Question

如题所述

Answer 1

仁爱版八年级上学期英语重点语法项目一、 be going to 结构
1) 表示计划、安排及打算
2) 条件句中，一般用will/shall 结构代替be going to 结构。
If it doesn't rain tomorrow ,we _________
(就来) to your home
If he agrees with us ,he ________(成为)a member .
3) there are /is going to be =there will be
We will have a meeting in your classroom this Friday .=there is going to be a meeting in our classroom this Friday .
仿写：he will have a party in his home tomorrow .=________________________.
选填：there is going to ______ (have/be) a tall building over there next year .
4) 表示位置移动的词，在be going to 结构中往往用进行时代替。如：come ,return ,go ,arrive ,leave .
He is going to come here soon .=he is coming soon .
仿写：They are going to arrive in an hour .
= ___________________________ .
5)按自然规律一定要发生的事情，一般用will 而不用be going to 结构：
译出：明天就是元旦节了。
二、主语+will /shall+动词原形+。。。 结构 表示将要发生的事情。
1 一般情况下，与be going to 结构可以互换。
We shall make a visit to him next month .
= _______________________________ .
2 条件状语从句和时间状语从句中，一般用will/shall 结构。
If he ______(not come ) tonight ,we _____
(not hold the party).
3 shall 与will 不可搞混。
练习：变为一般疑问句、否定句、特殊疑问句。
1) We shall stand up.
2) I shall call for help in such an situation .
3）he will help us with our work .
三、can 、may 、must 注意事项
1 过去式：can---could ;may---might .must 没有人称、数、时态变化。
He can swim now .
He could swim three years ago .
You must tell the truth .
He must tell the truth .
2 否定回答以及变为否定句时，它们的变化规律如下：
can—cant ;may –mustn’t
Must---needn’t/ don't have to ;
need---needn’t
练习：将下列句子分别变为否定句、一般疑问句并作否定回答。
1）I can swim
2）He must hand it in now.
3) She need answer the door at once .
4) The little boy can also come here .
3 当这几个词表示推测时，否定句通常都用can’t。
练习：改为否定句。
1 )he can be in the teacher’s office
2) It may be raining in the south of China recently .
3) You must be right .
四、had better 和不定式的否定形式。
had better do sth ---- had better not do sth .
to do sth --- not to do sth 。
译出:晚上你最好不要外出。
我想他不和你一块儿去。
五、一般过去时和过去进行时
1 以过去某个时间为基准：动作已经结束的，用一般过去时，动作正在进行的，用过去进行时。
1) He was busy all this morning ,he _____
(write) a novel .
2) He ______ (put) on his coat and went out .
2 由when 和while引导的时间状语从句中，发生在前面且持续时间久的动作用过去进行时，发生在后面，持续时间短的用一般过去时。
1)when we ______ (lie) in bed ,he_____
(come) in .
2) They ______ ( begin) their lessons when it _______ (happen).
3) While you _____ (pass)the post office , he ______(see) you.
六、比较级和最高级
1) 形容词或副词前有a little(bit) ,even（更） much（比…得多）时，该形容词或副词用比较级形式。
练习：用词的适当形式填空。

2 比较级前不加the，但句中有of 时 例外。
1）which do you like ______(good), PE or music？
2 I like music _____ (good) of the two subjects ?
3 ) She is _____ (beautiful) of the twins .
3 比较级和最高级可以转变，意思不变。

He is clever than any other student in our class .
练习：变为最高级或者比较级。
Chang jiang is the long river in China .
He is short than any other in his class.
4 最高级变为比较级时，如果句子主语跟后面表示范围的词具有所属关系时any后要加other ,否则，不要other .
练习：用any 、any other 填空。
The desk is more expensive than _______
One in this shop.
The desk in this shop is more expensive
than ______ one in that shop.
5 比较对象相同时，可用that /those 代替另一比较对象。That 用于单数或者不可数，those 用于复数。
