◆动词时态应注意的几点
1.瞬间性动词的一般现在时和现在进行时常用来表示将来的动作。例句：
①The film begins in a minute.
②My uncle is leaving tomorrow morning.
2.在时间、条件、让步状语从句中,常用一般现在时代替一般将来时。例句：
①Every time I listen to that song, I’ll think of my old friend.
②If you do that, I shall be very pleased.
③They’ll stand by you even if you don’t succeed.
3.一般过去时和现在完成时的区别：一般过去时和现在完成时都表示过去所发生的动作，但现在完成时强调这一动作与现在的关系，如对现在产生的影响、结果等，所以它不能和表示过去的时间状语连用;一般过去时只表示过去的事实，不表示和现在的关系,因而它可以和表示过去的时间状语连用。如：
—Have you finished your work?
—Yes, I have.
—When did you finish it?
—I finished it last summer.
◆直接引语与间接引语转换时应注意的几个问题：
1.人称的变化
2.时态的变化
3.时间状语的变化
4.地点状语的变化
例句：
①Xiao Yi said, “I want to go to the park this afternoon.”
→Xiao Yi said (that) he wanted to go to the park that afternoon.
②Bob said, “We’ll have a meeting here tomorrow morning.”
→Bob said (that) they would have a meeting there the next morning.
