[单项选择]Passage Three
The concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choices based upon current medical knowledge.
We all enjoy our freedom of choice and do not like to see it restricted when it is within the legal and moral boundaries of society. The structure of American society allows us to make almost all our own personal decisions that may concern our health. If we so desire, we can smoke, drink excessively, refuse to wear seat belts, eat whatever foods we want, and live a completely sedentary life style without any exercise. The freedom to make such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but
A. personal health choices help cure most illnesses
B. it helps raise the level of our medical knowledge
C. it is essential to personal freedom in American society
D. wrong decisions could lead to poor health

[单项选择]Passage Two
In the 1960s medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Negative events like "serious illness of a family member" were high on the list but so were some positive life-changing events like marriage. When you take the Holmes-Rahe test you must remember that the score does not reflect how you deal with stress-it only shows how much you have to deal with. And we now know that the way you handle these events dramatically affects your chances of staying healthy.
By the early 1970s hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow the research got boiled down to a memorable message. Women’s magazines ran headlines like "Stress causes illness".

A. the way you handle major events may cause stress
B. what should be done to avoid stress
C. what kind of event would cause stress
D. how to cope with sudden changes in life

[单项选择]Passage Four
The Docklands Light Railway(DLR) took just three years to build at a cost of £77 million. It is London’s first Light Rail System, but its route follows that of a number of older lines, which carried the nineteenth century railways through the crowded districts of the East End.
①The section of the line from the Tower Gateway Station to Poplar follows the line of one of London’s earliest railways, the London & Blackwell(1840), a cable-drawn railway(later converted to steam) which carried passengers to steam ships at Blackwell Pier, and provided transport for the messengers and clerks who went backwards and forwards between the docks and the city every day.
From Poplar to Island Gardens, a new line crosses high above the dock waters, and then joins the old track of the Millwall Extension Railway, built to service the Millwall Docks(1868) and to provide transport for workers in the local factories. This line was horse-drawn for part of it
A. was constructed in the nineteenth century
B. will be finished in three years’ time
C. follows some of the original lines

[单项选择]Passage One
There is a difference between science and technology. Science is a method of answering theoretical questions; technology is a method of solving practical problems. Science has to do with discovering the facts and relationships between observable phenomena in nature and with establishing theories that serve to organize these facts and relationships; technology has to do with tools, techniques, and procedures for implementing the finding of science.
Another distinction between science and technology has to do with the progress in each.
Progress in science excludes the human factor. Scientists, who seek to comprehend the universe and know the truth within the highest degree of accuracy and certainty, cannot pay attention to their own or other people’s likes or dislikes or to popular ideas about the fitness of things. What scientists discover may shock or anger people-as did Darwin’s theory of evolution. But even an unpleasant truth is more
