Question

    Something strange was happening inside Anne' s home. During the summer of 2014, twins Gavin and Garrett, then three, each had skin rash (疹子) that wouldn't go away. 14-year-old J. D. had stomach pains so severe that he couldn’t climb the stairs，but tests found nothing wrong. By winter, the family's health problems were getting worse.

One day, Anne found brown water flowed out of the tap. Worried that the water was polluted, the family began using bottled water for cooking，drinking, and bathing.

In January 2015，the city of Flint sent out a notice stating that the water supply—which had been switched, in a cost-cutting measure, from the Detroit water system to the Flint River the previous spring—contained high levels of trihalomethanes (三卤甲烷). The notice warned that elderly people might be at risk for health problems but emphasized that the water was otherwise safe to drink.

Shocked, the self-claimed "stay-at-home mom turned water warrior" researched the water supply and searched the Internet for information that she distributed to city officials, listing the side effects of exposure to trihalomethanes. Then she urged her neighbors to attend city council meetings, where they shared their health problems. Still, officials insisted the water was safe to drink. So Anne demanded that the city test her water. The results were disturbing. The trihalomethanes were the least of her problems. The tests included that the lead levels in her water were nearly seven times the legal amount.

Anne had her children tested for lead. All the kids showed lead poisoning. She requested Flint's water quality reports and discovered that the city wasn't applying the proper corrosion (腐蚀) control standards to its pipes; the standards prevent the metal in pipes from leaking into the water.

1.How did Gavin suffer from the disease?

A.His stomach hurt so much that he couldn’t' climb the stairs.

B.He had rash on his skin which wouldn’t' disappear.

C.His disease got too ill for him to get any medical tests.

D.He had weak eyesight and couldn't go to school,

2.Why did the city of Flint change its water supply?

A.The Detroit water system had been polluted.

B.The Flint River was made clean a year ago.

C.They wanted to cut the cost of water supply.

D.The Flint River always has brown water.

3.The test of the water from Anne' s home showed that         .

A.her family had the worst of the trihalomethanes pollution

B.the water from her tap was safe to use except for drinking

C.her family was located in the most polluted part of the city

D.there was something more serious than the trihalomethanes

4.The water problem was caused by        

A.the lack of proper corrosion control to the pipes

B.the overuse of water-purifying chemicals

C.the exposure to trihalomethanes in the water

D.the improper use of metal in the pipes

2.C

3.D

4.A

【解析】

本文是一篇记叙文，讲述了安妮的三个孩子因家里的饮用水中毒而生病，取证后她发现这是由供水管道缺乏适当的腐蚀控制引起的。

1.

细节理解题。根据第一段中的“During the summer of 2014, twins Gavin and Garrett, then three, each had skin rash (疹子) that wouldn't go away.”可知，2014年夏天，当时三岁的双胞胎加文和加勒特身上起了皮疹，而且它们还不消失，故B项正确。

2.

细节理解题。根据第三段中的“the water supply—which had been switched, in a cost-cutting measure, from the Detroit water system to the Flint River the previous spring”可知，为了削减供水成本，弗林特市从底特律供水系统改为弗林特河供水，故C项正确。

3.

细节理解题。根据第四段中的“The results were disturbing. The trihalomethanes were the least of her problems. The tests included that the lead levels in her water were nearly seven times the legal amount.”可知，水质检测结果令人不安，三卤甲烷是最小的问题，检测结果显示，安妮家水中的铅含量几乎是法定含量的7倍，也就是说安妮家的水中有比三卤甲烷危害性更大的有害物质，故D项正确。

4.

细节理解题。根据最后一段中的“She requested Flint's water quality reports and discovered that the city wasn't applying the proper corrosion (腐蚀) control standards to its pipes; the standards prevent the metal in pipes from leaking into the water.”可知，安妮要求弗林特市提供水质报告，发现该市没有对供水管道实施适当的腐蚀控制，从而使供水管道中的金属泄漏到水中（水质问题是由供水管道缺乏适当的腐蚀控制引起的），故A项正确。
