Disposing(处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.
During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot as a dumpsite. Residents or trash haulers(垃圾托运者) would transport household rubbish, rotted wood, and old possessions to the site. Periodically(定期的) some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by.
Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.
Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential(住宅区的)neighborhoods. Long-distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is almost nonexistent.
Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.
Recycling efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city's reusable waste.

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different sense, to find and choose their food. A few animals depend on only one of their senses. while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda (大熊猫) eats only one particular type of bamboo (竹子). Other animals eat only one type of food even when given the choice. A kind of white butterfly (蝴蝶) will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet (多样化饮食). The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health, Choosing the right food, therefore, has become an area of study in modern life.We can infer from the text that humans and animals - —.

People in the United States honor their parents with two special days：Mother＇s Day, on the second Sunday in May, and Father＇s Day, on the third Sunday in June．These days are set aside to show love and respect for parents．They raise their children and educate them to be responsible（有责任感的） citizens．They give love and care．These two days make us think about the changing roles of mothers and fathers．More mothers now work outside the home．More fathers must help with child care．
These two special days are celebrated in many different ways．On Mother’s Day people wear carnations．A red one symbolizes a living mother．A white one shows that the mother is dead．Many people attend religious services to honor parents．It is also a day when people whose parents are dead visit the cemetery（墓地）．On these days families get together at home, as well as in restaurants．They often have outdoor barbecues for Father＇s Day．These are days of fun and good feelings and memories．
Another tradition is to give cards and gifts．Children make them in school．Many people make their own presents．These are valued more than the ones bought in stores．It is not the value of the gift that is important, but it is “the thought that counts”．Greeting card stores, florists, candy makers, bakeries, telephone companies, and other stores do a lot of business during these holidays．WhichisNOTareasonforchildrentoshowloveandrespectforparents?

Of all the websites, one that has attracted attention recently is myspace.com. Most of this attention has come from the media and tells every reason why the website should be shut down. The danger of internet predators(窃掠者) is indeed a tough reality, but shutting down the site is not the answer. If myspace.com were shut down, another site would quickly take its place. Therefore, the right way is to teach teens how to use the site safely and educate them about who may be predators and how to avoid them.
The key to staying safe on the Internet is to make sure that your profile(个人资料) is secure. The simplest way is to change the privacy setting on your profile to “private”, which protects your information so that only the people on your friend list can view it. Although this is effective, it is not perfect. Predators can find ways to view your profile if they really want to, whether through hacking(非法侵入) in or figuring out their way onto your friend list. Thus, you should never post too much personal information. Some people actually post their home and school addresses, date of birth, and other personal information, often letting predators know exactly where they will be and when. The safest information is your first name and province. Anything more is basically inviting a predator into your life.
Another big problem is photos. I suggest completely skipping photos and never posting a photo of a friend online without asking permission.
Most importantly, never, under any circumstances, agree to a real-life meeting with anyone you meet online. No matter how well you think you know this person, there are no guarantees that they have told the truth. But you could feel free to chat with people you meet on the site, but just remember that not everyone is who they say they are. Hopefully, the next time you edit your profile, you’ll be more informed about the dangers of Internet predators and take the steps to defend yourself.
Lastly, do not send money to anyone you meet online. A common scam among Internet criminals is to request to pay for “expensive Internet charges” or “unreasonable Internet cafe fees”. While it is indeed true that many countries in Eastern Europe, Asia, Africa and South America do not yet have Internet service readily available in all cities and towns, a sincere friend from one of these countries will be more than happy to pay their own Internet charges. Never, under any circumstances, should you send money to a stranger from another country(or within your own country for that matter) who claims monetary assistance is required to continue their contact with you.Kids can avoid web predators successfully by________.
| A．attracting more public attention |
| B．shutting down the “myspace.com” |
| C．learning different ways to try other sites |
| D．recognizing and getting away from them |
68. We can learn from the text that________.
| A．everybody you meet online isn’t honest and reliable |
| B．it is not acceptable to post a photo of a friend online |
| C．it is not safe to chat with grown-ups on the website |
| D．only you and your friends can view your personal profile |
What does the underlined word “scam” in the last paragraph mean?
| A．A thing that you can have two choices. |
| B．An unpleasant task that tests one’s ability. |
| C．A possibility of something happening. |
| D．An illegal plan for making money. |
What could be the best title of this passage?
| A．Personal Safety. | B．Web Safety for Teens. |
| C．Web Hackers in the past. | D．Predators’ Tricks. |
It is often said that man has become the enemy of our planet. This is no exaggeration(夸张), for reports show that man’s greed has done much to destroy the earth. Man, in his greedy desire for financial growth, has polluted the air, land and water, and has robbed our valuable natural resources. Man’s industrial plants pour out poisonous waste that pollutes the sea and puts life in the sea under the threat of dying out; at the same time, they release alarming amounts of carbon dioxide, chlorofluorocarbons (CFCs) and other pollutants. Small wonder that the air now is much warmer and more impure than ever before.
Of course, this is not just because of man’s greed—it is man’s pressing need as well. For instance, in developing countries, huge financial foreign debts have forced governments to approve the cutting of forests for agriculture or ranching. As a result, forests are cut down just to meet man’s immediate needs.
Perhaps unknowingly，man has changed the make-up of the earth's atmosphere. Scientific studies have shown that CFCs used in refrigerators and industrial cleaners are fast destroying the ozone layer—a protective layer in the atmosphere that protects us against the harmful effects of the sun’s ultraviolet (紫外线)rays. In fact, documented reports have shown a terrible fact that there are “holes” in the ozone layer over the Antarctic. And they appear to be expanding.
Faced with these environmental problems, world leaders have shown deep concern. The UN Environmental Programme (UNEP) has arranged international agreements like the Vienna convention of 1985 and the Montreal Protocol of 1989 to preserve the ozone layer by controlling the production, use and trade of destructive chemicals.
There may be some doubt as to how effectual these agreements may be, given that some countries still maintain an “I-don’t-care” attitude. Their attitude is probably due to their failure to grasp the importance of the problem. Then, there is no doubt that environmental education on an international scale（规模）is greatly needed, so that all countries, great and small—the “haves” and the “have nots”—may realize their responsibilities for our planet.
In the meantime, the UNEP seems to have taken steps in the right direction, and it is hoped that in the not so distant future, all nations of the world will join hands in saving mother earth. Which of the following is a reason for the cutting and burning of forests?
| A．To build houses for more population. | B．To have land for agriculture. |
| C．To export trees to other countries. | D．To build industrial plants. |
The holes in the ozone layer are largely due to________.
| A．man’s research activities | B．the greenhouse effect |
| C．the ultraviolent | D．harmful chemicals |
Why don’t some countries care about the problem of the environment?
| A．They don’t want to put their lives in danger. |
| B．They just don’t know how to solve the problem. |
| C．They haven’t realized the seriousness of the problem. |
| D．They don’t want to break their international commitment. |
66. What is the author’s attitude towards the future of the environment?
| A．Hopeful. | B．Unconcerned | C．Doubtful | D．Objective |
