【題目】 How has technology made your life easier? When you go to a shopping mall, you can enjoy free Wi-Fi there. When you want to take a taxi, you can book one with your phone. 【1】 The idea of a smart city was first suggested by tech company IBM in 2010.【2】There are many examples in our lives, such as 5G networks and the “internet of things”, they are used to improve urban planning, save money and resources (資源), and make our lives more convenient.

Cities like Boston, Amsterdam and Copenhagen are already using smart technology to improve public services 【3】In Amsterdam, traffic is monitored（監(jiān)測(cè)）and adjusted according to real-time data gathered from sensors around the city. There are fewer traffic jams.

Smart cities will allow us to save resources. By using sensors and 5G networks to check the usage of water, gas and electricity, city managers can figure out how to use these resources more efficiently. For example, water and gas pipes (管道) could remind repair workers when there is a leak (泄漏).【4】

Of course, it will take time to build the smart cities of the future. But since we’ve already seen successful examples, it won’t be long until more cities join in. 【5】

A.In the US cities of Boston, smart trash bins can sense how full they are and tell workers when they need to be cleaned.

B.In fact, all of these things can be seen as the first building blocks of a smart city.

C.Tech Republic estimates(估計(jì))that by 2050, about 60 percent of people worldwide will live in smart cities.

D.Air pollution could be more closely monitored, too.

E.A smart city is a city that uses digital (電子的) technology.

【題目】請(qǐng)仔細(xì)閱讀下列短文，并根據(jù)所讀的內(nèi)容在文章后表格中的空格里填入一個(gè)最恰當(dāng)?shù)膯卧~。注意:每個(gè)空格只填寫(xiě)1個(gè)單詞。

Have you ever regretted what you did in the past? Anyone around you will have no difficulty in telling his regrets. As we get older, we look back and wish that we had made better choices.

What can we do to prevent this happening?

Make better plans

If you begin to do something, you need to make a plan before doing it. The earlier, the better. You will know what comes first and what comes last. You'll also know what you should do and what you shouldn't do. If changes happen, you can have more time to deal with them.

Live a more active life

You can go around more often. More outdoor activities can keep you relaxed. You also need to be kind. “Thank you”can bring a smile to someone's face. Learn to say “sorry'” and don't be angry with others.

Find the right friend

A friend may make your life and he or she can break your life as well. So you need to think twice when you choose a friend. Good friends will always better your ideas.

When you have problems, ask others for help. That little help may get you good results.

Never fear failure

Everybody fails. Even the greatest person failed. We should not fear failure, because failure is not the end of the road. We must take failure as a chance to learn and improve ourselves.

Life is good. We don't have to live in our past, but we do hope that we can plan better, live better, and work better when we have the chance to do so.

【題目】 “Smombies”, people walking while staring at their mobile phone are getting attention of the public. To make them pay more attention to things around them in order to avoid serious accidents, the government of a small German town has come up with a solution，that is，fixing traffic lights in the pavement to make them noticed by people who keep looking down at their phones.

The safety measure was decided after two people in the town of Augsburg were recently hit by buses as they crossed the street without looking up from their phones. Officials in Augsburg decided to act，fixing ground-level traffic lights at two bus stops last Tuesday. The lights flash red whenever a bus is coming.

“We realized that many people don’t pay attention to traffic lights,”said Tobias Hermes，a city official. “So we decided to have unusual traffic lights. The more we have，the more probably people will notice them.”

Some Augsburg people seem to be quite happy with the idea. “I think it does have a point,” Jack Smith said，“We always see young people these days running over red lights，which makes it clear that we have to take action to stop this.”

Others，however，don’t think it necessary or helpful and they are against this idea. “I find it scary that mobile phone users are so lost in their phones that they can hardly find the lights on the pavement.” One person told the local paper.

But do these pavement lights really work? “To be honest,I didn’t even notice it,” one teenager who was interviewed said ,“Maybe it’s useful at night，but I didn’t realize it was there until just now.”

Arguments like that are still going on. Whether more such traffic lights will be fixed is till under discussion. Whatever the result is，something must be done to cut down the number of“Smombies” as long as we don’t want to see accidents caused by them again.

【1】What can we learn about “Smombies” from the article？

A.They look away from their mobile phones to keep safe when necessary.

B.They fix their eyes on their mobile phones even while crossing the streets.

C.Most of them get hit by buses.

D.They are mostly teenagers.

【2】What does the underlined word in Paragraph One mean？

A.人行道B.盲道C.護(hù)欄D.地下通道

【3】Which of the following will Tobias Hermes support？

A.Buses are the main cause of traffic accidents.

B.Bus lights should flash red while buses are running.

C.The pavement-fixed lights will save people’s lives.

D.The increasing number of traffic lights will get more people’s attention.

【4】What’s the best title for this text？

A.Ground Traffic Lights for people looking at Mobile Phones

B.A Good Way to Educate People to Obey Traffic Rules

C.Ground Traffic Lights Are Very Useful

D.The Serious Problem of Traffic Safety
