知识点讲解
语法----直接引语变成间接引语
总结直接引语变成间接引语有四种情况：
l．直接引语是陈述句，变成间接引语时，要把陈述句变成由that引导的宾语从句。例如：
He said: “Die best seed-heads should be hung up to dry.”
→He said that the best seed-heads should be hung up to dry.
直接引语是陈述句，变成间接引语时要注意三点：
l）时态的一致；
2）对人称代词和物主代词的相应调整；
3）某些时间和地点状语的相应调整。
例如：
Alice said, “I’ve just got a letter from my father.”
→Alice said that she had just got a letter from her father.
Mr Black said, “I arrived yesterday.”
→Mr Black said that he had arrived the day before.
2．直接引语是一般疑问句，变成间接引语时要把一般疑问句变成由if/ whether（是否）引导的宾语从句，同时将语序改成陈述句语序。例如：
He asked her, “Do they agree to sow wheat close together?”
→He asked her if they agreed to sow wheat close together.
直接引语是一般疑问句，变成间接引语时，除了要用if/whether来引导宾语从句外，前述的三点注意事项同样适用于这种情况。例如：
Alice asked Mike, “Have you finished doing your homework?”
→Alice asked Mike if/whether he had finished doing his homework.
Mrs Turner asked me, “Do you know where Tom works?”
→Mrs Turner asked me if/whether I knew where Tom worked.
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。
condition表示“情况，环境”时多用复数。当我们表示具体的工作、生活、居住“环境”“条件”时，用condition。
situation表“形势”时为正式用语。
Their wages and working conditions must be improved. 他们的工资、工作条件必须改进。
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？
辨析advise, suggest
相同点：两个动词都有“建议”之意，并且二者都可接+that –clause
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”，“，Unit 24 The science of farmingle－教案
