用作状语的从句叫做状语从句(adverbial clause)。引导状语从句的关联词是某些从属连词。如：
(1)The sun was out again when I rode up to the farm. 当我骑马到达农场时，太阳又落山了。(关联词是从属连词when)
(2)He distrusted me because I was new. 他不信任我，因为我是新来的。(关联词是从属连词because)
(3)I met him as I was coming home. 在回家的时候，我遇见了他。(关联词是从属连词as)
(4)He orders me about as if I were his wife. 他指我干这干那，好像我是他妻子似的。(关联词是从属连词as if)
状语从句同状语一样，在句中的位置比较灵活，可置于句首、句末或句中。如：
(5)When it rains, I usually go to the office by bus. 逢下雨，我通常乘公共汽车上班。(从句置于句首)
(6)Stay where you are! 就地停着!(从句置于句末)
(7)I come here every month since I was a child to see my grandfather. 我从小就每月来看我的祖父。
