仁爱版初二英语第一单元

一般现在时

1. 概念：一般现在时。表示通常性、规律性、习惯性的状态或者动作（有时间规律发生的事件）的一种时间状态。

2. 1)

时间状语：every„，sometimes， at„，on Sunday He often wakes up at 7 every morning. 2) 客观真理，客观存在，科学事实。

The earth moves around the sun. Shanghai lives in the east of China. 3) 表示格言或警句中。 Pride goes before a fall.骄者必败。（ 注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。例：Columbus proved that the earth is round.）

4) 现在时刻的状态、能力、性格、个性。eg. I don't want so much./Ann Wang writes good English but does not speak well.比较：Now I put the sugar in the cup./I am doing my homework now.第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。再如：Now watch me,I switch on the current and stand back. 第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。

5）时间、条件、方式、让步状语从句中代替一般将来时。例：If it doesn't rain, we'll go on a picnic as planned. 3.基本格式

4.变化规律

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____ _____ ______(远离 )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 5 do have 6 wants 7 does do 8 play 二、单三人称形式易出错

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以辅音字母加y结尾的动词变单三人称形式才能把y换成i再加es；2与名词变复数不同，变单三人称形式以o结尾的词要加es. 三、在句式变换时易出错

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：单三人称做主语的一般现在时做句式变化时，可记住如下口诀：“见助动，用原形”。此口诀也可推广用于一般过去时态中。e.g. He didn't go home yesterday.

四、对do的理解易出错

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

解析：do是一个比较难理解的词，它有三个含义:

a)是所有行为动词的总称；b)是助动词，无实义；c)是一个具体的行为动词“做，干”。此句中给出的do指“做，干”，not指把此句变为否定句，故须在do前加助动词don’t。 五、对主语的数判断有误

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

解析:表面一看是“我和李明两个人在北京”，但with在此做伴随状语，不能做主语，故用is. 另外，宾语从句中，从句部分若是表示客观真理，不管主句是何时态，从句都要用一般现在时；在时间和条件状语从句中，主句表将来，从句要用一般现在时。

现在进行时

1. 概念：现在进行时表示现在（说话的瞬间）正在进行或发生的动作。所谓“正在进行中”，是指在谈到这件事的时候，这个动作还在进行中。

2. 现在进行时的构成是:主语+be+v.ing〔现在分词〕形式

第一人称单数I+am+V-ing. 第一人称复数We+are+V-ing.

第二人称单(复)数 You+are+V-ing

第三人称单数 He（She，it）+is+V-ing

第三人称复数 They+are+V-ing 肯定句:主语+be（is/am/are）+现在分词 否定句：主语+be（is/am/are）+not+现在分词 一般疑问句:be（is/am/are）+主语+现在分词

特殊疑问句：特殊疑问词+相应be动词+主语+现在分词+Sth? 间接引语中改为过去进行时。

3. 变化规则直接+ ing(例：sleep+ing sleeping)

去掉不发音的e+ing(例：bite-e+ing biting)

重读闭音节，以辅音字母加元音字母加辅音字母结尾的词，要双写尾字母再加ing（例：swim+m+ing=swimming)

以ie结尾的重读闭音节，变ie为y+ing （例：die-dying lie-lying）

结尾为c且c读作/k/时，在结尾加k再加ing,如picnic-picnicking 练习题：

1. What are you _________(do) now? I ___________(eat) bread. 2. It’s nine o’clock. My father_______________(work) in the office. 3. Look, the boy____________(put) the rubbish into the bin.

4. __________he__________(clean) the classroom? No, he isn’t. He____________(play).

5. Where is Mak? He___________(run) on the grass. 6. Listen, who____________(sing) in the music room? Oh, Mary_____________(sing) there. 将下列句子改成现在进行时
