1_____ 
     Science is an amazing subject, but it's difficult to capture the true magic of science and contain it in a book.
For young learners, textbook science often looks like a lot of big, confusing terms that have to be memorized.
That is why sometimes children think that science is dry, boring and difficult. Textbooks can't help them
discover how exciting science really is. So find some other ways to help kids to develop a love of science. 
2_____
     Instead of just reading from a book about the water cycle, air pressure, chemical changes, sound waves,
fingerprints, etc., let students experience these things instead. It's much more memorable for them to discover
a principle or fact about science on their own than it is to simply be told about it. There are great resources
online that include complete lesson plans for hundreds of activities. Afterwards, a brief discussion can bring
the principal points home to children. In addition, an explanation of any unfamiliar terms at this point will make
a lot more sense. 
3_____ 
     Science is all around. Taking time to look at the world and to discuss what is seen, encourages scientific
observation and a love of learning. Look at changing seasons, weather events, plants, pets, insects, the stars
and virtually everything else as an opportunity to help students learn more about science. 
4_____
     Real scientists record their findings. Encourage young scientists to draw pictures and write about what they
see and do. Science isn't an isolated subject. It involves reasoning, writing, math, history, art, and more. A
journal gives students a place to record the things about science that interest them most. 
5_____
     Cooking is filled with chemical reactions. Teach students about what happens when carbon dioxide bubbles
form in dough. Help them to understand mixtures by making a salad, solvents by mixing up powdered drink
mixes, colloids by making gelatin, evaporation and cloud formation by observing a boiling tea kettle. Crystals can
be observed (and grown) with salt and sugar. Liquids can be changed to solids in a freezer. The list is almost
endless.

     Although it might have happened anywhere, my encounter with the green banana started on a steep
mountain road in the central area of Brazil. I was driving up through beautiful countryside when the radiator
(水箱) began to leak. I stopped at the next village, which consisted of a small store and a few houses. People
came over to look. "That's easy to fix," a man said. He sent a boy running for some green bananas. He patted
me on the shoulder, assuring me that everything would work out. "Green bananas," he smiled. Everyone agreed. 
     We chatted casually while all the time I was wondering what they could possibly do to my radiator with
their green bananas. I did not ask them, though, as that would show my ignorance, so I talked about the beauty
of the land that lay before our eyes. Huge rock formations, like Sugar Loaf in Rio,rose up all around us. "Do
you see that tall one right over there?" asked the man, pointing to a particularly tall, slender pinnacle (尖端) of
dark rock. "That rock marks the center of the world."
     I looked to see if he was teasing me, but his face was serious. He, in turn, inspected me carefully, as if to
make sure I grasped the significance of his statement. The occasion called for some show of recognition on
my part. "The center of the World?" I repeated, trying to show interest. He nodded, "The absolute center.
Everyone around here knows it."
     At that moment the boy returned with an armful of green bananas. The man cut one in half and pressed
the cut end against the radiator jacket. The banana melted into a glue against the hot metal, stopping the leaks
instantly. I was so astonished at this that I mush have looked rather foolish and everyone laughed. They then
refilled my radiator and gave me extra bananas to take along. An hour later, after using the green banana once
more, my radiator and I reached our destination.
     It took me a little longer to fully grasp the importance of the rock which the villagers believed marked the
center of the world. I had at first doubted their claim, as I knew for a fact that the center was located
somewhere else in New England. After all, my grandfather had come from there. But gradually I realized the
village people had a very reasonable belief and I agreed with them. We all tend to regard as the center that
special place where we are known, where we know others, where things mean much to us, and where we
ourselves have both identity and meaning: family, school, town and local region could all be our center of the
world.
     The lesson which gradually dawned on me was actually very simple. Every place has special meanings for
the people in it, and in a certain sense every place represents the center of the world. The world has numerous
 such centers, and no one student or traveler can experience all of them. But once a conscious breakthrough
to a second center is made, a life-long perspective and collection can begin.
     The cultures of the world are full of unexpected green bananas with special value and meaning. They have
been there for ages, ripening slowly, perhaps waiting patiently for people to come along to encounter them. In
fact, a green banana is waiting for all of us if we would leave our own centers of the world in order to
experience other places.

1. The author stopped at a village on his way because he wanted to ____.
A. have his car repaired
B. enjoy the beautiful scenery
C. look for some bananas to fix his radiator
D. talk to some villagers to learn about their way of life
2. What's the author's reaction to the man's remarks on the center of the earth?
A. He thought the man was serious about what he said.
B. He thought that the man was telling the truth.
C. He thought that the man was telling a story.
D. He thought the man was making fun of him.
3. What does the author come to learn from the man's remarks?
A. The rock mentioned by the man is really the center of the world for everyone.
B. There are lots of such "rocks" in the world representing the center of the world.
C. There is only one center in the world that is actually in New England.
D. As a matter of fact, the center of the world does not exist in his opinion.
4. What can we infer from the last paragraph?
A. A green banana refers to a banana that is not ripe.
B. A green banana is something that can be used to repair a leaking radiator.
C. A green banana refers to a certain culture that is unknown to an outsider.
D. A green banana is something useful that we find unexpectedly.

Robots are smart. With their computer brains, they help people work in dangerous places or do difficult jobs. Some robots do regular jobs. Bobby, the robot mail carrier, brings mail to a large office building in Washington, D.C. He is one of 250 robot mail carriers in the United States. Mr. Leachim, who weights two hundred pounds and is six feet tall, has some advantages as a teacher. One is that he does not forget details. He knows each child’s name, their parents’ names, and what each child knows and needs to know. In addition, he knows each child’s pets and hobbies. Mr. Leachim does not make mistakes. Each child goes and tells him his or her name, then dials an identification (识别) number. His computer brain puts the child’s voice and number together. He identifies the child with no mistakes.

Another advantage is that Mr. Leachim is flexible. If the children need more time to do their lessons they can move switches. In this way they can repeat Mr. Leachim’s lesson over and over again. When the children do a good job, he tells them something interesting about their hobbies. At the end of the lesson the children switch Mr. Leachim off.

1.The first paragraph of the passage tells us

A. human beings are not as smart as robots

B. robots will take the place of man to rule the earth

C. we can only use robots to do some regular jobs

D. robots can help people in many different ways

2.What is the most important thing Mr. Leachim can do in his lessons?

A. To meet the needs of each student.

B. To talk to the students in different languages.

C. To keep everyone’s interest in his lessons.

D. To introduce more hobbies to the children.

3.The underlined word “flexible” probably means

A. not strict                     B. not hard

C. suitable           D. changeable

4.Which of the following statements may be TRUE according to the passage?

A. There are 250 robot teachers in the United States.

B. Mr. Leachim is run and controlled by electricity.

C. Bobby works in a large office building in Washington D.C.

D. The lessons taught by Mr. Leachim are given on a TV set.
