Passage two
　　P. P never wanted to be a national public figure. All she wanted to be was a mother and a homemaker. But her life was turned upside down when a motorist distracted by his cell phone, ran a stop sign and crashed into the side of her car. The impact killed her two-year-old daughter. Four months later, P. reluctantly but courageously decided to try to educate the public and to fight for laws to ban drivers from using cell phones while a car is moving. She wanted to save other children from what happened to her daughter. In her first speech, P. got off to a shaky start. She was visibly trembling and her voice was soft and uncertain. But as she got into her speech, a dramatic transformation took place. She stopped shaking and spoke with a strong voice. For the rest of her talk, she was a forceful and compelling speaker. She wanted everyone in the audience to know what she knew without having to learn it from a personal tragedy. Many in the audience were moved to tears, and to action. In subsequent presentations, P. gained reputation as a highly effective speaker. Her appearance on a talk show was broadcast three times transmitting her message to over 14,000,000 people. Her campaign increased public awareness of the problem and prompted over 300 cities and several states to consider restrictions on cell phone use.
　　29. What was the significant change in P. P.’s life?C. She became a public figure.
　　30. What had led to P.’s personal tragedy?D. A motorist’s failure to concentrate.
　　31. How did P. feel when she began her first speech?A. Nervous and unsure of herself.
　　32. What could be expected as a result of P.’s efforts?B. Restrictions on cell phone use while driving.

Passage 3
　　Many people catch a cold in the springtime or fall. It makes us wonder if scientists can send a man to the moon, why can’t they find a cure for the common cold? The answer is easy. There’re actually hundreds of kinds of cold viruses out there. You never know which one you will get, so there isn’t a cure for each one. When a virus attacks your body, your body works hard to get rid of it. Blood rushes to your nose and causes a blockage in it. You feel terrible because you can’t breathe well. But your body is actually eating the virus. Your temperature rises and you get a fever. But the heat of your body is killing the virus. You also have a running nose to stop the virus from getting to your cells. You may feel miserable but actually your wonderful body is doing everything it can to kill the cold. Different people have different remedies for colds. In the United States and some other countries, for example, people might eat chicken soup to feel better. Some people take hot baths and drink warm liquids. Other people take medicines to relieve various symptoms of colds. There’s one interesting thing to note. Some scientists say taking medicines when you have a cold is actually bad for you. The virus stays in you longer because your body doesn’t develop a way to fight it and kill it.
　　33. According to the passage, why haven’t the scientists find a cure for the common cold? B. There are too many kinds of cold viruses for them to identify.
　　34. What does the speaker say about the symptoms of the common cold? D. They show our body is fighting the virus.
　　35. What do some scientists say about taking medicines for the common cold according to the passage? A. It actually does more harm than good.
