As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. The they become interested in the physical world around them: the plants, the
animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、職業(yè)) in science.
Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty?”
Scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious.

To face the music

Like every language, American English is full of special expressions, phrases that come from the day-to-day life of the people and develop in their own way. Our expression today is “to face the music”.

When someone says, “well, I guess I’ll have to face the music,” it does not mean he’s planning to go to the concert. It is something far less pleasant, like being called in by your boss to explain why you did this and did that, and why you didn’t do this or that. Sour music indeed, but it has to be faced. At sometime or another, every one of us has had to face the music, especially as children. We can all remember father’s angry voice, “I want to talk to you.” and only because we did not obey him. What an unpleasant business it was!

The phrase “to face the music” is familiar to every American, young and old. It is at least 100 years old. And where did this expression come from? The first explanation comes from the American novelist, James Fenimore Looper. He said, in 1851, that the expression was first used by actors while waiting in the wings to go on the stage. When they got their cue to go on, they often said, “Well, it’s time to face the music.” And that was exactly what they did — facing the orchestra which was just below them. And an actor might be frightened or nervous as he moved on to the stage in front of an audience that might be friendly or perhaps hostile, especially if he forgot his lines. But he had to go out. If he did not, there would be no play. So the expression “to face the music” come to mean “having to go through something, no matter how unpleasant the experience might be, because you knew you had no choice.”

Other explanations about the expression go back to the army. When the men faced an inspection by their leader, the soldiers would be worried about how well they looked. Was their equipment clean, shinny enough to pass the inspection? Still the men had to go out and face the music of the band as well as the inspection. What else could they do? 

Another army explanation is more closely related to the idea of facing the results and accepting the responsibility for something that should not have been done. As, for example when a man is forced out of the army because he did something terrible, he is dishonored. The band does not play. Only the drums tap a sad, slow beat. The soldier is forced to leave, facing such music as it is and facing the back of his horse.

1. How many ways does the phrase “to face the music” comes from?

A. 1        B. 2        C. 3       D. 4

2. What’s the meaning of “to face the music?”

A. To face something far less pleasant.

B. To face the stage.

C. To face the back of one’s horse.

D. To face one’s leader.

3. Which of the following is a situation of facing the music?

A. When we are playing basketball.  

B. When we are making a speech.

C. When we are having a party.

D. When we are talking with somebody. 

4. The underlined word “hostile” means _______. 

A. unfriendly               B. dislike        C. unkind                     D. unnecessary

Do you enjoy reading? Do you read newspapers or magazines? Chances are, if you do any of these activities, your pre-school child is on his way to becoming a reader.
The process of learning to read is complex, and one of the most important things to know is that parents can help their children learn to read. As children have conversations with adults, they hear both new and familiar words and their vocabulary grows.
There are many opportunities for adults and children to talk together, such as when riding in the car or in a bus, doing housework like fixing dinner, or bathing and getting ready for bed. A major part of conversation is listening. When children talk, adults listen and respond. Then children listen and respond, and so the flow of conversation happens.
Have you watched you pre-school child pretend to read to his younger sisters or brothers? Have you read his favorite story over and over? These experiences tell children that reading is fun. And when things are fun and they are repeated, your child will see letters. He begins to connect them to familiar words, especially the letters that make up his name. A natural next step for him to take is to write the letters.
When children see parents make a grocery list, they want to use a pencil and paper to make their own list. To encourage these beginning writing activities, have pencils, markers, crayons and scrap paper within your children’s reach.
The more children get connected with talking, listening, reading and writing, the easier it is for them to become active readers. While you as a parent have a big influence on these early behaviors, it is important to remember that opportunities for literacy experiences happen when you and your child share in the basic routines(日常生活)of everyday life.
【小題1】The third paragraph tells us that parents can talk with their children__________.

A.during daily routinesB.only in quiet places
C.in their spare timeD.when they are eager to walk
【小題2】During the process of learning to read, children may _________.
A.copy the action of the adults.
B.prefer to talk with those of their own age.
C.show no interest in reading at all.
D.waste a lot of paper and other materials.
【小題3】When do children want to learn to write?
A.When their parents ask them to do so.
B.When they believe they can write well.
C.When they know what they want to know
D.When they can connect letters with familiar words.
【小題4】The passage is written to _____________.
A.talk about parents’ influence on their children’s behavior
B.encourage parents to set a good example to their children
C.a(chǎn)dvise parents to make reading a part of their children’s daily life
D.make parents believe in the importance of early reading

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(觀察力) 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.
55.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
56.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.a(chǎn)dults got it right most of the time with gray ones around
57.Visual context may work when children get older than        .
A.4                           B.6                            C.10                          D.18
58.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.

Warning: reading too much Cinderella to your daughter may damage her emotional health in later life. A paper to be developed at the international congress of cognitive psychotherapy(認知心理療法) in Gothenburg suggests a link between the attitudes of women abused by their parents and early exposure to the wrong sort of fairy tales. It says girls who identified with Cinderella, Rapunzel and Beauty in Beauty and the Beast were more likely to say in destructive relationships as adults.
The theory was developed by Susan Darker Smith, a psychotherapist at the University of Derby. She interviewed 67 female abuse survivors and found that 61 put up with severe abuse because they believed they could change their partners with patience, composition and love. The same view was taken by male survivors who had been abused as children. Hardly any of the women in a control group, who had not experienced abuse, thought they could change their partners in this way.
The same view was taken by male survivors who had been abused as children. These women and men said they would leave a relationship rather than put up with abuse from a partner. Ms Darker Smith found the abused women were much more likely to identify with Cinderella and other submissive female characters in fairytales, who were later rescued by a stranger prince or hero.
Although most girls heard the stories, damage appeared to be done to those who adopted the characters as role models. “They believe if their love is strong enough they can change their parents’ behaviors,” she said.” Overexposure in children to stories that emphasize the transformational qualities of love may make women believe they can change their partners.” For example, they might never have understood the obvious flaw in the story of Rapunzel, who remained locked in a high tower until rescued by a knight on a white horse, who broke the door down. “The question,” said Ms Darker Smith, “is why she did not break the door down herself.”
【小題1】The passage is especially intended for _________.

A.parents with young daughters
B.girls who like reading fairy stories
C.girls who think they can change their partners
D.parents with grown-up daughters
【小題2】Cinderella, Rapunzel and Beauty in Beauty and the Beast are similar in that _________.
A.They all married some princes
B.They all changed their partners with love
C.They were all abused by their partners
D.They all put up with abuse
【小題3】Which of the following statements is true of the women in a control group?
A.They don’t believe in fairy tales.
B.They don’t believe in the transformational qualities of love.
C.They have also experienced abuse.
D.They survived abuse.
【小題4】What does the underlined word “submissive”in the 3rd paragraph probably mean?
A.kind-hearted B.passive C.gentle D.easy-going
