20.Passage 2
Sam and Joe were astronauts. There was once a very dangerous trip and the more experienced astronauts knew there was only a small chance of coming back alive (活着). Sam and Joe, however, thought it would be exciting though a little dangerous. “we’re the best men for the job,” they said to the boss. “There may be problems, but we can find the answers.” “They’re the last people I’d trust,” thought the boss. “But all the other astronauts have refused to go.”
Once they were in space, Joe had to go outside to make some repairs. When the repairs were done, he tried to get back inside the spaceship. But the door was locked. He knocked but there was no answer. He knocked again, louder this time, and again no answer came. Then he hit the door as hard as he could and finally a voice said, “Who’s there?” “It’s me! Who else could it be?” shouted Joe. Sam let him in all right but you can imagine that Joe never asked to go on a trip with Sam again!

25.Passage 1
Can trees talk? Yes, but not in words. Scientists have reason to believe that trees do communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree attacked in the woods by caterpillars (毛虫) changed the chemistry of its leaves and made them taste so terrible that they got tired of the leaves and stopped eating them. Then even more astonishing, the tree sent out a special smell—a signal causing its neighbors to change the chemistry of their own leaves and make them less tasty.
Communication, of course, doesn’t need to be in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar (花蜜) for honey. So why shouldn’t trees have ways of sending message?
(1).It can be concluded from the passage that caterpillars do not feed on leaves that ______.
A.are lying on the ground
B.have an unpleasant taste
C.bees don’t like
D.have an unfamiliar shape
(2).The willow tree described in the passage protected itself by ______.
A.growing more branches

(4).According to this passage, bees communicate by ______.
A.making special movement
B.touching one another
C.smelling one another
D.making unusual sound
(5).The author believes that the incident described in the passage ______.
A.cannot be taken seriously
B.should no longer be permitted
C.must be checked more thoroughly
D.seems completely reasonable

40.Do you find getting up in the morning so difficult that it’s painful? This ## called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy ## .
