Most schools forbid chewing gum, but in a few years they might consider changing that rule. Why? Scientists are finding evidence that gum chewing may be good for your health. It may even help improve your test scores.
This exciting research is just beginning. And in the meantime, companies are also experimenting with adding vitamins, minerals, medicines, and other substances that could give gum the power to cure headaches and fight everything from serious diseases to bad breath.
Other researchers are finding that gum might work better than a pill to deliver medicines and other substances into the bloodstream. That’s because the lining (膜) of our cheeks can absorb certain substances more quickly than our stomachs and intestines (肠) can.
That discovery could help other researchers develop medicine-containing gums that fight colds, ease headaches, battle nervousness, and more. Scientists might even create antimicrobial (抗菌的) gums that cure bad breath.
Those projects may take years, but gum scientists have already had at least one recent success: They’ve created a gum that could help us stay awake.
Researchers have produced a gum called Stay Alert. Each stick has as much caffeine as a cup of coffee. It can take an hour for the caffeine in coffee to have its full effect, but the caffeine in Stay Alert hits in just a few minutes.
The gum is easy to transport and it’s stable in cold and hot climates. Unlike a pill, it doesn’t require water to swallow. Those qualities make it easy for soldiers to use.
For now, Stay Alert is available only to the military (军队). The manufacturer may one day offer it for sale to the public. People who work at night, such as truck drivers and medical personnel who ride in ambulances, might benefit from a product like Stay Alert.
1.The passage mainly talks about _____.
A. the rule of forbidding chewing gum in school

As late as 1800, women’s only place was in the home. The idea of woman in the business world was unthinkable. Men were certain that no woman could do a good job outside her home. This was such a widely accepted idea that when the well-known Bronte sisters began writing books in 1864, they had to sign their books with men’s names instead.
Teaching was the first profession open to women soon after 1800. But even that was not an easy profession for women to enter because most schools and colleges were open only to men. Oberlin College i
n Ohio was the first college in America to accept women.
Hospital nursing became respectable work for women only after Nightingale became famous. Seeing that she was not only a nurse but also a rich and well-educated woman, people began to believe it was possible for women to nurse the sick and still be “ladies”. Miss Nightingale opened England’s first training school for nurse in 1860.
The invention of the typewriter in 1867 helped to bring women out of the home and into the business world. By 1900, thousands of women were working at real jobs in schools, hospitals and offices in both England and America. Some women even managed to become doctors or lawyers. The idea that women could work in the business world had been accepted.
Why couldn’t women become teachers easily? Because___________
the first profession open to them was writing.
most schools and colleges were open only to men.
they wanted to be nurses instead.
they had to work in the business world.
The article is mainly about __________.
women are in the business world
the famous Bronte sisters
schools and colleges in America
rights for American women
Which fact does the article lead you to believe?
The Bronte sisters thought that they were men.
England’s first training school for nurses was in Ohio.

科目：高中英语 来源：2013-2014学年广东省山一高三上学期第二次统测英语试卷（解析版） 题型：阅读理解
With large and small keyboards everywhere, neither children nor adults need to write much of anything by hand. That’s a big problem. Study after study suggests that handwriting is important for brain development — helping kids get fine motor skills and learn to express and create ideas. Yet the time devoted to teaching penmanship in most schools has shrunk to just one hour a week. Is it time to give up handwriting? Have a look at the link between the brain and penmanship, and you may get the answer.
A test among students in grades 2, 4 and 6 found that they not only wrote faster by hand than by keyboard, but also created more ideas when composing essays with handwriting. And other research shows that the finger movements required to write by hand activate brain areas involved with thought, language, and short-term memory.
A recent Indiana University study had one group of children practice writing letters by hand while a second group just looked at those letters. Then, both groups of kids entered a functional MRI (核磁共振) that scanned their brains as the researchers showed them the same letters. Researchers found that the brain activity in the first group was far more advanced and “adult-like”.
Handwriting also affects other people’s way they think of adults and children. Several studies have shown that the same average essay will score much higher if written with good penmanship and much lower if written out in poor handwriting. These studies have also found that people judge the quality of a person’s ideas based on his or her handwriting. And the consequences are real: On standardized tests with handwritten sections, like the SAT, all essay that is considered hard to recognize gets a big zero.
Studies show that this isn’t only an English-language phenomenon. Chinese and Japanese youths are suffering from “character amnesia”. They can’t remember how to write characters, thanks to computers and text messaging. Some experts fear that Chinese writing and reading are so closely linked in the brain that China’s reading ability as a nation could suffer.

D
Hawking has left much for Chinese to think about.
British physicist Stephen hawking, possible the world’s most famous scientist after Albert Einstein, gave lectures in Zhejiang and Beijing in August.
An illness left him unable to move any part of his body except for three fingers. But his continuing efforts in the field of science have made many young people take him as their idol（偶像）.
His books, such as A Brief History of Time, become bestsellers in Chinese bookstores. “Hawking helps people enlarge their horizons and become interested in science,” said Pan Yunhe, president of Zhejiang University.
Indeed, experts don’t think it likely that Hawking’ s lectures and profound（深奥的） ideas will be easily understood by the average person. But he has certainly sowed the seeds of science among many young people.
And the “Hawking fever” caused by his visit has made people ask: How can China produce more top scientists like Hawking?
“Nurturing（培养）top scientists will take as much work to change society as to educate the scientists themselves,” said Zhang Fan. Zhang has studied in the UK since 1999 and will be a second – year student at Trinity College in October.
In Britain, Zhang said, teachers inspire students to have a general understanding of the subjects they are interested in. And they encourage students to develop new ideas, which helps them to nurture their creativity.
In China, the Department of Education has encouraged schools to provide quality education to develop students’ potential（潜力）.
“I hope teachers will pay more attention to helping us use our imaginations and solve problems on our own,” said Lu Jie, a Junior Three student in Sanfan Middle School in Beijing.
63. _________ have made young people take Hawking as their idol.
A. Hawking’ s ongoing devotion to science
B. the fact that Hawking is a famous physicist
C. Hawking’ s lectures in Zhejiang and Beijing
D. the fact that Hawking can just move three fingers
64. In paragraph 4, the underlined word “horizons” means “_________”.
A. one’s knowledge of science B. one’s sight of the subjects
C. the area of one’s knowledge D. the line where earth and sky meet
65. From the passage we learn that _______.
A. Hawking’ s books were not popular in China before his visit
B. most schools in China provide quality education to develop students’ potential
C. to nurture top scientists, teachers should solve all the problems for the students
D. ordinary people in China may find Hawking’ s ideas beyond their comprehension
66. The last three paragraphs mainly tell us_______.
A. students in Sanfan middle school are more imaginative
B. teachers should encourage students to be more creative
C. British students do not work as hard as Chinese students
D. top scientists won’t appear even if schools provide quality education

Football is, I believe, the most popular game in England: one has only to go to the important matches to see this. Rich and poor, young and old, one can see them all there, shouting for one side or the other.
To a stranger, one of the most surprising things about football in England is the great knowledge of the game which even the smallest boy seems to have. He can tell you the names of the players in most of the important teams. He will tell you who he expects will win such a match, and his opinion is usually as good as that of men three or four times his age.
Most schools in England take football seriously-much more seriously than nearly all European schools, where lessons are all very important and games are left for the children themselves. In England it is believed that education is not only a matter filling a boy’s mind with facts in the classroom: education also means the training of character; and one of the best ways of training character is by means of games, especially team games; where a boy or girl has to learn to work with others for his or her team, instead of working for oneself alone. The school therefore plans games and matches for its students. Football is a good team game. It is good both for the body and the mind. That’s why it is every school’s game in England.
1.In passage 1, by “this” the author means ________.
|
A．people often go to football games. |
|
B．people, rich and poor, young and old, play football |
|
C．football is the most popular game in England |
|
D．people usually shout at each other in a football match |
2. In England, a boy’s opinion of a match is often ________.
|
A．three or four times better than that of adults |
B．more than that of adults |
|
C．as good as that of adults |
D．worth considering three or four times than adults |
3.In England, education means_______.
|
A．filling a boy’s mind with stories |
B．more than the teaching of knowledge |
|
C．the teaching of knowledge only |
D．training character by means of football games |
