Since the powerful (猛烈的) earthquake took place in Sichuan, more than 200 thousand volunteers across China have been helping there! They do all kinds of work or come up with ways to help improve life. Some offer their professional skills for free. Others have no qualifications (资历), but they love to work hard to help.

Now more and more teenagers actively look for volunteering opportunities, too. They volunteer because they think it will be fun or they will learn something. They also like the idea of being helpful to others, even if it is just handing out books for the teacher. As they get older, these reasons are still the same, but there are other important reasons for volunteering such as learning on-the-job, getting work experience, and improving their social life.
All volunteers bring joy to the people they help in so many ways. They might read books to the blind, fix up broken homes, find ways to get water for villages. Could you be a volunteer? What kind of volunteer work could you do? There is someone in the world who needs you.

B. Volunteers offer their help without any pay.
C. Young kids can’t be volunteers.

Body language is the quiet，secret and most powerful language of all! It is said that our body movements communicate about 50％of what we really mean while words themselves only do 7％.So while your mouth is closed，just what is your body saying……
Arms: How you hold your arms shows how open and receptive you are to people you meet．If you keep your arms to the sides of your body or behind your back, this suggests you are not afraid of asking on whatever comes your way. Outgoing people usually use their arms with big movements while quieter people keep them close to their bodies. If someone makes you angry, just cross your arms to show you’re unhappy!
Head: when you want to show your confidence，keep your head level. If you are monitor in class, you can also take on this position when you want your words to be taken seriously. However, to be friendly in listening or speaking, you must move your head a little to one side.
Legs: Your legs will move around a lot more than normal when you are nervous or telling lies．If you are at interviews, try to keep them still.
Mouth: When you are thinking，you often purse your lips．You might also use this position to hold back angry words you don’t wish to say．However, it will probably still be noticed, and people will know you’re not pleased.

书面表达参考范文
At the class meeting our teacher read us a piece of news in the newspaper that a certain student in a middle school smoked and he wouldn’t get rid of the bad habit though his teacher and classmates warned him not to smoke any more. He even stole money to buy cigarettes and was put into prison in the end. This really gave us a shock.
Now some middle school students smoke because they think smoking is enjoyment.
In fact, smoking does harm to health especially to the teenagers. Doctors and scientists have found that smoking may cause serious illness, such as heart trouble or cancer. More and more people in the world have given up or have decided to get rid of smoking. We teenagers should stop doing such silly things, too.
As the future builders of our country, we students should make full use of time to study, and do things to benefit our homeland, our people and ourselves. From now on smokers should make up their minds to break away from the bad habit and form good ones.

第一部分走进化学世界 变化和性质 一、物理变化和化学变化 1. 物理变化：没有新物质生成的变化。 （1）宏观上没有新物质生成，微观上没有新分子生成。 （2）常指物质状态的变化、形状的改变、位置的移动等。 例如：水的三态变化、汽油挥发、干冰的升华、木材做成桌椅、玻璃碎了等等。 2. 化学变化：有新物质生成的变化，也叫化学反应。 （1）宏观上有新物质生成，微观上有新分子生成。 （2）化学变化常常伴随一些反应现象，例如：发光、发热、产生气体、改变颜色、生成沉淀等。有时可通过反应现象来判断是否发生了化学变化或者产物是什么物质。 化学变化中一定伴随着物理变化。 二、物理性质和化学性质 1. 物理性质：物质不需要发生化学变化就能表现出来的性质。 （1）物理性质也并不是只有物质发生物理变化时才表现出来的性质；例如：木材具有密度的性质，并不要求其改变形状时才表现出来。 （2）由感官感知的物理性质主要有：颜色、状态、气味等。 （3）需要借助仪器测定的物理性质有：熔点、沸点、密度、硬度、溶解性、导电性等。2. 化学性质：物质只有在化学变化中才能表现出来的性质。 例如：物质的可燃性、毒性、氧化性、还原性、酸碱性、热稳定性等。 仪器使用和操作 一、药品的取用原则 1. 使用药品要做到“三不”：不能用手直接接触药品，不能把鼻孔凑到容器口去闻药品的气味，不得尝任何药品的味道。 2. 取用药品注意节约：取用药品应严格按实验室规定的用量。如果没有说明用量，一般取最少量，即液体取1-2mL，固体只要盖满试管底部。 3. 用剩的药品要做到“三不”：即不能放回原瓶，不要随意丢弃，不能拿出实验室，要放到指定的容器里。 4. 实验时若眼睛里溅进了药液，要立即用水冲洗。 二、固体药品的取用 1. 块状或密度较大的固体颗粒一般用镊子夹取。 2. 粉末状或小颗粒状的药品用药匙（或纸槽）。 3. 使用过的镊子或钥匙应立即用干净的纸擦干净。 三、液体药品（存放在细口瓶）的取用 1. 少量液体药品的取用——用胶头滴管滴加药品应悬空垂直在仪器的正上方，将液体药品滴入接收药液的仪器中，不要让吸有药液的滴管接触仪器壁；不要将滴管平放在实验台或其他地方，以免沾污滴管；不能用未清洗的滴管再吸别的试剂（滴瓶上的滴管不能交叉使用，也不需冲洗） 2. 从细口瓶里取用试液时，应把瓶塞拿下，倒放在桌上；倾倒液体时，应使标签向着手心，瓶口紧靠试管口或仪器口，防止残留在瓶口的药液流下来腐蚀标签。 3. 量筒的使用 （1）取用一定体积的液体药品可用量筒量取。读数时量筒必须放平稳，视线与量筒内液体

Module 1 Unit One The flight was late. Lingling: Welcome back, everyone! Betty: Hi Lingling! How was your holiday? Lingling: Not bad! I went to Henan Province. But the trip back was very long. The train was full of people, and I had to stand for over six hours. Betty: Bad luck. Where's Tony? Daming: He's staying with his family in the UK, and flying back tomorrow. The flights were late today. Betty: Why is travel so difficult in winter? Lingling: Well, it's the busiest season in China because of Spring Festival. Where did you go, Daming? Daming: We flew to Hong Kong—and the flight was late! But we took the boat to Landau Island and went to Disneyland. Lingling: How about you, Betty? Betty: We had quite a good time in Beijing. We went sightseeing by bus and by taxi. And last weekend, we took a tour by coach to the Summer Palace and went for a long walk. Daming: And now, better get back to work ... We've got exams at the end of the term. Betty: Yes, but there are plenty of fun things to do this term ... the school trip ... Lingling: ... and the school leavers' party ... Daming: ... the visit to the English-speaking theatre in Beijing ... Lingling: And our trip to Los Angeles! We'll have a great time! Unit Two Excuse Me. You're Sitting in My Seat! The train to Beijing! Lin often dreamed about the train, and about going to the capital. Now it was in front of him, to set off soon. He looked at his brother. "Don't forget where you come from, little brother," Jin said. "And watch your bags carefully." Lin nodded, unable to speak. This was his first long trip by train at the start of his new life, leaving his village and his home for the last 16 years. He held Jin in his arms. With tears in his eyes, Jin pushed Lin away. "Go, brother. Write to us as soon as you get there, OK?" Lin jumped onto the train. There were people and bags everywhere. He pushed past them towards his seat. A young man was sitting in Lin's seat. He was wearing jeans and a very smart jacket, and was smoking a cigarette. What should he do? Six pairs of eyes looked at Lin, while the man looked out of the window. "Sir, you're sitting in my seat," Lin said, with a nervous smile. The other people watched with interest. The man didn't turn to look at Lin, but just looked out of the window. "Excuse me. I have a ticket with the number of the seat you're sitting in!" Lin said in a stronger voice. "I also have a ticket with that number—though it is in another car. Besides, I was here first," said the man, without moving his head. Though he was sitting, he looked very tall and strong. Lin looked at the other passengers for help. "But ... " he started to say. "But what?" The man turned and looked at Lin. "I'm not moving." Finally a man wearing glasses spoke in a loud voice. "This young man has the right ticket for that seat. You should move." Lin felt brave. "See? Please move. I've got a long way to go." "How long?" the young man asked. "To the last stop, Beijing." "I'm getting off before you. Then you can have my seat. "
