1. C 2. D 3. A 4. E 5. B

The teacher and her daughter, the policeman and his wife are walking in the woods (树林). They find four eggs in a nest(鸟巢). Each of them takes an egg and yet one egg is left in the nest. How can this be?

The four identities actually only stand for 3 people: the teacher is the policeman's wife, so there are just 3 people in all. 3 people take 3 eggs away, so the last egg is still left in the nest.

这是一道趣味英语脑筋急转弯，我们可以发现题目里的身份是重叠的：老师就是警察的妻子，看似提到的“老师、老师的女儿、警察、警察的妻子”四个身份，实际对应的总人数只有3人。3个人每人拿走1个鸡蛋，总共只拿走3个鸡蛋，原本鸟巢里的4个鸡蛋自然就还剩下1个留在巢中，完全符合题目的描述。
