But during the past 10 years or so, there has been a large and rapid (快速的) drop in the world’s birth rate (比率). Families are smaller now than they were a few years ago. It is happening in both developing countries (such as China and India) and developed countries (such as America and England). Some families don’t want to have more babies because they believe that it’s difficult for them to raise two or more children. China is such a country that it has already cut its rate of population growth since 1970. Most Chinese families have no more than one child. And it reached a zero population growth rate in 2010. But in 2021, the Chinese government passed laws to encourage (鼓励) families to have three babies, because there are too many old people now. Some factories can’t find enough people to work. That’s terrible. Several countries in Europe already have a negative growth rate. Experts say that these countries could face a serious shortage (短缺) of workers in the future. And those who are working could face higher taxes (税) to help support the growing number of retirees (退休人员). 11．The world population can reach ________ in 2025.

But that’s just one example about numbers in China. When I first came here, I was surprised to see that many websites had numbers in their names instead of letters. I soon found that this is actually convenient, as Chinese characters (汉字) cannot be used for website addresses. 28 In pinyin, the telecom company China Unicom is called Zhongguo Liantong. If the company used their pinyin name for their website address, it would be quite long. 29 In addition, the pronunciations of some numbers sound similar to other words in Chinese. This is wordplay (双关语). For example, the numbers “520” in Chinese sound similar to the pronunciation of the Chinese phrase “I love you”. 30 A．They can only use numbers or letters instead. B．There are also superstitions (迷信) about some numbers in China. C．In western countries, some people think the number 13 brings bad luck. D．It is interesting to see how Chinese people use numbers in different ways. E．So instead, they used the hotline number—10010.com. This is easier to type and remember. F．Many couples choose to get married on May 20th for this reason. 第三节 你有在外租房的经验吗？以下右栏是出租房的广告信息，请根据左栏五位租客的租房要求配对。从A—E中选出对应的答案填入空白处。（共5小题，每小题1.5分） 31 Jackson has just graduated from a university and he wants to rent a small and cheap house. 32 Mr and Mrs. Robinson want to live in a town with their four children.
