今天為大家推送的是四六級，一起來(lái)看看吧！英語(yǔ)四六級語(yǔ)法（46）比較過(guò)去時(shí)與現在完成時(shí) 1)過(guò)去時(shí)表示過(guò)去某時(shí)發(fā)生的動(dòng)作或單純敘述過(guò)去的事情，強調動(dòng)作;現在完成時(shí)為過(guò)去發(fā)生的，強調過(guò)去的事情對現在的影響，強調的是影響。 2)過(guò)去時(shí)常與具體的時(shí)間狀語(yǔ)連用，而現在完成時(shí)通常與模糊的時(shí)間狀語(yǔ)連用，或無(wú)時(shí)間狀語(yǔ)。 一般過(guò)去時(shí)的時(shí)間狀語(yǔ): yesterday, last week，…ago, in1980, in October, just now, 具體的時(shí)間狀語(yǔ) 共同的時(shí)間狀語(yǔ): this morning, tonight,this April, now, once，before, already, recently，lately 現在完成時(shí)的時(shí)間狀語(yǔ) for, since, so far, ever, never, just, yet,till / until, up to now, in past years, always, 不確定的時(shí)間狀語(yǔ) 3)現在完成時(shí)可表示持續到現在的動(dòng)作或狀態(tài)，動(dòng)詞一般是延續性的，如live, teach, learn, work, study, know. 過(guò)去時(shí)常用的非持續性動(dòng)詞有come, go, leave, start, die, finish, become, get married等。 舉例： I saw this film yesterday. 全部倒裝 全部倒裝是只將句子中的謂語(yǔ)動(dòng)詞全部置于主語(yǔ)之前。此結構通常只用與一般現在時(shí)和一般過(guò)去時(shí)。常見(jiàn)的結構有： 1) here, there, now, then, thus等副詞置于句首, 謂語(yǔ)動(dòng)詞常用be, come, go, lie, run。 There goes the bell. Then came the chairman. Here is your letter. 2) 表示運動(dòng)方向的副詞或地點(diǎn)狀語(yǔ)置于句首，謂語(yǔ)表示運動(dòng)的動(dòng)詞。 Out rushed a missile from under the bomber. Ahead sat an old woman. 注意：上述全部倒裝的句型結構的主語(yǔ)必須是名詞，如果主語(yǔ)是人稱(chēng)代詞則不能完全倒裝。 Here he comes.Away they went. (強調看的動(dòng)作發(fā)生過(guò)了。) I have seen this film. (強調對現在的影響，電影的內容已經(jīng)知道了。) Why did you get up so early? (強調起床的動(dòng)作已發(fā)生過(guò)了。) Who hasn't handed in his paper? (強調有卷子，可能為不公平競爭。) She has returned from Paris. 她已從巴黎回來(lái)了。 She returned yesterday. 她是昨天回來(lái)了。 He has been in the League for three years. (在團內的狀態(tài)可延續) He has been a League member for three years.
