A new study indicates that dog ownership specifically may be one of the biggest single contributors to what kinds of microbes live on your skin. A team of researchers led by Se Jin Song at the University of Colorado, Boulder, took swabs of the tongues, palms, forehead and feces of members of 60 family households. Some of the families had children or household pets and some did not; dogs were the only pets swabbed. Researchers then analyzed the DNA of the bacteria they found to determine how diverse the bacteria populations were. Not surprisingly, family members who lived together had more bacteria in common than members of separate households. Bacteria on the skin were especially similar within households, probably because we pass microbes through the air, through direct contact, and via the surfaces we touch. The most surprising finding, however, was the large bacteria contribution Fidonad made. The skin bacteria of dog owners from different households was almost as similar as if they'd cohabited without a dog. Put another way, you and a friend across town who both own dogs share a skin ecosystem as alike as a married couple does. The reason for this appears to be that dogs harbor some kinds of bacteria that are rare on human skin. One in particular, a family of bacteria called Methylophilaceae, was abundant in the mouths of dogs sampled as well as the skin of their owners--indicating "a common occurrence of oral-skin transfer between dogs and their owners," according to the results published in the journal eLife. Question: If both you and your friend who live on the other end of your neighborhood have dogs, you may probably _ . Options: A: have lived together without a dog. B: share similar skin ecosystem. C: be married couples before. D: shared the same dog.

Aaron Puzey had been on his exercise bike for half an hour a day for years when he decided to look for a way to make it a bit more fun. With virtual reality technology widely available nowadays, all be needed to do was find a way of applying it to his needs. So he set out to build an app for the Samsung Galaxy Gear VR headset which would allow him to hook it up to Google Street view and make it seem like he's cycling through different real-life locations. Building the app to download the 3D data from Street View and make it viewable in the VR headset was the toughest part of his project. Other than that, all he needed to do was tape a Bluetooth monitor to his exercise bike. Although the quality of the images sometimes leaves a lot to be desired,leaving complex scenes like trees looking like a mess,Aaron has been having a lot of fun on his journey. Aaron's project is obviously no substitute (> for real outdoor cycling as it Lacks things like the wind blowing in your face or the pain of battling an uphill climb, bul it has given him a goal, as well as the chance to take in the beauty of places he might have otherwise never seen. It definitely beats staring at a wall or at the TV for 30 minutes, anyway. Obviously, Aaron's setup theoretically allows him to ride a bike anywhere around the world. He says he ba6 always wanted to see Japan, so once his ride comes to an end, he plans to start another one across the Land of the Rising Sun. Question: Which of the fallowing can best describe Aaron Puxey? Options: A: Creative. B: Ambitious. C: Funny. D: Boring.

Ques: Read the article and select the best answer. Article: Recently, tests have proved that Beethoven died from lead poisoning. Bill Walsh directed the Beethoven Research Project. Mr Walsh and his team examined pieces of bone belonging to Beethoven. They found a large amount of lead in the bone pieces. They said the lead levels were equal to those found in pieces of his hair in earlier studies of other scientists. Genetic tests proved the bone pieces and hair came from Beethoven. The researchers also examined bone fragments( from someone else who lived during the same period. Both were from the top of the skull. The fragments from Beethoven had more lead than those from the other person. Their study didn't find measurable levels of cadmium or mercury , which scientists used to consider were the causes of his health problems. Beethoven was sick for much of his life. He experienced strong stomach pains, a sign of lead poisoning, and a change of personality when he was around 20. He also got angry easily, and suffered from depression and hearing loss. His health problems became worse as Beethoven grew older. Walsh said the lead levels found in Beethoven's skull suggested the metal might have been present in his body for many years. He said although there had been recognized cases of deafness caused by lead poisoning, there was no strong evidence to suggest that lead poisoning was the cause of Beethoven's deafness. Ludwig van Beethoven visited many doctors to find a cure for his health problems. In a letter he wrote to a friend, he asked researchers to examine his body after he died so that other people would not have to suffer as he did. Question: From the passage, we can learn that _ . Options: A: this is the first research into the cause of Beethoven's death B: any amount of lead will do great harm to people's health C: more lead was found in Beethoven's bones than in his hair D: scientists used to think that Beethoven's death was caused by other metals instead of lead

Question: Read the article and select the best answer. Article: I liked most of my teachers in college. They were, for the most part, friendly and competent, willing to help students. I liked them--but I don't remember them very well, except for Mr. Jones, my senior English teacher. He was an enthusiastic, sensitive man, who knew his subject and was determined that we would learn it and love it, too. Mr. Jones was a tall, slim man in his midforties. Put precariously on his nose, his glasses gave him a serious look. But they didn't remain there long, for he was always taking them off and polishing them and putting them in his mouth when he thought over a response to a student's question. When he walked into class, he was always carrying two or three books with strips of paper sticking out of them, marking passages he planned to read. I remember, too, the cardigan sweaters--he must have had a dozen of them. On rainy days he substituted a blue raincoat for the sweater. But what I remember best was his smile. When he smiled, his whole face lit up. His smile made you feel good, at ease. Yet though he was friendly with people, he was a bit formal in class, and he could be firm on occasion. He never called us by our first names. He obviously loved his work and liked his students, but he kept his distance. He never deliberately embarrassed a student in front of the class with an ironic remark, but he could communicate his displeasure all right. He'd look steadily at the offending student for a few seconds. That was usually enough, but if it didn't work, he'd say something to the student in a lowered tone of voice. He didn't do this often, though. Mr. Jones' personality and passion made him popular, but what I liked most about him was that he was a fine teacher. Yes, he cared about students, but he cared more about teaching them his subject. And that meant homework, lots of it, and pop quizzes now and then to keep them reading. He lectured occasionally to provide background information whenever we moved on to a new literary period. After a brief glance at his notes, he'd begin... Question: Which of the following words can be used to describe Mr. Jones? Options: A: Smart and honest. B: Confident and stubborn. C: Hardworking and modest. D: Responsible and friendly.
