Don't blame genes for aging facial skin. A new study of twins suggests you can 1 those coarse(粗糙的) wrinkles, brown or pink spots, and dilated(膨胀的) blood vessels on too much time in the sun, smoking, and being overweight.

Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is 4 more to environment and lifestyle than 5 factors.

Baron's team 8 facial skin of 130 twins, 18 to 77 years old, who lived 9 in the northern Midwest and Eastern regions of the U.S. who were 10 the Twins Days Festival in Ohio in August 2002.
At this time, each of the twins also 11 reported how their skin burned or tanned 12 sunscreen(防晒霜), their weight, and their history of skin cancer, smoking, and alcohol drinking.
The study group 13 of 52 fraternal and 10 identical twin pairs, plus 3 pairs who were unsure of their twin status. Identical(同卵的) twins share all of their genes and fraternal twins share only about half.
From these data, the researchers 14 strong ties, outside of twin status, between smoking, older age, and being overweight, and having facial skin with evidence of environmental 15

One day I was walking to the mailbox with my dad，when I saw something drop from a tree.I couldn't what it was,so I kept my eyes on the spot as we came near .It was a baby bird,which had fallen from its nest.It had long,awkward wings and feet,and that fought to stay open .It was , so I sat next to it watching while my dad got the mail.I its nest and mother , what would happen to it.
My dad and we had to it;there was nothing we could do.He said if the bird mother smelled any traces(踪迹) of ,she wouldn't go near the again.
As we began to walk away,a woman .”Did it fall out of a nest ?”she asked.
“Yeah.”I answered.
“It a lot. Not much we can do,”she said .”Try not to think about it when you go to sleep tonight.”
I walked the mailbox the next day.The baby bird lay in the grass.
I realize that “Try not to think about it” is the of many people towards things which to provide them with perfect excuses not bothering . The woman wasn't being ; she was actually quite nice. But when everyone says”there's I can do —just try not to think about it，”Where will we finally ? When billions of people try not to think about it When they go to bed at night, there might be millions of fallen birds lying dead and in the grass the next morning.

阅读下面短文,从短文后各题所给的四个选项(A、 B、C 和 D)中,选出可以填入空白处的最佳选项,并在答题卡上将该项涂黑。
I loved working with my dad, but I hated a summer job he gave me. He owned a small in Bank Street. In his shop, the most recently person got the worst job, and the boss’ son was also .
I didn’t want to spend hours the frost on the ceiling of the walk-in freezer, and it was the Saturday afternoon’s job that I hated most. We received fresh every day. Chicken sat in wooden boxes and was with crushed ice. During the week, the ice and the blood of the chicken slowly leaked into the container the chicken, creating its bloody smell.
There was only one to get rid of the blood and wash the container: hold my and carefully slide the container from under the chicken, as I tried not to the contents over my clothes, and then into the drain(下水道).
Soon, students who have cut lawns, painted houses, worked in offices, maybe even worked in the butcher’s will to school. Some will have great memories others will come back with ones.
Looking back, I think my father could have me from my weekly hell. However, my dad, who’d dropped out of school to help support his family after his father died, was a teacher for me . He knew treating me from his other employees would be an unfair thing. Most importantly, he taught me to those who do the hard and tasks in life.
For the next six summers, I returned not as the boss’ son, but as one of other guys, and I cleaned the dirty container every Saturday afternoon.

What is real success? I am sure many would come up with answers like lots of money, a big house, a new car, and so on.
It has been interesting to see how my own idea of success has through the years. When I was young, I was eagerly reaching for material success. I chose my jobs accordingly and ended up in . Sure enough, I did earn some pretty good pay checks.
But then a different feeling started to . I began to realize selling was not what I wanted to do all my life. After all I was often forced to sell products that did not really suit customers. All that matters is the amount of money that is made. I became very unhappy.
I came to realize that even with big pay checks I did not feel successful. That is when my search for success turned inwards, I sales and chose another profession–helping people. The feeling of relief and belonging was great–and suddenly I felt successful again. Even though I earned than before, I was much more content.
Then I returned to my old love–writing.
I realized I felt most successful when I loved what I did never the money. Then for my own I define success by the feeling of contentment.
Always remember–you are not here to anyone else’s life but your own. It is not your obligation (义务) to please others with your life – only yourself, because only if you are happy yourself can you happiness to others. You cannot give what you do not have.
So be true to yourself and your own joyful path to your own of success.
