英語四六級考試中,單獨考察語法的題型不多,但是語法知識點卻貫穿整張試卷,小伙伴們,趁著寒假,趕緊來打好基礎(chǔ)吧!下面是考試吧為大家整理的“大學英語六級基礎(chǔ)語法知識”供備考使用。
特殊虛擬語氣詞should
1) It is demanded / necessary / a pity + that…結(jié)構(gòu)中的主語從句的謂語動詞要用should 加動詞原形, should 可省略。
句型:
(1)suggested
It is important that…+ (should) do
(2) a pity
(1)suggested, ordered, proposed, required, demanded, requested, insisted; + (should) do
(2)important, necessary, natural, strange
a pity, a shame, no wonder
(3)It is suggested that we (should) hold a meeting next week.
It is necessary that he (should) come to our meeting tomorrow.
2)在賓語從句中的應(yīng)用
在表示命令、建議、要求等一類動詞后面的從句中。
order, suggest, propose, require, demand, request, insist, command, insist + (should) do
I suggest that we (should) hold a meeting next week.
He insisted that he (should ) be sent there.
注意: 如suggest, insist不表示"建議" 或"堅持要某人做某事時",即它們用于其本意"暗示、表明"、"堅持認為"時,賓語從句用陳述語氣。
The guard at gate insisted that everybody obey the rules.
判斷改錯:
(錯) You pale face suggests that you (should) be ill.
(對) Your pale face suggests that you are ill.
(錯) I insisted that you ( should) be wrong.
(對) I insisted that you were wrong.
3)在表語從句,同位語從句中的應(yīng)用
在suggestion, proposal, idea, plan, order, advice等名詞后面的表語從句、同位語從句中要用虛擬語氣,即(should)+動詞原形。
My idea is that we (should) get more people to attend the conference.
I make a proposal that we (should) hold a meeting next week.
