一般現(xiàn)在時(shí)是英語中應(yīng)用最廣泛的時(shí)態(tài)之一，是初中英語語法重點(diǎn)。它表示1)經(jīng)常性、習(xí)慣性的動(dòng)作或存在的狀態(tài)。e.g. I go to school on foot. He is very busy now. 2)表示主語的特征、性格、能力、愛好等。e.g. He can swim. I work hard. I like watching TV. 3)表示客觀真理 e.g. There are seven days in a week. The moon moves round the earth.

　　其結(jié)構(gòu)按正常語序，即“主語+謂語+其它”，有時(shí)為了起強(qiáng)調(diào)作用，時(shí)間狀語也可提前.

　　其句式變化可分為兩種情況 1)表示動(dòng)作， 一般人稱作主語的，變否定句須在動(dòng)詞前加助動(dòng)詞don’t;變一般疑問句須在句首加助動(dòng)詞do。 E.g. They have lunch at 12:00. They don’t have lunch at 12:00. Do they have lunch at 12:00? 2)單三人稱做主語的，變否定句須在動(dòng)詞前加助動(dòng)詞doesn’t;變一般疑問句須在句首加助動(dòng)詞does。

　　E.g. Jenny speaks English very well.

　　Jenny doesn’t speak English very well.

　　Does Jenny speak English very well?

　　含有be動(dòng)詞的要在be上做變化.

　　E.g. Danny is a good student.

　　Danny isn’t a good student.

　　Is Danny a good student?

　　其時(shí)間狀語為often、 usually、 always、 sometimes等頻率副詞，on Saturdays、 in the morning(afternoon evening) 、every day 等。

　　學(xué)生常見錯(cuò)誤如下：

　　一、be動(dòng)詞與行為動(dòng)詞同時(shí)出現(xiàn)在句子中

　　例：We are plant (plant) the trees in spring.

　　答案：plant

　　解析：學(xué)生往往會(huì)用漢語的思維方式去翻譯，就成了“我們是在春天植樹”。這是學(xué)習(xí)英語最忌諱的，要看語法是不是正確，在英語中，be是表狀態(tài)，do是表動(dòng)作，兩種動(dòng)詞不能同時(shí)出現(xiàn)在句子中，可記住如下口訣：“英漢語言有差異，be 、do不能放一起，仔細(xì)琢磨細(xì)分析，語法千萬要牢記。”

　　自我檢測(cè)：

　　(一)、 單選

　　1 Jenny ____ in an office. Her parents ____in a hospital.

　　A work; works B works; work C work; are working D is working; work

　　2 One of the boys_____ a black hat.

　　A like; listen B likes; listens C like; are listening D liking ; listen

　　6 Jenny____ English every evening.

　　A has study B studies C study D studied

　　答案：1 B 2D 3C 4B 5B 6B

　　(二)、填空

　　1 I can take Li Ming there when he _____ ( come) to visit.

　　2 _____your sister_____(know)English?

　　3Her home____ _____ ______(遠(yuǎn)離 )her school.

　　4The pot_____(not look) like yours very much.

　　5 Where _____you____(have)lunch every day?

　　6 Who_____(想要 )to go swimming?

　　7 ______she_____(do) the housework every day?

　　8 Jenny and Danny usually______(play) games in the afternoon .

　　答案：1 comes 2 Does know 3 is away from 4 doesn't look

　　二、單三人稱形式易出錯(cuò)

　　例：1 He plaies (play) football very well.

　　2 Danny gos (go) to school at 7:10.

　　答案：1 plays 2 goes

　　解析：1以輔音字母加y結(jié)尾的動(dòng)詞變單三人稱形式才能把y換成i再加es;2與名詞變復(fù)數(shù)不同，變單三人稱形式以o結(jié)尾的詞要加es.

　　三、在句式變換時(shí)易出錯(cuò)

　　例：1 Does Jenny has (has) a good friend?

　　2 Brian doesn’t lives (not live) in China.

　　答案：1 Does have 2 doesn’t live

　　解析：?jiǎn)稳朔Q做主語的一般現(xiàn)在時(shí)做句式變化時(shí)，可記住如下口訣：“見助動(dòng)，用原形”。此口訣也可推廣用于一般過去時(shí)態(tài)中。e.g. He didn't go home yesterday.

　　四、對(duì)do的理解易出錯(cuò)

　　例：We don’t (not do) our homework in the afternoon.

　　答案：don’t do

　　解析：do是一個(gè)比較難理解的詞，它有三個(gè)含義: a)是所有行為動(dòng)詞的總稱;b)是助動(dòng)詞，無實(shí)義;c)是一個(gè)具體的行為動(dòng)詞“做，干”。此句中給出的do指“做，干”，not指把此句變?yōu)榉穸ň洌薯氃赿o前加助動(dòng)詞don’t。

　　五、對(duì)主語的數(shù)判斷有誤

　　例： Li Ming with me are (be) in Beijing.

　　答案: is

　　解析:表面一看是“我和李明兩個(gè)人在北京”，但with在此做伴隨狀語，不能做主語，故用is.

　　另外，賓語從句中，從句部分若是表示客觀真理，不管主句是何時(shí)態(tài)，從句都要用一般現(xiàn)在時(shí);在時(shí)間和條件狀語從句中，主句表將來，從句要用一般現(xiàn)在時(shí)。
