用作狀語的從句叫做狀語從句(adverbial clause)。引導狀語從句的關聯(lián)詞是某些從屬連詞。如：
(1)The sun was out again when I rode up to the farm. 當我騎馬到達農(nóng)場時，太陽又落山了。(關聯(lián)詞是從屬連詞when)
(2)He distrusted me because I was new. 他不信任我，因為我是新來的。(關聯(lián)詞是從屬連詞because)
(3)I met him as I was coming home. 在回家的時候，我遇見了他。(關聯(lián)詞是從屬連詞as)
(4)He orders me about as if I were his wife. 他指我干這干那，好像我是他妻子似的。(關聯(lián)詞是從屬連詞as if)
狀語從句同狀語一樣，在句中的位置比較靈活，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，我通常乘公共汽車上班。(從句置于句首)
(6)Stay where you are! 就地停著!(從句置于句末)
(7)I come here every month since I was a child to see my grandfather. 我從小就每月來看我的祖父。
