Today, ultrasonic(超声的) waves are being put to work in laboratories and factories. If an ultrasound generator is placed in a liquid, the waves move the liquid back and forth hundreds of thousands of times each second. This causes materials to mix quickly or to dissolve(使分解，使溶解) in liquids. Paint manufacturers(制造商) use ultrasound to do a better job of blending colors. The companies that make film for your camera find that mixing chemicals by the use of sound waves will produce a more sensitive film.
The new lightweight(轻量的) type of washing machine uses ultrasonic waves to get clothes clean. Its special ultrasound generator is put into a pail of soapy water containing the soiled clothes. The sound waves drive the soapy water back and forth through the cloth so fast that everything is soon clean. There is also a new kind of dishwasher that works in much the same way.
Ultrasonic waves can shake a liquid so fast that tiny holes form all through it. The liquid is actually torn apart by this action. Almost as soon as these holes are made, they fall together again. The result is a powerful pounding action. In the dairy industry this is used for the double purpose of making homogenized(使均匀，使匀质) milk and sterilizing(使无菌) it at the same time. If you look at some raw milk with a microscope, you find that it is made up of little drops of butter fat floating around in a watery liquid. In order to make milk easier to digest, these fat droplets(微粒) may be broken up by forcing the milk through very small openings. The result is called homogenized milk. When the ultrasonic method is used, the sound waves not only break up the droplets but also kill the germs in the milk by pounding them to pieces. (from www.nmet168.com)

Some years ago, a Miami woman walking through an office building noticed two men standing together. Several minutes after her leaving, the men murdered a person working in the building. The police determined that the woman was the only 
witness and could possibly describe them. However, her memory of the men proved disappointingly unclear. Several days later, psychologist Ronald Fisher was brought in to obtain a more complete account from the woman. His interview produced a breakthrough—the woman reported a clear picture of one of the suspects. The important information enabled the police to arrest the suspect and close the case.
The police asked Fisher for help because of his rich knowledge in cognitive interview, a kind of memory-rebuilding process. Memory researchers have found that people trying to remember a past event often only recall(回忆) part of the relevant information. Human memory is selective and it is often distorted by stress. But a person’s accurate recall of an event or understanding of a question can be improved using specific interviewing techniques. The “cognitive interview” was developed in the late 1990s. It encourages the 
witness to take an active role in recalling information rather than giving answers only to some
one else’s questions. The witness first describes what happened in his or her own words, with no interviewer interruptions. 
The interviewer then goes further with specific techniques, such as having the witness tell the details of what happened from different perspectives (角度).
The cognitive interview focuses on guiding witnesses through four general recalling techniques: thinking about physical surroundings and personal feelings that existed at the time of past events; reporting everything that comes to mind about those events, no matter how broken it is; retelling events in a variety of time orders, such as from beginning to end, end to beginning, forward or backward; and adopting different perspectives while recalling events.
Experiments with police detectives trained in this demanding interview method find that they obtain nearly 50% more information from witnesses than before training, while error rates remain about the same. It is proved that cognitive interviews are quite important tools in improving the accuracy and completeness of witness testimony (证词). The purpose of the passage is to ______.
| A．give an account of a murder case |
| B．introduce an idea of cognitive interview |
| C．prove Fisher was an expert in cognitive interview |
| D．help a witness to recall information in a cognitive interview |
What is required to recall in a cognitive interview for a witness?
| A．The exact time at which a murder took place. |
| B．The information about the event in the time order. |
| C．The important things that come to his or her mind. |
| D．The surroundings and feelings at the time of the event. |
The key point in a cognitive interview is that ______.
| A．the witness is encouraged to take part in recalling information |
| B．the interviewer should interrupt the witness from time to time |
| C．the interview should take place outside the police station |
| D．the witness should recall details at the scene of the event |

When the young officer investigating(调查) the case notes that some of the evidence points to murder rather than suicide(自杀), Sayre finds herself unable to leave Destiny. She’s annoyed by Beck’s constant presence, and she is not sure if

The Worst Part
Mom is usually home on Sunday but this week she was going to a big golf game and 
I was all alone in the house. I was mad at Mom for divorcing Dad.
I kept looking at the telephone until I couldn’t stand it any longer. I picked up the receiver and dialed Dad’s number over in Bakersfield. I even remembered to dial I first because it was long distance. “You promised to phone me this week but you didn’t,” I said, feeling I had to talk to him.
“Take it easy, kid,” he said. “I just didn’t get around to it. I was going to call this evening. The week isn’t over yet.”
I thought about that.
“Something on your mind?” he asked.
“I hoped you would call, so I waited and waited.” Then I was sorry I said it.
“There was heavy snow in the morning,” he said, “I had to chain up on highway 80 and lost time.”
I know putting chains on eight big wheels i
n the snow is no fun. I felt a little better, as long as we were talking. “How is Bandit?” I asked.
There was a funny silence. For a minute I thought the line was dead. Then I knew something must have happened to my dog.
“Well, kid—”, he began. “My name is Leigh!” I almost yelled. “I’m not just some kid you met on the street!”
“Keep your shirt on, Leigh,” he said. “When I had to stop along with some other truckers to put on chains, I left Bandit out of the cab, I thought he would get back … I have sent out a call to CB radio, but I didn’t get an answer yet.” I was about to say I understood when there came the bad part, the really bad part. I heard a boy’s voice say, “Hey, Bill, Mom wants to know when we’re going out to get the pizza?”From the story we know that _______.

| A．his dad got remarried | B．his parents got divorced |

Why do men die earlier than women? The latest research makes it known that the reason could be that men's hearts go into rapid decline when they reach middle age.
The largest study of the effects of ageing on the heart has found that women's longevity may be linked to the fact that their hearts do not lose their pumping power with age.
“We have found that the power of the male heart falls by 20--25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
"Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70，one-third of those cells die and are not replaced in men,” said Goldspink. "This is part of the ageing process."
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman's heart could perform almost as well as a 20-year-old one's.
"This gender difference might just explain why women live longer than men,” said Goldspink.
They studied more than 250 healthy men and women between the ages of 18 and 80，focusing on healthy persons to remove the confusing influence of disease.
The team has yet to find why ageing takes a greater loss on the male heart, said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age. The underlined word “longevity" in the second paragraph probably refers to ______.
| A．health | B．long life | C．ageing | D．effect |
The text mainly talks about ______.
| A．men's heart cells | B．women's ageing process、 |
| C．the gender difference | D．hearts and long life |
If you want to live longer, you should
| A．enable your heart to beat much faster |
| B．find out the reason for ageing |
| C．exercise regularly to keep your heart healthy |
| D．prevent your cells from being lost |
We can know from the passage that
| A．the reason why ageing takes a greater loss on the male heart has been found out |
| B．scientists are on the way to finding out why the male heart loses more of the cells |
| C．the team has done something to prevent the male from suffering the greater loss |
| D．women over 70 could lose more heart cells than those at the age of 20 |
