[教材P63] The world went into shock,most people having assumed that this space flight would be no more dangerous than travelling in an aeroplane.

(2)not+比较级+than含义是“不比……怎么样” 比如not better than...不比……好。

(3)比较级的其他特殊表示方法:

①表示两者之中“较……”,用the+比较级+of the two。

This method is superior to that one.

这种方法优于那种方法。

(4)形容词比较级可以被副词如a little(一点),much(得多),even(更加),still(更加),far(……得多)等修饰,但不可用very修饰。

五、长难句分析

Millions watched that first lunar landing on black and white television sets,their hearts in their mouths,aware of how arduous and hazardous an undertaking it was,and of the many things that could go wrong.

分析:本句的主干部分是Millions watched that first lunar landing on black and white television sets,本句中独立主格结构是their hearts in their mouths,aware of how arduous and hazardous an undertaking it was,and of the many things that could go wrong这部分也是作状语。and 是表示并列关系,而且后面省略了形容词aware。

译文:数以百万计的人在黑白电视机上观看了第一次登月,他们的心提到了嗓子眼,意识到这是一项多么艰巨和危险的任务,也意识到许多可能会出错的事情。怎么给孩子选择较好的冬令营?
