顺口溜:本领最多不定式,主表定补宾和状
;样样成分都能干,只有谓语它不敢;大家千万要小
心,有时它把句型改;作主语时用it,自己在后把
身藏;七个感官三使役,宾补要把to甩开;
疑问词后接上它,宾语从句可充当;逻辑主语不定式,不定
式前加for sb.;to前not是否定,
各种用法区别开。

八年级上英语语法点滴
1.
用于表示“应该”或“不应该”的概念。此时常指长辈教导或责备晚辈。例如:
you should
be here with clean hands. 你应该把手洗干净了再来。
2.
用于提出意见劝导别人。例如:
you should go to the doctor if
you feel ill. 如果你感觉不舒服,你最好去看医生。
3.
用于表示可能性。should的这一用法是考试中常常出现的考点之一。例如:
3)
what...? 与 which...?
1. what 与 which
都是疑问代词,都可以指人或事物,但是what仅用来询问职业。如:
what is your
father? 你父亲是干什么的?
该句相当于:
what does your
father do?
what is your father's job?
which 指代的是特定范围内的某一个人。如:
---which is peter?
哪个是皮特?
---the boy behind mary. 玛丽背后的那个男孩。
2. what...?是泛指,所指的事物没有范围的限制;而
which...?是特指,所指的事物有范围的
限制。
which color do
you like best, blue, green or yellow? (有特定的范围)
你最喜爱哪一种颜色?
3. what 与 which
后都可以接单、复数名词和不可数名词。
4) 频度副词的位置
1.常见的频度副词有以下这些:
always(总是,一直)
usually(通常)
often(常常,经常)
sometimes(有时候)
never(从不)
2.频度副词的位置:
a.放在连系动词、助动词或情态动词后面。如:
b.放在行为动词前。
c.有些频度副词可放在句首或句尾,用来表示强调。如:
sometimes i
walk home, sometime i rides a bike.
有时我步行回家,有时我骑自行车。
放在句首时,主语、谓语动词要倒装。如:
1. every day 作状语,译为“每一天”。如:
we go to
school at 7:10 every day.
我们每天7:10去上学。
i
decide to read english every day.
我决定每天读英语。
2. everyday 作定语,译为“日常的”。
6) 什么是助动词
1.协助主要动词构成谓语动词词组的词叫助动词(auxiliary
verb)。被协助的动词称作主要动
词(main verb)。
助动词自身没有词义,不可单独使用,例如:
he doesn't like
english. 他不喜欢英语。
(doesn't是助动词,无词义;like是主要动词,有词义)
2.助动词协助主要动词完成以下功用,可以用来:
a. 表示时态,例如:
he
is singing. 他在唱歌。
he has got married. 他已结婚。
b. 表示语态, c. 构成疑问句,例如:
do you like college
life? 你喜欢大学生活吗?
did you study english before
you came here?你来这儿之前学过英语吗?
d.
与否定副词not合用,构成否定句,例如:
i don't like him. 我不喜欢他。
e. 加强语气,例如:
do come to the party tomorrow
evening. 明天晚上一定来参加晚会。
he did know that.
他的确知道那件事。
3.最常用的助动词有:be, have, do, shall,
will, should, would
7) forget doingto
do与remember doingto do
to do 忘记要去做某事。 (未做)
forget doing 忘记做过某事。 (已做)
the light
in the office is still on. he forgot to turn it
off.
办公室的灯还在亮着,它忘记关了。(没有做关灯的动作)
he forgot
turning the light off.
他忘记他已经关了灯了。 ( 已做过关灯的动作)
don't forget to come tomorrow.
别忘了明天来。 (to
come动作未做)
典型例题
---- the light in the
office is still on.
---- oh,i forgot___.
a. turning it off b. turn it off
c. to
turn it off d. having turned it off
答案:c。由the
light is still on 可知灯亮着,即关灯的动作没有发生,因此用forget to do
sth.
而forget doing sth
表示灯已经关上了,而自己忘记了这一事实。此处不符合题意。
er to do 记得去做某事
(未做)
remember doing 记得做过某事 (已做)
8) it's
for sb.和 it's of sb.
与不定冠词a、an连用,结构为“such+aan+形容词+

12) 英语中的“单数”
1.主语的第三人称单数形式,即可用“he, she, it”代替的。如:
he,
she, it
my friend, his teacher, our classroom,
tom, mary's uncle
2.名词有单数名词和复数名词。如:
man(单数)---men(复数)
banana(单数)---bananas(复数)
5.表示“某国人”的单、复数变化。即“中日瑞不变英法变,其它国把-s加后面”。如:
chinese---chinese japanese---japanese
swiss---swiss
englishman---englishmen
frenchman---frenchmen
american---americans
australian---australians
canadian---canadians
korean---koreans
russian---russians indian---
indians
6.其它。如:
14) 双写最后一个字母的-ing分词
15) 肯定句变否定句及疑问句要变化的一些词
变为any。
但是,若在表示请邀请、请求的句子中,some可以不变。如:
would you
like some orange juice?
与此相关的一些不定代词如something,
somebody等也要进行相应变化。
3.注意区分以下的in的用法。
i'll
visit him in a week.
一周后我会去拜访他。

2)动词+不定式 ;动词+宾语+不定式
ask, beg, choose,
expect , hate, help intend like, love, need wants
to believe
anything but to take the medicine.
11)当两个或多个不定时短语由连词and,but或or连接时,后一个或几个不定式符号to常<
br>省略。但若表示对比、对照关系时,则不能省略。
he wants to move to
france and marry the girl.
the purpose of new
technologies is to make life easier,not to make it
more difficult.
12)不定式做表语时,一般要带to,但若主语部分中含有do的各种形式时,符号to可省去。
we've missed the last we could do now is walk
home.
动词不定式的否定式
tell him not to shut the
window…
she pretended not to see me when i
passed by. 我走过的时候,她假装没看见。
不定式的特殊句型
1、不定式的特殊句型so as to
1) 表示目的;它的否定式是so as not
to do。
tom kept quiet about the accident so as
not to lose his job.
汤姆对事故保持沉默是为了不丢掉他的工作。
go in quietly so as not to wake the baby.
轻点进去,别惊醒了婴儿。
2) so kind as to ---劳驾

2、 动词原形表达向某人提出建议

例如:

holiday?
干吗不去度假?
3、it's for sb.和 it's of
sb.
1)for sb. 常用于表示事物的特征特点,表示客观形式的形容词,如easy,
hard, difficult,
interesting, impossible等:
it's very hard for him to study two languages.
对他来说学两门外语是很难的。
2)of
sb的句型一般用表示人物的性格,品德,表示主观感情或态度的形容词,如good, kind,
nice, clever, foolish, right。
it's very
nice of you to help me. 你来帮助我,你真是太好了。
for 与of
的辨别方法:
用介词后面的代词作主语,用介词前边的形容词作表语,造个句子。如果道理上通顺用o
f,不
通则用for。如:
you are nice. (通顺,所以应用of)。
he is hard. (人是困难的,不通,因此应用for。)
4、不定式的特殊句型too…to…
1)too…to 太…以至于…
he
is too excited to speak.
他太激动了,说不出话来。
---- can i help you ? 需要我帮忙吗?
---- well,
i'm afraid the box is too heavy for you to carry
it, but thank you all the
same.
不用了。这箱子太重,恐怕你搬不动。谢谢您。
2)
如在too前有否定词,则整个句子用否定词表达肯定, too 后那个词表达一种委婉含义,
意
为不太。
it's never too late to mend. (谚语)
改过不嫌晚。
3) 当too 前面有only, all, but时,意思是:非常…
等于very。
i'm only too pleased to be able to
help you. 我非常高兴能帮助你。
he was but too eager to
get home. 他非常想回家。动词不定式的与介词的区别 to
有两种用法:
一为不定式+动词原形;
一为介词+名词动名词, to
在下面的用法中是第二种,即to+ 名词动名词:
admit to承认,confess
to承认,be accustomed to 习惯于,be used to 习惯于, stick
to 坚持, turn to开始,着手于, devote oneself to 献身于,
be devoted to 致力于, look
forward to 盼望,pay
attention to 注意
介词but,except,besides+to do(do)
在这种句型中,如介词前有动词do,后面应接不带to的不定式;如无do,则接to不定式,即带do不带to, 带to不带do。如:
the enemy soldiers had
no choice but to give in.
on sunday afternoon
i had nothing to do but watch tv.
动词不定式与动名词区别与联系
1) 动名词与不定式的区别:
动名词表达的是:
状态,性质,心境,抽象,经常性,已发生的 不定式表达的是:
目的,结
果,原因,具体,一次性,将发生的
2) 接不定式或动名词,意义相同。
3)在下列情况下,一般要用不定式:
①hate,like,love前有would(should)时,如:i'd like to
have a cup of coffee.
②当谓语动词begin,continue,start等是进行式时,如:thestudents
are starting to work
on the di fficult maths
problem.
③begin,continue,start与know,understand
等状态动词连用时,如:i soon began to
understand what was
happening.
⒋advise,allow,encourage,forbid,perm
it等动词后接动名词作宾语,或带不定式作宾语补足
语。如:
our teachers
don't permit ourus swimming in the lake.
our
teachers don't permit us to swim in the lake.
4) 部分动词后接不定式或动名词时,意义差别较大,应根据句子语境选择使用。
①for
get,remember,regret后接不定式,表示现在或未来的动作,接动名词表示动作已经发
生。如:
don't forget fo post the letter for me.
have you forgotten meeting her in beijing
airport?
remember to close the windows before
you leave.
i remember writing him a letter a
year ago.
we regret to tell you that
all of you are not invited toattend the meeting.
