Question: Can you imagine that you can save your own life during a heart attack by coughing ? Let's see how... A heart attack can happen to anyone. Let's say it's 4:17 p.m. and you're driving home (alone of course) after an unusually hard day on the job. Not only was the workload extremely heavy, you also had a disagreement with your boss, and no matter how hard you tried, he just wouldn't see your side of the situation. You're really upset and the more you think about it, the more nervous you become. All of a sudden you start experiencing severe pain in your chest that starts to spread out into your arm and up into your . You are only about five miles from the hospital nearest your home, unfortunately you don't know if you'll be able to make it that far. What can you do? You've been trained in CPR but the guy who taught the course didn't tell you how to perform it on yourself. Since many people are alone when they suffer a heart attack, this article seems in order. Without help the person whose heart stops beating properly and who begins to feel has only about 10 seconds left before losing consciousness. However, these victims can help themselves by coughing repeatedly and very powerfully. A deep breath should be taken before each cough, and the cough must be deep and last long, as when producing from deep inside the chest. A breath and a cough must be repeated about every two seconds without stopping until help arrives, or until the heart is felt to be beating normally again. Deep breaths get oxygen into the and coughing movements squeeze the heart and keep the blood circulating. The squeezing pressure on the heart also helps it regain normal rhythm . In this way, heart attack victims can get to a phone and, between breaths, call for help. Now, do you understand the whole matter? Tell as many other people as possible about this. It could save their lives! According to the passage, CPR is most probably something done to _ . A) regain someone's breath and heart beat B) help someone treat a heart attack by himself C) teach people how to stay in good state D) train people how to stay calm when facing dangers
Answer: A

Question: For better eyesight, doctors advise limiting the hours of screen time and encourage having enough eye resting time. However, another study shows that sitting in front of computer or TV screens for long hours is not the only reason formyopia . An Australian research team studied young children in Sydney and Singapore to find the reasons for myopia. The research team found that theprevalence of myopia among children in Sydney was lower than children in Singapore, even though they spent more time in front of computer and TV screens. The major finding is that children in Sydney spend longer hours on outdoor activities than those in Singapore. Indoor and outdoor sports activities both make the eyes focus on more distant objects, which prevents the eyes from changing shape. But outdoor activities may better help avoid myopia than indoor sports activities. Jane Gwiazda, who does research in sight problems, says: "Natural light is good for eye growth. And extra vitamin D from the sun might contribute to eye growth." Many doctors suggest that every child get its first eye test done when he/she is about two and half years old, and even if his/her sight seems perfect. It is necessary for myopic children to wear glasses to prevent headaches, trouble reading or injuries. It is also important that schools invite doctors to test their students' eyes. If that is not possible, school teachers should at least encourage parents and children to have regular eye examinations and wear glasses. And parents should remember not only to limit the total screen time for their children, but also to encourage them to spend time outdoors. Why are there fewer children with myopia in Sydney than in Singapore ? A) Because Sydney children watch less TV. B) Because Sydney children have more eye resting time. C) Because Sydney children use computers less. D) Because Sydney children do more outdoor sports.
Answer: D

Question: Whether the eyes are "the windows of the soul" is debatable;that they are intensely important in interpersonal communication is a fact.During the first two months of a baby's life,the stimulus that produces a smile is a pair of eyes.The eyes need not be real:a mask with two dots will produce a smile.Significantly,a real human face with eyes covered will not motivate a smile,nor will the sight of only one eye when the face is presented in profile .This attraction to eyes as opposed to the nose or mouth continues as the baby matures.In one study,when American four--year--olds were asked to draw people,75 percent of them drew people with mouths,but 99 percent of them drew people with eyes. In Japan.however,where babies are carried on their mother's back,they do not acquire as much attachment to eyes as they do in other cultures.As a result,Japanese adults make little use of the face either to encode (...) or decode meaning.In fact,Argyle reveals that the "proper place to focus one's gaze during a conversation in Japan is on the neck of one's conversation partner." The role of eye contact in a conversational exchange between two Americans is well defined:speakers make contact with the eyes of their listener for about one second,then dance away as they talk;in a few moments they re-establish eye contact with the listener or reassure themselves that their audience is still attentive,then shift their gaze away once more.Listeners,meanwhile,keep their eyes on the face of the speaker,allowing themselves to glance away only briefly.It is important that they be looking at the speaker at the precise moment when the speaker reestablishes eye contact:if they are not looking,the speaker assumes that they are disinterested and either will pause until eye contact is resumed or will stop the conversation.Just how critical this eye contacting is to the maintenance of conversational flow becomes clear when two speakers are wearing dark glasses:there may be a sort of traffic jam of words caused by interruption,false... The author is convinced that the eyes are _ . A) of extreme importance in expressing feelings and exchanging ideas B) something through which one can see a person's inner world C) of considerable significance in making conversations interesting D) something the value of which is largely a matter of long debate
