Food British people like good food, and more than half of them go to a restaurant every month. Fast food is also very popular---30% of all adults have a hamburger every three months, but 46% have fish and chips!
Sports
British people don’t do a lot of sports. Only 17% of people go swimming every week, about 9% go cycling and 8% play golf--- and only 6% of people play football (but 32% go to watch it). Cinema and TV Films are very popular in Britain, and about 60% of the young people go to the cinema every month. At home, men watch TV for about three hours every day ---30 minutes more than women.
Holidays British people love going on holiday, and have 56 holidays every year. Most of these holidays aren’t spent in the UK---27% are in Spain. 10% are in the USA, and 9% are in France. Maybe this is because the weather in Britain isn’t very good!
Presents
British people don’t send others expensive presents like other Europeans. They often send chocolates, wine and flowers of good quality.

（2）芳芳家四月份用水多少立方米？
（3）芳芳家六月份应交水费多少元？
习题答案:
1、商是 8 ，余数是 300 。
2、98%
3、1.5米
4、24套
5、6张
6、30平方厘米
7、 6÷1/2000=12000厘米=120米， 4÷1/2000=8000厘米=80米
120×80÷2=4800平方米。
8、（60+7.5）÷90%=75(元)
9、600÷（1/3-2/7）=12600（个）
10、（1）：五月份用水量是：238.5-231=7.5（立方米）
（26-7.5×2.8）÷（4.8-2.8）=2.5（立方米） 享受2.8元/立方米水的用量是：7.5-2.5=5（立方米）
（2）：2.8×5=14元>12.6元。因此，四月份用水量是：12.6÷2.8=4.5（立方米）
（3）：250-238.5=11.5（立方米）>5（立方米）
因此六月份应交水费： 2.8×5+4.8×（11.5-5）=45.2（元）
