I thought that I should go back to Montreal , Quebec, my hometown for a visit. My main goal was to relax in preparation for the challenges of my retirement in the coming year.Through my stay in Montreal, I met lots of Chinese who are struggling to succeed and then lead a better life in Canada.Some travelled thousands of miles to get knowledge. When I spoke with some of them about the major barrier they had to face after they arrived in Canada, they all talked about the two official languages of Canada. But I was impressed by their ability to express their ideas while switching between English and French.Almost all of those people said they often felt homesick. They miss their families and friends. Though Montreal ha lots of Chinese restaurants, they long for a home-cooked meal.I met some tourists who were trying to realize their childhood dreams of experiencing the life in a developed country. When I asked them if Montreal had lived up to their expectations, they hesitated. They said that reality never agrees with fantasies. However, they were glad to have the opportunity to visit Montreal and didn’t regret taking the trip.Not all the Chinese people I met were happy. I once met a young lady who met with a gentleman through the Internet. However, to her disappointment, he disappeared after he promised to marry he promised to marry her in Montreal.I was served by another Chinese person who could not handle the challenges of studying in an English environment and ended up working in a restaurant with minimum pay.Exploring different parts of the world, without any doubt, is an enriching experience. However, one should be realistic when it comes to leaving his hometown to set up a new life in a foreign country. One should take the time to examine the advantages and the shortcomings of the venture before they decide to chase an uncertain dream od achieving success or leading a better life.56.The writer want to her hometown to ___A. meet her old friendsB. study a new languageC. go on with her teachingD. prepare for her retirement life57.The main barrier for some Chinese to get knowledge in Canada is___A. foodB. homesicknessC. languageD. income58.The writer thinks that___A. overseas Chinese are good at communication in Canada.B. the trip to Montreal is a good chance for people to study.C. overseas Chinese feel disappointed at their life in Canada.D. people should think carefully before chasing the dreams abroad.59.What is the best title for the passage?A.

A research report .B. Website.C. A personal blog.D. A journal.COld FossilScientists have found what they think is probably the oldest fossil on Earth, a remnant of life from 3.7 billion years ago when Earth's skies were orange and its oceans green.In an newly melted part of Greenland, Australian scientists found the leftover structure from a community of microbes （微生物）that lived on an ancient seafloor. Based on their analysis of the fossils, the researchers determined that they are 220 million years older than those discovered in Western Australia, which were 3.48 billion years old.The discovery shows life may have formed quicker and more easily than once thought, about half a billion years after Earth formed. And that may also give hope for life forming elsewhere, such as Mars, said study co-author Martin VanKranendonk of the University of New South Wales and director of the Australian Center for Astrobiology. "It gives us an idea how our planet evolved and how life gained a foothold," VanKranendonk said.Scientists had thought it would take at least half a billion years for life to form after the molten Earth started to cool a bit, but this shows it could have happened quicker, he said. That's because the newly found fossil is far too complex to have developed soon after the planet's first life forms, he said.In an outcrop of rocks that used to be covered with ice and snow which melted after an exceptionally warm spring, the Australian team found stromatolites（叠层石）, which are layered structures that are often produced by a community of microbes. The stromatolites were about 1 to 4 centimeters high."It is like the house left behind made by the microbes, " Vankranendonk said. "Scientists used the layers of ash from volcanos and tiny zircon（锆石）with uranium and estimated that they date back to 3.7 billion years ago."The dating seems about right, said Abigail Allwood, a NASA astrobiologist who found the previous oldest fossil, from 3.48 billion years ago, in Australia. But Allwood said she is not completely convinced that what Vankranendonk's team found once was alive. She said the evidence wasn't conclusive enough that it was life and not a geologic quirk（地质巧合）. "It would be nice to have more evidence, but in these rocks that's a lot to ask," Allwood said in the email.63. The underlined words " gained a foothold" in Paragraph 3 mean ______________.A. continued.B. changedC. increasedD. started64. We can learn from Paragraph 4 _______________.A. the fossil appeared soon after the birth of the earthB. the fossil formed soon after the earth's first lifeC. life formed earlier than the newly found fossilD. life appeared about half a billion years ago65. What is Abigail Allwood's attitude towards the newly found fossil?A. Neutral.B. Skeptical.C. Objective.D. Supportive66. According to the passage, ________________.A. the previous fossils are a geologic quirkB. the previous fossils are made up of stromatolitesC. the newly found fossils come from western AustraliaD. the newly found fossils have a history of 3.7 billion yearsDWhen taking an Uber—Should you tip or notTaking an Uber car may no longer be a direct driver-passenger and guilt-free experience. The ride-sharing experience is about to get awkward.With the wide application of the Internet, Uber , a new approach to your destination instead of taking an ordinary taxi , has become more popular recently .However, benefits won’t come without its fair share of drawbacks.Uber drivers are a part of the so-called sharing economy: They use their own vehicles, receive customer reviews via the app’s five-star rating system and make their own hours. unlike other services, Uber claimed that drivers all over the country could clearly alert customers that tipping is not included. Those drivers that expect to be tipped can make their wishes known. But the company is holding to its official no-tip-required line, according to its website. “once you arrive at your destination, your fare is automatically charged to your credit card on file—There’s no need to tip.” Although drivers value their independence——the freedom to push a button rather than punch a clock , lack of a clear policy ,however , leaves Uber drivers in a vulnerable(脆弱的) position : If they ask a customer for a tip or put up a sign , that customer could give a driver a low star-rating , and the driver could finally be deactivated from the app.But has the company done a good job working with customers? Some observers say that this new grey area for tipping will create awkwardness about whether they should tip or not ----something most Uber customers have not had to deal with until now. Uber did not re spond to customers’ comment, just leaving their rating in the air.Providing an option to tip on an app sends a clear message to customers to reach into their pockets. Nearly 30% people would be more likely to leave a tip if they were presented with a “no tip” button, according to Guinn’s 2015 survey of roughly 500 people. When people are presented with three tip choices -----20%, 25% or 30% ----they’re more likely to choose the middle option even if it’s more than the traditional 20%, according to a separa te 2014 analysis of 13 million New York City taxi rides.If the service is twice as expensive during a rain storm or public transport delay, the customer has the right not to tip. However, if the driver is extra helpful or avoids traffic to reach your destination in a more timely manner, you could give an extra tip, says Uber , who will leave tipping options in the hands of the consumer rather than the app .67. Compared with taxi drivers, Uber drivers ______.A. enjoy more freedom and choicesB. support the company’s practiceC. clock up the miles while drivingD. receive customers reviews directly68. The underlined word “deactivated’ in paragraph 4 probably means ____.A. removedB. degradedC. trackedD. charged69. From the survey we can conclude most customers________.A. would probably tip if there is an optionB. usually do as the “no tip” sign suggestsC. tip because of Uber drivers’ good serviceD. are disappointed to reach into their pockets70. What causes the awkwardness between Uber drivers and their customers ?A. Customers take advantage of the new grey area for tipping .B. There is no specific policy from the Uber to follow.C. It’s up to customers to decide the drivers’ earningsD. customers tend to pay least among the 3 choices.第二节（共5小题；每小题2分，共10分）Giant Panda Is No Longer EndangeredA leading international group has taken the giant panda off its endangered list thanks to decades of conservation efforts, but China’s government is unwilling to accept the change, saying it did not view the status of the country’s beloved symbol as any less serious.The International Union for Conservation of “endangered” species, reflecting its growing numbers in the wild in southern China. 71 That is the result of work by Chinese agencies to carry out hunting bans and expand forest reserves.In a statement, China’s State Forestry Administration said that it doubted the classification change because pandas’ natural habitats have been mainly separated by human causes. The animals live in small, isolated groups of as few as 10pandas that struggle to reproduce and face the risk of disappearing altogether. If we relax our conservation work, the populations and habitats of giant pandas would still suffer a great loss. 72 Therefore, we’re not being alarmist (危言耸听的) by continuing to emphasize the panda species’ endangered status.73 John Howard, a senior official at World Society for the Protection of Animals, expressed his satisfaction over the effective measures taken by the Chinese government. The Chinese government and the World Wild Fund (WWF) first established the Wolong National Nature Reserve in Sichuan province in 1980. Wild panda numbers have since slowly rebounded as China cracked down on the skin trade. 74Over the last few decades, international groups and the Chinese government have worked to save wild pandas and breed them in face of their extinction. It is not surprising that the WWF, whose logo has been a panda since 1961, celebrated the panda’s re-classification. 75A.As a result, our achievements would be quickly lost.B.The wild panda population jump to 1,864 in 2014 from 1,596 in 2004.C.Still, other animal protection organizations praised the recovery of the pandas.D.Panda has long been a symbol of China and the global conservation movement.E.And China gradually expanded its protected forest areas to cover 1.4 million hectares now.F.Some pandas have been sent to zoos around the world as a gesture of Chinese diplomatic goodwill.G.It says that aggressive investment does pay off when science, political will and engagement come together.第四部分：书面表达（共两节，35分）第一节（15分）假设你是红星中学学生会主席李华。
