I,m just a senior in high school. I work parttime at a local store called Baskin Robbins so that I can make a little money. In and outside of work, I always wear a
1
and try to be nice to others.
But lately, I,ve been
2
by some people who always help others. So, today, when I went to work, I decided I would take my first big step and truly help a stranger.
Two young girls came into the
3
and looked around. I offered them my
4
“Welcome to Baskin Robbins” greeting. A couple of minutes later one of them finally decided upon the flavor(味道) of ice cream-chocolate. So then, I made a big spoon, put it in a cone(锥形蛋卷筒) and
5
it to her. Sadly, though, the other girl didn,t get anything even though I could tell she was looking at the many kinds of
6
and wanted to have one.
It was at this time that the other girl, who obviously was the younger sister,
7
,
揑 wish I could have one.?I knew when I heard this comment that it was my
8
to do something for her. So,he I told her that I would

her ice cream. She immediately calmed down though she didn,t believe what she
10
.I asked her what flavor she wanted and handed her treat. I then
11
out the ＄3 for it and placed the money in the counter.
She was so
12
and her older sister was surprised. It was
13
good to help this girl and make her feel special for a moment. I turned around and found that my
14
all looked at me like I was crazy. But, I didn,t care that I spent a little, because the feeling I
15
from my action was worth a million dollars.

议论文的阅读
Two American scientists told the people in industrial nations that they would be much healthier if they ate more of the same kind of foods eaten by humans living more than 10,000 years ago．
The scientists say that the human body has changed very little since human first appeared on the earth,but the way we live has changed greatly．Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses．These new sicknesses were not known in ancient times．So they are called “diseases of civilization”．Many cancers and diseases of the blood system,including heart attacks and strokes（中风）are examples of such diseases．
Scientists noted that early stoneage people used very little alcohol（酒精）or tobacco,probably none．Ancient people also got a great deal of physical exercise,but a change in food is one of the main differences between life in ancient times and life today．
Stone age people hunted wild animals for their meat,which had much less fat than farm animals．They also ate a lot of fresh wild vegetables and fruits． They did not use milk and other dairy products（乳制品）,and they made very little use of grains．But today,we eat a large amount of dairy products and grain foods．We eat six times more salt than stoneage people．We eat more sugar．We eat twice as much fat but only one third as much protein and much less vitamin C．
People today probably do not want to live as people thousands of years ago did,but scientists say that we would be much healthier if we ate as those ancient people did,cutting the amount of fatty,salty and sweet foods．
