语法讲解
情态动词
情态动词表示说话人的某种语气或情绪,如可能、意愿、猜测、义务、需要等。
情态动词有一定的词义,但不能单独作谓语,后面接动词原形;没有人称和数的变化(be able to,have to除外);有些情态动词有过去式,如:can-could,may-might,will-would,dare-dared,have to-had to等。
1. be able to be able to
后接动词原形,表示某人做某事的能力,可用于大多数时态。用于过去时态时,还可表示“某人过去或当时成功地做了某事”。
I will be able to speak German in another two months.
再过两个月我就能说德语了。
I haven't been able to read that report yet.我还没能看那份报告。
They were able to escape from the building when the fire broke out.火灾发生时,他们设法从大楼里逃了出来。
【用法辨析】can与be able to
(1)can与be able to都表示能力,在许多情况下可以交替使用。
但can只有现在式和过去式(could),而be able to则有更多的形式。
(2)can一般指自身具有的能力,而如果要表达将来的能力,一般要用will be able to
(3)be able to的过去式was/were able to在肯定句中可表示过去设法做成了某事,相当于managed to do,而could则无此意义。
2. dare
dare意为“胆敢,敢于",既可作情态动词,又可作实义动词。
(1)dare作情态动词时,没有人称和数的变化,但有过去式dared,后接动词原形,否定式为dare not/daren't, 多用于否定句或疑问句。
I am so afraid that I dare not move.我害怕得不敢动。
Dare you tell her the truth?你敢告诉她真相吗?
She dared not breathe a word of it to anybody.她对任何人都只字不提此事
(2)dare作实义动词时,有时态、人称和数的变化,后接带to的不定式,否定式要在其前加don't/doesn't/didn'to不定武符号to有时可以省略。
I am so afraid that I don't dare to move.我害怕得不敢动。
Do you dare to fight him?你敢和他对抗吗?
He didn't dare(to)say what he thought.他不敢说出他的想法。
【学法点拨】
情态动词dare可用于以下结构:I dare say...我想/我认为……
How dare you...你怎么敢……?
I dare say he will fail.我认为他会失败。
How dare you say such a thing?你怎么敢说这样的话?
3. have to
have to表示“必须,不得不”,是由于客观情况而必须,have to的否定形式don't have to表示“不必”,可用于各种时态中。
They had to put off the sports meeting because of the bad weather由于天气不好,他们不得不推迟运动会。
You don't have to knock-just walk in.不必敲门进来就是了。
【用法辨析】have to与must
have to must
强调客观需要 强调主观看法
有多种时态形式 只有一种形式
否定形式表示“不必” 否定形式表示“禁止”
I have to learn another language.
我不得不学另一种语言。(客观情况使得)
I must learn another language.我必须学另一种语言。(说话人的意愿)
You don't have to tell others.你不必告诉别人。
You mustn't tell others.你不准告诉别人。
4 had better
had better意为“最好”,主要用来表示劝告或建议。用于一般现在时或一般将来时,适用于所有人称,否定式为had better no。
had better do sth.最好做某事
had better not do sth.最好不要做某事
We had better call in a specialist at this critical moment.
在这个关键时刻我们最好请一位专家来。
You had better not do that.你最好不要那样做。
We'd better not just talk and let's help them.我们最好不要光说不做,让我们来帮助他们。
5 need
need意为“需要,有必要”,既可作情态动词,又可作实义动词。
(1)need作情态动词时,没有人称和数的变化,后接动词原形,常用于否定句或疑问句中,否定式为need not/needn't,意为“不必”。
needn't have done表示实际上做了本来不必做的事,意为“本来不必”。
You needn't finish that work today.你不必今天做完这项工作。
Need I pay the whole amount now?我必须现在全部付清吗?
You needn't have worried about the dinner—it was delicious!你原本不必为这顿饭担心的-味道棒极了!
【误区警示】
①以need开头的疑问句,否定回答可用needn't,肯定回答用must.
②以must开头的一般疑问句,肯定回答用must,否定回答用needn't或don't have to.
(2)need作实义动词时,有人称和数的变化,后接名词、代词、动名词、带to的不定式,用于陈述句、否定句或疑问句中均可,否定式和疑问式要借助助动词do/does/did need作实义动词时常用于下列句式:
sb. need(s)to do sth.某人需要做某事(主语与do为主动关系)
sth. need(s)doing/to be done某事/某物需要被(主语与do为被动关系)

写作技巧
1.写作指导
普通英文邀请信邀请的对象一般是朋友、熟人,所以内容格式上的要求都比较松,可以写得随便一些。表明邀请的意图,说明活动的内容、时间、地点等。但既然是邀请信,那么就一定要在信中表达非常希望对方能够参加或者出席的愿望。正式英文邀请信一般由会议或学术活动的组委会的某一个负责人来写,以组委会的名义发出,而且被邀请者通常也是属于比较有威望的人士。因此,这类邀请信的措辞要相对正式一些,语气要热情有礼。
(1)格式:英语的书信通常包括heading(信头,包括寄信人地址和寄信日期),greeting(称呼),body(正文),ending(结束语)和signature(签名)五个部分。公务信函中还应该包括inside address(信内地址,即收信人地址)。
高考对书信的格式不做要求,因此,写好正文部分是重点。
(2)文章结构:一般采用三段式结构。
第一段:表明写作意图。
第二段:主体部分,说明活动的内容、时间、地点等。第三段:结尾,表达希望对方能够参加或者出席的愿望。
(3)人称、时态:第一、二人称;一般现在时和将来时为主。
(4)文体:书信体。
2. 增分表达
(1)开头常用语
① We're throwing a surprise party for...We'd like to invite you to...It's my honor to invite you to...
我们将为…举办惊喜派对。我们想邀请你…非
常荣幸地邀请你

Some chefs will demonstrate their superb cooking skills of making different kinds of delicious and satisfying noodles and visitors are recommended to taste them for free. I think it is such a good chance for you to experience Chinese culture that you will not resist it. It is convenient for us to get there by bus or walk there.
Looking forward to your coming here soon!
