In one of the strongest indications of the power of the mind to influence the body a growing collection of evidence finds that people who are depressed (抑郁的) have a greatly higher risk of developing heart disease.

In a study of almost 3,000 men and 5,000 women, depressed men were 70 per cent more likely to develop heart disease than those who weren't depressed. While depressed women were just 12 per cent more likely to develop heart disease, those who were severely depressed were 78 per cent more likely.

In fact, a 1998 study found that women who are depressed have a risk of dying from heart disease equal to that of women who smoke or who have high blood pressure.

The link works the other way around, too: While about 1 in 20 American adults experience major depression in a given year, that number jumps to about one in three among those who have survived a heart attack.

The more severe the depression, the more dangerous it is to your health. But some studies suggest that even mild depression, including feelings of hopelessness experienced over many years, may damage the heart. Other studies suggest depression may affect how well heart disease medications work.

Researchers aren't sure what the connection between depression and heart disease is, but theories exist. One is that people who are depressed tend not to take very good care of themselves. They're more likely to eat high-fat, high-calorie "comfort" foods, less likely to exercise, and more likely to smoke. But beyond lifestyle, there is probably also a physiological link between depression and heart disease. Recent studies found that people with severe, depression tended to have a lack of heart-healthy 0-3

fatty acids. People who are depressed also often have high levels of stress hormones (荷爾蒙). These keep the body primed for fight or flight, raising blood pressure and causing the heart to beat faster, all of which put additional stress on coronary arteries (動(dòng)脈) and prevent the body's natural healing

mechanisms from working properly.

A whole branch of medicine is devoted to the complex links between mental health, the nervous system, the hormone system and so on. This science is gradually sorting out how the mind-body connection affects us, or defenses against heart disease.

Generally, an estimated 10 per cent of American adults experience some form of depression every year. Although available treatments can ease symptoms（癥狀）in more than 80 per cent of people treated, less than half of those with depression get the help they need.

72. Which of the following can be the best title of the passage?

A. Depression -- Heart Disease Risk Factor

A. depressed ones tend to eat high-fat and high-calories foods, which leads to physical damage to heart

B. severe heart disease may cause people to feel hopeless and depressed

C. depression may result in the lack of some kind of acids, which probably affects the working of people's heart

D. people with depression often have a high level of stress hormones, maybe, which will put extra pressure on one s heart

For a 400-year-old art form, operas had a bad fame: overweight actresses singing the words which are hard to understand in one of those romance languages you were supposed to learn in high school. And with tickets costing as much as $ 145 a performance, opera goers also have a certain appearance in people’s mind: rich, well-dressed and old.

But now opera companies around the country are loosening their ties and kicking off their shoes in an attempt to bring the opera to the audience. It needs to keep it alive, the young and not-so-rich.

Opera producers have found that to attract this crowd, they need to make the opera closer to common people. That means no formal suits, old-styled theatre or band-breaking ticket prices. And because young people don’t or won’t come to the opera, companies are bringing the opera to them, giving performances in such unusual places as parks, libraries and public schools.

The Houston Grand Opera’s choice is the public library, where it performs “mobile operas”, shortened versions (劇本) of child-friendly operas. This summer’s production is Hansel & Gretel. By performing smaller versions of large productions, producers are able to make people interested while keeping costs at a reasonable level. The San Francisco Opera, which will be celebrating its 75th anniversary this year, is staging Cinderella free of charge, keeping costs down by employing students from its Young Artists’ Training Program.   

Which of the following is the main idea of this passage?

       A．Opera is famous for is history.                                   

       B．Opera is only for rich people.

       C．Opera companies are trying to keep opera alive.                            

       D．Young people are not interested in opera. 

The underlined part in Paragraph 2 most probably means          .

       A．breaking up the old rules       B．changing the dresses

       C．making the audience at ease    D．a(chǎn)dvertising themselves

Opera companies prefer to perform smaller versions because         .

       A．they can be performed  in public libraries

       B．short versions are easy to perform

       C．it is hard to find long versions

       D．they can make people interested

The San Francisco Opera employs young students in order to        .

       A．a(chǎn)ttract young people               B．reduce the cost

       C．celebrate its 75th anniversary   D．make Cinderella popular

What can you infer from the passage?

       A．The tickets for opera are very expensive at present.

       B．Opera is performed in a language difficult to understand.

       C．Opera is not so popular an art form today.

       D．Students enjoy performing operas very much.

 Every object tells a story. Even the most ordinary objects can present to us powerful images. Sometimes it is the ordinary nature of these objects that actually makes them so extraordinary. Such is the case with an old leather shoe in a museum in Alaska. At first glance it does not look like much. It is a woman’s shoe of a style popular in the 1890s. But what is unique(獨(dú)特的) about this shoe is where it was found. It was discovered on the Checkout Pass, the famous trail used by the people seeking gold in Alaska. Who it belonged to or why it was left there is not known. Was it perhaps dropped by accident as the woman climbed up the 1500 stairs carved outface? Or did she throw away goods that she didn’t need in order to travel lighter?

Over 100, 000 people with “gold fever” made this trip hoping to become millionaires. Few of them understood that on their way they would have to cross a harsh wildness. Unprepared for such a dangerous journey, many died of starvation and exposure to the cold weather.

The Canadian government finally started requiring the gold seekers to bring one ton of supplies with them. This was thought to be enough for a person to survive for one year. They would carry their supplies in backpacks(背包) each weighing up to fifty pounds; it usually took at least 40 trips to get everything to the top and over the pass. Whoever dropped the shoe must have been a brave and determined woman. Perhaps she was successful and made it to Alaska. Perhaps she had to turn back in defeat. No one will ever know for sure, but what we do know is that she took part in one of the greatest adventures in the 19th century.

1.The ordinary woman’s leather shoe is considered unusual because ______. 

A. it was an important clue to life in the past

B. it was found on a famous trail

C. it at one time belonged to a VIP    

D. it was a fashionable shoe at that time

2.According to this passage, many people who went to Alaska ______. 

A. eventually became millionaires           B. brought with them many shoes

C. had conflicts with the Eskimos           D. were not properly equipped

3. The Canadian government made gold seekers bring one year’s supplies with them so that ______.

A. they would not die of hunger and cold

B. the army would have enough food for fighting a war

C. they would change these goods with the Eskimos

D. the supplies would make Alaska rich

 

4.No matter what happened to the woman who owned the shoe, ______. 

A. she must have lived a happy life

B. she certainly dropped the shoe on purpose

C. her adventurous spirit is definitely admired

D. her other shoes were equally fashionable
