I’m going through it right now. Last night one of our three family dogs was hit and killed by a car in front of my mother’s house. The dogs became, more or less, my mother’s surrogate children after her human children grew up and moved out and my father ran with a midlife crisis and left her. The one that was killed had bonded with my mother far more than the others.
She is extremely shocked. I loved the dog, but my true sadness currently results from having to watch my mother bear another tragedy after everything she has been through in her life. In the midst of all of this, I have to sincerely applaud the driver of the vehicle, which feels wrong, but it’s not.
I’ll start by stating it was not his fault. The dog ran after a deer into the road at night. In an effort not to hit the deer with his car, he changed direction, not seeing the dog, resulting in its death. He could have very easily continued on his way, but he did something that I hope I never forget.
In my eyes, he did the right thing. The driver pulled over, carefully wrapped our dog in a blanket he got from his car to preserve its dignity, and carried it up to my mother’s front door.
He was visibly shaking and very upset. He informed my mother of what happened and she broke down immediately. He comforted her the best a stranger could and waited with her while my sister rushed to her house. He left his information and offered assistance in any way he could.
Yes, he is the man who hit and killed our dog accidentally. What he really did was spare my mother, and potentially my sister, from coming across a horrible scene themselves while searching for the dog. He had so many choices that were far easier to make than what he chose. He did the right thing and for that, thank you, Stranger. You restored my faith in humanity.
1.What do we know about the dog killed by the driver?
A.It was killed by the driver on purpose.
B.It lost its life during a fight against a deer.
C.It was a particular favorite of the author’s mother.
D.It got killed by hitting the deer while running after it.
2.What does the underlined part “feels wrong, but it’s not” in Paragraph 2 probably mean？
A.The driver ought to answer for the dog’s death.
B.The author thought it sensible to praise the driver.
C.The author believed it was not the driver’s fault to kill the dog.
D.The driver should not take responsibility for the dog’s death at a11.
3.Which of the following can best describe the driver?
A.Self-condemned and considerate. B.Calm and far-sighted.
C.Reliable and generous. D.Irresponsible and unreasonable.
4.What may the author agree with?
A.Still waters have deep bottoms.
B.Those who are ready to believe are easy to cheat.
C.When the wound is healed，the pain is forgotten.
D.Taking responsibility is the best policy.

Google’s self-driving car is designed to work without a gas pedal(踏板)or steering wheel(方向盘). Now, the company has confirmed that the car doesn’t have any windscreen wipers either, because there’s no need for passengers to see where they are being driven.
The car requires no input from a driver, other than telling it the destination. There is no driving in the way we know it and all people inside the cars will be passengers who can spend their time paying no attention to the road. While the car may not need windscreen wipers, the lack of them may make passengers feel helpless if they are unable to see where they are going clearly.
Google’s two-seater “bubble” cars have buttons to begin and end the drive, but no other controls. An on-board computer uses data from sensors, including radar(雷达)and cameras, to make turns and navigate its way around pedestrians and other vehicles. Under the vision made public by Google, passengers might set their destination by typing it into a map or using commands. The new car can’t go faster than 25 miles per hour(40 km/h). It is electric and has to be recharged after 80 miles(129 km). They can only be used in areas that have been thoroughly mapped by Google.
Google has been testing its self-driving cars since 2009 and its steering wheel-less sample since early this summer. It intends on making its driverless cars available to consumers in the next five years. The ultimate goal of the project is computer-controlled cars that can get rid of human error, which results in about 90 percent of the 1.2 million road deaths that occur worldwide each year and it was also inspiring to start with a blank sheet of paper.
1.Why may people feel helpless riding in Google’s self-driving car?
A. They have no idea of the destination. B. There are no other controls.
C. They are unable to see the road clearly. D. The car is traveling too fast.
2.What’s the main idea of the third paragraph?
A. The tests the car needs to pass.
B. What the drivers need to drive the car.
C. The development of the new car.
D. How Google’s self-driving car works.
3.How long can Google’s self-driving car travel before being recharged?
A. 25 miles. B. 40 miles. C. 80 miles. D. 129 miles.
4.What can we learn from the last paragraph?
A. Google began to test self-driving cars this summer.
B. The majority of the road deaths are caused by drivers.
C. Driver less cars will be available to consumers next year.
D. Google’s computer controlled cars fire the drivers’ inspiration.

Last week, two companies, Kitty Hawk and Uber, announced their plans to bring flying cars to reality very soon.
Kitty Hawk president, Sebastian Thrun, announced Kitty Hawk’s flying car plans last Monday. According to its website, the car is electric-powered and will be able to travel at speeds up to 40 kilometers an hour. It says such a machine “does not require registration or a pilot’s license and may be flown in uncrowded areas for recreational purposes.” As of now, the car can only be flown over fresh water.
Kitty Hawk is making a list of people interested in buying the flying car. They must pay a deposit of $ 100. Those who get their names on the list early will receive $2,000 off the final cost of the car. However, Kitty Hawk has not yet announced the price. Its first flying cars are expected to go on sale by the end of this year.
Unlike the Kitty Hawk company, Uber does not plan to build its flying cars. Uber expects to launch flying taxis in Dallas-Ft. Worth, Texas, US by 2020. Like the Kitty Hawk car, Uber flying taxis will use electric power. Uber says its flying taxis could travel up to 241 kilometers an hour. The company says that could reduce the travel time between San Francisco and San Jose, California from 2 hours on the road to 15 minutes in the air.
Riders could use the Uber app to book a flying taxi to take them to their destinations. The company has not yet said how costly air taxi travel would be compared to road taxi travel.
Sooner than you think, flying cars may appear in the sky. Much convenience as they will bring, just imagine having to avoid other flying cars. Also, what if your battery dies when you are in the air? And, how will you know where to land?
1.What may Kitty Hawk’s flying car be used for at present?
A. Accelerating the speed. B. Having fun.
C. Advertising the company. D. Fetching water.
2.What do we know about Kitty Hawk’s flying car from the third paragraph?
A. It costs two thousand dollars each. B. It can travel over water.
C. It offers $100 to its potential buyers. D. It hasn’t gone to market.
3.In what way is Uber’s flying taxi similar to Kitty Hawk’s flying car?
A. They travel at the same speed. B. They are electric-powered.
C. They are supported by the Uber app. D. They require a flying license.
4.What is the purpose of the last paragraph of the text?
A. To call for public donations. B. To introduce some advantages.
C. To promote interest in science. D. To talk about possible problems.

When you don’t have a car and need to get around, are you more likely to call for an Uber or Lyft, or a cab? Last Friday, Lyft — the ride-sharing company, went public as its stocks (股票) started trading on the market. Lyft has become the first big initial public offering of the “gig economy” age. While the company is not making profits yet, it is changing the meaning of work. What is gig economy and what makes it so appealing?
Gig works are independent contracts (合同) or part-time jobs such as Uber. In the gig economy, companies hire independent contractors instead of full-time employees. This is different from traditional companies where full-time workers hold a lifetime career. In the past, only small companies hired contractors, while today, employers like Amazon and Google rely on temporary workforce. These companies save costs as they are not legally required to provide healthcare benefits, retirement savings or paid time off to gig workers.
Gig work appeals to different people for different reasons. For some, it affords flexible timings and for otliers who are looking for full-time jobs, it provides a source of income to support themselves. Some people work a full-time job and supplement (补充) their salary with gig jobs such as driving for Uber or Lyft.
Joining the gig economy may be simple, but maintaining a steady career is easier said than done. Gig work comes with unsteady pay and workloads. You're your own boss. It sounds fun, but when you have no self-control and an unsteady job, you might splurge all your money the first week and live on bread pieces for the rest of the month! Besides a strong sense of responsibility, gig workers have to stay up to date to get companies to hire them.
Despite the challenges gig workers face, nearly 60 million Americans are part of this workforce. As this number grows, we have to see how society and companies adapt to this new world of work!
1.What can be learnt about Lyft from the passage?
A.It has built up a large fortune.
B.It marks the arrival of gig economy age.
C.It employs a fixed number of full-time workers.
D.It appeals to people as a means of public transport.
2.Who are most likely to become gig workers?
A.People seeking for a steady income.
B.Those desperate to get paid vacations.
C.People in need of flexible working hours.
D.Those concerned about retirement accounts.
3.What does the underlined word “splurge” in paragraph 4 mean?
A.Spend money freely. B.Deposit money automatically.
C.Earn money quickly. D.Allocate money randomly.
4.What is the message mainly conveyed in the passage?
A.Gig workers have to face some potential challenges.
B.Gig workers have to possess some much-needed qualities.
C.The appearance of gig companies will solve the job problems.
D.People should adjust to new work trends with the rise of gig companies.
