Skimming意为“快速掠过，从中提取最容易取得的精华”。这种读法包含有原词的所有意思——快速读过去，取出读物中关键性的东西。
因此，我们可以把这种读法理解为快速浏览课文，领会文章大意。一般而言，通过标题可知道文章的主题。对文章的首段和末段要多加注意，每一段的主题句也十分关键，以便发现作者的观点。Dear Sir or Madam,
I think/believe that _______________________.

Yours truly,
__________PatternDear Sir or Madam,
I believe that children should do some chores at home. I disagree that children's only job is to study hard and do well at school.
However, I think it is unfair for children to expect their parents to work hard outside and do all the household chores, too. I think children should at least do some simple chores to help their busy
parents.Model For example, they should make their own beds and clean their own rooms because they are the ones who use these. They may not have time to help with the other parts of the house, but they should try to be responsible for their own area. This will help them to grow up to be independent and responsible adults.
Yours truly,

情态动词不能单独做谓语, 除ought和have外, 后面只能接不带to的不定式。情态动词没有非谓语形式，即没有不定式、分词等形式。
情态动词没有人称和数的变化,即情态动词第三人称单数不加-s；但有些情态动词, 如can、will有一般式和过去式的变化。 情态动词不能表示正在发生或已经发生的事情, 只表示期待或估计某事的发生。情态动词的“时态”形式并不是时间区别的主要标志, 不少情况下, 情态动词的现在式和过去式形式都可用来表示现在时间、过去时间和将来时间。◎Summary(1)can & could：could是can的过去式
①can
a. 表示体力或脑力的能力
The girl can dance very well.
b. 表示说话的推测﹑事物的可能性等
Can the news be true?
c. 在口语中, can可以表示请求或允许

you can't.(若关系比较亲近, 也可直接说No, you can't.)a. could是can的过去式，表示与过去有关的能力和推测
We all knew that the young man couldn't be a doctor.
b. could可以代替can表示请求，但语气较can客气和委婉。can 表示一般性的请求，语气随便, 常用于熟人之间或长辈对晚辈、上级对下级的场合。could表示有礼貌的请求，语气委婉，常用于非熟人之间或晚辈对长辈、下级对上级的场合。
Could you lend me your dictionary? can和could接动词的完成形式，表示可能已经做某事。can用在否定和疑问句中, 表示不相信、怀疑等态度。

以could或would提问时，不能再以could或would作答，而应该用can或will。
—Could I borrow your dictionary?
—Yes, of course you can.◎Notice
1. 提出委婉的请求在回答中不可用could。
-Could I have the television on?
-Yes, you can./No, you can't.
2. 在否定、疑问句中表示推测或怀疑用couldn't。
He couldn't be a bad man.他不大可能是坏人。
3. 在表示“请求帮助、请求允许”疑问句中，常用could代替can，表示礼貌、委婉或不确定；而can则不具备这些语气。这时不能把could看作can的过去式。表示请求帮助或请求允许时，除了can, could之外，还可以用may。(2)may & might
表示允许或请求，表示没有把握的推测；may放在句首, 表示祝愿。might表示推测时, 不表示时态，只是可能性比may小。
May God bless you!
He might be at home.
(3)have to & must
两词都是“必须”的意思, have to表示客观的需要，must 表示说话人主观上的看法, 即主观的必要。
My brother was very ill, so I had to call the doctor in the middle of the night.
我弟弟病得很厉害，我只得半夜里把医生请来。
