Answer 1

分析 我们都需要锻炼，锻炼可以消耗我们每天所吃进的脂肪，使我们的身体充满能量．锻炼可以使你的心脏和肌肉强壮，锻炼还可以使你感到放松，如果你每天锻炼几次，你将保持心情愉快并且身体健康．有很多种锻炼的方式，你可以走，可以跑步、参加运动或者是游泳．然而，很多人并不能锻炼身体，它们的家离单位太远，除去开车上班他们没有别的选择，首先，这些人没有锻炼的机会，因为他们必须每天在车里坐二到四个小时，其次，开车很有挑战性，尤其是在车流高峰期，需要特别注意．这让人感到劳累．当这些人到家后，他们不想再锻炼身体．
    在一些西方国家，例如美国，人们锻炼也成问题，很多人没有得到足够的锻炼，他们必须从早晨工作到夜晚，所以他们没有时间锻炼，今天，西方很多人身体肥胖，这带来了很多健康问题．医生认为锻炼不仅可以使人减肥，而且可以改善人的健康状况，所以很多人尽量多锻炼，但是要改变状况需要付出时间，当人们看不到立竿见影的差异后，他们会失去信心放弃锻炼．
