(2)30÷15×52=7 800(个).答:估计“市民热线”今年(按52周计算)将接到的热线电话有7 800个. 四、18.解:(1)223+2172=220(棵).答:这批工人前两天平均每天种植220棵景观树木. (2)该园林公司需要增派工人.理由:这批工人3月1日到5日平均每天的植树量为223+217+198+195+2025=207(棵).估计到3月10日,这批工人可种植景观树木207×10=2 070(棵).因为2 070<2 200,所以该园林公司需要增派工人.19.解:(1)2 100÷70%=3 000(辆).答:该季度的汽车产量是3 000辆.(2)圆圆的说法不对,因为不知道第二、第三这两个季度的汽车销售数量,所以无法比较这两个季度的汽车产量.五、20.解:(1)200;80 补全频数分布直方图如图.(2)90°(3)2 000×(40%+12%)=1 040(人).答:估计该校学生中阅读能力优秀的有1 040人.21.解:(1)200(2)20;25(3)平均每天帮助父母干家务所用时长为20~30分钟的学生人数为200×20%=40.补全频数分布直方图如图:(4)平均每天帮助父母干家务所用时长不少于30分钟的学生占比为25%+5%=30%,2 000×30%=600(人).答:平均每天帮助父母干家务所用时长不少于30分钟的学生有600人.。

It covered many cities with thick clouds of yellow dust ( 尘土).The storm came from Mongolia. It was the largest sandstorm in China in the past 10 years. Many flights and classes were canceled because the visibility ( 能见度) was lower than 500 meters.The storm was the result of warm and dry weather in the area, together with the strong winds from Mongolia. “There has been little rainfall so far this spring and the temperature is rising. So now it is a worrying time for sandstorms,”said an expert from Beijing.In recent years, sandstorms haven’t been as common in northern China as before. The land with desertification (沙漠化) has been falling by 7, 585 km2per year in China, and the area of sandy land has been decreasing by 1, 284 km2 a year. This is thanks to China’s Three-North Shelter Forest Program (TNSFP 三北防护林工程) which started in the 1970s. Millions of trees have been planted in northern China to prevent sandstorms and protect the environment.Besides, China has a color-graded weather warning system ( 预警系统) for sandstorms, with red meaning the most serious, followed by orange and yellow. Therefore, people would have time to get prepared for the sandstorm.Sandstorm <1 kilometerSevere sandstorm <500 metersSuper severe sandstorm <50 meters26. What caused the sandstorm from Mongolia?A. Cold and wet weather together with the strong winds.B. Warm and dry weather together with the strong winds.C. Warm and wet weather together with the strong winds.D. Warm and wet weather together with the heavy rain.27. The underlined word “decreasing” means“________”.A. going upB. putting downC. going downD. putting up28. When did TNSFP start?A. In the 1970s.B. In the 1980s.C. In the 1940s.D. In the 1990s.29. If the visibility in your city is 700 meters, what color will the warning be?A. Red.B. Orange.C. Blue.D. Yellow.30. What can we infer (推断) from the passage?A. We have taken some actions to prevent sandstorms.B. Sandstorms have never changed.C. The weather is getting worse and worse.D. The weather is getting colder and colder.四、词汇运用(每小题1. 5 分, 共15 分)A)用括号内所给词的适当形式填空。
