题目内容

My mother goes shopping,______I must look after my little brother.
A．soB．becauseC．andD．but
A

试题分析：because 是从属连词，接表示直接原因的从句，一般放在主句的后面，也可放在主句前面，它表示的语气最强，在回答why的问句时，必须用because。as 是从属连词，说明一般的因果关系，语气比because弱，说明比较明显的原因，它引导的从句通常放在句首，有时也可放在句末。And是和的意思，表示并列或顺承；but表示转折，根据语境可知选择A.
点评：because只能放在句子中间,在它之前的是结果,后面的是原因. so做所以解释时也是放在句子中间,在它之前的是原因,后面的是结果.
