2 . Imagine a world where you move around in front of a personal computer in your own sound space. You listen to your favorite songs, play loud computer games or watch a movie — all without other people hearing the sound and without headphones.

That is the possibility presented by “sound beaming”, a new technology from Noveto Systems, an Israeli company. On Friday, the company introduced a desktop device that sends sound directly to a listener without the need for headphones or a special receiver.

Noveto Systems gave The Associated Press (AP) a chance to test its SoundBeamer 1.0 before its introduction. The AP’s Louise Dixon writes that listening to the device is like something from a science fiction movie.The sound seems so close that it feels like it is inside your ears while also in front, above and behind them.

Noveto expects the device will have many uses. Office workers could listen to music or conference calls without others hearing. People could play a game, a movie or music without waking up others in the same room. Because the device does not use headphones, it is possible to hear other sounds in the room clearly.

The device uses a 3-D sensing module that finds and follows the ear position of the listener. It sends ultrasonic waves (超声波) to create sound pockets by the user’s ears. The 3-D method creates sound on all sides of the listener, therefore the listeners feel completely transported into the scene.

By changing a setting, the sound can follow a listener around when he moves his head. It is also possible to move out of the sound beam's path and hear nothing at all.

While the idea of sound beaming is not new, Noveto was the first to launch the technology.

According to the chief executive officer Christophe Ramstein, a “smaller” version of the device will be ready for release to consumers next year.

3 . I had planned a tour in New Zealand and when I finally visited the country last year, I simply fell in love with it.

New Zealand is a nature lover’s paradise. Wonderful scenery, pollution free, good climate, challenging activities…what more can one ask for? No skyscraper in cities at all. A four or five-storied building is a high and huge one here. The West Coast beaches attracted me most. Sitting on the sand, listening to the wind, watching the fantastic tiding, we were exposed to a wild and pure picture.

We rented a car and drove throughout the South Island. You can reserve one through the Internet. It is quite convenient to get and return the car. We started our driving in Christchurch and stopped in Dunedin seven days later.

New Zealanders call themselves Kiwi（几维鸟）. This simple and kind species exists merely in this island. That is just what a New Zealander has.

The engine once stalled suddenly. However we tried, it refused to work again. There was not even one car passing by. Just then two bikers appeared and offered help. Finally the car could move. Another time we lost the car key. We searched the way we walked inch by inch, hoping to find, but failed. All the things were in the car. We went to the Lost-and-Found to try our luck. The gentle policeman gave us all keys found within one hour to check. Our key was lying there!

That is New Zealand. A simple but splendid place!

4 . So many things can keep you from seeing your loved ones in person, from busy schedules to long distances. Fortunately, thanks to modern technology, the people we miss are often only a phone call or text message away. But if you’re someone who prefers typed out messages toverbalones, you may want to reconsider. According to science, if you want to feel more connected to the people you're talking to, you should call them instead of texting.

A new study, published in the Journal of Experimental Psychology, found that communication including voice, like a phone call or video chat, created stronger social connections than communication through typing, like text messaging or e-mailing.

In the study, researchers used various experiments to judge connectedness. In one, they asked 200 people to predict (预测）what it would be like to reconnect with an old friend by e-mail or by phone. Although people expected that a phone call would get them more uncomfortable, hearing someone's voice actually made the experience better.

In another experiment, the researchers had strangers connected by either texting, talking over video chat, or talking using only audio (音频）.They found that both forms of voice communication—whether video or audio only—made the strangers feel significantly more connected than when they communicated by texting.

Sabrina Romanoff, a psychologist, says people prefer to text or email instead of calling because of convenience. In reality, texting can make it hard to determine the true meaning behind a conversation. "A phone call is actually more convenient when considering the net effects of the message,” she explains. “Each party is present, and therefore, able to understand the meaning behind the content without figuring out the endless possible meanings behind words.”

5 . China will have the most 5G connections of any nation by 2025, according to a new study, while Europe will fall behind Korea, the United States and Japan in terms of 5G penetration(渗透)by that year.

5G is the fifth generation of network technology. It is expected to bring unbelievable speeds to Internet users, with some operations running 10 times faster than on 4G networks. 5G is also expected to unlock the potential in a lot of new services, including artificial intelligence, science of robots self-driving cars, and the Internet of things.

The GSMA said that China's three major mobile operators-China Unicorn, China Mobile, and China Telecom-are already moving ahead with 5G networks. While most nations will have 5G by updating existing foundations, the study noted that China plans to build part of its 5G networks.

One of the most distinguishing(显著的) factors between Chinese mobile operators and those in the rest of the world is the intention to erect the new and independent 5G networks. That is, China is determined to build a completely advanced 5G. The high cost underlines China's seriousness about paying whatever it takes.

Korea will lead the world in terms of 5G penetration in 2025, when 66 percent of the nation's total connections will be 5G, according to GSMA. This compares to 50 percent in the US, 49 percent in Japan, 36 percent in China, 30 percent in Europe, and a global average of 18 percent. Out of the five economies leading on 5G, Europe will have the lowest participation in 2025, as the area is moving more slowly in having its 5G networks.
