if(=even thoug)即使，用来引导让步状语从句
up走上前来，走近，ck where he had been.
He said,“These books are mine.”
→He said that those books were his.
(二)直接引语改为间接引语时，都使用陈述语序，但是由于原句的句式不同，所以变成间接引语时所用的连词会有所不同。直接引语假如是一般疑问句，用连接词whether或if;假如是特别疑问句，则用疑问词引导间接引语。转述的动词一般用asked，可以在其后加上一个间接宾语me, him, her, us等。如：
She said,“Is your father at home?”
→She asked me if/whether my father was at home.
“What do you do every Sunday?”My friend asked me.
→My friend asked me what I did every Sunday.
直接引语假如是祈使句，改为间接引语时，要将祈使句的动词原形变为带to的不定式，并在不定式的前面依据原句的语气(即恳求或命令)加上ask, tell, order等动词，假如祈使句为否认式，则在不定式前加not。其句型为：ask / tell / order someone (not) to do something. 例如：
She said to us,“Please sit down.”
→She asked us to sit down.
He said to him,“Go away!”
→He ordered him to go away.
He said, “Don’t make so much noise, boys.”
→He told the boys not to make so much noise.
