Personal computers and the Internet give people new choices about how to spend their time. Some may use this freedom to share less time with certain friends or family members, but new technology will also let them stay in closer touch with those they care most about. I know this from personal experience. E-mail makes it easy to work at home, which is where I now spend most weekends and evenings. My working hours aren't necessarily much shorter than they once were but I spend fewer of them at the office. This lets me share more time with my young daughter than I might have if she'd been born before electronic mail became such a practical tool. The Internet also makes it easy to share thoughts with a group of friends. Say you do something fun see a great movie perhaps-and there are four or five friends who might want to hear about it. If you call each one, you may tire of telling the story. With E-mail, you just write one note about your experience, at your convenience, and address it to all the friends you think might be interested. They can read your message when they have time, and read only as much as they want to. They can reply at their convenience, and you can read what they have to say at your convenience. E-mail is also an inexpensive way stay in close touch with people who live far away. More than a few parents use E-mail to keep in touch, even daily touch, with their children off at college. We just have to keep in mind that computers and the Internet offer another way of staying in touch. They don't take the place of any of the old ways. According to the writer, E-mail has an obvious advantage over the telephone because the former helps one _ . A) reach a group of people at one time conveniently B) keep one's communication as personal as possible C) pass on much more information than the later D) get in touch with one's friends faster than the later

The food we eat seems to have profound effects on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that 80 percent of all human illness are connected with diet and 40 percent of cancer is connected with the diet. Therefore, that food is connected with illness is not a new discovery. In 1940's scientists realized that nitrates , which are often used to keep color1 of meat, and other additives caused cancer. However these additives remain in our food and it becomes more difficult to know which additives are helpful or harmful. Farmers sometimes give drugs to animals not because the animals are ill but because they want to sell the animals at higher prices. For example, farmers try hard to make animals grow big so that they can sell the big animals for more money. Although the Food and Drug Administration has tried again and again to control farmers to do so, farmers go on doing this. Which of the following statements is NOT true? A) Drugs are always given to animals for medical reasons. B) Some additives in our food are added not only to the food but also to the animal. C) Scientists knew that some additives are harmful to people over seventy years ago. D) Food may cause 40 percent of cancer in the world.

Q: The English language is changing fast, thanks to the rapid progress of technology. We all have a rapid choice: we can either bury our heads in the sand and spend the rest of our lives wishing Shakespeare were alive and well. Or we can embrace the new English, and enter into the spirit of the Internet age called Weblish. "You can't avoid it, for the simple reason that whenever a new variety of language comes along, it inevitably impacts on the language as a whole ." Says Dr. David Crystal, honorary professor of linguistics at the University of Wales in Bangor, whose book "Language and the Internet" has just been published. The trouble with keeping up with the new English is not so much that there are so many new words but that the old words no longer mean what we thought they did. In the past, if someone said they did not have Windows, you would have to suppose they lived in a cave. These days, it is probably because they use a Mac(which is a computer, not a rain coat). Spam is as disliked as it ever was, but whereas it once meant an unappetizing canned meat. It now stands for unwanted "junk" email. Spellings are changing, too. Not only is text-messaging playing "hvc wth vrbs" (havoc with verbs), but the conventions of email communication place little emphasis on "perfect speaking". Weblish loves to see nouns happily become verbs ("please bookmark this site"), and verbs become nouns ("Send me the download"). Verbs and prepositions are regularly thrown together to become new nouns or adjectives (dial-up, Logon, Print-on, Pull-down, upload), while others are created from simply pairing nouns: Cyberspace, Etl, emit Internet, hyperlink, metatag, netspeak. The author thinks the main difficulty for people in keeping up with Weblish is that_. A) old words take on new meanings B) there are so many new words Ks5u C) the technology is changing too fast D) Weblish words are full of spelling mistakes

We have a strange and strong belief in the idea of perfection. Driven by our culture, we struggle for an unattainable ideal: If I have the perfect parents, perfect grades, perfect..., then I would be happy. We seek what we can't have without remembering that we don't actually need to be perfect. Imperfection allows us to be human. Parents, teachers and other high-achieving peers will have us believe that we must be perfect if we wish to remain competitive. However, what job or school requires you to develop a cure for some form of cancer by the age of 18? Although these grades would be admirable achievements, are they worth losing sleep over? We feel like we need the perfect grades to get into the perfect college that will provide us with the perfect education necessary to obtain the perfect job. Making use of our thirst for perfection, the whole college and career industries have emerged claiming to help us reach our goals. Truth is, you only need to be good enough to get into the conversation. It is what you do afterwards that sets you apart. Focus more on your passions. Don't worry about anything secondary to your passions. You don't become an expert at anything if you spent your time trying to succeed in everything you do. You only become an expert when you devote your time to that one project that truly brings you joy. As members of this society, we have a responsibility to be excellent in what we do, not perfect. Although perfection can be a goal, it should not be the only goal. We only have 24 hours in a day and seven days in a week. Thus, we need to plan what we want to do and cut out the activities we cannot do. With everything, though, make sure you're doing enough. Pursuing your passions is not enough of a reason to completely give up on everything else. Try as hard as you can and let your future worry about itself. Worry about your task at hand and you will be successful in achieving your dreams. Most of all, remember that you're going to be okay. According to the author, we should _ . A) see becoming perfect as our responsibility B) deal with what we hope to do first C) set a goal of perfection in our life D) worry about our future dreams
