语态练习
1.被动语态由　 　+　 　 构成。被动语态人称、数和时态的变化由be动词完成:
一般现在时:am/is/are+过去分词
一般过去时:was/were+过去分词
及物动词的过去分词
be
现在进行时:am/is/are being+过去分词
过去进行时:was/were being+过去分词
一般将来时:will be+过去分词
过去将来时:would be+过去分词
现在完成时:have/has been+过去分词
过去完成时:had been+过去分词
◎学法指导:英语动词有两种语态,即主动语态和被动语态。主动语态表示主语是动作的执行者,被动语态表示主语是动作的承受者。
2.英语动词中主动语态用得比较广泛,通常以下两种情况用被动:
(1)强调动作的承受者。
(2)不知道谁是动作的执行者或者没有必要指出动作的执行者。
3.主动语态与被动语态转换

be able to do sth. 表示有做某事的能力,有人称和数的变化,be根据主语要适当变形
can 是情态动词,表示“能、会”,无人称和数的变化

2.I 　 　finish my homework.

from now on的用法 　

●Try your best and work much harder from now on.尽你最大的努力,并且从今以后你要更加努力地去学习。
◎观察思考:from now on 从今以后,从现在开始;from today on从今天起
from then on 从那时起;from that day on从那天起
◎用法总结:from now on和from today on一般用于一般将来时;
from then on 和from that day on用于一般过去时
想一想
含有双宾语结构的句子应怎样变为被动语态
比如:I give him a book.
很简单,强调哪个部分就提前哪个部分,当把直接宾语(物)提前变为被动语态时,要在间接宾语(人)前加相应介词,本句结构应为“sth.be given to sb.”所以此句变被动语态应为:A book is given to him by me.
There be句型 　

●There are more than 3 000 languages spoken in the world.世界上有超过3 000种语言。
◎观察思考:1.There are some people cutting trees.有一些人在砍树。
2.There are some trees cut down by people.有一些树被人砍倒了。
◎用法总结:There be sb.doing sth.意为“有人正在做某事”,表主动;There be sth.done意为“有某事被做了”,表被动。
用所给词的适当形式填空
1.There are some birds 　 　(fly) in the sky.
2.There are some old people 　 　(look after).
flying
looked after
show的用法

●Recent surveys show that more than 500 million people speak English as their mother tongue.最近的研究表明,超过5亿人的母语为英语。
◎观察思考:1.show 表明;说明;告知 show sb.the way to... 　 　
2.show sb.+疑问代词或疑问副词+不定式 　
　
3.show+从句 　 　
告诉某人去……的路
向某人示范……
表明/显示……
现在进行时表将来
●I can't believe that I'm flying to Disneyland.我不敢相信我要乘飞机去迪士尼乐园。
am flying 用现在进行时表示将来时。这种用法所用的动词多是　 　。可用于此种用法表达位移的动词还有go,come,arrive,leave,move,start,meet,begin,stay,return,等。

even if / though和silence的用法 　

●We use body language to communicate how we feel, even if there is silence.即使不说话,我们也能用肢体语言表达感受。
1.even if意为“即使;纵然”,用来引导让步状语从句,可与even though互换使用。如:

whether/if的区别
●Then I know whether she will praise or punish us.那样我就知道她会表扬我们还是惩罚我们。
whether引导宾语从句意为“是否”,相当于if。如:

有些情况下,whether和if的用法有一定区别。
1.whether引导的从句可以与连词or或or not直接连用,而if一般不能。如:

2.whether可以接不定式,if则不能。如:
Tom doesn't know whether to accept or refuse.汤姆不知道是接受还是拒绝。
3.whether引导的从句可以置于介词之后,但if则不能。如:

“特殊疑问词+动词不定式”的用法归纳:
由两部分构成:疑问词和动词不定式(how/wh-+to do)。疑问词部分包括疑问代词who, whom, what, which和whose以及疑问副词when, where和how。 它主要具有以下几种功能:

　.
where to go

1.　 　 the problem is not clear yet.还不清楚要如何处理这个问题。(作主语)
2.The key is 　 　.关键是要选哪一个人。(作表语)
3.I haven't decided 　 　.我还没有决定去哪里。(作宾语)

主从复合句的用法

●Yu Zhen thought studying grammar was important when learning English.余贞认为语法在英语学习中很重要。
这是一个主从复合句。动词thought后接省略了连词that的宾语从句“studying grammar was important when learning English”。when引导时间状语从句。具体成分如下:
Yu Zhen(主语)thought(谓语)studying grammar(宾语从句的主语)was(宾语从句的谓语) important (宾语从句的表语)when(连词)(省略了you are) learning(状语从句的谓语)English(状语从句的宾语)。
as long as和stick to sth./doing sth.的用法 　

●I' m sure that you will make great progress as long as you stick to them.我相信只要你坚持,一定会取得很大进步。
