Have you noticed your life becoming a little easier? Now, when you go to a certain shopping mall, you can enjoy its free Wi-Fi there. When you want to take a taxi, you can book one with your phone. In fact, all these can be seen as the basic parts of a smart city.
The idea of a smart city was brought up by US company IBM in 2010. Generally, a smart city is a city that uses digital technologies such as the Internet to improve city planning, save money and resources, and make our life convenient. How smart can a city be? Here are great examples that we can learn from.
In 2009, Dubuque became the first smart city in the US. The city used smart water meters to take the place of traditional water meters. They can detect(探测〉water waste and leakage(泄漏)and send data to let the house owner know. The same system is used for other city resources like electricity and natural gas. This way, people know how they use their resources and are glad to help reduce waste.
Santander in Spain also gives us a look at the future. If people point a phone toward a nearby bus stop, the phone immediately shows all bus lines that serve the stop as well as their arrival times. The government organized a research team and provided an App(应用程序〉that collects data on almost everything: light, temperature, and the movements of cars and people. Opening the App near a supermarket provides immediate information on special

Mom is usually home on Sunday but this week she was going to a big golf game and I was all alone in the house. I was mad at Mom for divorcing Dad.
I kept looking at the telephone until I couldn’t stand it any longer. I picked up the receiver and dialed Dad’s number over in Bakersfield. I even remembered to dial 1 first because it was long distance. “You promised to phone me this week but you didn’t,” I said, feeling I had to talk to him.
“Take it easy, kid,” he said. “I just didn’t get around to it. I was going to call this evening. The week isn’t over yet.”
I thought about that.

“I hoped you would call, so I waited and waited.” Then I was sorry I said it.

A teenager who is preparing to go to high school has probably heard all kinds of different things about high school freshmen from his parents , fiends , or old brothers and sisters.

Donald Watson was a man who thought very much about the food he ate. He was born in yorkshire, England , in September 1910. And he died in November 2005, at the age of 95. That is a very great age. Watson explained that it was because he never ate any food from animals.
When he was a boy , Watson stayed on a farm. .He loved to see the animals. He said that they gave so much to people. And all the animals were so friendly. Then , one day , he saw a man killing a pig . He was very sad. . From then on, Watson decided that he would never again eat meat . Twenty years later he decided that he wouldn’t eat anything from animals, such as milk, cheese or eggs. He became vegan (素食主义者).
Watson formed a group called “The Vegan Society”. In its newspaper, The Vegan Society thought it was terrible and wrong to eat food from animals. At first, there were not many people who agreed with him . They thought it was crazy to do it .Most people thought it was too difficult and unhealthy. However, over time , more and more people began to agree with Watson and The Vegan Society.
People become vegans for many reasons. Watson and his friend stopped eating because they loved animals. They believed that it was wrong to hurt another living thing .
Now, people also become vegans for environmental reasons. Keeping animals takes a lot of resources(资源), including water and food. Also, in some places, people are cutting down trees to create more land for cows. By avoiding food from animals, vegans hope to protect these forest areas.

You probably know that frogs hop ( 双足跳 ). But did you know that there’s a small frog in the Pacific Northwest that bellyflops(肚子先着水)? It’s called a tailed frog.
Dr.Rick Essner, who has been studying tailed frogs for the past few years, says, “ I’ve looked at thousands of jumps and have never seen them land on their feet like other frogs.” Most of the time, tailed frogs land on their stomachs and then bring their back legs in to prepare for another jump.
Essner forst noticed these frogs because of the way they swim. Other frogs kick both of their back legs at the same time. But when a tailed frog swims, it pushes first with one leg and then the other.
To try to find out why tailed frogs bellyflop, Essner and other scientists collected and filmed different kinds of frogs. They found that all of the frogs start their jumps the same way: they hold out their legs. The change comes in the landing. Tailed frogs can't move their back legs as quickly as other frogs do. Maybe they don’t need to. Tailed frogs live around water and quickly jump into the water to escape danger.
Early frogs developed around watery areas and could jump quickly into the water to escape danger. Scientists think those frogs blended in with (与…融合在一起) the green plants on the side of the rocky rivers, just like today’s tailed frogs. “Iwould guess that other animals would have problems detecting them, ” explains Essner. When other animals find those early frogs, the frogs could jump into the river. They didn’t need to continue hopping.
Tailed frogs and other kinds of frogs went their own ways about 200 million years ago. Tailed frogs stayed by rivers. Other kinds of frogs moved to places where new hopping skills allowed them to survive. What’s special about the detailed frog ?
A.It has a long tail |
B.It jumps on one foot |
C.It stars its jump differently |
D.It lands differently from other frogs. |
Why do tailed frogs bellyflop?
A.They have never left the water to live . |
B.They have trouble in holding out their legs |
C.Their back legs can’t catch up while jumping.. |
D.Their front legs develop better than the back ones. |
The underlined word “detecting” in Paragraph 5 means “______”.
A.eating | B.killing |
C.using | D.discovering |
When they are in danger, the detailed frogs would _________.
A.jump into the water for protection |
B.hop around quickly |
C.hide in the green plants near the river |
D.jump into the rock |
