What do you use to get around town? A car? A bike? Your feet ? perhaps you should try a segway!
The Segway is perfect for short journeys. It’s an electric vehicle that consists of a platform between two wheels, with a pole that connects the platform to the handlebars. To ride it , you step up onto the platform, and control the Segway by moving your body. Lean forwards to go faster, and back-wards to slow down.
On older models, direction was controlled by a twist grip（扭转把手）on the left handlebar. This varies the speeds between the two motors, and a decrease in the speed of the left wheel would turn the Segway to the left . With newer models you simply lean to the left or right. Meanwhile, a gyroscope （陀螺仪）detects your movements and prevents the machine from falling over. The Segway has a maximum speed of 19 km per hour and a range of about 38 km. after that, you need to plug it and recharge the battery.
Segways are used for a variety of purposes. People with mobility problems can now enjoy walks in the country with their friends and family. Some golfers see them as an alternative to the golf cart . And dog owners now have an easier way to take the dog to the park. A few police forces use Segways, too. They allow officers to move quickly while maintaining contact with the public. They’re also becoming a common sight on airport . However, the most popular use is in tourism , particularly for city tours . Visit any major tourist city in summer, sit outside a cafe for a while and there’s a good chance you’ll see a group of tourists passing on Segways.

What do you do when nobody is around to take your picture? You take a selfie (拍照) .But what about selfies in space? On Twitter last year, NASA astronaut Edwin “Buzz” Aldrin, who famously became the second man to walk on the moon in July 1969, laid claim to a spaceflight first taking the first selfie in space during the Gemini XII mission in 1966.
“For me, it needs to be digital to be selfie,” argues Jennifer Levasseur, who is in charge of the Smithsonian National Air and Space Museum. According to Levasseur, the concept of a selfie is directly linked to Internet culture and human desire to interact on social platforms. “The thing that makes a selfie is sharing it,” she says.
Still, astronauts have been carrying cameras abroad space vehicles since the 1960s ,and they've taken plenty of pictures of themselves along the way. Astronauts had to pull the film magazines out and leave their cameras behind when they returned to Earth because early space missions were restricted by a conservative weight limit on the return trip.
A big change in space camera technology came after sad loss of the space shuttle Columbia who broke apart on its return to Earth in 2003. “Fearing that they would never be able to bring the film back from space and lose all that hard work celebrated the push for digital.” Levasseur says.
Today astronauts can have access to the Internet and social platforms in space and post true based selfies taken by digital cameras. Taking selfies and sharing them on social media is a way that astronauts in space can participate in the same activities people on Earth do every day. The first astronaut selfie that went viral(网红的) on the internet was one by Japanese astronaut Akihiko Hoshide in 2012.

A.It hardly makes any sense. B.It revolutionizes astronautics.
C.It contradicts public opinions. D.It needs to be further proved.
2.Why were cameras left in space on early space missions?
A.To lighten the load of the spaceship.
B.To test cameras under extreme conditions.
C.To prepare for the next stage of spaceexploration.
D.To take more pictures in space by remote control.
3.What advanced space camera technology?
A.The invention of new films
B.The fear of falling behind in the space race
C.The concern about the loss of valuable data
D.The popularity of space selfies on socia media
4.What is the best title for the text?
A.The Exploration of Space. B.The History of Selfies in Space.
C.The Change in Space Camera Technology. D.The Development in Space Technology.

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.
