问题
______ you ______ further problems with your printer, contact your dealer for advice.
选项
A、If, had
B、Have, had
C、Should, have
D、In case, had
答案
C
解析
本句的主句使用了祈使句,而非虚拟,因此从句应理解成对真实情形的一种假设。A项使用一般过去时,是对现在或将来情况的虚拟,而if真实条件句应使用一般现在时表示将来,所以A不正确,应该使用if you have...;B和C都省略了if,B项have had是对过去情况的虚拟,不正确:C项中的should用在假设句中,加强语气,should have是对将来情况的假设,故C为正确答案:D项Incase“万一,以防”引导的从句使用一般现在时或should+动词原形,不能用had。
