The Titanic was the biggest ship in the world when it sailed on its ill-fate

27、d maiden voyage in 1912. Of the 2,227 passengers and crew aboard, more than 1,500 died. The ship, which was headed to New York City, carried the rich and famous on its first voyage. It also carried immigrants, who were seeking a better life in America.Relatives of people who sailed on the Titanic, h

28、istorians, authors and people fascinated by the story of the unsinkable ship, are on the Balmoral. They want to remember the doomed ship and those who died on her first and last voyage. The historic liner had set sail on April 10, 1912, from Southampton. Late at night on April 14, she hit an iceberg

29、. In the early morning hours of April 15, the Titanic sank.The Balmoral is following Titanics original route from Southampton. First, the modern-day cruise liner docked in the port of Cherbourg, France, where the Titanic had picked up more passengers. On Monday afternoon, the Balmoral stops in Cobh,

30、 Ireland, the Titanics last port of call before sailing to New York. Balmoral will then cruise the North Atlantic Ocean to the location where Titanic hit an iceberg that ripped the ships hull(外壳). On Sunday, April 15, at 2:20 a.m.the time the Titanic went downpassengers and crew will hold a memorial

31、 service. The next two days will be spent in Halifax, Canada, where many victims of the sinking are buried. Then, the Balmoral will reach its final destination in New York City, where Titanic was supposed to dockbut never did.Until today, several teams of divers have explored the site. They have rec

32、overed some items such as dishes and silverware and put them on public display. And more trips are planned to the wreckage in the future. The Titanic and its passengers and crew have been remembered in books, movies and TV programs. But theres a much more important contribution that Titanic gave us.

33、 After she sank, lawmakers and shipbuilders made ships safer. It took a terrible tragedy to make ship travel safer for all.51. How many passengers in Titanic survived at last? A. More than 1500. B. About 1309.C. About 1000.D. Less than 750.52. How many countries does the Balmoral reach before sailin

34、g to New York? A. Two. B. Three. C. Four. D. five. 53. The Balmoral will stay in Canada just _. A. in memory of the dead passengers in the Balmoral B. in memory of the survivors in TitanicC. in memory of the dead passengers in TitanicD. in memory of the survivors in the Balmoral 54. What might be th

35、e most important contribution of sunken Titanic? A. Its site attracts more exploring teams. B. It makes the later ships more secure.C. Some of its items are on public display. D. More trips are planned to its wreckage.BWork Your MindHeres something to think about the next time you ask your teacher f

36、or help: struggling with schoolwork on your own can help you learn. According to a recent study, the more you struggle while you are learning new information, the better you can remember it later.This theory might surprise you. When teachers are presenting new information, they often give students l

37、ots of help. But a new study shows this may not be the best way to support learning. “Dont be too quick to get help when learning something new,” education expert Manu Kapur told TFK. “Try to work on it yourself even if it means trying different ways.”Kapur came up with the idea that struggling can

38、lead to better learning. Then he tested it out on students in Singapore. He separated students into two groups. In the first group, students were asked to solve math problems with the teachers help. In the second group, students were asked to solve the same problems by helping one another, instead o

39、f getting help from the teacher. With the teachers help, students in the first group were able to find the correct answers. Students in the second group did not solve the problems correctly. But they did come up with a lot of good ideas. The students were then tested on what they had learned. The gr

40、oup without any help from a teacher scored much higher than the group who had help. Kapur said working to find the answers helped students understand the process, not just the solution.Kapurs advice for kids is to put a lot of effort into learning something new rather than going to your teacher for

41、help. “Simply doing a little work or nothing at all wont work,” says Kapur. “The struggle needs to be a genuine attempt to figure out or solve a problem in as many ways as possible.”55. When you have doubt on schoolwork, youd better _. A. ask your teacher for help B. make it clear by yourself C. ask

42、 your classmates to help you D. ask your parents for help 56. Whats Manu Kapur educational idea on learning new knowledge? A. Give students much help as soon as possible. B. Let students learn it on themselves in one way. C. Let students learn it by themselves in the same way. D. Let students learn

43、it for themselves in different ways.57. How did Kapur check his idea on better learning? A. By asking questions. B. By solving art problems. C. By group comparations.D. By solving science problems. 58. What is most important in learning knowledge?A. Getting the teachers help. B. Getting the students

44、 help. C. Grasping the learning course. D. Receiving the final solution. CA recent Living Social survey showed that Americans may live up to their poor reputation while travelling abroad. But whats more surprising is that many of those surveyed self-identified themselves as ugly Americans and the wo

45、rlds worst travelers.Those in the U.S. ranked themselves as the worst travellers by a shocking 20 per cent, followed by 15 per cent saying the Chinese were the most substandard tourists.Americans topped the list as being the worst-behaved travelers in a survey of 5,600 respondents, 4,000 of whom wer

46、e Americans. Other respondents were in Australia, Canada, Ireland and the United Kingdom. But even American respondents considered their compatriots(同胞) as the worst travelers from a list of 16 nationalities.Canadians and Australians also put Americans in the No. 1 spot. Irish respondents pointed to

47、 U.K. residents and U.K. respondents gave Germans the nod. On the other hand, 37% of Americans opted for none of the above in answer to the worst-tourists question, displaying more tolerance and open-mindedness than the other nationalities.Other survey questions had respondents admitting pilfering f

48、rom hotels. Four in ten U.S. survey-takers said theyd stolen something mostly towels (28%) and bathrobes (8%). Other popular pinched items included pillows, remote controls, Bibles and sheets.Not surprising is that Americans have less time off from work than other nationalities. Americans reported g

49、etting 16 days off, compared with 28 days for the Irish, 27 days for Australians, 23 days for U.K. workers; and 21 days for Canadians.In the travel mishaps department, the most common travel disaster reported by Americans was lost luggage on an airline (21%); bad weather (21%); and getting very lost

50、 (16%).As for places Americans most want to see, Disney World and Las Vegas made the top 10, but they werent at the top of the heap. And New York didnt make the cut.59. What percentage of American respondents is in the survey?A.20 % B.15% C.71% D.37%60. The underlined word “pilfering” in Para. 5 mos

51、t probably means _. A. takingB. bringingC. stealing D. borrowing.61. According to the survey, what kind of things are most taken away by Americans?A. towels and pillowsB. bathrobes and remote controls.C. towels and BiblesD. bathrobes and towels.62. Whats the best title of this passage? A. Chinese we

52、re announced as the worlds worst travellers.B. The global worst travellers were announced. C. Disney World is the best destination to Americans. D. European travellers were the best in the worldDBaby girls make their way directly for dolls as soon as they can crawl, while boys will head for cars, a

53、study has shown. The findings, the first to show differences in very young babies, suggest there is a biological basis to their preferences.Psychologists Dr Brenda Todd from City University London carried out an experiment involving 90 babies aged 9 months to 36 months. The babies were allowed to ch

54、oose from seven toys. Some were typically boys toys - a car, a digger, a ball and a blue teddy. The rest were girls toys: a pink teddy, a doll and a cooking set. They were placed a meter away from the toys;and could pick whichever toy they liked their choice and the amount of time they spent playing

55、 with each toy were recorded.Of the youngest children (9 to 14 months), girls spent significantly longer playing with the doll than boys, and boys spent much more time with the car and ball than the girls did. Among the two and three-year-olds, girls spent 50 percent of the time playing with the dol

56、l while only two boys briefly touched it. The boys spent almost 90 percent of their time playing with cars, which the girls barely touched. There was no link between the parents view on which toys were more appropriate for boys or girls, and the childrens choice.Dr Brenda Todd said, “Children of thi

57、s age are already exposed to much socialization. Boys may be given toys that go while girls get toys they can care for, which may help shape their preference. But these findings agree with the former idea that children show natural interests in particular kinds of toys. There could be a biological b

58、asis for their choices. Males through evolution have been adapted to prefer: moving objects, probably through hunting instincts(本能), while girls prefer warmer colors such as pink, the colour of a newborn baby.” 63. Baby boys and girls have different toy preferences probably because _. A. baby boys a

59、re much more activeB. baby girls like bright colours more C. their parents treat them differentlyD. there is a natural difference between them 64. Both baby boys and baby girls like to play with _ according to the study.A. a ball B. a teddy C. a car D. a doll65. What can we infer from Paragraph 3?A.

60、 Nine-month-old baby boys dont play with dolls at all.B. Two-year-old baby girls sometimes play with cars and balls.C. The older the babies are, the more obvious their preference is.D. Parents should teach their babies to share each others toys.66. What conclusion did Dr. Brenda Todd draw from the r

61、esults of the study?A. Adults purposely influence their babies preference.B. Babies preference isnt affected by social surroundings.C. Baby boys preferring to moving toys will be good at hunting.D. Baby girls preferring warmer colors will be warm-hearted. EA new argument has been put forward as to w

62、hether penguins are disturbed by the presence of tourists in Antarctica. Previous research by scientists from Keil University in Germany monitored Adelie penguins and noted that the birds heart rates increased dramatically at the sight of a human as far as 30 meters away. But new research using an a

63、rtificial egg, which is equipped to measure heart rates, disputes this. Scientists from the Scott Polar Research Institute at Cambridge say that a slow moving human who does not approach the nest too closely, is not viewed as a threat by penguins. The earlier findings have been used to partly explai

64、n the 20 per cent drop in populations of certain types of penguins near tourist sites. However, tour operators have continued to insist that their activities do not adversely affect wildlife in Antarctica, saying they encourage non-disruptive behavior in tourists, and that the decline in penguin num

65、bers is caused by other factors.Amanda Nimon of the Scott Polar Research Institute spent three southern hemisphere summers at Cuverville Island in Antarctica studying penguin behavior towards humans. “A nesting penguin will react very differently to a person rapidly and closely approaching the nest,

66、” says Nimon. “First they exhibit large and prolonged heart rate changes and then they often flee the nest leaving it open for predators (掠夺者) to fly in and remove eggs or chicks.” The artificial egg, specially for the project, monitored both the parent who had been disturbed when the egg was placed

67、 in the nest and the other parent as they both took it in turns to guard the nest.However, Boris Culik, who monitored the Adelie penguins, believes that Nimons findings do not invalidate his own research. He points out that species behave differently - and Nimons work was with Gentoo penguins. Nimon

68、 and her colleagues believe that Culiks research was methodologically flawed because the monitoring of penguins responses needed capturing and restraining the birds and fitting them with beart-rate transmitters. Therefore, argues Nimon, it would not be surprising if they became stressed on seeing a

69、human subsequently. 67. According to the passage, what overall message is presented?A. No firm conclusions are drawn.B. Neither Culiks nor Nimons findings are of much value.C. Penguin reduction is closed related to tourist behavior.D. Tourists are not responsible for the fall in penguin numbers.68.

70、Which ONE argument of the following is stated in the passage?A. Penguins are harder to research when they have young.B. Tour operators should encourage tourists to avoid Antarctica.C. Not all penguins behave in the same way.D. Penguins need better protection from tourists.69. What do you notice abou

71、t the views presented in the passage?A. They are groundless.B. They are factual.C. They are descriptive.D. They are conflicting.70. What does the underlined word (final line) probably mean?A. Later on.B. Calmly.C. Separately.D. In the same place.第四部分:书面表达第一节:完成句子(共10小题;每小题2分,满分20分)阅读下列各小题,根据所给的汉语句子,
