网考网参考答案：C
网考网解析：
本题译文：要是你的打印机还有其他问题，请和经销商联系以获得帮助。本题考查虚拟语气。本句表示对现在和将来情况的虚拟：Should you have further problems其实是从If you should have further problems转化而来的，通常这类从句后面，主句的谓语用祈使语气或陈述语气，例如：Should you require anything，just give me a ring.(你要是需要什么就给我打电话。)Should I be free tomorrow，I will come to see you.(如果明天我有空，我会来看你。)由于本题的主句正是祈使句，从句显然应该由should引导，故C是正确答案。若答案为A，则主句谓语要用虚拟语气would+动词原形，而不用祈使语气。D.In case“万一，以免，以防”，后面一般跟现在时或者should+动词原形，例如：I always take an umbrella in case it rains.(我总是带上一把伞，以防下雨。)I wrote down her address in case I should forget it.(我记下了她的地址，免得忘了。) document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
