Article: Heavy rains have caused disasters across China this summer, bringing the worst landslides in decades. The most deadly disaster happened on August 8 when a big landslide hit Zhouqu County in Gansu province, killing at least 1,407 people. On August 18, landslides hit Gongshan, a town in northwestern Yunnan. At least 38 people were killed and 54 are missing. Heavy rains also caused landslides in several counties in Sichuan province. People were forced to evacuate to safe places. Landslides and devastation Landslides take place when dirt and rocks slide down a slope together. Sometimes these landslides are small, and hardly noticeable. Other times however, they can be massive, involving the entire side of a mountain. Landslides can be caused by a number of different things. Often rain, which adds weight to the side of a slope, can cause one. Other times they might be caused by erosion .When a stream slowly removes the base of a slope, it weakens the entire side of the mountain. As a slide moves down a mountain slope, it can pick up great speed and energy. Some slides travel at a speed of 300km an hour. The resulting winds can be so powerful that they are known to strip the leaves off surrounding trees. Earthquakes and landslides Some experts think the landslides in Sichuan were related to the magnitude-8.0 Wenchuan earthquake on May 12, 2008. The quake has caused a change in the structure of the Earth's surface, making it more likely that land will slide in the rain, according to geologist Xu Qiang of the Chengdu University of Technology. Landslides pose threats to 140 cities and towns in the country, one quarter of which are in Sichuan, said Wei Fangqiang, a researcher with the Chinese Academy of Sciences. Landslide prevention If you want to avoid being a landslide victim, the easiest thing to do is avoid living on slopes or close to mountains. If you live in a landslide-threatened area, try not to water the slopes if possible. If there are large rocks on the slopes above your house, remove them so that they don't cause damage if they fall. It might also be helpful to plant trees on the slopes. Over time, the tree roots may make the soil firmer.

Article: Students often want to practice their English outside class. One of the best ways to practice your English is to speak to a foreigner. You may ask, "Is it okay to try to talk to foreigners I see in the street?" The answer is yes and no, but probably no! If you see a foreigner who looks lost, it is polite to ask him, "May I help you?" But, otherwise, you should probably let them get on with their business. Situations, however, do exist where it is quite all right to talk to foreigners. If a foreigner enters your school, classroom, office, shop or restaurant, for instance, feel free to ask him (for example): -- What is your name? -- Where do you come from? -- What do you think of Beijing? -- How long will you stay in Beijing? There are also situations where it's okay to talk to foreigners in public places. If you see a foreigner alone in a restaurant, bar or coffee shop, it may be appropriate to ask him or her: -- Is this seat free? -- Do you mind if I talk to you in English? You can probably help them if they are new in China and if they are alone, you may be able to make them feel more welcome. After a few such questions, you should know whether this person wants to talk to you or not. If they ask you similar questions, or if they give long, informative answers, you're in luck. If not, then give them their privacy. Talking to strangers is fun if you choose the right time and place.

Article: The average person learns most of the 30 000~40 000 words whose meanings he or she recognizes by hearing them or getting familiar with them in the context or simply absorbing them without conscious effort. The best way to build a good vocabulary, therefore, is to read a great deal and to participate in a lot of good talks. There are relatively few words that we learn permanently by purposefully referring to dictionaries or keeping word lists. However, even those extra few are of value, and no one will make a mistake by working on developing a larger vocabulary. Here are some suggestions of how to do it. Read plenty of good books. When you come across a new word, or a new meaning of an old word, stop and see if you can understand it from its context. If you can't, and if you can manage without interrupting the thought of the book too much, look it up in a dictionary or ask somebody and then repeat its meaning to yourself a couple of times. If you are really conscientious , write the word and its meaning in a personal vocabulary list - preferably using it in a sentence, or you can keep a special vocabulary notebook. Go over the list from time to time. Further, try to use a new word in writing or conversation a few times over the next several days. Listen to good talks and be alert to new words you hear or to new meanings of words you already know. Then treat them just as you treat the new words you read. Learn and be alert to the parts of words: prefixes, suffixes and roots. Knowing _ enables you to make intelligent guesses about the meanings of words. If you are studying a foreign language, be alert to words in that language which relate to words in English. English has inherited or borrowed much of its vocabulary of 500 000~600 000 words from Latin, Greek, French, Spanish and German.
