1. 不定式、動(dòng)名詞作表語相當(dāng)于名詞,主語和表語是對(duì)等關(guān)系,位置可顛倒。分詞作表語相當(dāng)于形容詞,說明主語的性質(zhì)、狀態(tài),是從屬于主語的,主表位置不能顛倒。
Her job is taking care of the children.
她的工作是照料孩子。
Our duty is to train these students.
我們的職責(zé)是訓(xùn)練這些學(xué)生。
His report is very interesting .
他的報(bào)告很有趣。
I am pleased at the news.
我很高興聽到這個(gè)消息。
2. 不定式、動(dòng)名詞作表語比較:不定式作表語往往表示將來的行為;動(dòng)名詞作表語不受時(shí)間的限制。
My idea is to go there this morning.
我的想法是今天早上去那里。
Their work is producing TV sets .
他們的工作是生產(chǎn)電視機(jī)。
3. 動(dòng)名詞作表語時(shí)主語往往是抽象名詞work, job, aim, duty, habit, news, task, wish, pleasure, idea, hope等,表語進(jìn)一步說明主語的具體內(nèi)容。
My hobby is sleeping .
我的業(yè)余愛好是睡覺。
My aim is being a university student .
我的目標(biāo)是成為一名大學(xué)生。
4. 分詞作表語時(shí)其邏輯主語就是整個(gè)句子的主語,其區(qū)別在于:
1)現(xiàn)在分詞作表語時(shí)主語多是物,表語用來說明主語的性質(zhì),特征,意為“令人……的”
The film is quite moving .
這部電影很感人。
The news is surprising .
這個(gè)消息很令人吃驚。
2)過去分詞作表語時(shí)主語多是人,表語多表示主語所處的狀態(tài):
She looked disappointed .
她看上去很失望。
We were all moved at his words.
我們都對(duì)他的話很感動(dòng)。
3)注意這些詞的過去分詞與現(xiàn)在分詞在意義上的不同:interest, move, worry, please, disappoint, surprise, astonish, excite, touch, frighten。
I was interested in the interesting stories.
我對(duì)這些有趣的故事很感興趣。
