| Many young people can use a computer, but few of them know how to look after it. Remember the following tips when you use a computer. Keep your computer in a cool, dry room. Too much or too little heat is bad for computers. Damp (潮湿) is also bad for them. Most computers work best at a temperature of 5-10 degrees centigrade (摄氏度). Do not let people smoke cigarettes near your computer. Smoke of all kinds is very bad for many parts of the computer and can cause many problems. Do not eat or drink when you are near your computer. Pieces of food or drops of water on the keyboard can also cause many problems. Make sure that the keyboard and the screen are the correct height for you. If they are not correct, you will get backache. Make sure the screen is the correct distance from your eyes. If you wear glasses, make sure these glasses are correct for using with the computer. Some people use a different pair of glasses when they use a computer. Keep your screen clean and do not have it too bright. A dirty screen can hurt your eyes. A very bright screen can also be bad for your eyes. If you can afford one, buy a computer screen. It will be better for you than using the screen of a TV set. Never use any software (软件) that you don"t know whether they are clean or not. You must be careful because some software can bring viruses (病毒) into the computer. If your computer has viruses, it can"t work or even breaks down. | |||

| November 24, 1859 was a special day in London. On the day, many Londoners rushed to a bookstore to buy a book that was just published. The first printing of 1,250 copies sold out on the first day. The popular book was The origin of Species (《物种起源》) by British naturalist Charles Darwin (1809-1882). In the book, Darwin argued that different forms of life could change over time because of natural selection. This means that only those who are best suited to their environment will live and reproduce. Darwin supported his arguments with examples he found during his around-the-world trip in the 1830s. The book laid the foundation of modern biology. It changed how other scientists understood the appearance of life on Earth. A hundred and fifty years later, Darwin"s theory (理论) of natural selection still has great influence in the world of science. But some people have a question: since medicine and modern life have made people healthier, are we still evolving (进化) by natural selection? The answer is yes, according to Stephen Sterns and his team of Yale University researchers. They did a study on 2,238 women in the US. They found that shorter, heavier women have more children then thinner, taller ones. This trend (趋势) runs among their female children and grandchildren. So if this continues, women in 400 years will be about 2cm shorter and a kilo heavier. Sterns" findings are supported by other scientists. For example, John Hawks at the University of Wisconsin, US and his team believe they have found nearly 2,000 gene variations (基因变异) in modern humans. Those variations allow people to drink milk, fight disease and improve brain development. | |||
| 1. Was The origin of Species a popular book? 2. When was the book published? 3. What does natural selection mean? 4. Why does the writer introduce Sterns" findings in the passage? 5. Why is Darwin"s theory of natural selection important? | |||
