3．直接引语是特殊疑问句，变成间接引语时要把特殊疑问句变成由疑问词（when，where，how等）引导的宾语从句，还要把疑问句的语序改成陈述句的语序。此外，前述的三点注意事项同样适用于这种情况。例如：
Tire students asked the farmer, “When do you harvest the wheat?”
→The students asked the farmer when he harvested the wheat.
→“What are you doing here, Mary?” John asked.
→John asked Mary what she was doing there.
→“When will she leave for Beijing?” Mr Smith asked me.
→Mr Smith asked me when she would leave for Beijing.
4．直接引语是祈使句，变成间接引语时，要把祈使句变成一个不定式短语，同时根据口气选用适当的谓语动词，如ask（请），tell（让），order（命令）等。例如：
He said to the farmers, “Do things at the right fame of year.”
→He told the farmers to do things at the right time of the year.
“Open your books. Please,” he said.
→He asked us to open our books,
“Dont turn off the light,” the teacher said.
→The teacher told me not to turn off the light.
辨析condition, situation
两个词都有“情况，形势”的意思。

What are conditions like in your country? 你们国家的情形如何？
How do you analyze the present economic situation? 你怎样分析当前的经济形势？

We wish to advise you that you now owe the bank $500.你现欠银行五百美元,特此通知。
I suggested that it would be quicker to travel by train. 我建议说坐火车旅行要快一些。
不同点：
1） advise sb. to do sth.
2） suggest doing sth.
He advised farmers to choose the best-heads. 他劝告农民要挑选最好的谷穗。
He suggested changing the plan．他建议改变这个计划。
辨析point out, point in, point to
point out指出，常用于借喻中，后接名词和that从句。
point in表示具体的“指”。英语可以说point a finger (gun) at ab. （用手指（枪）指某人）。但更常见的是其不及物动词的用法。例如：
point to指着；指向，有时与point at同义，但一般用于较远的事物。此外，point to还有“指向”，“
