【答案解析】

7.【答案】D。解析：考查現(xiàn)在完成進(jìn)行時(shí)。句意：自從幾年前，世界各國的領(lǐng)導(dǎo)人就指出了達(dá)成環(huán)境保護(hù)協(xié)議的必要性。“since+時(shí)間點(diǎn)”是現(xiàn)在完成時(shí)的標(biāo)志性時(shí)間狀語。題目中有時(shí)間狀語since years ago，且題目強(qiáng)調(diào)自從幾年前，世界各國的領(lǐng)導(dǎo)人就一直在強(qiáng)調(diào)達(dá)成環(huán)境保護(hù)協(xié)議的必要性，所以應(yīng)該用現(xiàn)在完成進(jìn)行時(shí)。選項(xiàng)A是過去完成進(jìn)行時(shí);B是一般過去時(shí);C是過去進(jìn)行時(shí);D是現(xiàn)在完成進(jìn)行時(shí)，符合題目，故選D。

8.【答案】B。解析：考查動(dòng)詞辨析。句意：非法移民應(yīng)該篩查疾病。be supposed to do sth. 應(yīng)該做某事，被期望做某事。故答案選B。believe認(rèn)為;assume承擔(dān)，假定，assume responsibility承擔(dān)責(zé)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(dāng)not until位于句首時(shí)，其后的主句要用倒裝結(jié)構(gòu)，其結(jié)構(gòu)為：Not until+從句/表時(shí)間的詞+助動(dòng)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(gè)房間。根據(jù)以上分析，not until位于句首，該句應(yīng)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(shí)態(tài)為一般過去時(shí)，所以主句倒裝時(shí)應(yīng)該借助的助動(dòng)詞是did，所以選項(xiàng)D為正確答案。
