What will the car be like in the future? Maybe we can sit in a car that can drive itself.
About 40 years ago, scientists from the United States started to develop self-driving cars (無人駕駛汽車). The most famous recent one was made by Google in 2009. There are cameras and radars (雷達) on the top of the car. They allow the computer in the car to draw a 3D map of the environment. Chinese scientists have also successfully developed a self-driving car. The car made a trip from Changsha to Wuhan.
Is a self-driving car safe? A recent study shows that robots make safer drivers than humans. If only 10% of cars on the street are self-driving, they will save 1,000 lives (生命) every year. If 90% of vehicles (交通工具) are self-driving, 21,700 lives will be saved a year. However, a self-driving car is expensive and each costs about $100,000. So it is impossible to be very popular in the near future.

小題1:American scientists started to develop self-driving cars in 2009.
小題2:Cameras and computers are on the top of the self-driving car by Google.

I won’t forget her advice
I had a very special teacher in high school many years ago. Her husband died of a heart attack. About a week after his death, she shared some of her insights（見解）with us.
The class was nearly over. She said, “Before class is over, I would like to share with all of you an important thought.”
“Each of us is put here on Earth to learn, share, love, enjoy and give all by ourselves. We must make the best of every single day.”
Her eyes were beginning to water and she went on, “So I would like you all to make me a promise. From now on, on your way to school, or on your way home, find something beautiful to notice. It doesn’t have to be something you see — it could be a nice smell — perhaps of freshly baked bread, or it could be the sound of the breeze slightly blowing the leaves in the trees.”
“Please look for these things, and love them. For, although it may seem common, these things are the stuff（素材）of life. They are the little things we are put here on Earth to enjoy. They are the things we often take for granted. We must make it a point to notice them, for at any time it can all be taken away.”
The class was completely quiet. We picked up our books and went out of the room silently. That afternoon, I noticed more things on my way home from school than I had that whole term.
I usually think of that teacher and try to enjoy all of those things that we sometimes overlook (忽略).
Take notice of something special you see during your lunch hour today. Walk barefoot along the beach at sunset. For as we get older, it is not the things we did that we regret（后悔）, but the things we didn’t do.

A boy called Mario had many friends, and he was proud of it. Whoever he met, he would like to show off(炫耀) how popular he was at school.
One day, his grandpa said to him, “Mario, I know that you don’t have as many friends as you think. Many of them are not true to you.”
Mario thought maybe his grandpa was right. However, he wasn’t sure how he could test whether his schoolmates were real friends or not, so he asked his grandpa. The old man answered, “I have just exactly what you need. It’s in my room.

Mario took the strange invisible chair to school. At break time he asked everyone to form a circle, and he put himself in the middle, with his chair.
“Nobody move. You’re about to see something amazing，” said Mario. Then he tried sitting on the chair. Having difficulty seeing it, he missed and fell to the ground. Everyone had a pretty good laugh. “Wait, wait,” said Mario, making another try. But again he missed the seat.
Mario didn’t give up. He kept trying to sit on the magic chair. Finally, he did it. This time he felt himself in mid-air.

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 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 and the rate of breathing. It also works several groups of muscles 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 (內(nèi)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 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 (精神病學(xué)) 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.
小題1: We learn from the first paragraph that laughter           .
A．is good for one’s health
B．has strong effects to do with some illness
C．has been studied long since
D．has no effect on the body
小題2: Doctors have found that laughter           .
A．keeps down blood pressure
B．has similar effects to physical exercise
C．decreases the heart rate

小題3:Which of the following statements is NOT true of laughter according to the passage?
A．It makes pain less.
B．It exercises the body.
C．It improves the body’s immune system.
D．It can cure cancer.
小題4: Smiling can produce _________.
A．a(chǎn)bout the same effects as laughter
B．more effects than laughter
C．fewer effects on the human body
D．no effects on the human body
小題5: The main idea of this passage is that _________.

C．tests show that laughter can produce positive effects on human body
D．laughter and physical exercise have the same effects on human body

You may not have heard the words “freshman fifteen” before, but they are very important for students who are entering university(大學(xué)). A freshman is a first-year college student. “Fifteen” means fifteen pounds---the fifteen pounds added to a student’s weight in his or her first year. There are a number of reasons why first-year university students gain(增加) weight; but it’s encouraging to know that freshmen don’t have to add these harmful fifteen pounds.
Mistakes choosing food
University kitchens serve(供應(yīng)) many kinds of food. Some students choose unhealthy food, because now their patents are not nearby to help them choose. Some students visit the kitchen many times while studying. Late at night, some students get harmful fast food such as fish and chips with Coke to drink. Students also have less time for walking, running, and doing sports because of their schoolwork.
Eating right
If you’re careful, you don’t have to add fifteen pounds. Here are some ideas:
Think more about what you eat.
Eat plenty of vegetables and healthy meats.
Don’t eat desserts full of sugar; have fruit after dinner.
Try not to eat so much unhealthy food while you study.
It’s all right to have a little fast food sometimes---but not often.
Write down the foods you eat.
Walk, run, do sports---move and you will feel better!
Remember that the “freshman fifteen” can happen to anyone. Talk to your friends about it. Together, try to eat healthy food and not to eat unhealthy food. Walking, running, and playing sports is always more fun with friends. Help each other and you can have a healthy and happy freshman year.
小題1:The “freshman fifteen” is _______.
A．weight that high school students gain
B．weight that first-year university students can gain
C．fifteen pounds of food that first-year students eat
D．fifteen students who eat unhealthy food
