Question

【題目】 Scientists have come up with a new way to measure ocean trash(垃圾) and the numbers are even worse than thought. In 2010, eight million tons of plastic trash ended up in the ocean from coastal countries far more than the trash floating on the surface of the ocean. That ' s bad news. The even worse news is that the tonnage may increase by as much as ten times in the next decade unless the world finds a better way to improve how trash is collected and managed.

The new study identifies the major sources of plastic trash and names the top 20 countries producing the greatest amount of ocean trash. The United States is 20th. The rest of the list includes l1 Asian countries, Turkey, five African countries, and Brazil.

The size of the difference is huge --- 20 to 2,000 times more than the amount of floating trash. To make the figure eight million tons understandable, Jenna Jambeck, who led the study, compares it to lining up five grocery bags of trash on every foot of coastline around the globe. "And by 2025, those five grocery bags of plastic are going to be ten bags," she says. That would be 155 million tons a year if present trash management practices remain the same."

Ocean plastic has turned up everywhere. It has been found in the deep sea and buried in Arctic ice with terrible consequences for some 700 species of wildlife in the ocean.

The study has also created a new mystery. Because what flows into the ocean is so large, scientists now have to figure out where else it collects and in what amounts. "But what we need to do now is close the gap." says Richard Thompson, a scientist from the U.K.

A.There is no way to get rid of it,.

B.Eight million tons of trash goes into the ocean.

C.A lot more trash may be put into the ocean in the future.

D.The way to measure ocean trash hasn 't been found.

【2】Jenna Jambeck explains the seriousness of ocean trash mainly by ______.

A.showing the causesB.describing a process

C.making comparisonsD.making a classification

【3】The underlined part “the gap” in the last paragraph refers to the difference between ______.

A.what is harmless and what is dangerous

B.what is on the surface and what is in the deep sea

C.what is found and what can be recycled

D.what is from America and what is from other countries

【4】Which of the following can best describe the author 's tone in writing the text?

A.Doubtful.B.Hopeless.C.Critical.D.Concerned.

Answer 1

【答案】

【1】C

【2】C

【3】B

【4】D

【解析】

這是一篇說(shuō)明文。文章介紹了科學(xué)家們想出了一種測(cè)量海洋垃圾的新方法，測(cè)試結(jié)果比想象的還要糟糕�？茖W(xué)家們通過(guò)研究發(fā)現(xiàn)了塑料垃圾的主要來(lái)源，并且科學(xué)家們現(xiàn)在必須弄清楚塑料垃圾還能從哪里收集，收集多少。

【1】細(xì)節(jié)理解題。根據(jù)第一段The even worse news is that the tonnage may increase by as much as ten times in the next decade unless the world finds a better way to improve how trash is collected and managed. 更糟糕的消息是，除非世界找到更好的方法來(lái)改善垃圾的收集和管理，否則在未來(lái)十年里，垃圾的噸數(shù)可能會(huì)增加十倍之多�？芍�最令人擔(dān)憂(yōu)的問(wèn)題是將來(lái)垃圾的數(shù)量還可能會(huì)增加。故選C項(xiàng)。

【2】推理判斷題。根據(jù)第三段To make the figure eight million tons understandable, Jenna Jambeck, who led the study, compares it to lining up five grocery bags of trash on every foot of coastline around the globe. 為了讓八百萬(wàn)噸這個(gè)數(shù)字更容易理解，這項(xiàng)研究的負(fù)責(zé)人Jenna Jambeck把它比作在全球每一英尺的海岸線(xiàn)上排列五個(gè)食品袋的垃圾�？芍�，Jenna Jambeck是通過(guò)作對(duì)比的方法來(lái)說(shuō)明垃圾數(shù)量的嚴(yán)重性。故選C項(xiàng)。

【3】詞義猜測(cè)題。根據(jù)最后一段Because what flows into the ocean is so large, scientists now have to figure out where else it collects and in what amounts. 因?yàn)榱魅牒Ｑ蟮乃�是如此之大，科學(xué)家們現(xiàn)在必須弄清楚它還能從哪里收集，收集多少�？芍�，這里“哪里”包括海洋表面和海底，所以“the gap”指的就是“海洋表面和海底”垃圾數(shù)量的差異。故選B項(xiàng)。

【4】推理判斷題�？疾樽髡叩膽B(tài)度，根據(jù)全文作者描述的數(shù)據(jù)以及尤其是兩位科學(xué)家說(shuō)的話(huà)，說(shuō)明了作者對(duì)于海洋垃圾增加還是非常關(guān)心的。故選D項(xiàng)。
