阅读理解

    Being able to take advantage of truly unlimited data is a smartphone user's dream, but everyone I've talked to about 5G is more excited about the usage unlocked by next - generation wireless devices. From smart home security to self - driving cars, all the Internet - connected equipment in your life will be able to talk to each other at lightning - fast speed with reduced delay.

    "5 G is one of those forerunners, along with artificial intelligence, of this coming data age," said Steve Koenig, senior director of market research for the Consumer Technology Association. "Self - driving vehicles are emblematic in this data age - they show application of data completely. With one single task, driving, you have large amounts of data coming from the vehicle itself, and a variety of sensors (传感器)are collecting a lot of information to model its environment as it moves. It's pulling in data from other vehicles about conditions down the road. There's lots of data behind that task, which is why we need the speed and lower latency ((延迟).

    AR glasses and virtual (虚拟的)reality headphones haven't yet been inside the mainstream, but tech companies are joyfully saying that such equipment will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to improve - or even replace - smartphones.

    Ericsson showed at February's Mobile World Congress in 2019 how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components, the glasses could rely on outside equipment for processing power.

    But don't get too excited. There's still a lot of work to be done in the meantime, including some necessary testing to make sure the radio plays nicely with basic systems and service construction so that 5G isn't concentrated only in big cities.

(1)、What does the first paragraph focus on?
A、Potential of 5G. B、The super speed of 5G. C、Usage of smart equipment. D、The future of smart equipment.
(2)、Which word can replace "emblematic" underlined in paragraph 2?
A、available B、productive C、representative D、popular
(3)、What is tech companies" attitude towards the replacement of smartphones?
A、Uncertain. B、Optimistic. C、Cautious. D、Disapproving.
(4)、Why does much work still need to be done according to the last paragraph?
A、To make radio play nicely. B、To construct big 5G cities. C、To do 5G trials effectively. D、To expand 5G coverage fully.

    One of the “Home Counties” to the north and west of London, Buckinghamshire is known for the rolling Chiltern Hills, its pretty villages, and the much-loved children's author Roald Dahl.

    The writer who penned Charlie and the Chocolate Factory, The Witches, Matilda and The Big Friendly Giant is the i9nspiration for the Whizzfizzing Festival – which will transform the market-town of Aylesbury into all kinds of music, colour and fun on Saturday, 1 July.

    Formerly known as The Roald Dahl Festival, this year's event will celebrate a broad range of children's films and bring to life some of its best-loved characters – from Alice in Wonderland and the Gruffala to The Big Friendly Giant and Harry Potter.

    Things to see and do

    The fun and festivals start at 11 a.m. with a colourful children's parade. More than 650 local school children and teachers, many in fancy dress, will march through the town carrying giant carnival puppets(木偶), with thousands of audiences lining the streets to watch.

    The parade will be followed with a range of child-friendly activities and workshops held in venues across the town.

    Don't be late for the Mad Hatters Tea Party in the Bucks County Museum, catch a splendid screening of a Roald Dahl movie in the Old        Court House, and watch leading children's authors, including Julian Clary, give readings in the Market Square.

    CBeebies' children's chef Katy Ashworth will once again be cooking up a storm with her inter-active

    Concoction Kitchen, located outside Hale Leys Shopping Centre. Little chefs will have lots of opportunities to get involved with preparing, cooking – and best of all, tasting – Katy's fabulous recipes.

    With hands-on arts and crafts workshops, storytelling sessions, live music, a fancy dress competition, street theatre and more, there is something for everyone.

    Wang Mengshu, an expert at the Chinese Academy of Engineering, said at a group discussion on the sidelines of the annual session of the National People's Congress that Wi-Fi should not be provided on high-speed trains, as it might disturb communication signals of trains and would also cost a lot in keeping trains in good condition. He also encouraged passengers to enjoy the views, instead of fixing their eyes on tiny screens of smart phones and laptops. However, on last Tuesday Beijing Youth Daily said it should be market demand that decides whether the Wi-Fi is offered on the trains or not.

    An increasing number of residents, especially young white-collar workers, are addicted to their smart phones rather than face-to-face interactions, thanks to the extensive Wi-Fi coverage across the country. That partly justifies Wang's opposition to the offering of Wi-Fi on high-speed trains, because they are not supposed to be dependent on high-tech devices. It is also evident that passengers on trains without free Wi-Fi will use their smart phones and other mobile devices less. However, whether the trains should provide a free Wi-Fi service fundamentally depends on customer demand.

    In other words, state-owned as it is, the China Railway Crop still has to obey relevant market rules, and provide technologically possible services to passengers if that is what they want. It cannot turn a blind eye to customers' wants "for the sake of their well-being".

    Free Wi-Fi, in fact, is already available on a lot of buses and coaches. This is a natural response to their competition with trains (especially high-speed ones), which are significantly faster and safer. The bus companies have been forced to improve their services to survive. It requires proper guidance, not a total ban on the bus, to make up for the negative effects of high-end technologies, such as people's increasing addiction to smart phones.

New archaeological discovers suggest that trade between Europe and Asia along the Silk Road probably began in some form many centuries earlier than once thought. The findings, coupled with a widening range of scientific and historical research, could add a fascinating new page to the epic of the Silk Road.

The latest and most surprising discovery is pieces of silk found in the hair of an Egyptian mummy from about 1000 BC, long before regular traffic on the Silk Road and at least one thousand years before silk was previously thought to be used in Egypt. Other research may extend human activity along this route back even further, perhaps a million years to the migration of human ancestors into eastern Asia.

The official origin of East-West commerce along the road is usually placed in the late 2nd century BC when an agent of the Chinese Emperor Wu-di returned from a dangerous secret mission across the western desert into the remote high country of Central Asia. The agent, Zhang Qian, travelled as far as Afghanistan and brought back knowledge of even more distant lands such as Persia, Syria and a place known as Lijien, perhaps Rome. Historians have called this one of the most important journeys in ancient times. His journey opened the way for what have been thought to be the first indirect contacts between the ancient world's two superpowers, China and Rome. Chinese silk, first traded to central Asian tribes for war horses and to the Parthians of old Persia in exchange for acrobats and ostrich eggs, was soon finding its way through a network of merchants to the luxury markets of Rome.

But the new discoveries show that Chinese silk was apparently present in the West long before the Han emperor started organized trade over the Silk Road. The research could change thinking about the early history of world trade and provide insights into the mystery of just how and when Europe and the Mediterranean lands first became aware of the glorious culture at the other end of Eurasia.

Choose the one that fits best according to the information given in the passage you have just read.

    The recession (衰退) of 2008-09 was remarkable in rich countries for its intensity, the following recovery for its weakness. The labour market has also broken the rules, as new research from the OECD, a think-tank of mainly rich countries, shows in its annual Employment Outlook.

    Young people always suffer in recessions. Employers stop hiring them; and they often get rid of new recruits because they are easier to dismiss. But in previous episodes, such as the recessions of the 1970s, 1980s and 1990s, older workers were also kicked off. This time is different. During the financial crisis in 2008, and since, they have done better than other age groups.

    The researchers focus on movements in "non-employment" as a share of the total population in three age groups between the final quarters of 2007 and 2012. This measure has the advantage of including not just unemployment, where people are looking for work, but also inactivity, where people are not seeking jobs. Whereas the average non-employment rate in the OECD has risen by four percentage points among young people and by one-and-a-half points among 25-to 54-year-olds, it has fallen by two points among the 55-64 age group.

    Why have older employees done so well? In some southern European countries they benefit from job protection not afforded to younger workers, but that did not really help them in past recessions. What has changed, says Stefano Scarpetta, head of the OECD's employment directorate, is that firms now bear the full costs of getting rid of older staff. In the past, early-retirement policies provided by governments (in the mistaken belief that these would help young people) made it cheaper to push grey-haired workers out of the door. These have largely stopped.

    Many will argue that older workers have done better at the expense of the young. That view is wrongheaded. First, it is a fallacy that a job gained for one person is a job lost for another; there is no fixed amount of work. And second, as the report shows, young and old people are by and large not substitutes in the workplace. They do different types of work in different types of occupation: younger people are keen on IT firms, for example, whereas older folk tend to be employed in more traditional industries. There are plenty of things that should be done to help the young jobless, but kicking older workers out of the workplace is not one of them.
