If you look at the top of your phone, you'll usually see a little symbol that says 3G or 4G. The "G" stands for the "generation" of your mobile network. But these symbols will become things of the past after 5G fully arrives.
On March 30th, 2019, Shanghai vice-mayor Wu Qing made the first 5G video call on a Huawei Mate X smartphone, CGTN reported. Shanghai has also become the first city in China to start testing 5G networks.
Now, 4G takes about 100 to 200 milliseconds(毫秒)to send and receive data(数据). But 5G will get it down to 1 millisecond or less. This big change will not only make our mobile Internet faster. It can be used in many other ways as well.
For example, 5G will help to make self-driving cars safer. Today's self-driving test cars have one problem-lag. When the car "sees" an obstacle(障碍物), it sends this information to a data center and receives instructions. However, it takes time to send and receive this information. With this kind of lag, the cars might crash(撞击)because they don't receive instructions in time. With 5G, this lag will be greatly lowered, making the cars safer, according to CNN.
5G could also be used to power the Internet of Things(IOT). This refers to a large online network that connects all things and people. Fast Internet speeds will be the key to developing this technology. For example, with IOT under 5G, your refrigerator could automatically(自动地)place an order online for eggs when it finds that there are no eggs left inside.
All in all, 5G will shape every type of technology that it touches. And you won't have to wait too long for that to happen.
What can little money do? It's worth thinking it over.
A few weeks ago, I got $120 from a friend in a Smile Group. He asked me to do good things with the money. Since then I have used the money to help strangers, and raised a lot of smiles.
One day I was in a shop, looking at the second-hand books. It happened that the book shelves (架子) were next to the toy shelf. I noticed that a poorly dressed woman standing behind me. A girl about 3 years old came over to my shelf. At once her attention was caught by a toy dog. She spoke to her mother and her mother asked the shop owner how much it cost. The answer was $ 3. Then she said "no". The child said nothing. Maybe "no" was not new for her, but she couldn't keep the disappointment away from her face.
I had a total of $ 5. I put the money in the mother's hand and said, "Buy her a book, too." I didn't wait to see the end. I walked out of the shop.
The money the friend gave me was to help me find happiness in the world. Was there any better way to get so much happiness with so little money?
His carelessness the accident.
is here, let's begin.
My father smokes drinks wine.
, he is wrong this time.
, we often take a trip to the countryside.
It was a lovely spring afternoon. My classmates and I were playing1on the playground when I let out a cry, "Ow! Ow! Something in my shoe is biting me!"
Everyone was shocked by the cry. They took me into a classroom and were about to take off my shoe. "Which foot is it?" one asked. "Let2have a look."
Suddenly, I remembered the holes in my socks. My family was3poor during those years that my parents couldn't buy me good socks. Instead, I wore welfare socks,4cost only a little, but those cheap socks didn't last long. They soon had holes at the bottom.
I refused5off my shoes. I couldn't stand others seeing the holes in my socks. I tried to hold back my tears. Yet, each time the thing in my shoe bit me, tears raced down my face.
My teacher, Miss Diane, hurried into6classroom. "What's wrong?" she asked.
"Something is biting her right foot,7she doesn't allow anyone to take off her shoe," one of my classmates answered.
Miss Diane lived next door to me. She knew everything8my family. She put9hands on my shaking shoulders and looked into my painful and hopeless eyes.
"Oh, yes, it 10be a sock-eating ant," she said, as if she had already seen the thing inside the shoe. "I remember 11I had a bite from one of those ants. By the time I got my shoe off, it had eaten almost the whole bottom of my sock." My classmates nodded while they were listening to the teacher carefully, although they all looked a little12.
Miss Diane took off my right shoe and sock and13them over the dustbin. Two red ants fell into it. "Just what I thought. The ants have eaten part of her sock." When she stroke an alcohol (酒精) cotton ball on the bites, she added, "you are14brave girl to take so many bites."
The alcohol felt cool on the bites and a little girl's pride15by the "sock-eating ant" story.
Li Ming his homework after supper?
After experiencing all of this, I learned a lot. I began to .
