英语期末考试翻译句子

Unit1 A new study shows that dogs can detect if someone has cancer just by sniffing the person’s breath. Ordinary household dogs with only a few weeks of basic training learn to accurately distinguish between breath samples of lung- and breast-cancer patients and healthy subjects.One expert, who led the research, said, “Our study provides compelling evidence that cancers hidden beneath the skin can be detected simply by (dogs’) examining the odors of a person’s breath.” Early detection of cancers greatly improves a patient’s survival chances, and researchers hope that man’s best friend, the dog, can become an important tool in early screening. Unit 2
A research team recently replicated a bacterium’s genetic structure entirely from l aboratory chemicals, moving one step closer to creating the world’s first artificial organism. The researchers said, “It’s the second step of a three-step process to create a synthetic organism. But the final step could prove far more difficult.” Nonetheless, the research is pushing forward at a rapid pace. Last June, the team revealed details of an experiment in which researchers inserted the DNA of one species of bacterium into the cells of another. That process almost magically booted up the inserted genome. The research team hopes to use a similar trick to boot up the artificially created genome, so as to create a man-made living organism.
Unit 3
In recent years, the psychologists from many countries banded together to do a research which indicated that continued income growth could make people apply themselves to an ongoing consumption race rather than promote overall happiness. Everyone has to spend more and more money in order to maintain a constant level of happiness. This is because our vanity and jealousy are functioning . The way to sort out them out is to cultivate the noble sentiment of being considerate and serving the society. People shouldn’t pin all their hopes on money. Instead , friends, family and work are also playing a very improtant role . Therefore, hapiness is not an inborn trait, but a talent which everyone can learn.
Unit 4 I used to feel excited at teaching my students the elegant economic theories that could supposedly cure societal problems of all types. But what is the good of all my complex theories when people were dying of starvation on the sidewalks and porches across from my lecture hall? My lessons were like the American movies where the good guys always win. But when I emerged from the comfort of the classroom, I was faced with the reality of the city streets. Here good guys were mercilessly beaten and trampled. Daily life ws getting worse, and the poor were growing even poorer.
Unit 5
No one thought that shy little Einstein would grow up to a prominent scientist. He was slow in learning to speak, and he often paused to consider what he would say during a conversation.In school, Albert Einstein was singled out by his teachers as a troublesome child because he liked to ask difficult strange questions. He did not like to memorize facts and rules, but was interested in what lay below the surface of things. When he was four or five years old, for instance, his father gave him a compass. Little Einstein was curious about the mysterious force that could keep a compass needle always pointing north, which prompted him to read widely in science. His real studies were mostly done at home by reading books on mathematics, physics, and philosophy.
Unit 6
Most Americans have great vigor and enthusiasm. They prefer to discipline themselves rather than be disciplined by others. They pride themselves on their independence, their right to make their own minds. They tend to take the initiatives, even when there is a risk in doing so. They have courage and do not give in easily. They are considered sentimental. When they see a flag on ceremonial occasions, or attend parades celebrating Ame rica’s glorious past, tears may come to their eyes. They tend to be emotional at the reunions with family and friends, too. Sometimes, they can laugh at themselves and their country, while they will always remain intensely patriotic.。
