職稱英語備考:職稱英語考試否定句易錯(cuò)考點(diǎn)(2)

字號(hào):


    5、你不必為你的軍銜和薪金擔(dān)心。
    誤:You won‘t have to worry about rank and pay.
    正:You won‘t have to worry about rank or pay.
    在肯定句中用and來連接兩個(gè)并列成分,表示“和”,但在否定句中and應(yīng)改為or, 這時(shí)否定詞對(duì)or的前后部分同時(shí)加以否定。
    6、這些規(guī)章制度多不完善!
    誤:How not perfect the rules and regulations are!
    正:How imperfect the rules and regulations are!
    漢語中的感嘆句可用否定式,如:多不光彩呀!多不容易呀!而英語中的感嘆句不能用否定式,我們可用反義詞或帶有否定詞綴的詞來表示。
    7、我認(rèn)為這不值得一試。
    誤:I think this is not worth trying.
    正:I don‘t think this is worth trying.
    英語中表臆想、猜測(cè)的動(dòng)詞think, believe, fancy, expect, guess, imagine, suppose等,如果帶有否定的賓語從句,賓語從句中的否定詞通常提前,用來否定主句的謂語動(dòng)詞。尤其是think, 按習(xí)慣用法,否定詞只能置于think前。
    8、他來這兒不是為了求得我們的幫助。
    誤:He came here not to ask us for help.
    正:He did not come here to ask us for help.
    否定狀語時(shí),英語中的否定詞一般不直接置于被否定詞語前,通常置于謂語動(dòng)詞前。只有當(dāng)兩個(gè)部分加以對(duì)比時(shí),即“不是……而是”時(shí),否定詞才可直接置于狀語前。如:他來這兒不是為了求得我們的幫助,而是來給我們提供一些信息。He came here not to ask us for help, but to give us some information.即使在這一結(jié)構(gòu)中,英語還是常把否定詞置于謂語動(dòng)詞前。
    9、他的設(shè)計(jì)肯定還沒完成。
    誤:He mustn‘t have completed his design.
    正:He can‘t have completed his design.
    對(duì)比較有把握的推測(cè),肯定句中用must,而否定句中用can‘t,對(duì)過去的推測(cè),在must和can’t后接完成形式。
