My teenage son Karl became withdrawn after his father died. As a single par ent, I tried to do my best to talk to him. But the more I tried, the more he pulled away. When his report card arrived during his junior year, it said that he had been absent 95 times from class es and had six falling grades for the year. At this r ate he would never graduate. I sent him to the school adviser, and I even begged him. Nothing worked.
One night I felt so powerless that I got down on my knees and pleaded for help. “Please God, I can’t do anything more for my son. I’m at the end of my rope. I’m giving the whole thing up to you.”
I was at work when I got a phone call. A man introduced himself as the headmaster. “I want to talk to you about Karl’s absences.” Before he could say another word, I choked up and all my disappointment and sadness over Karl came pouring out into the ears of this stranger. “I love my son
but I j ust don’t know what to do. I’ve tried everything to get Karl to go back to school and nothi ng has worked. It’s out of my hands. “For a moment there was silence on the other end of the line. The headmaster seriously said, “Thank you for your time”, and hun g up.
Karl’s next report card showed a marked improvement in his grades. Finally, he even made the honor roll. In his fourth year, I attended a parent-teacher meeting with Karl. I noticed that his teachers were astonished at the way he had turned himself around. On our way home, he said, “Mum, remember that call from the headmaster last year?” I nodded. “That was me.

Early in 1980, a magazine called Good Housekeeping printed an amazing article. It was the true story of twins who met for the first time —when they were 39 years old. The twins were separated when they were five weeks old and adopted by different families.
In 1979 they found each other. They found out that they were both named Jim. Although they had never met, they had both been married to women named Linda. Of course, they looked exactly alike. They also walked alike, laughed alike, and even talked alike.

Instead of hitting the beach, fourteen high school students traded swimming suits for lab coats last summer and turned their attention to scientific experiments.
The High School Research Program offers high school students guidance with researchers in Texas A&M’s College of Agriculture and L ife Sciences. Jennifer Funkhouser, academic adviser for the Department of Rangeland Ecology and Management, directs this four-week summer program designed to increase understanding of research and its career potential.
Several considerations go into selecting students, including grades, school involvement and interest in science and agriculture. And many students come from poorer school districts,
Funkhouser says. “This is their chance to learn techniques and do experiments they never would have a chance to do in high school.
Warner Ervin of Houston is interested in animal science and learned how to tell male from female mosquitoes. His adviser, Craig Coates, studies the genes of mosquitoes that allow them to fight against malaria and yellow fever. Coates thought this experience would be fun and helpful to the high school students.
The agricultural research at A&M differs from stereotypes.It’s molecular(分子)science on the cutting edge,” Funkhouser says. The program broadened students’ knowledge. Victor Garcia of Rio Grande City hopes to become a biology teacher and says he learned a lot about chemistry from the program.
At the end of the program, the students presented papers on their research. They’re also paid $600 for their work— another way this program differs from others, which often charge a fee.
Fourteen students got paid to learn that science is fun, that agriculture is a lot more than milking and plowing and that research can open many doors.
43. The research program is chiefly designed for ________ .
A. high school advisers from Houston
B. college students majoring in agriculture
C. high school students from different places
D. researchers at the College of Agriculture and Life Sciences
44. It can be inferred from the text that the students in poorer areas________.
A. had little chance to go to college
B. could often take part in the program
C. found the program useful to their future
D. showed much interest in their high school experiments
45. When the program was over, the students________.
A. entered that college
B. wrote research reports
C. paid for their research
D. found way to make money
46. What would be the best title for the text?
A. A Program for Agricultural Science Students
B. A Program for Animal Science Students
C. A Program for Medical Science Lovers
D. A Program for Future Science Lovers

Grown-ups know that people and objects are solid. At the movies, we know that if we reach out to touch Tom Cruise, all we will feel is air. But does a baby have this understanding?
To see whether babies know objects are solid, T. Bower designed a method for projecting an optical illusion(视觉影像)of a hanging ball. His plan was to first give babies a real ball, one they could reach out and touch, and then to show them the illusion. If they knew that objects are solid and they reached out for the illusion and found empty air, they could be expected to show surprise in their faces and movements. All the 16-to 24-week-old babies tested were surprised when they reached for the illusion and found that the ball was not there.
Grown-ups also have a sense of object permanence. We know that if we put a box in a room and lock the door, the box will still be there when we come back. But does a baby realize that a ball
that rolls under a chair does not disappear and go to never-never land?
Experiments done by Bower suggest that babies develop a sense of object permanence when they are about 18 weeks old. In his experiments, Bower used a toy train that went behind a screen. When 16-week-old and 22-week-old babies watched the toy train disappear behind the left side of the screen, they looked to the right, expecting it to reappear. If the experimenter took the train off the table and lifted the screen, all the babies seemed surprised not to see the train. This seems to show that all the babies had a sense of object permanence. But the second part of the experiment showed that this was not really the case. The researcher substituted(替换)a ball for the train when it went behind the screen. The 22-week-old babies seemed surprised and looked back to the left side for the train. But the 16-week-old babies did not seem to notice the switch(更换).Thus, the 16-week-old babies seemed to have a sense of “something permanence,”while the 22-week-old babies had a sense of object permanence related to a particular object.
47. The passage is mainly about ________.
A. babies’ sense of sight
B. effects of experiments on babies
C. babies’ understanding of objects
D. different tests on babies’ feelings
48. In Paragraph 3, “object permanence” means that when out of sight, an object________.
A. still exists
B. keeps its shape
C. still stays solid
D. is beyond reach
49. What did Bower use in his experiments?
A. A chair.
B. A screen.
C. A film.
D. A box.
50. Which of the following statements is true?
A. The babies didn’t have a sense of direction.
B. The older babies preferred toy trains to balls.
C. The younger babies liked looking for missing objects.
D. The babies couldn’t tell a ball from its optical illusion

阅读下面短文并回答问题，然后将答案写到试卷规定的位置上（请注意问题后的字数要求）。
Taiwan police cannot decide whether to treat it as an extremely clever act of stealing or an even cleverer cheat. Either way, it could be the perfect crime, because the criminals are birds—horning pigeons!
The crime begins with a telephone message to the owner of a stolen car: if you want the car back, pay up! Then, the car owner is directed to a park, told where to find a bird cage and how to attach money to the neck of the pigeon inside. Carrying the money in a tiny bag, the pigeon flies off.
There have been at least four such pigeon pick-ups in Chan gwa. What at first seemed like the work of a clever stay-at-home car thief, however, may in fact be the work of an even lazier and more inventive criminal mind— one that avoid not only collecting money but going out to steal the car in the first place. Police officer Chen says that the crimi nal probably has pulled a double trick: he gets money for things he cannot possibly return. Instead of stealing cars, he lets someone else do it and then waits for the car-owner to place an ad in the newspaper asking for help.
The theory is supported by the fact that, so far, none of the stolen cars have been returned. Also, the amount of money demanded— under 3,000 Taiwanese dollars —seems too little for a car worth many times more.
Demands for pigeon-delivered money stopped as soon as the press reported the story. And even if they start again, Chen holds little hope of catching the crimina l. “We have more important things to do,” he said.

One possible version
Recently, as traditional Chinese festivals, such as the Mid-Autumn Day and the Dragon Boat Festival become official holidays, self-driving travel has become people’s preference in traveling.
The reasons why more and more people choose it are as follows. First, the economic development has made it possible for more people to buy their own private cars. What’s more, health-conscious people focus more on the quality of their life, so they will grasp every chance to
enjoy their life.
Every coin has two sides. While providing people with more chances to travel together with their family and friends, self-driving travel may also bring about some problems, such as the traffic jams on the high way or even the expressway.
Since people have to drive all the way during the tour, they have to pay special attention to the safety problem and avoid driving when exhausted.
