    【题目】________it in the flesh, I would never have known the flood in Thailand is so serious and people are suffering so much.

    A. Had I not seen B. If I did not see

    C. Should I not see D. Were I not seen

    【答案】A

    【解析】句意：要不是我亲眼所见，我不会知道泰国的洪灾是这么严重，人们受了这么多的苦。所给的空是虚拟语气的倒装句，正常语序应是If I had not seen...，句中省略了if，应将had提前构成倒装，故选A。

    语序，且此处表示过去将来，故选C。

    【题目】C

    Obesity(肥胖) has rapidly increased in young rural Chinese, a study has warned, because of socioeconomic changes originally. Researchers found 17% of boys and 9% of girls under the age of 19 were obese in 2014, which is 1% for each in 1985.

    The study used a stricter standard of the Body Mass Index (BMI) than the World Health Organization standard. ＂It is the worst explosion of childhood and adolescent obesity that I have ever seen,＂ Joe Perk from the European Association of Cardiology(心脏病协会) told AFP news agency(法新社).

    The study said China’s rapid socioeconomic and nutritional transition had led to an increase in energy intake and a decrease in physical activity. The traditional Chinese diet had shifted towards a diet ＂with high fat, high energy density and low dietary fibre＂.

    The percentage of overweight children has also grown from 0.7% to 16.4% for boys and from1.5% to nearly 14% for girls, the study said. The data was taken from six government surveys of rural school children in Shandong aged between 7 and 18. On the reason for the higher percentage of overweight and obesity in boys, the study said, ＂The traditional, social preference for sons, particularly in rural areas, may mean that boys are likely to enjoy more of the family’s resources.＂

    If the government and parents want to control the obesity, the researchers recommend that ＂some strategies should include annual monitoring, education on the pattern of nutrition, physical exercises and healthy dietary behavior＂. Otherwise there will be a severe influence.

    【1】What can we infer from the passage?

    A. The Chinese diet system is healthy now.

    B. Adolescent obesity problem is very serious in China.

    C. There are more physical activities in Chinese school children now.

    D. 17% of girls under the age of 19 were obese in 2014.

    【2】 How many ways are there to control obesity in the text?

    A. 3. B. 4. C. 5. D. 6.

    【3】Why is there a higher percentage of obesity in boys in China?

    A. The girls often lose weight in China.

    B. The boys exercise more than girls in China.

    C. The boys have an unhealthy diet in China.

    D. The parents prefer boys, so they can get more resources.

    【4】Which is the basic reason of obesity increasing so fast in China?

    A. Socioeconomic changes. B. Unhealthy dietary behavior.

    C. Lack of exercises. D. Air pollution.
