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. 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. 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 offers.

From a plane we can see the fields, cities, mountains or seas below. If we go into space, we see more and more of the earth. People and man-made satellites have been sent out into space to look at the earth carefully and people have learnt more about the earth in the last few years.

The sea looks very beautiful when the sun is shining on it. But it can be very terrible when there is a strong wind.The sea is very big. It nearly covers three quarters of the earth. The sea is also very deep in some places. There is one place and at that place the sea is about 11 kilometers deep. The highest mountain in the world is about 9 kilometers high. If that mountain was put into the sea at that place, there would be still 2 kilometers of water above it!

In most parts of the sea, there are many kinds of fishes and plants. Some live near the top of the sea. Others live deep down. There are also a lot of small living things, and lots of fishes live by eating them.

The sea can be very cold. When people go down, the sea becomes colder and colder. Only some men can go down into the deep sea. But, in 1970, five women scientists lived in the deep sea for fourteen days.

A

  There were three big fish in the lake．One of them，Demo，was wise；another one，Jimmy，was half-wise；Martin，the third one，was stupid．
Some fishermen came to the bank of the lake with their nets．The three fish saw them．
Demo decided at once to leave，to make the long and difficult trip to the ocean．He thought，"I won't discuss with these two about this．They love this place so much that they call it home and will stay on．How silly they are!They still haven't realized we are in great danger now．Their ignorance will cost them their lives．"
Seeing the wise fish had left，Jimmy thought，"My guide has gone and now I've lost my chance to escape．"He felt sorry for it and then thought，"What can I do to save myself from these men and their nets？Perhaps I should pretend（假装）to be already dead，giving myself totally to the water．"So he did that．He went up and down with the water，helpless，within arm's reach of the fishermen．
"Look at this!The best and biggest fish is dead．"One of the men lifted him by the tail，and threw him up on the ground．He rolled（滚动）over and over and moved secretly toward the water，and then，back in．
The third fish was aimlessly jumping about，trying to escape with his speed and cleverness．The net，of course，finally closed around him，and as he lay in the hot frying-pan bed，he thought，"If I get out of this，I'll never live again in the limits of the lake．Next time，the ocean!I'll make it my home．"

Today, we may see all kinds of high-technology products in our lives. Wearable technology is nothing new. Google Project Glass (谷歌眼镜) and smart watches are now as common as shoes and glasses. In the not too distant future, it’s likely that our clothes will be almost as smart as our phones. But what’s the advantage of Internet-connected clothing?

Imagine when you put a jacket in the washing machine, a chip (芯片) in the jacket puts the machine on the right laundry setting, making life just that a little bit easier. The clothes have the ability to help us find out more information about the product, such as how it was designed, where it was made. And it isn’t just a dream. Internet-connected clothes are already being made but they need time to be popular.

 Two leading companies in clothing making hav created a jacket with two-bar-code(二维码). The code in the chip gives the user a number of special droits such as going to some clubs, special menus at certain restaurants and tickets to some fashion shows.

But Internet-connected clothing isn’t the only way combining with technology. It will also change the way we buy clothes. Through smart computers in our homes, our shopping needs will be known in advance and taken care of. For example, before you realize you’ve run out of dresses, your favorite online sellers have already recordered some new ones for you based on your repurchasing (再次购买) patterns.

 With Internet-connected clothing, it may soon be taht when we buy clothes, we hardly have to think about anything at all.

I was walking in the street when a piece of beautiful music came to my ears. I saw some-one   (1)  some rubbish and walk to a truck which was collecting rubbish   (2)  . As soon as the people nearby hear the music, they   (3)  go out with their rubbish and throw it in, It’s a   (4)  way to help keep our city clean. Protecting our environment is very important.  (5)  you live, you can do something useful in or around your neighborhood.   (6)  , we have done something to improve the environment. For example, we have collected  (7)  paper or bottles for recycling and we have planted   (8)   trees or flowers in or near our neighborhood. If   (9)   makes a contribution to protecting the environment, the world will become much more  (10) .

 Crying is the sign of the rawest of human emotions. We cry when we can’t hold inside what we feel any more. We cry when we’re at our best, and when we’re at our worst. By we, I mean all of us. Men included.

  But we never see other men cry. In no western culture has it ever been acceptable for men to shed(流泪）more than a single tear, and even then it’s reserved for grand victories, defeats and deaths. Dutch research suggests that women cry between three and five times more than men. Generally men and women cry over the same things一deaths, break-ups and homesickness, primarily, but researchers believe that men cry more often than women when it comes to positive events.

  I want to admit，Iˈm a bit of a cryer. However,having never really experienced deaths in my life, a few weeks ago I experienced what it means to really, truly, pour my heart out in tears.

 See, my dog一and 24/7 companion一was killed by a car right outside my house. Being a witness to this painful event left me in shock for a good hour, but then the floodgates opened. Over the next 48 hours, I might have cried 20 times. Once or twice Icrouchedon the floor with my head in my hands and tears were the only outlet.

 It is suggested in the book Adult Crying:A Biopsychosocial Approach that there’s a certain pleasure in crying. It helps ease stress when there is no other way to express ourselves.

 In those days after my dogˈs death，I remember thinking，“ I’ve got to stop this crying”. It felt unmanly. It felt like a sign of weakness. Iˈve since realized that tears are for everybody;theyˈre not gender-specific. They show we have sympathy, allow us to get rid of stress and just feel.
