引導(dǎo)的時間狀語從句

When和While的區(qū)別

①when是atorduringthetimethat,既指時間點，也可指一段時間，while是duringthetimethat，只指一段時間，因此when引導(dǎo)的時間狀語從句中的動詞可以是終止性動詞，也可以是延續(xù)性動詞，而while從句中的動詞必須是延續(xù)性動詞。

②when說明從句的動作和主句的動作可以是同時，也可以是先后發(fā)生；while則強調(diào)主句的動作在從句動作的發(fā)生的過程中或主從句兩個動作同時發(fā)生。

③由when引導(dǎo)的時間狀語從句，主句用過去進行時，從句應(yīng)用一般過去時；如果從句和主句的動作同時發(fā)生，兩句都用過去進行時的時候，多用while引導(dǎo)，如：

a.Whentheteachercamein,weweretalking.當此句改變主從句的位置時，則為：

Whileweweretalking,theteachercamein.

b.Theyweresingingwhileweweredancing.

④when和while還可作并列連詞。when表示“在那時”；while表示“而，卻”，表對照關(guān)系。如：

a.Thechildrenwererunningtomovethebagofricewhentheyheardthesoundofamotorbike.

孩子們正要跑過去搬開那袋米，這時他們聽到了摩托車的聲音。b.Heisstrongwhilehisbrotherisweak.

現(xiàn)在完成時用法：構(gòu)成：標志詞：1.表示動作發(fā)生在過去某一時刻并已經(jīng)結(jié)束，但該動作對現(xiàn)在產(chǎn)生了影響2.表示動作開始于過去某一時刻并一直延續(xù)到現(xiàn)在或可能仍要繼續(xù)下去have/has+過去分詞already,ever,just,never,yet,before,recently,for…,since…試試你能行！1.I
