If you did, you must know a person who changed mens swimming history of China and set a new world record for us. Yes, thats Sun Yang who gave us lots of surprise by winning two Olympic gold medals in swimming.Sun Yang became the first Chinese male swimmer to earn a gold medal as he won the 400m freestyle with an Olympic record in London on July 28th, 2012.It is the first gold medal that a Chinese swimmer has ever won in the Olympic history. All of the Chinese are proud of him. He is the hero of the whole China.Sun Yang was born on December 1st, 1991 in Zhejiang. He is 198cm tall and 89kg in weight. Sun Yangs hobbies are singing and reading. Sun Yang loved sports when he was very young. He kept training hard every day and that is why he has made such great achievements.Now nearly every Chinese knows him. When he goes anywhere, he must be followed by his fans, which makes his life less convenient and difficult, but he is very rich. So do you want to be a person like him? 16.

Do you know that HEAT is a form of ENERGY? Yep, this form of energy acts on everything. And, were going to look at a few experiments to learn how this form of energy acts and why we need to know all about it.The heat energy of something is decided by how active its atoms(原子)and molecules(分子)are. A hot object is one whose atoms and molecules are excited and show rapid movement. A cooler objects molecules and atoms will be less excited and show less movement. When these guys are in the excited state, they take up a lot of space because theyre moving around so fast. When the atoms and molecules settle down, or cool down, they take up less space.If a HOT high-energy atom comes into contact with a cool low-energy atom, the excited atom will loose some of its energy to the cool atom. The two atoms will reach an energy level thats between where they each started out. That level is called Thermal Equilibrium. Experiment: If you have a cup of really hot chocolate and want to cool it down, you may put an ice cube in the cup. After the ice has completely melted (disappeared), the hot chocolate and the melted ice have come to Thermal Equilibrium.Now that you have an idea of what heat is, lets look at some of the effects of this form of energy. Heres another experiment. Blow up a balloon, but not all the way. Put the balloon in a refrigerator for about an hour, then take it out. Did it become smaller? Why? It became smaller because the air molecules inside the balloon slowed down and are taking up less space. Now put the balloon in d
