The days are getting shorter and shorter, and temperatures are dropping. Winter is coming and it is easy for people to catch flu. Many people have started taking vitamin C pills as a precautionary(預(yù)防的)way. But a research has shown that vitamin C pills do not provide as much protection as they think. They are even not as good as other ways, like often washing your hands. Some German scientists have given people information and a test on the subject helping to stop incorrect ways.
Whether it is caused by cold or flu(流行性感冒), a runny nose and sore throat are signs of catching a cold. Many people overestimate(高估) the advantages of vitamin C and other pills. For years it was believed that taking vitamin C pills not only provided protection against colds but also against cancers, helping people to live longer. But the result of the research showed disagreement on these beliefs(看法). The result has now come out on the website wwww.informedhealthonline.org. “Some pills may not help people live longer. Some pills may even lead to earlier death,” says Professor Peter Sawicki. Scientists also say that the best way to get vitamins is through food instead of having vitamin pills. That is to say, we disagree with the way of taking vitamin C pills.
There are many simple but useful ways to lower the risk of catching a cold. These include often washing your hands with normal soap(肥皂) and water and not touching your face with your hands. People who have already had a cold can stop it from spreading by throwing away tissues(紙巾) at once after using them and not shaking hands with other people.

As we all know, the environment around us is getting worse and worse. In some places we can’t see fish   1  in the river or trees on the hills. Some people even have no clean water to drink.
Recently, a new lifestyle called low carbon life is   2  every corner of our country. The meanings of low carbon are   3  energy and no waste. It is such an important project that I can’t wait  4  my ideas on how to promote it.
First,we should   5  a no-car day every week in our school. Because cars not only cause serious air pollution but also waste energy.   6  the no-car day, neither students   7  teachers are allowed to drive to school. At the same time,just walk or run. Use our   8  and enjoy the fun.
Second, we had better not use plastic bags   9  . No one can stand the “white pollution”,   10  it is wise to use cloth bags which can   11  again and again.
12 ,one thing   13  we should keep in mind is that every big thing comes from the small details. So, as students, we ought to turn   14  the lights the moment we leave, use  15  sides of the paper, and reuse our textbooks and so on.

All in all, it weighs greatly for all of us to put the low carbon lifestyle into practice. Just set our mind to these:no-car days, no plastic bags, and no waste. Let’s do it now.

“Everything happens for the best.” Whenever I faced disappointment(失望),my mother would say this to me.
After I left college in 1932, I decided to find a job in radio as a sports announcer(廣播員). I went to Chicago and knocked at the door of every station. But unluckily, I was refused every time.
At one station, a kind lady told me that big stations wouldn’t hire(雇傭)a person without any experience and suggested that I try my luck at smaller stations. Following her advice, I went back to Dixon, where I had grown up. There were no such jobs in Dixon, and my father said a newly-opened store wanted a local athlete(運(yùn)動(dòng)員)to work for it . I wanted this job, but I was refused again.
“Everything happens for the best,” Mom reminded me. Dad offered me the car to look for a job. I tried WOC Radio in Davenport, Iowa. The program director, Peter MacArthur, told me they had already hired an announcer.
As I left his office, I felt so frustrated(沮喪). “How can I become a sports announcer if I can’t get a job in a radio station?” I asked aloud.
While I was waiting for the lift, I heard someone calling. It was MacArthur. “What was that you said about sports? Do you know anything about football?” Then he asked me to have a try. He was pleased with my performance, and he offered me a chance to work there.
On my way home, I thought of my mother’s words: “If you carry on, one day something good will happen. Something wouldn’t have happened if without the failure before.”
小題1:Why couldn’t the writer find a job at big radio stations?
A.Because he never graduated from college.
B.Because he didn’t work hard in college.

A.cbdaB.cbadC.bcdaD.bcad
小題3:Which of the following is TRUE?
A.The writer’s parents didn’ t want him to be a sports announcer.
B.There were no radio announcer jobs in the writer’s hometown.
C.The writer became uninterested in being a sports announcer.
D.The writer got a job as a sports announcer in Dixon at last.
小題4:According to the last paragraph, what did the writer’s mom want to tell him?
A.He shouldn’t be a sports announcer.
B.Disappointment leads to failure.
C.He should be proud of himself.
D.Everything will be OK if he keeps trying.
