新概念49～72课之前知识点总结

新概念49～72课之前知识点总结
新概念1～72课的内容主要是集中在4个时态：一般现在时、现在进行时、一般将来时和一般过去时
还有句子的基本结构：肯定句、否定句、一般疑问句和特殊疑问句
同时，还有祈使句以及情态动词！！！
如果这些知识没学扎实孩子也无需担心，没关系，新概念这本书好就好在，抓住学生特点-----容易忘！所以后续的课程会一直在重复出现上述的知识点，而72课之前，只是浅浅带出基本知识点！所以，后面要好好去体会了！这里，我已经给你总结好了，你看看，有哪些你没掌握？
一、Lesson49-52
★Key point:
一般现在时
定义：描述一般性事件、规律性、日常性发生的事或是客观事实。

一般时大部分描述的是日常的生活，我每天刷牙三次（早中晚）；我每天都上班；你早上起床总是把鞋穿反；你每天上课都不举手回答问题…….
客观事实是什么？就是太阳东升西落；光的速度比声音快；还有我很帅！！！
例句：⒈ I go to school every day. (一般性)
⒉ Peterusually brushes his teeth three times a day.（规律性）
⒊ Thesun rises in the east and sets in the west.（客观事实）
类型：
肯定句
Ⅰ.带有动词句子，应注意“三单”使用：
例：I like apples. / He likes pears. / She likes strawberries.
Ⅱ.带有Be动词句子，应注意随主语变化而变化Be动词：
例：Iam a teacher. / He is a worker. / She is a dancer. They are students. / We arehappy.
肯定句总结：即：掌握动词有“三单”变化，遇到“He, she, it 或一个人、一个物”都要变化动词形式，不能全部使用“原形”。

同时还要清楚，除了动词之外还有Be动词，它有三种形式“is ,am ,are”，随主语变化而变化。

否定句
Ⅰ. 带有动词句子的否定，采用“见动词，找助动”口诀：
例：I don’t like apples. / He doesn’t likepears. / They don’t understand. /We don’t want to do homework.
Ⅱ. 带有Be动词句子的否定，在Be动词后加NOT即可：
例：I am not a teacher. / She is not a baby. / We are notstudents.
否定句总结：即：掌握“见动词，找助动，找助动，看主语”口诀，攻克动词句子的否定；
而带有Be动词句子，只要在原句的Be动词之后加NOT即可.
疑问句
主要掌握2个助动词Do和Does；Do用在复数主语（I, We, They 和许多人），Does用在单数主语（he, She, It和一个人）。

一般疑问句：即以助动词Do、Does或Be动词Is、Am、Are开头提问的疑问句，回答全部采用Yes或No来作答。

例：Do you go to school every day?
-Yes, I do.
Does he brush his teeth three times a day?
-Yes, he does.
Are you a teacher? – No, I am not.
Is it a dog? –No, it isn’t.
特殊疑问句: 即采用特殊疑问词“What,when,where,which,why,how”等特殊疑问词开头的疑问句。

例：Whereis your mother? – She is in the shop.
选择疑问句：即由or作连词连接的两个具有选择的疑问句
例： Do you want beef or lamb? – Beef, please.
特殊疑问句总结：分两类来记，即带有动词的特殊疑问句和带有Be动词特殊疑问句：特殊
疑问词 + 助动词（Do或Does）+ 主语 + Do（动词原形）
WHAT + DO + YOU + WANT?
WHERE + DOES + SHE + COME FROM？
★ Keysentences:
1. Do you want any meat?
疑问句中，一些不可以再用“some”而是换成any
Do you want beef or lamb? 选择疑问句，用or连接，二者选其一
2. What about some steak? 表示询问或是给建议时的疑问句，要用some
3. What’s the weather like in spring?
What’s …. Like?句型，表示询问怎么样
What’s the climate like in yourcountry?
询问国籍的几种问法：
Where do you come from? / Where do they come from?/ Where doeshe come
from?/ Where does she come from?
Where are you from?/ Where are they from?/ Where is your mother from?/ Where is Lily from?
二、Lesson53-54
继续复习前面所学一般现在时，又给出了新的询问国籍的句式：

★情态动词和祈使句
褚老师讲情态动词：
情态动词按语气强弱，可以分“小强”和“小妹”级别：
▲最强的“小强”： Must（语气很强烈，不敢惹）
使用频率最多的“小能”： Can（什么都能做）
“小能”的胞弟“小酷”： Could（请求别人帮助）
“小酷”的好兄弟“小悟”: Would（给别人提供一些东东）
还有大家最熟悉的： Should（大家都会用，“应该”）
▼最弱的“小妹”: May
还有“小妹妹”： Might（语气弱到不行）
主语+ Must/ can/ could/ may/ should/need + DO（动词原形）
注意情态动词是没有变化形式的，永远都是用原形，也不受主语限制，不管是否三单，都只用原形。

没有cans,musts,shoulds
例： We must study hard.
He need do some sports.
祈使句：其实很简单，就是指命令或是请求，都是由动词原形构成的简单句！Take this medicine! 吃药！（请求） Open the door! 开门！（请求）Don’t smoke here! 别在这吃药！（命令）
Don’t play with matches! 别玩火柴！（命令）
You mustn’t lean out of thewindo w!不要将身体探出窗外！（命令）

一般疑问句：就是将Be动词提前于句首即可
特殊疑问句：特殊疑问词 + Be + 主语 + going to + Do（原形）
WHAT+ ARE + YOU + GOING TO + DO?

六、Lesson69-72

★There be 句型：
表示存在，尤指某地有某物的说法

3.绝不可出现have：
× There has three hundredstudents in the hall.
√There are three hundred students in the hall.
★介词口诀:
