Read the article and select the best answer. Article: Laughter healing benefits and healing with laughter have become synonymous with Norman Cousins, the man who laughed himself to wellness. Norman Cousins was the editor of SaturdayReviewfor over 30 years. His story began in 1964, when doctors found that the connective tissue in his spine was becoming worse, which is a condition known as Ankylosing Spondylitis . The doctors, one of whom was a close friend of Cousins, said that his chance of survival was approximately 1 in 500. He read about the theory that negative emotions do harm to the body, so he thought that if negative emotions were damaging to health, then positive emotions should improve health. Faced with the real possibility of his approaching death, Cousins thought long and hard and eventually did three things completely contrary to medical opinion. First he began his own research on all of the various drugs he was on. He discovered that his condition was removing Vitamin C from his body and, based on Cousins' personal research, doctors agreed to take him off several of the drugs he was on and inject him with large doses of this supplement , as Cousins felt this may be his last hope. Secondly, Cousins made a decision to check out of the hospital and into a hotel room. The third thing Cousins did was get a movie projector and a large supply of funny films. On his first night in the hotel Cousins found that he laughed so hard at the films that he was able to stimulate chemicals in his body that allowed him several hours of pain-free sleep. When the pain returned he would simply turn the projector back on and the laughter would help sleep, and he was able to measure the changes in his body by measuring his blood sedimentation rate , and found that this rate dropped by at least 5 points each time he watched one of these videos. The treatment proved to be so effective that in very little time Cousins was off all painkillers and sleeping pills. He found that the laughter relieved the pain and helped him sleep. He returned to work and wrote about his... Question: Which of the following can be the title for the passage? Options: A: Norman Cousins and laughter therapy B: How to fight against diseases C: New discovery on laughter D: Laugh to relieve the pain

Read the article and select the best answer. Article: Even with the multimedia excitement of the web. Electronic Mail, email, is the most frequently used application of the Internet. Many people who have a chance to use the Internet at school, home, and work. They use the Internet for no other purposes than to send or receive emails. It's all very easy. You prepare the message, log onto the Internet, and send it. The message first goes to your Internet Service Provider's mail server, which in turn sends it to the recipient's mail server. On the way your message may go through several servers, each reading the name in order to send it to the right server. The message then remains in the recipient's mail email server until he requests it by "checking his mail". The benefits of emails are obvious: mostly it's quick. Also, many people feel that the rules for regular mails don't apply to email, making it less formal, which in turn make email easier to write and send. It's not just friends and coworkers that are receiving emails. Wherever you look, the Web is providing email addresses. This has made communication between strangers easier than ever. You can read an interesting article online and immediately send the author an email. Anyone who posts his email address on a Web page is saying he wants to receive email. There are places you can go if you don't know someone's email address. Check out Bigfoot, the Internet Address Finder, or Netscape's Email Directories for more information. Email is one of the services offered by your Internet Service Provider--a service that you're applying for every month. Question: The passage is about _ . Options: A: the multimedia excitement B: different websites C: email D: mail server

Ques: Read the article and select the best answer. Article: Nowadays, there is a heated debate on whether pollutants should be cleaned in the air. Cleaning up the air, while good for our lungs, could make global warming worse. And the pollutants still go up around the air, along with carbon dioxide. These pollutants are called aerosols and they include soot as well as mixtures of nitrogen and sulfur and other stuff into the air. Natalie Mahowald, a climate researcher at Cornell University, says so far, scientists have mostly tried to understand what those aerosols do while they're actually in the air. "There are so many different kinds of aerosols," she says. "Some warm and some cool. But in fact, humans are giving out a lot of extra aerosols, and they tend to cool for the most part." The aerosols reflect sunlight back into space, or keep us cool. But it turns out that's not all they do. These aerosols also influence how much carbon dioxide gets drawn out of the air by plants on land and in the sea. "They can add nutrients, for example, to the oceans or to the land," Mahowald says. "But also while they're in the atmosphere they can change the climate, and thus that also can influence the amount of carbon, the land or the ocean can take up. So there are quite a few different ways that aerosols can act on each other." Mahowald's results suggest that reducing those pollutants could be an even bigger problem than realized, when you consider that aerosols help remove carbon dioxide from the air by encouraging plant growth. Hard numbers on this effect are highly uncertain at the moment, but this could turn out to be quite significant. And studying it is not easy because the effects aren't well understood. For example, nitrogen can be a fertilizer , but it can stop plant growing when nitrogen comes out of the air in acid form. Right now it seems like we're much more likely to clean up aerosol pollution, while increasing the amount of carbon dioxide in the air. So scientists, unfortunately, may have a chance to see whether this experiment on our planet should continue or not. Question: Why is it important for scientists to get accurate numbers according to the passage? Options: A: Scientists have a chance to research them. B: They can bring scientists much more benefit. C: Scientists can protect the earth from being polluted D: They can help scientists understand the effects better.
