参考答案：
1.正确答案：B答案解析：with用于与make contact搭配。本题使用的短语是make contact with sb.whom在本句中引导的句子做介词with的宾语。由于位于介词后面，所以用宾格形式whom.
2.正确答案：B答案解析：where在本句中引导表语从句。句意：这就是我们的不同之所在。
3.正确答案：A答案解析：isolate sb/sth from sb/sth是固定搭配。
4.正确答案：A答案解析：本句是对现在的虚拟，所以条件状语从句用过去时。同时在虚拟语气中，一般不用was而一律用were，所以答案是A.
5.正确答案：A答案解析：本题的考点是：That引导的主语从句，注意that引导的主语从句在句中只起到连接作用，没有意义，也不做任何成分。
