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 weight 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 weight 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____1.[不定向选择题]第48题__________A.That's why it's possible for two kids with the same height, but different weights, to both be the right weigh B.If you eat more calories than your body needs to use, you will gain too much weigh C.Poor eating and exercise habits also run in families and this may be the reason the members of a family are overweigh D.However, many overweight people have difficulty reaching their healthy body weighE.On the other hand, if you eat less and exercise more, you may lose weighF.If both your parents are tall, there is a good chance you'll be talABCDEF确定 2.[不定向选择题]第47题__________A.That's why it's possible for two kids with the same height, but different weights, to both be the right weigh B.If you eat more calories than your body needs to use, you will gain too much weigh C.Poor eating and exercise habits also run in families and this may be the reason the members of a family are overweigh D.However, many overweight people have difficulty reaching their healthy body weighE.On the other hand, if you eat less and exercise more, you may lose weighF.If both your parents are tall, there is a good chance you'll be talABCDEF确定

1.参考答案：C
参考解析：该段讲导致超重的其他因素。空格前讲的“超重可能不是因为基因”，因此空格处填入其他导致超重的因素比较合理。C选项最合适：不良饮食和锻炼习惯也会影响家庭，从而成为家庭成员超重的原因。故选C。?
2.参考答案：A
参考解析：该段讲的是骨架(skeleton)的大小对体重的影响。空格前一句讲的是“大骨架的重量会较重”，空格处应填入对此解释的现象：这就是为什么两个孩子身高相同，体重相对于正常重量来讲却是不相同的。因此A最合适。?3.[不定向选择题]第50题__________A.That's why it's possible for two kids with the same height, but different weights, to both be the right weigh B.If you eat more calories than your body needs to use, you will gain too much weigh C.Poor eating and exercise habits also run in families and this may be the reason the members of a family are overweigh D.However, many overweight people have difficulty reaching their healthy body weighE.On the other hand, if you eat less and exercise more, you may lose weighF.If both your parents are tall, there is a good chance you'll be talABCDEF确定
