Tara and Beth met in a dancing class and became close friends very quickly. Soon Beth felt comfortable talking to Tara about her own problems, and Tara was always happy to listen to her. One day, Beth heard some other girls talking about the things that only she and Tara knew. Later, Beth found out that Tara was talking behind her back. Beth didn't understand how Tara could be so nice when she was with her, but be a different person when they were not together. The next day at school, Beth started saying bad words about Tara. From then on, when they met, they both said bad words about each other.

    It was clear that Tara was not a very good friend to Beth when she talked behind Beth's back. Why did Tara start doing this? Was she not a nice person? Maybe not. There might be something else going on.

    At last, Beth found out that Tara's problem came from jealousy(嫉妒), because Tara didn't have nice clothes or expensive things like Beth's.

    195 countries reached an agreement(协议) on Dec. 12, 2015 after two weeks' talks in Paris. They talked about climate(气候) change. It is the first time in history that most of the world's countries, rich or poor, promised to take action to deal with climate problems.

    Below is a chart showing where the greenhouse gas(温室气体) comes from.

Where is greenhouse gas from?

    The Paris Agreement(巴黎协定) sets up a goal of cutting down the earth temperature to less than 2℃. If the warming gets above 2℃， there will be serious problems on the earth like natural disasters.

The agreement also asks countries to volunteer to do things. For developed countries, they will do even more. They have a plan to offer over 100 billion dollars to help poorer countries to develop clean energy like water and wind power.

    However, the Paris Agreement won't solve earth warming by itself. The future also depends on how well each country will carry out their promises.

    There is half a glass of water on the table. Is the glass half empty or half full? This question can represent a situation where there is both opportunity(机会) and trouble, but people with different point of views see the same situation in different ways. Ask yourself this question and see what kind of person you are.

    If your answer is "half empty", it shows that you tend to look on the dark side of things. You are a negative-thinking person. You are worried about what you don't have or what you have lost more than what you already or still have. In other words, you are a pessimist(悲观主义者).

    If you see the glass as half full, you tend to look on the bright side of things. You are a positive-thinking person. You know you should take the opportunity that comes your way rather than worry about getting into trouble. This is to say, you are an optimist.

    We don't live in a perfect world, but if we can change the way we see things, the things we see will change.

    Last year, I did not like my English class. ⑴Every class was like a bad dream. The teacher spoke so quickly that I did not understand her most of the time. ⑵I was afraid to ask questions, because my pronunciation was poor. I just hid behind my textbook and never said anything.

    Then one day I watched an English movie called Toy Story. ⑶我爱上了这部激动人心又有趣的电影。So I began to watch other English movies. I discovered that listening to interesting conversations is the secret to language learning. I also learned useful sentences like "It's a piece of cake" and "It serves you right". ⑷I didn't understand these sentences at first. Then I looked them up in a dictionary. ⑸现在我非常喜欢我的英语课。

Are you nervous when you stand in front of the public? Are you afraid to make a speech?

Li Jun, a middle school boy felt shy when he was making a speech the other day. Before that, Li had thought it would be quite easy to speak in front of 1 classmates. 

"I was wrong. It was very different and much 2 than talking to my classmates during playtime," Li said. "I tried, but it was really difficult to speak. I felt like a mute (哑巴) and wanted to leave the classroom 3 ."

Li is not alone. Many middle school students now have the same 4 : they can talk about their ideas freely 5 their best friends after class, but can't speak in public. According to Zhou Hong, a teacher from a university, the main reason is that schools in China pay more attention to writing instead of 6 . 

Zhou hopes schools can give students more chances to open their 7 , such as speech competitions, English corners and class discussions. Students can join in any one they want. 8 he also gives some advice to students. "During your free time you should 9 more. When you're speaking in public, take it easy. Just imagine you're talking to nobody and speak up your ideas clearly," Zhou said. "That 10 a fine public speech and you'll feel confident."

When you look at me now, you won't believe that I once weighed over 300 pounds. Yes, I used to be a really 1 girl. I never worried about it until I had a medical examination one day. 

The doctor told me that I was having heart trouble. He said it would be 2 if I could lose some weight. Then I decided to make a 3 .

After a year and five months, I lost 104 pounds. I didn't have any expensive food, medical treatment or camp- style exercise. So what was the secret to my 4 ?

First, I looked through the Internet for some 5 on losing weight. Of course, I saw many advertisements(广告), but I bought nothing. The only thing I did was change my bad6 . I stopped having drinks with too much sugar and 7 my love for sweet cakes. Now I have got used to eating a lot of green vegetables and using vegetable oil only. I 8 eat after 6:30 p. m. because it's unhealthy to have a late dinner. Also, I 9 for 15 to 20 minutes five days a week to keep fit. 

People sometimes say, " You don't need to tell me what to do. I've known it already!" The fact is that knowing what to do and doing what you know are completely 10 . The important thing is to know what to do and then keep doing it.
