For years scientists have been arguing about whether nature or nurture (后天) decides what people will be like. Is it nature— what people are (41) with— that decides what they will be like? (42) is it nurture —what(43) to people when they are born —that decides what they will be like?
Scientists have been studying twins to (44) if they can find the answer, because twins start out with the (45) DNA. Sometimes twins don’t live together at birth and grow up in different (46) and different places— so the nature is the same for both, but the nurture is different.
When scientists (47) these twins in their later life, they some times find some surprising (48).
Jim Springer and Jim Lewis were adopted（收養(yǎng)）by two different families at birth. They first met each other again thirty-nine years (49) and discovered they had a lot in (50). Both had been (51) twice. Their first wives were both named Linda and their second wives were both named Betty!
Each twin had a son — one called his son James Alan and the (52) called his son James Alan, too. Their children each had a dog called “Toy”. They even arrived at their first (53) in the same color of car.
So far twin (54) seem to show that both nature and nurture are important. What we have from birth, and how and where we live help to build (55) we are.

Every day when I enter the classroom, I will take a look at the wall beside my seat. You will find nothing special about this old wall if you just look at it. But for the students in my class, it is a special wall. Take a good look at it, and you will get to know the real feelings and thoughts of us, the 9th graders.

In the middle of the wall, there is a big “VICTORY”. It was written in pencil. I guess it must have been written by someone who got a good mark in an exam.

A little higher above the formulas, there is a poem. It only has two sentences. It reads: All those sweet memories have disappeared. Like tears dropping in the heavy rain.

Oh! It must have been written at the end of the last semester in middle school. Classmates had to leave school and good friends had to part. What a sad poem!

If you look at the wall more carefully, you will find many other interesting things, like a crying face, or a happy face, and other patterns(圖案). There are still some patterns and letters that I can’t understand, but they all show the feeling of the students who drew them.

For years, the wall has witnessed(目睹) all the things that have happened in the classroom. I don’t know how it will be next year, two years from now, or even ten years from now. But I hope more smiling faces will be drawn on it.

1.There is ____ special on this wall.

A．something

B．a(chǎn)nything

C．nothing

D．everything

2.What was the “VICTORY” written in?

A．Chalk

B．Pencil

C．Pen

D．Brush

3.When has the poem been written?

A．At the beginning of the last semester.

B．At the end of the year.

C．At the end of the last semester.

D．At the beginning of the last month.

4.What’s the meaning of the underlined word?

D．聚集

5.What’s the title of the passage?

My uncle has a very beautiful umbrella. He's had it for years. As he is very careful with it, so it still looks as good as new.   1   He shook his head. "Then how did you get it?" I asked. "Well," he answered, "there' s a strange true story about the umbrella. About ten years ago, I was walking along a quiet London street one evening when it suddenly rained. I had no raincoat or umbrella.   2   And the people in the streets were fewer and fewer. As I was on my way to a party, I was afraid to get wet. So I stood in a doorway and waited for the rain to stop.   3   What was worse, there even wasn't a person around, and still it rained and rained. At last a young man came to the place where I was standing.   4   As I hoped he would allow me to walk to the next corner with him, where I could get a taxi, I stepped out of the dark doorway where I had been standing.   5    As I suddenly appeared before him, the young man was so shocked that he dropped the umbrella. He ran away and disappeared into the darkness. I picked up the umbrella and continued my walk. I knew it would be hard in this big city to find the owner, so I've kept it ever since."

B. He held a large umbrella over his head.

C. I asked him where he was going with that umbrella.

D. No buses ran through the street and there were no taxis.
