Jungle(丛林) 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(山林野外知识). Then your chances of staying alive are very good.
No one should go into the jungle without the right equipment. You need lightweight clothing, a good knife, and a compass. Fishhooks and a line,a rifle,matches in a waterproof container and a poncho(雨披) are necessary too. So is a mosquito net(蚊帐) to protect the head.
In the jungle you can get hopelessly lost within five minutes after leaving known landmark(地界碑). That is why you should always carry a compass. In open country during the day, you can tell which way to go by studying the sun. At night the stars are sure guides to 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(警惕的). Watch the ground in front of you carefully. Stop and listen now and again. Avoid haste(匆忙), and rest often. In a place that is hot and humid(潮湿的), the person who sets a fast pace will soon become tired. A steady and even pace is wisest in the long run.
If you lose your way, don't panic. Try to decide 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(going back exactly the way you have come), knowing that you can always find the spot from which you started. Except in an emergency, never try to travel 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 (extremely tiring) than hacking(cutting) a way through unbroken jungle.
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 seem completely or frightening. In fact, you will be able to “live off” it for a long time.
【小题1】To keep alive in the jungle, you should make it clear that the right equipment is _________.

A.more important than a knowledge of woodcraft
B.less important than a knowledge of woodcraft
C.just as important as a knowledge of woodcraft
D.not as important as a knowledge of woodcraft
【小题2】If you lose your way in the jungle, which of the following can NOT be done?
A.Check your position by the compass again and again.
B.Decide how long ago it was that you got lost.
C.Tell which way to go by studying the sun/the stars.
D.Mark blazes on four sides of a tree and be sure to see them from any direction.
【小题3】The author is strongly against traveling at night probably because __________.
A.one tends to move too slowly at night
B.some animals will attack you
C.emergencies occur most frequently at night
D.it is more difficult to check your position

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

It’s summertime-time once again for mosquitoes to make their appearance. And once they appear, mosquitoes are a total pain. They land on you,  bite you, suck out some blood and leave behind an itchy welt(发痒的红肿).

  1  Female mosquitoes must find blood in order to reproduce, so mosquitoes come equipped with finely tuned sensors to help them locate the blood they need.

Mosquitoes’ weapons

Mosquitoes have perfected three different types of sensors. First, mosquitoes can sense several different chemicals. Mosquitoes can smell carbon dioxide and lactic acid(乳酸)up to 100 feet away.   2 

Second, mosquitoes have very good eyesight. If you are wearing clothing that contrasts with the background, and if you move while wearing that clothing, mosquitoes can see you. It’s a good bet that anything moving is alive, and therefore full of blood.

Finally, mosquitoes come equipped with temperature sensors, so they can find warm-blood mammals and birds very easily.

  3  The female mosquito sticks her proboscis(喙)into you. She sucks about five microliters of your blood into her abdomen.

After she has bitten you, some saliva(唾液)remains in the wound.   4  The area swells and you tich. Eventually, the selling goes away, but the itch remains until your immune cells break down the saliva proteins.

Our defense methods

Because mosquitoes are both a nuisance(讨厌的东西) and a danger, people prefer to stay away from mosquitoes. One way to do that is to use a chemical called DEET, which seems to black a mosquito’s chemical sensors.   5  In some cities there are even trucks that drive around town to spray for mosquitoes. Finally there are to traps. The most popular traps turn propane(丙烷) into carbon dioxide and warmth to attract mosquitoes. Over time, by catching large numbers of mosquitoes, these traps can cause the collapse of the mosquito population in the area.

A.Another way to control mosquitoes is with insecticides(杀虫剂) that kill them.

B.How mosquitoes work is unknown to most of us.

C.Once a mosquito lands on you, it is time to bite.

D.Some bites of mosquitoes are more serious than you thought.

E. Mammals and birds give off these gases as part of their normal breathing.

F. The proteins from the saliva create an immune response from your body.

G. But if you ignore the fact that mosquitoes are so annoying they really are amazing.
