二、特殊疑问句的用法
特殊疑问句指对句子中的某一部分进行提问的疑问句,像what color就经常对颜色进行提问,例: The sky is blue. (就划线部分提问) What color is the sky?
特殊疑问句体型的解题方法: ①根据划线部分,选定特殊疑问词。
②把除划线部分以外的句子变成一般疑问句。 记住一句顺口溜:定疑问词,变疑问句。 关于特殊疑问词的选择一般遵循以下规律: ①对“时间”进行提问,用when或what time; I had lunch at 12:15. (就划线部分提问) When did you have lunch?
②对“什么或职业”进行提问,用what: My father is a teacher(就划线部分提问) What is your father?
I liked go swimming when I was young. (就划线部分提问) What did you like when you were young? ③对“谁”进行提问用who或whom。
如:Li Lei is a doctor.→Who is a doctor?(对主语提问用who,对宾语提问时用who、whom均可) ④对“地点”进行提问用where。
如:The ball is under the bed.→Where is the ball ? ⑤对“原因”提问要用why:
He didn't come because he was ill.→Why didn't he come? ⑥对“方式”提问要用how:
He did it in that way.→How did he do it?
⑦对“多少”进行提问用how many或how much。how many适用于可数名词,how much适用于不可数名词:
I have a lot of money.→How much money do you have? He has been to China three times.→How many times has he been to China?
⑧提问“频率”用how often: I watch TV twice every week. →How often do you watch TV? 三、复习现在进行时的语法
现在进行时是指正在发生的动作或事件,动作发生的时间是“现在”,动作目前的状态是“正在进行中”。 基本结构
现在进行时的基本构成是:主语+be(am/is/are)+动词的现在分词形式(v+ing),具体表现如下: 第一人称单数 I+am+doing+Sth. I am reading a book:我正在看书 第一人称复数 We+are+doing +Sth.
We are playing football now:我们正在踢足球 第二人称单(复)数 You+are+doing+Sth.
You are looking at the blackboard: 你们正在看黑板 第三人称单数 He(She,it)+is+doing+Sth. She is playing basketball:她正在打篮球 第三人称复数 They+are+doing +Sth. They are watching TV:他们正在看电视
动词现在分词的变化规则
① 一般情况下,直接在动词后加-ing work ---- working; sleep ----- sleeping; ②动词以不发音的-e结尾,要去-e加-ing take ----- taking make ----- making dance ----- dancing ③重读闭音节,且末尾只有一个辅音字母的动词,要双写词尾字母,再加-ing: cut ----- cutting put ----- putting ④以ie结尾的动词,把ie变成y再加-ing,常用的有以下三个:lie ----- lying tie ----- tying die ----- dying 基本用法
现在进行时表示现在正在进行的动作或发生的事情: I am reading a book:我正在看书 She is playing basketball:她正在打篮球 句型转换
①在现在进行时的状态之下,把肯定句变成一般疑问句,只需要把be提前即可。
My father is reading a newspaper 变成一般疑问句: Is your father reading a newspaper? Yes, he is . No, he is′t ②在现在进行时的状态之下,把肯定句变成否定句,只需在be动词之后加not即可,如: I am working→I am not working.
现在进行时标志词:at the moment; now;look等。
