用法辨析

conj. (連詞)

• after可用作連詞連接一個(gè)時(shí)間狀語(yǔ)從句,從句中一般用現(xiàn)在時(shí)表示將來(lái)。

adv. (副詞)

• after用作副詞時(shí)常與soon, ever搭配,通常用于表示時(shí)間的名詞后。
• after用作副詞時(shí)不用于比較等級(jí)。
• 注意after和in的使用：從某時(shí)說(shuō)到多少時(shí)間以后，不用after，而用in。如果指“某個(gè)時(shí)刻，日期或事件以后”，用after。He will/would arrive in four weeks.He will(或would)arrive after four o'clock /5 July/the ceremony.
• 表達(dá)“某事件的若干時(shí)間以后”時(shí)，應(yīng)是“若干時(shí)間after事件”，而不是“after若干時(shí)間of事件”。可說(shuō)two hours after his arrival，不可說(shuō)after two hours of his arrival。在“two hours after his arrival”前加不同的介詞，有不同的意思:“two hours after his arrival”單用時(shí)指“他到達(dá)兩小時(shí)以后”。若前面加the，如the two hours after his arrival指“他到達(dá)以后的兩小時(shí)”，加for指“在他到達(dá)以后的兩小時(shí)全段時(shí)間里”，加in 跟沒(méi)有in意思相同，加within指“在他到達(dá)以后的兩小時(shí)中的某時(shí)刻”；
• 指“若干時(shí)間after日期或月份”時(shí)，常把當(dāng)天的日期或當(dāng)月除外。如five days after 3 July，指從7月4日算起的5天以后，也就是7月9日。但有例外，five days after I July可能指7月8日，months after July可能指11月，注意避免這種結(jié)構(gòu)產(chǎn)生誤解；
• 指“從過(guò)去的某時(shí)或某事說(shuō)到現(xiàn)在”時(shí)，不用after，用since，所以可說(shuō)Since his graduation he has been abroad.（since不可改成after）一定要改的話，可表示為After his graduation he went abroad. 這里的after是介詞，用作連接詞時(shí)用法一樣。He went abroad after he graduated. 不可說(shuō) He has been abroad after he graduated.
• half after four，five minutes after eight等是美國(guó)英語(yǔ)，相當(dāng)于英國(guó)英語(yǔ)half past four，five minutes past eight等，英國(guó)方言中也有half after four等表達(dá)方式；
• after引導(dǎo)的狀語(yǔ)從句，用現(xiàn)在時(shí)態(tài)，不用將來(lái)時(shí)態(tài)。I shall start after he comes.
