8.will + have + 过去分词结构
1）表示过去将来时态，表示将来某个时刻已完成的动作。
When you come at eight this evening I will have corrected all the papers.
当你今晚八点来到时我将批改好所有的试卷。
2）will作情态动词用，作“一定会”；“想必”解。有时表示猜测。
We will have done the job ahead of time if it doesn’t rain.
如果不下雨，我们定能提高完成这项工作。
9.see sb. do sth./ see sb. doing sth
前者表示“看见某人做了某事”，后者表示“看见某人正在做某事”。
比较： see sb. do sth. 在see用于被动语态形式时要写成be seen to do sth., 注意一个带to, 一个不 带to。
see sth. doing sth. 改为被动形式时doing不变。
The boy was seen to fall from the horse.
Smoke was seen rising from the chimney.
其它感觉动词observe, notice, hear, look at, listen to 等等都有同样的结构和区别
语法：直接引语和间接引语 1）普通陈述句由直接引语变间接引语时需注意人称代词的变化、时态的变化以及某些动词和时间、地点状语的变化。人称代词的变化需根据具体的语境而定。动词时态的变化一般向前推进一个时态，如现在时要改为过去时、过去时改为过去完成时等。某些动词、时间和地点状语的变化可参见下表。
注意人称代词，动词时态，动词，时间及地点状语的变化：
如果时间状语为具体的某年某月某日，在变为间接引语时保留，其相应的时态可以保留不变，有的时态仍需变化，视上下文而定。如：
2）如果说直接引语为疑问句，变为间接引语时，除了作出上表所要求的变化外还要将疑问语序改为陈述语序，就像一般宾语从句的语序一样。如果是一般疑问句需加if 或whether表示“是否”。如：
3)如果直接引语为祈使句，在变换为间接引语时除了作出上表所要求的变化以外有时还需变换动词。
