1.实际上这是一个简单的数学题。我们把Betty现在的年龄设为x，三年后的年龄为x＋3，三年前为x-3，列成等式则是：3(x-3)=x＋3。解方程后x=3。所以，她的年龄是3岁。应这样回答：She's 3 years old now.
2.看了这个题，有些人会认为玩具船不下水。但并非全都如此。有些玩具船是要下水的。但是，宇宙飞船是从来不下水的。应回答：A spaceship.
3.我们都知道，过了星期日就是星期一。但是在词典上，Monday的第一个字母是m，Sunday的第一个字母是s。s是排在m后面的。应当回答：In a dictionary.
4.这个题涉及little的用法。a little是指“少许”，而little是“几乎没有”。一支没有墨水的笔，借了也是没有用处的。因此，应当借有墨水的笔。其答案是：I'll borrow Mike’s pen.
5.如果某种东西是固定的，参与分东西的人越多，分的东西越少。但不至于三个人就一点都没有了。但是作为秘密，知道的人越多，就不能成为秘密。应当回答：A secret.
