Two American scientists told the people in industrial nations that they would be much healthier if they ate more of the same kind of foods eaten by humans living more than 10,000 years ago.
The scientists say that the human body has changed very little since human first appeared on earth, but the way we live has changed greatly. Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times. So they are called “diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes(中风) are examples of such diseases.
Scientists noted that early stone-age people used very little alcohol or tobacco, probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and life today.
Stone-age people hunted wild animals for their meat, which had much less fat than farm animals. They also ate a lot of fresh wild vegetables, and fruits. They did not use milk and other dairy products, and they made very little use of grains. But today, we eat a large amount of dairy products and grain foods. We eat six times more salt than stone-age people. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C.
People today probably do not want to live as people thousands of years ago did, but scientists say that we would be much healthier if we ate as those ancient people did, cutting the amount of fatty, salty and sweet foods.
1.The people in industrial nations would be much healthier if they ate ______.
A.more foods as humans living 10,000 years ago did
B.as humans living 10,000 years ago ate
C.more kinds of food eaten by people living over 10,000 years ago
D.more of the same kinds of foods eaten by people over 10,000 years ago
2.New kinds of sicknesses have been found because ______
A.the human body has changed compared with human first appearing on earth
B.the way we live has changed a little
C.our body can’t deal with the changes in life style
D.the way we live today are improper for the human body
3.What is the main cause mentioned in the article why people suffer from a lot of new sicknesses?
A.Ancient people did a great deal of physical exercise.
B.People today have a lot of alcohol.
C.People today have more tobacco.
D.Food is quite different between life today and life in ancient times.

高二英语单项填空中等难度题查看答案及解析
Many Chinese people are confused with the two nations: one is known for its cheese and watches; the other for IKEA and Volvo.
The problem largely stems from the fact that both nation’s names are written similarly in Mandarin---Ruidian(Sweden) and Ruishi (Switzerland)------which begin with the same symbol, according to the Swedish Consul General Victoria Liu in China.
In an effort to put an end to the mix-up, the Swedish and Swiss governments have launched a competition on a website, asking Chinese people to come up with funny ways to help differentiate the two countries. Submissions can be accepted as a blog post, cartoon, photo, short film or in any other format.
The winner with the best submission will receive a 12-day trip to Sweden and Switzerland and will be expected to report back on his/her impressions of both countries following the trip, the website states. Entries will be accepted until November 20.
The organizers have also devised a humorous campaign logo with objects and people associated with Sweden and Switzerland on separate maps of each country. Sweden’s map features meatballs, a Viking, as well as two male cartoon figures with a heart between them symbolizing gay marriage, which remains illegal in Switzerland. Switzerland’s map features cheese, the Alps and a picture of Roger Federer.
China may not be the only country struggling to tell Sweden and Switzerland apart. Residents of Spanish-speaking countries also fall victim to the confusion as Sweden is spelt “Suecia” in Spanish while Switzerland is called “Suiza”.
Sweden and Switzerland aren’t the only places that have caused confusion among people. Last month, , a British holidaymaker hoped to explore the architecture of the Alhambra Palace in Granada, Spain, but instead mistakenly caught a flight across the Atlantic to the tropical Caribbean island of Grenada following a confusing booking blunder. Earlier this summer, two US holidaymakers were flown to the wrong continent after an airline confused two airport codes.
1.What can we learn about the competition launched by the two governments?
A. The winner of the competition will receive a 24-day trip altogether to both of the countries.
B. The winner will report his/her impressions on the two countries in his/her submission.
C. The competition is held among all people around the world.
D. The competition is held in order to stop people’s confusion about the two countries.
2.Why does the author mention the British holidaymaker?
A. To show us many people are confused by Sweden and Switzerland.
B. To prove airports make mistakes about people’s places too.
C. To explain Spanish-speaking people make mistakes too.
D. To prove many people are confused about some places.
3.In which part of a newspaper could you probably find the passage?
A. Tourism B. News review C. Business D. Culture
4.What does the underlined word “devised” mean?
A. Compared. B. Collected. C. Invented. D.Installed

Scientists have always been interested in the high level of organization in ant societies. American researchers have watched ants build life-saving rafts to keep afloat during floods. They also have recorded how ants choose their next queen — the female whose job is to produce eggs.
New technology is helping to improve researchers’ understanding of the insects. But there is still a lot to be learned.
Fire ants living in Brazilian forests are perfectly at home in an environment where flooding is common. To save themselves, the insects connect their legs together and create floating rafts. Some ant rafts can be up to 20 centimeters wide.
David Hu is an engineer with the Georgia Institute of Technology, also known as Georgia Tech, saying, "If you have 100 ants, which means 600 legs, 99 percent of those legs will be connected to a neighbor. So they’re very, very good at keeping this network."
David Hu and other Georgia Tech researchers wanted to study ants and the secret of their engineering. They froze ant rafts and then looked at them with the help of computed technology, or CT images. The pictures showed that larger ants serve in central positions to which smaller ants hold. The larger ants create pockets of air that keep the insects afloat.
Scientists say small robots or materials that can change shape could be programmed in a similar way, working towards a shared goal.
Researchers at North Carolina State University are also studying ants. They examined how Indian jumping ants choose the leader of the colony when they lose their top female or queen.
1.The author takes fire ants as an example to tell us ________.
A. how ants survive B. how ants seek food
C. how ants communicate D. how ants live together
2.What can we know from what David Hu said in paragraph 4?
A. Ants know the way to keep in touch in the river.
B. Ants know the way to join together closely.
C. Ants know the way to look for each other.
D. Ants know the way to build a large raft.
3.Why did the larger ants serve in central positions in their ant rafts?
A. To stress their importance. B. To help all the ants float.
C. To fight against the enemies. D. To defend their top female.
4.What ideas do the ants give us according to the passage?
A. We can use similar-shaped machines in flooding areas.
B. We can combine small robots or materials into larger ones.
C. Small and shape-changeable things might work just like ants do.
D. Small robots or materials in the shape of ants can be made.
