3、连接副词:when,where,why,how,how many,how long,how far,however,whenever,wherever (有词义,作从句的状语)

用法:
从结构上说,英语连接词分两大类:并列连词和从属连词。

并列连词连接两个或两个以上地位平等的字、词组或分句。例如:
(1) Air and water are indispensable to me.   
(2) She likes going out with friends or playing outdoor games.   
(3) Most workers have a good income, so they look very happy.   

从属连词连接两个或两个以上的分句,形成复杂句中的从属分句。例如:   
(4) He said that he did not want to go .   
(5) Many things have happened since I last saw him.   
(6) You may come if you want to.   

从属连词用来连接各种从句。
until(till)直到,在用until表达时间状语的句子中,主句中的动词是要十分小心去选择的。
如动词是持续行动词,它要用肯定句,如:
I studied hard until 12 o'clock last night.
如果动词是瞬间截止性动词,则要用否定句,如:
He didn't go to bed until his mother came back.
由since,for,by,before, 来引导的时间状语从句。
since 引导的时间状语是动作的开始时间,如:
I have studied English since 1990.
而by引导的时间状语通常是动作的结束时间,如:
I had learned 25 English songs by the end of last term.
