2、 every continent except Antarctica.Youve probably seen a Venus flytrap. Its often sold in museum gift stores, department stores, and even supermarkets. A small plant, it grows 6 to 8 inches tall in a container. At the end of its stalks(茎)are specially modified leaves that act like traps. Inside each
3、 trap is a lining of tiny trigger(触发)hairs. When an insect lands on them, the trap suddenly shut. Over the course of a week or so, the plant feeds on its catch.The Venus flytrap is just one of more than 500 species of meat-eating plants, says Barry Meyers-Rice, the editor of the International Carniv
4、orous Plant Societys Newsletter. Note: Despite any science-fiction stories(科幻小说)you might have read, no meat-eating plant does any danger to humans.Dr. Meyers-Rice says a plant is meat-eating, only if it does all four of the following: attract, kill, digest, and absorb some form of insects , includi
5、ng flies, butterflies, and moths. Meat-eating plants look and act like other green plants-well, most of the time.All green plants make sugar through a process called photosynthesis(光合作用). Plants use the sugar to make food. What makes meat-eating plants different is their bug-catching leaves. They ne
6、ed insects for one reason: nitrogen(氮). Nitrogen is a nutrient that they cant obtain any other way. Why?Almost all green plants on our planet get nitrogen from the soil. Meat-eating plants cant. They live in places where nutrients are hard or almost impossible to get from the soil because of its aci
7、dity(酸度). So theyve come to rely on getting nitrogen from insects and small animals. In fact, nutrient-rich soil is poisonous to meat-eating plants. Never fertilize(施肥)them! But dont worry, either, if they never seem to catch any insects. They can survive, but theyll grow very slowly.64. Venus flytr
8、apA. is a small plant which grows in a container.B. is a kind of plant which gets hungry easily.C. can attract, kill, digest and absorb some form of insects.D. grows 6-8 inches tall65.

The reason why Venus flytrap needs flies is that it needs to get nutrient from them.D. Green plants make
11、sugar at night.68.

The first sensible lesson is that you shouldnt bother trying to find your way in the dark at all, but
12、 just stay put until dawn. Because then you wont trip over things? No, mainly because youll have an idea of direction. The sun rises in the east. But you will be amazed at how many people forget they know that. Apparently, the area underneath a holly bush provides a good makeshift shelter they are t
13、hick, and evergreen. The next thing to do or rather not to do is panic, for the obvious reason that unless there is someone there to hear you scream, it will get you nowhere. Just try to think of nice, happy things.There is always a point in films when a person who is lost in the desert or the snow,
14、 dehydrated(脱水的) and exhausted, comes across a set of their own footprints and realizes they have just walked in a huge, round circle. It is wrong to owe it to the unequal strengths or different lengths of your legs. Experiments prove that, without the sun or the moon (or landmarks) as a fixed guide
15、, lots of small errors add up over time so the brain cant correctly identify the “straight ahead” direction. To just get out of somewhere, pick a spot on the horizon and just head for it.There are several ways to find directions in the dark, and by far the best is to establish north using the stars.
16、 Most people can identify the Plough, which is part of Ursa Major. It looks a lot like a saucepan. The Plough rotates through the sky, but lets imagine the saucepan lying horizontally (水平地), with its handle on the left. You need to trace a line from the star at the right-hand base of the pan, throug
17、h the star at the right-hand rim (边沿), and follow it upwards; the north star is roughly five times the distance between those two “pointer” stars. Then drop a vertical line from the North Star to the horizon and thats north.“Tonight is very cloudy and I cant see the Plough.” Maybe luckily, it is qui
18、te windy. Keep in mind that almost all of our weather comes from a south-westerly direction. (This only works if you are in the British Isles). To find the direction, you can throw light bits of dried-out grass in the air and see which way they blow; or, if there are clouds and patches of clear sky,
19、 see which way they blow across the stars. You can also get an idea of direction from leggy plants. If they look as if they have been blown over, they will probably be pointing north-east. If they are simply leaning in one direction as they grow, theres a good chance that is south (they will be reac
20、hing towards the sun). The last thing to do is to judge your direction and off you go.12. What might be the best title of the passage ?A. How to survive in the forestB. How to protect yourself in the forest C. How to direct your way out of the wildD. What to do if you are lost13. Which of the follow
