Scientists are placing robotic dogs in the homes of lonely old people to test whether they can improve the quality of life for humans. Alan Beck, an expert(專家) in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study on the effect of robotic dogs on old people’s depression (沮喪) , physical activity, and life satisfaction.
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, scientists will collect baseline data(數據) for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the scientists will review the data to test if it has produced any changes in the life of its owner.
“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady. “When I’m watching TV, he’ll stay in my arms until he wants down. He has his own mind.”
The AIBOs respond to certain orders. The scientists say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate(與……相關) to the robotic dog, because it was metal and not furry.” Beck says. “Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters’ blood pressure, oxygen levels or heart rhythms(心律). AIBOs may even one day have games that can help stimulate(刺激) older people’s minds.”
小題1:The purpose of Beck and Edwards’ study is to _____________.
A.understand human-animal relationship
B.make lonely old people’s life better
C.find the causes of old people’s loneliness
D.improve the animal-assisted research
小題2: In the research, the old people are asked to _____________.
A.note the activities of AIBOs
B.keep AIBOs at home for 12 weeks
C.record their feelings and activity
D.study the collected information
小題3:What does the underlined word “removes” mean?
A.moves againB.is movableC.doesn’t needD.need
小題4:What is the better point of AIBO than live dogs?
A.It is easier to keep at home.
B.It can help the disabled people.
C.It responds to all the human orders.
D.It can watch TV with its owner.
小題5:The writer seems to suggest that the future robotic dogs may__________.
A.cure certain diseasesB.keep old people active
C.change people’s ideasD.look more like real dogs

German scientists say that eating a little chocolate every day may keep you away from cardiovascular(心血管的) disease. The scientists have found that chocolate, especially dark chocolate , can help you cut down 39 percent of heart disease, including taking a very small amount . However, the study advises people not to eat too much chocolate, because too much chocolate is bad for our bodies. So the scientists advise people to eat small amount of chocolate instead of sugar or high-fat snacks.
Scientists said, “Dark chocolate shows the greatest effects, milk chocolate fewer , and white chocolate no effects.” The results showed chocolate may cut down blood pressure, but they also say that further study is needed.
In the eight-year study, people’s daily diet, exercise habits, and blood pressure were studied in 19,357 persons aged 35 to 65. They found that people who are an average of 7.5 grams of chocolate a day had a very lower chance of heart disease than those who ate much less chocolate , and average of 1.7 grams a day.
小題1:It took the scientists __________ years to prove that small amount of chocolate is good for people.
A.8B.35C.39D.65
小題2:In the study, scientists studied _______________.
A.where chocolate came from

The teacher stood before his class of 30 students and was going to hand out the final exam papers. “I know how hard you have all worked to get ready for this test. ” he said. “And because I know you are all able to understand these questions. I am ready to offer a B to anyone who would prefer not to take the test. ’’
A number of students jumped up to thank the teacher and left the classroom. The teacher looked at the rest students and said. “Does anyone else want to get a B? This is your last chance. ”Two more students decided to go. Seven students stayed. The teacher then handed out the papers. There were only three sentences on the paper: Congratulations! You have received an A in this class. Keep believing in yourself.
I never had a teacher who gave a test like that. but I think that it is a test that any teacher could and should give. Students who do not have confidence in what they have learned are B students at most.
The same is true for students in real life. The A students are those who believe in what they are doing because they have learned from both successes and failures. They have learned life’s lessons. whether from school education or from events in their lives,and have become better people. Scientists say that by the age of eight,80% of what we believe about ourselves has already been formed. You are a big kid now and you realize that you have some limits(局限). However,there is nothing you can’t do or leant to be. Sir Edmund Hillary, the first person to reach the top of Mount Qomolangma (珠穆朗瑪峰)said,“We do not conquer the mountain, but ourselves. ”
小題1:Some students left the classroom because _________.
A.they were happy with the grade the teacher would give them
B.they were allowed to take another easier exam later on
C.they knew the teacher didn’t like them to take the test
D.they thought the exam was so easy that they don’t need to have a try
小題2:The teacher gave the rest students an A because __________.
A.they answered all the questions in the exam correctly
B.they didn’t believe themselves
C.they believed themselves in what they had learned
D.they had been working hard for each exam
小題3:The underlined word “conquer’’ means __________ in the passage.
A.發現B.控制C.探索D.征服
小題4:What does the writer want to tell us in the passage?

One afternoon I toured an art museum while waiting for my husband to finish a business meeting. I was looking forward to a quiet viewing of the wonderful paintings.
A young couple were viewing the paintings in front of me and chatting with each other without stop. I watched them for a moment and noticed the man’s wife was doing all the talking. I was surprised to see that the man was so patient and could stand his wife’s words, but I still moved on.
I met them several times when I moved through the different rooms of art. Each time I heard she continued talking about the paintings, I moved away quickly.
I was buying some gifts in the museum shop when the couple came near to the gate. Before they left, the man reached into his pocket and pulled out something brown. He turned it into a long stick and then tapped(輕敲) his way into the coatroom to get his wife’s jacket.
“He’s a brave man,” a clerk beside me said. “Most of us would give up if we became blind at such a young age. During his treatment, he made a promise that his life wouldn’t change. So, as before, he and his wife come in whenever there’s a new art show.”
“But what does he get out of the art?” I asked. “He can’t see.”
“Can’t see? You’re wrong. He sees a lot , more than you or I do.” The clerk said, “His wife describes each painting, so he can see it in his head.”
I learned something about patience(耐心), courage and love that day. I saw the patience of a young wife describing paintings to a person who was blind and the courage of a husband who would not allow blindness to make his life different. And I saw the love shared by two people as I watched this couple walk away holding each other’s hands.
根據短文內容填空,每空填一詞。
小題1:When I stayed at the art museum, I ___________ to look at the wonderful paintings without any ___________.
小題2:To my ___________, only the wife kept talking about the paintings all the time while her husband just listened to her ___________.
小題3: I didn’t realize that something was wrong with the young man’s ___________ until I noticed him using a long ___________ to trap his way.
小題4: The man can see each painting in his ___________ because his wife ___________ it to him.
小題5: The young couple not only share a common interest in ___________ but also share their strong ___________.

In front of my daughter, Shelly, was a bowl filled with cabbage. She hated cabbage. She only sat there in silence with tears in her eyes.
“Shelly, my dear, why don’t you eat a little? If not, your mum will shout at us.”
Shelly didn’t feel happy. “OK, dad. I will eat, just a little.” Then Shelly said, “Dad, if I eat it all, will you give me what I want?”
“Yes.”
Slowly she began to eat. It took her almost half an hour to finish all the food in the bowl. Then she came up to me and said, “Dad, I want to have my hair cut off!”
“Shelly, why don’t you ask for something else? If we see your head like that, we’ll feel very sad,” I said.
“But Dad, you promised! Now you’re going back on your words. ”
I had to keep my promise. Shelly had all her hair cut off. She smiled.
