There are new findings that not enough sleep may cause people to gain weight.Researchers say a lack of sleep can produce hormonal changes that increase feelings of hunger. In one study,researchers in the United States examined information on more than 1000 people.The people had taken part in a long-term study of sleep disorders. Some people slept less than five hours a night.They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours.And they had 15 percent less of the hormone leptin.Experts say ghrelin helps make people feel hungry;leptin makes you feel full. The scientists say these hormonal changes may be a cause of obesity in Western societies.They note the combination that limitation is common and is widely available. The results were not affected by how much people exercised.People who are awake longer have more time to burn energy.But the researchers say loss of sleep may increase hunger especially  for high-calorie foods,so people gain weight.It seems that,for survival,the body may be designed to store more fat during times with less sleep. Researchers from Stanford University in California and the University of Wisconsin did the study.They found that the best amount of sleep for weight control is 7.7 hours a night. The Public Library of Science published the findings in its journal Medicine.Internet users can read the full study,free of charge,at plos.org. When you sleep 7.7 hours a night,you will  _  . A) have your ghrelin level rise and leptin level drop B) have your leptin level rise and ghrelin level drop C) have your ghrelin and leptin levels properly balanced D) feel neither hungry nor full

During the next several weeks I went completely to the wolves. I took a tiny tent and set it up on the shore of bay. The big telescope was set up in the mouth of the tent in such a way that I could observe the wolves by day or night. Quite by accident I had pitched (set up) my tent within ten yards of one of the major paths used by the wolves. Shortly after I had taken up residence one of the wolves came back and discovered me and my tent, but he did not stop or hesitate in his pace. Later, one or more wolves used the track past my tent and never did they show the slightest interest in me. I felt uncomfortable at being so totally ignored. The next day I noticed a male wolf make boundary markers by passing water on the rounds of his family lands. Once I had become aware of the strong feeling of property rights which existed among the wolves, I decided to use this knowledge to make them at least recognize my existence. One evening, after they had gone off for their regular nightly hunt I staked out   a property of my own, including a long section of the wolves' path. In order to ensure that my claim would not be overlooked, I made a property mark on stones, dumps of moss, and patches of vegetation with a lot of tea. Before the hunters came back, task was done, and I retired, somewhat exhausted, to observe results. A few minutes later, the leading male appeared. As usual he did not bother to glance at the tent, but when he reached the point where my property line intersected (cut across) the trail  , he stopped as suddenly as if he had run into an invisible wall. Cautiously, he extended his nose and sniffed at one of my marked bushes. After a minute of hesitation he backed away a few yards and sat down. Then, he looked directly at the tent and at me. His glare seemed to become more fierce as I attempted to stare him down. The situation was becoming intolerable. To break the impasse   I turned my back on the wolf. Then quickly and with an air of decision, he turned his attention away from me and began a... Which is TRUE according to the passage? A) The author likes staring matches especially with wolves. B) Staking the land was very easy. C) Wolves can see the estate boundaries clearly with their eyes. D) The author managed to know why the wolves ignore his presence.
