4 A Mary今天病了，如果她没生病，今天她就会去上学了。因为第一句说，Mary今天病了，所以本题考查的是与现在情况相反的事情，因之，主句用would、should、could+动词原型，从句用一般过去时。
5 B 先分开看此题，由于设空处在主句，所以先看主句，因为由主句看不出题目所表达的具体时间，所以再看从句，从句的时态是过去将来时，可以看出，主句要表达的是与未来情况相反的事情，那么主句就用could、shuold、would+动词原型。
6 C 先分开看此题，由于设空处在主句，所以先看主句，因为由主句看不出题目所表达的具体时间，所以再看从句，此从句是由but引导的转折句，所表达的时态是一般过去时，意为“我那时很忙”，所以，主句发生的事情是与过去事情相反的事情，因之，主句用could、should、would+动词原形，从句用过去完成时。
7 D 先分开看此题，实际上此题目没有从句，又由于设空处在主句，因为由主句看不出题目所表达的具体时间，所以再看前面的“witouth your help”，所以可以看出这是与过去事情相反的事情，因之，主句用could、should、would+动词原形，从句用过去完成时。
8 A 此题同7题
