八年级英语语法【第二篇】
感叹句的类型：
⑴ What a∕an+adj+可数名词单数 (+主语+谓语)!
What +adj+可数名词复数∕不可数名词 (+主语+谓语)!
What a fine day (it is) !多么好的天啊！ (day为可数名词单数)
What an interesting book it is !多么有趣的一本书啊！(book为可数名词单数)
What beautiful flowers they are !多么漂亮的花啊！ (flowers为可数名词复数)
What bad weather it is!多么糟糕的天气啊！(weather为不可数名词)
⑵ How +adj +主语+(谓语中的)系动词！ How +adv +主语+(谓语中的)实义动词！
How happy I am!我多麽高兴啊！ (happy为adj,am为系动词)
How hard they are working !他们工作多么努力啊！(hard为adv,work为实义动词)
点拨：陈述句改为感叹句，可以采用“一判、二定、三移”。
一判：是判断出陈述句谓语动词后的中心词的词性(adj∕adv∕n);
二定：是根据判断出来的结果来确定引导词(中心词为名词用What;中心词为形容词或副词用How;)
三移：就是把主语和谓语移到后面。
注意：在感叹句中，不得出现so,very，very much等表示程度的单词。
例如：①Our school is beautiful .
一判：beautiful为形容词；二定：beautiful为形容词，用How 来引导；三移：把Our school is移到How beautiful后面，即为感叹句How beautiful our school is!
②He is a clever boy.
一判：boy为名词；二定：boy为名词，用What来引导；三移：把He is移到What a clever boy 后面，即为感叹句What a clever boy he is!
③He studies English well.
一判：well为副词；二定：well为副词，用How 来引导；三移：把He studies移到How well后面，即为感叹句How well he studies!
练习：将下列句子变为感叹句。①The room is very bright.
② We live a happy life today. ③It is a nice present.
④This is difficult problem. ⑤She played the piano wonderfully.
(best) way to do sth:做某事的()方法
for+名词V?ing:为什么而感谢
a trip参加郊游，at the end of this month在本月底
back to+地点：回到某地 He will go back to Beijing in 2 days.两天后他将回北京。
a surprise party for sb为某人举办一个惊喜的晚会
+名词代词 V?ing：没有… He can't finish the work without our help.(help为名词)
He went to school without having breakfast.他没有吃早饭就去上学。(have为动词)
forward to +名词代词：期待，盼望
from sb.收到某人的来信 = receive a letter from sb.
opening of… ：开幕/开业
10.在具体哪一天的上午、下午、晚上用on,比较：
in the morning在早晨 on Sunday morning在星期天的早晨
sb to +地点：邀请某人去某地(invite -- invitation ) invite sb to do sth 邀请某人做某事
to sth / sb：回答某事/回答某人 go shopping 购物，do homework做家庭作业
学习一般将来时will do sth。
一般将来时由“助动词will / shall + 动词原型”构成，表示将来某个时间要发生的动作或存在的状态，常与表示将来的时间状语如tomorrow、next week，in 2 days(2天之后)等连用。(Shall用于第一人称，will可以用于各种人称。) (will not= won't)
一般疑问句：把肯定句中的will 提到句首即可。以上两句的一般疑问句为：
Will you visit the old man next week? Yes,we , we won't .
否定句：把肯定句中的will 变为won't即可。以上两句的否定句为：
We won't visit the old man next week. She won't finish the work in 2 weeks.
不定代词和不定副词的用法：
(1)左边的some、any、every、no与右边的body、one、thing构成不定代词，some、any、every、no与右边的疑问副词where构成不定副词；
(2)一般情况下以some开头的不定代词和不定副词用于肯定句，以any开头的不定代词和不定副词用于否定句、疑问句；以no开头的不定代词和不定副词表示否定含义(no one为两个单词);
(3)不定代词或不定副词和形容词连用时，形容词放在后面。
He has something important to do.他有重要的事情要做。(肯定句用something，形容词important放后)
Did you buy anything special? (一般疑问句用anything，形容词special放后)
Did you go anywhere interesting last month?上个月你去令人感兴趣的地方了吗？
(一般疑问句用不定副词anywhere，形容词interesting放后)
(4)不定代词和不定副词做主语时，后面的动词用单数形式。Everone is here today.今天每个人都在这里。

八年级下册英语语法【第四篇】
1. 表示将要发生的动作或存在的状态。本时态标志词：
① 含 tomorrow; next 短语；② in + 段时间 ;③ how soon;
④ by + 将来时间；⑤ by the time sb. do …;⑥ 祈使句句型中：or/
and sb. will do;
⑦ 在时间/条件状语从句中，如果从句用一般现在时，主句用将来时；⑧ another day 比较 be going to 与 will:
be going to 表示近期、眼下就要发生的事情，will 表示的将来时间则较远一些。 如：He is going to write a letter tonight. He will
write a book one day.
2. be going to 表示根据主观判断将来肯定发生的事情，will
表示客观上将来势必发生的事情。
He is seriously ill. He is going to die. He
will be twenty years old.
3. be going to 含有“计划，准备”的意思，而 will 则没有这个意思，如：
She is going to lend us her book. He will be
here in half an hour.
4. 在有条件从句的主句中，一般不用 be going to, 而多用 will。如：
If any beasts comes at you, I'll stay with you and help you.
掌握了它们的这些不同，你就能很好的区分 be going to 与 will 了。
一般将来时常见的标志词
① 含 tomorrow; next 短语； ② in + 段时间 ;
③ how soon; ④ by + 将来时间；
5. 祈使句句型中：or/ and sb. will do
例：Be quick, or you will be late = If you don't be quick, you will be late
