C
Research recently published in the journal *Science* studied land subsidence(地面沉降) in China's major cities,raising people's worries about land sinking in the country.
However,Hu,co-author of the study,said this idea isn't right scientifically. “Almost every city has areas of sinking and uplift(上升),” Hu told the *Intellectual*,a new science and technology media. The sinking of certain areas in a city does not mean the whole city is sinking. Human activities,like digging to build or taking out groundwater,are often the reason for it. What matters is how the areas are influenced and how quickly the land changes.
In fact,during times of fast economic development,the rate of land subsidence in China has been much slower compared to other countries.
For example,in San Jose,California,the USA,certain areas sank by 1.2 metres between 1912 and 1933. This was the time when the area quickly developed. The subsidence rate in Tokyo,Japan,even reached 27 centimetres a year during the 1950s. However,the subsidence rates in major Chinese cities are still around a few millimetres a year.
Even so,the government has taken measures to slow down the sinking. The key is not taking out too much water from the ground. The South-to-North Water Diversion Project(南水北调工程) is offering a helping hand to the country's northern cities. Through this project,less water from the ground is used in northern areas and land subsidence in many areas of Beijing and Tianjin has stopped.
Shanghai has also reduced yearly ground subsidence from around 10 mm in 1995 to 6 mm in 2019 through efforts such as improving the water supply system(供水系统) and closing deep wells(井),according to *The Paper*.
(D) 7. Hu might agree that ______.
A. nearly half of China's cities are sinking B. land subsidence is not a problem at all C. the sinking of certain areas matters most D. many cities have areas of sinking and uplift
(C) 8. What is the major cause of land subsidence in China according to the passage?
A. Water pollution. B. High buildings. C. The use of groundwater. D. The South-to-North Water Diversion Project.
(A) 9. What measure has Shanghai taken to stop land subsidence?
A. Using less groundwater. B. Using water from southern cities. C. Encouraging people to use more water. D. Using recycled water.
(D)10. What is the purpose of the passage?
A. To show the rate of land subsidence in China. B. To introduce the South-to-North Water Diversion Project. C. To explain the different causes of land subsidence. D. To discuss land subsidence and present solutions.

这是一道英语阅读理解题，主要考查学生对文章内容的理解和分析能力。题目给出了一个关于中国地面沉降的阅读材料，并附带了几个问题。学生需要通过阅读材料，理解文章的主旨和细节，然后根据文章的内容来回答这些问题。
对于第7题，需要找到Hu的观点，通过阅读材料可以发现，“Almost every city has areas of sinking and uplift(上升),”是Hu的观点，因此选项D是正确的。
对于第8题，需要找到中国地面沉降的主要原因，通过阅读材料可以发现，“Human activities,like digging to build or taking out groundwater,are often the reason for it.”这句话表明，人类活动，如挖掘建筑或抽取地下水，往往是地面沉降的原因。而在中国，抽取地下水是主要原因，因此选项C是正确的。
对于第9题，需要找到上海采取的阻止地面沉降的措施，通过阅读材料可以发现，“Shanghai has also reduced yearly ground subsidence from around 10 mm in 1995 to 6 mm in 2019 through efforts such as improving the water supply system(供水系统) and closing deep wells(井)”这句话表明，上海通过改进供水系统和关闭深井来减少地面沉降，这些措施的实质就是减少地下水的使用，因此选项A是正确的。
对于第10题，需要理解文章的主旨，通过阅读材料可以发现，文章主要讨论了中国的地面沉降问题，并介绍了相关的解决方案，因此选项D是正确的。
