1 . Slowly but surely, we’re moving closer and closer to 5G world. From smart-home security to self-driving cars, all the internet-connected devices in our life will be able to talk to each other at lightning-fast speeds with reduced delay. Objectively speaking, the fastest 4G download speeds in the US top out at an average of 19.42Mbps. But by comparison 5G promises gigabit (千兆) speeds.
“5G is one of those heralds (使者),along with artificial intelligence, of this coming data age.” said Steve Koenig, senior director of market research for the Consumer Technology Association. The self-driving vehicle is a great emblem of this data age, and that is to say, it is a sign of time, because with one single task, driving, you have massive amounts of data coming from the vehicle itself, and a variety of sensors are collecting a lot of information to model its environment as it moves. It’s pulling in data from other vehicles about road conditions down the lane. It could be weather information, and also connected infrastructure (基础设施) construction. There’s lots of data behind that task, which is why we need the high speed.
And virtual reality glasses and headsets haven’t yet broken the mainstream, but tech companies are joyfully betting that these devices will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to assist — or even replace — smartphones.
Ericsson stated at February's Mobile World Congress how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components, the glasses could rely on hardware for processing power.
But don’t get too excited. There’s still a lot of work to be done in the meantime, including various trials to make sure the radios play nicely with hardware and infrastructure construction so 5G isn’t concentrated only in big cities.

2 . The King received news one day that a group outlaws were committing some wrong and cruel acts on a distant border of the kingdom.
The news angered the King. He quickly gathered his army and started off for the distant border, leaving his kingdom unguarded and without a ruler.
On their long march, the King and his army made camp for the night wherever they could. One rainy day they stopped in a forest, seeking shelter under the trees. They unsaddled（卸鞍） their horses and steamed some peas, which they fed to their steeds(战马) in long narrow containers.
A monkey in a tree nearby saw the horses being fed, and he came racing down, fille9d both paws with peas, then climbed quickly up to a branch and settled down to eat. But as he opened one paw, a single pea fell to the ground. Without hesitation, my monkey jumped from his branch to hunt for the lost pea, and in doing so，he dropped all the other peas in his paws.
The King observed this foolish monkey and was greatly amused. He turned to his minister and asked: "Friend, what do you think of this monkey who would give up so much to retrieve so little?" "That is the way of the foolish," replied the minister, "they will give up much that is certain for a little that is uncertain." Then he added, "And we, Great King, are we not like the monkey in the trees. To gain so little we neglect (忽略 ) so much exactly like the monkey with its pea.
The King understood the blame and realized how very foolish he had been himself to leave his kingdom unguarded. He gave out orders to his men, and he and his army returned at once to their country.
