Question

The smallest animal with a backbone（脊椎） known to science, a fish from the carp family, has been discovered in the peat swamps （沼澤）of Indonesia. Mature（成熟的）females of the fish species （種類）Paedocypris reach just 7.9mm in length.

         The species was discovered in the highly acidic (酸性的) peat swamps of the Indonesian island of Sumatra by a team led by Ralf Britz, a zoologist at the Natural History Museum in London.

         “This is one of the strangest fish that I’ve seen in my whole career,” Dr Britz said. “It’s tiny, and it lives in acid. I hope that we’ll have time to find out more about them before their habitat disappears completely.”

         The species lives in dark tea-colored swamp waters, which are 100 times more acidic than rainwater. Although these swamps were once thought to be inhabited by very few animals, recent research has shown that they are home to a highly different range of species that occur nowhere else.

         The peat swamps were damaged by forest fires in 1997, and are also threatened by agriculture. The scientists behind the discovery said that several populations of Paedocypris had already been lost.

         “Many of the peat swamps we surveyed（調(diào)查）throughout South-East Asia no longer exist,” Dr Britz said. “Populations of all the miniature（微型的）fish of peat swamps have decreased or disappeared.”

         Details of the discovery are published today in the journal Proceedings of the Royal Society of London, Series B.

1.64.Which of the following would be the best title for the passage?

C.Strange Species

D.The Smallest Backbone Animal

2.65.Where does the smallest backbone animal live?

A.It lives in highly acidic rainwater.

B.The species lives in the acidic waters of dark tea-coloured swamps.

C.It was put in the Natural History Museum in London.

D.Its habitat disappears completely. 

3.66.According to the passage, the forest fires in 1997 have led to the fact that______.

A .many places where these animals lived have been damaged

B.the population of the specieshas increased

C.there are many animals in the acidic peat swamps today

D. agriculture doesn’t affect the living space of these animals

4.67.Dr Britz’s words imply______.

A.the habitat will be more after a period of time

B.many peat swamps that they surveyed have already survived

C.he wants to find more miniature fishes before their habitat disappears

D. he wants to have further research

【解析】

試題分析：

【文章大意】本文是一篇科普類文章。文章講述了瀕臨滅絕的最小的脊椎動(dòng)詞的生存環(huán)境及目前的情況。

1.D考查文章的標(biāo)題。根據(jù)文章的第一段中的The smallest animal with a backbone（脊椎） known to science, a fish from the carp family, has been discovered in the peat swamps （沼澤）of Indonesia.可知，這是文章的中心句。由中心句可知文章主要講的是：最小的脊椎動(dòng)物。故選D。

2.B考查細(xì)節(jié)理解。根據(jù)文章第四段中的The species lives in dark tea-colored swamp waters, which are 100 times more acidic than rainwater.可知，這種物種生活在深茶色的沼澤中，其中的水是雨水的酸度的100倍。故選B。

3.A考查細(xì)節(jié)理解。根據(jù)文章倒數(shù)第三段中的The peat swamps were damaged by forest fires in 1997, and are also threatened by agriculture.可知A正確。其他三項(xiàng)與文章內(nèi)容不符。

4.D考查推理判斷。根據(jù)文章第三段中的I hope that we’ll have time to find out more about them before their habitat disappears completely.可知，Dr Britz想進(jìn)一步了解它們，在他們完全滅絕之前。故選D。
