四:動詞現(xiàn)在分詞詳解 動詞的ing形式的構(gòu)成規(guī)則:

　　① 一般的直接在后面加上ing , 如doing , going , working , singing , eating

　　② 以e 結(jié)尾的動詞,要先去e再加ing ,如having , writing

　　③ 雙寫最后一個字母的(此類動詞極少)有:running , swimming , sitting , getting

　　五:人稱代詞與物主代詞

　　一、人稱代詞

　　二、物主代詞

　　六:句型專項歸類

　　1.肯定句:是指用肯定的語氣來陳述的句子,如:I'm a student. She is a doctor. He works in a hospital.

　　There are four fans in our classroom. He will eat lunch at 12:00. I watched TV yesterday evening.

　　2.否定句:含有否定詞或表示否定意義詞的句子,如:I'm not a student. She is not (isn't) a doctor.

　　He does not (doesn't) work in a hospital. There are not (aren't) four fans in our classroom.

　　He will not (won't) eat lunch at 12:00. I did not (didn't) watch TV yesterday evening.

　　☆注意☆ 小結(jié):否定句主要是在肯定句的基礎(chǔ)上加上了否定詞 "not".有動詞be的句子則"not"加在be后面,可縮寫成"isn't,aren't",但am not 一般都分開寫.沒有動詞be的句子則要先在主要動詞的前面加上一個助動詞(do,does,did),然后在它后面加上"not",你也可以把它們縮寫在一起如"don't , doesn't , didn't ).這三個助動詞要根據(jù)人稱和時態(tài)來選擇,其中"does"只用于一般現(xiàn)在時主語是第三人稱單數(shù)的情況,而"did"只用于一般過去時,不論主語是什么人稱和數(shù),都用"did" .

　　3.一般疑問句:是指詢問事實的句子,此類句子必須用"yes",或"no"來回答.

　　如:Are you a student Yes, I am / No, I'm not.

　　Is she a doctor Yes, she is. / No, she isn't.

　　Does he work in a hospital Yes, he does. / No, he doesn't.

　　Are there four fans in our classroom Yes, there are. / No, there aren't.

　　Are you going to buy a comic book tonight Yes, I am. / No, I am not. (Yes, we are. / No, we aren't.)

　　Will he eat lunch at 12:00 Yes, I will. / No, I will not(won't).

　　Are they swimming Yes, they are. / No, they aren't.

　　Did you watch TV yesterday evening Yes, I did. / No, I didn't.

　　☆注意☆ 小結(jié):一般疑問句是在肯定句的基礎(chǔ)上,

　　①把動詞be調(diào)到首位,其他照寫,末尾標點符號變成問號即可.

　　②沒有動詞be的句子則要在句首加上一個助動詞(do,does,did)再把緊跟在后面的動詞變回原形,末尾標點符號變成問號即可.

　　這三個助動詞也要根據(jù)人稱和時態(tài)來選擇,其中"does"只用于一般現(xiàn)在時主語是第三人稱單數(shù)的情況,而"did"只用于一般過去時,不論主語是什么人稱和數(shù),都用"did" .一般疑問句有個重要的原則就是問和答要一致,即問句里的第一個單詞(助動詞)和簡略答句里的這個詞是一致的.
