如:It takes less time to go there by air than by train.

$ q) U6 `* P/ F: K! b6 t. h 2.为避免重复,than之后的从句中有些成分可以省略,只把相比的部分突出出来: 0 _1 r9 ^; t6 L% u, w9 M! g
情况1: 用指示代词that, those来代替省略的部分,
1 y/ b/ q9 v3 B5 }" { 如:The population of China is much larger than that of Great Britain. 5 e1 Q. y9 O) r4 f$ O( r
(that 指代the population)
2 s: U4 Z5 q7 I- { His designs won more acclaim than those of his fellow colleagues. - R$ }" T. p7 @9 p9 k
(those 指代 designs) - {* K L- P) `
情况2: 在省略的过程中,若than之后从句的谓语部分相同, 比较的是主语部分, 那么谓语部分通常用助动词do来代替, 并且习惯上将从句主语和助动词倒装 (do + 主语)

6 k# h- u& |2 U) Y+ N 解释:空格前出现了形容词比较级,空格后是比较对象,应由than连接,选项中只有A符合条件,其中由助动词do引起了一个小倒装 |
