In England, people often talk about the weather because you can experience four seasons in one day. In the morning the weather is warm just like in spring. An hour 1 black clouds come, and then it rains hard. The weather gets 2 cold. In the late afternoon the sky will be clear, the sun will begin to shine and it will be summer at this time of a day.

    In England, you can also have summer in winter, 3 have winter in summer. So in 4 you can swim sometimes, and in summer sometimes you should wear warm clothes.

    When you go to England, you will see some English people take umbrellas or rain-coats with them on the 5 morning, but you shouldn't laugh at them. If you don't take an umbrella or a raincoat, you will regret later in the day.

    When the weather is hot, you go to a lake or an ocean. When you are near a lake or an Ocean, you feel cool. Why? The sun makes the earth hot, but it cannot make the water very hot. Although the air over the earth becomes hot, the air over the water is still cool. The hot air over the earth goes up. Then the cool air over the water moves in and takes the place of the hot air.

    Then you may ask, "Why is the ocean full of salt?" Scientists will say that the salt comes from the rocks. When the rocks get very hot or very cold, they crack (爆裂). Rain falls into the cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. And then you may doubt, "But the ocean does not get more salty every year. Scientists are not sure about the answer to this question.

    We know a lot about our world. But there are still many answers that we do not have, and we are curious about them.

    The summer holiday is coming. Try to take some time off from school and have fun. Here are some ideas for planning your summer holiday.

    Cars make our lives more convenient. But they can also be a problem. For example, fossil fuel (化石燃料) cars mainly cause air pollution.

    To improve the environment, many countries are developing electric vehicles (EVs,电动车). Among them, China is taking a leading role and has created the world's largest EV market.

    Last year, over 40 per cent of the 753,000 EVs sold in the world were sold in China, more than twice as many as the number sold in the United States.

    "Filling up a fossil fuel car with gas (汽油) is more expensive than charging (充电) an electric car," said Wu Hao, who bought an electric car this year.

    However, there are still some problems. It can be hard to find charging piles (充电桩) and the cars can't go far before being recharged.

    Some of these problems are being solved. In 2014, China had 31,000 charging piles. Now China has the world's largest EV charging network, with more than 450,000 charging piles in total.

    Developing EVs is one of many efforts that China has made to cut down pressure on its environment after the government promised to stop increases in carbon dioxide emissions (二氧化碳排放量) by 2030.

    "As China goes, so will the world's car industry," the Wall Street Journal said.
