解析：
【小题1】delighted 形容词开心的：delighted.
【小题2】acquiring 固定词组spend some time doing sth. 所以这里使用acquiring.
【小题3】arranged 动词安排：arrange.句意：Beth安排了一次与市场部主管的会议。
【小题4】approve 动词批准：approve.句意：如果他的父母同意，Don才会买买买那辆摩托车。
【小题5】quarrelling 固定结构：hear sb doing sth听见某人正在做某事。Hear sb do sth听见某人做了某事；
我能够听见他们在隔壁吵架。是指正在进行的事情。
【小题6】Recycled 动词回收利用：recycle.塑料瓶可以被回收利用再制成衣服。本句使用被动语态，故使用过去分词的形式。
【小题7】polluted 动词污染：pollute。本句是被动语态，故使用过去分词的形式。
【小题8】lacks 动词缺乏lack。与needs是并列的形式，故使用lacks.
