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(廢渣填埋場),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.
【小題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
【小題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．a(chǎn)re not clear about how serious the dangerouswaste problem is
D．a(chǎn)re not sure about where harmful waste ends
【小題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.
【小題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.

Millions of people around the world cook their food over smoky fire every day.It is often difficult to find wood for the fire .People who do not have wood must spend large amounts of money on cooking fuel. However, there is a much easier way to cook food using energy from the sun.
Solar cooker, or ovens,have been used for centuries.A Swiss scientist made the first solar oven in seventeen sixty-seven. Today ,people are using solar cookers in many countries around the world. People use solar ovens to cook food and to heat drinking water to kill bacteria and other harmful organisms.
There are three kinds of solar ovens.The first is a box cooker, It is designed with a special wall that shines or reflects sunlight into the box .Heat gets trapped under a piece of glass or plastic covering the top of the cooker. A box oven is effective for slow cooking of large amonts of food.
The second kind of solar oven is a panel cooker. It includes several flat walls.or panels.that directly reflect the sun’s light onto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much.In Kenya ,for example ,panel cookers are being manufactured for just two dollars.
The third kind of solar oven is a parabolic cooker.It has rounded walls that aim sunlight directly into the bottom of the oven .Food cooks quickly in parabolic ovens .However, these cookers are hard to make.They must be re-aimed often to follow the sun .Parabolic cookers can also cause burns and eye injuries if they are not used correctly.
You can make solar ovens from boxes or heavy paper. They will not catch fire. Paper burns at two hundred thirty-two degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things.

When Mrs．Joseph Groeger died recently in Vienna，Austria，people asked the obvious question,“Why did she live to be 107?” .Answers were provided by a survey conducted among 148 Viennese men and women who had reached the age of 100．Somewhat surprising was the fact that the majority had lived most of their lives in cities．In spite of the city’s image as an unhealthy place，city living often provides benefits that country living can lack．One factor seems to be important to the longevity(長壽)of those interviewed．
This factor is exercise．In the cities it is often faster to walk short distances than to wait for a bus．Even taking public transportation often requires some walking．Smaller apartment houses have no elevators(電梯)，and so people must climb stairs．City people can usually walk to local supermarkets.  Since parking spaces are hard to find，there is often no alternative to walking．
On the other hand，those who live in the country and suburbs do not have to walk every day．In fact，the opposite is often true．To go to school，work，or almost anywhere else，they must ride in cars．
【小題1】The Vienna survey may help to explain _____

A．the complaints of people in apartment houses

America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while — then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.  Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.  Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don’t show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet a friend. We may take days off to act as guides to our foreign friends. The Americans, however, express their welcome usually at homes, but truly can not manage the time to do a great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, warm and real. We will find ourselves treated hospitably.  For the Americans, it is often considered more friendly to invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

1.The writer of this passage must be ______.

A．a(chǎn)n American

B．a(chǎn) Chinese

A．Friendships between Americans usually extend deeply into their families.

3.From the last two paragraphs we can learn that when we arrive in America to visit an American friend, we will probably be ______.

A．warmly welcomed at the airport

B．offered a ride to his home

C．treated hospitably at his home

D．treated to dinner in a restaurant

4.The underlined words  “generous with our time” in Paragraph 3 probably mean ______.

A．strict with time
