— When will the plane _____?
— At 11：35. Let's hurry up.
四个选项的含义分别是：take down 写下，记录；take off 起飞，脱掉；turn down 调低，拒绝；turn off 关闭。根据题干中的 the plane 可推断，所缺的短语是 take off，故答案为选项B。
Cathy checked her paper _____ so that she could get good grades this time.
careful形容词，意为“认真的”；carefully副词，意为“认真地”。结合选项可知句意为“凯苦认真地检查了她的试卷，以便这次她可以取得好成绩”。此处应用副词修饰动词checked，排除A、B；enough用作副词时意为“足够地”，修饰形容词或副词时应位于其后，故选选项D。
Her life was _____ so that she couldn't find time for hobbies.
full“满的，忙的"；free“空闲的”；relaxed“放松的”；quiet“安静的”。由she couldn't find time for hobbies.（她没有时间培养业余爱好）可知她很忙。故选A。
