完形填空.标准答案分别是changing和healthy,这两个空我都不会,
Yes,it's true!British children are getting fat,but they are also growing in other ways.Studies show that the height and weight of modern ten-year-olds are different from the height and weight of their parents at ten.British ten-year-olds are on average(平均) 141 cm tall(138—139 cm in 1972).The same studies show a 17% increase in weight.
The studies don't give reasons for this,but we can guess that the children are ___ for two main reasons:diet and exercise.These days children eat c___ food a lot of time,and this explains the increase in height to 141 cm,but they also eat a lot of unhealthy food,for example,sweets,chips,cakes and chocolates.After school,many of today's children sit down all evening.They watch TV,listen to music,or do their homework,but they often don't take any exercise.

Answer 1

这篇文章主要是介绍青少年成长变化的,虽然有英国孩子在变胖,但身高平均值也增长了.第二段交代产生变化的原因.所以,动词谓语要用表示变化的动词,因为前面有are,所以用进行时态.变化动词主要有turn（颜色）,become(身份）,get(状态）以及change.get已经用过,所以合适的就是change了.
第二段首先交代的是身高增长原因,这是好结果,所以要用表示褒义的词,再看but后面交代的是变胖原因,用的是贬义词unhealthy.因为but前后是对比关系,后面用unhealthy,那前面肯定是healthy.
