AI was ten when my father first sent me flowers. I had been taking ballet lessons for four months, and the school was giving its yearly performance. As a member of the beginners’chorus group, I was surprised to hear my name called out at the end of the show along with the leading dancers and to find my arms full of red roses. I can still feel myself standing on that stage, seeing my father’s big smiles.Those roses were the first of many bunches accompanying all the milestones in my life. Getting all those roses was wonderful, but they brought a sense of embarrassment. I enjoyed them, but I also felt they were too much for my small achievements.Not for my father. He did everything in a big way. Once, when mother told him I needed a new party dress, he brought home a dozen. His behavior often left us without money for other more important things. Sometimes I would be angry with him.Then came my 16th birthday. It was not a happy occasion. I was fat and had no boyfriend. And my well-meaning father furthered my suffering by giving me a party. As I entered the dining room, there on the table next to my cake was a huge bunch of flowers, bigger than any before.I wanted to hide. Now everyone would think my father had sent flowers because I had no boyfriend to do it. Sweet 16, and I felt like crying. But my best friend, Jenny, whispered, “Boy, you’re lucky to have a father like that.”As the years passed, other occasions—birthdays, awards, graduations—were marked with Dad’s flowers. Those flowers symbolized his pride, and my success. As my fortunes grew, my father’s health became worse, but his gifts of flowers continued until he died. I covered his coffin with the largest, reddest roses I could find.Often during the dozen years since, I felt an urge to buy a big bunch to fill the living room, but I never did. I knew it would not be the same.Then one birthday, the doorbell rang. I was feeling blue because I was alone. My husband and my two daughters were away. My 10-year-old son, Tommy, had run out earlier with a “see you later”. So I was surprised to see Tommy at the door.“Forgot my key,”he said. “Forgot your birthday too.”He pulled a bunch of roses from behind his back.“Oh, Tommy,”I cried. “I love flowers!”1. The writer felt embarrassed getting her first roses because .A. she wasn’t a member of leading dancersB. she thought her success wasn’t big enoughC. she regarded the flowers as a milestone in her lifeD. she found herself standing on the center of the stage2. Which of the following statements is true according to the passage?A. The father made the writer happy by giving her a party.B. The father was proud of the writer in her growth stages.C. The father didn’t leave the family money for important things.D. The father bought the writer flowers when she got angry with him.3. Tommy came back again, mainly to .A. take back his keysB. show his love for flowersC. encourage his motherD. bring his mother birthday gift4. Which of the following would be the best title for the passage?A. Love in BloomB. Father and MeC. Pleasure and EmbarrassmentD. Father’s FlowersBChoosing where to live may be one of the biggest decisions you’ll make when you move to Sydney, but you’ll have plenty of help.Temporary arrival accommodationBefore you move to Sydney，we recommend that you book a temporary place to stay.

According to the passage, the most popular choice among students is .A. living off campusB. living in host familiesC. living in self-catered flats on campusD. living in fully catered houses on campusCA few weeks ago, I called an Uber to take me to the Boston airport for a flight home for the holidays. As I slid into the back seat of the car, the warm intonations(语调) of the driver’s accent washed over me in a familiar way.I learned that he was a recent West African immigrant with a few young children, working hard to provide for his family. I could relate: I am the daughter of two Ethiopian immigrants who made their share of sacrifices to ensure my success. I told him I was on a college break and headed home to visit my parents. That’s how he found out I went to Harvard. An approving eye glinted at me in the rearview window, and quickly, we crossed the boundaries of rider and driver. I became his daughter, all grown up—the product of his sacrifice.And then came the fateful question: “What do you study?”I answered “history and literature”and the pride in his voice faded, as I knew it might. I didn’t even get to add “and African-American studies”before he cut in, his voice thick with disappointment, “All that work to get into Harvard, and you study history?”Here I was, his daughter, wasting the biggest opportunity of her life. He went on to deliver the age-old lecture that all immigrant kids know. We are to become doctors (or lawyers, if our parents are being generous)—to make money and send money back home. The unspoken demand, made across generations, which my Uber driver laid out plainly, is simple: Fulfill your role in the narrative(故事) of upward mobility so your children can do the same.I used to feel anxious and backed into a corner by the questioning, but now asa junior in college, I’m grateful for their support more than anything. This holiday season, I’ve promised myself I won’t get annoyed at their inquiries. I won’t defensively respond with “but I plan to go to law school!”when I get unrequested advice. I’ll just smile and nod, and enjoy the warmth of the occasion.8. Why did the author feel warm at the driver’s accent?A. The driver took her to the Boston airport.B. The author became the driver’s daughter.C. The driver worked hard to provide for his family.D. The author’s parents were also African immigrants.9. What disappointed the driver？A. The author’s attitude towards him.B. The school that the author is attending.C. The author’s major in history and literature.D. The author’s interests in African-American studies.10. Why are immigrant kids expected to be doctors or lawyers?A. Their parents want them to move upward in society.B. Their parents are high-achieving as well.C. They have much more knowledge.D. They are very smart in general.11. How did the author react to the driver’s questioning？A. Getting upset.B. Feeling satisfied.C. Defending herself.D. Appreciating his concern.DTime talks. It speaks more plainly than words. Time communicates in many ways.Consider the different parts of the day, for example. The time of the day when something is done can give a special meaning to the event. It is not customary to telephone someone every early in the morning. If you telephone him early in the day, the time of the call shows that the matter is very important and requires immediate attention. If someone receives a call during sleeping hours, he assumes it is a matter of life or death. The time chosen for the call communicates itsimportance.In social life, time plays a very important part. In the United States, guests tend to feel they are not highly regarded if the invitation to a dinner party is extended only three or four days before the party date. But this is not true in all countries. In other areas of the world, it may be considered foolish to make an appointment too far in advance because plans which are made for a date more than a week away tend to be forgotten.The meaning of time differs in different parts of the world. Thus, misunderstandings often arise between people from cultures that treat time differently. Promptness(准时) is valued highly in American life, for example. If people are not prompt, they may be regarded as impolite or not fully responsible. In the U.S., no one would think of keeping a business partner waiting for an hour; it would be too impolite. A person who is five minutes late is expected to make a short apology.This way of treating time is quite different from that of several other cultures. This helps to explain the unfortunate experience of a certain agriculturist from the United States, assigned to duty in another country. After a long delay, the agriculturist was finally agreed an appointment with the Minister of Agriculture. Arriving a little before the appointed hour, the agriculturist waited. The hour came and passed. At this point he suggested to the secretary that perhaps the minister did not know he was waiting in the outer office. This gave him the feeling of having done something to solve the problem, but he had not. Twenty minutes passed, then thirty, then forty-five. To an American, that is the beginning of the “insult period”. No matter what is said in apology, there is little that can remove the damage done by an hour’s wait in an outer office. Yet in the country where this story took place, a forty-five-minute waiting period was not unusual.In the West, particularly in the United States, people tend to think of time as something fixed in nature. As a rule, Americans think of time as a road stretching into the future, along which one progresses. The road has many sections, which are to be kept separate—“one thing at a time”. People who cannot plan events are not highly regarded. Thus, an American may feel angry when he has made an appointment with someone and then finds a lot of other things happening at the same time.Since time has such different meanings in different cultures, communication is often difficult. We will understand each other a little better if we can keep this fact in mind.12. According to the passage, an announcement broadcast during class must be very important because ________．A. it is a customary time to makeB. it makes everyone surprisedC. it requires immediate attentionD. it speaks more plainly than words13. The author mentions an agriculturist’s experience in order to show ________．A. the value of promptness for AmericansB. the cultural differences in treating timeC. the bad manners of the Minister of AgricultureD. the importance of time in different parts of the day14. The underlined word “insult”in Paragraph5 probably means ________．A. boringB. patientC. shamefulD. hopeless15. We can learn from the passage that people will understand better if ________．A. they are concerned with the value of timeB. they know how to communicate with each otherC. they escape dealing with many things at one appointed timeD. they keep in mind that different cultures treat time differently第二节（共５小题；每小题２分，共10分）根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项, 并在答题卡上将该项涂黑。

Ⅰ.阅读理解Some weightloss camps，which are rare in China just a few years ago，have multiplied in Beijing，Qingdao，Shenzhen，and other cities.Today about 15 percent of adults, or 200 million Chinese, are reportedly overweight.Of these，90 million—about 7 percent—are obese(极肥胖的)．Experts say the obesity epidemic(流行病) is spreading to children，though more slowly than in adults.The obesity，they say，will do harm to the health of China’s citizens and economy.“We’re seeing a very large number of teenagers who are quit e heavy and aren’t moving much，”said Barry Popkin，a nutrition(营养) professor.Popkin carries out an ongoing health-and-nutrition survey of 16，000 households in China.He says more kids today are overeating and putting on weight “quite quickly.”In just ten ye ars China’s childhood obesity rate has doubled，with the greatest gains coming in urban areas.“In big cities it’s a big problem.”Some experts blame the extra fat on a range of factors，many of them tied to China’s rapidly changing economy and culture.The diets of Chinese adults and children are far higher in meats，fish，eggs，dairy products，fats and sugars than ever before.In addition，kids—especially city dwellers—are more sedentary today and spend more time indoors in front of homework，television，computer games，and the Internet.Shuwen Ng，a health economist，says that kids in China now have pocket money，and they spend a portion of it on junk food.Ng adds that advertising and peer groups influence kids’food choices.Certain foods，such as new candies or fast food，have attractive features.China’s childhood obesity rate still fall behind that of the United States，where some 15 percent of kids are said to be obese.But the longterm effects are equally serious.【解题导语】本文说的是中国人在发胖，并重点说明了中国儿童的发胖情况，强调了发胖的危害。

He worked as a waiter in a restaurant and his problem was acid reflux(胃酸倒流), a disease that influences as many as 40 percent of Americans, a marked increase in recent years. Reflux can lead to esophageal (食道的) cancer, which has increased by about 500 percent since the 1970s. The drugs we use to treat reflux don't always work and may even increase the risk of developing cancer when used long term.What is responsible for these worrying developments? For one, our poor diet, with its huge increases in the intake of sugar, fat, soft drinks, and unhealthy foods. But another important fact has been overlooked:_dinnertime. Over the past twenty years, the time of my patients' evening meals has become later and later. Dinner－already pushed back by longer work hours－is often further, delayed (推迟) by activities such as shopping and exercise.In my experience, the single most important treatment for reflux is to avoid late eating. A patient with reflux came to see me because her father and uncle died ofesophageal cancer, and she was afraid of getting it too. Her nightly routine (常规) included a 9 p．m. dinner with at least two bottles of red wine. The reflux was serious, and changes were needed.She listened, then did not come back to see me for a year. “For the first two months, I just hated you，”she told me, “and for the next two months, I was having some trouble eati ng. I guessed I was going to die of esophageal cancer.” Then she added, “You know, we're the reason that it's not so easy to get 6 p. m. reservation (预约) at the good restaurants anymore.”To stop the increase in reflux disease, we have to stop eating at least three hours before bed.
