句型解析
1【教材原句】 The world’s population has grown to more than six times what it was in 1800.(P22)
世界人口已经增长到了1800年时的六倍多。

【句法分析】more than six times what it was in 1800是“倍数＋what从句”的形式，意为“是(比)……的……倍”。

倍数的表达方式有：
(1)A＋倍数＋形容词或副词的比较级＋than＋B，表示“A比B大(长、高、宽等)多少倍”。

(2)A＋倍数＋as＋形容词或副词的原级＋as＋B，表示“A是B的多少倍”。

(3)A＋倍数＋the size/height/length/width，etc.＋of＋B，表示“A是B的多少倍”。

(4)A＋倍数＋what从句，表示“A是……的多少倍”。

完成句子
(1)这辆小车的速度比那辆卡车快两倍。

The car runs twice faster than that truck.
(2)亚洲的面积是欧洲的四倍。

Asia is 4 times as large as Europe.
(3)这座山的高度是那座小山的四倍。

This hill is 4 times the height of that small one.
(4)这条路是四年前的三倍长。

2【教材原句】People should take responsibility for not buying certain kinds of fish，because there_are not many left in the ocean.(P25)
人们应该为买不到某种鱼负责任，因为在海洋里已剩下不多的鱼了。

【句法分析】本句为because引导的原因状语从句，从句又为there be结构，其中left in the ocean为过去分词短语，作定语。

there be结构：
There is no time left；let’s hurry up!
时间不多了，我们快点吧！

【温馨提示】
(1)there be句型中，谓语动词除用be之外，还可用某些状态动词，如：remain，lie，exist，li ve以及表示位置转移的动词arrive，come，enter，follow，rise等。

(2)there be句型的非限定形式有there to be和there being两种形式，它们可以在句中作主语、宾语、状语等。

(3)there be中be的单复数取决于be后的名词，若有几个并列名词，则取决于第一个。

(4)There be＋n.＋v.ing/v.ed/to do中，若名词与后面的动词存在主动关系，用v.
ing形式；若表被动关系，则用v.ed；不定式既可以用主动形式又可以用被动形式。
