新概念英语第2册Lesson19~21语法知识点新概念英语第2册Lesson19语法知识点情态助动词can与maycan(过去式为 could)原义为“能”，表示“有能力”、“能够”等：Can you drive a car?你会开车吗?Jim couldn’t run very fast when he was a boy.吉姆小时候不能跑很快。
(1)请求别人允许或答复时一般用 can，could，may和may的过去式 might。
在这4个词中，can最常用，也最不正式;could比can表示更“犹豫”和客气，通常用在不能确定请求是否会得到同意的时候;may 比can和could更正式、更客气、更恭敬;might显得最犹豫，也最客气、最恭敬，但不及上述3个词常用。
实际上，是一般性的请求时，can， could，may往往可以互换。
含有情态助动词的普通答语为：肯定：Of course you can/may.你当然可以。
(不可用could或might)否定：No, you can’t/may not.不，你不可以。
(不用could not或might not)试体会下列例句中这些词的用法:Can I borrow your umbrella(please)?(请问)我能借用你的雨伞吗?Could I borrow your umbrella(please)?(请问)我可以借用一下你的雨伞吗?May I borrow your umbrella(please)?(请问)我可以借用您的雨伞吗?Might I borrow your umbrella(please)?(请问)我是否可以借用您的雨伞?(2)may和might还可以表示可能。
如果说话人对所说事实确信无疑，就可以用be或其他完全动词：Jane is at home now.简现在在家。
(确切的事实)但如果不敢确定，则可以说：Jane may/might be at home.简可能/或许在家。

新概念英语第二册Lesson19~21学习笔记新概念英语第二册Lesson19学习笔记1 The play may begin at any moment.剧马上就要开演了。
在这句话中，说话人指的并不是一种确信不移的事实，而是可能发生的事情，因此用may+动词的结构。
It may have begun already.可能已经开始了。
这句话也是表示可能发生的事情，因为表示可能已经发生的事情，所以用may+动词完成时的结构。
2 hurry to+spl.匆忙赶往某地例句：We hurried to the airport.我们匆忙赶往机场。
3 What a pity!真遗憾!这是What+a/an/the+名词的感叹句形式。
以what开头的感叹句还有以下几种。
①What+名词例句：What fun!真开心!②What+(a/an)+形容词+名词例句：What a said story!真是个凄凉的故事啊!③What+ a/an+形容词+名词(+主语)+谓语例句：What a delicious dinner you made!你做了真丰盛的晚餐啊!④What+名词+主语+谓语例句：What happy girls they are.那些女生好幸福啊!4 exclaim [动词] 惊叫，呼喊相当于scream，cry out，指因疼痛、惊奇、愤怒等突然喊叫。
例句：She screamed when seeing the devastating car accident.当她目击这场惨烈的车祸时忍不住惊叫起来。
词语扩展：exclamation n. 呼喊，惊叫，叹词，感叹语exclamation mark 感叹号，叹号5 Could I ...please?在这句里，could代替了can，这是比较委婉地提出请求的用法。
在时间上和can没有区别。
6 might as well...还是……好，不妨与may as well意思相同，只不过前者更委婉。

《新概念英语》第二册学习笔记20 19课
第20课One man in a boat
1、Fishing is my favorite sport.
fishing 动名词做主语，相当于名词
sport 此句中不是运动，是指娱乐、消遣
2、I often fish for hours without catching anything.
fish 不及物动词，钓鱼
without catching 介词+动名词构成的介词短语
3、Instead of catching fish, they catch old boots and rubbish.
instead of 介词短语，作为......的替换
rubbish 不可数名词，没有复数形式
4、I am even less lucky.
此句省略了比较对象，说全了应该是：I am not even as lucky as they are.
5、You must give up fishing.
give up 放弃后面跟名词
6、They don't realize one important thing.
realize 意识到，另外还有实现的意思
例：He has realized his dream.
7、动名词，由动词+ing组成，语法功能相当于名词，在句子中可以做主语，也可以做宾语。
第19课Sold out
1、The play may begin at any moment.
may 表示可能发生，是一种不确定的猜测
at any moment 马上，随时
2、I hurried to the ticket office.
hurry 不及物动词，匆忙
hurry up 固定词组，赶快，快一点
be in a hurry 匆匆忙忙的，这里hurry 是名词
3、We've sold out.
这句话也可以用票作主语，The tickets are sold out.
sold out 卖完了
sold up 变卖财产
sold ...at 以什么价格出售
sold ...for 卖了多少钱
4、Can I return these two tickets?
return 此句中是退掉的意思
a return ticket 这里return是形容词，往返的
5、They're for next Wednesday's performance.
for 这里表示具体时间，比如：
I have a meeting for two o'clock. 我两点钟有个会。
6、I might as well have them.
may/might as well 不妨怎么样，还是......的好，语气上比be as well 更委婉一些
7、助动词can 和may 都可以用来表示请求，也都可以用来表示推测和表示可能性
文中例句：May I have two tickets please?。
