【答案解析】

7.【答案】D。解析：考查现在完成进行时。句意：自从几年前，世界各国的领导人就指出了达成环境保护协议的必要性。“since+时间点”是现在完成时的标志性时间状语。题目中有时间状语since years ago，且题目强调自从几年前，世界各国的领导人就一直在强调达成环境保护协议的必要性，所以应该用现在完成进行时。选项A是过去完成进行时;B是一般过去时;C是过去进行时;D是现在完成进行时，符合题目，故选D。

8.【答案】B。解析：考查动词辨析。句意：非法移民应该筛查疾病。be supposed to do sth. 应该做某事，被期望做某事。故答案选B。believe认为;assume承担，假定，assume responsibility承担责任，assume that...假定;imagine想象，猜想。

9.【答案】D。解析：考查倒装句。句意：直到生病的小女孩上床睡觉，疲惫的母亲才离开病房。当not until位于句首时，其后的主句要用倒装结构，其结构为：Not until+从句/表时间的词+助动词+(主句)主语+谓语+……，例如：He didn’t leave the room until the rain stopped. / Not until the rain stopped did he leave the room. 雨停了之后他才离开这个房间。根据以上分析，not until位于句首，该句应该用倒装句，故排除A、C。根据题干中的“went to bed”可知，该句的时态为一般过去时，所以主句倒装时应该借助的助动词是did，所以选项D为正确答案。
