25、项。 A When I was about six years old, my mother came home one day and found that I had collected half dozen babies of the neighborhoodall of them too young to walkand had them sitting before me on the floor while I was teaching them to wave their arms. When she asked the explanation of this, I inform
26、ed her that it was my school of dance. She was amused, and placing herself at the piano, she began to play for me. This school continued and became very popular. Later on, little girls of the neighborhood came and their parents paid me a small sum to teach them. This was the beginning of what afterw
27、ards proved a very well-paid occupation. My mother took me to a famous ballet teacher, but his lessons did not please me. When the teacher told me to stand on my toes, I asked him why, and when he replied “Because it is beautiful,” I said that it was ugly and against nature and after the third lesso
28、n, I left his class, never to return. This stiff（僵硬的）and commonplace gymnastics which he called dancing only disturbed my dream. I dreamed of a different dance. I did not know just what it would be but I was feeling out towards an invisible world into which I guess I might enter if I found the key.
29、My art was already in me when I was a little girl, and it was owing to the heroic and adventurous spirit of my mother that it was not stifled（窒息）. I believe that whatever the child is going to do in life should be begun when it is very young. I wonder how many parents realize that by the so-called e
30、ducation they are giving their children, they are only driving them into the commonplace, and refuse them of any chance of doing anything beautiful or original. 51. The attitude of the authors mother toward her school of dance was _. A. negative B. neutral C. supporting D. indifferent 52. The author
31、 thought that ballet was _. A. elegant, graceful and gentle B. stiff, ugly and unnatural C. charming, attractive and cool D. touch, inviting and challenging 53. From this passage we know that the author owed her success in art to _. A. her strict and adventurous ballet teacher B. the good training t
32、hat her parents gave her C. the support and understanding of her mother D. the inspiration gained from the neighborhood babies 54. The key message we may get from the passage is that _. A. parents should help to develop the natural gift of their kids B. parents should give a hand to their kids doing
33、 something original C. a good mother should be both heroic and adventurous in education D. ballet is no good as a form of dance and thus should be forbidden B When a consumer finds that something he or she bought is faulty（假冒的）or in some other way does not live up to what the producer says for it, t
34、he first step is to present the warranty（保单），or any other records that might help, at the store of buying. In most cases, this action produces results. However, if it does not, there are various means the consumer may use to gain satisfaction. A simple and common method used by many consumers is to
35、complain directly to the store manager. In general, the “higher up” the consumer takes him or her complaint, the faster he or she can expect it to be settled. In such a case, it is usually settled in the consumers favor, taking it as true that he or she has a just right. Consumer should complain in
36、person whenever possible, but if they can not get to the place of buying, it is acceptable to phone or write the complaint in a letter. Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can show clearly what is wrong with what was bought in q
37、uestion. If this can not be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example, “the left speaker does not work at all and the sound coming out of the right one is unclear” is better than “This stereo（立体音
38、响） does not work.” The store manager may advise the consumer to write to the producer, if so, the consumer should do this, stating the complaint as politely and firmly as possible. But if a polite complaint does not achieve the expected result, the consumer can go a step further. He or she can threa
39、ten to take the seller to court or report the seller to a public organization responsible for protecting consumers rights. 55. To gain a relatively quick settlement of his problem, which one below is a consumer advised to complain to _. A. the manager B. the producer C. a shop assistant D. a public
40、organization 56. The most effective complaint about what was bought can be made by _. A. asking politely to change it B. saying firmly it is of the poor quality C. writing to the producer directlyD. explaining exactly what is wrong with it 57. The passage mainly informs us _. A. how to make the effe
41、ctive complaint B. how to settle a consumers complaint C. how to avoid buying something wrong D. how to deal with complaints from consumer 58. According to the passage, the last way a consumer has to use is _. A. to find the manager and reason with him B. to write to the producer stating the problem
42、s C. to gather several fighters to threaten the seller D. to warn the seller of reporting to a public organization C Not long after I started teaching at Kamiakin Junior High near Seattle, Michael, my six-month-old son, was diagnosed with elodysplastic syndrome（骨髓发育不良综合症）. Its a pre-leukemia（白血病前期）d
43、isease. He needs a bone-marrow transplant（骨髓移植）. Soon after the diagnosis, everyone in the family had a blood test in the hope that one of us would be the bone-marrow donor（捐献者）. On March 20, my wife Kristi called me at work to share some good news, Amy is a perfect match! As a result of the donor s
44、earch, however, a dark cloud cast a shadow over our hope. The bone-marrow transplant would cost more than $200,000. We would gladly pay that to save any one of our children-but how could we pay it? The next day, Steven Mezich, Kamiakins principal had a talk with me. Jeff, he said, with your permissi
45、on I want to propose a fund-raiser（募捐）at this afternoons staff meeting, to help your family. I was surprised. Stevens thoughtful offer raised my spirits, though I doubted it could do much to help us overcome such a huge and urgent financial problem. That afternoon, Dameon Sharkey, a student from my
46、class, walked into my office with his mom and gave me his life savings of $60 - all in $5 bills. And the next day after the staff meeting, we received wishes for Michaels recovery, prayers, loving support, $350 cash, and checks. The outpouring of love from these friends moved me to tears. But thats
47、not the end. Joe Kennedy, Kamiakins humanities teacher, challenged the schools students to see what they could do to help Michael. These high-spirited junior-high kids immediately went to work, making plans to start a walkathon, hold a raffle（抽奖）, set up donation boxes, and attract news coverage. As
48、 a result of the students efforts, stories appeared in The Journal American and NEW YORK TIMES. Scores of independent, unrelated efforts took place all over Seattle area. A month after Dameons gift opened the floodgates, Michaels fund totaled $220,000. Our baby would get a second chance! 59. What wo
49、rried the author most was whether there was _. A. a bone-marrow donorB. enough time for Michael to wait C. support from the societyD. money to cover the cost of treatment 60.

51、B. Michael was cured in the end C. the students made a great contributionD. a bone-marrow transplant costs a lot D National Estuaries Day is an annual celebration of the coastal areas where rivers meet the seaestuaries. Celebrated on the last Saturday in September, National Estuaries Day is a great
52、opportunity to learn more about these magical ecosystems. It is also the occasion to inform people from coast to coast about their connection to these beautiful places and how they can encourage its healthy future. National Estuaries Day was first established 21 years ago as part of Coast Weeks. Cou
53、ntless National Estuaries Day activities range from photography contests, canoe trips, estuary clean-ups, exhibits, to guided estuary tours. However, most people are simply unaware of how much they depend on estuaries and how much their actions can have an effect on other places that might not seem
54、to be so close to home. Your home, school or office is thousands of miles away from the nearest coast, but what each of us does affects an estuary and even peoples health. As ecosystems, estuaries are under threat from human activities such as pollution and over fishing. Industrial, agricultural, an
55、d domestic（家庭的）waste enter rivers and are poured into estuaries. Contaminants can be introduced which do not break up rapidly in the marine environment. Water flows seaward through systems of rivers, lakes and wetlands. Much of the air we breathe and water we drink, in turn, come to us on atmospheri
56、c（大气的）currents from oxygen produced by ocean plants and moisture（湿气）rising from the sea. By celebrating National Estuaries Day you can help others understand that no matter where we live we are connected and we all share one world ocean, with our fate tied to the future health of our estuaries and o

Estuarieswhere rivers meet the sea E Changes in the value of currency help some parts of the economy and hurt others. When people go to foreign cou
61、ntries, they have direct experience with the exchange rate（汇率）of money. International travelers must use their own money to buy the currency of the country they are visiting. For example, Americans on holiday in a foreign country can buy more currency when the dollar has a high exchange value. So a
62、high exchange value is good for vacationers. It is not so good for exporting. A strong dollar means that American exports are more costly. Other countries are less likely to import products from the United States because they are too costly. American agricultural goods, computers and airplanes all a
63、re more costly on the world market when the dollar is strong. However, sellers of foreign goods within the United States are helped by a strong dollar. A strong dollar means that American companies can buy more with the same amount of money. They can sell goods at a low price in the United States an
64、d still make a profit. This helps to increase the American trade deficit（贸易逆差）. A weak dollar helps American companies that do business overseas. For example, the American computer industry gains because its products are less costly to foreign buyers. Financial magazines report that technology compa
65、nies like Intel and Microsoft have increased profits because of the weak dollar. Increased trade helps reduce the American trade deficit. The United States Department keeps information on Americas imports and exports. Information on the third quarter of 2022 shows that Americas trade deficit did fal

Only in this way, can the health of youngsters be greatly improved. 听力录音稿 Text 1 M: Would you like to be a driver？ W: No, I m not interested in driving. I
