【題目】Australia’s koalas could be wiped out within 30 years unless urgent action is taken to stop the losing in population, according to researchers They say development, climate change and bushfires have all combined to reduce the number of wild koalas sharply. The Australian Koala Foundation said a recent survey showed the population could have dropped by more than half in the past six years. Previous estimates (估計) put the number of koalas at more than 100,000, but the latest calculations (計算) suggest there could now be as few as 43,000.

The foundation collected field data from 1,800 sites and 80,000 trees to calculate the numbers. In one area in northern Queensland estimated to have 20,000 koalas a decade ago, a team of eight people could not find a single animal in four days of searching.

The foundation said besides problems caused by cutting down forests, hotter and drier conditions because of global warming had reduced the nutritional (營養(yǎng)的) value of their staple food, eucalyptus leaves, leading to poor nutrition for them.

Koalas, which live in the forests in Australia’s east and south, are very fussy (愛挑剔的) about what types of the leaves they eat.

Foundation chief Deborah Tabart said: “The koalas are missing everywhere we look. It’s really no tree, no me. If you keep cutting down trees you don’t have any koalas.”

She is hoping the new figures will persuade the government’s Threatened Species Steering Committee (TSSC) to list the koala as threatened. But committee chairman Bob Beeton said a decision was not likely recently and the koala’s status as one of the country’s favourite animals would not be a factor. “There’s a number of species which are attractive and people have special feelings towards them. We don’t consider that,” Mr Beeton was reported as saying by the AFP agency.

【1】The writer gives the example of the area in northern Queensland in Paragraph 3 to show that _____.

A. the forests are being damaged heavily

B. the environment is being polluted seriously

C. the number of koalas is dropping quickly

D. koalas usually live in wild mountainous areas

【2Global warming is an important cause of koalas’ reduction because _____.

A. koalas can hardly stand the hot weather

B. koalas cannot get enough water to drink

C. the leaves koalas eat are losing nutritional value

D. the leaves koalas eat cannot grow in hot weather

【3According to Bob Beeton, _____.

A. koalas are his favourite animals

B. a decision will be made to protect koalas

C. they needn’t pay special attention to koalas

D. koalas needn’t be protected at all

【答案】

【1】C

【2】C

【3】C

【解析】

試題分析:澳大利亞的koalas數(shù)量變少,是由于地球變暖,葉子的營養(yǎng)價值減少。吸引人的動物有很多種類,人們對他們有特殊的感情,不用太關(guān)注koalas。

【1】C推理判斷題。根據(jù)第三段第二句中的a team of eight people could not find a single animal in four days of searching.在四天的搜尋中,一個八人的小組找不到一個動物。因此可推斷出koalas的數(shù)量正在快速下降。故選C。

【2】C細節(jié)理解題。根據(jù)第四段global warming had reduced the nutritional (營養(yǎng)的) value of their staple food, eucalyptus leaves, leading to poor nutrition for them. 地球變暖減少了樹葉的營養(yǎng)價值。故選C。

【3】C推理判斷題。根據(jù)最后一段最后兩句There’s a number of species which are attractive and people have special feelings towards them. We don’t consider that,吸引人的動物有很多種類,人們對他們有特殊的感情。我們不用考慮那個。即不用考慮koalas的變少。故選C。

【題目】根據(jù)短文內(nèi)容,從下框的A—F選項中選出能概括每一段主題的最佳選項。選項中有一項為多余選項。

E

A. Don’t be afraid of risks.

B. Find ways to solve problems.

C. Learn from successful people.

D. Don’t give up easily.

E. Know the meaning of success.

F. Enjoy facing your failure.

【1】You cannot have success if you don’t know what it means to you. Set clear goals and be realistic. Your standards should be specific or else you will spend your entire time chasing after a vague goal. For example, you want to be good at your job. However, this is not a specific goal. Instead, specify this goal as: “My goal is to only be late for work five times per year, at the most.” This is a specific goal that when achieved, give you a sense of satisfaction and completion, making you feel successful and confident.

2Look around---who has the success that you envision(想象)for yourself? What are they doing? How do they come near a successful life? Become their students. Ask them for advice. Spend time around them, if you can. Learn from them. They will bring you much useful experience.

3Successful people think big and act big. It can be scary to do, but if you don’t, then how will you ever be successful? Don’t wait for opportunities. Dig them out. Successful people make big investments (in their careers, in their business, in their education) and all investments involve some degree of risk. Study your risks, and be brave.

4People who are successful like solving problems and answering questions. No matter where you are or what you are doing, look around and try to think of ways you can find, for example, what are people struggling with or complaining about? How can you make life easier for them in an effective way? Can you redesign or reorganize some aspects of the situation so that things can run more smoothly?

5You should learn to persist. It is also the key factor to success. When asked about his 10,000 failed attempts to develop a storage battery, the prolific(多產(chǎn)的)American inventor Thomas Edison replied: “I have not failed; I’ve just found 10,000 ways that won’t work. So, if your first attempt didn’t work, don’t quit and don’t give up.”
