　　在實(shí)際應(yīng)用中，時(shí)態(tài)的基本規(guī)律并不復(fù)雜，只要多想多用，很快就可以掌握的，至于更多的變化，也完全可以在以后的學(xué)習(xí)中逐步掌握的。而能用之后我們又會(huì)發(fā)現(xiàn)，其實(shí)每篇文章里時(shí)態(tài)的搭配都可以有多種方案，就像我們每個(gè)人的衣著可以有很多種搭配一樣，我們時(shí)態(tài)的用法也可以有多種搭配方案，只要能符合表現(xiàn)文章的主題的需要，就應(yīng)該說(shuō)是正確的。至于哪種是最佳的方案，則各人有個(gè)人的看法，所謂仁者見(jiàn)仁，智者見(jiàn)智了。
