Question

【題目】根據(jù)短文內(nèi)容，從下框的A-F選項(xiàng)中選出能概括每一段主題的最佳選項(xiàng)，并在答題卡

上將該選項(xiàng)涂黑。選項(xiàng)中有一項(xiàng)為多余選項(xiàng)。

A. Careful biological research B. The information of global warming C. Solution to the terrifying result D. Greater danger of extinction E. Examples of species in danger of extinction F. A shocking report

【1】

The earth is getting warmer. People burn coal, oil and gas and this produces carbon dioxide, methane (沼氣) and nitrous oxide. These gases, called “greenhouse gases”, prevent the heat of the sun from leaving the earth’s upper atmosphere and this makes the earth warmer.

【2】

A few weeks ago a group of scientists produced a report about global warming and the natural world. They wanted to find out if global warming was dangerous for plants and animals. According to what they found, the scientists say that during the next 50 years about 25% of land animals and plants will become extinct. More than a million plant and animal species will be extinct by 2050.

【3】

More than 10% of all plants and animals will become extinct. It is too late to save many plants and animals because of the greenhouse gases that are already in the atmosphere. But the scientists say if we control greenhouse gases now, we could save many more plants and animals from extinction.

【4】

The scientists studied some regions of the world with a very rich biology. These regions were Europe, Australia, Central and South America and South Africa. Their studies showed that species living in mountainous areas had a better chance of survival because they could move uphill to get cooler. In flat areas, such as deserts, plants and animals would have to move a very long distance to get cooler, so they are in greater danger of extinction.

【5】

The scientists found that half of the 24 species of butterflies they studied in Australia would soon become extinct. 60% of the species in the Kruger National Park in South Africa would also die out, and more than 100 of the 300 South Africa plant species they studied would also become extinct. One of the plants in danger of extinction is the national flower of South Africa, the King Protea. They studied 163 tree species in the Cerrado region of Brazil and found that 70 would become extinct. Many of the plants and trees that live in this region live nowhere else in the world. In Mexico, they studied 1,870 species and found that more than 30% of these were in danger of extinction.

Answer 1

【答案】

【1】B

【2】F

【3】C

【4】A

【5】E

【解析】

試題分析:目前，由于人們?nèi)紵�煤、油等而排放出的溫室氣體導(dǎo)致了全球的變熱。幾周前一群科學(xué)家對(duì)此做了一份分析報(bào)告。他們想要證明是否全球變暖對(duì)植物和動(dòng)物有害，根據(jù)他們的發(fā)現(xiàn)，在以后的50年內(nèi)，大約會(huì)有25%de 陸地動(dòng)植物會(huì)滅絕。

【1】B考查對(duì)文章的理解和歸納能力。本段對(duì)全球氣溫變暖進(jìn)行解釋，和B選項(xiàng)內(nèi)容相符，選B。

【2】F】考查對(duì)文章的理解和歸納能力。從這段的內(nèi)容和第一句話A few weeks ago a group of scientists produced a report about global warming and the natural world.可知本段介紹了報(bào)告的內(nèi)容，信息詞report，選F。

【3】C考查對(duì)文章的理解和歸納能力。根據(jù)本段末句可知這段提出了這種問(wèn)題的解決辦法，選C。

【4】A考查對(duì)文章的理解和歸納能力。由本段第一句話The scientists studied some regions of the world with a very rich biology.可知這是從生物角度的仔細(xì)分析，和A選項(xiàng)中biological相符，故選A。

【5】E考查對(duì)文章的理解和歸納能力。本段列舉了很多即將面臨滅絕的動(dòng)物，由此判斷選E。
