2、ng when we arrived.(指时间点)When we were at school, we went to the library every day.(在一段时间内 )whilewhile 意思是“当的时候”或“在某一段时间里”。主句中的动作或事情在从句中的动作或事情的进展过程中发生，从句中的动词一般要用延续性动词。在 when 表示a period of time 时，两者可以互换。Please dont talk so loud while others are working.He fell asleep while/when reading.

8、yet 连用。Although they are poor,(yet)they are warm-hearted.（2）even if 或 even though 引导让步状语从句，表示“即使”，“纵然” ，用来使人注意下文所强调内容的性质。Ill get there even if(though)I have to sell my house to get enough money to go by air.（3）no matter 后接上 who、what、where、how 等疑问词，也可以在这类疑问词后面加上 ever 构成 whoever、whatever、wherever 、how

Im leaving because Im full.for 虽然表示不知道的原因，但其语气较 because 要弱得多，是可说可不说的话，它只能置于主句之后，这时，for 是并列连词。如果不是因果关系，而是对前面主句的内容
11、加以解释或推断时，只能用 for。如：Its morning now, for the birds are singing.（很显然，鸟叫不可能是“现在已是早上” 的原因。）（2）表示已经知道的原因时用 as 或 since,即某种原因在说话人看来已经很明显，或已为听话人所熟悉，因此它是句中不很重要的部分。since 要比 as 正式一些，它们通常被置于语句之前，但有时却相反。Seeing all of the children already seated, he said,“Since everyone is here, lets start.”(3)下列情况下只能使用 because:在
