武漢新東方酷學(xué)酷玩夏令營為大家介紹主語的用法。

    武漢新東方酷學(xué)酷玩夏令營為大家介紹主語的用法。
    (1)由名詞、代詞(人稱代詞用主格)、動詞不定式、動名詞等充當(dāng),說明動作是“誰”發(fā)出的。如：the painter painted a very nice picture. (畫家畫了一幅漂亮的畫。) / they fought against sars bravely. (他們勇敢地與非典搏斗。) / to see is to believe. (耳聽為虛眼見為實(shí)). / helping animals is to help people. (幫助動物就是幫助人類。)
    (2)動詞不定式或動名詞做主語時(shí)可用it代替,而不定式或動名詞移至表語或賓語之后。如：it is very comfortable to have a class a seat during the long journey. (在長途旅行中能有個(gè)甲等座位簡直太舒服了。) / eating too much is bad for your health.(=it is bad for your health eating too much.) (吃得太多對你的身體不利。)
    (3)口語中常見主語或“主--系”省略：(it is) nothing. ((那)沒有什么。)/ (it) doesn’t matter. ((那)沒有關(guān)系。) / (i) thank you. ((我)謝謝你。)
    (4)反意問句的附加問句,主語必須是代詞：the man looks worried,doesn’t  he? (這個(gè)人看上去很著急不是嗎？) / tigers are dangerous animals, aren’t they? (老虎是危險(xiǎn)的動物不是嗎？)
    (5)祈使句一般省略主語。加主語時(shí)往往用來指定某個(gè)人。keep the keyboards clean, children. (孩子們請保持鍵盤的清潔。) (省略了主語) / you go there and fetch me a glass of water. (你去給我弄一杯水來。)
    (6)主語一般在句首,但在問句中會處于第二位和句尾；倒裝句及there be句型主語在動詞之后。如：computers are made in this factory. (計(jì)算機(jī)生產(chǎn)于這家工廠。) / where are they? (他們在哪兒？) / does the boy like staying home? (這個(gè)男孩喜歡呆在家里嗎？)
    (7)主語與謂語必須保持單、復(fù)數(shù)的一致, 而謂語與表語或賓語之間沒有這一要求。neither jim nor rose has passed the exam. (jim和rose都沒有通過考試。) / the chinese people are a hardworking and brave people. (中華民族是一個(gè)勤勞勇敢的民族。)
    (8)主語可以由從句充當(dāng),詳見“主語從句”。 【糾錯(cuò)】
