How do you study each day? You may answer it in one second: have classes at school, take notes and do homework. Feeling a little bored? There are other ways that can make learning interesting and varied. It's called digital learning.

Digital learning is a way to help students learn by using the Internet. There are three important kinds of digital learning. Apps are computer software applications (应用). People can download them on their mobiles. The other two kinds are social networking services, including weibo and WeChat and websites. Every one of them is like your teacher. They help you master what you learn at school.

Compared with traditional learning ways, digital learning has its advantages. Digital learning is also varied. It covers almost every school subject. More importantly, it always offers students the newest resources (资源) to learn from.

Digital learning is also personalized. You can choose what you like to learn. If you don't master what you have learned at school, you can learn again through digital ways.

However, digital learning also has disadvantages. When you use digital ways to learn, you've got little chance of talking with teachers and classmates.

    In old times，man considered lightning to be one of the great mysteries（神秘事物）of nature．In fact a single flash of lightning 1.6 kilometers long has enough electricity to light one million lamps．
    The American scientist，Benjamin Franklin，was the first to suggest that lightning is in fact electricity formed between the earth and clouds high above．It happened in 1752．In the same year，he also built the first lightning rod（避雷针）to protect buildings from being struck by lightnings．
    Modern science has discovered that lightning is very strong and powerful．A lightning between a cloud and the earth may be as long as 13 kilometers，and travels at a speed of 30 million meters per second．Scientists have the opinion that there are about 2000 million flashes of lightning per year．In the United States alone，it kills almost one person per day．
    The safest place to be in during an electrical（电的）storm is a closed car．Outside，one should go close to low ground for cover and not stop under a tree．Also one should stay out of water and away from metal fences．Inside a house people should keep away from open doorways and windows and not touch wires or metal things．

Have you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that aren't very smooth rub together to make heat energy. The faster you rub two things together, the more friction (and heat) you can make. Let's discover friction!

WHAT YOU'LL NEED:
● Soap           ● Water          ● Your hands!
WHAT TO DO:
1. Make sure your hands are dry.
2. Rub your hands together until you feel the heat of your hands.
3. Now, use soap and water to get your hands very slippery (滑的).
4. Try to make friction happen while your hands are slippery.
5. Please write down what has happened.
LET'S TALK!
    Friction is an energy that happens when two things rub together. When friction happens, it makes heat! When your hands are slippery, they won't make very much friction and your hands won't get so hot.
DID YOU KNOW?
1. Friction happens when you stop your fast running bike.
2. Ancient people made fires by rubbing two pieces of wood together. Friction happened though they didn't know it.
        ?
    Friction is everywhere. Have you ever noticed situations where friction is happening? If not, ask your parents to take you out in a car. If it is not too hot, touch the tires (轮胎) of the car before and after a short drive to see how much warmer they get from friction.

    Yang Nan, 17, was happy to move to her new home in a northern area of Beijing. She was told that her neighborhood used to be rich farmland planted with vegetables, corn and wheat. But looking at the new road, beautiful parks and supermarkets, to her surprise, Yang couldn't see any sign that food was once grown there.
    Yang is not alone. In recent years, many Chinese people have moved into new houses in country areas. Tall buildings have been built everywhere in the suburbs. The crops and fruit trees are no more grown there. But these changes have caused big problems too, warns Gan Zangchun, an official（官员）at the Ministry of Land and Resources(国土资源部）．
    "Chinese cities are growing very fast. This has made the area for farmland much smaller than before. This is really bad for the country's ability to grow food, not to mention the lives of farmers," said Gan last Monday.
    As the population of China is growing all the time, the country needs more farmland to grow food for the increasing people of China. But the recent rise in house prices has made selling land a good business. A lot of land has been used to build new houses for sale. So you can see, the shortage of the farmland is now a very serious problem.
    Pollution, such as, oil pollution, industrial(工业) pollution and water pollution, which makes land useless, is another reason for the big drop in China's farmland. About 2.67 million square kilometers of land in China have been polluted and turned into desert.
    Today, can we use less farmland to grow enough food for more people? Of course not! The government wants China to have at least 120 million hectares（公顷） of farmland. Only in this way can we raise such a big population. But there are only about 121.8 million hectares left. "It will be really difficult to reach the goal", Gan said. He said that the government would fight illegal(非法的) land use and something useful must be done to stop farmland from becoming desert.

It is reported that some developed countries have shipped broken parts of computers to China. Last month Hong Kong officers found 131,000 kilograms of broken computers, TVs and phones sent from Japan.

Things like these are called electronic waste, or e-waste. Dealing with them is not an easy job. Every time an old computer breaks down, it needs to be dealt with safely. What is worse, at present, broken computer parts are usually buried. It may be hundreds of years before they are really g one in the earth.

Many places in China are polluted by e-waste. Guiyu in Guangdong Province is one of them. This town is named as "the e-waste capital of the world". It has to deal with 1.5 million kilograms of e-waste each year, from which it makes 75 million yuan. But it comes at a cost. Many of the poisons in e-waste find their way into the environment. An environmental group has found the air, the earth and the rivers in Guiyu badly polluted.

Luckily, the Chinese government wants to change the situation. This year, China passed a new environmental protection law. Computer companies like Lenovo and Dell will be asked to take back their old computers. Hopefully, the problem with e-waste will be solved in the near future.

Do stars only appear at night? The answer is no .Venus （金星） is the one and only star that can be seen in the daytime. It shone at its brightest in the night sky on February 17^th, 2017.

Venus is the second planet from the sun in our solar system. It is the second brightest natural object, behind Earth's moon, in the night sky. Why is it so bright?

First of all, Venus is the closest planet to Earth. It is also covered by highly reflective （反射的）clouds, which can reflect about 70 percent of the sunlight striking（照射） it, almost twice as much as Earth does.

Some called 2017 the year of Venus, because the planet is at its brightest when it goes further away from the sun, and nearer to Earth. The brightest moment happened once in February, and happened again, during daylight, on April 30^th.

If Venus is so bright and close to us, isn't it a better choice for human exploration than Mars? It is closer to Earth than Mars and it's closer to Earth in size. The closer distance to the sun means solar power would be easier to generate （产生） as well.

However, with a temperature of about 465℃on the surface, Venus is the hottest planet in our solar system!

But scientists never give up. Recently, a team of NASA and Russian scientists created new computer equipment that can stand the temperature of 480℃. It can work under Venus-like conditions for almost 22 days.

The next step, according to the scientists, is to send a probe（探测器）to Venus by 2025.
