There are many ways for us to reduce(减少) waste. For 1, we can reduce paper and plastic bags. We can also recycle newspapers, glass, and cans(易拉罐) to make new things. Here are some useful ways to 2 waste.
     Write on 3 sides of paper
     Many people write on only one side of their paper. Why not stop wasting the other side? Some students only use half the pages of their 4 before getting new ones. Try to use up all the paper. People often give cards on birthdays or festivals. How about trying to 5 e-cards instead?
     Don't throw away your old batteries.
     Maybe you do not know that old batteries make the earth 6. This is because they have poisonous parts in them. So, don't throw away batteries. 7 them together. Try to use rechargeable(充电的) batteries for your games and CD players.
     Give off all your unwanted clothes
     There are many poor families in China. You may ask your mother to 8 your unwanted clothes. Then you can pass them on to those poor children. You will feel 9 that you are helping someone else. Also, you can understand 10 your friends or relatives(亲戚) want them before throwing them away.

Dear human beings,

    Hi! I'm 80 years old now. So I've seen 1 of the world. We've lived on Earth with you thousands of years. Each day we release(释放) O₂ and remove harmful gas so that you have fresh 2; we help prevent the Earth's soil（土壤）from being washed away, and above all, we give all kinds of fruits, nuts, beans as well as 3 to you.

    We are now in great 4 because of you. You are killing us at a terrible speed. You are burning and cutting down millions of us each year, but you're not 5enough. For every tree being planted today, 30 trees are being cut down. What would you do if all of us 6? Perhaps you would die, too.7 us, you wouldn't get enough material for buildings, furniture（家具）, paper products, and your cities would 8ugly. Moreover, air pollution and noise pollution would become more and more serious, and your life would become nasty.

    The 9 thing for you to do now is to stop your bad manner. We are the best fighters 10 pollution and we are your best friends!  

Your friend,

An old tree

How to lower costs and improve the living quality?

There are numerous products posted on social media, and you might believe an electric toothbrush, Luna facial cleaning massager, a flight ticket to. Phuket and so on will bring you a better life. But for many graduates or those who have worked for only one or two years, your income cannot keep pace with（跟上） expense. {#blank#}1{#/blank#}Here are some tips:

Keep running or doing yoga

It seems to be a challenge to afford a fitness center costing over 10,000 yuan in annual fees or for a personal trainer. But you can buy a pair of sneakers or a yoga mat instead. Running in a park regularly or doing yoga at home using free online resources is definitely a type of quality life. {#blank#}2{#/blank#}

Go to museums or libraries

Chasing young good-looking stars, watching their films and buying expensive tickets for their concerts are popular with many young people. {#blank#}3{#/blank#} You seem to fail to take into account（考虑到） a variety of exhibitions and resources updated frequently in major cities. Why not have a try? What you need to do is to choose themes that you are interested in, make an online appointment in advance and then enjoy your weekend.

{#blank#}4{#/blank#}For some young people, the easy access and the discounts of online shopping make it really attractive. Sometimes what you buy online is not what you really need and the demands are created by the producers. For example, many young people buy new clothing that they don't wear. {#blank#}5{#/blank#} Money is not the only thing that can drive your quality of living, but your optimistic attitude towards life and self-disciplined way of life are.

Stanley Karras works as a meteorologist (气象学家) in Tampa, Florida. His job is to follow hurricanes (飓风) by plane and provide information about them for scientists.

What do you like most about your job?

I love the travel most. Running after hurricanes has taken me all over the world. It's exciting to end up in different cities and different countries day after day. If you're a meteorologist, you have to love flying. I also love working with top scientists. I have learnt so much from them and we have had a lot of exciting time together.

Do you make any sacrifices (牺牲) to do this job?

Yes, I'm so far away from my family. They all live in the UK. My wife is with me, of course, but her family is also in the UK. So we're pretty cut off from them all over here.

What would you like to do next?

I'd like to join a space programme and be the first meteorologist in space, but I have not come up with an experiment(实验) to do in space yet. There aren't any hurricanes!

What tips would you give to someone wanting to do your job?

Study maths, science and meteorology well. There are many areas in meteorology to study. I have taken the hurricane hunter path, but you could be a weather reporter or study in other areas.

Anne and Joseph are talking about an interesting question. Why do some people change their names? There can be many reasons. Hanna changed her name to Anne because she thought it would be easier for people to remember. On the other hand , Joseph is thinking about changing his name to an unusual name because he wants to be different. 

People have a lot of reasons for changing their names. Film stars, singers, sportsmen and some famous people often  change their names because they want names that are not ordinary, or that have special sound. They chose the "new names " for themselves instead of the names their parents gave them when they were born. 

Some people have another reason for changing their names. They have moved to a new country and want to use a name that is usual there. For example, Li Kaiming changed his name to Ken Lee when he moved to the United States. He uses the name Ken athis job and at school. But with his family and Chinese friends, he uses Li Kaiming. For some people, using different names makes life easier in their new country. 

In many countries , a woman changes her family name to her husband's after she got married. But today, many women are keeping their own family name and not using their husband's. Sometimes, women use their own names in some situations and their husbands' in other situations. And some use both their own names and their husbands'.
