...小学英语语法:小升初英语语法复习 动词的语态
12. 动词的语态
语态有两种:主动语态和被动语态。
主语是动作的发出者为主动语态;主语是动作的接受者为被动语态。
1)若宾语补足语是不带to 的不定式,变为被动语态时,该不定式前要加"to"。此类动词为感官动词。
feel, hear, help, listen to, look at, mak英语e, observe, see, notice, watch
The teacher made me go out of the classroom.
--> I was made to go out of the classroom (by the teacher).
We saw him play football on the playground.
--> He was seen to play football on the playground.
2)情态动词+ be +过去分词,构成被动语态。
Coal can be used to produce electricity for agriculture and industry.
12.1 let 的用法
1)当let后只有一个单音节动词,变被动语态时,可用不带to 的不定式。
They let the strange go.---> The strange was let go.
2) 若let 后宾补较长时,let 通常不用被动语态,而用allow或permit 代替。
The nurse let me go to see my classmate in the hospital.
----> I was allowed / permitted to see my classmate in the hospital.
12.2 短语动词的被动语态
短语动词是一个整体,不可丢掉后面的介词或副词。
This is a photo of the power station that has been set up in my hometown.
My sister will be taken care of by Grandma.
Such a thing has never been heard of before..

高考英语语法:高中英语语法-写好英语作文的几个途径
写好英语作文的几个途径
要想写好英语作文,提高写作水平,笔者认为应从以下几个方面着手。
一、广泛阅读,认真模仿
写作是一个用语言表达思想的实践过程,写一篇文章会涉及到很多知识,如词汇、句法等。写作是一种输出行为。如果没有足够的输入,要想输出好的文章是很难的。只有往脑海里输进了大量的词汇、句型和各种语法知识,才能写出好的文章。因此,阅读对写作起着至关重要的作用。
在阅读时,应该把一些精妙的东西抄录下来,如一些好的词组、句型,并经常翻看,把收集到的短语及句型转化为自己写作时可用的材料。用学过的短语进行造句,并举一反三,用不同的单词或句子表达同一思想或同一含义,使写出来的文章更有风采,更加生动。
如在介绍自己的爱好时,可以说: I like … , I'm interested in … , I'm fond of … , I'm crazy about … , I take pleasure in …等。
总之,熟记和背诵一些精彩的句子或段落,这样做,既可以模仿句型,又可以培养英语语感,从而提高写作水平。
二、换句型,变结构,进行多样化训练
英语中有倒装句、强调句、非谓语动词和各种从句等。这些都可以用到写作中来,通过不同句式的交叉使用,增加句子的层次感和节奏感,使句子灵活、简洁、富于表现力。写作时可以使用下列手段,使句子更加生动简洁。
1. 复合结构。例如:
( 1 ) With all the lights on, the street looks more beautiful.
( 2 ) With all the students looking at her, the girl didn't dare to answer the question.
2. 从句。
通过使用定语从句、名词性从句和状语从句等使表达更加确切,丰富。例如:
( 1 ) This is the place where I used to work with the peasants.
( 2 ) Soon the news came that our football team had won.
3. 分词短语。
在写作中,对句子的状语部分,学生们习惯于用状语从句,其实用分词短语会使句子更加简练。例如:
( 1 ) Laughing and talking, the students went out of the classroom.
( 2 ) Given more water, the trees would have grown better.
4. 倒装句和强调句。例如:
( 1 ) Only then did Tom know his mistakes.
( 2 ) It was at ten o'clock that it began to rain.
5. 用副词或动词不定式短语作句子开头。...

Mr. Smith is still in bed. 史密斯先生还在睡觉。

a woman in black 一个穿黑衣的妇女
a book on sports 一本关于运动的书
a boy with red hair 红头发的男孩
a bird in the tree 树上的鸟
4. 介词短语可以用作宾语补足语。如:

The cold kept him in bed for three days. 这次感冒让他卧床三天。
用作宾语补足语的介词短语在相应的被动语态中则为主语补足语:
