状语从句及连词
1、everything depends on ________ we have enough time.
a. that b. how c. if d. whether
选d。介词之后以及动词discuss之后的宾语从句一般用whether，而不用if来引导。
2、______ i had done it i knew i had made a mistake.
a. hardly b. directly c. mostly d. nearly
选b。第一眼看四个词从形式上看都是以-ly结尾的形容词，但从句子结构看，空白处需要填连词。但不少学生受hardly…when…影响，可能很容易选a。其实，directly/immediately等少数副词具有连词的功能用来连接两个句子，意思是“一…….就…..”，相当于as soon as, the moment等用法。
3、 —what should we pay more attention to if we go north in winter, mum?
—nothing much. take warm clothes
the weather is cold.
a. as long as b. now that
c. if d. in case
选d。本题主要考查连接词的意义及对句子间的意义、关系的理解。as long as 意思是“只要”，表示条件；now that 意思是“既然；由于”，表示原因；if意思是“如果”，表示条件；in care意思是“以防，万一；免得”，表示条件。根据句子间的意义及关系可知本题的正确答案选d。
