1．________ (apply) the ointment(药膏) to the wound，the nurse carefully wrapped it up with a bandage. 解析：句意：在伤口处抹上软膏后，护士小心地把它用绷带包扎上。根据句子我们可以得知“是先抹上软膏”，因此是这个动作在先，所以要用having applied。

答案：Having applied 2．They will have you ________ (arrest) if you don't pay taxes，because it is everyone's duty to pay taxes. 解析：have sb. done表示“让某人遭遇某情况”。done表示的动作往往不是主语，更不是宾语执行的动作，而是主语让另外的人执行。

答案：arrested 3．He hurried to the booking office only ________ (tell) that all the tickets had been sold out. 解析：only to do是不定式作结果状语，表示意料之外的结果。又因为tell与句子的主语he之间构成逻辑上的动宾关系，故用不定式的被动结构。

答案：to be told 4．The river forms the ________ (divide) between the old and new parts of the city. 解析：句意：这条河是该城新旧两区的分界线。the后应该加名词，要用division。

答案：division 5．If only they ________ (be) here now, we would be able to celebrate their wedding anniversary. 解析：句意：如果他们现在在这里，我们就能庆祝他们的结婚纪念日了。句中we would be able to celebrate their wedding anniversary是假设的情况，if only后be动词用were。

答案：were 6．________ (finish) the task, he could afford to relax a bit. 解析：句意：完成任务后，他可以稍微放松些了。finish表示的动作与句子主语是主谓关系，且先于谓语动作发生，故填Having finished。

答案：Having finished 7．Unless________ (arrest) the murderer is likely to commit similar or further offences.

1

解析：句意：除非被逮捕，否则那个杀手还会犯类似或更严重的罪。罪犯是被抓住，并且从句的主语和主句的主语一致，所以省略从句的主语和be。

答案：arrested 8．I hurried to the railway station yesterday, only ________(find) that the train had left. 解析：only to do表示出乎意料的结果。

答案：to find 9. As a result of the heavy snow, two-thirds of

the

buildings

in

the

area need________ (repair)．

解析：句意：由于大雪，这个地区的三分之二的建筑物需要维修。need后面要用doing或to be done表示被动意义。

答案：repairing / to be repaired 10．—Sorry for being late. I was held up in the traffic. —It's all right. I________ (read) the newspaper, anyway. 解析：句意：——对不起我迟到了。由于堵车我耽搁了。——没关系。反正我一直在读报。现在完成进行时表示一个动作开始于过去，持续到现在，并强调现在还在进行。

答案：have been reading Ⅲ.完形填空
