Do you know 5G? It is the fifth generation(代) of mobile network technology. These new networks are coming.
China just issued commercial licenses(发放商用牌照) for 5G on June 6th. This means that China’s telecom companies were soon able to offer 5G networks for mobile phone users.
Each mobile network generation is faster and more powerful than the one before it. 1G let us talk to each other. 2G let us send messages. 3G gave us data and the Internet. And 4G made all of these things faster. What’s special about 5G?
5G has a very short delay between sending and receiving information. Now, 4G takes about 100 to 200 milliseconds(毫秒) to send and receive data. But 5G will get it down to 1 millisecond or less.
This big change will not only make our mobile Internet faster, but also deeply change our lives. Read on to find out how.
5G + entertainment
5G networks are about 100 times faster than 4G. This means you can download a movie in seconds using 5G.
5G + transportation
5G will also bring us safer self-driving cars. These cars can send signals(信号) to each other. They also talk to traffic lights and road sensors(传感器). 5G will allow cars to react even faster than human drivers.
5G + smart homes
5G also makes the Internet of things possible. Internet of things is a large network that connects everything to the Internet. Smart homes are part of it.
For example, if the sensor feels the air becoming dry, a smart sprinkler(洒水器) could water your plants by itself.

【推荐2】①Can plants grow in the moon soil(土壤)? Scientists at the University of Florida in the United States seemed to find the answer.
②The moon soil brought back by astronauts on the moon was protected well because it was important to the planting work in a lab. Scientists had always hoped to do a test about the moon soil. Finally, they got the chance. This group of scientists planted some seeds(种子) in the moon soil. What made these scientists surprised was that they sprouted and began to grow.
③Scientists also made some fake(仿造的) moon soil from the earth and put the same seeds into it. The result was that the plants in the moon soil grew more slowly than those in the fake moon soil. According to scientists, the moon soil was full of things that are not good for the plant’s growth. Also, we know that the moon soil is not fertile(肥沃的).
④How to help improve this situation? One possible way was to choose the soil from the younger geological(地质的) areas on the moon and to create a better planting environment.
⑤The research could not only help to study the future of the moon but also gave people a lesson of planting things in some difficult environment on the earth. The research also made scientists think about whether it was possible to build a “greenhouse” that is good for the plant’s growth on the moon in the future.
⑥In a word, scientists believe more good things are going to happen on the moon in the future.

Do you have the experience of taking music lessons against your wishes? Perhaps you have complained about it because you thought it took you much playtime. But now you’d better thank your parents for their time and money spent on your musical training. A recent study suggests music lessons can make children have better memories than their peers (同龄人).
The Canadian study showed that after one year of musical training, children did better on a memory test than those who didn’t take music lessons.
The researchers made the children aged between 4 and 6 into two groups — one group of children took music lessons outside school, and the other didn’t take any musical training. In one year, they took four tests in different times. The results showed brain development changes at least every four months.
The children taking music lessons not only did better in musical listening but also made faster progress in other ways, such as reading, writing, math and IQ.
People say music is the good medicine for a broken heart. Now it seems music can also help us to improve our memories. We are sure to find more and more in the wonderful world of music.

Are you a little shy when it comes to raising your hand in class? If so, that's totally normal. We've been there. With all attention on you, it can be so scary to speak up.
However, if you can break through your fear, we promise you can benefit (受益)a lot. According to a government study, some students are falling behind because they're too shy to put their hands up when a teacher asks a question. So try to raise your hand!
To start with, you'll realize the power of being wrong. Nobody is right all the time. Your teacher will be happy to see your participation and won't punish you for being wrong. He or she will explain why you're wrong. You'll learn something new. Chances are, other students think the same thing as you, but don't speak up. Not only do you help yourself, but you help your shy classmates, too.
Besides, your teacher will know you're interested in learning. Participating in class shows that you are not falling asleep behind your textbook. This is beneficial to you and your teacher. Your teacher will appreciate your interaction (互动) during the lesson and will remember your enthusiasm(热情)The next time you're one point away from an A+.
What's more, you'll have fun discussing with your classmates. When you and other classmates are raising hands to answer questions, it makes the class more interesting and allows you to actively engage with the lesson. Your teacher doesn't have to stand in the front of the room talking nonstop for a long time. Class time will fly by and your mind won't be wandering to the clock every 5 minutes.
Most importantly, you'll know that you've actually learned the material. One of the best ways to prove that you actually know something is by talking about it. Speaking up in class shows that you are trying to understand or have understood what you've been taught.
Don't be shy or afraid to raise your hand in class. Nobody is judging you. Seriously. It'll finally pay off?

【推荐3】I Remember, I Remember
by Thomas Hood
I remember, I remember,
The house where I was born,
The little window where the sun
Came peeping (偷窥) in at morn;
He never came a wink (眨眼) too soon,
Nor brought too long a day,
But now, I often wish the night
Had borne my breath away (夺走)!
I remember, I remember,
The roses, red and white,
The violets, and the lily-cups,
Those flowers made of light!
The lilacs where the robin (知更鸟) built,
And where my brother set
The laburnum on his birthday,
The tree is living yet!
I remember, I remember,
Where I was used to ________,
And thought the air must rush as fresh
To swallows (燕子) on the wing;
My spirit flew in feathers (羽毛) then,
That is so heavy now,
And summer pools could hardly cool
The fever on my brow (眉毛)!
I remember, I remember,
The fir trees dark and high;
I used to think their slender (细长) tops
Were close against the sky:
It was a childish ignorance (无知),
But now this is little joy
To know I'm farther off from heaven
Than when I was a boy.
