读读看! 在户外行走很舒服，亚力克斯每个星期有三天会走路上班。他都走多远？他走3英里去上班，再走3英里回家。罗柏平时也会走路。他不管什么天气都会去散步，在下雨和下雪的日子也不例外。不过，他不爬公寓里的楼梯，因为他住在10楼!
Read it! It＇s nice to walk outside-. Alex walks to work three times a week. How far does he walk？ He walks three miles to work and three miles home. Rob walks, too. He walks in all kinds of weather. He walks in the rain and the snow. But he doesn＇t walk up the stairs in his apartment building. Because he lives on the 10th floor!
