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________.

A．after    B．during   C．before   D．beyond

Controlling traffic is a complex and high cost problem in many developed countries. It becomes more difficult and costly with the ever-increasing number of cars on the roads. But scientists and students at the CATT, at the University of Maryland are working to solve this problem. They are using simulation(模拟) technologies to help government and private business control and react to 　　 changing traffic conditions.

The online economics magazine Forbes.com says traffic congestion(拥挤) cost Americans $ 124 billion in 2014 and that number could rise to $ 186 billion by 2030.

But scientists at the CATT lab are trying to reduce those costs. They are developing a system that helps traffic managers, planners, emergency workers and businesses plan and react better. Michael Pack is CATT director. He says the system is important to help emergency workers, or first responders. reach an accident area faster.

The CATT Lab collects information from many sources, including roadside devices, GPS (global positioning system) equipment and wireless phones.

About 60 students and 30 software developers observe traffic flow and manage the computer servers at all times. They also work to develop software and applications that can help traffic run smoother and safer, Some of them turn the information gathered into so-called "visualizations". These visual representations help emergency workers better understand what is happening.

The center shares its findings with firefighters, police. Transportation departments and the military. They also share information with universities and transportation company.The technology company Google uses the data for its traffic-related websites. Michael Pack says, the information is then shared with anyone who wants to help traffic run more smoothly.

Mr. Pack says the goal is to help develop an intelligent system of road signals that will communicate with each other and with vehicles on the road.

1.The second paragraph is written to

A. attract more people to look through Forbes.com.

B.tell readers what Forbes.com says on its websitrre

C. show how much money controlling costs America

New research has found that young adults who smoke both tobacco cigarettes and e-cigarettes appear to have a higher risk of stroke than those who only smoke tobacco.

Carried out by researchers at George Mason University, the new study looked at 161,529 participants aged 18 to 44 years of age, who were surveyed about their cigarette and e-cigarette use.

The researchers also calculated the participants’ risk of experiencing a stroke, taking into account factors such as how much participants smoked, high blood pressure, diabetes, cholesterol levels, body mass index and physical activity levels.

The findings, published in the American Journal of Preventive Medicine, showed that the participants who smoked cigarettes and used e-cigarettes were nearly two times more likely to have a stroke compared to current cigarette — only smokers, and nearly three times more likely than non-smokers.

The team also found that participants who used only e-cigarettes had a lower risk of stroke than those who smoked only tobacco cigarettes. In fact, those who used e-cigarettes on their own did not have a significantly greater risk of stroke than non-smokers.

However, the researchers failed to find any clear benefit from switching from cigarette smoking to using e-cigarettes, even though many people believe that e-cigarettes are a “healthy” alternative to cigarettes, and a way to help smokers kick the habit. They also noted that the nicotine dependence and toxicity associated with e-cigarettes is worrying, particularly among young adults who smoke them for fun and the range of flavors.

“It’s long been known that smoking cigarettes is among the most significant risk factors for stroke. Our study shows that young smokers who also use e-cigarettes put themselves at an even greater risk,” explained lead investigator Tarang Parekh, MBBS, MSc. “This is an important message for young smokers who perceive e-cigarettes as less harmful ones and consider them a safer alternative.We have begun understanding the health impact of e-cigarettes and concomitant cigarette smoking, and it’s not good.”

“Our findings demonstrate an additive harmful effect of e-cigarettes on smokers’ blood vessels, hearts and brains,” explained Parekh.

“Consider this study as a wake-up call for young vapers, clinicians, and healthcare policymakers. There is an urgency to regulate such products to avoid economic and population heath consequences and a critical need to conduct further research on the benefits and risks of smoking cessation altermatives,” warned Parekh.

1.What does the text belong to?

A.A science fiction. B.A news report.

C.A short story. D.A public announcement.

2.What can we know about the participants?

A.A few elderly people were surveyed.

B.Some of them are non smokers .

C.All of them use cigarettes and e-cigarettes.

D.They have a lower risk of stroke than others .

3.What does the underlined word “perceive” in Paragraph 7 mean?

A.Think. B.Practise.

4.What did the the new research find?

A.Smoking cigarettes is among the most significant risk factors for stroke.

B.E-cigarettes are a “healthy” alternative to cigarettes.

C.Smoking both tobacco and e-cigarettes can make young adults at an greater risk of stroke.

Play is the basic business of childhood, and more and more in recent years research has shown the great importance of play in the development of a human being．From earliest infancy （婴儿）, every child needs opportunity and the right material for play, and the main tools of play are toys．The main function of toys is to suggest, encourage and assist play．To succeed in this, they must be good toys, which children will play with often, and will come back to again and again．Therefore, it is important to choose suitable toys for different stages of a child’s development.

In recent years research on infant development has shown that the standard a child is likely to reach, within the range of his inherited abilities, is largely determined in the first three years of his life．So a baby’s ability to benefit from the right play materials should not be underestimated．A baby who is encouraged, talked to and shown things and played with, has the best chance of growing up successfully．

The next stage, from three to five years old, curiosity knows no bounds．Every type of suitable toy should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability. Bricks and jigsaws and construction toys; painting, scribbling and making things; sand and water play; toys for imaginative and pretending play; the first social games for learning to play and get on with others．

By the third stage of play development—from five to seven or eight years old— the child is at school．But for a few more years play is still the best way of learning, at home or at school．It is easier to see which type of toys the child most enjoys．

Until the age of seven or eight, play and work mean much the same to a child．But once reading has been mastered, then books and school become the main source of learning．Toys are still interesting and valuable, which lead up to new hobbies, but their significance has changed —to a child of nine or ten years old, toys and games mean, as to adults, relaxation and fun.

1.60. The writer wants us to understand that a child_______.

2.61. According to the passage, the abilities a child has inherited from his parents ________.

3.62. The passage tells us that children are the most curious when they are about______.

4.63. The article is about_______.

Treatment for HIV has become more widespread, especially in poorer countries. It's also become cheaper, as medicine companies have lowered their prices for life-saving anti-retroviral drugs(抗逆转录病毒药物). But these drugs are still expensive and many countries are looking to create the biggest impact with limited resources. That's where World Health Organization guidelines come in, says Rochelle Walensky, a disease researcher from Harvard.

Walensky and her colleagues used computer programs to model the most cost-effective disease interventions(干预), as well as collected data from clinics in Africa and India about what works best. They found that among the choices of what to do first, earlier anti-retroviral therapy (疗法)improved five-year survival dramatically and resulted in the longer life expectancy. But cost-effective doesn't always mean affordable, especially for governments in poor countries. Countries still have to make difficult choices about how much treatment they can afford.

People in Nairobi, Kenya on Thursday, Dec. 9, 2010, protest a potential free trade area agreement between the EU and India that could see cheap anti-AIDS drugs phased out（逐步淘汰）. However, Walensky notes that first-line anti-retrovirals—those medicine given to newly diagnosed patients that can keep away from symptoms for years - are much cheaper than they were a decade ago. "Second-line therapy have come down quite a bit but not to the level of first-line and countries are having a hard time affording them and increasingly over time, people are going to fail first-line therapy and they're going second-line therapy and then, eventually, they're going to need third-line therapy, some of them."

According to Walensky, history has shown that drug prices can come down when international pressure is applied to drug makers. But for now, she says, countries should focus on treating as many people as they can, as early as possible

Her paper is published in the online journal PLoS Medicine.

1. Which is the best title for the passage?

A. HIV Has Spread in Poorer Countries       B. Rochelle Walensky’s Life

C. International Pressure to Drug Makers        D. Early HIV Treatment Saves Lives

2. Which of the following is TRUE according to the passage?

A. Anti-retroviral drugs have become cheap now.

B. The cost-effective treatment may be a heavy expense.

C. Cheap anti-AIDS drugs have been phased out .

D. First-line therapy deals with the most severe disease.

3. The research is done by________.

A. using computer programs and collecting data from clinics

B. giving medicine to newly diagnosed patients with AIDS

C. urging countries to focus on treating more patients earlier

D. publishing her paper in the online journal PLoS Medicine

4. The passage serves as a（n）___________ to Rochelle Walensky 's study.

A. assessment           B. comment          C. introduction     D. background
