說到 be 動(dòng)詞,,對(duì)大部分學(xué)生而言,既熟悉又陌生,,be動(dòng)詞常出現(xiàn)在日常英語(yǔ)學(xué)習(xí)之中,,但很多同學(xué)在使用be動(dòng)詞時(shí),卻容易出現(xiàn)錯(cuò)誤,,真的是既熟悉又陌生: 比如:我來自于重慶,! I am come from Chongqing. (錯(cuò)誤) She is go swimming every day. (錯(cuò)誤) 很多同學(xué)喜歡把 be 動(dòng)詞和實(shí)義動(dòng)詞原形連起來使用,特別是在口語(yǔ)表達(dá)和作文寫作中,! 初中英語(yǔ)需要記住一條規(guī)則:be動(dòng)詞是不能和動(dòng)詞的原形或三單形式連用,! 我們先來看一看be動(dòng)詞的各種形式: be(原形)- am/is/are(現(xiàn)在時(shí)態(tài))- was/were(過去式) - been (過去分詞)- being(現(xiàn)在分詞) 在使用be動(dòng)詞時(shí),要根據(jù)具體的時(shí)態(tài)與人稱選擇be動(dòng)詞,;其用法口訣為: 現(xiàn)在時(shí)態(tài):I 用 am,,you 用 are, is 跟著 他(he)她(she)它(it),,單數(shù) is,, 復(fù)數(shù) are; 過去時(shí)態(tài):am 與 is 的過去式為 was,;are 的過去式為 were,; I am a teacher. (I - am) You are a student. (you - are) He/she/it is from the UK. (he/she/it - is) The dog is brown. (單數(shù) - is ) The flowers are beautiful. (復(fù)數(shù) - are) We are good friends. (復(fù)數(shù) - are) 用法: 一、be動(dòng)詞作為系動(dòng)詞,; 構(gòu)成主系表結(jié)構(gòu),;be 動(dòng)詞可翻譯為“是” 或者無意義,只做連系作用,;be 動(dòng)詞后表語(yǔ)主要是說明主語(yǔ)的特征,,性質(zhì),屬性,,狀態(tài)等,;(be 后加not 構(gòu)成否定,be動(dòng)詞提前構(gòu)成疑問) She is thin. 她很瘦(他是瘦的),。 主語(yǔ)she,,is 為系動(dòng)詞,表語(yǔ) thin 說明 she 的特征,; The cat is cute. 這只貓很可愛(貓是可愛的),。 主語(yǔ) the cat, is系動(dòng)詞,,表語(yǔ) cute 說明 the cat 的特征,; He was at home. 他(是)在家。 主語(yǔ) he,,is 系動(dòng)詞,,表語(yǔ) at home 說明主語(yǔ)he的狀態(tài); 二,、be 用作助動(dòng)詞可構(gòu)成時(shí)態(tài)語(yǔ)態(tài) be + doing 構(gòu)成進(jìn)行時(shí)態(tài) am/is/are + doing 現(xiàn)在進(jìn)行時(shí) was/were + doing 過去進(jìn)行時(shí) (be 后加not 構(gòu)成否定,,be動(dòng)詞提前構(gòu)成疑問) He is (not)reading books now. 他正在(沒有)讀書。 I was watching TV at 8:00 yesterday. 昨天八點(diǎn)時(shí),,我正在看電視,。 Are they playing football outside. 他們正在外面踢足球嗎? be + going to 構(gòu)成將來時(shí)態(tài),,表示打算,,將要做... am/is/are + going to 一般將來時(shí) was/were + going to 過去將來時(shí) (be 后加not 構(gòu)成否定,be動(dòng)詞提前構(gòu)成疑問) I am going to visit my uncle. 我打算去拜訪我的叔叔,。 They are going to do some shopping this weekend. 這周末他們打算去購(gòu)物,。 He told me that he was not going to study the guitar. 他告訴我他不打算學(xué)習(xí)吉他。 be + done(過去分詞) 構(gòu)成被動(dòng)語(yǔ)態(tài) (be 后加not 構(gòu)成否定,,be動(dòng)詞提前構(gòu)成疑問) This book was written by Jeff Green. 這本書是(被)杰夫格林所寫,。 The bad man was caught by the police. 那個(gè)壞人被警察抓了,。 在含有be動(dòng)詞的句子中(做謂語(yǔ)或系動(dòng)詞),be + not構(gòu)成否定,,be動(dòng)詞提前構(gòu)成疑問,; 但當(dāng)句子中有其他助動(dòng)詞時(shí),如 have(完成時(shí)態(tài)),,will,,情態(tài)動(dòng)詞等;不使用be動(dòng)詞構(gòu)成否定,,疑問,; He will be our new English teacher. 他將成為我們的新英語(yǔ)老師。 He will not be our new English teacher. I have been an English teacher since 2008. 我從2008年以來就一直是個(gè)英語(yǔ)老師,。 Have you been an English teacher since 2008? 注意:在以be動(dòng)詞開頭的祈使句中,,如需否定,需要在be前加 don't. Don't be noisy. 別吵,! there be 句型,,表示“某處有某物” There are 45 students in our class. 我們班有45個(gè)學(xué)生。 Are there 45 students in your class? 你們班有45個(gè)學(xué)生嗎,? How many students are there in your class? 你們班有多少學(xué)生,? 注意:There be 句型就近原則,即be動(dòng)詞的選擇需要根據(jù)距離其最近的名詞單復(fù)數(shù)決定,; 如: There are three books and one pen on the desk. There is one pen and three books on the desk. 桌上有一只鋼筆,,三本書。 初中英語(yǔ)300動(dòng)詞,,中學(xué)生必須掌握的詞,!持續(xù)更新,點(diǎn)擊關(guān)注,,轉(zhuǎn)發(fā),! |
