Hello, everyone! I'm Frank. I {#blank#}1{#/blank#} ten. I study (学习) at No.11 Middle School. Here is a photo {#blank#}2{#/blank#} my family. The man behind (在...后面) me is my father. His name is Dale Brown. He is{#blank#}3{#/blank#} teacher in my school. He teaches English. And this is my mother. She is a teacher, {#blank#}4{#/blank#}. These are my grandparents. {#blank#}5{#/blank#} is that woman next to (在...旁边) my grandmother? She is my {#blank#}6{#/blank#}, my father's sister. {#blank#}7{#/blank#} is a doctor. How {#blank#}8{#/blank#} the little girl? Oh, she is my sister, Lily. We {#blank#}9{#/blank#} a dog. It is in the picture, too. I love my family {#blank#}10{#/blank#} I love our dog, too.

It used to be that people would drink coffee or tea in the morning to pick them up and get them going for the day. Then cola drinks hit the market. With lots of caffeine and sugar, these drinks soon became the pick-me-up of choice for many adults and teenagers. Now drink companies are putting out so-called "energy drinks." These drinks have the specific aim of giving tired customers more energy.

One example of a popular energy drink is Red Bull. The company that puts out this drink has reported that Red Bull is not a thirst quencher (解渴饮料). Instead, the drink is meant to revitalize(使恢复生机) a tired customer's body and mind. In order to do this, the makers of Red Bull, and other energy drinks, typically add vitamins and certain chemicals to their drinks. The added chemicals are like chemicals that the body naturally produces for energy. The vitamins, chemicals, caffeine, and sugar found in these drinks all seem to give a person energy.

Health experts are not so sure, though. For one thing, there is not enough evidence(证据) to show that all of the vitamins added to energy drinks actually raise a person's energy level. Another problem is that there are so many things in the drinks. Nobody knows for sure how all of the ingredients in energy drinks work together.

Dr. Brent Bauer cautions (告诚) people about believing all the claims (申明) energy drinks make. He says, "It may be true if you put these twelve things together, you will get a good result." However Dr. Bauer adds the mix of ingredients could also have a negative impact (负面影响) on the body "We just don't know at this point," he says.
