情態(tài)動詞
情態(tài)動詞表推測的三種句式
1.在肯定句中一般用must (一定),may(可能),might /can,could(也許,或許).(1)He must/may/might know the answer to this question?他一定/可能/也許知道這個問題的答案.
2.否定句中用can’t / couldn’t(不可能),may not/might not(可能不).(1)It can’t/couldn’t be the headmaster.He has gone to America.這不可能是校長,他去美國了.3.疑問句中用can/could (能……?).(1)Could he have finished the task?他可能把任務(wù)完成了嗎?(2)Can he be at home now?他現(xiàn)在能在家嗎?
注：以上三種句式中情態(tài)動詞的語氣按程度都是依次遞減的.Might,could并非may,can的過去式,而表示語氣較為委婉或可能性較小.
(二)情態(tài)動詞表推測的三種時態(tài)
1.對將來情況的推測,用“情態(tài)動詞 + 動詞原形”.
(1)She must / may / might / could arrive before 5.5:00前她一定/可能/也許到.
2.對現(xiàn)在或一般情況的推測,用“情態(tài)動詞 + be”,“情態(tài)動詞 +be doing”或“情態(tài)動詞 + 動詞原形”.(1)He must / may / might / could be listening to the radio now.他一定/可能/也許正在聽收音機(jī).
注：情態(tài)動詞 should /ought to表推測時,意為“想必會,理應(yīng)……”但與“have +過去分詞”連用時,則又可構(gòu)成虛擬語氣意為“本應(yīng)該做某事卻沒做”.例如：(4)It’s seven o’clock.Jack should/ought to be here at any moment.現(xiàn)在七點(diǎn)鐘了,杰克理應(yīng)隨時到達(dá).(推測) (5)She should / ought to have attended your birthday party,but she had to look after her mother in hospital.(虛擬) 她本該出席你的生日晚會的,可是她得在醫(yī)院照顧她媽媽.(6)Tom should not /ought not to have told me your secret,but he meant no harm.(虛擬) 湯姆本不該告訴我你的秘密,可是他并無惡意.
助動詞(auxiliary)主要有兩類：基本助動詞(primary auxiliary)和情態(tài)助動詞(modal auxiliary).基本助動詞有三個：do,have和be;情態(tài)助動詞基本的有十四個：may,might; can,could; will,would; shall,should; must,need,dare,used to,ought to.had better 上述兩類助動詞的共同特征是,在協(xié)助主動詞構(gòu)成限定動詞詞組
名詞性從句
主語從句
作句子主語的從句叫主語從句.主語從句通常由從屬連詞that,whether,if和連接代詞what,who,which,whatever,whoever以及連接副詞how,when,where,why等詞引導(dǎo).that在句中無詞義,只起連接作用;連接代詞和連接副詞在句中既保留自己的疑問含義、又起連接作用,在從句中充當(dāng)從句的成分.
賓語從句
名詞從句用作賓語的從句叫賓語從句.引導(dǎo)賓語從句的關(guān)聯(lián)詞與引導(dǎo)主語從句表語從句的關(guān)聯(lián)詞大致一樣,在句中可以作謂語動詞或介詞及非謂語動詞的賓語.
表語從句
在句中作表語的從句叫表語從句.引導(dǎo)表語從句的關(guān)聯(lián)詞與引導(dǎo)主語從句的關(guān)聯(lián)詞大致一樣,表語從句位于連系動詞后,有時用as if引導(dǎo).其基本結(jié)構(gòu)為：主語 + 系動詞 + that從句.例如：The fact is that we have lost the game.事實(shí)是我們已經(jīng)輸了這場比賽.That’s just what I want.這正是我想要的.
【注意】whether 可引導(dǎo)表語從句,但與之同義的if卻通常不用于引導(dǎo)表語從句.
同位語從句
同位語從句說明其前面的名詞的具體內(nèi)容.同位語從句通常由that引導(dǎo),可用于同位語從句的名詞有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等.
