Question

这里的when引导的是时间状语从句还是条件状语从句?
Google Maps,for another,is one of the most popular web services on the planet,but it feels utilitarian and bland when compared to the more playful,personal,and mobile-optimised Foursquare.

Answer 1

when这里是用作连词时讲, 引导的时间状语从句
1.用作从属连词,意为“当……的时候[at the time when ]”,引导时间状语从句.例如：
①You are so beautiful whenyou smile.
②They learned a lot fromthe peasants when they stayed in the village.

【点津】如果 when 引导的从句中的主语和主句中的主语一致,且从句中的谓语动词是“ be ＋分词”或从句主语是 it ,则 be 动词及其主语常可省略.例如：
③When（ he was ）asked why he was late, he made no answer.
④I'll tell him about it when（ it is ）possible.
这就是为什么是when compared to 是因为它省略了when后面的 it is 还原后是
when it is compared to the more playful.
