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 vapor—a signal causing its neighbors to change the chemistry of their own leaves and make them less tasty.
Communication, of course, does not need to be in words. We can talk 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 for honey. So why shouldn’t trees have ways of sending messages?
1．It can be inferred from the passage that caterpillars do not feed on leaves that .
A．have an unpleasant taste
B．are lying on the ground
C．have an unfamiliar shape
D．bees don’t like
2．According to the passage, the willow tree was able to communicate with each other by .
A．waving its branches B．giving off a special vapor
C．dropping its leaves D．changing the color of its trunk
3．According to the passage, bees communicate by .
A．touching one another B．smiling one another
C．making special movement D．making unusual sound
4．The author believes that the incident described in the passage .
A．cannot be taken seriously B．seems completely reasonable
C．should no longer be permitted D．must be checked more thorough

举一反三
The plan: turn Mars into a blue world with streams and green fields, and then fill it with creatures (生物) from the earth. This idea may sound like something from a science fiction (科幻小说), but it is actually being taken seriously by many researchers.
This suggested future for the “red planet” will be the main topic for discussion at an international conference hosted by NASA (美国宇航局) this week. Leading researchers as well as science fiction writers will attend the event. It comes as NASA is preparing a multibilliondollar Mars research programme. “Turning Mars into a little earth has long been a topic in science fiction,”said Dr Michael Meyer, NASA’s senior scientist for astrobiology (太空生物学). “Now, with scientists exploring the reality, we can ask what are the real possibilities of changing Mars.”
Most scientists agree that Mars could be turned into a little earth, although much time and money would be needed to achieve this goal.
But many experts are shocked by the idea. “We are destroying our own world at an unbelievable speed and now we are talking about ruining another planet,” said Paul Murdin, of the Institute of Astronomy, Cambridge, UK. Over the past months, scientists have become increasingly confident they will find Martian life forms. Europe and America’s robot explorers have found proof that water, mixed with soil, exists in large amounts on the planet.
In addition, two different groups of scientists announced on March 28 that they had found signs of methane (甲烷) in the Martian atmosphere (大气). The gas is a waste product of living creatures and could be produced by microbes (微生物) living in the red planet’s soil.
But scientists such as Dr Lisa Pratt, a biologist at Indiana University, say that these microbes will be put in danger by the little earth project. “Before we have even discovered if there is life on Mars, we are talking about carrying out projects that would destroy all these native lifeforms, all the strange microbes that we hope to find buried in the soil,” said Dr Pratt. This view is shared by Monica Grady, a planetary scientist at the Natural History Museum, London. “We cannot risk starting a global experiment that would wipe out the precious information we are looking for.” she said， “This is just wrong.”
5. The passage is about________.
A. a plan turning Mars into a little earth
B. the necessity of changing Mars
C. Mars supporting life
D. finding water in the Mars
6. Which of the following is NOT the reason why some scientists are against the plan?
A. The project would wipe out all the native lifeforms on the Mars.
B. The project will cost too much money and work.
C. We would ruin Mars.
D. We are destroying our own world at an unbelievable speed.
7. We can infer from the passage that________.
A. water is a crucial factor for life
B. the project will have little effect on the native lifeforms supposed to live on the Mars
C. Monica Grady is in favour of carrying out the little earth project
D. the idea turning Mars into a little earth is nothing but a science fiction
8. Which of the following supports the conclusion of microbes living in the Mars’s soil?
A. Scientists found liquid water in the Mars.
B. Scientists found signs of methane in the Martian atmosphere.
C. Scientists found a lot of good soil on the Mars.
D. Scientists found some creatures living on the Mars.
Who has deprived the children"s happiness of learning???
Children are born with a natural desire of learning. They are curios and concerned about 36 around them. They are 37 to learn anything that amazes them. They have so many 38 that they keep on asking. They can bore the 39 all day long with many 40 questions which they will never feel bored with. Why? This is because learning is their 41 , perhaps an instinct of human beings. They just can"t help.

Students will need to use all of their skills in order to understand the reading selections in Reader’s Choice.
The book 36 many types of selections on a wide 37 of topics. These selections provide practice on 38 different reading skills to get the 39 of the writer. They also give students 40 in four basic reading skills: skimming, scanning, reading for 41 comprehension, and critical reading.
Skimming involves reading quickly through a text to get an overall idea of its contents. This kind of rapid reading is 42 when you are trying to decide 43 careful reading is desirable or when there is not 44 to read something carefully.
Like skimming, scanning is also quick reading. 45 , in this case the search is more 46 .To scan is to read quickly in order to 47 specific information. When you read to find a 48 date, or number you are scanning.

Critical reading demands that a reader 53 judgments about what he or she reads. This kind of reedit 54 posting and answering questions such as “Does my own experience support that of the author?”, “Do I 55 the author’s point of view?” And “Am I convinced by the author’s arguments and evidence?
