【文章內(nèi)容簡介】 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 , getting４、一般過去時主要用來表示在特定過去時間中一次完成的動作或一度存在的狀態(tài)，也可表示過去的習(xí)慣動作。它與現(xiàn)在時間不發(fā)生關(guān)系，它表示的動作或狀態(tài)都已成為過去，現(xiàn)已不復(fù)存在。它經(jīng)常與表示過去的時間連用。如：I went to a park yesterday. I read a book last night. I watched TV yesterday evening.I went on a big trip last weekend. I failed my Chinese test. ☆注意☆ 一般過去時主要體現(xiàn)在動詞的形式要用過去式，動詞的過去式的構(gòu)成規(guī)則有：Ａ、規(guī)則動詞① 一般直接在動詞的后面加ed??；如 worked , learned , cleaned , visited② 以e結(jié)尾的動詞直接加d ；如 lived , danced , used③ 以輔音字母加y結(jié)尾的動詞要改y為i再加ed?。ù祟悇釉~較少）如 study – studied carry – carried worry – worried （play、stay除外）④ 雙寫最后一個字母（此類動詞較少）如 stopped Ｂ、不規(guī)則動詞（此類詞并無規(guī)則，須熟記）小學(xué)階段要記住以下動詞的原形和過去式：sing – sang , eat – ate , see – saw , have – had , do – did , go – went , take – took , buy – bought , get – got , read – read , fly – flew , am/is – was , are – were , say – said , leave – left , swim – swam , tell – told , draw – drew , e – came , lose – lost , find – found , drink – drank , hurt – hurt , feel – felt ☆注意☆句子的形式： 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.I’m going to buy a ic book tonight. He will eat lunch at 12:00.I’m reading a book. They are swimming.I watched TV yesterday evening. 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 four fans in our classroom.I’m not going to buy a ic book tonight. He will not (won’t) eat lunch at 12:00.I’m not reading a book. They are not (aren’t) swimming.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” 。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?
