　　I’m seventeen. I had worked as a box boy at a supermarket in Los Angeles. People came to the counter and you put things in their bags for them. And carried things to their cars. It was hard work.

　　While working, you wear a plate with your name on it. I once met someone I knew years ago. I remembered hes name and said,“Mr Castle, how are you?”we talked about this and that.As he left, he said," It was nice talking to you,Brett.”I helt great,he remembered me. Then I looked down at my name plate. Oh no. he didn’t remember me at all, he just resd the name plate. I wish I had put“Irving”down on my name plate. If he’d have said,“Oh yes, Irving,how could I forget you?”I’d have been ready for him. There’snothing personal here.

　　The manager and everyone else who were a step above the box boys often shouted orders. One of these was:you couldn’t accept tips(小费)。Okay, I’m outside and I put the bags in the car. For a lot of people, the natural reaction(反应)is to take a quarter and give it to me. I’d say,‘‘I‘m sorry, I can’t,”they‘d get angry. When you give someone o tip, you’re sort of being polite. You take a quarter and you put it in their hand and you expect them to say,”Oh,thanks a lot.”When you say‘‘I’m sorry,I can’t.” They'd get angry.When you give someone a tip,you're sort of being polite.You take a quarter and you put it in their hand and yo cxpect them to say, "oh , thanks a lot." When you say,"I'm sorry,I can't,"they feel a little put down. They say "No one will know.”And they put it in your pocket. You say, "I really can’t.”It gets to a point where you almost have to hurt a person physically(身体上)to prevent him from tipping you. It was not in agreement with the store’s belief in being friendly. Accepting tips was a friendly thing and made the customer feel good. I just couldn’t understand the strangeness of some people’s ideas. One lady actually put it in my pocket, got in the car,and drove away. I would have had to throw the quarter at her or eaten it or something.

　　I had decided that one year was enough. Some people needed the job to stay alive and fed. I guess I had the means and could afford to hate it and give it up.

　　You are what you eat. This saying has provided scientists with clues(线索)about the diet of hominids- our early relatives of 3 million years ago.

　　Studying carbon atoms(碳原子)locked up in tooth enamel(珐琅质),two researchers argue against the widely held belief that hominids ate little more than fruits and leaves. Sponheimer and Julia Lee-Thorp of the University of Cape Town,South Africa, report their findings in Friday’s Science.

　　There aren’t many clues for us to know the life of early hominids. The shape of hominids’teeth offered the first clues. Large and flat-edged with thick enamel, they looked perfect for eating nuts and fruits, different from the sharp teeth one would want to tear into meat with. The first stone tools, which would help in eating meat, didn’t appear until about half a million years later.

　　Scientists have also found marks on hominids’teeth with patterns very similar to those on the teeth of modern-day fruit eaters. Sponheimer and Lee-Thorp tried a new method ,looking at the chemical composition of the tooth enamel.They studied the enamel for the carbon-13. Animals that eat grasses have higher carbon-13 levels than those eating fruits and other plants.

　　What they found was that the teeth to the hominids had an in-between amount of carbon-13, which meant not only they were eating fruits, they were eating a lot of grasses, or animals eating grasses. The lower carbon-13 levels could also come from eating certain types of insects (昆虫).

　　But there are people who understand differently. Prof. Ungar of the University of Arkansas agrees the study offers new suggestions of hominids diet, but disagrees about the suggestion that meat could explain the lower carbon-13 levels .

　　One suggestion might be true though-take good care of your teeth .In 3 million years,a scientist might be using them to figure out what you ate for dinner.

　　A. the shape of hominids' teeth

　　B. the teeth marks of early fruit eaters

　　C. the grasses of 3 million years ago

　　D. the make-up of the tooth enamel

　　67. What is it that Prof. Ungar finds doubtful?

　　B. Hominids probably had different diets.

　　C. Hominids were basically fruit- and grass-eaters.

　　D. Hominids had lower level of carbon-13 in the teeth.
