A small piece of fish each day may keep the heart doctor away. That’s the finding of a study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce of salt water fish per day compared to those who never ate fish.
The Dutch research is one of three human studies that give strong scientific support to the long held belief that eating fish can provide health benefits, particularly to the heart.
Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year. But researchers previously have noticed that the incidence (发生率) of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.
For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish.
At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.
During the next two decades, 78 of the men died from heart disease. The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol（胆固醇）levels. The passage is mainly about _________.
| A．the high incidence of heart disease in some countries |
| B．the changes in people’s diet |
| C．the effect of fish eating on people’s health |
| D．the daily fish consumption of people in different cultures |
We can infer from the passage that there are fewer heart disease deaths ________.
| A．in the countries with high consumption of fish |
| B．in highly-developed countries |
| C．in countries of the yellow-skin race |
| D．in the countries with good production of fish |
The phrase “this relationship” in paragraph 6 refers to the connection between ______ and the incidence of heart disease.
| A．the amount of fish eaten | B．regular fish-eating |
| C．the kind of fish eaten | D．people of different areas |
If you don’t prepare yourself now, retirement may be some of the most boring and dull years of your life. To have a happy, fulfilling retirement, you need to start preparing right away.
The most obvious thing for people to do when they retire is to take up a hobby. The most important step to take before retiring, though, is to make sure that you actually have started some hobbies. Once you’re retired, unless you ‘ve already started a hobby, you’ll find it very hard to get into something new. Some hobbies aren’t for everyone. Think about what you enjoy doing and start participating on a casual basis now.
Another thing many people participate in is volunteering. Not only does volunteering give you something to do, it also gives you a sense of accomplishment(成就) and can add meaning to your life .Volunteering is also rewarding in other ways, too. There are hundreds of different types of volunteer services and you’ll always be able to meet new and interesting people. Also, don’t think that volunteering is always only about helping someone for free. Many companies pay their volunteers after they’ve had enough experience and prove themselves to be valuable workers.
There are plenty of other potions, as well. Going back to school is a great way to keep yourself feeling young. Taking a vacation around the world with your loved ones is another great way to spend your retirement.
Ultimately, though, the key to a happy retirement is simply keeping yourself busy and doing whatever you love. If there’s nothing you love doing now, then you’ll find that once you have a vast amount of free time, your life will be pretty empty. Now is the time to find out what you want to do when you retire.Why does the author suggest starting a hobby before retirement?
| A．Because we are likely to have difficulty starting a hobby after retirement. |
| B．Because we are gong to have a vast amount of free time after retirement. |
| C．Because we will only have a limited choice of hobbies after retirement |
| D．Because not every one of us has already started some hobbies already. |
What can we learn about volunteering from the text?
| A．We can make devoted friends through volunteering. |
| B．It can help companies find hard-working workers. |
| C．One can even make some money by volunteering. |
| D．Almost everyone is willing to help in some way. |
Which of the following can best explain “a happy retirement”?
| A．Travelling around the world every year. |
| B．Going back to university for further study. |
| C．Having plenty of free time for one’s hobbies. |
| D．Living a busy life and doing what one enjoys doing |
A super drug that could remove Alzheimer’s (老年痴呆症)，heart disease and diabetes (糖尿病) and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the “ longevity genes” will allow millions to live longer, predicts Dr Nir Barzilai.
Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer’s. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise.
Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. “ The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing,” he said.
Of the three longevity genes, two genes increase the production of so-called good cholesterol(胆固醇), which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai’s team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: “ 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100.”
But Andrew Ketteringham of the Alzheimer’s Society said: “Alzheimer’s disease, a most common disease, is likely to be caused by a combination of genetic disosition(遗传倾向), lifestyles and life events. Many genes are probably involved. Some people are able to live to 100 years because of ______.
| A．a magical medicine | B．three special genes | C．good living habits | D．longevity proteins |
Why does the discovery of the longevity genes mean a lot?
| A．Because it can bring great benefits to scientific labs. |
| B．Because it can help people change their unhealthy genes |
| C．Because it helps produce a drug that can make people live longer. |
| D．Because it will help scientists build up a new branch of biology. |
From Paragraph 4 we can infer that ________.
| A．longevity genes can create good cholesterol. |
| B．the volunteers share some common ancestors |
| C．bad habits are likely to have no effect on the volunteers |
| D．longevity genes protect the volunteers against bad habits |
What is Andrew Ketteringham’s attitude toward the study?
| A．Positive | B．Negative | C．Critical | D．Cautious |
Jeans are trousers made of a kind of clothe called denim. For many people, blue jeans represent American culture.
The history of blue jeans usually begins with a man named Levi Strauss. Although he did not invent the jeans, he is considered the first person to produce and sell this kind of clothing in large amounts.
Levi Strauss was born in Bavaria, Germany. In 1847, he and his family moved to the US. He opened a store, first in New York, and then in San Francisco, California. Among the products he sold were jeans. These trousers were especially useful for miners in California who needed clothing made of a strong material.
Levi Strauss partnered with a clothing maker named Jacob Davis, who had invented a process for making rivets(铆钉) for jeans. These metal things helped strengthen the blue jean cloth to make the trousers stronger. In 1873, Strauss and Davis received a patent to officially own this invention. They began producing “ copper-riveted waist overalls(工装裤)”. In 1928 the Levi Strauss company used the word “Levi’s” as the trademark for their products.
The 19th-century workers would probably be surprised to know that their trousers would one day become a fashion object. Today, jeans are worn by people of all ages, incomes and lifestyles. Jeans come in many colors other than blue and in many styles and at many prices.
A national museum in Washington, D.C. has one of the oldest known pairs of Levi’s jeans in its collection. Jeans have come to express different ideas about American culture based on the people who wear them. These include the heroes of the Wild West and famous Hollywood actors like James Dean and Marlon Brando in the 1950s. Writer James Sullivan published a book called Jean: A Cultural History of an American Icon. In the book, he says jeans serve as a sign for two American values, creativity and rebellion (叛逆).This passage is mainly about _______.
| A．the life story of Levi Strauss | B．jeans and American culture |
| C．why jeans are popular. | D．the history of jeans |
We know from the passage that Levi Strauss _________.
| A．was the first person who wore jeans. | B．moved to the US from Germany alone. |

My mother-in-law, Dorothy, is showing me the red notebook that’s almost as precious to her as my husband’s baby pictures. Inside the notebook is a list of the books she has read since 2007. For some people waking up in the middle of the night is a terrible thing. But for my mother-in-law, that time is a gift. At 87, she is getting the education she never had by working her way through great literature. She has now read close to 100 books, including every single novel by Anthony Trollope, Charles Dickens, Jane Austen, Edith Wharton, Henry James and Thomas Mann.
My mother-in-law discusses her passion with the enthusiasm of a young girl, although she can also be a very tough critic, writing “VG’ for “ very good” in the margins next to her favorites. So far, only a handful of books have received the top prize.
Born in Ridgefield, Conn, Dorothy was the youngest daughter of an Italian gardener. She taught herself English by reading The New York Times. Eager to come to Manhattan, she became a nurse, married a dentist and spent the next several decades keeping the house and raising a family. In her later years, she put her nursing skills to good use by taking care of my father-in-law, who had lung cancer. There were many trips to the emergency room in the middle of the night and then a long hospital stay. She stayed awake to watch over him for 15 hours a day. Always a light sleeper, she developed sleeplessness as a result of the stress.
It worsened after he died. Deeply sad and lonely for the first time in her life, she began waking up around 2am. Julian and Sylvia, the elderly couple next door suggest she read literature. And so Julian, a great lover of literature, became her “professor”, providing books from his large library. Suddenly the terrifying hole turned onto a world of amazing characters.Why is Dorothy considered a tough critic?
| A．Because no books are inspiring enough in her eyes. |
| B．Because only a few books are thought highly of by her. |
| C．Because she only reads books by famous writers. |
| D．Because she finds fault with every book she reads. |
It can be inferred from the passage that _____.
| A．the books Dorothy has read were bought by her husband. |
| B．the couple next door are college professors. |
| C．the author loves literature too. |
| D．Dorothy was a great wife. |
The underlined part “the terrifying hole” in the last paragraph refers to _____.
| A．the frightening death |
| B．Dorothy’s lack of education |
| C．waking up in the middle of the night |
| D．a hole in a book that Dorothy read |
What helped Dorothy get over the sadness and loneliness of losing her husband?
| A．Living with her son. |
| B．Reading literature. |
| C．Seeing her son’s baby pictures. |
| D．Talking with neighbors. |
Everyday we go to school and listen to the teacher, and the teacher will ask us some questions. Sometimes, the classmates will ask your opinions of the work of the class. When you are telling others in the class what you have found out about these topics, remember that they must be able to hear what you are saying. You are not taking part in a family conversation or having a chat（闲谈）with friends — you are in a slightly unnatural situation where a large group of people will remain silent, waiting to hear what you have to say. You must speak so that they can hear you — loudly enough and clearly enough but without trying to shout of appearing to force yourself.
Remember, too, that it is the same if you are called to an interview whether it is with a professor of your school or a government official who might meet you. The person you are seeing will try to put you at your ease（轻松）but the situation is somewhat（一点儿）different from that of an ordinary conversation. You must take special care that you can be heard.
