Castles(城堡)and temples wear away after hundreds of years, but the symbols and E-books came from the development of words on the stone often survive.1. science and technology, and can be read online. Many people believe that regular books will be one day replaced by e-books.
Books and e-books share lots of similarities. They are both items created by great minds,2. You can draw lines or highlight some details on books or e-books as notes. The notes can be kept for a long time.
3.Firstly, books don’t have to be charged, while e-books need electricity if we want to read them. Meanwhile, spending too much time reading e-books may do harm to our eyes. Moreover, e-books don't share the same weight when held in the hand as regular books, nor do they give that sense of fulfillment that comes from finishing a thick book. However，e-book devices(设备)are easy to carry.4.
A disadvantage of e-book devices is that people tend to get distracted(分心)when they’re using one, as many devices often have apps or games on them.5.
Whichever you prefer, both books and e-books are just a way to help us gain knowledge and get to know other people 's experiences. They are both necessary, so it's too early to say one will disappear.
A. But they have diferences as well
B They take less space than books
C Indeed our lives are formed by what books we read
D. This is similar to how the words in books manage to live on
E. They all have an index to introduce the main topic of each book
F But with a regular book, your mind is always absorbed in the words
G Each individual can decide which reading method is best for them based on their own needs
Getting stuck in a traffic jam is one of the most boring problems for people living in big cities.The fact that you’re moving so slowly leads too stress,anger and the wish that your car could just fly over the traffic like an airplane.
Soon,however, that wish could come true .On May 8, US car-renting company Uber showed off what it described as “the transportation mode of the future: on-demand air transport,”reported ABC News .
According to Nikhill Goel, head of products for Uber Air, the company's air taxi service may launch test flights in the US cities of Dallas and Los Angeles , as well as Dubai in the United Arab Emirates, as early as 2020. If everything goes according to plan, passengers will be able to fly to work by 2023 .
When the Olympics comes to Los Angeles in 2028 . Uber “expects to have hundreds , if not thousands , of its aircraft in the skies.” Goel told Newsweek .
So what would Uber's flying vehicles be like ?
They are small , electric aircraft that take off and land vertically (垂直地) , and they give off zero emissions (排放) and are quiet enough to operate in cities .
Just like an airplane , the vehicles will have fixed wings to help them glide . But while a helicopter has just one big fixed rotor (定量) . Uber's vehicles will have multiple rotors , which will help increase fuel efficiency (效率) while reducing emissions and noise.
Because of these fixed wines and multiple rotors . Uber’s flying taxis“should be quieter and safer than a helicopter.” reported ABC News .
However , the service still has a long way to go before it's ready to accept passengers.For example , to avoid any potential accidents . Uber is working with NASA to study air traffic control problems associated with low-flying aircraft. But just as Dubai's Mayor Betty Price said in a news release . “This program is revolutionary and future -oriented (面向未来的). ”

In Western society, especially in the English-speaking world, the chance for young people to see the other countries and experience life is considered important. Many young people, when they finish school at the age of 18, take a gap year before they go to university.
Parents often want their children to grow up a little and see what the real world is like when they finish school. Although they are worried about their safety, many think that the advantages of independence and experience are worth the worries. Children are encouraged to be brave, independent and to explore the world on their own or with friends.
Young people also want to experience freedom and see what life is like on the other side. This other side could be the other side of the world or just the other side of life. For example, if they have a rich life, they may want to see how people in poor areas live.
A gap year after school is also an important chance for young people to spend time thinking about what they want to do with their lives. A little bit of growing up and experience will help them make their important career decisions, especially when they are unsure about what they want to study.
Another reason for going straight after school is to get a break from studying before they start the next few years of university. So anywhere you travel in the world, you will meet young European people exploring the world.
So much of the world has been travelled and explored. The young people are now looking for more worthy experiences. Some of them work as volunteers to do something for the country they are visiting. Many gap year volunteers are now spending a few months teaching English in Thailand, helping feed giant pandas in China or building a well(井) in a village in Africa.
These young people’s wish to explore the world is an expression of the values of the societies that they are part of. Both discovering the world and making a positive difference in it are important parts of the Western mind.
