第三课 语法篇
1.If引导的真实条件状语从句
1)主将从现(主句一般将来时，从句一般现在时;主句结果，从句条件)
If you ask me a question and I don’t know the answer, I’m gonna tell you
that I don’t know.
如果你问我的问题我不知道，我会直接告诉你我不知道。
2)主祈从现(主句祈使句，从句一般现在时表将来;主句建议，从句条件)
Go pay more at other daycare if you don’t like Navy TV.
你要是不喜欢海军片，就多花钱去别家幼儿园吧。
If you want something , go get it. Period.
如果你有理想的话，就要去努力实现。就这样。
2.If引导的非真实条件状语从句
What would you say if a guy walked in for an interview without a shirt
on…
如果有个人连衬衫都没有穿就跑来面试，你会怎么想?
析：此句话条件句用了一般过去时，主句用了过去将来时。表示一种虚拟语气。
虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。
时态：可以表示过去，现在和将来的情况。它的基本特点是时态退后。
a. 同现在事实相反的假设。
句型 ： 条件从句， 主句
一般过去时， should( would) +动词原形
If they were here, they would help you.
3.直接引语变间接引语
-Christopher: Dad, listen to this. One day, a man was drowning in the
water. And a boat came by and said, "Do you need any help?"
-爸，你听这个，有天，一个人在水里快要淹死了，这时一只船过来问他“需要帮忙吗?”
-He said, "No, thank you. God will save me." Then another boat came by.
Said, "Do you need any help?"
-他回答说“不了，谢谢，上帝会救我的”，后来又有一只船过来问“需要帮忙吗?”
-And he said, "No, thank you. God will save me." Then he drowned, and he
went to heaven.
-他说“不用，谢谢了，上帝会救我的”后来他淹死了，上了天堂。
-And he said, "God, why didn't you save me?" And God said, "I sent you two
big boats, you dummy."
-他问“上帝啊，为什么你不救我?”上帝回答说“我不是派2艘大船去了吗，笨蛋”。
语法：直接引语变间接引语
考虑变化因素：1引导词2时态3语序4人称
1当引语为陈述句，引导词that
一般疑问句，引导词 if /whether
特殊疑问句，引导词特殊疑问词
2时态，主句一般现在时 从句时态不变
主句一般过去时 从句时态倒退一格。
3语序 陈述句语序
4 人称 根据逻辑说人话

3)-And he said, "God, why didn't you save me?"
