activities.Our questions were about exercise,use of the Internet and watching TV.Here are the results.We found that only fifteen percent of our students exercise every day.Forty-five percent exercise four to six times a week.Twenty percent exercise only one to three times a week.And twenty percent do not exercise at all!We all know that many students often go online,but we were surprised that ninety percent of them use the Internet every day.The other then percent use it at least three or four times a week.Most students use it for fun and not for homework.,The answers to our questions about watching television were also interesting.Only two percent of the students watch TV one to three times a week.Thirteen percent watch TV four to six times a week.And eighty-five percent watch TV every day!Although many students like to watch sports,game shows are the most popular.It is good to relax by using the Internet or watching game shows,but we think the best way to relax is through exercise.It is healthy for the mind and the body.Exercise such as playing sports is fun,and you can spend time with your friends and family as you play together.And remember,“old habits die hard”.So start exercising before its too late!,Complete the pie charts.,15,85,90,20,20,2,13,10,45,Discuss:Do you think the students are healthy?Why or why not?,15,85,90,20,20,2,13,10,45,Discuss:What advice

School about their food.Our questions were about their eating habits.Here are the results.We found seventy percent of the students eat cabbages every day.Five percent students eat cabbages once or twice a week.And twenty-five percent of the students eat cabbages three or four times a week.We all know that many students like to eat meat,but we were surprised that nobody eat fish everyday.Only fifteen percent students eat fish three or four times a week.The other eighty-five percent eat it once or twice a week.The answer to our questions about eating hamburgers were also interesting.Only five percent of the students eat hamburgers every day.Ninety percent students eat them only once or twice a week.And five percent eat them three or four times a week.In general,the students have quite healthy eating habits.But in my opinion,I think they should eat many kinds of vegetables not onl y cabbages.We should keep a balanced diet.So we should eat some fruit,too.But eat less meat.And we also need to drink milk every day.Its good for our health.To keep healthy,the important way is through exercise.Its healthy for the mind and the body.So start exercising quickly!,4.Although many students like to watch sports,game shows are the most popular.虽然很多学生喜欢看体育节目，但游戏类节目是最受欢迎的。,although 为连词，意为：“虽然，尽管”。注意：在英语中，当表示“虽然，但是.”这样的意思时，although和but不能在同一个句子中使用。也就是说，在一个句子中，有although就没有but，反之亦然。如：Although the car is old,it still runs well.=The car is old,but it still runs well.这辆小车旧了，但是依然跑得不错。,5.So start exercising before its too late!所以赶紧锻炼起来，不要等到来不及了。,Its too late 字面意思为“为时太晚，来不及了”是英语的一个常用表达。如：Now you know you are wrong,but its too late.你现在知道错了，已经太晚了。句中，Its too late 与before共同组成从句，表示“不要等到为时已晚；不要等到来不及的时候；趁还来的及”。如：You should work harder before its too late to catch up.你现在用功还赶得上。,3a Look at the
