成人英語三級考試高分語法指導(dǎo)下

以下是為大家整理的關(guān)于成人英語三級考試的文章，供大家學(xué)習(xí)參考！
    注意1：部分動詞的賓語從句中需用虛擬語氣，形式為should do, 其中should常被省略。
    此類動詞有：insist, demand, suggest, propose, order, require, decide,ask, request等.
    例句： We all insist that we (should) not rest until we finish the work.
    The professor suggests that the students (should) collect enough mate rials before they work on this project.
    上面的動詞如果以名詞形式出現(xiàn)時，后面的that從句仍然要采用虛擬語氣
    He gives me the suggestion that I (should) eat breakfast every moning.轉(zhuǎn)自環(huán) 球 網(wǎng) 校edu24ol.com
    注意2：在一些慣用語之后經(jīng)常需要用虛擬，來表示與事實相反或者難以實現(xiàn)的事情這類習(xí)語有： as if , as though, but for, otherwise, without, wish, if　only等
    例句： But for your help, I would not have arrived here in time.轉(zhuǎn)自環(huán) 球 網(wǎng) 校edu24ol.com
    (如果沒有你的幫助，我就不能準時到達)
    Without your help, I would not arrive here in time.
    注意3：在下列形容詞引導(dǎo)的that從句中必須要用虛擬語氣(should) do，但是由于 should經(jīng)常被省略，所以實際上用的就是動詞原形。
    這類形容詞有: It is important/ necessary/ proper/ imperative/ essential/advisable等 + that
    例句：It is necessary that he (should) realize his situation.
    一致原則
    一致原則貫穿英語語法，在前面各個章節(jié)中已有涉及，本章作為對前面的補充，集中講、TOEFL題中?？嫉膯栴}
