一题选择C，首先根据语态为被动排除B，再根据句子意思：必要的行动必须被执行，以确保学生能够感受到并且在学校安全。选项应有“必须”之意，故选择C。
二题选择B，看你给的选项主要是纠结于最后一个空，其实不难，分数加名词后面的谓语由名词单复数决定。这句话中，three fourths of the materials是主语，i listened to at the beginning of the exam是定语从句，省略了that，简化句子就是：I think three fourths of the materials are easy，这样就显得清晰明了了。
三题选择A，这是一个定语从句，先行词是the novel，在定语从句中做read的宾语，因此选择A，相当于省略了that，此外，如果作为填空题，这个空还可以填that 或者which。
不知道我有没有表达清楚，如果你有什么疑问可以再问我。
