【題目】 You have probably heard that Japan has among the highest life expectancy(預(yù)期壽命) in the world and that the island of Okinawa(沖繩) has the greatest concentration(濃度) of centenarians(百歲老人). But do you know that two-thirds of the centenarians are still functioning independently? That means they are in their own homes, cooking their own meals and living their lives fully - at about 100 years old!

The elders there are less likely than their counterparts in the United States to have heart disease, dementia(癡呆) or certain cancers. Their bones are stronger than those of similarly aged people around the world. Many of these residents are the subjects of one of the largest studies of centenarians ever conducted. Since 1976, nearly a thousand centenarians on the islands have been studied.

More than anything, the Okinawa diet has long captured the headlines. Before knowing what the Okinawans eat, there is a valuable lesson in how they eat.

Remember this term: hara hachi bu. It is translated into English as “Stop eating when you are 80% full.” With hara hachi bu, the philosophy is that you should still be a little hungry when you push the plate away. You are also advised to reduce your portion(食物的分量) sizes, use smaller plates and eat more slowly.

There is a basic biological (生物學(xué)的) reason this works. It takes about 20 minutes for the stomach to send signals to the brain that it is full. Unfortunately, most people can shovel down another several hundred calories in that short time. Instead, if you push the plate away and just wait, you will have eaten less and still feel satisfied.

Eating less is associated with longevity, but of course, that also depends on what you eat. Okinawans typically eat seven different fruits and vegetables and 18 different foods a day, and more than 200 different foods and spices regularly in their overall diet.

However, the younger generations are eating more meat and fast food instead of fish and soy. The elderly there are still widely revered(崇敬), but there are fewer of them, and they are less often living to 100 than in decades past.

1What is the key to the high life expectancy in Okinawa?

A.What they eatB.How they eat

C.Where they liveD.When they exercise

2Which of the following has the closest meaning to the underlined part “shovel down” in Paragraph 5?

A.fill inB.put down

C.fill outD.push away

3Which of the following statements about Okinawa is true?

A.The elderly are in bad need of mutual respect.

B.There are an increasing number of the elderly.

C.The younger generations have a varied diet.

D.Things are starting to change for the worse.

4Which could be the best title for the passage?

A.Eat less to live longer.

B.Healthy diets build longevity.

C.The Okinawa: a place of longevity.

D.Improve life expectancy? Slow down.

【答案】

1B

2A

3D

4A

【解析】

本文是說明文。日本沖繩島上的長壽老人密度最大。文章分析其中的原因是他們的飲食習(xí)慣:吃到八成飽就不再吃了,食物種類多樣。

1

細(xì)節(jié)理解題。根據(jù)第三段中“ there is a valuable lesson in how they eat.(他們怎么吃給人們上了寶貴的一課)”可知,沖繩島上的老人長壽比率高的關(guān)鍵是他們的飲食怎么吃。故選B 項(xiàng)。

2

詞義猜測題。根據(jù)第五段中劃線詞前一句提到“胃需要大約20分鐘才能向大腦發(fā)出飽腹的信號”;根據(jù)劃線詞后的部分“…another several hundred calories in that short time”,可以推斷該句句意為“大多數(shù)人可以在這么短的時(shí)間內(nèi)再吃進(jìn)幾百卡路里”。因此可以推測“shovel down”的意思與“fill in”相近;“shovel down”本意為“胡亂塞進(jìn)”。故選A項(xiàng)。

3

細(xì)節(jié)理解題。根據(jù)文章最后一段中“The elderly there are still widely reveredbut there are fewer of them, and they are less often living to 100 than in decades past.( 老人還是受到尊敬,但是老人比較少了。與過去幾十年相比,他們活到100歲的幾率降低了。)”可以推斷,在沖繩島上,老人的長壽情況沒有以前那么好了,開始變糟。故選D項(xiàng)。

4

主旨大意題。文章分析了日本沖繩島上的老人長壽的主要原因是他們的飲食習(xí)慣。文章第四段中提到“Stop eating when you are 80% full”當(dāng)你80%飽的時(shí)候就停止進(jìn)食;第六段中提到“Eating less is associated with longevity少吃多壽”,都是關(guān)于少吃和長壽的關(guān)系。因此文章的標(biāo)題應(yīng)為“少吃可以長壽”。故選A項(xiàng)。

Archaeologists have long thought that stone ships served as graves for one or several individuals, and have even been viewed as death ships 1 to take the dead to living eternally. However, a new study conducted by researchers from the University of Gothenburg shows a different picture. It suggests Bronze Age stone monuments in the form of ships were built by sailors as a symbol of their practices at sea.

The study indicates that the stone ships and the activities that took place there point to people who were 2 focused on practices at sea. Details found within the stone structures show they were built to 3 real ships. The stone ships offer up 4 about the ship-building techniques of the time and about the ships that sailed on the Baltic Sea during the Bronze Age.

“These consist of areas that 5 hill forts and are located near easily 6 points in the landscape—that is, near well-known waterways leading inland,” Wehlin, head of the team, said. “While these areas have previously been thought to be much younger, recent age 7 have dated them to the Bronze Age.”

Archaeologists have believed that bronze was 8 to Scandinavia from the south, and recent analyses have helped confirm this notion. However, the people who distributed the bronze objects are rarely 9 in these thoughts.

“One reason why the meeting places of the Bronze Age are not discussed very often is that we haven’t been able to find them,” Wehlin said. “This is in 10 contrast to the trading places of the Viking Age, which have been easy to locate as they left behind such rich archaeological material.”

Many trees and shrubs change color in fall. For years, scientists have worked hard to understand the changes that happen to them. They find that three factors 1 fall's colorful farewell — leaf pigments (色素), length of night, and weather. The timing of the color change is mainly regulated by the increasing length of night. None of the other 2influences, such as temperature, rainfall, food supply, are as unchanging as the 3increasing length of night during fall. As days grow shorter, and nights grow longer and cooler, biochemical 4 in leaves begin to paint the landscape with an explosion of colors. And Nature puts on one of its most splendid 5 of beauty.

The timing of the color change6 by species. Some species in southern forests can become vividly colorful in late summer while all other species are still vigorously green. Oaks put on their colors long after other species have already shed their leaves. These differences in timing among species seem to be genetically 7, for a particular species, whether on a high mountain or in warmer lowlands, will change color at the same time.

However, some species are evergreen. Pines, for example, are green all the year round because they have toughened up. They have developed over the years a needle-like or scale-like foliage (綠葉植物), which is8 with a heavy wax coating. And the liquid inside their cells contains cold-resistant elements. So the leaves of evergreens can safely withstand (經(jīng)受住) all but the most 9winter conditions, such as those in the Arctic.

【題目】DirectionsComplete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need.

Cure isn’t a word normally used in the 1 of AIDS. For most of the 35 years since HIV, the virus responsible for the disease, was first identified, doctors have viewed the notion of a cure as more 2 than fact.

That’s because HIV is a virus unlike any other. It disables the very immune cells that are 3 to destroy it, carrying out the ultimate deadly ambush(埋伏)whenever the guard of immune 4 comes down, months or sometimes even years later.

Yet for the first time in the HIV epidemic that 5 affects nearly 37 million people worldwide, some experts are starting to aim for a cure cautiously. The National Institutes of HealthNIHis funding HIV cure efforts and advocacy groups like amfAR are also 6 resources into not just treating HIV, but also finding ways to eliminate it completely.

“Absolutely HIV can be cured,”says Rowena Johnston, vice president and director of research for amfAR.“The question is how.”

Doctors today have no trouble keeping HIV under control in people who are infected, thanks to antiretroviralARVdrugs, which stop the virus from replicating(復(fù)制). If it is not making more copies of itself. HIV cannot spread to infect new cells. That can 7 into healthier, longer lives for people who are HIV-positive.

Powerful as the current drug treatments are, they can’t actually 8 the body of infected cells. For self-preservation, some HIV lies latent(潛伏性的)inside certain immune cells. These are the viruses that come coaring back when people stop taking their medications.

But the latest report this month revealed the strongest evidence that these latent viruses can be activated and eliminated, at least in animals. Dr. Dan Barouch and his colleagues showed that a drug that stimulates the immune system, 9 with a powerful antibody, prevented HIV from roaring back in five of 11 animals, six months after they stopped taking ARVs.“I think our data raises the 10 that an intervention achieving a functional cure is possible,”says Barouch.
