翻译练习15 Test 2 答案及解析：
1.lose contact with
lose contact with/lose touch with与……失去联系
2.are being developed
"be being done"现在进行时的被动语态表示此时此刻某事正在被做。其中动词be应随主语作相应变化。
3.has a strong influence on/effect on
influence/effect作名词(常与on连用)对…有影响力。
influence指"通过说服、举例等对行动、思想、性格等产生不易觉察到的,潜移默化的影响",如:Influenced by a high-school biology teacher, he took up the study of medicine.
effect指"实现"、"达成",着重"造成"一种特殊的效果,如:This book effected a change in my opinion.
4.can't have been cleaned
"情态动词+have done"表示推测，must/can/may/might/could各用于不同句型中，must只用于肯定句中，can/could不能用于肯定句中，may/might不能用于疑问句中。can't表示不可能，may not表示可能不。如题中推测的为过去的事情，情态动词后则用完成形式。
5.watched her injured son sent into the operation room.
see/watch…sb/sth.+done强调某动作的全过程，且宾语和动作间是被动关
