5．(天津高考改编)Tom had(have)to turn down the invitation to the party last weekend because he was too busy.

解析：考查情态动词的用法。句意：Harry感到不舒服。他一定是在昨晚的聚会上喝了太多的酒。由第一句中的“uncomfortable”及第二句中的时间状语“last night”提示，此处强调对过去发生动作的推测。用must have done。

11．Mark needn't have hurried.After driving at top speed，he arrived half an hour early.

解析：考查情态动词。句意：迈克本来不必那么匆忙的。在高速驾驶之后，他提前半个小时到达了。根据后面的语境，提前半个小时到达，说明Mark本来不必那么匆忙，所以用needn't have done结构，表示“本来不必做某事而实际上做了”。

12．They should have arrived at lunchtime but their flight was delayed.

解析：考查虚拟语气的用法。句意为：他们本该午饭时到达，但他们的航班推迟了。should have done本来应该做某事，而实际没做。but their flight was delayed这样的结果，说明他们本来该到达却没有到达。

13．We've had a good start，but next，more work needsto_be_done/doing(do) to achieve the final success.

15．(2015·重庆，12改编)You must be Carol.You haven't changed a bit after all these years.

解析：根据后半句可知，说话者完全认出了卡萝尔，猜测的语气十分肯定，且在肯定句中，所以填must。
