When will the first bus leave?A. 11:30 amB. 12:30 pmC. 13:20 pmD. 14:40 pmBGerman carmaker Audi equipped some of its 2017 models in the United States with a new technology. The technology is known as V-to-I. Drivers will see a countdown on the car’s instrument panel (仪表板) to show when the traffic signal will turn green or red. The equipment was included on Audi’s Q7, A4 and A4 “Allroad” models built after June 1, 2016.The service began in 2016 in at least five “smart”American cities. The information comes from government agencies that collect data to predict traffic flow. A private company partners with government officials to send the data to cars.The countdown message goes away a few seconds before the light changes for safety. Pom Malhotra is the general manager of Audi’s connected cars division. He said the system was designed to provide drivers with a sense of ease and convenience. “A better informed driver means a less stressed driver,” an announcer said in an Audi video explaining the technology.The company said the idea was to let drivers know exactly the time left before a signal changes. It suggested they use the time to make sure other passengers are fine or monitor car operations.The technology raises the possibility that some drivers may use the vehicle’s countdown to talk on the telephone or send text messages. But Audi said it would never tell drivers to text while driving -- an activity that is illegal in almost all 50 states.The goal was to integrate traffic infrastructure (基础设施) with cars on many city roads. This would let traffic signals use the vehicle data to regulate traffic, suggest better driving paths, or suggest speeds needed to hit all green lights.4.What function does the new technology add to the car?A.Reminding drivers to monitor car operations.B.Preventing drivers phoning when driving.C.Providing information on traffic signals.D.Reporting traffic flow to government officials.5.Why does the countdown message disappear before the light changes?A.To avoid misleading drivers.B. To help drivers hit green lights.C. To provide the newest information.D. To make sure drivers focus on driving.6. How does the new system benefit drivers?A. Making driving safe.B. Making driving fun.C. Making drivers relaxed when driving.D. Making drivers have more spare time.7. Which of the following can replace the underlined word “integrate” in the last paragraph?A. Combine.B. Compare.C. Equip.D. Replace.C“Shake a leg” and “show a leg” are usually discussed together, but it isn’t at all clear how they are connected. Both phrases have more than one meaning.“Shake a leg”means “hurry up”according to the definition in the New York Magazine in 1904. Before that, “shake a leg” had another meaning, which was “to dance”. There are several quotations from all kinds of American and British sources from the mid-19th century that are related to dancing. For example, the Dubuque Democratic Herald, October 1863, in an advertisement for a local ball: “Nearly every man in town able to shake a leg has purchased a ticket.”“Show a leg” means either “make an appearance”, or it means “hurry up”. The second meaning isn’t commonly used, nor is it old. Whatever the source, it isn’t the original meaning of “show a leg”. Most commentators report that the phrase derives from the Royal Navy and that this was the order given to sailors to put a foot from their hammocks (吊床) and get up.The use of “show a leg” as a wake-up call is well documented. John Masefield (Poet Laureate from 1930 to 1967) was a trainee mariner on HMS Conway until 1891. He reported the full version of the morning call as: “Heave out, heave out, heave out, heave out! Away! Come all you sleepers, Hey! Show a leg.” That’s the earliest quotation of the naval call I can find, although it may have been used well before 1891.An alternative version comes from the fact that women were allowed on board Royal Navy ships in the 19th century and that they were allowed to stay asleep after the sailors had been woken. In the morning the bosun’s mates (水手长助手) had to check whoever was still asleep and did so by requiring them to show a leg over the side of the hammock. If a leg was hairy, it was probably male and its owner was ordered to get up and begin work. Believe that if you will; personally, I don’t.All in all, although both of the two English slangs are sometimes used to mean “hurry up”, they are two independent phrases that were coined with different meanings.8. How many ways does the slang “show a leg” come from?A. 1.B. 2.C. 3.D. 4.9. In which sentence does “shake a leg” have a different meaning?A. I will shake a leg with him at the next ball with great pleasure.B. Nearly every man in town able to shake a leg has purchased a ticket.C. They wanted to shake a leg on a TV show.D. You must shake a leg to catch the last bus.10. What is the author’s attitude to the version mentioned in Paragraph 5?A. Doubtful.B. Supportive.C. Indifferent.D. Neutral.11. What is the author’s purpose of writing the text?A. To persuade readers to learn slangs seriously.B. To describe “shake a leg” and “show a leg”.C. To distinguish “shake a leg” and “show a leg”.D. To remark on “shake a leg” and “show a leg”.DAbout a month after I joined Facebook, I got a call from Lori Goler, a highly regarded senior director of marketing at eBay. She made it clear that this was a business call. “I want to apply to work with you at Facebook,” she said. “Instead of recommending myself, I want to ask you: What is your biggest problem, and how can I solve it?”My jaw hit the floor. I had hired thousands of people over the previous decade and no one had ever said anything remotely like that. People usually focus on finding the right role for themselves, with the implication that their skills will help the company. Lori put Facebook’s needs front and center. It was a killer approach. I responded, “Recruiting is my biggest problem. And, yes, you can solve it.”Lori never dreamed she would work in recruiting, but she jumped in. She even agreed to trade earnings for acquiring new skills in a new field. Lori did a great job running recruiting and within months was promoted to her current job, leading People@Facebook.The most common metaphor for careers is a ladder, but this concept no longer applies to most workers. As of 2010, the average American had eleven jobs from the ages of eighteen to forty-six alone. Lori often quotes Pattie Sellers, who came up with a much better metaphor: “Careers are a jungle gym, not a ladder.”As Lori describes it, there’s only one way to get to the top of a ladder, but there are many ways to get to the top of a jungle gym. The jungle gym model benefits everyone, but especially women who might be starting careers, switching careers, getting blocked by external barriers, or reentering the workforce after taking time off. The ability to create a unique path with occasional dips, detours (弯路), and even dead ends presents great views of many people, not just those at the top. On a ladder, most climbers are stuck staring at the butt of the person above.12.Why did Lori make the call?A.She helped Facebook to solve the biggest problem.B.She wanted to make a business deal with Facebook.C.She tried to ask for a pay rise in Facebook.D.She wanted to become an employee in Facebook.13.What impressed “me” most?A.Lori was good at running recruiting.B.Lori attached great importance to Facebook’s needs.C.Lori jumped in Facebook with no adequate experience.D.Lori was skilled in marketing at eBay.14.What can we infer from the last two paragraphs?A.Now all people don’t tend to climb the ladder.B.None on the ladder can enjoy the great views.C.Jungle gyms offer limited exploration for employees.D.A pregnant woman, jobless, benefits little from the jungle gyms.15.What is the best title of the passage?A.How to get promoted at work.B. Facebook’s Biggest Problem.C. Applying for a Job in Facebook.D. It’s a Jungle Gym, not a Ladder.第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。

召见肥义同他议论天下大事，谈了五天才结束。

武灵王到北边巡视中山国的地界，到了房子县，又去代地，北到无穷，西到黄河，登上黄华山顶。

然后召见楼缓商议说：“我们先王趁着世事的变化，做了南边领地的君长，连接了漳水、滏水的险阻，修筑长城，又夺取了蔺城、郭狼，在荏地打败了林胡人，可是功业尚未完成。

如今中山国在我们腹心，北面是燕国，东面是东胡，西面是林胡、楼烦、秦国、韩国的边界，然而没有强大兵力的救援，这样下去国家要灭亡，怎么办呢？要取得高出世人的功名，必定要受到背离习俗的牵累。

我要穿起胡人服装。

”楼缓说：“很好。

”可是群臣都不愿意。

当时肥义在旁侍奉，武灵王说：“简子、襄子二位主君的功业，就在于考虑到了胡、翟之利。

做臣子的，受宠时应有明孝悌、知长幼、顺从明理的德操，通达时应建立既可利民又能益君的功业，这两方面是臣子的本分。

如今我想继承襄主的事业，开拓胡人、翟人所住之地，可是找遍世间也见不到这样的贤臣。

为了削弱敌人，用力少而能取得更多的功效，可以不耗尽百姓的力气，就能继续两位先主的勋业。

凡是有高出世上功业的人，就要承受背弃习俗的牵累；有独特智谋的人，就要听任傲慢民众的埋怨。

如今我要穿胡人服装骑马射箭，并用这个教练百姓，可是世人一定要议论我，怎么办呢？”肥义说：“我听说做事犹疑就不会成功，行动犹豫就不会成名。

您既然考虑决定承受背弃风俗的责难，那末就无需顾虑天下的议论了。

追求最高道德的人不附和世俗，成就大功的人不找凡夫俗子商议。

AWalk For CharityDear friends,Please join us for our annual Walk For Charity. Starting in Weldown, you and your friends can choose a delightful 10, 20 or 30 kilometers’ route.The money raised will provide support to help people all over the world. Start collecting your sponsors now and then simply come along on the day. Please read the instructions below carefully, especially if you require transport to and from Weldown.See you on Sunday 15 April.V Jessop: Walk coordinatorPS. Well done to last year’s walkers for helpingto raise a grand total of ￡21,000. The moneyhas already been used to build a children’s playground.START TIME:10 km: 8-10 am 20 km: 8-10:30 am 30 km:8-11:30 amThe organizers reserve the right to refuse late-comers.CLOTHING should be suitable for the weather. If rain is forecast, bring some protection and be prepared for all possibilities. It is better to wear shoes that have been worn in, rather than ones that are new.ROUTE MAPS will be available from the registration point. The route will be sign-posted and arranged. Where the route runs along the road, walkers should keep to one side in single file, facing oncoming traffic at all times. If you need help along the route, please inform one of the staff.Free car parking is available in car parks and on streets in Weldown.BUSES:For the 10 and 20 kilometers’routes, a bus will be waiting at Fenton to take walkers back to Weldown. The bus will leave every half hour starting at midday. The service is free and there is no needto book.1.When may a walker be forbidden to join in the walk?A.Parking a car on the streets.B. Being late for the walk.C. Choosing the shortest route.D. Bringing no clothes for the weather.2. What are the walkers advised to do?A. To prepare new shoes for the walk.B. To book the bus ahead of time.C. To care about their own safety.D. To donate at the registration point.3. When will the first bus leave?A. 11:30 amB. 12:30 pmC. 13:20 pmD. 14:40 pmBGerman carmaker Audi equipped some of its 2017 models in the United States with a new technology. The technology is known as V-to-I. Drivers will see a countdown on the car’s instrument panel (仪表板) to show when the traffic signal will turn green or red. The equipment was included on Audi’s Q7, A4 and A4 “Allroad” models built after June 1, 2016.The service began in 2016 in at least five “smart”American cities. The information comes from government agencies that collect data to predict traffic flow. A private company partners with government officials to send the data to cars.The countdown message goes away a few seconds before the light changes for safety. Pom Malhotra is the general manager of Audi’s connected cars division. He said the system was designed to provide drivers with a sense of ease and convenience. “A better informed driver means a less stressed driver,” an announcer said in an Audi video explaining the technology.The company said the idea was to let drivers know exactly the time left before a signal changes. It suggested they use the time to make sure other passengers are fine or monitor car operations.The technology raises the possibility that some drivers may use the vehicle’s countdown to talk on the telephone or send text messages. But Audi said it would never tell drivers to text while driving -- an activity that is illegal in almost all 50 states.The goal was to integrate traffic infrastructure (基础设施) with cars on many city roads. This would let traffic signals use the vehicle data to regulate traffic, suggest better driving paths, or suggest speeds needed to hit all green lights.4.What function does the new technology add to the car?A.Reminding drivers to monitor car operations.B.Preventing drivers phoning when driving.C.Providing information on traffic signals.D.Reporting traffic flow to government officials.5.Why does the countdown message disappear before the light changes?A.To avoid misleading drivers.B. To help drivers hit green lights.C. To provide the newest information.D. To make sure drivers focus on driving.6. How does the new system benefit drivers?A. Making driving safe.B. Making driving fun.C. Making drivers relaxed when driving.D. Making drivers have more spare time.7. Which of the following can replace the underlined word “integrate” in the last paragraph?A. Combine.B. Compare.C. Equip.D. Replace.C“Shake a leg” and “show a leg” are usually discussed together, but it isn’t at all clear how they are connected. Both phrases have more than one meaning.“Shake a leg”means “hurry up”according to the definition in the New York Magazine in 1904. Before that, “shake a leg” had another meaning, which was “to dance”. There are several quotations fromall kinds of American and British sources from the mid-19th century that are related to dancing. For example, the Dubuque Democratic Herald, October 1863, in an advertisement for a local ball: “Nearly every man in town able to shake a leg has purchased a ticket.”“Show a leg” means either “make an appearance”, or it means “hurry up”. The second meaning isn’t commonly used, nor is it old. Whatever the source, it isn’t the original meaning of “show a leg”. Most commentators report that the phrase derives from the Royal Navy and that this was the order given to sailors to put a foot from their hammocks (吊床) and get up.The use of “show a leg” as a wake-up call is well documented. John Masefield (Poet Laureate from 1930 to 1967) was a trainee mariner on HMS Conway until 1891. He reported the full version of the morning call as: “Heave out, heave out, heave out, heave out! Away! Come all you sleepers, Hey! Show a leg.” That’s the earliest quotation of the naval call I can find, although it may have been used well before 1891.An alternative version comes from the fact that women were allowed on board Royal Navy ships in the 19th century and that they were allowed to stay asleep after the sailors had been woken. In the morning the bosun’s mates (水手长助手) had to check whoever was still asleep and did so by requiring them to show a leg over the side of the hammock. If a leg was hairy, it was probably male and its owner was ordered to get up and begin work. Believe that if you will; personally, I don’t.All in all, although both of the two English slangs are sometimes used to mean “hurry up”, they are two independent phrases that were coined with different meanings.8. How many ways does the slang “show a leg” come from?A. 1.B. 2.C. 3.D. 4.9. In which sentence does “shake a leg” have a different meaning?A. I will shake a leg with him at the next ball with great pleasure.B. Nearly every man in town able to shake a leg has purchased a ticket.C. They wanted to shake a leg on a TV show.D. You must shake a leg to catch the last bus.10. What is the author’s attitude to the version mentioned in Paragraph 5?A. Doubtful.B. Supportive.C. Indifferent.D. Neutral.11. What is the author’s purpose of writing the text?A. To persuade readers to learn slangs seriously.B. To describe “shake a leg” and “show a leg”.C. To distinguish “shake a leg” and “show a leg”.D. To remark on “shake a leg” and “show a leg”.DAbout a month after I joined Facebook, I got a call from Lori Goler, a highly regarded senior director of marketing at eBay. She made it clear that this was a business call. “I want to apply to work with you at Facebook,”she said. “Instead of recommending myself, I want to ask you: What is your biggest problem, and how can I solve it?”My jaw hit the floor. I had hired thousands of people over the previous decade and no one had ever said anything remotely like that. People usually focus on finding the right role for themselves, with the implication that their skills will help the company. Lori put Facebook’s needs front and center. It was a killer approach. I responded, “Recruiting is my biggest problem. And, yes, you can solve it.”Lori never dreamed she would work in recruiting, but she jumped in. She even agreed to trade earnings for acquiring new skills in a new field. Lori did a great job running recruiting and within months was promoted to her current job, leading People@Facebook.The most common metaphor for careers is a ladder, but this concept no longer applies to mostworkers. As of 2010, the average American had eleven jobs from the ages of eighteen to forty-six alone. Lori often quotes Pattie Sellers, who came up with a much better metaphor: “Careers are a jungle gym, not a ladder.”As Lori describes it, there’s only one way to get to the top of a ladder, but there are many ways to get to the top of a jungle gym. The jungle gym model benefits everyone, but especially women who might be starting careers, switching careers, getting blocked by external barriers, or reentering the workforce after taking time off. The ability to create a unique path with occasional dips, detours (弯路), and even dead ends presents great views of many people, not just those at the top. On a ladder, most climbers are stuck staring at the butt of the person above.12.Why did Lori make the call?A.She helped Facebook to solve the biggest problem.B.She wanted to make a business deal with Facebook.C.She tried to ask for a pay rise in Facebook.D.She wanted to become an employee in Facebook.13.What impressed “me” most?A.Lori was good at running recruiting.B.Lori attached great importance to Facebook’s needs.C.Lori jumped in Facebook with no adequate experience.D.Lori was skilled in marketing at eBay.14.What can we infer from the last two paragraphs?A.Now all people don’t tend to climb the ladder.B.None on the ladder can enjoy the great views.C.Jungle gyms offer limited exploration for employees.D.A pregnant woman, jobless, benefits little from the jungle gyms.15.What is the best title of the passage?A.How to get promoted at work.B. Facebook’s Biggest Problem.C. Applying for a Job in Facebook.D. It’s a Jungle Gym, not a Ladder.第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。

The technology is known as V-to-I. Drivers will see a countdown on the car’s instrument panel (仪表板) to show when the traffic signal will turn green or red. The equipment was included on Audi’s Q7, A4 and A4 “Allroad” models built after June 1, 2016.The service began in 2016 in at least five “smart”American cities. The information comes from government agencies that collect data to predict traffic flow. A private company partners with government officials to send the data to cars.The countdown message goes away a few seconds before the light changes for safety. Pom Malhotra is the general manager of Audi’s connected cars division. He said the system was designed to provide drivers with a sense of ease and convenience. “A better informed driver means a less stressed driver,” an announcer said in an Audi video explaining the technology.The company said the idea was to let drivers know exactly the time left before a signal changes. It suggested they use the time to make sure other passengers are fine or monitor car operations.The technology raises the possibility that some drivers may use the vehicle’s countdown to talk on the telephone or send text messages. But Audi said it would never tell drivers to text while driving -- an activity that is illegal in almost all 50 states.The goal was to integrate traffic infrastructure (基础设施) with cars on many city roads. This would let traffic signals use the vehicle data to regulate traffic, suggest better driving paths, or suggest speeds needed to hit all green lights.4.What function does the new technology add to the car?A.Reminding drivers to monitor car operations.B.Preventing drivers phoning when driving.C.Providing information on traffic signals.D.Reporting traffic flow to government officials.5.Why does the countdown message disappear before the light changes?A.To avoid misleading drivers.B. To help drivers hit green lights.C. To provide the newest information.D. To make sure drivers focus on driving.6. How does the new system benefit drivers?A. Making driving safe.B. Making driving fun.C. Making drivers relaxed when driving.D. Making drivers have more spare time.7. Which of the following can replace the underlined word “integrate” in the last paragraph?A. Combine.B. Compare.C. Equip.D. Replace.C“Shake a leg” and “show a leg” are usually discussed together, but it isn’t at all clear how they are connected. Both phrases have more than one meaning.“Shake a leg” means “hurry up” according to the definition in the New York Magazine in 1904. Before that, “shake a leg” had another meaning, which was “to dance”. There are several quotations from all kinds of American and British sources from the mid-19th century that are related to dancing. For example, the Dubuque Democratic Herald, October 1863, in an advertisement for a local ball: “Nearly every man in town able to shake a leg has purchased a ticket.”“Show a leg” means either “make an appearance”, or it means “hurry up”. The second meaning isn’t commonly used, nor is it old. Whatever the source, it isn’t the original meaning of “show a leg”. Most commentators report that the phrase derives from the Royal Navy and that this was the order given to sailors to put a foot from their hammocks (吊床) and get up.The use of “show a leg” as a wake-up call is well documented. John Masefield (Poet Laureate from 1930 to 1967) was a trainee mariner on HMS Conway until 1891. He reported the full version of the morning call as: “Heave out, heave out, heave out, heave out! Away! Come all you sleepers, Hey! Show a leg.” That’s the earliest quotation of the naval call I can find, although it may have been used well before 1891.An alternative version comes from the fact that women were allowed on board Royal Navy ships in the 19th century and that they were allowed to stay asleep after the sailors had been woken. In the morning the bosun’s mates (水手长助手) had to check whoever was still asleep and did so by requiring them to show a leg over the side of the hammock. If a leg was hairy, it was probably male and its owner was ordered to get up and begin work. Believe that if you will; personally, I don’t.All in all, although both of the two English slangs are sometimes used to mean “hurry up”, they are two independent phrases that were coined with different meanings.8. How many ways does the slang “show a leg” come from?A. 1.B. 2.C. 3.D. 4.9. In which sentence does “shake a leg” have a different meaning?A. I will shake a leg with him at the next ball with great pleasure.B. Nearly every man in town able to shake a leg has purchased a ticket.C. They wanted to shake a leg on a TV show.D. You must shake a leg to catch the last bus.10. What is the author’s attitude to the version mentioned in Paragraph 5?A. Doubtful.B. Supportive.C. Indifferent.D. Neutral.11. What is the author’s purpose of writing the text?A. To persuade readers to learn slangs seriously.B. To describe “shake a leg” and “show a leg”.C. To distinguish “shake a leg” and “show a leg”.D. To remark on “shake a leg” and “show a leg”.DAbout a month after I joined Facebook, I got a call from Lori Goler, a highly regarded senior director of marketing at eBay. She made it clear that this was a business call. “I want to apply to work with you at Facebook,” she said. “Instead of recommending myself, I want to ask you: What is your biggest problem, and how can I solve it?”My jaw hit the floor. I had hired thousands of people over the previous decade and no one had ever said anything remotely like that. People usually focus on finding the right role for themselves, with the implication that their skills will help the company. Lori put Facebook’s needs front and center. It was a killer approach. I responded, “Recruiting is my biggest problem. And, yes, you can solve it.”Lori never dreamed she would work in recruiting, but she jumped in. She even agreed to trade earnings for acquiring new skills in a new field. Lori did a great job running recruiting and within months was promoted to her current job, leading People@Facebook.The most common metaphor for careers is a ladder, but this concept no longer applies to most workers. As of 2010, the average American had eleven jobs from the ages of eighteen to forty-six alone. Lori often quotes Pattie Sellers, who came up with a much better metaphor: “Careers are a jungle gym, not a ladder.”As Lori describes it, there’s only one way to get to the top of a ladder, but there are many ways to get to the top of a jungle gym. The jungle gym model benefits everyone, but especially women who might be starting careers, switching careers, getting blocked by external barriers, or reentering the workforce after taking time off. The ability to create a unique path with occasional dips, detours (弯路), and even dead ends presents great views of many people, not just those at the top. On a ladder, most climbers are stuck staring at the butt of the person above.12.Why did Lori make the call?A.She helped Facebook to solve the biggest problem.B.She wanted to make a business deal with Facebook.C.She tried to ask for a pay rise in Facebook.D.She wanted to become an employee in Facebook.13.What impressed “me” most?A.Lori was good at running recruiting.B.Lori attached great importance to Facebook’s needs.C.Lori jumped in Facebook with no adequate experience.D.Lori was skilled in marketing at eBay.14.What can we infer from the last two paragraphs?A.Now all people don’t tend to climb the ladder.B.None on the ladder can enjoy the great views.C.Jungle gyms offer limited exploration for employees.D.A pregnant woman, jobless, benefits little from the jungle gyms.15.What is the best title of the passage?A.How to get promoted at work.B. Facebook’s Biggest Problem.C. Applying for a Job in Facebook.D. It’s a Jungle Gym, not a Ladder.第二节（共5小题；每小题2分，满分10分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。
