where : 当先行名词在从句中当地点状语时,用关系副词where连接 例如: The crime rate rises in cities where the unemployment rate increases. 句中的where = in cities, 表示行为发生的地点。 这里的要点是能否区分是用that 还是用 where, 即:是做主语、宾表语,还是做地点状语,例如: I love the small town that we visited last week. 句中town做动词visited的宾语,即参观过的小镇,故用that连接。 I love the small town where I lived during my childhood. 句中town 是动词lived的地点,即童年时住过的小镇,故用where. 这也是定语从句的一个考点。 when : 当先行名词在从句中当时间状语时,用关系副词when连接, 例如: July is the month when we have a lot of rain. 注意when定语从句后推的现象,例如: I think the day will finally come when air pollution can be put under control. 放在主句后面作非限制定语从句时,when一般译为此时,那时, 例如: The meeting will be put off until next month, when we will have made all the preparations. 另一个关系副词是why,由于它固定与the reason搭配, 即: the reason why,不难理解,一般也不作为考试的重点。例如: |
