Getting plenty of exercise is very important.I enjoy 11 very much.Last Summer,I went to the beach every day.I plan to go there this summer too,12 I may not be able to.I have a new job.Sometimes I have to work until 13 at night.Though I now work more hours than I used to,I do receive a larger salary.I didn\'t receive much pay on my old job.I like 14 new job,but had I known that it would take up so much of my free time,I 15 it.I prefer swimming to spending money.
I have heared that riding a bike is good exercise.Maybe I will be able to
16 enough money to buy a bike.My neighbour,Mrs.Wilson,has a bicycle that I could borrow from her,but I would rather own my own bike.If I used 17 ,I would worry about damaging it.Since I 18 more money now,I think that I can afford to buy my own.Getting a bike is really a good idea,because while I am riding to and from work,I will be getting exercise at the same time.It\'s easier to get to the beach by bike too.I might be able to go swimming every day 19 .This new job is great:I\'m very 20 .This will be a summer full of exercise.
中18与19空中的because while I am riding to and from work一句to and from为什么不能用up and down 代替?

此处意思是：当我骑车往返上班时,有方向性
up and down的意思是上上下下,一般有高度上的变化,在此处并不适合
再问：可我查了字典，up and down 也有来回、往复的意思？
再答：不能单从意思上选择，相似意思的英语很多，要选最合适的。比如来自哪或去哪儿，一般介词用from/to，此处是指上班地点与家之前的往返，相比来说较合适
