1、一般现在时现在进行时一般过去时一般现在时、现在进行时、一般过去时在七年级英语学习中我们主要学习了种时态， 即一般现在时、 现在进行时、 一般过去时。今天我们就将这种时态进行对比学习。一、 一般现在时定义 ：表示经常、反复发生的动作，经常存在的状态或者习惯性动作（有时间规律发生的事情）的一种时间状态。具体用法1. 表示经常的或习惯性的动作，常与表示频率的时间状语连用。（always,usually,often,sometimes, every day morning night eveningafternoonweek,）e.g. I go to school at 8:00 every mor
2、ning.2.表示主语具备的性格、能力、特征和状态及喜好等。e.gShe is 11 years old .I don t like English.She can speak English well.3.表示客观事实和普遍真理。e.g The earth moves around the sun.基本结构构成 :含有 be （ am 、 is 、 are ）动词的用法结构：肯定句 ： I am+ 其它You they we are + 其它She he it+is + 其它否定句 ： I am not+ 其它。You they we are not + 其它She he it+is +no
3、t + 其它一般疑问句及回答 ：单数： Are you +其它？肯定回答：Yes, I am.否定回答：No, I am not.Is she he it+其它？肯定回答: Yes,she he it is.否定回答:No,she he it is not.复数：Are you they you+其它？肯定回答 : Yes,we they are. 否定回答：从上面结构中你能总结出 be 动词的用法吗？单数_ ，你用 _ ， _-No, we they are not. _ ，复数连着她他它。_； 我用含实义动词的结构：肯定句：主语（ I, we, you,they, ） + 动词原形 +其它
4、。否定句：主语（ I, we, you, they ） +don t+ 动原 +其它。一般疑问句 ：Do + 主语（ you ,they ） + 动原 +其它？肯定回答 ; Yes, 主语（ I, we,you,they ） +do.否定回答 : No, 主语（ I ,we, you, they ） +don t.e.g. They get up at 6:00 every day. 你能帮它改个造型吗？否定句： _一般疑问句 _同志们回忆一下还有什么特殊情况我们还没讲到。当主语为第三人称单数时肯定句 主语 (she, he ,it) + 动词三单否定句 主语 (she, he ,it)+do
5、esn t+一般疑问句 Does + 主语 + 动词原形+ 其它 She plays chess well.动词原形 + 其它。 She doesn tplay chess well.+ 其它？ Does she play chess well?肯定回答否定回答Yes,No,主语主语+dose +doesn tYes, she does. No,she doesnt特殊疑问句特殊疑问词+ 一般疑问句？What does she play well?e.g. Mr. Yang teaches us math.否定句： _一般疑问句： _肯定回答 _动词第三人称单数的变化规则：1、一般情况加 S,
6、 e.g like-likes swim-swims2、以 s, x, sh, ch, 及 o 结尾的词加 es . e.g. watch watches3、以辅音字母加 y 结尾的词，要变 y 为 I 再加 es. E.g. study-studies.一、 句型变变变。这些句子要求 “变脸 ”，你能满足它们吗？1. Jeff has lunch at school. （改为一般疑问句）Jeff lunch at school?2. They have an English class every day. （改为否定句）They_ _an English class every day.3
7、 I am your English teacher.( 改为一般疑问句 )_ you our English teacher.4.Jim does his homework every day.( 改为否定句 )Jim _.二、 .单词 “化妆会 ”。小小单词就要登台演出了，你能帮助化妆吗？1.He doesn t play sports, he only w_them on TV.2.Tom _ （有） some English books. 3.The boy _ (not have) breakfast.4.Does your father _ （ like ） sports?二、现在
8、进行时定义 ：用来表示现在（说话瞬间）正在进行的动作和用来表示当前的活动或现阶段一直在进行着的动作。【注意】一些表示状态和意愿的动词，如 be,like,want,know ,think,have 等，不能用于现在进行时态中。如， I want to go home now.现在进行时的构成现在进行时由 be+v-ing 构成。 be 并不是助动词，而是 am is are 这三个 be动词。初学者最容易漏掉，它应与主语的人称和数保持一致。所以你们一定记好了，进行时的两重要部分， be 动词和 v-ing 这两者缺一不可。（ be 动词的选择相见前面be动词的用法）现在进行时的应用在实际运用时
9、，现在进行时常用以下几种情况：(1)当句子中有now 时，常表示动作正在进行，这时要用现在进行时。如：They are playing basketball now. 现在他们正在打篮球。(2)以 look, listen 开头的句子，提示我们动作正进行，这时要用现在进行时。如：Listen！ Sheis singing an English song. 听，她正在唱英语歌。(3) 表示当前一段时间或现阶段正在进行的动作，且此时有thisweek,thesedays等时间状语，这时常用现在进行时。如：We are practicing spoken English these days. 这些
10、天我们在练习英语口语。(4)描述图片中的人物的动作，也为了表达更生动。此时也常用现在进行时。如：Look at the picture. The children are flying kites in the park. 看这幅图，那些孩子正在公园放风筝。现在进行时的结构肯定句式 ：主语否定句式 ：主语+be( am,+be(am,is, is,are)+ 现在分词 + 其它are) +not + 现在分词.

11、它？ Is she playing chess now?肯定回答 ： Yes, 主语 +be. 否定回答： No, 主语 +be not特殊疑问句 ：疑问词 +be(am, is, are)+ 主语 + 现在分词 + 其它？现在分词的构成规则 :1 直接在动词原形末尾加 -ing, 如 play-playing work-working2 以不发音字母 e 结尾的动词，去 e 再加 -ing, 如 have-having write-writing3 以重读闭音节结尾的单词， 结尾只有一个辅音字母， 应双写这个字母， 再加 -ing。如，begin-beginningsit-sitting4
