Unit1 Grammar 同步练习Grammar:句子成分和句子结构一.句子成分句子成分的定义:构成句子的各个部分叫做句子成分。
句子成分有主要成分和次要成分;主要成分有主语和谓语;次要成分有表语、宾语、定语、状语、补足语和同位语。
1. 主语主语是一个句子所叙述的主体,一般位于句首。
但在there be结构、疑问句(当主语不疑问词时)和倒装句中,主语位于谓语、助动词或情态动词后面。
主语可由名词、代词、数词、不定式、动名词、名词化的形容词和主语从句等表示。
指出下列句子中的主语及它的性质:①During the 1990s, American country music has become more and more popular.②often speak English in class.③One-third of the students in this class are girls.④To swim in the river is a great pleasure.⑤Smoking does harm to the health.⑥The rich should help the poor.⑦When we are going to have an English test has not been decided.【答案】①country music (名词)②We (代词)③One-third (数词)④To swim (不定式)⑤Smoking (动名词)⑥The rich (名词化的形容词)⑦When we are going tohave an English test (主语从句)2.谓语谓语说明主语所做的动作或具有的特征和状态。
动词在句中作谓语,一般放在主语之后。
谓语的构成如下:1、简单谓语:由一个动词或动词短语构成。
如:He practices running every morning.2、复合谓语:(1)由情态动词或其他助动词加动词原形构成。
九年级上册英语Unit1 grammar知识讲解和练习-译林版(含答案)
9A Unit1 Know yourself★语法部分学习目标:1. 学会正确使用and, but, or和so连词。
2. 学会正确使用both… and …, not only… but (also) …, either… or…和neither… nor… 关联词语。
在我们过去的英语学习过程中,我们经常碰到and, but, or和so连词,我们能够了解它们在句中的意思,今天我们在此想归纳它们的具体用法。
1. and◇“和”,连接两个名词,代词或两个形容词等语法作用相同的词语。
例如:The air was so warm and bright.It has no eyes and no ears.I have no sister or brother.特别提醒:①and如果用在否定句中,必须把and改成or。
例如:She can’t play badminton or table tennis.He didn’t come or go to see a film with us.②如果前后名词都用no修饰,则可以用and连接。
例如:I have no sister and no brother.◇表示目的,意图。
常用于go, come, stop, run, stay等动词后。
例如:Come and have a rest with us.Stop and see what they’re doing.◇“只要……就会……”“如果……那么……”,用于祈使句后,表示条件与结果的关系。
例如:Knock on the door, and it will be opened.Come l ate again, and you’ll be fired.2. but◇ "但是",“可是”,“而”,“却”的意思,常用作转折连词,表示前后两个内容不一样、不一致。
例如:The old lady can speak, but she can’t write.He is in poor English, but he still keeps working hard on it.特别提醒:①but不与although/though (“虽然,尽管”)连用。
高中英语 Unit1 Grammar课件 牛津译林版必修1
She is an experienced teacher.
二、句 子的种类
1、简单句
(只有一个谓语动词)
2、并列句
(有两个谓语动词以上, 用并列连词连接起来, 他们的地位是平列的)
She is laughing.
主 + 谓(vi)
She opened the door. 主 + 谓(vt) + 宾
that 的特殊用法:
1. 先行词为all everything anything nothing any more one等不定代词(指物) 2. 先行词被all every no some any little much 等词修饰(指物) 3. 先行词被序数词或形容词最高级修饰 或者先行词本身为序数词或最高级。 4. 先行词被the only, the last, the very, the same 等修饰的时候 5. 先行词既有人又有物 6. 主句是以who 或which 等开头的特殊疑问句 7. 关系代词在定于中做表语 8. 先行词为time(次数)和way(方法)时
主谓 一致
1.从句中谓语要注意和先行词保持数和时态上的一致
2. one of …
复数
the (only) one of … 单数
I, who_a_m___ (be) your close friend, will try my best to help you out. He who_d_o_e_s__ (do) not reach the Great Wall is not a true man. Mr. Herpin is one of the foreigners who _a_r_e_ (be) working in China. Mr. smith is the only one of the those foreigners who __is___ (be) working in China.
