主語、賓語、表語; (動名詞)

2. V-ing形式的被動式用法及種類
當v-ing與它的邏輯主語構(gòu)成被動關(guān)系時,要用其被動式, v-ing的被動式有兩種:一般被動式:being done;完成被動式:having been done; V-ing形式的被動式包括動名詞被動式和現(xiàn)在分詞的被動式兩種。
二、知識重點
考點/易錯點1
(一)動名詞的被動式
動名詞的被動式在句中可作主語、賓語、表語,且在句中只表被動,不表進行。
1、作主語
So being killed by sharks was a common thing. 因此被鯊魚吃掉是常有的事。
Being laughed at in public is a terrible thing.在公共場合下被嘲笑是件可怕的事。
Being exposed to the sun does harm to health.暴漏在陽光下對身體有害。
The president's being killed led to serious consequences.總統(tǒng)被殺導致了嚴重后果。
2、 作賓語
V-ing形式的被動式既可作動詞的賓語, 也可作介詞的賓語。
He was afraid of _________________ (abandon) by us.He did it without ___________ (ask)
You can't eat anything before _____________(operate on)I remember having been told the story.
3、作表語
What worried the child most was his not being allowed to visit his mother in the hospital.
使孩子最為擔心的是他不被允許到醫(yī)院看母親。
What I hate most is ________________ (laugh at)
The problem is for from _______________ (settle)
注意:①動名詞的被動式作主語和表語時,常用其一般式(being done),不習慣用完成式;但作賓語時,若其動作發(fā)生謂語動詞之前或強調(diào)動作已經(jīng)發(fā)生,可用其完成式(having been done)。如:
I appreciate having been given the chance to study abroad.
我很感激能被給與到國外留學的機會。
1)動名詞的被動式在句中作主、賓、表時,其特點是只表被動,不表進行。
2)動名詞的被動式作主、賓、表時,有時可采用其復合結(jié)構(gòu)形式,即:名詞所有格/形容性物主代詞+ being done。如:
Tom's being admitted to college is a big surprise for us.湯姆被大學入取讓我們很是驚訝。
The discovery of new evidence led to his being caught.新證據(jù)的發(fā)現(xiàn)導致他被捕。
�。ǘ┈F(xiàn)在分詞的被動式
現(xiàn)在分詞的被動式常句中作賓補和定語,一般不作狀語(除個別情形例外);在句中既表被動又表進行
1、 作賓補
現(xiàn)在分詞的被動式(being done)作賓補時,表示正在進行的被動的動作,常與感官動詞連用。
I saw James being held up in the water by old Tom.
You'll find the topic _______________ (discuss) everywhere now.
As we approached the village we saw new houses _____________ (build)
注意:與過去分詞作賓補的區(qū)別:過去分詞作賓補表示動作已完成.
2、作定語
現(xiàn)在分詞的被動式(being done)作定語時時,表示正在進行的被動的動作。
The meeting ______________ (discuss) now is very important.
He asked who was the girl _____________ (operate)on in the operating room.
注意:1)現(xiàn)在分詞的被動式作后置定語時,表示正在進行的被動的動作;過去分詞作后置定語表示已經(jīng)發(fā)生的被動的動作;不定式的被動式作后置定語表示未發(fā)生或即將發(fā)生的被動的動作。如:
a meeting being held now 正在被舉行的會議
a meeting heldyesterday 昨天舉行的會議
a meeting to be held tomorrow 明天將舉行的會議
2)現(xiàn)在分詞的被動完成式(having been done) 不能做定語和賓補。
The building having been built last year (×)The building built last year (√)
We found him having been killed. (×)We found him killed (√)
考點/易錯點2
現(xiàn)在分詞的被動完成式(having been done) 作狀語
當分詞與句子的主語構(gòu)成被動關(guān)系,且此分詞動作(明確地)發(fā)生在句子的謂語動詞之前或持續(xù)發(fā)生一段時間(或持續(xù)發(fā)生多次)時可用現(xiàn)在分詞的被動完成式(having been done) 作狀語。
Having been shown around the classroom, we were taken to visit the lab.
被領(lǐng)著參觀了教室后,我們又被帶著參觀了實驗室。
Having been told the news, they put off the trip.
被告知此消息后,他們?nèi)∠诉@次旅。
Having been separated for many years by the war, they couldn't recognize each other.
因戰(zhàn)爭而分離多年后,他們都認不出對方了。
Having been told many times, the boy still didn't know how to do it.
盡管被告知多次了,那個小男孩他仍然不知如何去做。
注意:1)若分詞有自己獨立的主語可構(gòu)成獨立主格結(jié)構(gòu)。
The work having been done,they left the office.
All the exam papers having been handed in, the teacher sent the students home.
2)在這種獨立主格結(jié)構(gòu)中,用現(xiàn)在分詞的被動完成式形式與用過去分詞形式差別不大。而為了簡潔,習慣采用過去分詞形式,如上面兩句常表達成:
The work done,they left the office.
All the exam papers handed in, the teacher sent the students home.
注意:過去分詞作狀語與現(xiàn)在分詞的被動完成式的區(qū)別:
二者作狀語時,都表示與句子的主語構(gòu)成被動關(guān)系,區(qū)別不大,可以互換。但是在這種情況下,為了簡潔,還是習慣采用過去分詞形式作狀語。
Asked(=Having been asked) to work overtime,I missed a wonderful film.
由于昨晚被要求加班,我錯過了一場精彩的電影。
Polluted (=Having been polluted) seriously, the water in the river was not safe to drink.
但是如果強調(diào)分詞動作發(fā)生在句子的謂語動詞之前或強調(diào)分詞動作持續(xù)發(fā)生多次發(fā)(或持續(xù)一段時間)還是習慣采用現(xiàn)在分詞的被動完成式(having been done) 作狀語,但終歸區(qū)別還是不大。
Having been told many times, he still repeated the same mistakes.
盡管被告訴了多次,他還是犯同樣的錯誤。
考點/易錯點3
動名詞的主動形式表被動意義
1、在want,need,require,deserve等動詞之后作賓語時,常用動名詞的主動式表示被動意義。
2、在(be)worth后面只能用動名詞的主動態(tài)來表示被動意義。
His suggestion is worth considering.
3、在allow,advise,forbid,permit等動詞后直接跟動名詞形式作賓語,如果后面有名詞或代詞作賓語,其后用動詞不定式作賓語補足語。如:
We don't allow smoking here. 我們不允許在這兒抽煙
We don't allow students to smoke here.我們不允許學生抽煙
