How can you find out what is going on inside a person' s body without opening the patient up? Regular X-rays can show a lot. CAT scans can show even more. They can give three-dimensional view of body organs . What is a CAT scan? CAT stands for Computerized Axial Tomography(X). It is a special X-ray machine that gets a 360 - degree picture of a small area of a patient's body. Doctors use X-rays to study and examine diseases and injuries within the body. X-rays can find foreign objects inside the body or to take pictures of some organs inside if special things as dyes or special liquids are added to the organs to be X-rayed. A CAT scanner, however, uses a beam of X-rays to give a cross-sectional view of a particular part of the body. A fine beam of X-rays is scanned across the body and circled around the patient from many different angles . A computer analyzes the information from each angle and produces a clear cross-sectional picture on the screen. This picture is then photographed for later use. Several cross-sections, taken one after another, can give a clear "photo" of the entire body or of any body organs. The newest CAT scanners can even give a clear picture of active, moving organs just as a fast-action camera can "stop the action" giving clear pictures of what appear only mistily to the eye. And because of the 360 - degree pictures, CAT scans show 3-dimensional views of organs in a manner that was once only seen during surgery or autopsy (examining a dead body). The best title of this passage might be _ . A) Modern X-ray B) Three-dimensional View C) Fast - moving Camera D) CAT Scan

The Colonel asks Ashenden a good many questions and then suggested that he had particular qualifications for the Secret Service. Ashenden knew several European languages and the fact that he was a writer provided excellent cover: on the pretext that he was writing a book he could, without attracting attention, visit any neutral country. It was while they were discussing this point that the Colonel said, "You know you might get material that would be very useful to you in your work. I'll tell you an incident that occurred only recently. Very dramatic. A foreign government minister went down to a Mediterranean resort to recover from a cold and he had some very important documents with him that he kept in a dispatch case . A day or two after he arrived, he picked up a beautiful blonde at some restaurant or other, and he got very friendly with her. He took her back to his hotel, and when he came to himself in the morning, the lady and the dispatch-case had disappeared. They had one or two drinks up in his room and his theory is that when his back was turned the woman slipped a drug in his glass. "Do you mean to say that happened the other day?" said Ashenden. "The week before last." "Impossible," cried Ashenden. "Why! We've been putting that incident on the stage for sixty years, we've written it in a thousand novels. Do you mean to say that life has only just caught up with us?" "Well, I can guarantee the truth of the story." said the Colonel, "And believe me, the government has been put to no end of trouble by the loss of the documents." "Well sir, if you can't do better than that in the Secret Service," sighed Ashenden, " I'm afraid that as a source of inspiration to the writer of fiction, it's washout." Ashenden cried 'Impossible' after hearing the Colonel's story because he thought _ . A) it could not possibly happen B) it was too embarrassing C) it was too close to fiction D) it was too recent

Ques: There are times when nothing seems to be working in our favor. We may use complaining as a coping mechanism (,) when we are truly unhappy. However, there are many times when we don't try our best and just want things to work our way. We may try to cover our faults by complaining about the unfairness of it all. These are expressive complaints where the complainer just wants to let out his/her anger or frustration, with no real intention of solving the problem. The complainer expects pity and recognition from the listeners although the results often disappoint him/her. Sometimes, we use complaints as a conversation starter. Conversations that start with a complaint often have a domino effect. It may cause the listener to include his/her complaints in the conversation as well, which makes you think that you are not the only one facing problems. However, your good feeling won't last long as long as you are always focusing on the negative. When complaining becomes a habit, you complain to anyone that comes around. Negativity that comes from complaining kills creativity and innovation . Habitual complainers are less likely to come up with new ideas, as they are busy finding faults and discourage others from trying new things by making them feel that they won't work. When you spend time with people who constantly complain, you are likely to view things in a negative light. This will make things worse. This can affect the way you perceive your own situation, and even the people around you. Though expressing your feelings may momentarily improve your state of mind, it could sometimes have a bad effect on the listener's state of mind. A recent study has shown that at social gatherings while people who are unhappy may join you when you play the victim at the beginning, the majority would start avoiding you because of your negativity. Why do people who don't try their best often complain? A) They want to get others' pity. B) It is the best way to let out their anger. C) They try to find an excuse for their faults. D) They hope to get a solution to their problems.
Ans: C
A group of eight public high school students in Massachusetts, aged l5 to l7,designed and ran their own school within a school. They named their practice the Independent Project. They represented the usual range: two were close to dropping out before they started the project,while others were honors students. Their guidance teacher was their adviser, consulting with them when the group encountered difficulties. Though they sought advice from English,math and science teachers, they were responsible for monitoring one another's work and giving one another feedback. There were no grades, but at the end of the term,the students wrote evaluations of their classmates. The students also designed their own course. In addition to some regular courses,they each took on an 'individual project',learning to play the piano or to cook,writing a novel or making a video about domestic violence. At the end of the term,they performed their new skills in front of the entire school. The last part of their self - designed course was to do a 'collective project' that had social significance. Because they felt the whole experience had been so life - changing,they ended up making a film showing how other students could start and run their own schools. The project was a success. After returning to their traditional study,the students have high motivation and are doing well. One student who had failed all of his previous math courses spent three weeks teaching the others about probability. The lesson learned here is that if students are given the opportunity to take control or contribute significantly to their own learning they will become more accomplished,more engaged and more knowledgeable. The students in the project are remarkable because they demonstrate the kinds of learning and personal growth that are possible when teenagers feel ownership of their high school experience,learn things that matter to them and learn together. The project made the students outstanding because _ . A) they are unusually talented B) they have better backgrounds C) they have supportive teachers D) they are owners of their education
