SBⅠUnits 7-8 重点句型 1.Where there is a river, there is a city. (SBⅠ U7) 凡有河流的地方必有城市。 where是连接副词，引导状语从句，意为“在/到……地方”，相当于介词in/at/to + the place + where从句（定语从句）。 where引导状语从句和定语从句的区别： ①where引导状语从句时，它的前面没有先行词，不能用“介词+which”替代。有时含有条件意味。 ②where引导定语从句时它的前面有先行词，可用“介词+which”替代。 ①Crops grow well __________________(在有……的地方) plenty of sunshine. ②You should put the book__________________ (回原处)． ③— Mom, what did your doctor say? — He advised me to live ______ the air is fresher. A. in where B. in which C. the place where D. where 【答案】 ①where there is ②where it was ③D where引导的是地点状语从句，表示“住在空气更新鲜的地方”。选项C如果是in the place where也是正确的。“介词+which”不能替代引导状语从句的where，故不可选B项。 2. It is said to be the city’s largest ever cultural relics repair project. （SBⅠ U7） |
