1、以约30个词概括短文的要点：

45. D。 细节理解题。根据文章倒数第二段“Fitness results in completing the tasks of daily living, working a full day, and still having energy to participate in recreational activities.”可知，有了健康的体魄就会有更充足的精力来工作和休闲。

44. A。 推理判断题。从第一段的“We disabled can - and should be - as active as anyone else.”可以判断作者自己也是个残疾人。

43. B。 细节理解题。根据第二段第二句“Experts recommend that spending as little as 30 minutes each day on physical activities provides benefits including lower risk of heart disease, cancer, high blood pressure, diabetes and other serious diseases.”可知，A、C和D三项都是在描述运动的好处，而根据文章第三段最后一句可知B选项说的是水的作用，因此不正确。

42. D。 猜测词义题。根据后面的“...which is confirmed by scientists.”可知，每日八杯水的作用已经被科学家证实了，因此选D项。

41. B。 写作目的题。根据最后一段“So let’s all get out there and do some exercise!”可知，作者的写作目的是号召大家运动起来，因此选B项。
