Article: Imagine that the genome is a book.The book consists of 23 chapters with thousands of stories made up of paragraphs, words and letters on different levels.There are one billion words in the book, as long as 800 Bibles; if I read the genome out to you at the rate of one word per second for eight hours a day, it would take me centuries; if I wrote out the human genome, one letter per millimeter, my text would be as long as the River Danube.This is a huge volume, a book of great length, but it all fits inside an extremely small cell nuclear that fits easily upon the head of a pin. The idea of the genome as a book is not, strictly speaking, even a metaphor.It is true to a great extent.A book is a piece of digital information, written in one-directional form and defined by a code that translates a small alphabet of signs into a large dictionary of meanings through the order of their groupings.So is a genome.The only difference is that all English books read from left to right, while some parts of the genome read from left to right while some from right to left, but never both at the same time. While English books are written in words of different lengthens using twenty-six letters, genomes are written entirely in words of three-letter length, using only four letters, and instead of being written on flat pages, they are written on long chains of DNA molecules . The genome is a very clever book, because in the right condition it can both photocopy itself and read itself. Question: We can learn from the passage that the human genome _ . Options: A: is as long as the River Danube B: can be easily placed on the head of a pin C: is coded with an alphabet of four letters D: is smart enough to read and take photos of itself
C

She was not sure what gave her the idea, but she wanted to look like a movie star. "I have a lot of pictures from my childhood of me wearing sunglasses," she says. "I used to wear them to watch TV." Early movie actors started wearing sunglasses not because they looked good, but because their eyes hurt. The lights used on movie sets were extremely bright and could cause a painful problem known as "Klieg eyes". It was named after the Klieg brothers who invented the lights. Actors wore sunglasses to give their eyes a rest. But when movie stars began wearing their sunglasses in public, they quickly became a must. Eventually actors started wearing sunglasses in their movies as well as on the street. Audrey Hephburn wore ultra-cool Ray-Ban sunglasses in the 1961 movie, Breakfast at Tiffany's. As a result, Ray-Ban sunglasses started to appear more and more in the movies. In 1979, Ray-Ban "Wayfarers" were worn by Jake and Elwood in The Blue Brothers. Tom Cruise wore Ray-Ban "Aviator" sunglasses in the 1986 hit, Top Gun. Then in 1997, Will Smith and Tommy Lee Jones made Ray-Ban "Predator" sunglasses famous in Men in Black. Of course sunglasses aren't just a fashion statement. The main reason to wear sunglasses is to protect our eyes against UV radiation. UV radiation can damage our eyes, so people now choose their sunglasses carefully. But you don't have to give up style for safety. The choice of frames and lenses available these days is huge. So you can protect your eyes and still be the coolest person on the beach. Question: Now people wear sunglasses _ . Options: A: for fashion and to protect their eyes B: just to protect their eyes C: because of bright lights D: because movie stars wear them

Q: Read the article and select the best answer. Article: I was going to Paris, which I'd always wanted to see. But now I was frightened to travel alone. I arrived at the train station in Paris. I hadn't spoken my college French for twenty years. On my first metro ride, I came across an incompetent thief. I just stared at him, and he stopped his hand from my purse and disappeared into the crowd. Somewhere in this confusing city was my hotel hidden, but the directions suddenly weren't easy to find. When I finally found the hotel, my heart was beating heavily, and I was sweating like a basketball player. I couldn't stay. Could I? The wallpaper looked like it had been through a fire. The bathroom was downstairs, and the window looked out onto the brick wall of another building. Welcome to Paris. I sincerely wanted to die. I missed my friends. I was entering my third week away from home and my kids, and I had arrived in the most romantic city in the world, alone, lonely and frightened. The most important thing I did in Paris happened at that moment. I knew that if I didn't go out, right then, and find a place to have dinner, I would hide in this small room my entire time in Paris. I might never learn to enjoy the world as a single individual. So I went out. Evening in Paris was light and pleasant. I walked along a path, listening to birds sing, watching children float toy boats in a huge fountain. No one seemed to be in a hurry. Paris was beautiful. And I was here alone and suddenly not lonely. My sense of accomplishment overcoming my fear and weakness had left me feeling free. I wore out two pairs of shoes during my week's stay in Paris. I did everything there was to do, and it was the greatest week of my European vacation. I returned home, becoming a believer in the power of traveling alone. Now when I meet difficulties I just say to myself, "If I can go to Paris, I can go anywhere." Question: The lifestyle of French people can be considered as _ .
