Think stars don’t move? Think again! When you look at the sky at night, the stars may appear to stay in the same place. But stars are always on the move—they are just so far away that the movement is hard to see.
But some stars move in ways that appear to be strange to be real. In 2005, astronomer Warren Brown found one of these space oddities(奇特). It was located on the outer edge of the Milky Way, the galaxy(星系) we live in. The star was speeding away like nothing he’d ever seen. “It seemed unbelievable. No star in the galaxy has a speed like that,” Brown remembers. “I thought, oh my goodness, I have something kind of special here.”
No one had ever seen a star like this one. What does a scientist do when the results don’t make sense?
Brown didn’t give up. Instead, he kept looking. And he kept finding more of these strange and speedy stars, called hypervelocity stars. Hyper means “above” and velocity has to do with speed. He and his team just found six more of these “above speed” stars, bringing to the total of 16. And, he says, he’s found even more, and is just waiting for the scientific community to confirm them.In 2005, astronomer Warren Brown found___________.

Twenty years ago, I drove a taxi for a living. One night I went to pick up a passenger at 2:30 AM. When I arrived there, I walked to the door and knocked, “Just a minute,” answered a weak, elderly voice.
After a long pause, the door opened. A small woman in her eighties stood before me. By her side was a small suitcase.
When we got into the taxi, she gave me an address, and then asked, “Could you drive through downtown?”
“It’s not the shortest way,” I answered quickly.
“Oh, I’m in no hurry,” she said. “I’m on my way to a hospice(临终医院). I don’t have any family left. The doctor says I don’t have very long.”
I quietly reached over and shut off the meter(计价器).
For the next two hours, we drove through the city. She showed me the building where she had once worked, the neighborhood where she had lived, and the furniture(家具) shop that had once been ，a ballroom where she had gone dancing as a girl.
Sometimes she’d ask me to slow down in front of a special building and would sit staring into the darkness, saying nothing.
In the early morning, she suddenly said,” I’m tired. Let’s go now.”
We drove in silence to the address she had given me.
“How much do I pay you?” she asked.
“Nothing.” I said.
“You have to make a living,” she answered. “Oh, there are other passengers,” I answered.
Almost without thinking, I gave her a hug(拥抱). She held on me and said, “You gave an old woman a little moment of joy.”The old woman chose to ride through the city in order to ______.
| A．show she was familiar with the city |

A teacher stood in front of his history class of twenty students just before handing out(分发) the final exam.

There is an old saying in English, “Laughter is the best medicine”. Until recently, few people took the saying very seriously. Now however, doctors have begun to study laughter and the effects (作用) it has on the human body. They have found evidence(证据) that laughter really can improve people’s health.
Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart rate, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, the heart rate（率） and the rate of breathing. It also works several groups of muscles（肌肉） in the face, the stomach and even the feet. If laughter exercises the body, it must be helpful.
Other tests have shown that laughter appears to make the effect of pain on the body less. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group which could bear the pain for the longest time was the group which listened to a funny program. The reason why laughter can make pain less seems to be that it helps to produce endorphins (内啡肽) in the brain. These are natural chemicals which make both stress and pain less.
There is also some evidence to suggest that laughter helps the body’s immune(免疫) system that is the system which fights infection (感染). In an experiment, one group of students watched a funny video while another group served as the control group — in other words, a group with which to compare the first group. Doctors checked the blood of the students in both groups and found that the people in the group that watched the video had an increase in the activity of their white blood cells that is the cells which fight infection.
As a result of these discoveries, some doctors and psychiatrists (精神病学) in the United States now hold laughter clinics, in which they try to improve their patients’ condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce good effects similar to those caused by laughter.We learn from the first paragraph that laughter________.
| A．is good for one’s health |
