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.
1.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
2.How long in between will the two robots be sent to Mars?
A.1 year B. 7.5 months C. 2 months D. 2 weeks
3. One of the important jobs for the robots on Mars is to _______.
A.study the soil B. walk everywhere
C.test the new camera D. find a suitable landing point
4. We can infer from the last sentence that scientists ________.
A. have changed the landing points many times
B. hope to land the robots on the surface of water
C. are still working on the plan
D. know where they can find water

I believe that families are not only blood relatives, but sometimes people who show up and love you when no one else will.
In May 1977, I was living in a Howard Johnson’s motel off Interstate 10 in Houston. My dad and I 1 a room with two double beds and the bathroom was too 2 for a 15-year-old girl and her father.

A new study has been carried to test the role of story telling in lowering blood pressure. Dr. Thomas Houston, a professor of the University of Massachusetts Medical School, led a group of scientists that researched how pre-recorded videos of hypertension (高血压) patients' talking about their medical histories helped another group of patients with high blood pressure to control their condition over several months.
Houston was surprised by their studies that suggested that communication can be a powerful tool in medicine. They showed that those who had had similar experiences, when talking to someone with a similar background, could help change their behavior to become healthier. Hypertension is difficult to control, since it is dependent on diet, exercise and mental state. Medical treatments with drugs, and lifestyle therapies(疗法) have been relatively ineffective because people find it hard to follow those medical requirements.
In the test, his team carefully chose their story-tellers from 23
0 members of a patients' community with whom they could most easily relate. Next, they divided their study population into two groups. One received three interactive DVDs containing the tellers' stories of their experiences in living with and treating their hypertension. The other were given educational discs on an unrelated health topic. The study volunteers reported that they had listened to the DVDs, and after three months, those who heard the stories of the hypertensive patients lowered their blood pressure.
While the study did not address how the story-telling influenced the patients' behavior, Houston doubts that watching patients of similar backgrounds who had a similar medical experience helped to motivate them to seek medical help to their hypertension. They found that after six months the difference in blood pressure between those who watched the story-tellers and those who observed the unrelated videos remained, suggesting that the story-telling continued to have an effect.

| A．tell medical histories of hypertension patients |

| D．people don't follow the medical requirements |
| A．persuade | B．observe | C．attend | D．announce |
| A．The stories of some hypertension patients. |
| B．Medical treatments of blood pressure. |
| C．Storytelling may help lower blood pressure. |
