1.現在完成時
(1)現在完成時用來表示對目前狀況仍有影響的，剛剛完成的動作(常與yet，already，just連用)，或者過去某一時刻發生的，持續到現在的情況(常與for，since連用)。例如：#p#分頁標題#e#

四：時態一致
時態一致是英語四、六級考試的一個重要內容。通常應由主句謂語的時態決定從句的謂語時態。一般原則是：
1、當主句謂語使用現在時或將來時，從句的謂語根據具體情況使用任何時態
He says that he lives in Wuhan.
We hope that there will be many people at your party today.
Did you hear that Bill finally sold the house? Yes, but I dont know who bought it.
Theres a lot of excitement on the street.
There certainly is. Do you suppose the astronauts have returned?
2、當主句謂語使用過去時的時候，從句的謂語必須使用過去範圍的時態
He said he was writing a novel.
The teacher wanted to know when we would finish the experiment.
He said his father had been an engineer.
3、當從句是表示沒有時間概念的真理時，從句的謂語應使用一般現在時。例如：
The teacher told them since light travels faster than sound, lightning appears to go before thunder.
註：在此種情況下，即使主句謂語用了過去式的各種時態，從句謂語也應用一般現在時。
4、從句謂語只能用虛擬語氣的情況
利用時態一致原則確定從句動詞時態時，還應注意，若主語動詞是表示命令、請求、要求、建議、勸告等的動詞，從句謂語只能用虛擬語氣，不能遵循時態一致原則。例如：
We insisted that we do it ourselves.
動詞的語態
語態也是動詞的一種形式，英語有兩種語態：主動語態和被動語態。主動語態表示主語是動作的執行者，而被動語態表示主語是動作的承受者。
1)We use electricity to run machines. (主動語態)
2)Electricity is used to run machines. (被動語態)#p#分頁標題#e#
1.不能用於被動語態的動詞和短語
(1)在英語中，不及物動詞不能用於被動語態，但有些不及物動詞(包括短語)容易引起誤用。如：appear, belong, belong, die, escape, fall, happen, last, remain, succeed, occur, come true, take place, consist of。
(2)某些表示狀態或特徵的及物動詞，如：become, contain, cost, fit, have, resemble, suit也沒有被動語態。
2.被動語態的時態形式
常用的被動語態有表1所列的幾種時態形式。
表1
時?SPAN lang=EN-US> 一般時 進行時 完成時
現在 am asked am being asked
is asked is being asked
are asked are being asked
過去
was be asked was being asked
were be asked were being asked
將來 shall be asked shall have been asked
will be asked will have been asked
過去 should be asked should have been asked
將來 would be asked would have been asked
3.短語動詞的被動語態
短語動詞轉換為被動語態時，通常被看作是一個動詞，後面的介詞或副詞不能拆開或省略。例如：
1)So far no correct conclusion has arrived at.
2)All the rubbish should be got rid of.
4.get + -ed分詞的被動語態
get + -ed分詞結構強調動作的結果，而非動作本身，常用來表示突發性的，出乎意料的偶然事件。例如：
The boy got hurt on his way home from work.
另外，get + -ed分詞還可用於談論為自己做的事，是主動的行為而不是被動的行為。例如：
get dressed(穿衣服) get divorced(離婚)
get engaged(訂婚) get confused(迷惑不解)
get lost(迷路) get washed(洗臉)
get married(結婚)
5.能帶兩個賓語和複合賓語的動詞改為被動語態
(1)能帶兩個賓語的動詞改為被動語態時，一次只能由一個賓語作主語，另一個賓語被保留下來。例如：
1)We showed the visitors our new products.(主動語態)
2)The visitors were shown our new products.(被動語態)
3)Our new products were shown to the visitors.(被動語態)
(2)能帶複合賓語的動詞改為被動語態時，原來的賓語補足語變為主語補足語。例如：
1)The teacher appointed him League secretary.(主動語態)
2)He was appointed League secretary.(被動語態)
6.被動語態與系表結構的區別
(1)The novel was well written.(系表結構)
(2)The novel was written by Diskens.(被動語態)
7.少數動詞的主動語態有時有被動的意思
例1：The book is selling remarkably well.
例2：The song sounds very beautiful.
能這樣用的動詞還有read(讀起來)，clean(擦起來)，wash(洗起來)，write(寫起來)。#p#分頁標題#e#
例3：My watch needs cleaning. (= My watch needs to be cleaned).
能像need這樣用的動詞還有：want, require, deserve, do, owe, bind等。
例4：The meat is cooking.
例5：The book written by the professor is printing.
