With more and more cars come into our families, we are happy that it has greatly improved our life. But unlucky, it has also brought many problems, such as heavy traffic and traffic accidents.

Traffic safety is everybody’s business. We must obey the rules. For examples, we must walk on the sidewalks. When we cross zebra-crossing, stop and look right and left, and then go across fast. Don’t play the football on the road. Beside, we can tell our parents not to drink after we drive, not to run through red lights, not to use cell-phones while driven etc.

We can say cars are coming into our life, but only when everybody thought traffic safety is his or her business can we be safe driving on roads and walk on sidewalks.

    A student's life is never easy. 1. A lot of preparations are needed so you can be sure to go back home with a diploma and a bright future waiting for you. The following are some basic things you need to do before even seizing that passport and boarding on the plane.

●Knowing the country.

You shouldn't bother researching the country's hottest tourist spots or historical places. You won't go there as a tourist, but as a student. It'll be helpful to read the most important points in their history and to read up on their culture.2. You surely don't want to face legal problems, especially if you're away from home.

●Studying their language.

Don't expect that you can graduate abroad without knowing even the basics of the language. Before leaving your home country, take online lessons to at least master some of their words and sentences.3.  Doing this will also prepare you in communicating with those who can't speak English.

● 4.

Check the conversion（兑换）of your money to their local currency, set up your bank account so you can use it there, get an insurance, and find an apartment. The Internet or your intended school will be very helpful in finding an apartment and helping you understand local currency.

Remember, you're not only carrying your own reputation but your country's reputation as well. If you act foolishly, people there might think that all of your country men are foolish as well.5.．

A. Packing your clothes.

B. Preparing for other needs.

C. Most importantly, read about their laws.

D. This will be useful in living and studying there.

E. That would surely be a very bad start for your study abroad program.

F. Going with their trends will keep it from being too obvious that you're a foreigner.

G. And it is even more difficult if you will have to complete your study in a foreign land.

    Big trees are incredibly important ecologically. For a start, they provide food for countless other species and shelter for many animals. With their tall branches in the sun, they capture vast amounts of energy. This allows them to produce massive crops of fruit and flowers that sustain much of the animal life in the forest.

Only a small number of tree species have the genetic ability to grow really big. The biggest are native to North America, but big trees grow all over the globe, from the tropics to the forests of the high latitudes (纬度). To achieve giant size, a tree needs three things: the right place to establish its seedling, good growing conditions and lots of time with low adult death rate. Lose any of these, and you will lose your biggest trees.

In some parts of the world, populations of big trees are dwindling(逐渐变少) because their seedlings cannot survive. In southern India, for instance, an aggressive non-native bush, Lantana camara, is invading the floor of many forests. Lantana grows so thickly that young trees often fail to take root. With no young trees to replace them, it is only a matter of time before most of the big trees disappear.

Without the right growing conditions, trees cannot get really big and there is some evidence to suggest tree growth could slow in a warmer world, particularly in environments that are already warm. Having worked for decades at La Selva Biological Station in Puerto Viejo de Sarapiqui, Costa Rica, David and Deborah Clark and colleagues have shown that tree growth there declines markedly in warmer years. “During the day, their growth shuts down when it gets too warm, and at night they consume more energy because their metabolic (新陈代谢) rate increases,” explains David Clark. With less energy produced in warmer years and more being consumed just to survive, there is even less energy available for growth.

The Clarks’ theory, if correct, means tropical forests would shrink over time. The largest, oldest trees would progressively die off and tend not to be replaced. According to the Clarks, this might cause a destabilization(不稳定) of the climate; as older trees die, forests would release some of their stored carbon into the atmosphere, causing a cycle of further warming, forest shrinkage and carbon emissions.

Besides, big trees face threats from elsewhere.
