Chocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for” or say “death by chocolate”．Now they should bite their tongues! Evidence(证据) is showing that some kinds of chocolate are actually good for you in the following ways:
A happier heart
Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart．Studies have shown heart benefits from increased blood flow．These benefits are the result of cocoa’s chemicals, which seem to prevent both cell damage and inflammation(炎症)．
Better blood pressure
If yours is high, chocolate may help．Jeffrey Blumberg from Tufts University recently found that people with high blood pressure who ate 3.5 ounces of dark chocolate per day for two weeks saw their blood pressure drop quickly．
Muscle magic
Chocolate milk may help you recover after a hard workout(锻炼)．In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks．
Better for your skin．German researchers gave 24 women a half-cup of special cocoa every day．After three months, the women’s skin was moister(滑润的)and smoother．The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance．
Brain gains
It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain．
【小题1】Which of the following is wrong?                                            

A．Coca’s chemicals can prevent both cell damage and inflammation.

B．Chocolate may help you lower your blood pressure.

C．People early know chocolate is good for their health.

D．chocolate may improve your memory, attention span, reaction time, and problem-solving.

There is a debate going on in America public schools over the best way to teach English to foreign students. Many schools use bilingual education. This means that students study their core subjects such as science, mathematics and social studies in their native tongues. They also take a few h ours of English.
Recently, many educators have begun to criticize bilingual education. Opponents claim that bilingual education slows not only students’ development of language skills but also their adjustment to American life. They often remain separated from the mainstream student body.
These critics have proposed the immersion method (沉浸式语言教学法). This means that students take only English classes until they can function effectively in regular subject classes. Proponents of the immersion theory argue that in order to prepare these foreign students for college or the job market, they must be able to communicate in English.
Despite this disagreement, nearly all educators agree that English is a necessary tool for improving the quality of one’s life in America.
72. In bilingual education programs, students ______.
A. study in their native countries

A. Nearly all educators agree that English is important for foreign students.
B. Students in bilingual education programs are often separated from American students
C. Nearly all educators agree that bilingual education is best for teaching English to foreign students.
D. Students with good English language skills have better chances for college or the job market.
75. What is the author’s opinion about the bilingual education in America?

C. He doesn’t show his own opinion  D. He is against all the educators

Of the 7,000 languages spoken in the world today, linguists (语言学家) say, nearly half are likely to disappear this century. In fact, one falls out of use about every two weeks.

    Some languages die out in an instant, at the death of the only surviving speaker. Others are lost gradually in bilingual (双语的) cultures, as local tongues are edged out by the dominant (占主导地位的) language at school, in the marketplace and on television.

    New research, supported by the National Geographic Society and the Living Tongues Institute for Endangered Languages, has found the five regions where languages are disappearing most rapidly. They are northern Australia, central South America, North America's upper Pacific coastal zone, eastern Siberia, and Oklahoma and the southwestern United States.

K. David Harrison, an associate professor of linguistics at Swarthmore College, US, said that more than half the languages had no written form and were vulnerable to loss and being forgotten." Their loss leaves no dictionary, no text, or no record of the accumulated knowledge and history of a disappeared culture.

    Harrison and other researchers started their rescue project last year. They have been trying to identify and record endangered languages. They interviewed and made recordings of the few remaining speakers of a language and collected basic word lists. The individual projects, some lasting three to four years, involve hundreds of hours of recording speech, developing grammar and preparing children's readers in the obscure (逐渐没落的) language. The research has concentrated on preserving entire language families.

    "These are probably languages that cannot be brought back, but at least we made records of them," said Gregory Anderson, director of the Living Tongues Institute, in Oregon, US.
