【題目】 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 (發(fā)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 (消費(fèi)) 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 (膽固醇) 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 “l(fā)ean fish” (paragraph 5) mean “________”.

A.large fishB.fresh fish

C.fish that have little fatD.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

【答案】

【1】D

【2】C

【3】B

【解析】

本文是一篇說(shuō)明文。主要說(shuō)明了相關(guān)調(diào)查研究表明吃魚(yú)對(duì)人們健康的有積極的影響。吃魚(yú)多的國(guó)家，人們的心臟病死亡率相對(duì)較低。

【1】推理判斷題。根據(jù)第一段以及第三段的 But long before researchers have noticed that the incidence (發(fā)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 (消費(fèi)) averages more than 3 ounces.（ 但是，很久以前，研究者注意到，消費(fèi)掉更多魚(yú)的國(guó)家的心臟病發(fā)病略低于美國(guó)。心臟病死亡人數(shù)在減少，例如，在格陵蘭島的愛(ài)斯基摩人中，死于心臟病的人要少一些，愛(ài)斯基摩人每天消耗大約14盎司的魚(yú)，而日本人每天的魚(yú)消費(fèi)量平均超過(guò)3盎司）可推知，在魚(yú)類消費(fèi)量高的國(guó)家，心臟病死亡率較低。故選D。

【2】詞義猜測(cè)題。根據(jù)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.（在研究開(kāi)始時(shí)，魚(yú)類的平均消耗量約為每天三分之二盎司，吃瘦魚(yú)的男性比吃肥魚(yú)的男性要多）可知，than fatty fish 省略了men eating，more…than…將前后成分進(jìn)行比較，fatty意為“多脂肪的”，故lean fish與其形成對(duì)比，意為“脂肪少的魚(yú)”。故選C。

【3】主旨大意題。通讀全文以及第二段的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.（荷蘭的這項(xiàng)研究是三項(xiàng)人類研究之一，為長(zhǎng)期以來(lái)認(rèn)為吃魚(yú)有益健康的信念提供了強(qiáng)有力的科學(xué)支持，尤其是對(duì)心臟有益）可知，這篇文章主要內(nèi)容是相關(guān)調(diào)查研究表明吃魚(yú)對(duì)人們健康的有積極的影響。故選B。

【題目】 When people are rude to their co-workers or treat them badly, they probably don’t realize the unintended victims in the encounter could be the co-workers, children. Women who experience incivility in the workplace are more likely to engage in stricter, more authoritarian parenting practices that can have a negative impact on their children, according to the research presented at the annual meeting of the American Psychological Association.

“These findings reveal some previously undocumented ways that women, in particular, suffer as a result of workplace aggression,” said researcher Angela Dionisi, PhD, of Carleton University. This research also speaks to a previously unacknowledged group of indirect incivility victims, namely children.

Workplace incivility is any behavior that is disrespectful, impolite or otherwise goes against workplace standards of respect, according to coauthor Kathryne Dupre, PhD, of Carleton University. “We now know that the outcomes of workplace incivility are vast and negative,” said Dupre. Survey results showed that incivility in the workplace was associated with mothers feeling less effective as parents, which could help explain the increased need to engage in strict, controlling parenting behavior, said Dupre.

Authoritarian parents have high expectations from their children, with rules that they expect their children to follow unconditionally. At the same time, though, they provide very little in the way of feedback and severely punish any mistake, said Dupre. They tend to have lots of regulations and micromanage almost every aspect of their children’s lives, valuing discipline over fun.

“Research suggests that authoritarian parenting is more of a negative style of parenting as compared to other parenting styles. This style of parenting has been associated with a variety of negative child outcomes, including exhibiting aggressive behavior outside the home, being fearful or overly shy around others, having difficulty in social situations due to a lack of social competence,” she said.

【1】Which of the following is the closest in meaning to the underlined word “incivility” in Paragraph 1?

A.Rudeness.B.Panic.

C.Violence.D.Argument.

【2】Which of the following is NOT a feature of authoritarian parents?

A.They tend to be too strict with their children.

B.They set high standards for their children to reach.

C.They want to keep their children’s life under control.

D.They attach equal importance to discipline and fun.

【3】What is the main idea of the passage?

A.The cause of more authoritarian parents.

B.The harm of workplace incivility to children.

C.The different styles of parenting practices.

D.The effects of high expectations from children.

【題目】 Many of us think, wrongly, that the moon doesn’t change. For example, the Tang Dynasty poet Zhang Ruoxu once wrote that “Generations have come and passed away; From year to year the moons took alike, old and new.”

However, a new study published in the journal Nature Geoscience shows that the moon is in fact slowly shrinking over time. For the study, a group of US scientists examined and analyzed thousands of photographs taken by the NASA orbiter Lunar Reconnaissance Orbiter Camera (月球勘測(cè)軌道飛行器照相機(jī)) . They found that there were lots of faults (斷層) on the surface of the moon. These faults were formed by recent movement on the moon.

According to NASA, the moon is made up of pieces of rocks with a hot core (核) .The moon continued to expand as it was born. But in this process, it released energy and cooled down. Then it began to shrink, in a way comparable to the shrinking of a grape into a raisin (葡萄干) . Over the past several hundred million years, it has become 46 meters “skinnier”. But due to its hard and rocky crust (外殼) . the moon’s surface continues to push up, “Some of these quakes can be fairly strong around five on the Richter scale (里氏震級(jí) ) ,” said Thomas Watters, a senior scientist at the Smithsonian’s National Air and Space Museum in the US.

But does that mean the moon is a dangerous place that human shouldn’t try to explore and live on in the future? Maybe not, reported the Telegraph, “This isn’t anything to worry about. The moon may be shrinking, but not by much. It’s not going anywhere,” Watters comforted us.

The new discovery proves that the idea that the moon is a dead, boring place is wrong. “We have been to the moon and we’ve done some great science, but there is still a lot we don’t know. The moon is shrinking — we didn’t really realize that until recently. It’s a much more active and interesting place than we thought and we should explore that,” NASA scientist Nathan Williams said.

【1】Which point of view about the moon may the writer agree to?

A.It stays the same as before.B.It is becoming lightly smaller.

C.It is getting older and older.D.It has passed away.

【2】What can we learn about the moon from the third paragraph?

A.It has become 46 meters fatter due to expanding.

B.It has changed from a grape into a raisin in recent years.

C.It quakes even at seven on the Richter scale.

D.It has a hot core and releases energy during expanding.

【3】Who thinks that we needn’t worry about the moon?

A.Zhang Ruoxu.B.Thomas Watters.

C.Nathan Williams.D.The journalist.

【4】What does Nathan Williams think of the moon?

A.It is a dead and boring place.B.It has lots of faults on the surface.

C.It is valuable to do more science.D.It isn’t a place where we can live.
