I'm taking a test and have to guess the right answer to the question after the article. Article: Once upon a time, people wrote letters mostly with pen and paper. But the Internet has changed all that. Among computer users today, between 50 and 90 percent of written letters take place through e-mail. That's much different from the days when everyone relied on "snail mail" . More and more new e-mail users are asking, "How can I write better e-mail message?" Here are six tips for you. (1) Who are you writing to? Who are you writing to? A friend, a classmate, a teacher or a boss? Be sure the tone of your e-mail message is right for the receiver. Using slang or abbreviations may be all right for your friends. But business letters should use full names and complete sentences. (2) Be direct. Readers of e-mail have little patience. Say what you want to say directly. (3) Use short sentences. E-mail is quicker and more convenient than snail mail. It's also much easier to throw away. Don't use long sentences. Make your sentences short and clear. (4) Give enough details . A terrible e-mail message reads like this: "Did you get my e-mail?" Someone reading this will wonder, "Which e-mail? Sent when? About what?" Today's e-mail users sometimes get many messages every day, so be sure your messages have enough details to be understood. (5) Use the subject line well Readers see what's in the subject line of your message before anything else. Don't say "Hi, from Wang Peng"------ they can see who sent the message from the address. A short, direct explanation of the content of your message will get you a faster answer. (6) Don't be too slow to answer. Remember that in the world of e-mail, things happen fast. If you take longer than a week to answer someone's message, it may be too late. Question: Which of the following subject lines is the best? Options: A: Hello from Ann B: Hello. I sent you an e-mail C: About math exam D: You'll be pleased to get my e-mail

I'm taking a test and have to guess the right answer to the question after the article. Article: Getting close to active or erupting volcanoes can be dangerous. But for Michael Rampino, it's all in a day's work. Rampino is a volcanologist, a scientist who studies volcanoes and how they affect our planet. Rampino has been close to red-hot lava flows in Hawaii and explosive volcanoes in Indonesia. He knows when to get close to an active volcano and when to back away. Rampino wasn't always a volcanologist. He worked for NASA for seven years. He studied rocks until he began to research climate change and the effects that volcanoes have on climate. He became interested in the subject. "Once I started working with volcanoes," Rampino said, "I was _ ." Rampino is a professor at New York University. As part of his job, he travels to areas where volcanoes have been active. "Active" means they have erupted within the past few centuries and probably will erupt again. Rampino studies the deposits of ash and other materials from the eruptions. The ash may hold clues to what happened to the Earth in the distant past. It may also help scientists predict what could happen to Earth's climate in the future. Rampino doesn't work alone. He works with a team of scientists who use computers to stimulate the effects volcanoes have on Earth's atmosphere. Being a volcanologist may be hard work, but it's also fun. "It's cool traveling the world studying volcanoes," Rampino says. When he talks to students about his work, he tells them that his goal is "to understand the events that have shaped Earth's history." Question: In which part of a newspaper could we find this text? Options: A: Climate. B: History. C: People. D: Business.

I'm taking a test and have to guess the right answer to the question after the article. Article: Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu may make a difference in how long the misery lasts. The American Lung Association (ALA) has issued new guidelines on combating colds and the flu , and one of the keys is being able to quickly tell the two apart. That's because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come. The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses - flu A, B and C. There is no cure for either illness , but the flu can be prevented by the flu vaccine, which is, for most people, the best way to fight the flu, according to the ALA. But if the flu does strike, quick action can help. Although the flu and common cold have many similarities , there are some obvious signs to look for. Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms. The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms. Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome ,a rare but serious condition of the liver and central nervous system. There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one. Question: If children have flu-like symptoms, their parents _ . Options: A: are advised not to give them aspirin B: should watch out for signs of Reye syndrome C: are encouraged to take them to hospital for vaccination D: should prevent them from mixing with people running a fever
