I’m a skeptic(怀疑论者) when it comes to the benefits of taking vitamins and other supplements. We swallow far more than any other country- yet we’re not the healthiest folks by far, nor do we live the longest.
There’s more bad news for vitamins this week: Turns out that takig folic acid(叶酸) and vitamin B12 supplements doesn’t prevent heart attacks or death, according to a major new study in the Journal of the American Medical Association. It was hoped they would, since the vitamins do reduce levels of homocysteine(高半胱氨酸), an amino acid(氨基酸) that is higher in the blood of people who have a higher risk of heart disease. In fact, homocysteine was reduced 30 percent after one year of treatment in the participants who took both vitamins. But in the following three years, just as many vitamin takers died as those who didn’t take the vitamins. Even worse, the study was stopped early because another similar study suggested that there may be an increased risk of cancer from taking B vitamins.
I had been taking a health-food store monster multivitamin(综合维生素剂) for months. Coincidentally, I had been experiencing some strange numbness in my legs that was starting to scare me. I remember sitting in a long meeting with my ankles crossed, and when I tried to stand up I crumpled on the floor and hit my chin on the glass coffee table because my leg had gone completely numb and worthless. As I sat there and shook my leg, I got that “pins and needles” feeling and soon was OK. But it scared me enough to make an appointment with a neurologist, who suggested an MRI to rule out multiple sclerosis, stroke, or a brain tumor(肿).
While I’ll never know for sure if the vitamins caused my problem, many, many studies have reminded us that pill forms of vitamins and minerals don’t provide the same benefit as getting them from food. There’s a lot we don’t know about how the human body works. Until we know more, I’m getting most of my vitamins from the farmer’s market.
49. What can we know from the last paragraph?
A. The writer is getting most of pill forms of vitamins from the markets.
B. The writer continues to take vitamins in great quantities.
C. The writer is getting vitamins from food, which can provide more benefits.
D. The writer will never take pill forms of vitamins and minerals.
50. Why do people take folic acid and vitamin B12 supplements?
They want to stop heart
attacks or live longer.
B. They want to live longer.
C. They want to increase risk of cancer.
D. They want to experience some strange numbness.
51. Which of the following is not true according to the passage?
A. It was the multivitamin he took that caused the writer to get the “pins and needles” feeling.
B. Taking more vitamins will not make a man healthier or live longer.
C. The vitamins can reduce levels of homocysteine in our body.
D. The less homocysteine in our blood, the less chance we’ll have heart attacks.
52. The best title of the passage can be _________.
A. Vitamins: Benefit Us a Lot B. Vitamins: No Help for Your Heart
C. Vitamins: Bad for the Brain, Too D. Some Bad News About Vitamins.

第二节读写任务(共1小题,满分25分)
阅读下面的短文,然后按照要求写一篇150词左右的英语短文。
In the past, the expression "children should be seen and not heard" summed up the attitude of parents to their children. Children were expected to be disciplined, well-behaved and the parents ruled the home. But today parents seem to do everything for their children and control all aspects of their lives. Some call this overparenting. Parents take charge of everything: from what pre-school their kids attend to the pastimes they take up. Parents feel they must protect their children to increase their chances for success. As a result children do less than ever before.
There are two reasons for overparenting. First, people now have fewer children than in years past so they can give each one more attention. Secondly, parents feel the future of their family is now dependent on only one child, so they must do as much as possible to help their child succeed.
But overparenting has negative consequences. Children are less independent now and are protected from the hardships and failures that teach them determination and give them the satisfaction of accomplishment. Also the pressure kids feel to be successful means they experience more anxiety and depression than ever before.

The Josephson Institute, a Los Angeles-based ethics institute, surveyed 29,760 students at 100 high schools nationwide, both public and private. The survey found that 35% of boys and 26% of girls admitted stealing from a store within the past year and 64% have cheated on a test, which suggests that today' s young people are less honest than previous generations.
However, Josephson addressed that today's youth are no less honest than their predecessors. "The question is not whether things are worse, but whether they are bad enough to attract concern. This is not a time to complain but to take thoughtful, positive actions. "
Roberta Gerold, superintendent of the Middle Country School District and a leader of the campaign, said parents and school officials need to be more diligent – for example, emphasizing to students the distinctions between original and borrowed work. "Adults are not taking this very seriously," he said. "The schools are not doing even the most moderate thing."
Nijmie Dzurinko, executive director of the Philadelphia Student Union, said the findings were not at all reflective of the inner-city students she works with as an advocate for better curriculum and school funding. "A lot of people like to blame society's problems on young people, without recognizing that young people aren't making the decisions about what's happening in society. "
Riddile, who for four decades was a high school teacher, agreed that more pressure could lead to more cheating, yet he said, "I would take these students over other generations. I found them to be more responsive, more rewarding to work with. We have to create situations where it's easy for kids to do the right things. We need to create classrooms where learning takes on more importance than having the right answer. "
60. According to the first paragraph, we know that __________.
A. the Josephson Institute is a Los Angeles-based public school
B. students in ethics institute are honest
C. cheating on tests is very common in America
D. more public school students admitted stealing
61. What does the underlined phrase "borrowed work" refer to?
A. Ideas taken from other person's works. B. Words borrowed from another language.
C. Homework assigned by the teachers. D. Work done by your classmates.
62. Which of the following statements is TRUE?
A. Riddile takes the young students over other generations.
B. Roberta Gerold found them to be more responsive.
C. Nijmie Dzurinko said the findings were reflective of the inner-city students.
D. Josephson addressed that today's youth are less honest than their predecessors.
63. According to the passage, we can infer that it's _________ that should be to blame for the problem.
A. the students B. previous generations C. public schools D. parents and schools

阅读下列短文,从每题所给的四个选项A、B、C、D中选出最佳选项。
The most frightening words in the English language are,“ Our computer is down.” You hear it more and more when you are on business. The other day I was at the airport waiting for a ticket to Washington and the girl in the ticket office said,” I’m sorry, I can’t sell you a ticket .Our computer is down.”
“If your computer is down, just write me out a ticket.”
“I can’t write you out a ticket. The computer is the only one allowed to do so.”
I looked down the counter(柜台)and every passenger was just standing there drinking coffee and staring at the blank screen. Then I asked her,” What do you do?”
“We give the computer the information about your trip, and then it tells us whether you can fly or not.”
“So when it goes down, you go down with it.”
“That ‘s right, sir.”
“How long will the computer be down?” I wanted to know.
“I have no idea .Sometimes it’s down for 10 minutes , sometimes for two hours. There is no way we can find out without asking the computer , and since it’s down, it won’t answer us.”
After the girl told me they had no spare computer ,I said, “ Let’s forget the computer. What about your planes? They’re still flying aren’t they?”
“I couldn’t tell without asking the computer.”
“Maybe I could just go to the gate and ask the pilot if he’s flying to Washington.” I suggested.
“I wouldn’t know what gate to send you to .Even if the pilot was going to Washington, he couldn’t take you if you didn’t have a ticket.”
“Is there any other airline flying to Washington within the next few hours?”
“I wouldn’t know,” she said, pointing at the dark screen.” Only ‘IT’ knows . ’IT’ can’t tell me.”
By this time there were quite a few people standing in lines .The words soon spread to other travelers that the computer was down Some people went, some people started to cry and still others kicked(踢) their luggage.
