There's a whole lot of things that people fill their stomachs with. Some of them keep people alive. Some of them taste good to people. Some of them help people win pie-eating contests. Alcohol does none of these things. Why do people keep drinking it? And what does it do once it gets to their stomachs? There are all kinds of alcohol molecules  , but the one that people most often pour down their throat is ethanol  . Ethanol is very tiny and it dissolves in water, so it gets into all sorts of places that it's not supposed to. Alcohol heads for the digestive system. Because it dissolves in water, it can get into the water in the bloodstream. Because ethanol, to a certain extent, can pass through cell membranes . It can go almost anywhere. It spreads through the muscles, and is sweated -- unmetabolized  and whole -- through the skin. It gets into the heart. It even takes a walk through the brain, and this is the secret of its powers. Alcohol depresses the nerves, and the nerves affect almost every area of the body. Enough alcohol makes people sleep, so people who become unconscious choke on their own vomit  . Most worryingly, enough alcohol can shut down those parts of the brain just like any other parts. People become unconscious and their brains simply forget to breathe. Alcohol is broken down in the liver. Alcohol doesn't destroy the liver, but products that the liver breaks the alcohol into do cause damage. A glass of wine per day can not do any harm. Instead, it can prevent heart attacks or can make someone functionally young. And it is kind of nice to know that sometimes, relaxation and cheer can be bottled. All that's needed is to take care how much alcohol is let into a person's brain. How does the author introduce the topic of the text? A) By statement. B) By question. C) By arguing. D) By explaining.

On Monday night, back on the way home from school, I was suddenly faced with a big snow storm which I had never met before. The traffic was moving at 5 mph on the freeway where it usually requires at least 60 mph. The road is very slippery. Sometimes the car is out of control, slipping to the other side. I finally managed to drive to the Issaquah. However, I still got stuck in the traffic on an uphill way to my home. Why I lived in the house on the top of the hill? I had no choice but left my car in the road. Fortunately, there was a nice guy coming to help me drive the car to the parking lot so that I would not get a ticket from the policeman. When he first opened my car door and asked me if I needed any help, I thought I saw an angle. No kidding, I was totally frustrated at that moment until I saw the guy. After waiting in the parking lot for almost 3 hours, my husband's cousin finally managed to come to "rescue" me by his four-wheel drive car and sent me to my in-laws' home because the road to my house was closed. When I got to my bed in the end, it was over midnight. I spent almost 5 hours outside instead of 20 minutes as usual. But I was lucky, because I knew later that some people spent 7 or 10 hours to go home, and just by walking rather than by driving. This strong snow storm has messed up the traffic of Seattle and I get an unforgettable experience from it. From the passage we can know that the author   _  . A) was almost stuck in the traffic B) was almost fined   by the police C) could drive as fast as 60 mph at most D) had her car slipped into the other side

Last night, on my way home I stopped because of being attracted by some hamburgers at a fast food restaurant. On my way in, a homeless man approached me and asked, "Do you have any bottles lying around?" I knew he would recycle them for a few cents, but I didn't have any, so I said no. And again he asked, "Can you spare some change ?" I smiled, and said no again. He was very respectful; he smiled back and said, "OK, thank you." Even though he didn't have anything, he was still in good spirits. From the way he spoke I could tell he was smart. Then I bought one hamburger and enjoyed my meal, but in the back of my mind I wondered whether the homeless man was hungry. After I finished my meal I decided to order another one for him. At this point I didn't know if he was still around, but I tried anyway. At the counter I ordered a hamburger and also a hot chocolate, because it was cold outside, and I thought it would help warm him up. They delivered me the hot chocolate first and as I waited for my hamburger, I noticed the homeless man was standing right beside me. I looked at him and smiled, "This hot chocolate is for you." He replied like a gentleman, "Thank you so much. That's very kind of you." I always believe no matter how _ I am, there are always those who are worse off than I. When you help someone, it's not always about money, it's about love. The love you give today, someone might forget tomorrow. It doesn't matter. Love anyway, because the greatest thing you can give is love. The author wants to tell us that   _  . A) love cannot be forced B) money cannot buy everything C) there is always someone that we can help D) we shouldn't forget those who once helped us

I believe I've gotten this more than once. One lady told me she thought I was 12 and even told her 14-year-old daughter the same. I saw lots of surprised faces because people were told I was actually 19 years old. I'm actually 19 years old, which isn't much of a problem. I'm like the oldest of my friends and the shortest, which is pretty funny. That's probably one of the reasons I fit in so well with them. I volunteered at a weekend school teaching young children. Parents always looked me up and down like "why is this 13-year-old girl teaching my child?!??!?" I guessed it was because I'm also petite ,and I didn't know whether I had a childish face...??? Sometimes I found it funny, sometimes I found it annoying . But I just shrugged it off at last. You know, soon enough people got to know me and then realized I was not actually a 13-year-old girl. This short thing used to be a problem for me, though. I was very very small when I was younger, so kids would  _ me. When I was 12, 8-year-old girls would look down at me like "I CAN'TBELIEVEYOU'RETWELVE!" I had always wanted to be tall. But now that I'm older, I got used to it, and I actually love it. You know, I'm fun sized! Which of the following words can't be used to describe  the writer? A) short B) petite C) childish D) tall
