20.A new species of snailfish was found at a record breaking depth of 8,145meters.It was found at the bottom of the Mariana Trench(海溝),the deepest site on earth.
The new species was recorded at a depth of 8,145meters.It broke the former depth record,set in 2008,by nearly 500meters."This really deep-sea fish does not look like anything we have seen before,and nor does it look like anything we know of,"Alan Jamieson from the University of Aberdeen said."It is unbelievably easy to be damaged,with large wing-like fins (鰭)and a head looking like a cartoon dog."
The Mariana Trench sits nearly 11,000meters below sea level in the Pacific Ocean.There very few large animals are found.It's too cold and dark for most fish.However,new robotic technology is allowing researchers to explore this extreme environment,which has been long thought too bad for any life to exist.Along with the new species of snailfish,researchers filmed several other rarely seen creatures.They include super giant amphipods.They can measure a foot or more in length and are often referred to as the uinsects of the sea".
Larger animals,like rattails and cusk-eels,live in shallower waters of 5,000to 6,500meters.Super giant amphipods live at mid-depths of 6,500to 8,000meters.The newly found snailfish lives at depms greater than 8,000meters.
In 2012,director James Cameron became the first person to visit the bottom of the trench in more than 50years.A year later,scientists published research showing that the trench has many microbes(微生物)that are able to survive on the remains of dead animals,water plants,and other microbes that float down the trench slopes (斜坡).

A.It doesn't look like any commonly seen species.
B.It can easily survive in a new environment.
C.It likes travelling at different depths underwater.
D.It has very beautiful appearance.

D.Largest animals,
34.What was the result of the scientist's research about the trench in 2013?D
A.There were many dead animals there.
B.James Cameron was the first to Teach there.
C.Life hardly survives there,
D.There was life down there.
35.What's the main idea of the passage?A
A.Researchers discovered life in the deepest ocean.
B.A new species of snailfish was found at the deepest site on earth.
C.Animals are able to the remains of dead animals in the sea.
D.The bottom of the Mariana IVeneh was the deepest site on earth.

解答 32-35.AADA
32題答案:A考查細節(jié)推理,根據(jù)文章中的This really deep-sea fish does not look like anything we have seen before,and nor does it look like anything we know of這種深海魚不像我們之前看過的任何東西,也不像我們所知道的任何東西.可知本題答案為A選項.
33題答案:A考查細節(jié)推理,根據(jù)文章第二段的Larger animals,like rattails and cusk-eels,live in shallower waters of 5,000to 6,500meters.Super giant amphipods live at mid-depths of 6,500to 8,000meters.The newly found snailfish lives at depms greater than 8,000meters.諸如rattails 和 cusk-eels一樣大一點的動物生活在5000-6500的淺水,超大的端足類生活在6500-8000米的中等深度,新發(fā)現(xiàn)的蝸牛魚生活在8000米以下.以及倒數(shù)第三段的They include super giant amphipods.They can measure a foot or more in length and are often referred to as the uinsects of the sea".他們包括超大的端足類動物,它們的長度可以超過一英尺而且通常被認(rèn)為是海中最大的昆蟲.可知A選項的動物生活在最淺處,故本題答案為A選項.
34題答案:D考查細節(jié)推理,根據(jù)文章最后一段的A year later,scientists published research showing that the trench has many microbes(微生物)that are able to survive on the remains of dead animal一年后,科學(xué)家發(fā)表的研究表明溝渠里含有很多微生物--這些微生物能夠靠動物的死尸殘留物生存.可知本題答案為D選項.
35題答案:A考查主旨大意,本文主要講的是研究者在海洋的最深處發(fā)現(xiàn)了生命(注意B選項只是其中的一個發(fā)現(xiàn),太片面),故本題答案為A選項.
點評 本文是一篇新聞報道類閱讀,題目涉及多道細節(jié)理解題,做題時結(jié)合原文和題目有針對 性找出相關(guān)語句進行仔細分析,結(jié)合選項選出正確答案.推理判斷也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確的答案.
