   Technology has enabled people to connect fast and across vast distances. 【小题1】 Therefore, it is important to find ways to communicate better, while we are still keeping pace with the demands of the modern day.

Cut back on texting. Texting is a good way of keeping in touch and communicating with another person if calling him is not possible. Unless you can’t help it, give up the habit of texting — while walking, eating or driving — because texting is not real communication. 【小题2】 Calling is a great way of enhancing conversations because it’s more direct, with a greater chance of successful communication.

【小题3】 We are more willing to spend time on Facebook than actually leave our desks and have a conversation with the person working right next to us. A good way of improving real-life communication is to log off or keep yourself away from social media.

Meet people face-to-face. The next time you want to open Facebook to chat with a friend, call him up and meet him instead. 【小题4】 Take time to meet the person who matters to you and you will get a kind of communication and relationship that staring at a screen just can’t provide.

Technology is a tool. It is worth remembering that technology is only a tool we have. 【小题5】Use social networks to find people, to reconnect with friends, to support a cause and to contribute to the bigger picture in a more real manner.

Controlling Anger

Becoming angry is something beyond the control of people.【小题1】 Becoming angry can do a lot of damage，both mental and physical. However，there are methods for discovering how to control anger and not to suffer later.

·【小题2】 The moment you feel there are chances for you to become angry，get away from those circumstances（环境）.In fact，there can be no better judge than you，for discovering what it is or who it is that makes you become angry，and then at that moment choosing to think about something else that can lighten your feelings.

·Keep a check on your breathing.【小题3】 By controlling the process of breathing，you can actually slow down your anger greatly. You can count till three as you breathe in，hold it for 3 seconds and again count till three while breathing out. You have to concentrate on the count as you do this and repeat this for as many times as required.

·【小题4】 For example, if you’re experiencing road rage while driving，you can choose to tell yourself that the person who overtook you by a vehicle was in a hurry as a result of some emergency and appreciate the fact that nothing major happened to your car. Repeat this form of self-talk to yourself every time you are in the middle of such an angry situation.

·Look for the support of other people.【小题5】 It needs to be clear right at the beginning as to why you are discussing your concerns with that individual. Let the other individual know what you want from him or her. After you’re done with your part of discussing about the circumstances，chances are that you’ll feel much better than before.

   Self-driving cars are so popular that the University of Michigan has even established a town called Mcity to allow car manufacturers to safely test their autonomous cars.

While Mcity can be used to simulate（模拟）many real-life road conditions，it can't help test gestures drivers use to communicate their intention（意图）to other drivers，pedestrians or cyclists. To find a solution，US car manufacturer Ford，with researchers from Virginia Tech，at the beginning considered using text as a way to communicate the car's intention，but decided it would probably not work universally. The option of using symbols was also rejected，because research shows that a majority of people do not have a good understanding of what they mean.

Finally, the researchers settled on light signals. A white light warned that there were no humans in the car. A slow blinking one indicated that the car was coming to a stop, while a rapidly flashing light cautioned passersby that the car was about to speed up.

Then came the big challenge—testing the signals on real roads. "We needed to try out this new lighting to communicate the intention of the vehicle, but if you've got a driver behind the seat, you still have natural communication between humans," said Andy Shaudt, who led the research team. "So we needed to make it look like a driverless car."

The team designed a car seat costume（戏装）that the driver would wear to cover his or her face and upper body. Of course，the drivers could see very clearly. The researchers then equipped the car with cameras to capture human reactions to a light bar，which flashed one of the three signals when appropriate. Six drivers，all keeping their hands low on the wheel so as not to be noticed，took turns to test driving the car through the busy streets.

The overall reaction to the flashing lights was very encouraging. Who knew costumes could be useful for more than Halloween？

   Could cities that float on the sea solve the problems caused by floods and provide food for the world?

Some scientists think so. The idea is already being tested and they believe that floating cities will provide more homes for a growing population, without having to use land needed to grow food. And they believe floating areas will allow more food to be grown, so that no one in the world is in hunger.

In some places, cities that float on the sea are already being planned. A company in the Netherlands called DeltaSync thinks that sea cities will save the world, with more than one in ten people living in them.

They say sea cities can solve many of the problems the world faces in the 21st century, like not having enough land, more and more people needing homes, fossil fuels (矿物燃科) running low and the increasingly serious problems caused by floods.

DeltaSync says building in the desert is not possible because there is no enough water and that developing ways for people to live in space is still too expensive. So they believe the answer is our oceans, which cover over two-thirds of the Earth’s surface. Their plans for floating areas include using algae (藻类) to produce fuels and food.

More than a quarter of the land in the Netherlands already lies underwater and scientists there have spent years trying to find ways to deal with it. In the city of Rotterdam they already have floating homes.

Bart Roeffen from DeltaSync says, “We have plans for neighborhoods including roads and, in the end, I believe we can build floating cities on the sea.”
