数据推算题
此题要求学生就文章提供的数据，以及数据与文中其他信息的关系做简单计算和推断。
Visit Swansea Zoo
Come and see the Indian elephants and the new tigers from America. The bears are waiting to meet you, and the monkeys from China are waiting to throw things at you. The lovely dogs from Australia are waiting to laugh at you, and the giraffes from Zambia are waiting to look down on you.
Tickets Opening time
Grown-ups: $ 3 9:00 am --- 4:00 pm
Children: Over 12:$2 except Friday
Under 12: Free 10:00 am -- 3:00 pm
（ ）1. How much does Mr Smith have to pay if he visits the zoo with his sons of fourteen and ten?
A. $2.00 b. $5.00 C. $4.00 D. $3.00
（ ）2. Which of the following is the visiting time?
A. 8:30 am, Wed B. 9:30 am, Fri
C. 3:00 pm, Sun D. 4:00 pm, Tue
做此类题一要抓住有关的数据，二要从众多的信息中找出那些有用的信息，三要抓住一些关键词。实际上，上述两题都可看作数据推算题，一题是算钱，另一题是算时间。
通过阅读我们发现布告中的所有数据都是有用的，那么关键词是：grown-ups, children, over 12, under 12, opening time, except Friday。第一题中Mr Smith是成人，须买3块钱的门票，他一个14岁的儿子需买2块钱的门票，另一个不满12岁的儿子可免票，所以Mr Smith先生需花5块钱，B是正确答案。第二题C是正确答案。
