can和could
can的主要用法是：
1. 表示能力： eg. The girl can dance very well.
2. 表示说话者的推测﹑事物的可能性: eg. Can the news be true?
should 用法
1. 应该=ought to （劝告、建议） You should study hard. You should read his new book.
2. 表估计，可译为“按理应当”、“估计”。 Try phoning Robert, he should be home
now.
should 用法 3. 用于第一人称，询问意愿，语气温和委婉
can(could)和be able to都可以表示能力，意思 上没有区别。但can只有现在式和过去式， 而be able to则有更多的形式。如：
Those bags look really heavy, are you sure you’ll be able to carry them on your own?
