Article: Having good social relationships -- friends, marriage or children -- may be every bit as important to a healthy life as quitting smoking, losing weight or taking certain medicines. U. S. researchers reported on Tuesday. People with strong social relationships were SO percent less likely to die early than people without such support, the team at Brigham Young University in Utah found. They suggest that the government look at ways to help people keep social relationships as a way of keeping the population healthy. "A lack of social relationships was equal to smoking up to 15 cigarettes a day," psychologist Julianne Holt-Lunstad, who led the study, said in a telephone interview. Her team conducted a study that examined social relationships and their effects on health. They looked at 148 studies that covered more than 308,000 people, published in the Public Library of Science journal PLoS Medicine at www.plosmedicine.org. Having low levels of social relationships was equal to being an alcoholic, was more harmful than not exercising and was twice as harmful as obesity. Social relationships had a bigger effect on early death than getting an injection to prevent pneumonia ,than taking drugs for high blood pressure and far more important than living in air pollution, they found. "I certainly don't want to _ these other risk factors because of course they are very important," Holt-Lunstad said. We need to start taking social relationships just as seriously. " But Holt-Lundstad said there was some evidence that assigning caretakers does not help improve people's health. "Naturally occurring relationships may be different than the support received from someone who is hired for that purpose." she said. Question: What conclusion can we draw from the text? - The support from hired caretakers is more natural. - The love from our family members has better effect. - Air pollution does more harm to people than poor social relationships. - Poor social relationships are the biggest reason for people's early death.
The love from our family members has better effect.

It was always bad and usually foolish, but in the past, the human race managed to live with it. Modern cleverness has changed this. Either man will end the existence of war, or war will end the existence of man. For the present, it is nuclear weapons that cause the most serious danger, but bacteriological or chemical weapons may, before long, offer an even greater threat. If we succeeded in ending the existence of nuclear weapons, our work will not be done. It will never be done until we have succeeded in ending war. To do this, we need to persuade mankind to look up on international problems in a new way not as contests of force, in which the victory goes to the side which is most skillful in killing people, but by settling in accordance with(, , , ) agreed rules of law. It is not easy to change very old mental habits, but this is what must be attempted. There are those who say that the acceptance of this or that ideology would prevent war. I believe this to be a big mistake. All ideologies are based upon dogmatic statements ,which are, at best, doubtful, and at worst, totally false. Their supporters believe in them so deeply that they are willing to go to war in support of them. The movement of world opinion during the past few years has been very largely such as we can welcome. It has become a common place that nuclear war must be avoided. Of course very difficult problems remain in the world, but the spirit in which they are coming nearer to is a better one than it was some years ago. It has begun to be thought, even by the powerful men who decide whether we shall live or die, that negotiations should reach agreements even if both sides do not find these agreements wholly satisfactory. It has begun to be understood that the important struggle nowadays is not between different countries but between man and the atom bomb . Question: This passage implies that war is now _ . - worse than in the past - as bad as in the past - not as dangerous as in the past - as necessary as in the past
worse than in the past

Now new research suggests that some dreams may result from the brain's effort to keep learning, even as we sleep. In a study in Boston, 100 volunteers were trained for an hour on a maze .They tried to find their way through the difficult puzzle as quickly as possible. Then half of the volunteers were allowed to sleep for 90 minutes. The other half stayed awake, reading or relaxing. The ones who slept were asked to describe their dreams when they woke up. After the rest, the volunteers were asked again to solve the maze. Those who hadn't slept showed no improvement or did even worse after the break. Sleepers who didn't report any maze related dreams did better but showed only a little improvement. However, four nap-takers who reported dreaming about the maze showed a surprising improvement. They scored 10 times higher after sleeping and dreaming about the maze. Even though the number of dreamers was small, the researchers noted that the gap in learning between the dreamers and non-dreamers was so wide that the finding was significant . The dreamers had all performed poorly on the test before dreaming about it. That suggests that struggling with a task might be the _ that leads the sleeping brain to focus on it and work on how to deal with it. "It's almost as if your brain is going through everything that happened today,"Dr Stickgold,a scientist at Harvard Medical School, said. "The things you're obsessed with are the ones that your brain forces you to continue to do with." Question: According to the study, which group showed the greatest improvement? - Those who didn't sleep. - Those who slept but didn't dream. - Those who dreamed about the maze while sleeping. - Those who thought about the maze before falling asleep.
Those who dreamed about the maze while sleeping.
