It is often said that man has become the enemy of our planet. This is no exaggeration(夸張), 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 (紫外線)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（規(guī)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.

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(竊掠者) 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(個人資料) 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.

1.Kids can avoid web predators successfully by________.

A. attracting more public attention

B. shutting down the “myspace.com”

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

3.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.

4.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.

A hobby is an investment of time. It also can be an investment of money and commitment. Many people choose to develop more than one type of hobby.   1.   When it comes to choosing the hobby, consider the following factors.

Hobbies are usually an activity of some sort that brings out a certain skill that you have. When you have a talent like painting or woodworking, it can be easy to determine which hobby suits your skill.   2.   Skill can be developed and challenged as you go along. It is not a necessary requirement. A hobby is fitting because you love it, not because you’re a professional at it.

Some people particularly enjoy taking part in hobbies that they can do in a group with others. It can be a lot more fun to become a member of a hobby group than to sit alone in your basement.    3.   It’s important to share interests and network with other hobby enthusiasts that do what you do.

Hobbies are generally an activity that you undertake because of the joy it brings you. Of course many people have discovered the joy that also comes with a hobby that earns you a living.   __4.  Just make sure you make the choice that fits your lifestyle and personal preference.

  5.   But most of the skilled hobbies like art, building or writing have a series of lessons or tutorials that you can take to further your skills. In some cases it’s a really good idea to take lessons, especially if you are clueless as to where or how to begin. Step by step books for most hobbies can often be found in bookstores as well.

A. However, hobbies don’t have to be skill related.

B. Most hobbies can easily be done within your own home, at your leisure.

C. Look one up or start your own.

D. Read hobby books to learn more about your chosen hobby!

E. Make a list of things that you enjoy or don’t know about.

F. It can be a necessary part of selecting the hobby that is right for you.

G. Whether it’s full time, part time or not at all, you must decide whether your hobby applies to you.
