A small piece of fish each day may keep ...

    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 (消耗) at least an ounce (盎司) 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 long before researchers 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 (消费) 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.

1.We can infer from the passage that there are fewer heart disease deaths ________.

A.in highly-developed countries

B.in countries of the yellow-skin race

C.in the countries with good production of fish

D.in the countries with high consumption of fish

2.The underlined words “lean fish” (paragraph 5) mean “________”.

A.large fish B.fresh fish

C.fish that have little fat D.fish that live in salt water

3.The passage is mainly about ________.

A.the changes in people’s diet

B.the effect of fish eating on people’s health

C.the high incidence of heart disease in some countries

D.the daily fish consumption of people in different cultures

 

1.D 2.C 3.B 【解析】 本文是一篇说明文。主要说明了相关调查研究表明吃鱼对人们健康的有积极的影响。吃鱼多的国家,人们的心脏病死亡率相对较低。 1.推理判断题。根据第一段以及第三段的 But long before researchers 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 (消费) averages more than 3 ounces.( 但是,很久以前,研究者注意到,消费掉更多鱼的国家的心脏病发病略低于美国。心脏病死亡人数在减少,例如,在格陵兰岛的爱斯基摩人中,死于心脏病的人要少一些,爱斯基摩人每天消耗大约14盎司的鱼,而日本人每天的鱼消费量平均超过3盎司)可推知,在鱼类消费量高的国家,心脏病死亡率较低。故选D。 2.词义猜测题。根据第五段的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.(在研究开始时,鱼类的平均消耗量约为每天三分之二盎司,吃瘦鱼的男性比吃肥鱼的男性要多)可知,than fatty fish 省略了men eating,more…than…将前后成分进行比较,fatty意为“多脂肪的”,故lean fish与其形成对比,意为“脂肪少的鱼”。故选C。 3.主旨大意题。通读全文以及第二段的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.(荷兰的这项研究是三项人类研究之一,为长期以来认为吃鱼有益健康的信念提供了强有力的科学支持,尤其是对心脏有益)可知,这篇文章主要内容是相关调查研究表明吃鱼对人们健康的有积极的影响。故选B。

    It may help you to know that there is no such thing as a perfect speech. At some point in every speech, every speaker says something that is not understood exactly as he has planned. Fortunately, such moments are usually not obvious(明显的) to the listeners. Why? Because the listeners do not know what the speaker plans to say. They hear only what the speaker does say. If you lose your place for a moment, wrongly change the order of a couple of sentences, or forget to pause at a certain point, no one will be any the wiser. When such moments occur, don't worry about them. Just continue as if nothing happened.

Even if you do make an obvious mistake during a speech, that doesn't really matter. If you have ever listened to Martin Luther King's famous speech---"I have a Dream", you may notice that he stumbles(结巴) over his words twice during the speech. Most likely, however, you don't remember. Why?  Because you were fixing your attention on his message rather than on his way of speech-making.

People care a lot about making a mistake in a speech because they regard speech-making as a kind of performance rather than as an act of communication(交流). They feel the listeners are like judges in an ice-skating competition. But, in fact, the listeners are not looking for a perfect performer. They are looking for a well-thought-out speech that expresses the speaker's ideas clearly and directly. Sometimes a mistake or two can actually increase a speaker's attractiveness by making him more human.

As you work on your speech, don't worry about being perfect. Once you free your mind of this, you will find it much easier to give your speech freely.

1.The underlined part in the first paragraph means that no one will ______.

A.be smarter than you B.notice your mistakes

C.do better than you D.know what you are talking about

2.You don't remember obvious mistakes in a speech because ______.

A.your attention is on the content

B.you don't fully understand the speech

C.you don't know what the speaker plans to say

D.you find the way of speech-making more important

3.It can be inferred from the passage that ______.

A.giving a speech is like giving a performance

B.one or two mistakes in a speech may not be bad

C.the listeners should pay more attention to how a speech is made

D.the more mistakes a speaker makes, the more attractive he will be.

4.What would be the best title for the passage?

A.How to Be a Perfect Speaker B.How to Make a Perfect Speech

C.Don't Expect a Perfect Speech D.Don't Expect Mistakes in a Speech

    The 92-year-old, thin, calm and proud lady, who is fully dressed each morning by eight o’clock, even though she is nearly blind, moved to a nursing home today.

Her husband of 70 years recently passed away, making the move necessary. After many hours of waiting patiently in the hall of the nursing home, she smiled sweetly when told her room was ready.

As she walked slowly to the elevator, I provided a true description of her tiny room, including the old sheets that had been hung on her window. “I love it,” she said with the happiness of an eight-year-old having just been presented with a new puppy.

“Mrs. Jones, you haven’t seen the room…just wait.”

“That doesn’t matter,” she replied. “Happiness is something you decide ahead of time. Whether I like my room or not doesn’t depend on how the furniture is arranged. It’s how I arranged my mind. I have already decided to love it. It’s a decision I make every morning when I wake up. Each day is a gift, and as long as my eyes open I’ll focus on the new day and all the happy memories I’ve stored away.” She went on to explain, “Old age is like a bank account. You take what you’ve put in. So, my advice to you would be to put in a lot of happiness in the bank account of memories. Thank you for your part in filling my memory bank.” And with a smile, she said, “All my memories are happy ones.”

Mrs. Jones was always happy in the nursing home and she died at the age of 108.

1.We can infer from the passage that the author ________.

A.is one of Mrs. Jones’ children B.is a relative of Mrs. Jones

C.works in the nursing home D.is the owner of the nursing home

2.The room in which the old lady will live ________.

A.is very comfortable B.is fairly big

C.isn’t well equipped D.is equipped with new furniture

3.Mrs. Jones was very happy when told about her room because she ________.

A.couldn’t see what her room was like

B.thought the nursing home was her home

C.would have to live in the nursing home

D.had already made up her mind to be happy

4.Which of the following words can best describe Mrs. Jones?

A.Proud. B.Cheerful. C.Determined. D.Honest.

    There are many fun, free activities that you can do as a family. All that is required is a bit of imagination and some time. And the best part is that these are the kind of fun, family memories a child will remember for a lifetime.

Family Game Night

Kids often get games for Christmas or birthdays, and would love to have a chance to play with their family. Or, make up some games of their own. Charades (字谜游戏) is a fun game that will challenge children to use their imagination. Divide the family into teams and let each team come up with words and the other has to act out.

Family Art Time

Pick some time for the family to sit down and come up with their own art. It doesn’t need to be just a drawing—take some old magazines, let the kids cut out pictures and paste them into their own shape. Or let them use leaves, branches and whatever else they can find to make something from their imagination.

Family Picnic

Taking the family for a picnic is a great way for some fun that doesn’t cost any money. If the weather is nice, take them to a park or playground and let them have a day of playing.

Family Field Trip

A family field trip doesn’t have to cost a cent. Ask a nearby farm if you can bring your kids out for a tour and to see some of the animals. Or take them to a park to find certain items from nature. Ask a local business if you could bring the family for a tour to see how things work—you might be surprised at the number of people who would be excited to share what they do with others, and it could be an interesting lesson for kids.

1.When playing the game charades, kids are supposed to ________.

A.prepare some cakes for each other

B.be quick to follow others’ actions

C.sing a song for each other in turn

D.connect actions with certain words
