举一反三
The easiest way for the English to deal with their social discomfort is to avoid social interaction altogether, by choosing either leisure (闲暇) activities that can be performed in the privacy of one’s own house, or outdoor activities that follow their interest without direct contact with anyone other than one’s own family members, such as going for a walk, or to the cinema, or shopping．
In recent survey, over half of all the leisure activities were of this private domestic type, and of the top ten pastimes, only two—having friends round for a meal or drink, and going to the pub—could be described as ‘sociable’．The most domestic activities are the most popular: watching TV, listening to the radio, reading, DIY （Do It Yourself） and gardening．Even when the English are being sociable, the survey findings show that most of them would much rather entertain a few close friends or relatives in the safety of their own homes than venture out among strangers．
In the latest national census survey （人口普查）, over half of the entire adult male population had been DIYing in the four weeks before the census date．Nearly a third of the female population had also been busily improving their homes, and their work with their gardens was equally obvious: 52 percent of all English males and 45 percent of females had been out there, cutting branches and weeding grass．
Even among people claiming to belong to a particular religion, only two percent attend services every week．The rest of the population can be found every Sunday at their local garden center or DIY superstore．And when they want a break from caring about their own homes and gardens, they go on trips to visit bigger and better houses and gardens, such as the stately homes and gardens opened to the public by the National Trust and the Royal Horticulture Society．Visiting grand country houses always ranks as one of the most popular national pastimes．
45．The result of the survey shows that ________.
A．about half English people enjoy working in their gardens
B．8 out of 10 pastimes can be described as social activities
C．2 percent of the religious people enjoy visits to public houses
D．visiting stately homes is the most popular national pastime
46．According to the passage, the English enjoy all of the following EXCEPT________.
A．the social activities, such as gathering with friends
B．working at home and in their gardens
C．dining out in a public place among strangers
D．visits to stately homes and gardens
47．The underlined word “domestic” probably means________.
A．public B．household C．outdoor D．collective
48．The passage mainly tells us about________.
A．why the English don’t like social activities
B．how the English spend their leisure time
C．what the result of a recent census survey is
D．where the English hold their private activities

It’s likely that everything you learned about America’s ancient history is wrong.
The new book, 1491, completely changes our understanding of the Americas before the arrival of Columbus in 1492.
DID YOU KNOW?
When Columbus landed there were probably more people in the Americas than there were in Europe.
The peoples of North America had such healthy life-styles that as late as the 19th century they continued to be the tallest people on earth.
Facts have shown that the Americas were populated as long as 33,000 years ago.
4,000 years ago Mesoamerican farmers developed corn in a feat (技艺) of genetic engineering that still isn’t completely understood.
COMMENTS ON 1491
“In the tradition of Jared Diamond & John McPhee, a totally new view of pie-Columbian America” --Richard Rhodes
“Attractively written and really absorbing ... Charles C. Mann has produced a book that’s part detective story, part epic (史诗) and part tragedy. He has taken on a vast topic: thousands of years, two huge continents, and cultures.”
-- Charles Matthews, San Jose Mercury News
“Powerful and challenging”
--Alan Taylor, Washington Post
“A pleasure to read as well as a wonderful education” -- Howard Zinn

As a girl, she was inspired by the work of great scientists: she read the story of the cure of malaria in the Panama Canal; she also read a biography of Madame Curie．These accounts inspired her to pursue a career in scientific research．After high school, she worked for the Michigan Department of Health, where she did research in biology and microbiology．There, her colleagues saw her talent and encouraged her to pursue science as a career．She went on to earn a bachelor’s degree from Michigan State University in 1948 in medical technology．When she began working at Michigan State in the early 1960s,
she was balancing the demands of scientific research with the needs
of her family．At that time both of her children were in school．She
would work in the lab in the morning while they were at school,
go home to see them at lunch, return to the lab for the afternoon, go
home for dinner, and return to the lab in the evening, if necessary．
At that time, there were fewer women scientists working than
there are today, but she encountered several in her career．At the
Michigan Department of Health, many of her colleagues were women and, consequently, she did not feel isolated because of her gender–nor did she feel that she was treated differently because she was a woman．
While working at Michigan State, she also felt that she was treated with respect by her peers．Her colleagues, among them doctors and Ph．D．chemists, all treated her as an equal．On the whole, she believes that there is not a great deal of difference between men and women in science．
56．Why does the woman scientist refuse to let out her name?
A．Because she is a shy lady．
B．Because she doesn’t mind her fame．
C．Because she never takes pride in her research．
D．Because she never works for her fame．
57．What is the noble lady scientist really interested in?
A．The life stories of other women scientists．
B．Biology and microbiology．
C．The secret of the success of the other scientists．
D．The difference between men and women scientists．
58．Who helped and encouraged her to carry on her scientific research?
A．Her family and friends． B．Madame Curie．
C．Her colleagues and other scientists． D．Some of the officials．
59．What is the whole passage mainly about?
A．The life story of a famous woman scientist with great success．
B．A brief introduction about an unknown great woman scientist．
C．The new development of a special woman scientist．
D．The secret of an infamous woman scientist．

Plants, like animals, are subject to diseases of various kinds．It has been estimated that some 30,000 different diseases attack our economic plants; forty are known to attack corn, and about as many attack wheat．The results of unchecked plant disease are all too obvious in countries which have marginal food supplies．The problem will soon be more widespread as the population of the world increases at its frightening rate．Even in countries which are now amply fed by their agricultural products there could soon be the major crops; the resulting famines(饥荒) could kill millions of people, and the resulting hardship on other millions could cause political upheavals(动乱) disastrous to the order of the world．
Some plants have relative immunity to a great many diseases, while others have a susceptibility to them．A blight (萎菌病) may be but a local infection easily controlled; on the other hand it can attack particular plants in a whole region or nation．An example is the blight which killed virtually every chestnut tree in North America．Another is the famous potato blight in Ireland in the last century．As a result of that, it was estimated that one million people died of starvation and related ailments．
Plant pathologists have made remarkable strides in identifying the pathogens of the various diseases．Bacteria may invade a plant through an infestation of insect parasites carrying the pathogen．A plant can also be inoculated by man．Other diseases might be caused by fungus which attacks the plant in the form of a model or smut or rust．Frequently such a primary infection will weaken the plant so that a secondary infection may result form its lack of tolerance．The symptoms(症状) shown may cause an error in diagnosis, so that treatment may be directed toward bacteria(细菌) which could be the result of a susceptibility caused by a primary virus infection．
小题1:How many diseases are known to attack wheat?
| A．Around 30000 | B．Forty |
| C．Around 29960 | D．Around 40 |
| A．food shortages in poor country | B．food shortages in rich country |
| C．increase of world population | D．disaster in world politics |
| A．Some plants have relative immunity to a great many diseases． |
| B．Some other plants have a susceptibility to a great many diseases． |
| C．The tolerance of a particular plant changes as the growing conditions change． |
| D．A blight can be a national infection． |
| A．infect people |
| B．be prevented by inoculation（接种疫苗） |
| C．be prevented by killing insects |
| D．be prevented by improving the growing conditions |
| A．Fungus | B．Mold | C．Smut | D．Rust |
