It's a wonderful, warm summer day without a coud in the sky. You're outside, and you can feel the sun's heat on your skin. Do you know what else you are feeling? You're feeling the sun's energy! Without it, the earth would be a cold, dark, lifeless place The sun's radiation(辐射) gives us light and heat energy.

 The Sun's radiation can be harmful to us as well. We can't see it, but ultraviolet(紫外线) radiation comes from the sun along with heat and light. You can not see ultraviolet radiation, but it influences our health. Ultraviolet radiation is what burns our skin.

 Ultraviolet radiation has three parts: ultraviolet radiation A, ultraviolet radialion B, and ultraviolet radialion C. Waves of ultraviolet radiation  A and B may cause harm to our body when we get sunburned. The harm to our body can give us skin cancer(皮肤癌) and cause other health problems.

 You can help to protect yourself from ultraviolet radiation by wearing sunscreen(防晒霜), sunglasses and hats.

 Try to stay out of the sun when it is especially strong .You can find out ultraviolet radiation levels by watching the weather report on television.

    Rose was born on February 29th, 2004. By 2010, her parents had 6 birthday parties for her. But most(大多数) of them were on February 28th. One day, she knew that only February 29th was her real (真实的) birthday. It comes every four years, so she didn;t want to have birthday parties on February 28th any more. After that, she had only one party. That was in the year 2012. On that day her grandparents, all her uncles, aunts and cousins came to her home to celebrate her birthday. She got so many presents. She thinks it's much more interesting to have a birthday party every four years.

    ［1］China's “four great new inventions” in modern times have made the daily life of the public more and more convenient. They are the high-speed railway(HSR), shopping online, shared bikes and mobile phone payment.

    ［2］Living in Hong Kong, I knew them from the papers, the TV and the Internet. But last month I had the chance to experience all of them.

    ［3］As usual, the golden week stopped the traffic. It was hard to get a railway ticket anywhere in the train stations. But I bought a train ticket to Beijing on the Internet and paid for it through Zhifubao. It was even cheaper than it was bought in the station. Then we got on the high-speed train. I was shocked at its speed and quietness. There was no noise which the train made while running. It was reported that China has the longest high-speed railway in the world, which is regarded as a “name card” for China.

    ［4］China's HSR has also gone abroad. In 2014, China finished building its first foreign high-speed rail in Turkey. In June 2015, China and Russia agreed to build the 770 km of high-speed railway connecting Moscow and Kazan. In October 2015, China helped Indonesia to build a high-speed rail between Jakarta and Bandung.

    ［5］Did I feel bored during the trip on the train? Not at all. I bought many cheap and good things in Taobao and Tmall on the Internet through my mobile phone. It's amazing that there are oceans of products in Taobao and Tmall.        ［6］Soon we arrived in Beijing. We got on a bus near the train station.     getting off the bus, my friend told me that the bus stop is far from his home. I thought we would have to spend much money going to his home on a taxi, but it seemed that he wasn't worried about that. He showed me some bikes on the side of the street. They are called shared bikes. We only need to use our mobile phones to scan(扫描) the QuickResponse code(二维码) on shared bikes, then we could ride the bikes anywhere we wanted to go. It was so cool!
