【題目】
We do everything we can to hide from the sun in summer. Some wear hats, others buy umbrellas or sit under trees. But can you imagine what it would be like to have two suns over your head?
Well, the Kepler-47 system does have two stars in its sky, according to a discovery in the Science Journal.
The new system was found by NASA’s Kepler space telescope. It is about 5,000 light-years away from us. One of the stars is similar to our sun, but the other is much smaller and less than 1 percent as bright.
In fact, systems with two stars are quite common. “Unlike our sun, many stars are part of multiple-star(多個恒星的) systems. There, two or more stars circle each other,” said a scientist from NASA’s Research Center in the US.
Scientists are more surprised that there could be two planets in the Kepler-47 system because it is very hard for planets to form in such a complex environment.
One of the planets, Kepler-47b, is closer to the stars. It’s three times larger than Earth. The other one, Kepler-47c, is about 4.5 times the size of Earth. Most importantly, Kepler-47c is neither too close nor too far away from the stars. It means the planet won’t be too hot or cold. So scientists believe there could be water on it or even life.
【1】Which of the ways is NOT mentioned in the passage for people to hide from the sun?
A.Wearing hatsB.Wearing sunglassesC.Buying umbrellasD.Sitting under trees
【2】According to Paragraph 3 and 4, the two stars in the Kepler-46 system_______.
A.are similar to our sun in sizeB.always move around each other
C.are quite unusual to exist(存在) togetherD.belong to another multiple-star system as well
【3】What does the word “complex” in Paragraph 5 mean?
A.不尋常的B.單一的C.艱難的D.困惑的
【4】Which is TRUE about the planets in the Kepler-47 system?
A.Kepler-47c is neither too hot nor too cold.
B.Kepler-47c is proved to be suitable for lives.
C.Kepler-47b is 4.5 times as large as the Earth.
D.Kepler-47b is farther away from the stars than Kepler-47c.
【5】The passage mainly talks about __________.
A.the newly-found Kepler-47 systemB.the stars and planets of multiple-star system
C.the information of different systems in spaceD.the special environment of our solar system

【題目】
A recent study suggests that teenagers who turn off the TV and sit down to family meals are less likely to suffer eating disorders. The study has connected eating together with lower rates of bulimia and anorexia. The meanings of bulimia and anorexia are eating too much, or eating at wrong times too often or eating very little. Besides, the study shows that teens who are used to eating round the table are less likely to take up smoking to lose weight.
Researcher Barbara said, “In many people’s opinion, teenagers don’t want to be around their parents very much, and they are too busy with their studies and spend more time with their friends.”
The study shows happy families have teenagers who eat with their parents often. These teens have less bad diet or dangerous eating habits. “For most parents, it is difficult to get their families together around the table seven days a week. But if they can prepare three family meals a week,it will be good for their children’s health,” Professor Fiese spoke out after reviewing 17 studies on eating ways and nutrition of almost 200,000 children and teenagers. She has found that teens who eat at least five meals a week with their families are 35% less likely to be “disordered eaters”. Even three family meals a week helped, with youngsters 12% less likely to be overweight than those who ate with their families less often. They were also 24% more likely to eat healthy foods and have healthy eating habits than those who didn’t share three meals with their families.
“Teens can also use family meals as a time to get their thoughts across,” Professor Fiese said, “Family meals give them a place where they can go regularly to check in with their parents and express themselves freely.”
【1】Which of the following is NOT a reason why children don’t eat with their parents?
A.They are too busy with their studies.B.They think their parents are too strict.
C.They spend a lot of time with friends.D.They don’t want to be with their parents too often.
【2】What advantage of the family meals is mentioned in the last paragraph?
A.Teens can form good eating habit.
B.Teens can ask their parents for advice.
C.Teens can come up with some good ideas.
D.Teens can express their thoughts to their parents.
【3】What can we learn from the passage?
A.Parents will have meals on time if they eat with their children.
B.Teenagers who often have meals with their parents are cleverer.
C.It is good for family members to watch TV while having meals.
D.Teenagers have good eating habits because they usually have meals with their parents.
【4】What does the author want to tell us in the article?

【題目】
At 26, Jane Goodall had no college education or science training. But since childhood, she had been dreaming of working closely with animals in Africa. “All through my childhood people said, ‘You can’t go to Africa. You’re a girl.’ ” Jane said. “ But my mother used to say, ‘If you really want to, there’s nothing you can’t do.’ ”
In 1957, 26yearold Goodall went to Kenya to work as a secretary. She met the famous scientist Louis Leakey, who was so impressed by her hard work that he made her as his assistant. She went with him on many trips to the African forest and in 1960 Leakey sent Goodall to live among chimpanzees* in a protection zone, recording the animals’ behavior and interactions.
For three months Goodall made little progress. But she said, “I never came close to giving up.” Her breakthrough came one day when she saw a male chimpanzee stick a piece of grass into an ant hill, then put the grass in his mouth. Afterward she came to the hill and did the same. Pulling the grass out, she discovered lots of ants on it. The discovery—that some animals use tools—was unknown to most scientists at the time.
Goodall saw chimpanzees show human-like feelings, such as anger and love. But she also discovered they were able to attack* against each other.
Goodall received her Ph.D. in the study of animal behavior at England’s Cambridge University. Now she travels around the globe raising money to protect wildlife. “I love being in the forest with the chimpanzees,” she said. “ I’d rather be there than travel around from city to city.”
【1】What did Goodall’s mother think of her dream?
A.As a girl she should not go to the African forest.
B.As a girl she should stay away from dangerous animals.
C.She could make her dream come true if she made up her mind.
D.Her dream would remain a dream unless she got the right training.
【2】What does the underlined word “breakthrough” mean in the third paragraph?
A.progressB.studyC.storyD.work
【3】What’s Jane Goodall’s most important discovery?
A.Some animals use tools.
B.Ants are chimpanzees’ favorite food.
C.Like humans, animals have feelings.
D.Chimpanzees could attack each other strongly.
【4】According to the passage, which of the following is TRUE?
A.Jane Goodall is working hard for a Ph.D. degree now.
B.Jane Goodall is raising money for the protection of wildlife now.
C.Jane Goodall is recording chimpanzees’ behavior in African forest now.
D.Jane Goodall is studying animal behavior in Cambridge University now.
