Inventor，physicist，surveyor，astronomer，biologist，artist…Robert Hooke was all these and more．Some say he Was the greatest experimental scientist of the 17th century．In the course of his work，he cooperated with famous men of science like Isaac Newton，and the great architect, Chrish@ler Wren．
Hoocke's early education began at home，under the guidance of his father．He entered Westnfinster School at the age of 13，and from there went to Oxford，where he came in contact with some of the best scientists in England．Hooke impressed them with his skills at designing experiments and inventing instruments．In 1662，at the age of 28, he was named Curator of
Experiments at the newly formed Royal Society of London—meaning that he was responsible for demonstrating new experiments at the society’s weekly meetings．Hooke accepted the job，even though he knew that the society had no money to pay him!
Watching living things through a microscope was one of his favorite pastimes．He invented a compound microscope for this purpose．One day while observing a cork(软木塞)under a microscope，he saw honeycomb-like structures．They were cells—the smallest units of life．In fact，it was Hooke who invented the term“cell” as the boxlike ceils of the cork reminded him of the cells of a monastery(修道院)．
Another achievement Of Hook’s was his book Micrographi which introduced the．Enormous potential of the microscope．It contains fascinating drawings of the things he saw under the  microscope．The book also includes，among other things，ideas on gravity，light and combustion(燃烧)that may have helped scientists like Newton when they were developing their own theories on these phenomena．
Hooke made valuable contributions to astronomy too．A crater(坑)on the moon is named  after him in appreciation of his services to this branch of science．
68．Why possibly did Hooke accept the job as Curator of Experiments?
A. Because his parents couldn’t afford his education．
B．Because his family needed his support．
C．Because he wanted to please the famous scientists in England．
D．Because he liked designing experiments．
69．The cell got its name because of      ．
A．its use    B．its shape    C．Hooke’s favorites D．Hooke’s experiences
70．The last paragraph is to prove that          ．
A．Hooke was the greatest experimental scientist of the 17th century
B．Hooke was good at making discoveries
C．Hooke’s contributions were not limited to one field
D．Hooke was one of the greatest astronomers
71．The best title for the text may be          ．
A．The Greatest Scientist                B．A Helper of Newtom
C．A Brief Introduction to Hooke          D．Achievements of Hook

Eating a diet high in processed food(加工食品)increases the risk of depression，research suggests．What's more，peopie who ate plenty of vegetables，fruit and fish actually had a lower risk of depression，the University College London team found．
Data on diet among 3，500 middle-aged civil servants(公务员)were compared with their emotional state five years later，a British journal reported．They split the participants into two types of diet--those who ate a diet largely based on whole food，which inc!udes lots of fruit， vegetables and fish，and those who ate a mainly processed food diet，such as sweetened desserts，fried food，processed meat，refined grains and high fat dairy products After accounting for factors such as gender，age，education，physical activity，smoking habits and chronic(慢性的) diseases，they found a significant difference in the future depression risk with the different diets．
Those who ate the most wholefood had a 26％ lower risk of future depression than those who ate the least wholefood．By contrast，people with a diet high in processed food had a 58％ higher risk of depression than those who ate a diet low in processed foods．
Study author Dr. Archana SinghManoux pointed out there was a chance the finding could be explained by fl lifestyle factor they had not accounted for．
There was a paper showing a Mediterranean diet was associated with a lower risk of depression，but the problem with that is if you live in Britain，the likelihood(可能性)of you eating a Mediterranean diet is not very high．
Dr．Andrew McCulloeh，chief executive of the Mental Health Foundation，said，this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health．
He added people's diets were becoming increasingly unhealthy．The UK population is consuming less nutritious，fresh produce and more saturated(含饱和脂肪酸的)fats and sugars．

There is probably no field of human activity in which our values and lifestyles are shown more clearly and strongly than they are in the clothes that we choose to wear. The dress of an individual is a kind of "sign language" that communicates a set of information and is usually the basis on which immediate impressions are formed. Traditionally, a concern for clothes was considered to be an affair of females, while men took pride in the fact they were completely lacking in clothes consciousness(意识).
This type of American culture is by degrees changing as man dress takes on greater variety and color. Even as early as 1995, a researcher in Michigan said that men attached rather high importance to the value of clothing in daily life. White－collar workers in particular viewed dress as a symbol of ability, which could be used to impress or influence others, especially in the work situation. The white－collar worker was described as extremely concerned about the impression his clothes made on his superiors(上司). Although blue－collar workers were less aware that they might be judged on the basis of their clothing, they recognized that any difference from the accepted pattern of dress would be made fun of by fellow workers.
Since that time, of course, the patterns have changed; the typical office worker may now be wearing the blue shirt, and the laborer a white shirt, but the importance of dress has not become less.      Other researchers in recent years have helped to prove its importance in the lives of individuals at various levels and in different social and economic status groups(阶层).

Adrian’s “Amazing Race” started early when his parents realized that he, as a baby, couldn’t hear a thing, not even loud noises. In a special school for the hearing-impaired (听觉受损的)，he learned sign language and got to mix with other disabled children. However, the sight of all the disabled children communicating with one another upset his mother. She wanted him to lead a normal life. So after speaking to an advisor, she sent him to private classes where he learned to read lips and pronounce words.
Later on, Adrian’s parents decided to send him to a regular school. But the headmaster tried to prevent them from doing so, saying regular school couldn’t take care of a special needs students. His parents were determined to take the risk and push him hard to go through his work everyday because they wanted to prove that, given the opportunity, he could do anything. Adrian made the grade and got accepted. It was a big challenge. The pace （节奏）was faster so he had to sit at the front of the class and really pay attention to the teacher, which wasn’t always easy. But he stuck to it and did a lot of extra work after school.
The efforts made by Adrian and his parents paid off. Adrian graduated with good grades and got into a top high school. He also achieved a lot in life outside school. He developed a love for the outdoors and went to Nepal to climb mountains. He even entered the World Yacht Race 05/06--- being the first hearing-impaired Asian to do so.
But none of these achievements would have been possible without one of the most important lessons from his mother.” “If you believe in yourself and work hard, you can achieve great results.” She often said.
【小题1】How did Adrian communicate with other children in the special school?

More than 1.5 billion people around the world live without electricity. Finding better ways to bring light to the poor is the goal of researchers like Professor Irvine. In the late 1990s, he was working in Nepal when his return flight was canceled. A delay gave him time to take a fourteen-day hiking trip in the Himalayas.
One day he looked in the window of a school and noticed how dark it was. This is a common problem for millions of children around the world. Many families use kerosene oil (煤油) lamps. There are many problems with these lamps. They produce only a small amount of light. They are dangerous to breathe. And they are a big fire danger, causing many injuries and deaths each year. Kerosene costs less than other forms of lighting, but it is still costly in poor countries. Professor Irvine says many people spend over 100 dollars a year on the fuel.
When he returned to Canada, he began researching ways to provide safe and clean lighting. He began experimenting with light-emitting diodes (发光二极管), LEDs, at his lab. As a professor of renewable energy, he already knew about the technology. Light-emitting diodes are small glass lamps that use much less electricity than traditional bulbs (灯泡) and last much longer. He used a one-watt bright white LED made in Japan. He found it on the Internet and connected it to a bicycle-powered generator (发电机). He remembers thinking it was so bright that a child could read by the light of a single diode.
In 2000, after much research and many experiments, he returned to Nepal to put the systems into homes. Now the homes of 25,000 people in 51 countries have been equipped with it. “The one-time cost of our system which basically lives forever, as well as the solar panel — is less than one hundred dollars. So, one year of kerosene would pay for a solid-state lighting system,” he said. Now his aim is to develop a lower-cost lighting system. In January, Irvine is leaving the University of Calgary. He has also decided to start his own company in India.
