N：even if, even though 表示“即使”，“纵使”之意，含有一种假设。 这两个复合连词的意思基本相同。even if引导的让步从句含有强烈的假定性，可用来表示与事实相反的假设，但不能用来描述已经发生的事实。而even though引导让步状语从句时，是以从句的内容为先决条件的e.g。 Well make a trip even if/though the weather is bad. Even though he is poor, she loves him. (=He is poor, yet she loves him.)2）特殊疑问词when, where, how 加-ever构成的复合词也可以引导让步状语从句，意为“不论时候”，“不论哪里”，“无论”，在口语中还可用no matter + 特殊疑问词来构成。e.g. You can come over to my house whenever you want to.真题 24. _ many children like KFC, I think theyd better try not to eat it too often.
