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（收养）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.

举一反三
Down-to-earth people could be important members of society. But they do not consider themselves to be better than others who are less important. A person who is filed with his own importance and pride is said to have his nose in the air.
Americans use another expression that is similar in some ways to down to earth. The expression is both feet on the ground. Someone with both feet on the ground is a person with a good understanding of reality（现实）. He may have dreams, but he does not allow them to have influence on his understanding of what is real.
The opposite kind of person is one who has his head in the clouds. Someone with his head in the clouds is a person whose mind is not on what is happening in real life. Such a person may be called a day－dreamer.
When we have both our feet on the ground, and when we are down to earth, we do not have our noses in the air. We act honestly and openly to others. Our lives are like the ground below us— solid(牢固的) and strong.
小题1:A down-to-earth person could be_____________.
| A．social and proud | B．good and opposite | C．real and important | D．strong and changeable |

| A．the use of some expressions | B．dreams and achievements |
| C．the lifestyle of honest people | D．honesty and understanding |
| A．get along with other people easily | B．learn from those who are down to earth |

In my spoken English class, I asked the students about their university life. To my surprise, 小题1:. After their highly controlled(控制) high school lives, they were having difficulty getting used to (习惯) the free time in the university. When I asked them to describe their high school lives, 小题2:they got up at six in the morning and studied until ten or even later at night. Most of this time was spent doing lots of homework.
When they entered the university, in my opinion,小题3:to spend all their waking hours studying. They should also take an active part in social activities. They should learn to divide their time outside of class between sport sand clubs. What’s more, 小题4:watching TV and chatting with their roommates. But what surprised me most was that many of them did not seem happy because小题5:. They felt that they should be doing something else what ever they were doing. That’s why they were not happy.
To those students, my advice is: Get used to it and learn to make decisions for yourselves.

The moon moves around the earth. It makes one trip in about four weeks. The moon looks flat to us. But it is a round ball, like the earth.
People once thought the moon had fire on it. They thought the fire made it bright. Now we know the moon is like a mirror. It gets its light from the sun.
Our sunlight comes from the sun, too. What is the sun? The sun is a star. The stars we can see have their own light. There are many big stars we cannot see. Their light had burned out. Others are still bright, but they are so far away that we cannot see them. The sun looks bigger and much brighter than other stars because it is the nearest of all stars. The sun and the other stars we see are very hot, but the air around us saves us from the heat of the sun.
The sun gives us light and warmth. It makes plants grow and turns leaves green. It makes life possible on our earth. It is a life giving star.

Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into his shell. A snail will die in a heavy rain. So when it rains, a snail does the same thing, too. A snail can sleep for as long as it needs to. It spends all the winter months in its shell, asleep.
In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers (触角), are very weak. But its sense (感觉) of smell is very strong. It helps the snail to find food and the new greens.
A snail’s mouth is no bigger than the point of a pin (大头针). Yet it has 256,000 teeth! The teeth are very small, and you can’t see them. If you put a snail in a hard paper box, it will eat its way out! And if a snail wears out its teeth, it will grow new ones.
