四、重点语法：
（一）直接引语变间接引语
直接引用别人所说的话，被引用的句子被称为直接引语；用自己的话来转述别人的话，被转述的部分被称为间接引语。直接引语和间接引语在句中常作say, tell, ask, answer, think等动词的宾语。直接引语一般出现在引号之内。直接引语转化为间接引语时，由于转述时人称、时间和地点状语通常会发生变化，所以间接引语中人称、时态、指示代词、时间和地点都应根据具体情况进行相应的转化，不同种类的句子转化方法略有不同。但目前为止我们所学的主要变化的是人称，而时态、时间和地点一般不变。
直接引语为陈述句，变为间接引语时常由that引导（可省略），引语的动词常用say, tell等。如：The teacher siad, “Mike, you must bring your book to the class.”
The teacher told Mike (that) he must bring his book to the class.
直接引语是一般疑问句时，转化为间接引语时需用连词if（是否）来引导，并把问句变为陈述句的语序。如：Mary asked, “Mum, can you buy me a new dress?”
Mary asked her mother if she can buy her a new dress.
直接引语是特殊疑问句时，转化为间接引语需要把疑问句变为陈述句语序。如：
The teacher asked the new student, “Where are you from?”
The teacher asked the new student where he is ffrom.
直接引语为祈使句，变为间接引语时多用 “ask/tell/orer等+sb.+ to do”结构。如：
She said to him, “Come at five o’clock.”
She told him to come at five o’clock.
（二）‘used to’和 ‘be used to’
“used to”意为“过去经常做某事（而现在不了）”，表示过去的习惯或存在的情况，后面跟动词的话，要用动词的原形。如：I used to come to see my grndpa every week.我过去每个星期都去看望我爷爷。（但现在不去了）
“be used to”可解释为“习惯于”，后面跟动词的话要用现在分词。如：We are used to his carelessness. 我们习惯了他的粗心大意。再如：We can’t be used to living in such a small room.我们无法习惯于住在这样一个小房间里。
五、例题解析：
1、误：He spends a lot of time on playing computer games.
正：He spends a lot of time (in) playing computer games.
解析：spend（花费）后跟时间时，介词要用in，当in后有动词的现在分词时，in也可省略。当花费的是金钱时，后面的介词才用on,而且on不能省略。
2、误：Wood is used to making paper.
正：Wood is used to make paper.
解析：此处的be used to意为“被用来做…”,是被动语态的一种用法，所以use后跟的是不定式to do的结构。另外此句还可变为：Wood is used for making paper.
