Mary and Linda are twin sisters．They are my 1 ,and my good friends,too．We live in the same town．so we can 2 each other very often．We know each other quite well．Although Mary and Linda look the same,they are quite 3 in many ways．Mary is a few hours older,but a little 4 ．She is heavier and smarter．How about Linda,then?She is thinner and more outgoing．They both like sports,but Linda is more 5 ．She is better at sports than Mary．They are both very popular in school．
It was a fine day．Linda went to the park by 1 ．When she got to the park gate,it was 11 o'clock．After 10 minutes,Linda stopped her bike and put it beside the road．She walked away to look at some people 2 in the lake．While Linda was looking,a man went quietly to her bike．He was a 3 and stole the bike．When Linda came back,her bike was missing．She Was very 4 and she called the 5 right away．
It's a 1 Sunday morning．Some good friends are going 2 a field trip to the Yellow Mountain．They are going to 3 a picnic on the top of the mountain．Every-one takes some food and drink 4 them． 5 two hours later, they are all tired and thirsty．They have to stop 6 a rest and drink．Then they go on 7 ．They have a lot of problems 8 to the top．Linda often goes the 9 way, Hill trips over a stone(石头), Sam has to tie his shoes, Ed can't 10 his heavy bag, Lucy hikes too slowly．But they help each other, and at last they get to the top．They have a nice lunch and a good time．
