People play different games in different seasons. Most people's favourite sport in summer is swimming. Skating and skiing are usually winter sports.

Chinese Body Mass Index(BMI体重指数)system describes overweight as BMI from 24 to 27.9 kg/m2 and obesity as BMI at or above 28 kg/m2. You can know your BMI with the following formula(公式). BMI＝weight in kg/(height in m)2 Researchers studied data from about 15.8 million people across about 250 cities in China. According to Chinese BMI standard, 34.8 percent of the studied population was overweight and 14.1 percent was obese. These people were aged 18 or above. There are several reasons why men are more likely to be obese. As fathers, husbands, and brothers, men usually have to stand long­term excessive(过多的)stress and negative feelings which can make the body produce more stress hormones(激素). Such hormones play a role in increasing fat collecting. In order to reduce(减少)stress, men often tend to drink alcohol, eat an unbalanced diet, and stay up late into the night. Some other habits, like sitting for too long without moving at work and sleeping irregularly(不规律地)are also closely related to obesity. All above can add to the risk of becoming obese. By region(地区), the percentage of overweight and obesity in the north was generally higher than that in the south, with Inner Mongolia(37.1 percent), Shandong(37.11 percent), and Hebei(36.6 percent)being the top three. People in higher BMI groups tend to have a greater number of complications(并发症). The early examination and intervention(干预活动)are important ways to prevent obesity­related complications. 34．Was the percentage of obesity in Hebei higher than that in Shandong according to the study? No./No, it wasn't. 35.[数学]If a boy is 1.5 m tall and his BMI is 24 kg/m2, how heavy is he? He is 54 kg./54 kg. 36．Why are men more likely to be obese according to the passage? Because of long­term excessive stress, negative feelings and unhealthy lifestyles. 37．If you become a little overweight, will you make up your mind to lose weight? Why or why not? Write 10 words or more. Yes. Because being overweight can lead to a number of complications. It's bad for our health.(开放性试题，答案不唯一) 学科网（北京）股份有限公司 $$
