七年级英语下册教师辅导讲义一般现在时牛津版

【典型例题】
—____ Wang Fang have two small eyes?
—No, she has two big eyes.
A. Does B. Do C. Is D. Are
【解析】考查含实义动词的一般疑问句。句意:---王芳有两只小眼睛。----不,她有两只大眼睛。A行为动词have, has的疑问句分别由do, does引导。have由do引导;has由does引导,且has变为原形have,故选A。
(1)变一般疑问句:当句子中有be动词或情态动词时,则把be动词或情态动词(can,must等)提到句子的最前面,句末改问号。(口诀:变疑问并不难,be/情态动词提最前);
一般疑问句句式:Be+主语+表语?
e.g.①He is a teacher.一般疑问句→Is he a teacher? Yes, he is./No, he isn’t.
The sun rises in the east every day. The earth goes around the sun.
(5)表示平日的喜好
I like apples. She doesn’t like vegetables.
二、只有主语在第三人称单数时在陈述句里面实义动词用“三单形式”,其他人称(一,二,三复)用动词原形。
一般现在时态肯定句式:分为含有动词和实义动词的两种情况:
1.含有be动词的一般现在时的句式:肯定句式:主语+be+表语( n./adj.等)
e.g.①He is a worker.他是个老师
②You are nine.你9岁。
③They are in the classroom.他们在教室里面
含有be动词一般现在时态的句子转换:
变否定句:在be动词或情态动词后面直接加not变成否定句. (口诀:变否定最容易,not紧紧跟着be/情态动词)
否定句句式:主语+be+ not+表语:
例:①She is my sister..否定句→She is not my sister.②I can play soccer.否定句→I can not /can’t play soccer.

教学内容
一般现在时态
经常或习惯性的动作或一般性事实。也可表示现在的状态或主语具备的性格和能力。通常与副词every day(每天),always(总是),usually(通常),often(经常)sometimes(有时),等时间状语连用。
例:(1)表示事物或人物的特征、状态。
The sky is blue.天空是蓝色的。Mary’s father is an English teacher.玛丽的爸爸是一名英语老师。
2..-----Let’s play ping-pong.
------
A. It’s good B. That interesting C. Good idea D.You’re right
3.____ a big nose, but he ____ a small nose.
2.以字母s, x, ch, sh或o结尾的动词,在词尾直接加-es.watch---watches wash---washes do---does go---goes
(3)以“辅音字母加- y”结尾的动词,要先变y为i再加-es. try---tries study---studies cry---cries fly---flies 2.不规则变化:be---- is have----has
★Do you have a basketball?中do用实际意义吗?
→作助动词无意义,其第三人称单数是does;句中的do和does都是构成疑问句和否定句的助动词。
