【答案解析】

7.【答案】D。解析：考查現(xiàn)在完成進行時。句意：自從幾年前，世界各國的領導人就指出了達成環(huán)境保護協(xié)議的必要性。“since+時間點”是現(xiàn)在完成時的標志性時間狀語。題目中有時間狀語since years ago，且題目強調自從幾年前，世界各國的領導人就一直在強調達成環(huán)境保護協(xié)議的必要性，所以應該用現(xiàn)在完成進行時。選項A是過去完成進行時;B是一般過去時;C是過去進行時;D是現(xiàn)在完成進行時，符合題目，故選D。

8.【答案】B。解析：考查動詞辨析。句意：非法移民應該篩查疾病。be supposed to do sth. 應該做某事，被期望做某事。故答案選B。believe認為;assume承擔，假定，assume responsibility承擔責任，assume that...假定;imagine想象，猜想。

9.【答案】D。解析：考查倒裝句。句意：直到生病的小女孩上床睡覺，疲憊的母親才離開病房。當not until位于句首時，其后的主句要用倒裝結構，其結構為：Not until+從句/表時間的詞+助動詞+(主句)主語+謂語+……，例如：He didn’t leave the room until the rain stopped. / Not until the rain stopped did he leave the room. 雨停了之后他才離開這個房間。根據(jù)以上分析，not until位于句首，該句應該用倒裝句，故排除A、C。根據(jù)題干中的“went to bed”可知，該句的時態(tài)為一般過去時，所以主句倒裝時應該借助的助動詞是did，所以選項D為正確答案。
