Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu may make a difference in how long the misery lasts.
The American Lung Association (ALA) has issued new guidelines on combating colds and the flu(流感), and one of the keys is being able to quickly tell the two apart. That's because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.
The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses - flu A, B and C. There is no cure for either illness , but the flu can be prevented by the flu vaccine, which is, for most people, the best way to fight the flu, according to the ALA. But if the flu does strike, quick action can help. Although the flu and common cold have many similarities , there are some obvious signs to look for.
Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms.
The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms.
Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome(综合症) ,a rare but serious condition of the liver and central nervous system.
There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one.
According to the author, knowing the cause of the misery will help ________.
A) shorten the duration of the illness
B) the patient buy medicine over the counter
C) the patient obtain cheaper prescription drugs
D) prevent people from catching colds and the flu
We learn from the passage that ___________.
A) one doesn't need to take any medicine if he has a cold or the flu
B) aspirin should not be included in over-the-counter medicines for the flu
C) delayed treatment of the flu will harm the liver and central nervous system
D) over-the-counter drugs can be taken to ease the misery caused by a cold or the flu
According to the passage, to combat the flu effectively, ___________.
A) one should identify the virus which causes it
B) one should consult a doctor as soon as possible
C) one should take medicine upon catching the disease
D) one should remain alert when the disease is spreading
Which of the following symptoms will distinguish the flu from a cold?
A)A stuffy nose. B) A high temperature.
C)A sore throat. D) A dry cough.
If children have flu-like symptoms, their parents _______________.
A) are advised not to give them aspirin
B) should watch out for signs of Reye syndrome
C) are encouraged to take them to hospital for vaccination
D) should prevent them from mixing with people running a fever

It’s as important to live well as it is to study well, I think. I went to bed no later than 11:30 pm. It put me in the right mood for the next day. I didn’t follow a special diet (饮食), but I did make sure I ate a nutritious breakfast each day.

The person who plays well, studies well. Having a lot of schoolwork doesn’t mean having to give up on every other activity. I played basketball or took a walk to relax when I felt tired. Time out is not a waste of time but helps you study more efficiently.

Besides taking the big exam, you have other choices for college. I took the independent enrollment (自主招生) exam held by Peking University and some other students even prepared to study abroad. Pay attention to any relevant information you can find, whether it’s from school, the news media or another source.

【小题1】Zhang Xu is an active and energetic boy who enjoys many sports like swimming, football, badminton, cycling and jogging. He has a lot of friends at school and they often spend a lot of time on rivers, fields and mountains. Is it good to spend so little time in the library? How to allocate time between academic lectures and outing? That's his problem.
【小题2】Xiao Lili has much difficulty m catching up with her classmates m chemistry and physics. But her superiority lies in music and English, so she is dreaming of becoming a professional singer. She hopes that her strong points can help pave her way to future success. "Can I go to a musical college without taking NMET?" she wonders.
【小题3】Guo Jie is a hardworking boy but, unfortunately, he gets low marks in every test. He is always busy with his own study plan. When he didn’t finish his work the earlier day, he will bury his mind in his work to fulfill his plan, ignoring the teacher’s lectures. “How can I raise my marks?” he is puzzled.
【小题4】Song Siwei is a slim and pretty girl, who works hard at all her lessons. But she was so absorbed in her studeies that she is even unwilling to tear herself off at meal times. She is always the last to leave the classroom and the first to arrive. She starts to feel dizzy and have headaches. “What might happen to me?” she wonders.
【小题5】Zhang Lan is a charming girl who is active both in the classroom and on the sports field. She is kind to all her classmates. Some boys in her class tend to talk to her at every possible opportunity and even invite her to meals. That makes her pleased but costs her quite some time. She doesn’t know whether it is right to accept kindness from the boys.
When I was growing up, I was ashamed to be seen with my father. He was severely disabled and very short, and when we would walk together, his hand on my arm for balance, people would stare. If he ever noticed or was bothered, he never let on.
It was difficult to coordinate(协调)our steps—his slow, mine impatient—and because of that, we didn’t say much as we went along. But as we started out, he always said, “You set the pace. I will try to adjust to you.”
He never talked about himself as an object of sympathy, nor did he show any envy of the more fortunate or able. What he looked for in others was a “good heart”, and if he found one, the owner was good enough for him. I believe that is a proper standard by which to judge people, even though I still don’t know accurately what a “good heart” is.
Unable to join in many activities, my father still tried to participate in some way. I now know he participated in some things indirectly through me, his only son. When I played ball (poorly), he “played” too. When I joined the Navy, he “joined” too. And when I came home on leave, he saw to it that I visited his office. Introducing me, he was really saying, “This is my son, but it is also me, and I could have done this, too, if things had been different.” Those words were never said aloud.
He has been gone many years now, but I think of him often. I wonder if he sensed my unwillingness to be seen with him during our walks. If he did, I am sorry I never told him how sorry I was, how unworthy I was, how I regretted it. I think of him when I complain about small affairs, when I am envious of another’s good fortune, when I don’t have a “good heart”.
At such times I put my hand on his arm to regain my balance, and say, “You set the pace. I will try to adjust to you.”
