五、阅读理解
In December 2021, people in Shenzhen found that water ran more slowly from their taps. The government said the city was facing its most serious water shortage ever.
Some other cities in the southern part of China, are also becoming “pared with northern areas, southern areas have more rain and are close to more rivers and lakes. So why are they still short on water
In big cities like Shenzhen and Guangzhou, populations are growing fast. As a result, people and factories need more and more water. Each person in Shenzhen has less than 200 cubic meters of water each year. It’s 1/12 of the country’s average (平均水平). According to the UN, it is an “absolute （完全的）water shortage” when the number is below 500 cubic meters.
Weather change is making the water problem worse. For example, most cities in Guangdong depend on the Dongjiang River as their main source (来源) of water. In 2021, the river was reported to be drying up. Because of weather change, there’s also less snow in the mountains of Tibet. The snow has long been the source of water for many areas in China. Those mountains might provide less water in the future.
There are other reasons for water shortages. For example, water pollution makes it harder to get clean drinking water. Factories and farms don’t use water efficiently(有效地). Some cities have enough rainfall, but don’t have big lakes or reservoirs (水库) to store water. The water just goes into the sea.
March 22 is World Water Day. The theme this year is “groundwater ”. We can’t see groundwater. It’s under our feet. But it plays an important role in our lives. About 98 percent of Earth’s fresh water is groundwater. It is 60 times as plentiful (丰富的 ) as the fresh water in lakes and rivers. But in many places, people overuse and pollute groundwater. We should pay more attention to this hidden water resource.
根据短文内容选择最佳答案。
39．The underlined word “shortage” in the passage means ________.
A．短小 B．短缺 C．短暂
40．The amount of water each person has in Shenzhen each year ________.
A．meets the UN’s standards
B．is higher than the country’s average
C．shows that the city’s water problem is serious
41．What other reasons for water shortages mentioned in the fifth paragraph
①Water pollution ②Weather change ③Lack the storing place ④Populations
A．①③ B．②④ C．①④
42．Which of the following is TRUE according to the passage
A．About 60 percent of Earth’s fresh water is groundwater.
B．Water pollution makes it easier to get clean drinking water.
C．Mountains in Tibet have less snow.
43．The passage is mainly about ________.
A．water pollution B．water shortage C．World Water Day

41．细节理解题。根据“water pollution makes it harder to get clean drinking water”以及“Some cities have enough rainfall, but don’t have big lakes or reservoirs (水库) to store water”可知水污染使人们更难获得干净的饮用水，而且有些城市有足够的降雨量，但没有大湖或水库以储存水。故选A。
42．细节理解题。根据“there’s also less snow in the mountains of Tibet”可知西藏山区的雪变少了。故选C。
43．主旨大意题。通读全文可知，本文主要讲述了水资源的短缺以及原因。故选B。
六．例文：
To make our Hometown Better
Boys and girls，
I’m Li Hua. It’s my honor to share my opinions with you.
Now, thanks to the poverty eradication and the strategy of rural vitalization, great changes have taken place in our hometown. The roads are wider, and the houses they live in are bigger and brighter. People in poor areas move to the city and they become richer.
However, pollution is also becoming more and more serious. Some people throw litter around. Some people have cut down too many trees. The birds have gone. What should we do to make our hometown better
First, we must stop pouring dirty water into the rivers or lakes nearby. Second, whenever you visit a park , take away what you bring there—keep rubbish in a bag until you can put it in a dustbin. Third, we should plant more trees, flowers or grass. Fourth, it is necessary for us to use a glass cup instead of a paper cup because this saves paper. Let’s take actions together.
If everyone makes a contribution to protecting the environment, our hometown will be better and better.
That’s all. Thank you.
