参考答案：
1. 答案：B 解析：prevent from 是固定搭配。from 是介词，后面须有名词或名词的等同词作宾语。如：They prevented the disease from spreading. /Jack did that to prevent the children from being hurt.
2. 答案：D 解析：to work 在句中作主语the slaves 的补足语。如果不用被动语态，因为make 是特殊动词，则work 前不用to。例如：Harry made Paul go at once. 改成被动语态则是：Paul was made to go at once.
3. 答案：D 解析：had been prepared 发生在returned 之前，故用过去完成时。此处须用被动语态。例如：When the advance payment was paid, the project had already been started.
4. 答案：D 解析：用过去时的被动语态。was met 的时间发生在arrived 的同时，故都用过去时。又如：At the time when the child was about to touch the dog, it was released by his father.
5. 答案：C 解析：既然是“今天就说到这儿”，说(say)的时态肯定是现在完成时。注意要用被动语态。又如：Now we have done whatever has not been done by that group./ Too much has been said about car accidents.
