All networks like 3G and 4G will be things of the past, because 5G will be reachable in the near future. So, what’s so special about a 5G future? First of all, its download speed can be as fast as 20GB/s, which is 100 to 200 times that of 4G. But what’s more impressive is 5G’s low delay rate. Now, 4G takes an average of 200 milliseconds(毫秒) to send and receive information. But 5G will get it down to 1 millisecond.
5G is a great breakthrough. It’s going to change the way equipment connects to the Internet, and more importantly, to each other. And self-driving cars may be one of the biggest breakthroughs to come out of 5G. Human reaction time is 200 milliseconds, yet we still have accidents every day. The self-driving car under a 5G network could react and communicate its reaction to hundreds of cars around it, all within 1 millisecond. It’ll play a great role in preventing car accidents and ending traffic jams completely.
5G can benefit us in many other ways.Operations could be performed by robots controlled by experts from the other side of the world. Therefore, more lives will be saved in time. Factories can be staffed by robots that can communicate their tasks to each other, and they can do more work efficiently over a 5G network. Imagine a group of drones(无人机) flying over a field of crops, using sensors(传感器) on the ground to sort, pick, feed, and water plants all on their own. Then farmers won’t have to work so hard anymore.
However, 5G is not perfect. One major disadvantage has to do with why it’s so fast. 5G uses the millimeter waves, while 4G uses the 15 to 40 centimeter-long waves. And shorter waves go fast but not very far.On 4G networks, the signal can go 10 kilometers. But the 5G signal can go at most 300 meters, and it can’t even go through walls or rain. So, what does that mean? Having such a short signal distance means we need to build a lot of transmitters(信号发射塔) in the future.

The past ages of man have all been carefully labeled by anthropologists. Descriptions like ‘Palaeolithic Man’, ‘Neolithic Man’, etc., neatly sum up whole periods. When the time comes for anthropologists to turn their attention to the twentieth century, they will surely choose the label ‘Legless Man’. Histories of the time will go something like this: ‘in the twentieth century, people forgot how to use their legs. Men and women moved about in cars, buses and trains from a very early age. There were lifts and escalators in all large buildings to prevent people from walking. This situation was forced upon earth dwellers of that time because of miles each day. But the surprising thing is that they didn’t use their legs even when they went on holiday. They built cable railways, ski-lifts and roads to the top of every huge mountain. All the beauty spots on earth were ruined by the presence of large car parks.’
The future history books might also record that we were deprived of the use of our eyes. In our hurry to get from one place to another, we failed to see anything on the way. Air travel gives you a bird’s-eye view of the world—or even less if the wing of the aircraft happens to get in your way. When you travel by car or train a blurred (=not clear) image of the countryside constantly smears the windows. Car drivers, in particular, are forever obsessed with the urge to go on and on: they never want to stop. Is it the lure (引诱;诱惑) of the great motorways, or what? And as for sea travel, it hardly deserves mention. It is perfectly summed up in the words of the old song: ‘I joined the navy to see the world, and what did I see? I saw the sea.’ The typical twentieth-century traveler is the man who always says ‘I’ve been there. ’You mention the remotest, most evocative (引起记忆的) place-names in the world like El Dorado, Kabul, Irkutsk and someone is bound to say ‘I’ve been there’—meaning, ‘I drove through it at 100 miles an hour on the way to somewhere else.’
When you travel at high speeds, the present means nothing: you live mainly in the future because you spend most of your time looking forward to arriving at some other place. But actual arrival, when it is achieved, is meaningless. You want to move on again. By traveling like this, you suspend all experience; the present ceases to be a reality: you might just as well be dead. The traveler on foot, on the other hand, lives constantly in the present. For him traveling and arriving are one and the same thing: he arrives somewhere with every step he makes. He experiences the present moment with his eyes, his ears and the whole of his body. At the end of his journey he feels a delicious physical weariness. He knows that sound. Satisfying sleep will be his: the just reward of all true travellers.
1. Anthropologists label nowadays’ men ‘Legless’ because _________.
A. people forget how to use his legs.
B. people prefer cars, buses and trains.
C. lifts and escalators prevent people from walking.

4.What is the purpose of the author in writing this passage?
A. Legs become weaker.
B. Modern means of transportation make the world a small place.

We all like watching online videos of dogs and cats doing funny things. But if you had to decide, which of the two animals would you say you might like better? Your answer may say something about your personality.
According to a 2010 study led by Sam Gosling, a scientist at the University of Texas, US, dog people are about 15 percent more outgoing and 13 percent more pleasant to be friends with than cat people.
This is not hard to understand, since cats and dogs behave differently themselves. “Cats will occasionally engage in social activities, but usually after only a few minutes, they will abandon the game. Dogs, on the other hand, will often engage in play, like fetching a thrown ball, for hours at a time,” said Modern Dog Magazine.
Although cat people are less social, Gosling’s study showed that they are 11 percent more open-minded than dog people. They usually like art, adventures and unusual ideas. They also have more imagination and curiosity. But dog people are more likely to stick to old beliefs and traditional interests.
However, their love of a free lifestyle also means that cat people dislike making plans. They just follow whatever ideas pop into their heads without planning ahead. But dog people are different. They usually have strong self-control and like to carry out their plans.
Despite these big differences between dog people and cat people, there are some things that they have in common, “Both types of people consider themselves close to nature, dislike animal-print clothing, and are generally optimists,” noted Mother Nature Network.
But can personality change? Can a cat person become a dog person, or the other way around? In a study done by Stanley Coren, a scientist based in Canada, he asked cat owners: “If you had enough living space and there were no objections form other people in your life, and someone gave you a puppy as a gift, would you keep it?”
About 68 percent of them said they would not accept a dog as a pet. But when dog owners were asked the same question about a kitten, almost 70 percent said they would allow a cat into their lives.
1.According to the article, dog people _____________ cat people.
A. perform better in school than B. are more open-minded than
C. have closer friends than D. are more traditional than
2.The underlined phrase “engage in” in Paragraph 3 probably means_____________.
A. take little interest in B. take part in C. benefit from D. suffer from
3.What do cat people and dog people have in common?
A. Both of them like planning ahead
B. Both of them love travelling and adventures
C. Both of them are imaginative and curious
D. Both of them care about nature.
4.What can we conclude from the last two paragraphs?
A. Cat people are more likely to become dog people.
B. Dog people are more likely to accept cats into their homes than cat people are to accept dogs.
C. Neither dog nor cat people like to accept a new pet.
D. It is difficult to find out whether dog people or cat people will make a change.

Lots of people like a good fright at Halloween(万圣节). Yet, the most frightening thing of all about the night is that twice as many children are killed while out and about on Halloween compared to any other day of the year, according to a study by Safe Kids Worldwide. It can also be a worrying time for others, especially elderly people living alone. But many people think it’s just harmless fun.
But is it harmless fun?
Police forces across Britain are giving warnings about Halloween night. They are asking all those wishing to celebrate Halloween this year to respect those who don’t want to join in.
Some forces, like West Mercia Police, have produced “Sorry, No Trick or Treat”posters which can be downloaded from their website, and put up in windows. They want people to send them to the old or anyone who may be frightened by ghosts(鬼) knocking on their doors.
A spokesman said: “Children should not call on houses where the posters are put up, neither should they call on strangers, as this can put young people at risk and also make some house owners anxious, especially those who are elderly or living alone.”
The police want all trick or treaters to remember that disturbing other people or throwing objects at their homes or cars are all criminal offences(刑事罪). “What may start off as a bit of fun could end up with someone getting a criminal record,” they warn. “Parents may want to consider having a Halloween party at home, instead.”
Kent Police are warning young people never to go into the home of someone they don’t know—and to remember not to frighten people.
Warwickshire Police are also warning that tricks may seem like harmless fun but can cause trouble to others. They say behaviour such as throwing eggs can quickly cross the line between being anti-social and causing criminal damage. This can result in fines of £2,500 for small offences.
1.The study made by Safe kids Worldwide has found that _________.
A.kids are afraid of Halloween
B.Halloween brings people no fun
C.kids are involved in criminal offences
D.Halloween night puts some kids at risk
2.British police forces are making efforts to _________.
A.put an end to trick or treat
B.control anti-social behaviours
C.punish those who frighten others
D.make Halloween safe trouble-free
3.“Sorry, No Trick or Treat ” posters are designed to _________.
A.ask people to respect the elderly.
B.make some people free from harm
C.warn little kids to behave themselves
D.express disagreement with Halloween
