Water problems in the future will become more intense and more complex. Our increasing population will tremendously increase urban wastes, primarily sewage. On the other hand, increasing demands for water will decrease substantially the amount of water available for diluting wastes. Rapidly expanding industries which involve more and more complex chemical processes will produce larger volumes of liquid wastes, and many of these will contain chemicals which are noxious. To feed our rapidly expanding population, agriculture will have to be intensified. This will involve ever - increasing quantities of agricultural chemicals. From this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problem. There are two ways by which this pollution problem can be dwindled(减少). The first relates to the treatment of wastes to decrease their pollution hazard . This involves the processing of solid wastes " prior to " disposal and the treatment of liquid wastes, or effluents, to permit the reuse of the water or minimize pollution upon final disposal . A second approach is to develop an economic use for all or a part of the wastes. Farm manure is spread in fields as a nutrient or organic supplement. Effluents from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained. Effluents from other processing plants may also be used as a supplemental source of water. Many industries, such as meat and poultry processing plants, are currently converting former waste products into marketable byproducts. Other industries are potential economic uses for waste products. 1.The purpose of this passage is ________. A．to alert the reader to the dwindling water supply B．to explain industrial uses of water C．to acquaint the reader with water pollution problems D．to demonstrate various measures to solve the pollution problem 2.Which of the following points is NOT included in the passage? A．Industrial development includes the simplification of complex chemical processes. B．Diluting wastes needs certain amount of water. C．Demands for water will go up along with the expanding population . D．Intensive cultivation of land require more and more chemicals. 3.The reader can conclude that _________. A．countries of the world will work together on pollution problems B．byproducts from wastes lead to a more prosperous marketplace C．science is making great progress in increasing water supplies D．some industries are now making economic use of wastes 4.The author gives substance to the passage through the use of________. A．interviews with authorities in the field of water controls B．opinions and personal observations C．definitions which clarify important terms D．strong arguments and persuasions 5.The underlined words "prior to"(para. 2)probably man________.

2 . A new study has found that social media could be affecting the sleep of young adults. The study is a project of researchers at the University of Pittsburgh’s School of Medicine.They found that young people who often use social media are more likely to suffer from sleep disorders than those who use social media less. The researchers say doctors should ask young adults about their use of social media when treating sleep problems.“This is one of the first piece of evidence that social media use really can affect your sleep,” said Jessica C. Levenson, the lead author of a report on the study. The researchers set out to examine the connection between social media and sleep among young adults.The researchers wanted to find out how often young people used social media sites like Facebook. For the study, they gave questionnaires to nearly 1,800 adults, aged 19 to 32. On average, members of the study group used social media sites one hour a day. They also visited various social media accounts 30 times per week.Thirty percent of the study’s participants(参与者)reported having serious problems with sleeping. Those people who used social media a lot were three times more likely to have a sleep disorder. And those who spent the most time on social media were twice as likely to suffer from sleep problems.Researchers say social media can influence sleep in a number of ways. People can lose sleep by staying up too late looking at social media. Sensitive issues argued about on social media can cause excitement. Using an electronic device can disturb a body’s natural sleep rhythms because of the light coming from screens. The researchers note that in some cases, young adults who have a hard time sleeping may use social media to help them fall asleep, which may in turn lead to more problems sleeping because social media involve screen time that is interesting and can keep you awake.【小题1】What do the researchers suggest on a doctor’s treating young adults’ sleep problems?A．Knowing their living environment.B．Asking about the time they spent on social mediaC．Asking what social media sites they use.D．Inquiring about their sleeping habits.【小题2】What can we know about the study?A．Less than one-third of the participants in the study have problem sleeping.B．Doctors don’t think there is any way to cure sleeping problems caused by social media use.C．Social media use has something to do with young adults’ sleeping problems.D．Participants who like using Facebook are less likely to suffer from sleeping problems.【小题3】Social media use affects one’s sleep in the following ways except that ________.A．one will stay up lateB．one can get excited.C．one’s sleep rhythms will be disturbedD．one can fall fast asleep【小题4】What is the main idea of the passage?A．Social media have affected young adults’ sleep.B．How to deal with sleep problems.C．Social media takes up so much time.D．Sleep problems mainly result from social media.【小题5】The main purpose of the passage is to ________.A．informB．encourageC．persuadeD．advise

The increase in international business and in foreign investment has created a need for executives with knowledge of foreign languages and skills in cross-cultural communication. Americans, however, have not been well trained in either area and, consequently, have not enjoyed the same level of success in negotiation in an international arena as have their foreign counterparts. Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator’s role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator’s position. Two traits in particular that cause cross-cultural misunderstanding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding.

question or statement.Hot pot is a traditional dish in China. It is believed to date back more than 1,000 years to the time of the Jin Dynasty. Hot pot's origins can be found in the dining practices of Mongolian horsemen who rode across the steppe and into northern China. Legend has it that the Mongols used their helmets as pots to simmer (炖) broth (汤底) over open fires, and cooked chunks of meat in the broth.Hot pot cooking seems to have spread to northern China during the Tang Dynasty. In the regional variations developed with different ingredients such as seafood. In the centuries that witnessed the growth of the Song Dynasty, hot pot moved — and changed — further south, with each successive region adapting it to their local ingredients and tastes.The ingredients in a hot pot vary a lot from region to region. Perhaps the most famous hot pot is the Chongqing or Sichuan hot pot. It features a dark red broth chock-full (塞满了的) of spices, chili peppers, and the uniquely mouth-numbing Sichuan peppers. In Beijing and elsewhere in the north, hot pot broth tends to be mild and, compared to its racy southern "cousins", a little light. In the northeast of China, a kind of local sauerkraut (酸菜) is used to add some tang (强烈的味道), making the broth a bit sour. People can choose a version of hot pot according to their taste.1 Hot pot is believed to date back more than 1,000 years to the time of _______.A. the Jin Dynasty B. the Tang DynastyC. the Song Dynasty D. the Yuan Dynasty

The Harry Potter series, written by J.K. Rowling, is perhaps the most popular set of novels of the modern era. With seven books and many successful films to its name, the series has gathered about 15 billion dollars in sales. How did the series become so popular? The reason can be broken down into several areas.The first book in the series was rejected 12 times before it was picked up by Bloomsbury—a small publisher in England. So receiving this contract was Rowling's first step to success. However, getting a book contract does not ensure the success of a book. The story was soon loved by children and adults alike. In light of this, Bloomsbury Publishing published a second version of the books with “adult” (less colorful and more boring) book covers. This made it easier for a full range of ages to enjoy the series.Another factor that worked like a charm was that the publisher and Rowling herself, through the books, conducted midnight releases, promotions, and pre-ordering more readers. Customers who feared that their local bookstore would run out of copies responded by pre-ordering over 700,000 copies before the July 8, 2000 release.What does the underlined word “releases” (Para. 3) mean?A. The activity that frees or expresses energy or emotion.B. The announcement about the book’s publishing information.C. The sales of books that is available only at midnight.
