30、9_(strength)the training of medical staff around childrens health and promote knowledge of 10 _(balance)eating and drinking habits among their parents.(should)strengthenbalanced答案及解析：【语篇解读】这是一篇议论文。文章讲了在中国大陆，超重儿童越来越多。不运动、吃垃圾食品和喝碳酸饮料带来了世界上超重青少年的增长。为了应对中国肥胖儿童的增长，国务院今年发布了指导方针。1will reach 考查时态。根据时间状语in 2

31、025可判断出，是发生在将来的事情，用一般将来时。故填will reach。2that/which 考查定语从句。surpasses(超过)the population of Spain是一个定语从句，关系词在从句中作主语，指物。故填that/which。3were reported 考查时态、语态和主谓一致。“他们”和“报道”之间是被动关系，用被动语态，表示发生在过去的事情，用一般过去时，主语为表示复数意义的millions of them。故填were reported。4including 考查介词。文中表示“包括9100万肥胖儿童”，用介词，所以填including。5measures

32、 考查名词复数。作句子主语，用名词，文中表示“有效的措施”是复数意义。故填measures。6to 考查固定短语。句意为：不运动、吃垃圾食品和喝碳酸饮料造成了世界上超重青少年的增长。contribute to造成，是固定短语。故填to。7youths 考查名词单复数。句意为：不运动、吃垃圾食品和喝碳酸饮料造成了世界上超重青少年的增长。文中表示“超重青少年”，该空需要用名词。超重青少年不止一人，应填复数形式，故填youths。8To respond 考查非谓语动词。句意为：为了应对中国肥胖儿童的增长，国务院今年发布了指导方针。作目的状语，用不定式结构。故填To respond。9(should)

33、strengthen 考查虚拟语气。此空在从句中作谓语动词，要将名词strength变为动词strengthen；又因为that从句为urge所引导的宾语从句，从句中要用“should动词原形”表示虚拟语气，should可以省略。故填(should)strengthen。10balanced 考查形容词。该空修饰名词短语eating and drinking habits，用形容词。故填balanced。注意看全句子，of后宾语中心语为habits，而非of后接动名词balancing。.微写作根据以下要点，写一篇短文，其中至少包含一个附加疑问句。1通常来说我在周末锻炼，我觉得保持健康有助于学

34、习。2上周末，外面下雨了，所以我决定去健身房锻炼。3当我走进健身房的时候，有些人正在锻炼。4有个人正在做力量训练，尽力举重。5在另一个房间，有个健身教练(a fitness instructor)在教一些年轻人做瑜伽(yoga)。6每个人都应该锻炼，不是吗？One possible version：Usually I do some exercise on the weekend.I think keeping in good health can help me study well.Last weekend,it was raining outside so I decided to do
