现在完成进行时
现在完成进行时表示动作从过去某一时间开始，一直延续到现在还未结束。现在完成进行时有时也可用来表示经常的、反复的动作。
(1) 结构：have / has + been + V-ing
(2) 与since或for引导的时间状语连用；since后接动作开始的时间，for后面接一段时间；对since或for引导的时间状语提问时要用how long 。
(3) 否定形式是在have / has后加not构成，可缩写为haven’t / hasn’t。
(4) 一般疑问句形式是将have / has提至主语前；肯定回答用“Yes, 主语+have / has.”，否定回答用“No, 主语+haven’t / hasn’t.”。
e.g. a. -How long have you been drawing?
-I have been drawing for two hours.
b. -How long has Maria been playing the piano?

定语从句
定语从句是在复合句中起定语作用， 修饰名词、代词或整个主句的从句。被定语从句修饰的词叫先行词。引导定语从句的关系词有关系代词(that, which, who, whom, whose等) 和关系副词(where, when, why)。
关系词在定语从句中的作用：
①连接主句和定语从句；
②指代先行词；
③在定语从句中充当一定的成分。
(1)关系代词that与which
在定语从句中，关系代词that既可指人，也可指物，which一般用于指物。
在指物时，二者一般可以互换，但非限制性定语从句中多用which引导。
e.g. The old town has narrow streets and small houses that are built close to each other.
That evening, which I will tell you more about later, I ended up working very late.
(2)关系代词who与whom
who指人，是主格，在定语从句中作主语，一般可用that替换。
whom指人，是宾格，在定语从句中作 宾语。在口语和非正式文体中可用who 或that替换，也可以省略。
