狀語可以由副詞, 副詞，介詞短語，不定式和從句等來擔任。狀語一般放在被修飾的詞之後或放在句尾。副詞作狀語時可放在被修飾的詞前或句首。　　We went to the countryside last year.　　I often read the news paper at night.　　狀語在句子中的位置很靈活，常見情況為：通常在句子基本結構之後，強調時放在句首；修飾形容詞或副詞時，通常位於被修飾的詞之前；表示時間、地點、目的的狀語一般位於句子兩頭，強調時放在句首，地點狀語一般須在時間狀語之前；一些表示不確定時間（如：often）或程度（如：almost）的副詞狀語通常位於be動詞、助動詞、情態動詞之後，動詞之前。　　有時狀語在句中的某個位置會引起歧義，應注意，如：The boy calls the girl in the classroom.一般理解成‘男孩喊教室裡的女孩‘（此時in the classroom為girl的定語），也可以理解為‘男孩在教室裡喊女孩’（此時in the classroom為地點狀語），最好寫作‘In the classroom, the boy calls the girl.'　　副詞（短語）作狀語：　　The boy needs a pen very much（程度狀語）　　The boy needs very much the pen bought by his mother.（賓語較長則狀語前置）The boy really needs a pen.（程度狀語）　　The boy needs a pen now./Now, the boy needs a pen./The boy, now, needs a pen./男孩現在需要一支鋼筆。（時間狀語）　　介詞短語作狀語：　　In the classroom, the boy needs a pen.（地點狀語）　　Before his mother, Tom is always a boy.（條件狀語)　　On Sundays, there is no student in the classroom.（時間狀語)　　分詞（短語）作狀語：　　He sits there, asking for a pen./ （表示伴隨狀態）　　Having to finish his homework, the boy needs a pen./（原因狀語）　　Frightened, he sits there soundlessly./ （原因狀語）　　不定式作狀語：　　The boy needs a pen to do his homework.（目的狀語）　　To make his dream come true, Tom becomes very interested in business./　　名詞作狀語：　　Come this way!/ （方向狀語）　　狀語從句：時間狀語從句/地點狀語從句/原因狀語從句/結果狀語從句/目的狀語從句/比較狀語從句/讓步狀語從句/條件狀語從句
