牢記詞匯。學(xué)習(xí)一門外語，詞匯是基礎(chǔ)也是開始。掌握語法。語法是將詞匯組織成句子的規(guī)則，學(xué)會了單詞如果語法掌握不好，那么就無從談句子和文章了。背課文，背誦一定數(shù)量的范文除了有利于學(xué)生閱讀理解的提高，還對學(xué)生英語寫作的提高很有幫助。

虛擬語氣

虛擬語氣也是一個難點(diǎn)。所謂虛擬語氣是表示說話人的愿望、假設(shè)、猜測或建議，而不表示客觀存在的事實(shí)。它通過句子的謂語動詞的特殊形式來表示。

現(xiàn)歸納如下：純假設(shè)，用虛擬，動詞時態(tài)退一級：條件句，分主從，主句謂語前加would

(should,could，might);表愿望,用虛擬，wish后面接賓語(從句)：現(xiàn)在過去與將來，動詞時態(tài)退一級：提建議，用虛擬，賓語(從句)動詞用(should)do：倆建議，三要求，再加堅(jiān)持與命令

(suggest,advise,demand,require,request,insist,order)：It is time和eoukd

rather,后接叢句用虛擬：部分主語從句中， 謂語用虛擬結(jié)構(gòu) (It is necessry

/important/natural/natural/strange/strange thatshould do)。 下面舉例說明：

A、If you came tomorrow,we would have the metting. (條件句虛擬)

B、Without air,there would be no living things.(同上)

C、We wish we had arrived there two hours earlier.(表示愿望虛擬)

D、He demanded that we (should)start right away.(表示建議虛擬)

E、It is(high)time that we left (should leave)now.(特殊從句虛擬)

F、I would rather you gave me the book.(同上)

G、It is necessary that we should clean the room everyday，(主語從句虛擬) H、He

speaks English so fluently as if he were English. (特殊從句虛擬)
