【题目】Most respected scientists agree that we need to find another source of energy- and quickly. If we continue to burn oil and pump carbon into the atmosphere, then the effects on global climate will lead to global disasters even before the oil disappear.

The British government has set a target of a 20 percent reduction in carbon emission by 2010. Central to this policy is the search for alternative, renewable forms of energy production---and this is where the serious disagreement among scientists begins.

Here, two people active in the debate about wind farms give their points of view.

Simon Shearman

“First, a few facts about wind power. Wind is one of the cheapest of the new, renewable forms of energy. It is extremely safe---no member of the public has ever been injured at a wind farm. The shallow waters around Britain are the windiest in Europe---ideal locations for wind farms and, by 2010, up to ten percent of the electricity used in the UK could be produced by wind power. I find it annoying and frustrating that the biggest objection that opponents of wind farms can come up with is that the crisis of global warming is real and something must be done urgently.”

Alice Evans

“The simple, obvious fact is that wind turbines(涡轮机) cannot generate electricity if the wind is too light or too strong and it often is. Many scientists estimate that wind turbines generally produce only 30 percent of their capacity(容量). This is not a reliable enough supply to enable us to close down conventional power stations. In fact, wind power can’t keep up with the growth of the demand for electricity, let alone replace other sources of power.”

It’s a topic that is causing heated debate around the country---but one we must address before it’s too late---before the oil runs out.

【1】Many scientists have different opinions on the search for a renewable energy because ______.

A. they think fossil fuels are everlasting.

B. British government’s target is not realistic.

C. they are not sure in finding the clean and renewable energy.

D. the technology is not advanced enough.

【2】We can learn from the passage that ______.

A. there won’t be a global disaster before the world runs out of oil.

B. the British government wants people to use 20 percent less oil by 2010.

C. Alice Evans supports the idea of wind power.

D. Simon Shearman thinks Britain a particularly suitable place for wind farms.

【3】If we generate electricity with wind turbines, _______.

A. a light wind will do.

B. we cannot make full use of the capacity.

C. a strong wind will do

D. we’ll have enough electricity.

【4】What can we learn from the last paragraph?

A. Wind power is a good solution to energy crisis.

B. We’re experiencing the oil crisis now.

C. We should find alternative energy for oil as soon as possible.

D. There is no need for us to worry about energy problem.

【答案】

【1】C

【2】D

【3】B

【4】C

【解析】

试题分析:本文讲述寻找石油的可再生清洁能源成为燃眉之急,然而这也是众多科学家分歧之所在。针对风能,科学家Simon认为其是较好的可替代再生能源,而科学家Alice则认为其发电量无法满足需求。

【1】C细节理解题。根据第二段最后一句Central to this policy is the search for alternative, renewable forms of energy production---and this is where the serious disagreement among scientists begins.政策的中心就是找到一个可替代的,可再生的能源,这也是引起科学家们激烈争论的地方,即他们还未确定找到可再生清洁能源,故选C

【2】D细节理解题。根据第四段第四句The shallow waters around Britain are the windiest in Europe---ideal locations for wind farms英国周围的浅水区在欧洲是最有利风力发电的,对于风力发电厂是一个理想的地方,故选D

【3】B细节理解题。根据倒数第二段第二句Many scientists estimate that wind turbines generally produce only 30 percent of their capacity许多科学家评估风力涡轮机仅能产生容量30%的电,可知不能充分利用其容量,故选B

【4】C细节理解题。根据最后一句but one we must address before it’s too late---before the oil runs out但有一点我们必须强调,不能太迟,要在石油耗尽之前,即我们要尽快找到石油的替代能源,故选C

【题目】One might expect that the ever-growing demands of the tourist trade would bring nothing but good for the countries that receive the holiday-makers. Indeed, a rosy picture is painted for the long-term future of the holiday industry. Every month sees the building of a new hotel somewhere. And every month another rock-bound Pacific island is advertised as the “last paradise (天堂) on earth”.

However, the scale and speed of this growth seem set to destroy the very things tourists want to enjoy. In those countries where there was a rush to make quick money out of seaside holidays, over-crowded beaches and the concrete jungles of endless hotels have begun to lose their appeal.

Those countries with little experience of tourism can suffer most. In recent years, Nepal set out to attract foreign visitors to fund developments in health and education. Its forests, full of wildlife and rare flowers, were offered to tourists as one more untouched paradise. In fact, the nature all too soon felt the effects of thousands of holiday-makers traveling through the forest land. Ancient tracks became major routes for the walkers, with the consequent exploitation (开发) of precious trees and plants.

Not only can the environment of a country suffer from the sudden growth of tourism. The people as well rapidly feel its effects. Farmland makes way for hotels, roads and airports; the old way of life goes. The one-time farmer is now the servant of some multi-national organization; he is no longer his own master. Once it was his back that bore the pain; now it is his smile that is exploited. No doubt he wonders whether he wasn’t happier in his village working his own land. Thankfully, the tourist industry is waking up to the responsibilities it has towards those countries that receive its customers. The protection of wildlife and the creation of national parks go hand in hand with tourist development and in fact obtain financial support from tourist companies. At the same time, tourists are being encouraged to respect not only the countryside they visit but also its people.

The way tourism is handled (处理) in the next ten years will decide its fate and that of the countries we all want to visit. Their needs and problems are more important than those of the tourist companies. Increased understanding in planning worldwide tourism can preserve (保护) the market for these companies. If not, in a few years’ time the very things that attract tourists now may well have been destroyed.

【1What does the author actually mean in the last sentence of Paragraph 1?

AThe Pacific island is a paradise.

BThe Pacific island is worth visiting.

CThe advertisement is not persuasive

DThe advertisement is not impressive.

【2The example of Nepal is used to suggest ______.

BThe improvement of services.

CThe promotion of new products.

DThe management of tourism.

【4The author’s attitude towards the development of the tourist industry is ______.

Cdoubtful DNegative

【题目】Picky eaters may have good reasons for their behaviour. No matter why your child has become picky, how you handle the situation can affect his or her future. Therefore, you should know the following reasons for picky children first of all.

Neophobia is common in children; it often happens at the dinner table. Some children just refuse to try new food because they don’t know what it will taste like, while others dislike new food before even smelling it. Some children take it to the extreme(极端) and will only eat a few foods that they like. Psychologist Dr. Elizabeth Capaldi says that, by the time children reach the age of two, they have formed their own eating habits that they don’t want to be disturbed by new offerings at the table.

A newly published study led by Dr. Lucy Cooke of University College London showed that picky eating in children results from genetic(遗传的) and environmental causes. The research, which followed the eating habits of 5,390 pairs of twins between the ages of 8 and 11, found that about 75% of the neophobia in the children was from their parents, while 25% was due to the influence of environment.

Children grow at a high speed during their first year, but that fast-paced growth tends to slow down by their second year. When children are not experiencing one of those fast growth periods, their body needs less energy; and that results in a smaller appetite(胃口). When children are not hungry, they tend to enjoy only food they like. They refuse new food and food that is not their favourite. Some children will limit the amount of food to only one kind, like hamburgers or pancakes, leaving all the other foods untouched.

In some cases, many real reasons why a child behaves as a picky eater exist. About 5% of children who are 10 years of age or younger have some type of neurological dysfunction(神经机能障碍) that influences their eating habits. These children may be easily hurt by some special smells, or their brain may not be able to process such sensory information properly.

A.the fear of something new or unknown

B.the worry about the amount of new food

C.the feeling of eating at the dinner table

D.the fear of eating tasty food

【2What can we learn about the study led by Dr. Cooke?

A.It paid more attention to the environmental effects on children’s eating habits.

B.It followed the eating habits of 5,390 children aged between 8 and 11.

C.It showed that genetics greatly affect children’s eating habits.

D.It suggested that parents should have good eating habits.

【3The fourth paragraph mainly tells us that_______.

A.children’s growth speed stays the same in the first two years

B.children develop their own diet when they grow up

C.children tends to eat less when they grow up

D.children’s growth has an effect on their diet

【4The reason mentioned in the last paragraph has something to do with a child’s_______.
