Ques:Nowadays, the food we eat seems to have great effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, about 68 years ago, government researchers realized that nitrates, commonly used to preserve color in meats, and other food additives, caused cancer. Yet, these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to beef and living animals, and because of this, penicillin has been found in the milk of treated cow. Sometimes similar drugs are given to animals not for medical purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue. Which of the following statements is NOT true? A) Drugs are always given to animals for medical reasons B) Some of the additives in our food are added to the food itself and some are given to the living animals C) Researchers have known about the potential dangers of food additives for over thirty-five years. D) Food may cause forty percent of cancer in world.

Ques:After sunset on our last day at the farm I walked out into the desert. In this, the first pleasant moment for a walk after long hot hours, I thought I was the only thing out of doors. Suddenly I stopped. Before me a rattlesnake lay fixed, its head not yet drawn back to strike but only turned a little to watch what I would do. Many snakes will run away at the sight of a man but this rattlesnake felt no necessity to get out of any-body's way. He held his ground in calm watch-fullness waiting for me to show my intentions. My first aim was to take no notice of him; I had never killed an animal if I was not forced to kill. But I remembered that there were children, dogs and horses at the farm as well as men and women with thin clothes on; my duty was to kill the snake. I went back to the farm and returned with a stick. The rattlesnake had not moved; he lay like a wire but more quickly than I could stride he shot into a bush and set up his rattling, warning me by this that I had made an unreasonable attack and attempted to take his life and that if I insisted he would have no choice but to take mine if he could. For a moment I listened to this terrifying sound and then I struck into the bush with my stick and, chop-ping about, dragged him out of the bush with his back broken. He struck once more at the stick but a moment later his neck was broken and he was soon dead although  when I picked him up by the tail his mouth opened, proving that a dead snake may still bite. There was blood in his mouth and poison was dropping; it was not only a dis-gusting  sight but a pitiful one too. I dropped the body into a green bush and, as I did so, I saw him in my imagination, crawling over the sands as he might have done if I had let him go. The author had to kill the rattlesnake because_. A) it stood in his way B) it attempted to take his life C) it presented a disgusting sight D) its presence was a danger to the people and animals at the farm

Ques:Being less than perfectly well-dressed in a business setting can result in a feeling of great discomfort that may well require treatment to eliminate (remove). And the sad truth is that "clothing mismatches" on the job can ruin the day of the person who is wearing the inappropriate attire --and the people with whom he or she comes in contact. Offices vary when it comes to dress codes. Some businesses have very high standards for their employees and set strict guidelines for office attire, while others maintain a more relaxed attitude. However, it is always important to remember that no matter what your company's attitude is regarding what you wear, you are working in a business environment and you should dress properly. Certain items may be more appropriate for evening wear than for a business meeting, just as shorts and a T-shirt are better suited for the beach than for an office environment. Your attire should reflect both your environment and your position. A senior vice president has a different image to maintain than that of a secretary or sales assistant. Like it or not, you will be judged by your personal appearance. This is never more apparent than on _ , when what you wear can say more about you than any business suit ever could. In fact, people will pay more attention to what you wear on dress-down days than on "business professional" days. Thus, when dressing in "business casual" clothes, try to put some good taste into your wardrobe choices, and recognize that the "real" definition of business casual is to dress just one notch  down from what you would normally wear of business-professional attire days. Remember, there are borders between your career and our social life. You should dress one way for play and another way when you mean business. Always ask yourself where you are going and how other people will be dressed when you get there. Is the final destination the opera, the beach, or the office? Dress properly and you will discover the truth in the principle that clothes make the man--and the... Which of the following statements is true? A) Every company has strict rules regarding office dress. B) You can wear whatever you like if your company doesn't have high standards for it. C) You should dress according to the business setting even when there are no fixed rules. D) In companies with relaxed rules on office dress, you can't spot a manager among others.

Ques:It seems hard to watch someone yawn  and not to yawn ourselves. Even reading about yawning can make you do it. Now, a new study has found why yawning has such a powerful force. Yawning when others yawn, the study suggests, is a sign of pity and a form of social connection. Kids don't develop this deeply rooted behavior until around age four, the study found. Kids with autism   are less likely to catch yawns. In the most serious cases, they never do. Yawning might help doctors to see whether the children are developing rightly. The work could also lead to a better understanding of the ways that people communicate and connect. "Emotional infection seems to be a born thing that connects us together," said Molly Helt, a graduate student in psychology at the University of Connecticut. "Yawning may be part of that." Inspiration for her study came when she tried to get her own autistic son to clear his ears on an airplane. She repeatedly yawned at him, hoping he would yawn back. He never did. "The fact that autistic kids don't do it might mean they're really missing out on that emotional connection with people around them," she said. "The biggest thing people try to figure out after birth is how we become humans and understand that humans have minds that are different from others'," she added. "Autistic people never seem to understand that." Like infectious  laughter and crying, scientists have found that yawning is a shared experience that promotes social connection. Helt said it could fight stress after a period of being nervous and spread a feeling of calm through a group. Which of the following is NOT true about yawning? A) It is natural to yawn back if people around you yawn. B) Some kids are too young to yawn after others. C) Yawning can be used to test children's development. D) Kids with autism yawn easily when others yawn.
