Q: If someone asks you, "What colour is the sky?" I think you will answer "blue". I'm afraid that you will be wrong. The sky has no colour. It looks blue because we are looking at the blue sunlight. The sunlight is shining on little bits of dust in the air. Is the sky full of air? I'm sure that you have asked this question, too. We know that there is air all around the world, but we couldn't fly very high because as we go high, the air gets thinner. If we go far enough away from the earth, we find there is no air. Maybe we can answer some questions now. What is the sky? Where is it? It is all round the world. The sky is space . In space there is nothing, but only the sun, the moon, the earth and all the other stars. The sky is _ . A) a star round the earth B) a big ball with air C) full of dust D) space with the sun, the moon, the earth and many other stars

Q: It was a great day for American girl D' Zhana Simmons when she got a new heart. However, her dream died when the new heart started not to work properly. The doctors had to take it away. She needed another heart transplant . But the doctors couldn't find a proper heart so soon. Then they came up with an idea -- they would use two machines to keep her blood _ in her body. After waiting for about four months, D' Zhana had another heart transplant. It was very successful. When doctors use a man-made heart to keep a patient's life, they usually leave the patient's own heart in the body. "She, we believe, is possibly one of the youngest that had the machines without her own heart," one of D' Zhana Simmons' doctors said. Living without a heart for 118 days -- that's great. When a heart transplant doesn't work, doctors have no time to waste. If they don't get a new heart or some machines to help the patient, he or she will die. The patient's life is in their hands. This story once again shows how important the medical world really can be. I hope that one day I will be a doctor. I hope I can be so quick and helpful to my patients. Which of the following is true according to the passage? A) D' Zhana Simmons had only one heart transplant. B) The doctors used two machines to keep D' Zhana Simmons' life. C) D' Zhana Simmons was the first person to live with a man-made heart. D) The doctors wasted some time when they looked for a heart for D' Zhana Simmons.

Q: In April, 2013, I visited Yangzhou. Ge Garden is very beautiful and peaceful. The ticket has a map on the back of it that I didn't noticed until I had already left. But to be honest, I don't think that map is very useful because it isn't very clear an tailed. In my opinion, it's better to improve it. Compared with He Garden, the map on the back of the ticket for He Garden is much clearer, more detailed and more useful. However, in the room that has the picture of the family members, there is only Chinese, no English, so my advice is to add English in interesting places. I got lost in the Slender West Lake. I spent about 30 minutes just trying to get out of one area. I think they need more signs posted along the trails. I like the Slender West Lake best, as she is so pretty! The ladies that were sweeping were very sweet. They always smiled at me and said hello, so it was nice. Taking a taxi is the most efficient and quickest way to get around Yangzhou. I didn't have a problem getting to the places which I'd like to go to while using a taxi. The driver was very friendly. The fare isn't too high, either. But I didn't enjoy taking the bus. The bus ride to the Mastixia Bay took long although I only had to pay one yuan. It was also hard finding where Bus 32 was. I tried asking some people in English but they couldn't understand me, so I had to ask in simple Chinese that I only know buy that still didn't work. I spent about one hour walking around the city to look for Bus 32. The tricycle was nice, but it was a little too expensive for a small distance. Maybe I was _ by the guy who rode for me, but it was an enjoyable ride. I felt like I was part of the garden city more. Over all I am satisfied with Yangzhou and will recommend it to others. We can infer the passage may be written by _ . A) a foreign visitor B) a lady sweeping in the park C) a taxi driver D) a guy riding a tricycle
