n. 人口；人口数量考向一 问人口数量的句型是：What’s the population of...?

How many people are there in Canada?
加拿大有多少人？ 形容人口多少用big，large或small。

谓语动词用单数，当其前有分数或百分数修饰时，
谓语动词可用单数或复数。
eg：The population of Nigeria is more than 100
million.(强调整体性)尼日利亚的人口数量

三的人口来自全国其他地方。【难点】典例The population of the world ________ still ________ now.(兰州)

A．long B．longer
C．Longest D．the longestD【点拨】本题用寻找题眼法。句意：众所周知，长江是世界上

容词最高级＋可数名词复数”结构。2dRole-play the conversation.Guide: Feel free to ? ask me anything on today's Great
Wall tour.
Tourist 1: How long is the wall?

about the parts from the Ming Dynasty, it’s about 8，

emperors build the wall?Guide: The main reason was to protect ? their part of

长”。how big 多大； how far 多远； how high 多高； how long 多长，故选D。
2．C 点拨：本题用固定短语法。“one of＋最高级＋名词复数”表示“最……之一”，排除A项；又根据地理知识可知，加拿大是北美洲的一个国家，它不在亚洲之内，所以要用“any＋单数名词”。故选C。
3．C 点拨：句意为“架子上有很多书，包括三本莫言的书。”include是动词原形，句中there be 句型不缺谓语动词； to include 表将来，或表目的，不符合题意；included 表被动，不符合题意，故选C。
4．A 点拨：protect...from...意为“保护……免受……”。
5．A 点拨：句意为“即使他再问我，我也不会帮助他。”even though引导让步状语从句，意为“即使”。
6．B 点拨：修饰动词短语arrived at the top of the mountain要用副词，所以选B。
7．C 点拨：long长的；high高的；thick厚的；wide宽的。句意：这湖里的冰大约有一米厚，在上面滑冰很安全。故选C。
8．C 点拨：本题用词义辨析法。discover发现；find找到；achieve成就，实现；stop停止。句意：梦想是美丽的。然而，实现梦想需要很多的时间和劳动。故选C。
9．B 点拨：提问人口时，population要与what连用；形容人口多或少用large/big/small，故选B。
10．D 点拨：本题用短语辨析法。take out取出；take off起飞；take away拿走；take in吸入。句意：在珠穆朗玛峰峰顶很难吸入空气。故选D。
