As we know, the time of 5G technology (技术) is coming. Recently, there’s a lot of information about 5G. But what is this technology and how might it bring to our lives?

What is 5G?

5G means the fifth generation mobile networks (网络), a better technology than 4G. And we know, 4G comes after 3G and makes the network run faster than 3G.

When will 5G come to our life?

Before we can all use 5G, there must be a new system (系统) for 5G to work. In the USA, some cities will first use 5G this year. Experts say it will take a few more years or even longer to reach every place. In China, a few cities are using 5G now. And more and more cities will join this group. Next year, 5G will become national, even in the countryside.

What can 5G do?

Experts say 5G will help to build future“smart cities ” with the help of sensor networks (传感器网络). Such networks will be able to help the police with the traffic. They can help us know what’s happening in our homes when we are at work. They can even help to make it possible for doctors to perform an operation (手术) far away.

?

In the future, more information and more kinds of information will be travelling across 5G networks. Much of the information could be about persons, businesses or government organization (政府组织). So we can see, the wider use of a 5G network means any mistake of the system would cause serious results. Then they may bring problems of public security(安全) and world economic (经济) activity.

I travel a lot,and I find out different “styles” of giving directions every time I ask “How can I get to the post office?”

In Japan,people use landmarks(地标)in their directions because most streets don't have names.For example,the Japanese will say to travelers,“Go straight ahead and turn left at the hotel.The post office is across from the bus stop.”

In the countryside of the American Midwest,there are no towns or buildings in many places.Instead of landmarks,people will tell you directions and distances.In Kansas,for example,people will say,“Go north two miles.Turn east,and then go another mile.”

People in Los Angeles,California have no idea of distance.They measure(测量)distance in time,not miles.“How far away is the post office?” you ask.“Oh,” they answer.“It's about five minutes from here.”

It's true that a person doesn't know the answer sometimes.What happens in such a situation?A New Yorker might say,“Sorry,I don't know.” But in Yucatan,Mexico,no one answers,“I don't know.” People believe that “I don't know.” is impolite.They usually give an answer,often a wrong one.A tourist can get very,very lost in Yucatan!

1.Why do Japanese people use landmarks in their directions?

If you want a pen friend, what should you write in your first letter?

*Your basic information, such as your name, age and where you live.

*How you found his/her name and address. For example, I saw your name in Kids' magazine. . .

* _____________________________ This gives you a lot to write about and lets your pen friend see if you two share the same interests. You may write, "I have a dog named Einstein. He is very naughty.

*Be specific (详细而精确的). Don't say you like watching movies. Tell them what movies you like. Say something like "I watch a lot of Disney movies and my favourite one is The Lion King. . "

*Ask questions so that he/she can answer. For example, I like Jay Chou very much. Who's your favourite pop star?

*Never demand that your pen friend write you back. It's rude. Try to say something like Looking forward to hearing from you and I can't wait to hear from you soon to invite them to write you back.

*Make sure you close your letter with something friendly. For example, Your New Friend", “Yours” or Cheers". Don't end your first letter with Love", You just get to know each other. and the word may scare (是受惊吓) your new friend!
