I'm taking a test and have to guess the right answer to the question after the article. Article: Teens who become addicted to their cellphones may be placing their health at risk by harming their ability to sleep well,a new Swedish study suggests. "The message is that teenagers who use their cellphones excessively are much more stressed, much more restless, much more tired, and have a great tendency to develop sleep deprivation as a result of their calling habits, " said the study author Dr. Gaby Bader. He focused on the experiences of 21 healthy Swedish boys and girls between the ages of 14 and 20. The teens kept what the authors described as "regular working/studying hours" and were not previously diagnosed with any particular sleep irregularity. He observed that the above-15 call group kept more irregular sleeping hours than the lower-use group,had more difficulty falling asleep,more difficulty waking up,and experienced more sleep disruptions . Bader said that among young people,a ly recent technological invention like the cellphone has quickly become existed nearly everywhere,giving rise to considerable pressure to keep in touch. And this pressure can develop into an addiction,with serious negative results for teenager health. "We see more and more people--especially the young generation-- who grew up with these kinds of items and gadgets in their hands," Bader said. "And they become dependent on the technology. So,we have to teach young people to be structured. To know when to have the cellphone on,and when to switch it off. To avoid becoming the slave of technology,instead of the master. " Dr. Mary Carskadon expressed little surprise with the finding. " Interpersonal contact is one of the things that's best at keeping us awake," she observed. "And so,a young person receiving cellphone texts or phone calls is going to have more deep disturbances. And they are going to be tired and restless,and probably,as a result,going to use more stimulants .And judgment is not always the best in our teenage years. So, that's where I think parental attention to this issue may be useful. " Question: According to Dr. Mary Carskadon,how to deal with the problem? Options: A: Teenagers should judge how to use their phones. B: Teenagers should reduce their interpersonal contact. C: Teenagers should switch their phones off. D: Parents should give more attention to children's use of phones.

I'm taking a test and have to guess the right answer to the question after the article. Article: Most of the people who appear most often and most gloriously in the history books are great conquerors and generals and soldiers, whereas the people who really helped civilization forward are often never mentioned at all. We do not know who first set a broken leg, or launched a seaworthy boat, or calculated the length of the year, or manured a field; but we know all about the killers and destroyers. People think a great deal of them, so much so that on all the highest pillars in the great cities of the world you will find the figure of a conqueror or a general or a soldier. And I think most people believe that the greatest countries are those that have beaten in battle the greatest number of other countries and ruled over them as conquerors. It is just possible they are, but they are not the most civilized. Animals fight; so do savages ; hence to be good at fighting is to be good in the way in which an animal or a savage is good, but it is not to be civilized. Even being good at getting other people to fight for you and telling them how to do it most efficiently -this, after all, is what conquerors and generals have done -is not being civilized. People fight to settle quarrels. Fighting means killing, and civilized peoples ought to be able to find some way of settling their disputes other than by seeing which side can kill off the greater number of the other side, and then saying that that side which has killed most has won. And it not only has won, but, because it has won, has been in the right. For that is what going to war means; it means saying that might is right. That is what the story of mankind has on the whole been like. Even our own age has fought the two greatest wars in history, in which millions of people were killed or disabled. And while today it is true that people do not fight and kill each other in the streets -while, that is to say, we have got to the stage of keeping the rules and behaving properly to each other in daily life - nations and countries have not learnt to do this... Question: In the opening sentence the author indicates that _ . Options: A: conquerors, generals and soldiers should not be mentioned in history books. B: history books focus more on those who helped civilization forward. C: those who truly helped civilization forward is rarely mentioned in history books. D: most history books were written by conquerors, generals and soldiers.

I'm taking a test and have to guess the right answer to the question after the article. Article: On Thursday afternoon Mrs. Clarke, dressed for going out, took her handbag with her money and her key in it, pulled the door behind her to lock it and went to the over 60s Club. She always went there on Thursdays. It was a nice outing for an old woman who lived alone. At six o'clock she came home, let herself in and at once smelt cigarette smoke. Cigarette smoke in her house? How? How? Had someone got in? She checked the back door and the windows. All were locked or fastened, as usual. There was no sign of forced entry. Over a cup of tea she wondered whether someone might have a key that fitted her front door -- " _ " perhaps. So she stayed at home the following Thursday. Nothing happened. Was anyone watching her movements? On the Thursday after that she went out at her usual time, dressed as usual, but she didn't go to the club. Instead she took a short cut home again, letting herself in through her garden and the back door. She settled down to wait. It was just after four o'clock when the front door bell rang. Mrs. Clarke was making a cup of tea at the time. The bell rang again, and then she heard her letter-box being pushed open. With the kettle of boiling water in her hand, she moved quietly towards the front door. A long piece of wire appeared through the letter-box, and then a hand. The wire turned and caught around the handle on the door-lock. Mrs. Clarke raised the kettle and poured the water over the hand. There was a shout outside, and the skin seemed to drop off the fingers like a glove. The wire fell to the floor, the hand was pulled back, and Mrs. Clarke heard the sound of running feet. Question: The lock on the front door was one which _ . Options: A: needed a piece of wire to open it B: could be opened from inside without a key C: couldn't be opened without a key D: used a handle instead of a key
