當主句是現(xiàn)在時時，賓語從句根據(jù)具體情況選擇合適的時態(tài)；當主句是過去時時，賓語從句只能用過去的時態(tài)；但是如果賓語從句表示客觀事實或真理，不管主句是何種時態(tài)，

從句都要用一般現(xiàn)在時。Ididn’tknowwhathe____________(do)whenIphonedhim.Icanstillrememberthatshe___________(be)ahappygirlatthattime.Heisproudthathe_________________(achieve)allhisgoalssofar.Asachild,Iwastoldthatthemoon_________(have)nolightofitsown.Ididn’tbelieveit.wasdoingwashasachievedhas二．賓語從句：4.兩個需要注意問題：(2)否定轉(zhuǎn)移:主句謂語是think,believe,suppose,expect,imagine等動詞，且主語為_______人稱時，賓語從句中的否定詞要轉(zhuǎn)移到_________中，即主句的謂語動詞用________形式，而從句的謂語動詞要用_________形式。我想我不能在兩小時內(nèi)記住這100個單詞。___________________________the100wordswithintwohours.

，且不是所有名詞都可以用同位語從句修飾。定語從句“修飾、限定”它所修飾的名詞即先行詞，且先行詞在從句中必須充當成分。

從句)that(should)carrythat(should)do不充當成分that同位語that定語六．需要注意的幾個問題：1.wh-ever和nomatterwh-的區(qū)別：

wh-ever既可以引導(dǎo)名詞性從句，又可以引導(dǎo)讓步狀語從句，而nomatterwh-只能引導(dǎo)讓步狀語從句。
