Passage one
Last August,Susan and 42 other students got wet and dirty while removing six tons of garbage from the river running across their city.They cleaned up the river as part of a week-long environmental camp. Like one in three American rivers,this river is so polluted that it's unsafe for swimming and fishing,still,Susan,who has just completed her third summer on the river clean-up ,scene has changed in this river."Since we started three years ago ,the river is getting a lot cleaner",she says.Environmental scientists praised the teenagers for removing garbage that can harm wild life.Waterbirds,for example,can choke on plastic bottle rings and get cut by scrap 23 metal.Three years ago,when the clean-up started,garbage was everywhere,but this year,the teenagers had to hunt for garbage.They turn the clean-up into a competition to see who could find the most garbage and unload 24 their boats fastest. By the end of the six hour shift,they have removed enough garbage to fill more than two large trucks."Seeing all their garbage in the river makes people begin to care about environmental issues,"Susan says.She hopes that when others read that she and her peers 25 care enough to clean it up, maybe they will think twice before they throw garbage in the river.
Questions 11-13 are based on the passage you have just heard.
11.What does the passage tell us about American rivers?
12.What did the students find when they came to the river this year?
13.What is the expected reaction of the local people to the students' efforts?
Passage two
Why do we cry? Can you imagine life without tears? Not only do tears keep your eyes lubricated 26, they also contain a substance that kills certain bacteria so they can't infect your eyes. Give up your tears ,and you'll lose this on-the-spot defense 27. Nobody wants to give up the flood of extra tears you produce when you get something physical or chemical in your eyes.Tears are very good at washing this irritating stuff out .Another thing you couldn't do without your tears is cry from joy, anger or sadness.Humans are the only animals that produce tears in response to emotions, and most people say a good cry makes them feel better.Many scientists,therefore,believe that crying somehow helps us cope with emotional situations. Tear researcher,Winifred, is trying to figure out how it happens. One possibility he says is that tears discharge certain chemicals from your body, chemicals that build up during stress. When people talk about crying it out,"I think that might actually be what they are doing",he says.If Fred is right,what do you think will happen to people who restrain their tears? Boys, for example ,cry only about a quarter as often as girls once they reach teenage years, and we all cry a lot less now than we did as babies .Could it possibly be that we face less stress? Maybe we found another ways to deal with it ,or maybe we just feel embarrassed.
Questions 14-17 are based on the passage you have just heard.
14.What's the topic discussed in this passage?
15.What is Winifred trying to find out?
16.What does the passage say about teenage boys and girls?
17.What's the difference between human beings and other animals when shedding tears?
Passage three
Imaging this:you wake up each morning to find your sister lying beside you,to get dressed and tie your shoes, you use one hand and she uses another. You do everything out together,too,even sitting on the same chair at lunch and riding on the same bicycle. That's what life is like for six-year-old Betty and Abby. Like most twins, the two girls look very much alike,but unlike most twins,Betty and Abby share parts of the same body .Twins like Betty and Abby are rare. Only about 40 sets are born in the United States each year. Few survive as long as Betty and Abby .That's because twins often share vital organs, like a heart or brain. The shared organs are often badly shaped and may not be strong enough to support both twins. But Betty and Abby each has her own head, heart and stomach which function normally 28 .Because she has three or four lungs which provide plenty of oxygen for both twins. Most of their completely shared organs lie below the waist. Betty And Abby live relatively 29 normal lives.They attend a regular school ,and each does her own school work .They prefer to do some projects together,though ,for example,to cut out paper dolls ,one twin holds the paper,while the other uses the scissors. But sometimes,the girls don't want to do the same thing, for example, sometimes they want to play with different toys. What do they do then? "We toss 16 a coin",says Abby .
Questions 18-20 are based on the passage you have just heard.
18.In what aspect ,do Betty and Abby differ from most twins?
19.What does the passage tell us about twins who share parts of the same body?
20.What does the passage say about the education of the twin girls?
B) He will wash the dishes himself instead.
