◆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， Ill think of my old friend.
②If you do that， I shall be very pleased.
③Theyll stand by you even if you dont 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， Well have a meeting here tomorrow morning.
Bob said (that) they would have a meeting there the next morning.
◆定语从句中关系代词只能用that和不能用that的几种情况：
只能用that的情况
1. 先行词是不定代词。
例句：Please tell me everything that happened to you.
2. 先行词被形容词级、序数词或only， last， same， very等修饰。
例句： ①This is the most interesting movie that I have ever seen.
②This is the only book that I read during the summer holiday.
3. 先行词既包括人又包括物。例句：She talked about the writer and his works that interested her.
