2016屆高考英語(yǔ)第一輪語(yǔ)法大全復(fù)習(xí)教案及配套練習(xí)4
3)在表語(yǔ)從句,同位語(yǔ)從句中的應(yīng)用
suggestion, proposal, idea, plan, order, advice等名詞后面的表語(yǔ)從句、同位語(yǔ)從句中要用虛擬語(yǔ)氣,即(should)+動(dòng)詞原形。例如:
my idea is that we(should)get more people to attend the conference.我的想法是讓更多的人來(lái)參加會(huì)議。
i make a proposal that we(should)hold a meeting next week.我提了個(gè)建議,下周我們開個(gè)會(huì)。
16.6 wish的用法
1)wish后面的從句,表示與事實(shí)相反的情況,或表示將來(lái)不太可能實(shí)現(xiàn)的愿望。其賓語(yǔ)從句的動(dòng)詞形式為:
主句 從句
從句動(dòng)作先于主句動(dòng)詞動(dòng)作(be的過(guò)去式為 were) 現(xiàn)在時(shí) 過(guò)去時(shí)
從句動(dòng)作與主句動(dòng)作同時(shí)發(fā)生(had + 過(guò)去分詞) 過(guò)去時(shí) 過(guò)去完成時(shí)
將來(lái)不大可能實(shí)現(xiàn)的愿望 將來(lái)時(shí) would/could +動(dòng)詞原形
例如:i wish i were as tall as you. 我希望和你一樣高。
he wished he hadn\'t said that. 他希望他沒講過(guò)那樣的話。
i wish it would rain tomorrow. 我希望明天下雨就好了。
2)wish to do;wish sb / sth to do。例如:
i wish to see the manager. = i want to see the manager. 我希望見一見經(jīng)理。
i wish the manager to be informed at once. (= i want the manager to be informed at once.)我希望經(jīng)理能馬上得到消息。
16.7 比較if only與only if
only if表示\"只有\(zhòng)";if only則表示\"如果……就好了\"。if only也可用于陳述語(yǔ)氣。例如:
i wake up only if the alarm clock rings. 只有鬧鐘響了,我才會(huì)醒。
if only the alarm clock had rung. 當(dāng)時(shí)鬧鐘響就好了。
if only he comes early. 但愿他早點(diǎn)回來(lái)。
16.8 it is (high) time that
it is (high) time that 后面的從句謂語(yǔ)動(dòng)詞要用過(guò)去式或用should加動(dòng)詞原形,但should不可省略。例如:
it is time that the children went to bed. 孩子們?cè)撍X了。
it is high time that the children should go to bed.
16.9 need \"不必做\"和\"本不必做\"
didn\'t need to do表示過(guò)去不必做某事, 事實(shí)上也沒做。
needn\'t have done表示過(guò)去不必做某事, 但事實(shí)上做了。例如:
john went to the station with the car to meet mary, so she didn\'t need to walk back home.
約翰開車去車站接瑪麗,所以她不必步行回家了。
john went to the station with the car to meet mary, so she needn\'t have walked back home.
約翰開車去車站接瑪麗,所以她本不必步行回家了。 (mary步行回家了,沒有遇上john的車。)
典型例題
there was plenty of time. she ___.
a. mustn\'t have hurried b. couldn\'t have hurried c. must not hurry d. needn\'t have hurried
答案d。needn\'t have done. 意為\"本不必\",即已經(jīng)做了某事,而時(shí)實(shí)際上不必要。
mustn\'t have done 用法不正確,對(duì)過(guò)去發(fā)生的事情進(jìn)行否定性推斷應(yīng)為couldn\'t have done, \"不可能已經(jīng)\"。 must not do 不可以(用于一般現(xiàn)在時(shí))。
17. 名詞性從句
在句子中起名詞作用的句子叫名詞從句。名詞從句的功能相當(dāng)于名詞詞組, 它在復(fù)合句中能擔(dān)任主語(yǔ)、賓語(yǔ)、表語(yǔ)、同位語(yǔ)、介詞賓語(yǔ)等,因此根據(jù)它在句中不同的語(yǔ)法功能,名詞從句又可分別稱為主語(yǔ)從句、賓語(yǔ)從句、表語(yǔ)從句和同位語(yǔ)從句。
