I'm taking a test and have to guess the right answer to the question after the article. Article: One Sunday, I took my daughter to the seaside. On arriving at the beach, I saw JoJo, a wealthy man in hotel business. We sat down to chat in an open air cafe while I watched my daughter enjoy herself on the swings   in front of us. Suddenly, our conversation was interrupted by a stranger, who politely asked permission to speak to me privately. People often want to tell me something about my TV show. We stood a bit away from my table. He said, "I'm James, the father of a 7-year-old girl who's very sick. The doctors said that if she was treated in the UK, she would probably survive. But I'm poor, so can you help me, please?" I stared into the man's eyes full of tears and asked how I could help. After I went back, JoJo asked me, "What's wrong?" I told him about it and he was very sorry for that family. All day I thought about James's family. I even thought about making a special TV show to raise money for the sick child. On Monday morning, JoJo walked into my office. Actually, JoJo was very busy, and I never imagined he would have the time to come and see me. "Please, call the man and tell him I'll pay all the expenses for the girl's treatment," JoJo said with a cheque in his hand. "I've been married for 35 years; I wasn't lucky enough to have a child. Sometimes I feel lonely. I want to help this child." I picked up the phone to call James. Now James's daughter is well and JoJo sometimes goes to visit her. I'm so happy that there are so good people on this earth. Question: James turned to the writer for help probably because he   _  . Options: A: guessed the writer was rich enough to help him B: wanted the writer to ask JoJo for help C: thought the writer could help him through TV D: knew the writer was warm-hearted

I'm taking a test and have to guess the right answer to the question after the article. Article: The speed of light is often called a"constant ". New experiments show that may not be true, even within a vacuum. Sometimes, light slows a bit. The new research is"very impressive work", Robert Boyd toldScienceNews.An optical physicist at the University of Rochester in New York, he did not work on the study. He speaks of the new finding:"It's the sort of thing that's so obvious; you wonder why you didn't think of it first." Light travels as particles and as waves. Photons are the name given to those particles that represent the smallest possible amount of light. At their fastest, photons travel nearly 300 million meters (almost 1 billion feet) in a single second. That's fast enough to get to the moon and back in about 2.6 seconds. Scientists had long known, though, that they could slow light photons down by shining them through a material such as glass or water. Still, light moving through a vacuum has usually been assumed to move at a peak speed. That would seem to make sense. After all, a vacuum is a space with nothing in it to slow light down. In a new study, however, scientists show that even racing through a vacuum, light can slow. So the speed of light is more of a universal speed limit than an   rule for how fast photons travel, the new data suggest. Miles Padgett led the new study. As an optical physicist, he works at the University of Glasgow in Scotland. He and his colleagues showed that the key to slowing light is to change the shape of a light wave. Padgett described how they did this in a paper published online January 22 inScience. His team raced a pair of photons. One traveled unchanged through a cable made from optical fibers. The other passed through a pair of devices that acted like lenses. A lens changes light: It can focus a spread-out beam of light on a point, for instance. The second photon passed through one device that changed the shape of its waveand another that changed it back to its original form. The first photon won the race. The second photon came in a tiny bit later, several... Question: The most important factor in changing the speed of light is to transform    . Options: A: the shape of a light wave B: the length of a light wave C: the direction of a photon D: the structure of a photon

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: How to Study Smarter, Not Harder Here are some of our favorite study tips that will help any student study smarter, not harder: Recite As You Study Reciting--saying things out loud should first take place as you read through each paragraph or section. Test yourself. This will help you to understand as well as learn faster because it is more active than reading or listening. It will also help you to notice your mistakes and the topics you have trouble understanding. Take Fuller Notes Notes should be in your own words, brief and clear. They should be tidy and easy to read. Writing notes will help you better than just underlining as you read, since it forces you to rewrite ideas in your own words. Study the Middle The best time to review is soon after you've learned something. You are more likely to remember the material at the beginning and the end of the lesson, so make sure you focus on the middle when you review. Sleep On It Study before going to bed, unless you are very tired. It's easier to remember material you've just learned after sleeping than after an equal period of daytime activity, because your brain continues to think even after you've fallen asleep. Combine Memory and Understanding There are two ways to remember: by memorizing and by understanding. Multiplication tables, telephone numbers, and math formulas are better learned by rote. Ideas are best learned by understanding. The more ways you have to think about an idea, the more meaning it will have; the more meaningful the learning, the better you can remember it. Pay attention to similarities in ideas and concepts, and then try to understand how they fit in with things you already know. Never be satisfied with anything less than a completely clear understanding of what you are reading. If you are not able to follow the thought, go back to the place where you first got confused and try again. Question: You can notice your mistakes by   _  . Options: A: saying things out aloud B: taking notes C: studying the middle D: sleeping on it
A: A
Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Before 1900, many theories existed as to the cause of yellow fever  . Some doctors were sure the disease was air-borne; others felt that it was spread from person to person. Dr. Carlos Finlay, a well-known Cuban doctor of that time, had long held the theory that it was caused by the bite of mosquitoes. But neither the public nor the doctors then accepted his idea.    Walter Reed,all American doctor sent to study yellow fever in Cuba,went to talk with Finlay.Reed,after reading a lot on the subject,had begun to think that Dr.Finlay might be fight.Then Reed and his comrades set to work at once.Outside Havana,they set up a laboratory and began experiments to test the theory.The experiments were successful.Now we know:A period of about two weeks must pass before a mosquito,after feeding on a sick person,could infect  another person.The sick person had to have yellow fever a certain number of days before the mosquito biting him was able to carry the disease. Question: Reed proved the theory  _  . Options: A: in his American lab B: by talking with Finlay C: in a kind of scientific Way D: by reading a lot of articles
