Question

【題目】As sea levels climb, even Washington, D. C. could see more frequent and widespread flooding at high tide.

Strong storms and high winds sometimes bring floods to coastal areas. But cities and towns along the US East Coast are flooding even in calm and sunny weather. Among them is Maryland’s capital Annapolis. Tourists there must sometimes walk through water flooding downtown streets surrounding the habor. Sometimes water covers roads in Atlantic City, N. J. Even the yards and basements of coastal homes near New York City sometimes flood.

All are suffering from this trend—normal high tides surpass (超過) a rising sea level.

Sea levels have climbed, on average, about 20 centimeters (8 inches) over the past 135 years. And a sharp increase in tide flooding is one of the more visible impacts affecting many coastal areas, notes William Sweet, an oceanographer.

Sweet and his co-workers recently analyzed data from 45 tide gauges (計量表) along the US coasts. These tools record the changing heights of tides as they rise and fall. From these data, Sweet’s team calculated the number of : “troublesome floods” in various coastal cities. These floods, Sweet explains, typically occur when water level is about 30 centimeters (1foot) above the historic level of the highest tides. In June 2014, the team reported finding a growing rise in these flooding events.

In Charleston, S.C. from 1957 to 1963, the city experienced troublesome floods an average of 4. 6 days per year. Bur from 2007 to 2013, the occurring rate of troublesome floods jumped five times. Annapolis city was even more serious. From1957 to 1963，troublesome floods were roughly 3. 8 days per year. From 2007 to 2013, the average was 10 times higher- 39. 3days a year.

“Over the next few decades, climate change probably drives sea levels even higher,” Sweet says. “So today’s flooding problems promise to become only more widespread and frequent.”

【1】What is Paragraph 2 mainly developed by?

A. Making comparisons.

B. Analyzing causes.

【2】Why are more flooding problems caused?

A. Because the river levels have been climbing.

B. Because climate has changed over the years,

C. Because the weather conditions are not stable.

A. There has been a growing rise in these analyzed flooding events.

B. The changes of heights of tides are usually in a small range.

C. The floods in coastal cities often occur when water level is above1foot.

D. The number of troublesome floods gradually gets less.

【4】What is the text mainly about?

【解析】 健康環(huán)保類閱讀。作者通過這篇文章向我們說明了隨著海平面上升，洪水發(fā)生的更頻繁，更廣泛，并列舉了洪水帶來的災難。科學家們對洪水問題的研究，說明了氣候變化對洪水的影響．

【1】C

細節(jié)理解題，根據(jù)第二段“Tourists there must sometimes walk through water flooding downtown streets surrounding the habor．Sometimes water covers roads in Atlantic City，N．J．Even the yards and basements of coastal homes near New York City sometimes flood”可知本段是通過舉例子來說明強風暴所帶來的影響，故選C

【2】B

細節(jié)理解題，根據(jù)最后一段“Over the next few decades，climate change probably drives sea levels even higher，"Sweet says．"So today's flooding problems promise to become only more widespread and frequent．"”可知近年來洪水對我們造成了很多問題是因為氣候變化，故選B

【3】A

推理判斷題，根據(jù)第五段Bur from 2007to 2013，the occurring rate of troublesome floods jumped five times．Annapolis city was even more serious．From 1957to 1963，troublesome floods were roughly 3.8days per year．From 2007to 2013，the average was 10times higher---39.3days a year．可知本段是通過列舉一些數(shù)據(jù)向我們分析了洪水發(fā)生的事件在不斷增加，故選A．

【4】B

主旨大意題。，前四段主要描述了隨著海平面的上上升，洪水發(fā)生的更頻繁，同時也給洪沿海地共造成了災難。針對此，許多科學家對洪水問題進行研究。分析全文可知，本文是關于洪水的研究，故選B．
