四：.情态动词用法归纳
情态动词有can (could), may (might), must, have to, shall (should, will (would), dare (dared), need (needed), ought to等。情态动词无人称和数的变化；不能单独使用，必须与其后的动词原形构成谓语
一、can, could
1) 表示能力（体力、知识、技能）。
Can you lift this heavy box?（体力）
Mary can speak three languages.（知识）
Can you skate?（技能）
此时可用be able to代替。Can只有一般现在时和一般过去式而be able to则有更多的时态。
I’ll not be able to come this afternoon.
当表示“经过努力才得以做成功某事”时应用be able to，不能用Can。如：
He was able to go to the party yesterday evening in spite of the heavy rain.
2) 表示请求和允许。
-----Can I go now?
----- Yes, you can. / No, you can’t.
此时可与may互换。在疑问句中还可用could,
might代替，不是过去式，只是语气更委婉，不能用于肯定句和答语中。
---- Could I come to see you tomorrow?
---- Yes, you can. (No, I’m afraid not. )
3) 表示客观可能性（客观原因形成的能力）。
They’ve changed the timetable, so we can go by bus instead.
This hall can hold 500 people at least.
4) 表示推测（惊讶、怀疑、不相信的态度），用于疑问句、否定句和感叹句中。
Can this be true?
This can’t be done by him.
How can this be true?
二、may, might
1) 表示请求和允许。might比may语气更委婉，而不是过去式。否定回答时可用can’t
或mustn’t，表示“不可以，禁止”。
----Might/ May I smoke in this room?
---- No, you mustn’t.
---- May/Might I take this book out of the room?
---- Yes, you can. (No, you can’t / mustn’t. )
用May I...？征徇对方许可时比较正式和客气，而用Can I...？在口语中更常见。
2）用于祈使句，表示祝愿。
May you succeed!
3) 表示推测、可能性（不用于疑问句）。
might不是过去式，它所表示的可能性比may小。
1．He may /might be very busy now.
2．Your mother may /might not know the truth.
三、must, have to
1) 表示必须、必要。
You must come in time.
在回答引出的问句时，如果是否定的，不能用mustn’t（禁止，不准），而用needn’t, don’t have to（不必）. ---- Must we hand in our exercise books today?
---- Yes, you must.
---- No, you don’t have to / you needn’t.
2) must是说话人的主观看法，而have to则强调客观需要。Must只有一般现在时，have to有更多的时态形式。
1．he play isn’t interesting, I really must go now.
2．I had to work when I was your age.
3) 表示推测、可能性（只用于肯定的陈述句）
1．You’re Tom’s good friend, so you must know what he likes best.
2．Your mother must be waiting for you now.

1) dare作情态动词用时, 常用于疑问句、否定句和条件从句中, 过去式形式为dared。

2．He daren’t speak English before such a crowd, dare he?
3．If we dared not go there that day，we couldn’t get the beautiful flowers.
2) need 作情态动词用时, 常用于疑问句、否定句。在肯定句中一般用must, have to, ought to, should代替。
1．You needn’t come so early.
2. ---- Need I finish the work today?
---- Yes, you must. / No, you needn’t.
3) dare和need作实义动词用时，有人称、时态和数的变化。在肯定句中，dare后面常接带to的不定式。在疑问句和否定句中，dare后面可接带to或不带to的不定式。而need后面只能接带to的不定式。
1. I dare to swim across this river.
2. He doesn’t dare (to) answer.
3. He needs to finish his homework today.
五、shall, should
1) shall 用于第一人称，征求对方的意见。

Will / Would you pass me the ball, please?
2) 表示意志、愿望和决心。
1. I will never do that again.
2. They asked him if he would go abroad.
3) would表示过去反复发生的动作或某种倾向。would表示过去习惯时比used to正式，且没有“现已无此习惯”的含义。

How do you feel when you have to make a speech in front of class? What about when you go to a birthday party? Do you get really shy?
①害羞是指你在其他人周围时感到紧张和害怕. Experts have found that more than 80 percent of middle school students feel afraid to be the center of attention. Some kids are born shy. ③有的后来变得害羞因为生活经历
It’s OK if it takes you a while to feel yourself again when you go to a new place or meet new people. In fact, everybody gets a little shy sometimes. It’s just a case of how much.
Most people have red faces and talk in broken sentences when they get shy. But ②some become so shy that they won’t go to a restaurant because they are too nervous to order and pay for their food. Some are afraid of meeting new people, so they seldom go outside. This kind of shyness can be bad for a person.
If shyness doesn’t stop you from doing something you want to do, being shy isn’t a very big problem. Some experts say ④害羞的人比较聪明因为他们想得多讲得少。. Shy people are also good at working with others because they think more for other people. Some great people in history were shy, too.
You see, being shy isn’t all bad. But remember not to let good opportunities(机会) pass by just because of it! If you have to sing a song at a birthday party or practice your spoken English in front of others, just do it! There’s
nothing to be afraid of.

Australia has a lot of lovely animals. You cannot find them anywhere else in the world. The most famous ones are kangaroos and koalas(树袋熊).
The kangaroo is the symbol of Australia. They have large eyes and ears. They don’t walk, they jump. They use their strong back legs. ①袋鼠每小时能跳多达74千米They can go over nine metres in one jump!
Kangaroo mothers have pouches(育儿袋) to carry their babies. The babies stay inside to get milk and keep warm.
Kangaroos are everywhere in Australia. They are on TV, in books and in the shops. ②The government even wants to put them on passports(护照).
There are about 20 to 25 million kangaroos in Australia. That’s more than the number of people in the country!
③一些袋鼠挨饿因为没有足够的食物吃They break into farms for food. Farmers are very angry with them.
The koala is another famous Australian animal. They look like bears, and have small eyes and big noses. They eat leaves from eucalyptus(桉树), where they spend most of their time.
Koalas have a special smell. They use it to mark their home—“This is my place, you can’t come in!”
像袋鼠一样，小树袋熊住在它妈妈的育儿袋里。
But koalas have fewer places to live in. There are about 100,000 koalas in Australia. There is a law to keep them safe.

【教学案例分析】 换位看问题，课堂更精彩 根据学校教学活动安排，我们化学组进行轮流听课，今天由我上一堂公开课。为体现新课程理念，在备课时，经过仔细考虑，决定《燃烧和灭火》一课由实验导入，这样学生的情绪一下就会被调动起来，课堂气氛也很活跃。 我满怀信心地做起了实验，首先在烧杯中倒入热水，然后在铜片两端放上红磷、白磷，一会儿，白磷燃烧起来了，生成了大量白烟，同学们很惊讶，为什么白磷燃烧而红磷不燃烧呢？经过大家一番热烈的讨论，同学们的回答比我预想的还要精彩。俗话说：良好的开端等于成功的一半。我心中不免一阵暗喜。正当我准备做下一个实验时，平时不太“安分”的xx小声的嘟了一句“老师前面教育我们要保护环境，自己却在放烟雾弹……”没有等他说完，他的话被我严厉的目光打断了。当时心想公开课上可不能出“意外”，没有再理会，便按部就班地做下去了。 下课后，我找到他，批评道：“公开课上，你也敢和老师抬杠，唱对台戏，想呈英雄啊！”紧接着他说：“没有啊，这样做是不好啊！”他一脸的委屈。“老师是按教材要求去做的，那你说说，该怎么做？”“敞口燃烧还不如放入密闭容器中燃烧，教室里就不会浓烟滚滚啦！”多么精彩的想法啊！“看来老师批评错了，对不起！老师向你道歉。”当时我的心情久久不能平静。以前我总是强调教材的权威、教师的权威，高高地站在讲台上，没有蹲下来（不是指肢体的蹲下而是心灵的蹲下）和同学们对话，没有耐心倾听学生的发言！
由此想来，作为教师应善于从学生的角度思考和看待问题，努力把握学生心理的真实想法，积极的与学生进行沟通，蹲下来倾听学生的声音，我们的课堂教学或许更真实、更精彩！经过这次风波以后，我发现高翔同学上课听讲比以前认真多了，回答问题也特别积极，成绩也直线上升了。事实上，越来越多的实践证明，学生在观察、思考、选择和体验等方面都和成人之间有着很大的差异，甚至在某些时候，他们比成人视野更开阔，思维更独特，对问题常常有出人意料的看 法和思考。此时，教师如果仅仅用自己传统的眼光来看待学生，往往是很难取得预期的效果，被学生“抬杠”也就在所难免了。我们该给每一个学生平等的机会，让学生对自己的见解能畅所欲言，或许精彩就在你的仔细聆听中产生！
九年级英语教学案例 一、背景分析： 1、教材分析 这部分内容是在学生掌握了一些基本语法知识的基础上，充分利用学生熟悉的生活对话来激发他们的求知欲望，通过直接引语和间接引语的转化，进而复习宾语从句的用法，这部分内容安排了内容丰富、形式多样的小组活动，让学生去总结理解，培养学生的合作与自主学习的水平。 2、以往教法分析 在绝绝大部分教师的学案中，几乎都会出现“学习目标”、“重点”“难点”等环节，学生看后绝绝大部分都感到茫茫然，不知道怎么去掌握。教学中不能没有“学习目标”、“重点”“难点”，我认为这是老师在教学过程中需要重点把握的东西，是应该体现在教案中的东西。 3、学情分析 学生通过前面的学习已初步了解了直接引语，间接引语，宾语从句的基本概念，，也掌握了基本的知识。但是不能灵活使用，知识不系统，综合应用水平差，学生在掌握这部分知识的过程当中总是感到有些地方不好理解、不好把握。 二、教学方案设计： 我针对上述现象，主要从这几方面实行了优化。 ⒈学案设计上，去掉了“学习目标”、“重点”“难点”等环节，取而代之的是“个人难点整理”，要求学生在自己思考、相互讨论交流之后把自己在平时做题当中认为还不是很明白、不理解的地方写在下面，下课后再认真对照一遍，看看是不是又有进步了。我认为学生自己认为不懂，听老师讲后又懂了的东西才是重、难点，才是需要老师重点对待的。 2、为了活跃气氛，我在教学过程中，设计了对话练习，学生小组合作学习的复习方案，这样所有同学都会融入思考中，基础差点的有组长的积极协助，课堂气氛异常活跃，在不知不觉中，把难理解的知识简单化了，同时还增强了解题讲述水平；从而轻松愉快地实现知识复习与水平的提升。 导学案设计： （一）学习目标： 1．复习本单元所学的单词和短语。 2．复习掌握所学的时态。 3．直接引语和间接引语的灵活使用，学会陈述别人所说的话。 （二）知识回顾与检测： Do these exercises by yourself , then discuss into groups . Try to say answers and reasons . 1. I ________ ( live ) in Beijing in 199 2. 2. We _____ ( go ) to Marcia’s house on Friday night . 3. We ______( go ) to the beach every Saturday . 4. lana ______ ( go ) to the beach every Saturday .
