Let's begin!Example 1:The population of a city increased by 10% last year. If the initial population was 500,000, what is thenumberof people living in the city now?To solve this problem, we can apply the formula:thenumberof = initial population × (1 + percentage increase/100)Using the given information, we can calculate:thenumberof = 500,000 × (1 + 10/100)= 500,000 × 1.1= 550,000Therefore, the number of people living in the city now is 550,000.Example 2:A company experienced a 20% decrease in sales last month. If the total sales for the month were $500,000, what is thenumberof the company's sales after the decrease?To find the answer, we can utilize the formula:thenumberof = initial sales × (1 - percentage decrease/100)Applying the given information:thenumberof = $500,000 × (1 - 20/100)= $500,000 × 0.8= $400,000Hence, the company's sales after the decrease amount to $400,000.Example 3:A study revealed that the number of smartphones sold worldwide increased by 15% in the last quarter. If thenumberof smartphones sold in the previous quarter was 100 million, what is the estimated number of smartphones sold in the current quarter?Using the formula:thenumberof = initial count × (1 + percentage increase/100)We can calculate:thenumberof = 100,000,000 × (1 + 15/100)= 100,000,000 × 1.15= 115,000,000Therefore, the estimated number of smartphones sold in the current quarter is 115 million.Example 4:In a survey, it was found that thenumberof children who own a pet in a particular neighborhood decreased by 25% compared to last year. If the previous number of children with pets was 200, how many children own a pet now?Applying the formula:thenumberof = initial count × (1 - percentage decrease/100)We can calculate:thenumberof = 200 × (1 - 25/100)= 200 × 0.75= 150Hence, the number of children who own a pet now is 150.These examples demonstrate the correct use of "thenumberof" in various scenarios. Whether it is calculating changes in population, sales figures, or survey results, understanding how to apply this phrase accurately is essential for clear communication and effective analysis.In conclusion, the proper usage of "thenumberof" involves employing it in the context of calculations and quantifying changes.

九年级英语数量表达法练习30题含答案解析1. There ____ a large number of students in our school.A. isB. areC. hasD. have答案：B。

解析：“a large number of”表示许多，修饰可数名词复数，作主语时，谓语动词用复数形式。

A选项“is”是单数形式，不符合；C和D选项“has”和“have”表示拥有，这里是存在有，不是所属关系，所以不能用。

2. The number of the books in the library ____ over ten thousand.A. isB. areC. beD. were答案：A。

解析：“the number of”表示的数量，作主语时，谓语动词用单数形式。

B选项“are”是复数形式，不符合；C选项“be”是原形，不能直接作谓语；D选项“were”是过去式复数形式，也不符合。

3. A number of teachers ____ to the meeting yesterday.A. was invitedB. were invitedC. is invitedD. are invited答案：B。

解析：“a number of”修饰可数名词复数，这里指许多老师，且句中有“yesterday”表示过去的时间，所以要用一般过去时的被动语态，主语是复数，谓语动词用“were invited”。

A选项“was invited”是单数形式，不符合；C选项“is invited”是一般现在时的单数形式，不符合；D选项“are invited”是一般现在时的复数形式，不符合时态要求。
