What Makes Me the Weight I Am?
There's no easy answer to this question.Your genetic makeup,the physical traits that get passed down to you from your parents,plays a big part in determining your size and weight. ______(46)But if your parents are smaller than average,you may want to rethink that professional basketball career!
The same goes for your body type.Have you ever heard someone say a person is"big boned"?It's a way of saying the person has a large frame,or skeleton.Big bones usually weigh more than small bones. ______(47) Like your height or body type,your genes have a lot to say about what your weight will be.But that's only part of the story.Being overweight can run in someone 's family , but it may not be because of their genes._______ (48 ) And even though some kids gain weight more easily than others , when they eat right and exercise , most kids can be a healthy and happy weight that's right for them.It's true the way you live can change the way you look.
How much you weigh is a balance between the calories you eat and the calories you use. ______(49)If you spend your free time watching TV, your body won' t use as many calories as it would if you played basketball,skated,or went for a walk.If you are in balance,your weight will stay right for you as you grow.But if you eat more and exercise less,you may become overweight.______(50)
选项 ______(49)
A:That's why it's possible for two kids with the same height but different weight,to both be the right weight.
B:If you eat more calories than your body needs to use,you will gain too much weight.
C:Poor eating and exercise habits also run in families and this may be the reason the members.of a family are overweight.
D:However , many overweight people have difficulty reaching their healthy body weight.
E:On the other hand, "you eat less and exercise more, you, may lose weight.
F:If both your parents are tall,there is a good chance you＇II be tall.
答案B
解析空格前后句中都出现了parents，因此判断空格处也谈及parents的可能性很大，因此首先注意F项。而且空格前句中的your size and weight呼应F项中的tall,而空格后句中的smal-ler也是在说身高的问题，因此判断F是答案。
由此空前文内容可知，人的骨骼有大小之分，而大骨架通常比小骨架要重，因此才有可能出现这种现象，即身高相同、体重不同的两个孩子体重均正常。
前一句讲，身体超重有可能在家族中代代相传，但又不一定是基因遗传所致，接下来的句子就应说明其原因，即不良的饮食与运动习惯也代代相传，而这可能正是家族成员普遍超重的原因。
空格前后句中都出现了“calories（热量）”，因此判断空格处出现该词的可能性较大，因此首先重点注意B项。空格后面的句子结构是“if you… , your body…”，该结构也正好与B呼应，形成排比结构，因此判断B是答案。
前一句表明，如果一个人吃得多而运动得少，就有可能超重。“反之亦然”，即“吃得少而运动得多，体重就会减轻”，这显然应该是下一句要表达的意思。
