Have you ever had the strange feeling that you were being watched? You turned around and, sure enough, someone was looking right at you!
Parapsychologists (靈學家) say that humans have a natural ability to sense when someone is looking at them. To research whether such a“sixth sense”really exists, Robert Baker, a psychologist (心理學家) at the University of Kentucky, did two experiments.
In the first one, Baker sat behind unknowing people in public places and stared(盯著）at the backs of their heads for 5 to 15 minutes. The subjects（受試者）were eating, drinking, reading, studying, watching TV, or working at a computer. Baker made sure that the people could not tell that he was sitting behind them during those periods. Later, when he questioned the subjects, almost all of them said they had no sense that someone was staring at them.
For the second experiment, Baker told the subjects that they would be stared at from time to time from behind in a laboratory setting. The people had to write down when they felt they were being stared at and when they weren’t. Baker found that the subjects were no better at telling when they were stared at and when they weren’t.
Baker concludes that people do not have the ability to sense when they’re being stared at. If people doubt the outcome of his two experiments, said Baker,“I suggest they repeat the experiments and see for themselves.”
小題1:The aim of the two experiments is to ________.
A．explain when people can have a sixth sense
B．study how people act while being watched in the lab
C．study whether humans can sense when they are stared at
D．prove why humans have a sixth sense
小題2:The underlined word “outcome” in the last paragraph most probably means ________.

小題3:In the second experiment, the subjects _________.
A．could tell when they were stared at
B．could tell where they weren’t stared at
C．couldn’t tell who they were stared at or who they stared at
D．couldn’t tell when they were stared at or when they weren’t
小題4:What can be learned from the passage?
A．People are born with a sixth sense.
B．The experiments support parapsychologists’ idea.
C．The subjects do not have a sixth sense in the experiments.
D．People have a sixth sense in all places.

Aunt Polly had told Tom to paint the whole fence (柵欄)in front of the house. He thought of the other boys out for the day enjoying themselves and he felt very unhappy. Then he had an idea! He picked up the brush and started painting slowly and carefully. Soon, his friend Ben Rogers appeared, eating an apple. Tom pretended (假裝) not to see him.
“Tom!” Ben said. “Why are you working?”
“Oh, it’s you, Ben,”Tom said, “I didn’t notice you.”
“I’m gong for a swim,” Ben said, “but you don’t’ want to come. You want to work, don’t you? It’s much nicer!” Ben laughed loudly. Tom looked seriously at Ben and said. “What is work? What do you call work?”
“Isn’t that work?” Ben asked.
“Well, no. Does a boy get the opportunity to paint a fence every day? You’ve never painted a fence, have you? Auntie says I have to do it with great care!’
“Pleas, Tom. Let me do a little,” said Ben.
“No, Ben. If you do, you’ll do it wrong. You can’t paint very well. If it was the back fence wouldn’t mind, but it isn’t.”

The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly held image of unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes (態(tài)度) surprisingly shows that their family life is happier than it has ever been in the past. “We were surprised by just how positive (積極的) today’s young people seem to be about their families,” said one member of the research team. “They’re expected to be rebellious（叛逆的）and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There’s discussion between parents and children, and children expect to take part in the family decision-making process. They don’t want to rock the boat.”
So it seems that these parents are much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me,” says 17-year-old Daniel LaSalle. “I always tell them when I’m going out clubbing. When they know what I’m doing, they’re fine with it.” Susan Cromer, who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call talk or discussion. For example, when I’d done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion（叛逆）is not based on real facts. A researcher explains, “Teenagers were thought to be different from others in a part of time in our social history. But to our surprise, they say they are getting on well with their parents. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled.”
小題1:The study shows that teenagers don’t want to ______________________.
A．share family dutiesB．cause trouble in their families
C．go boating with their familyD．make family decisions
小題2:Compared with parents of 30 years ago, today’s parents ___________________.
A．go to clubs more often with their childrenB．are much stricter with their children
C．care less about their children’s lifeD．give their children more freedom
小題3:According to the writer, teenage rebellion ____________________.
A．may be a wrong opinionB．is common at present
C．lived only in the 1960sD．was caused by changes in families
小題4:Which title best gives the main idea of the passage?
A．Discussion in family.B．Teenage education in family.
C．Harmony in family.D．Teenage trouble in family.

“Who did this?” asked my teacher. Thirty children tried to think about not only what they had done, but also what our teacher might have found out.
“Who did this?” she asked again. She never became angry, but she was this time. She held up a piece of broken glass and asked, “Who broke this window?”
“Oh, oh,” I thought. I was the one who broke the window. I did not do it on purpose (故意). It was caused by a bad throw of a baseball. Why did it have to be me?
If I admitted (承認) it, I would be in a lot of trouble. How would I be able to pay for a big window like that? “My father is going to get angry at me,” I thought. I didn’t want to raise (舉起) my hand, but something much stronger than me pulled it up.
“I did it,” I said. Then I was silent. It was hard enough saying what I had.
My teacher went to one of our bookshelves and took down a book. She then began walking towards my desk. I had never known my teacher to strike (打) a student, but I feared she was going to start with me.
“I know how you like birds,” she said as she stood looking down at my face. “Here is the field guide about birds (鳥類野外指南) that you always check out from our school library. It is yours now. We have got a new one for the school. You will not be punished (懲罰). But remember, it’s only for your honesty.”
I couldn’t believe it! I wasn’t being punished and I was getting my own bird field guide, the one that I had been saving up all my money to buy.
小題1:How did the writer feel when he saw his teacher walking towards him with a book from bookshelves?

請閱讀下面這篇文章，完成下面表格。
I am Jay from Zhuhai Sunshine Middle School. Recently, we carried out a survey on who we prefer to share worries with. We got different answers.
　　 Acording to the chart, those who would like to share their worries with their classmates and friends account for about 71%. It is mainly because they believe that if people are at the same age, they are easy to communicate and understand each other better.
　　About 22% of the students said they would like to share worries with their teachers and parents. According to them, adults are rich in experience, and that they can handle their problems easily. The rest prefer to keep worries to themselves. As for them, it’s a struggle to get along well with others, some of them said they didn’t want to trust anyone.
　　As far as I am concerned, I am willing to share worries with my best friends because they’re always kind and understanding. However, if I meet with some serious problems, I’ll be likely to ask my parents and teachers for help, who, I believe, have more experience to give me valuable advice.

After my husband died, my world crashed around me. My six children were ten, nine, eight, six, three and 18 months, and I was overwhelmed(不知所措的) with the responsibilities of earning a living, caring for the children and simply keeping my head above water.
I was lucky to find a wonderful housekeeper to care for the children during the week, but from Friday nights to Monday mornings, the children and I were alone, and frankly(坦誠地) I was uneasy. Every unusual noise or any late-night phone call filled me with fear. I felt really alone.
One Friday evening I came home from work to find a big beautiful German shepherd(牧羊犬) on our doorstep. It was obvious he wanted to make the house his home. The children took an instant liking to “German” and asked me to let him in. I agreed to let him sleep in the basement(地下室) until the next day. That night I slept peacefully for the first time in many weeks.
The following morning we made phone calls and checked lost-and-found ads for German’s owner, but with no results. Saturday night he was still with us. 
On Sunday I had planned to take the children on a picnic. Since I thought it best to leave German behind in case(以免) his owner came by, we drove off without him. When we stopped to get gas at a local station, we were amazed to see German racing to the gas station after us. He stayed again Sunday night.  
Monday morning I let him out for a run while the children got ready for school. He didn’t come back. We thought we’d never see him again. On Friday evening, German was back again. We took him in, and again he stayed until Monday morning, when our housekeeper arrived. It went like this for almost 10 months. We looked forward to his coming. Each Monday morning he left home.
Each week, between German's visits, I grew a little braver, but every weekend I enjoyed being with him . Then one Monday morning we patted his head and let him out for what turned out to be the last time. He never came back. We never saw or heard from German again. I think of him often. He came when I needed him the most and stayed until I was strong enough to go on alone. I believe German was sent because he was needed, and because no matter how abandoned(被放棄的) and alone we feel, somehow, somewhere, someone knows and cares. We are never really alone.
小題1:What does the underlined part “keeping my head above water” in the first paragraph mean?
