Houston, Texas (June 8. 2002)–in 2004, the National Aeronautics and Space Administration (NASA) will send two robots to separate places of Mars to seek out past or present signs of water. It is an exciting idea to send two robots driving over very different places of Mars at the same time, to be able to see what is on the other side of the hill.
Last month, NASA announced it was sending one robot to Mars, but after two weeks, it decided there was enough money for two. The robots will be sent up within two weeks of each other in May and June of 2003 from Kennedy Space Center. If all goes well, the two spacecraft will touch down on Mars, after a seven-and –a-half-month space flight, on January 2 and 20, 2004.
The robots, each weighing 150 kilograms, can cover 100 meters per day. They are designed to be able to examine the mineral content of the soil, and their special camera will take pictures of the lands and hills. Although they will be under control from the earth, the robots are able to move more freely compared to those sent up before them.
The actual landing points have not been determined yet, but the scientists say it will be in areas where they hope to find water.
49.According to the news report, scientists plan to send robots up to Mars to _____.
A.find out whether there is water on Mars B.see if robots can find minerals there
C.test how fast robots can drive there D.prove that robots can work on Mars

Can you remember the day when you spoke your first word? If you can, you are unusual. Try to imagine what first few months of your life were like. I am sure you just spent most of your time eating, sleeping and crying. As you grow older, you were awake more of the time. It took your parents more time to play with you and talk to you. You watched and listened curiously. You began to know that people made certain sounds to go with certain things.
Then you began to try making the sounds you heard. And step by step you were able to make the right sound for one thing.On that day you came to understand the secret of language. The secret is that a certain sound means a certain thing. One sound might be as good as another. But it is no good as a word unless everybody agrees on its meaning. Only when a group of people use the same set of sounds of things, can they understand each other. Then, and only then do these people have a LANGUAGE.
After you found the secret of language, you learned words. Some of the words meant things, such as BOOKS, CHAIRS and SHOES. Some words meant doing things, such as GO and SWIM. And other words describe things, such as GOOD and DIRTY. Soon you learned to put words together to express one’s idea, such as “I want to go out and play with my friends.” This is language. By means of language people can communicate. So we say languages are means of communication. When you were a little baby, you_________.

Happiness is for everyone. You don’t need to care about those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and a lot of money and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads in their free time.
In fact, happiness is always around you if you put your heart into it. When you are in trouble at school, your friends will help you; when you study hard at your lessons, your parents are always taking good care of your life and your health; when you get a success, your friends will say congratulations to you; when you do something wrong, people around you will help you to correct it. And when you do something good to others, you will feel happy, too. All these are your happiness. If you notice a bit of them, you can see that happiness is always around you.
Happiness doesn’t mean money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something that can’t be bought with money. When you meet with difficulties, you can say loudly you are very happy, because you have more chances to challenge yourself. As the saying goes, life is like a revolving（旋转的）door. When it closes, it also opens. If you take every chance you get, you can be a happy and lucky person.When you do something wrong, people around you will_______.

For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict（冲突）between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?
Both sides want peace, but neither feels it has any power to stop the conflict. In part，this is because neither is willing to admit any responsibility for starting it. From the parents’ point of view, the only cause of their fight is their adolescents’ （青少年）complete unreasonableness. And of course, the teens see it in exactly the same way, except oppositely. Both feel trapped.
In this article, I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrel on unimportant things. Examples include the color of the teen’s hair, the cleanness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right. It doesn’t matter what the topic is—politics, the laws of physics, or the proper way to break an egg—the point of these arguments is to prove that you are right and the other person is wrong，for both wish to be considered an authority—someone who actually knows something—and therefore to command respect. Unfortunately, as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progress. Why does the author compare the parent teen war to a border conflict?
| A．Both can continue for generations. | B．Both are about where to draw the line. |
| C．Neither has any clear winner. | D．Neither can be put to an end. |
What does the underlined part in Paragraph 2 mean?
| A．The teens blame their parents for starting the conflict. |
| B．The teens agree with their parents on the cause of the conflict. |
| C．The teens accuse their parents of misleading them. |
| D．The teens tend to have a full understanding of their parents. |
Parents and teens want to be right because they want to__________.
| A．give orders to the other | B．know more than the other |
| C．gain respect from the other | D．get the other to behave properly |
What will the author most probably discuss in the paragraph that follows?
| A．Causes for the parent-teen conflicts | B．Examples of the parent-teen war |
| C．Solutions for the parent-teen problems | D．Future of the parent-teen relationship |
