Can trees talk? Yes--but not in words. Scientists have reasons to believe that trees do communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree（柳树）attacked in the woods by caterpillars（毛毛虫）changed the chemistry of its leaves and made them taste so terrible that the caterpillars got tired of the leaves and stopped eating them. Then even more astonishing, the tree sent out a special vapour--a signal causing its neighbours to change the chemistry of their own leaves and make them less tasty.
Communication, of course, doesn't need to be always 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 messages?
（1）When attacked, a willow tree will protect itself by _______.
[ ]
A. changing its leaves' chemistry
B. changing its leaves' colour
C. talking to caterpillars
D. sending out a special vapour
（2）From the passage we know that caterpillars _______ .
[ ]
A. like willow trees
B. enjoy eating fallen leaves
C. feed on willow tree leaves
D. could communicate with willow trees
（3）Caterpillars will stop eating willow tree leaves which _______ .
[ ]
A. have a chemical change and become tasteless
B. have a pleasant taste
C. are being attacked
D. are communicating
（4）According to the passage, how do willow trees communicate with each other?
[ ]
A. They talk in words.
B. They send out a special vapour.
C. They wave their leaves.
D. They make special sounds.
（5）According to the passage, bees communicate with each other by ______ .
[ ]
A. talking
B. making unusual sounds
C. singing songs
D. flying in certain patterns

Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age.
Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception(观察力) of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.
The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time.
Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here’s where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles — making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles — so it appeared to be smaller than the real smaller orange circle.
When young children aged 4 to 6 looked at these tricky pictures, they weren’t fooled — they were still able to find the bigger circle with roughly the same accuracy as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one, and adults got it wrong most of the time.
As children get older, Doherty said, their brains may develop the ability to identify visual context. In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they’re more likely to fall for this kind of visual trick.
1．Doherty and his team of scientists did an experiment to evaluate .
A．children’s and adults’ eye-sight
B．people’s ability to see accurately
C．children’s and adults’ brains
D．the influence of people’s age
2．When asked to find the larger circle, .
A．children at 6 got it wrong 79 % of the time with no gray ones around
B．only adults over 18 got it right 95% of the time with gray ones around
C．children at 4 got it right about 79 % of the time with gray ones around
D．adults got it right most of the time with gray ones around
3．According to the passage, we can know that .
A．a smaller orange circle appears bigger on a white background
B．an orange circle appears bigger than a gray one of the same size
C．a circle surrounded by other circles looks bigger than its real size
D．a circle surrounded by bigger ones looks smaller than its real size
4．Visual context may work when children get older than .
A．4 B．6 C．10 D．18
5．Why are younger children not fooled?
A．Because they are smarter than older children and adults.
B．Because older people are influenced by their experience.
C．Because people’s eyes become weaker as they grow older.
D．Because their brain can hardly notice related things together.

第二部分阅读理解
Can you imagine a classroom which misses the one thing that’s long been considered a necessary part to reading and writing? Paper. No notebooks, no textbooks, no test paper. Nor are there any pencils or pens, which always seem to use up ink at the critical(关键的) moment.
Such a “paperless classroom” is one that more and more schools are trying to get.
Students never do any handwriting in the class. Instead, they use specially-designed computers. The teacher downloads texts from Internet libraries and sends them to every student’s personal computer.
Having computers also means that students can use the Internet. They can look up information on any subject they’re studying, from maths to social science.
A middle school teacher Judy Harrell in Florida, US, described how her class used the Web to learn about the war in Iraq in 2003.
“We could touch every side of the country through different sites: from the forest to refuges(难民营),” she said. “Using a book that’s three or four years old is impossible.”
And exams can go online too. At a high school in Tennessee, US, students take tests on their own computers. The teacher records the grades on the network for everyone to see and then copies them to his own electronic grade book.
A paperless classroom is a big step towards reducing the waste of paper. High school teacher Stephanie Sorrell in Kentucky, US, said she used to give about 900 pieces of paper each week to each student.
“Think about the money and trees we could save with the computers,” she said.
But, with all this technology, there’s always the risk that the machines will break down. So, in case of a power failure or technical problems, paper textbooks are still widely available for these hi-tech students.
41．What does the underlined sentence “use up ink at the critical moment” in the 1st paragraph mean?
A．Pens use ink, while pencils don’t.
B．Pens get lost easily at any moment.
C．Pens may have little or no ink at the key moment.
D．Pens may not write well at the critical moment.
42．What did the middle school teacher show while using the example of her class?
A．the Web could take them everywhere.
B．the Web taught them a lot.
C．the Web is a good tool for information.
D．the Web, better than the textbooks, can give the latest information.
43．What does the phrase “break down” in the last paragraph mean?
A．Break up. B．Stop working. C．Fall down. D．Lose control.
