Question

请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词．

　　We all need exercise．Exercise uses up food we eat and keeps the body energetic．It works your muscles and makes your heart work hard so as to send blood to your muscles．So exercise makes your heart and muscles strong．Exercise also makes you feel refreshed．If you take regular exercises you will stay happy and healthy．

　　Some Western countries such as the United States have problems with exercise．In the US many people lack exercise because it is hard for them．People have to work from dawn till dusk so they don't have time to take exercise．They work in office buildings sitting in chairs all day long in front of computers．They cannot get much exercise sitting at desk passively．

　　Some Westerners can get exercise walking from their homes to work．However the majority of people cannot do this．It is too far from their homes to their offices．They have no choice but to drive to work．In fact some have to drive one or two hours to their offices．This is unfavourable in two ways．First these people don't have a chance to exercise because they are sitting in their cars for two to four hours each day．Second driving is challenging especially in rush hours and calls for too much attention．It makes a person very tired．So when these people arrive home at night they don't have the desire to take exercise after work．

　　Today many people in the West are overweight which causes health problems for them．Doctors say exercise can help people both lose weight and improve their health．So many people are trying to get more exercise．But it takes time to change and when people don't see a difference right away they will be discouraged and stop exercising．
