years ago, during the last ice age ,would it have been the same ?For more than 30 years, scientists have been arguing about how rainforests like the Amazon might have reacted（反应）to the cold ,dry climates of the ice ages ,but until now ,no one has reached a satisfying answer.
Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to slow global warming . Currently the trees in the Amazon take in around 500 million tonnes of CO2 each year; equal to the total amount of CO2 giving off in the UK each year. But how will the Amazon react to future climate change? If it gets drier ,will it still survive and continue to draw down CO2 ?Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past.
Unfortunately ,getting into the Amazon rainforest and collecting information are very difficult .To study past climate ,scientists need to look at fossilized pollen ,kept in lake muds .Going back to the last ice age means drilling deep down into lake sediments （沉淀物）,which requires specialized equipment and heavy machinery .There are very few roads and paths ,or places to land helicopters and aeroplanes .Rivers tend to be the easiest way to enter the forest ,but this still leaves vast areas between the rivers completely unsampled（未取样）.So far ,only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change.
64．The underlined phrase “mopping up” in the second paragraph means .
A．cleaning up B．taking in C．wiping out D．giving out
65．How will the Amazon rainforest react to future climate change?
A．It’ll get drier and continue to remove CO2 .
B．It’ll remain steamy ,warm ,damp and thick .
C．It’ll get warmer and then colder and drier.
D．There is no exact answer up to present.
66．What’s the main idea of the last paragraph?
A．It’s important to drill deep down into lake sediments to collect information.
B．It’s impossible to prove how climate changes in the Amazon rainforest.
C．It’s hard to collect information for studies of the past climate in the Amazon rainforest.
D．It’s necessary to have specialized equipment and machinery to study the past climate.
67．The best title for this passage may probably be .
A．Studies of the Amazon B．Climates of the Amazon
C．Secrets of the Rainforests D．Changes of the Rainforests

Real people who live in a 3 world do real things; in other words, the stories are about people just like us doing what we do. Other stories, such as the Harry Potter books, are not 4 .They characters and creatures that are very different from us and do things that would be 5 for us.
But there is more to books and writing than this. If we think about it, even realistic writing is only 6 . How can we tell the difference between what is real and what is not real? For example, when we read about Harry Potter, we 7 seem to learn something about the real world. And when Harry studies magic at Hogwarts, he also learns more about his real life than 8 . Reading, like writing, is an action. It is a way of 9 . When we read or write something, we do much more than simply look at words on a page. We use our 10 which is real--–and our imagination – which is real in a different way–--to make the words come to life in our minds.
Both realism and fantasy（幻想） 11 the imagination and the “magic” of reading and writing to make us think. When we read 12 realistic, we have to imagine that the people we are reading about are just like us, even though we 13 that we are real and they are 14 .It sounds 15 , but it works. When we read, we fill in missing information and 16 about the causes and effects of what a character does. We help the writer by 17 that what we read is like real life. In a way, we are writing the book, too.
Most of us probably don’t think about what is going on our 18 , when we are reading. We pick up a book and lose 19 in a good story, eager to find out what will happen next. Knowing how we feel 20 we read can help us become better readers, and it will help us discover more about the real magic of books.

查看习题详情和答案>>阅读下列短文，从每题所给的四个选项A、B、C和D中，选出最佳选项。
With the entry of the twenty-first century, we can't help asking ourselves whether it is possible to persuade mankind to live without war. War is an ancient institution (惯例) which has existed for at least six thousand years. It was always not only ruinous but also foolish, however, in the past the human race managed to live with it. As we know, the war nowadays is quite different from what it used to be, and its ruination has been incomparably doubled. In some way, either man will abolish(废除) war, or war will abolish man. For the present, it is nuclear weapons (武器) that cause the most serious danger, but bacteriological or chemical weapons may, before long, offer an even greater danger. If we succeed in abolishing nuclear weapons, our work will not be done. It will never be done until we have succeeded in abolishing war. To do this, we need to persuade mankind to look upon international disputes(争端) in a new way, not as competition of force, in which the victory goes to the side which is most skillful in killing people, but by settlement in accordance with agreed law. It is not easy to change very old mental habits, but this is what must be attempted.
There are those who say that the acceptance of this or that ideology(意识形态) would prevent war. I believe this to be a terrible mistake. All ideologies are based upon dogmatic(武断)statements which are, at best, doubtful, and at worst, totally false. Their supporters believe in them, so they are willing to go to war in support of them.
The movement of world opinion during the past few years has been very largely such as we can welcome. It has become a commonplace that nuclear war must be kept away. Of course very difficult problems remain in the world, but the spirit in which they are being approached (接近) is a better one than it was some years ago. It has begun to be thought, even by the powerful men who decide whether we shall live or die, that talks should reach agreements even if both sides do not find these agreements wholly satisfactory. It has begun to be understood that the important fight nowadays is not between different countries, but between man and the atom bomb.
1．This passage suggests that war is now ________ in the past.
[ ]
2．From paragraph 2 we learn that the writer of the passage ________.
[ ]
A．is a supporter of some modern ideologies
B．does not think that the acceptance of any ideology could prevent war
C．believes that the acceptance of some ideologies could prevent war
D．does not doubt the truth of any ideologies
3．According to the writer, ________.
[ ]
A．war is the only way to solve international disputes
B．war will be less dangerous because of the improvement of modern technology
C．it is impossible for people to live without war
D．war must be abolished if man wants to continue to live
4．The last paragraph suggests that ________.
[ ]
A．international agreements can be reached more easily now
B．man begins to realize the danger of nuclear war
C．nuclear war will surely not take place
D．world opinion welcomes nuclear war
