Article: One cold morning in winter, I went alone to a hillside to do some hunting. I sat there waiting for about an hour. Suddenly, a big beautiful deer appeared less than 20 feet away from me. There was no cover near him. Surely I could shoot him. To my surprise, he came toward me! He was curious, I suppose, or maybe he was stupid. For this was not a youngster, but a fully grown-up one. He must have known about men and their guns. But this deer came closer, and I still waited. His big eyes never moved away from my face. His wonderful head with a set of antlers was clear in sight. I was getting a bit nervous as he walked closer. A big deer can do a lot of damage. Well, he walked right up to where I was sitting. Then he stopped and looked at me. What happened next was hard to believe. But it all seemed quite natural. I held out my hands and scratched his head right between the antlers. And he liked it. The big, wild, beautiful deer bent his head. I scratched and touched his head and body. His nose touched my shoulder. I fed him with my last sandwich. Well, he finally went his way, down the hill. Shoot him? Not me. You wouldn't, either. Not after that. I just watched him go, a strong deer carrying a proud head. I picked up my gun, and started walking back. Suddenly, I heard two shots, one after another. If you have hunted much, you will know what two shots mean. They mean a kill. I had forgotten that there were other hunters around. You will now understand why I gave up hunting from that day on. Question: After reading the whole passage, we can know that the passage is written in a(n) _ tone. Yes or no, is the answer "sad"?

Article: Americans are proud of their variety and individuality,yet they love and respect few things more than a uniform,whether it is the uniform of an elevator operator or the uniform of a fivestar general. Why are uniforms so popular in the United States? Among the arguments for uniforms,one of the first is that in the eyes of most people they look more professional than civilian clothes. People have become conditioned to expect superior quality from a man who wears a uniform. The television repairman who wears a uniform tends to inspire more trust than one who appears in civilian clothes. Faith in the skill of a garage mechanic is increased by a uniform. What easier way is there for a nurse,a policeman,a barber,or a waiter to lose professional identity than to step out of uniform? Uniforms also have many practical benefits. They save on other clothes. They save on laundry bills. They are taxdeductible .They are often more comfortable and more durable than civilian clothes. Primary among the arguments against uniforms is their lack of variety and the consequent loss of individuality experienced by people who must wear them. Though there are many types of uniforms,the wearer of any particular type is generally stuck with it,without change,until retirement. When people look alike,they tend to think,speak,and act similarly,on the job at least. Uniforms also give rise to some practical problems. Though they are longlasting,often their initial expense is greater than the cost of civilian clothes. Some uniforms are also expensive to maintain(,),requiring professional dry cleaning rather than the home laundering possible with many types of civilian clothes. Question: The best title for this passage would be _ . Yes or no, is the answer "Advantages and Disadvantages of Uniforms"?
No

Article: Can you smell two things at once? This experiment comes from the research of two scientists from Rice University. Denise Chen and Wen Zhou have been experimenting with the science of smell, and have made some very interesting discoveries. To explore that, you will need two things with strong, characteristic smells and, of course, your nose. The idea is to smell a different smell with each nostril . Hold one smell very close to your right nostril, and the other smell very close to your left nostril. Then breathe in and pay close attention to what you smell. What you should find is that one smell will be very strong. After another sniff or two, the first smell will go away, and you will smell the other smell. Keep sniffing, and the first smell will come back. Instead of smelling the two smells evenly mixed, they will work in turns, one after the other. Why? Chen and Zhou found that your sense of smell acts much like your sense of sight. Hold a book in front of your nose, so that your left eye sees things on the left side of the book, and your right eye sees things on the right side of the book. You will find that your sight works in turns, first on the left side of the book and then on the right side. Notice that you can't focus your left eye on one object while focusing your right eye on another object. Your brain jumps back and forth , paying attention to one and then the other. The same thing happens with your nostrils. If they are smelling different smells, your brain pays attention to one and then the other. Question: Denise Chen and Wen Zhou discovered that _ . Yes or no, is the answer "our brain focuses on one thing at a time"?
No
