高一英语单项填空简单题查看答案及解析

Sleep is a basic necessity of life and it is as important to our health as air, food and water. When we sleep well, we wake up feeling energetic, alert and ready to face daily challenges. When we don’t every part of our lives can suffer.

A survey made by the 2002 National Sleep Foundation (NSF) in America found that 74 percent of American adults are experiencing a sleep problem a few nights a week or more and 39 percent get less than 7 hours of sleep each night and want to have a sleep during the day.

Getting enough continuous quality sleep influences how we feel and perform next day. Getting enough sleep refers to the amount of sleep you need not to feel tired next day. Although sleep experts generally recommend an average of 7-9 hours each night, some people can get along with less while others need as many as ten hours to feel energetic next day. Sleep requirements vary(变化)over the life cycle. Newborns and babies need a lot of sleep and have several periods of sleep throughout a 24-hour time period. Teenagers’ sleep patterns turn to a later sleep-wake cycle, but they still need around 9 hours of sleep. Throughout adulthood, even as we get older, we need 7-9 hours of sleep. Sleep patterns may change, but the need for sleep remains the same.

According to the 2002 poll. Over 80 percent of American adults believe that not getting enough sleep leads to poor performance at work, risk of injury, poor health and difficulty getting along with others. Often, people become easily annoyed due to lack of sleep. Recent research suggests that lack of sleep also leads to approximately 100,00 sleep-related traffic accidents each year and results in 1,500 deaths.

If you are having sleep problems, turn to a sleep diary published by the National Sleep Foundation. A sleep diary helps you examine some of your health and sleep habits so that you and your doctor can find some reasons for poor sleep. Establishing a regular bed and wake-up schedule may also help you sleep well. Besides, talking to your doctor or a sleep specialist is of great help. Most sleep disorders can be successfully treated once properly diagnosed(诊断).

高一英语单项填空简单题查看答案及解析

Besides giving off gases and dusts into the air, humans produce waste that is poured on the environment. Often, this waste produced by major industries and people is harmful to both nature and human life.

One of the main causes of the large amount of dangerous waste is that people do not realize how large a problem it is. Because it can be simply removed and sent to a landfill(废渣填埋场),the problem is often believed to end there. In addition, industries have often shown an unwillingness to find ways to deal with dangerous waste because of the related expenses. Many industries and governments build simple landfills to store waste, and often just pour waste chemicals into nearby bodies of water. Often, chemicals used for industrial production cause dangerous forms of waste.The amount of these chemicals has increased greatly in the past, but it is often difficult and expensive to get rid of these chemicals or to store them in a way safe to human life and the environment.

Every year, major health problems result from dangerous waste. Sadly, it is often only after someone has died or become seriously ill that governments will take measures to reduce levels of harmful waste.

Some governments have realized how serious the dangerous waste problem is and are now trying to settle this problem. They are also trying to limit the amount of waste industries are allowed to produce.

Not only governments but ordinary people as well must work together to solve the problem. They can choose not to buy those products which require the production of dangerous waste, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one third using existing technologies and methods.

1.What would be the best title for the text?

A．Measures of Reducing Dangerous Waste

B．Danger of Harmful Waste to Mankind

C．Dangerous Waste and Water Pollution

D．Environmental Protection

2.According to the text, people ________ .

A．do not produce harmful waste in their daily life

B．do not know where to place the dangerous waste

C．are not clear about how serious the dangerouswaste problem is

D．are not sure about where harmful waste ends

3.What troubles industries most in dealing with the dangerous waste problem?

A．How to get government support.

B．How to increase their production.

C．How to store harmful waste.

D．How to cut down the related costs.

4. What can be inferred from the passage?

A．The polluting industries are not allowed to sell their products.

B．Present technologies have settled the harmful waste problem.

C．Everyone should obey the government rules for the problem.

D．To solve the problem requires the efforts of the whole society.
