八年级英语下册《Unit 7》练习题及答案(人教版)
八年级英语下册《Unit 7》练习题及答案（人教版）Unit 7 What’s the highest mountain in the world?（知识讲解）deep的用法【知识详解】population的用法【知识详解】population意为“人口，人口数量”，作主语时，谓语动词用单数。
(1)前面有分数、百分数修饰population作主语时，谓语动词常用复数形式。
(2)形容人口的多少用large/big和small。
（3）询问某国、某地有多少人口的句型：What is the population of…?(4)表示“某地有多少人口”用“…has a population of…”或“The population of…is…”。
【例句】The world's population is increasing faster and faster.全世界的人口增长得越来越快。
【经典练】—Which country has the ________ population in the world?—China. It’s a little ________ than that of India.A．most; most B．biggest; bigger C．more; most D．bigger; biggest【答案】B【详解】句意：——世界上人口最多的是哪个国家？——中国。
它比印度的人口多一点。
考查比较级和最高级。
根据答语“China”及常识可知，上句应是问世界上人口最多的是哪个国家，应用最高级形式，先排除C/D选项；修饰人口的数量大，人口多用big或large。
结合选项，所以此处用big的最高级biggest；根据关键词than，可知第二空应该用比较级，此句是中国和印度的人口作比较，应是指中国的人口比印度要多一点，a little修饰比较级，用big的比较级bigger。
故选B。

fell free是英语口语中一个常用表达。
若有人让你feel free to do something, 就是让你无需拘束，只管按照自己的意愿去做某事。
e.g. A: Can I use your bathroom? 我可以用一下你的卫生间吗？B: Yes, feel free. 可以，请随意。
2. As far as I know, there are no other man-made objects as big as this.据我所知，再没有像它这样大的人造物体了。
1) as far as I know是一个固定的表达方式，还可以说so far as I know, 意思是“据我所知”。
e.g. As far as I know, Jack’s got twin sisters.就我所知，杰克有一对孪生姐妹。
They’re not coming today, so far as I know.他们今天不来了–就我所知是这样的。
2) 句中man-made是一个合成形容词，意为“人造的”。
像这样与-made复合而成的形容词不止一个。
常见的有：handmade (手工制作的)、homemade(家庭制作的)、machine-made(机制的)、tailor-made(量体定制的；特制的；定做的)，用以描述产品的生产或制造手段，特点等，甚至还有像self-made (自学而成的；自我奋斗而成的；天然形成的)可以用来描述人。
