【—之主語】對(duì)于英語中主語語法知識(shí)的講解內(nèi)容，同學(xué)們認(rèn)真學(xué)習(xí)下面的講解。

　　主語：

　　(1)由名詞、代詞(人稱代詞用主格)、動(dòng)詞不定式、動(dòng)名詞等充當(dāng),說明動(dòng)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(dòng)物就是幫助人類。)

　　(2)動(dòng)詞不定式或動(dòng)名詞做主語時(shí)可用it代替,而不定式或動(dòng)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(duì)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(dòng)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(qǐng)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(huì)處于第二位和句尾；倒裝句及there be句型主語在動(dòng)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?cè)谀膬海? / 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。)

　　希望上面對(duì)英語語法主語的講解內(nèi)容，同學(xué)們都能很好的掌握，相信同學(xué)們會(huì)學(xué)習(xí)的很好的。
