It was a voice of Scrooges nephew, who came upon the old man so quickly that he gave the latter quite a 1 .His nephew had so heated himself with rapid walking in the fog and frost that he was _2_ and gasping for breath. His handsome face was red and cheerful and his bright, dark eyes sparkled. The young man was obviously in a cheerful 3 . Scrooge was 4 by the cheerful face before him. He turned to his nephew and said, “Bah! Could you stop this nonsense of yours?”“Christmas a nonsense, Uncle!” said Scrooges nephew. “You dont really mean that, do you?”“Oh, yes, I do,” said Scrooge. “Merry Christmas! What right have you to be merry? Youre so _5 that I cant see any reason for you to be happy. I would be miserable if I were you.”“Come on, Uncle Scrooge, do stop 6 ,” replied the nephew gaily. “What right have you to be unhappy and sad? What reason have you to be so 7 and angry when one is as rich as you are?”Scrooge could not think of an answer at that moment. He was at a loss for 8 and all he could say was Bah again and follow that with What nonsense!“Dont be 9 , Uncle!” said the nephew.“What else can I be,” return the uncle, “when I live in such a world of 10 as this? Merry Christmas! Down with Merry Christmas! Whats Christmas time for you but a time for trying to pay 11 without enough money; a time for finding yourself a year 12 , but not an hour richer; a time to look back at the things you did, but only to realize that youve achieved _13 ?

This is not an act of egotism. It is their countrys way of honoring those 17 helped save Russia, even though 20 million Russians _18_(kill) by the Nazis. I went up to this old man 19 (sit) with his wife and said, “Druzhba i mir” (friendship and peace). The man looking at me as if in 20 (believe), took the button we 21 (make) for the trip and said “Friendship” in being held by loving hands, and said, “Americanski?” I replied, “Da, Americanski. Druzhba i mir.” He clasped both my hands as if we were long 22 (lose) brothers and repeated again, “Americanski!” This time there was recognition and love in his statement.For 23 next few minutes he and his wife spoke 24 Russian as if I understood every word, and I spoke English as if I knew he would understand. You know what? 25 of us understood a word, but we surely understood each other. We hugged, and laughed and cried, all the while saying, “Druzhba i mir, Americanski.” “I love you, I am proud to be in your country, we do not want war.

You opened the refrigerator, saw some left-over chicken, and ate it quickly. Several hours later, you felt very sick. Your stomach was painful and felt as if it had turned to liquid. You had to make frequent visits to the washroom. You felt unwell for several days and after you recovered, you thought to yourself “It must have been something I ate.” You were probably right.“Food poisoning” is the name given to the unpleasant symptoms you get when you eat food which is contaminated with certain types of harmful bacteria or by the poison produced by some bacteria. Contrary to popular belief, the bacteria which cause food to rot are not the most common cause of food poisoning. In fact, food poisoning from this cause is very rare simply because people do not usually eat food which is noticeably “off”. Usually the contaminated food which does cause food poisoning looks, smells and tastes alright.Food poisoning is not infectious, but outbreaks of the illness often affect more than one person. The reason is that the bacteria which cause food poisoning can infect the large quantity of food prepared for many people. However, it does not follow that everybody who eats the contaminated food becomes ill and nobody knows why some people seem to escape doing so.Food poisoning is so common nowadays that almost everyone has suffered from it, especially people who live in urban areas. This is so because city dwellers are used to eating mass-produced food in public areas where hygiene is often neglected. As people become familiar with the symptoms of food poisoning, few bother to visit their doctor when they have one of the milder forms of this illness, so it is very difficult to say just how widespread it is.26. The underlined words “this cause” (the second paragraph) probably means “_”.A. poisonB. rotten foodC. popular beliefD. contaminated food27. What are mainly described in paragraph 1?A. The reasons for food poisoningB. Food poisoningC. The symptoms of food poisoningD. The working of the bacteria 28. Food poisoning is very common in places where people _.A. eat out a lotB. are neglectedC. are dirtyD. love to entertain29. Which of the following is an example of mass-produced food in public areas?A. An apple bought in the supermarketB. A packet of dried beansC. Canned fruit juiceD. Fried noodles at a street stall30. People would not be _ to visit their doctor if they suffer from mild food. A. sick B. able C. want D. botheredBThe Wang family decided to go abroad for their Christmas holiday.“Where would you like to go?” Mr. Wang asked his family over dinner.“England,” Tony said eagerly.“Im sorry, England is too expensive and we cant afford to go there,” his father said.“How about Thailand?” Janet asked. “There is a special package tour on promotion at the moment and the price is quite reasonable. Ive the travel brochure here. Look.”Mr. Wang called on the travel agent, made a booking and paid a deposit for the tour. Several days later, when he paid the balance, the travel agent said to him. “You will get your air tickets at the airport as yours are the special group fare type. Please arrive at the airport two hours before departure on that day. Remember to wear this badge and show our people your passports in front of the check-in counter,” he continued.On the day of departure, the Wangs took a taxi to the airport. While they were approaching the check-in counter, a middle-aged man came up to them and said, “Are you traveling with Asia Travel Bureau? Im their representative and heres my identification,” pointing to the tag on his lapel. “Can I have your passports before I give you the tickets?”Unsuspectingly, Mr. Wang handed hi
