1、Unit 2 My Favourite School Subject lesson 16 unit review語法專項講解語法專講現在完成時： 1.現在完成時的基本概念和用法： 現在完成時由have（has）動詞的過去分詞構成。規則動詞的過去分詞的構成與動詞過去式相同，不規則動詞的過去分詞各不相同，需個別記憶。 （1）現在完成時表示過去所發生的動作對現在的影響或產生的結果，常與just（剛剛），already（已經），ever（曾經），never（從來），yet（尚，還）等表示時間的副詞搭配使用。 Have you ever seen the film?  你看過這部電影嗎？ Sh

2、e has already bought a lot of things.  她已經買了許多東西。 （2）表示一個從過去某個時間開始，延續到現在并可能持續下去的動作，常與表示段時間的時間狀語連用，這樣的時間常用since或for來構成。since后面加時間點或從句（從句的時態常用一般過去時）for后加時間段： He has worked here for 15 years.  他在這里工作了15年了。 I have studied English since I came here.  自從我來這里，一直在學英語。 肯定式，否定式，疑問式如下： I （We, Yo

3、u, They）have read it.  He （She）has read it.  I （We, You, They）have not read it.  He （She）has not read it.  Have I （we, you, they）read it?  Has he （she）read it?  （3）某些非延續性動詞即動作開始便終止的動詞，在現在完成時中不能與表示一段時間的狀語搭配。例如下面這些動詞屬于非延續性動詞，并非不能用于現在完成時，而是不能接由for或since引導的時間狀語。die, arrive,

4、 join, leave, go, finish, buy, come lend, borrow, marry, 例如： He has come here for two hours. （×）他來了兩個小時了。 He has been here for two hours.  （4）have （has）gone to表示去了某地但還沒有回來。have（has）been to表示去過某地并且已經回來。 He has gone to Shanghai.  他到上海去了。 He has been to Shanghai.  他去過上海。 2. 現在完成時與一般

5、過去時的區別： 現在完成時表示過去發生的某一動作對現在造成的影響或結果，強調的是現在的情況，所以它不能和表示過去的時間狀語連用。而一般過去時只單純表示過去的動作或狀態，和目前情況無關，它可以和表示過去的時間狀語，如yesterday, last year, just now等連用。試比較： It snowed heavily yesterday.  昨天雪下得很大。 It has snowed for three days.  已經下了三天雪了?，F在完成時專項練習針對練習基礎過關 課堂鞏固，基礎闖關一、 單項選擇。()1、Both  his
