语法要点:
一.can、could和may用法
1. 情态动词can 表示现在的能力,could 表示过去的能力,后跟动词原形,can do sth.=is/ am/ are able to do sth. could do sth.= was/ were able to do sth.
不能做某事can/could not do sth.= be not able to do sth.= be unable to do sth.
情态动词could 表示委婉语气,比用can 更加有礼貌,may 比较正式。
一般疑问句回答,通常情况问什么,答什么Can I … Yes, you can. No, you can’t.
请注意下列特殊情况:Could I … Yes, you can. No, you can’t.
May I … Yes, you may. No, you can’t. (坚决拒绝 No, you mustn’t.)
Must I … Yes, you must. No, you needn’t.
表示可能性 may be也许是,(50%) must be一定是,(100%) can’t be 不可能是(0%)。
二.感叹句
1. 用what构成感叹句是,what作名词修饰名词。
1) What + a(n) + 形容词+单数可数名词(+ 主语 + 谓语)!What an exciting game it is!
2) What + 形容词 + 复数名词(+ 主语 + 谓语)!What interesting books they are!
3) What + 形容词 + 不可数名词(+ 主语 + 谓语)!What bad weather it is today!
2. 用How构成感叹句时,How做状语修饰形容词或副词。
How + 形容词/副词 + 主语 + 谓语! How beautiful the dress is!
3. What引起的感叹句都可以转换为how引起的感叹句
1) What good news it is! ---How good the news is!
2) What beautiful flowers they are! ---How beautiful the flowers are!
