23、ats, stuffy（堵塞）noses and body aches all result in discomfort, but being able to tell if the cause is a cold or flu may make a difference in how long the discomfort lasts, because the drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts
24、 taking over the medications available, 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
25、 flu vaccine（疫苗）, which is, for most people, the best way to fight the flu, according to the ALA.But 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.Cod symptoms such as stuffy nose, running nose and scratc
26、hy throat typically developed 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 coldness, painful throat and body aches come on suddenly and are more worry
27、ing than cold symptoms.The ALA notes that it may be particularly difficult to tell when babies 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 the medications as well. However,
28、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）.There is, of cause, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the probability catching one.51. Acco
29、rding to the author, knowing the cause of the discomfort will help _.A. prevent people from catching colds and the fluB. the patient obtain cheaper drugsC. the patient buy medicineD. shorten the period of the illness52. We learn from the passage that _.A. the drugs available can be taken to ease the
30、 discomfort caused by a cold or the fluB. one doesnt need to take any medicine if he has a cold or the flueC. aspirin should not be included in the medicines for the fluD. delayed treatment of the flu will harm the liver and central nervous systems53.

33、n how to say sorry ,you must be good at saying it yourself, especially to your own children. But how you say it can be quite tricky.If you say to your children “Im sorry I got angry with you, but. “, what follows that “but“ can make the apology ineffective: “I had a bad day“ or “your noise was givin
34、g me a headache“ leaves the child who has been injured feeling that he should be apologizing for his bad behavior.Another method by which people appear to apologize without actually doing so is to say “Im sorry youre upset“; this suggests that you are somehow at fault for allowing yourself to get up
35、set by what the other person has done.These pseudo(虚假的)-apologies are used by people who believe saying sorry shows weakness. Parents who wish to teach their children to apologize should see it as a sign of strength, and therefore not turn to these pseudo-apologies.But even when presented with examp
36、les of true regret, children still need help to become aware of how difficult it is to say sorry. A three-year-01d might need help in understanding that other children feel pain just as he does, and that hitting a playmate over the head with a heavy toy requires an apology. A six-year-old might need
37、 reminding that spoiling other childrens expectations can require an apology. A 12-year-old might need to be shown that taking away the biscuit tin without asking permission is acceptable, but that borrowing a parents clothes without permission is not.56.

39、e good reason to get upset B. I apologize for hurting your feelingsC. Im wrong for making you upset D. I know youre upset, but Im not to blame58.

40、 tolerantC. parents need to set them a good exampleD. the difficulties involved should be taken no notice of59. It can be inferred from the passage that apologizing properly is _.A. not necessary among family members B. a sign of social progressC. not as simple as it seems D. a matter calling for im

They thought someone was poisoning the people on purpose but no one knew how it was possible. Soon people took the position that the pork was poisoned. It was a pop
42、ular food everyone ate and it could have possibly made everyone sick. Anyone who had possession of pork would throw it out. Even the poorest of the poor wouldnt eat pork. Signs were posted on poles and letters were sent to everyone to warn people of the pork. Shortly afterwards, even policemen in hi
43、gh positions were also getting sick.Soon it became political and popular. Politicians rushed to the town to talk about politics and promised how they would find the solution if they were elected.
