I can't remember when I started collecting litter. But it was when I got tired of 1 litter nearby that I realized no one else was going to pick it up.

    I live near a forest in Ohio, America. I can walk there  2 three minutes. I used to love going there to play with my dog. But one day there was 3 much litter there that I became very unhappy. I decided to clean up the forest, and I wanted to 4 happy when I went again. I made my first trip to clean the forest that afternoon. I took a big black rubbish bag with me. Ten minutes 5  I started to pick up litter, my bag was full! There were cans, bottles, broken glass and newspapers in it.

    From then on, I 6  to the forest four times a year to pick up litter. I often stay there for three hours. It makes me feel 7 to do something for the environment. After each trip, I look through all the litter that I've collected. If 8  of it is recyclable（可回收利用的）, I'll keep it. I can't understand why people drop litter. But I will keep on picking it up  9they stop dropping it. I know I am only doing a small bit  10 the earth, but I still think it is important.

    Can you imagine astronauts' everyday life in space? They also need to eat, 1, exercise and relax. They do the same things as us, but they do 2differently.

    On Earth, we put food on a plate and water in a glass. Gravity（重力）holds the food down and keep the water in the glass.3 there is almost no gravity in space, so food can float（漂浮） away，and astronauts must eat and drink 4.

    Sleeping is very different in space. Some astronauts like to float in the air, but most like to be in a 5bag. They tie（捆绑） the bag to a wall 6they won't float away at night.

    Exercise is very important in space. On Earth, your legs 7 your body, but in space, astronauts float. So they do not use their legs often. This is very 8their legs, they must exercise for thirty minutes every day.

    After a day's work, astronauts relax. They may listen to music, read, watch films, play games, or talk to their friends and families 9 the radio. Sometimes they just enjoy 10in the air.

(Now more and more people like shopping online, but is it good or bad? Here're a few different ideas. Let's take a look at them. )

Fred: I spend time on the Internet and buy many things online. I don't need to go out and wait for a long time. Also, I can always get the best things online. 

Dennis: I like shopping online a lot. I love to buy things on the Internet because people can send the products to me in a few days after I click the mouse on what I want. 

Anthea: Shopping online is a good way for us young people. We can save lots of time. When we buy anything online, we can compare different prices and features at the same time. 

Elihu: l like spending time going here and there in different shops and meeting different people, so I do very little online shopping. 

Harriet: 1 especially like shopping online, because it's much easier to choose my favourite things. Now I also have an online store called Millen to sell clothes.

What do you think is an important social skill? I think it's being polite. It can help you make friends, show respect and achieve success. Here are some tips to help you be polite. 

Greet people politely. You can be polite by offering a proper greeting. When first meeting or greeting someone, give him a warm smile. It shows that you are in good spirits and are happy to see him. Also, shake hands to show respect. 

Make small talks. Instead of jumping right into business. You can make small talks first. Talk about their lunch or their day. Listen carefully and pay attention to what they are saying to you. Show them you're interested by asking questions. 

Congratulate other people on their success. When others do well, offer them your praise. If you meet a friend who has recently graduated, won a match, or got a new job, congratulate him. 

Avoid uncomfortable topics. Some topics can make people uncomfortable. You might hurt other people's feelings if you talk about them. Try to keep your conversation in the pleasant areas. 

Make eye contact (接触). When in conversation with someone, look them in the eye when you're speaking. Keeping eye contact shows that you are paying attention. However, don't stare at people all the time. 

China is trying to get an international certification(认证) for Pao Cai. It's a vegetable dish from Sichuan. But some other countries have different ideas about it.

The disagreement(分歧) is between Chinese and South Korean Internet users. Kimchi is a usual Korean food made of cabbage, just like Chinese Pao Cai. Chinese and Koreans both think the vegetable dish comes from their own country.

China recently got a certification from the International Organization for Standardization (ISO) for Pao Cai. South Koreans quickly disagreed, especially on the Internet.

"It's really wrong, Kimchi is a part of our culture," a South Korean Internet user wrote on Naver.com. "I read a story that China now says Kimchi is theirs, and that they are making an international standard(标准) for it. I'm worried that they might take away Hanbok and other cultural symbols, not just Kimchi," said Kim Seol-ha, a 28-year-old in Seoul.

On China's Weibo, Chinese Internet users were describing Kimchi as one kind of Chinese Pao Cai. "Even the name of Kimchi came from Chinese, what else is there to say," one wrote on Weibo.

South Korea's agriculture ministry(农业部) on Sunday said that the ISO's standard is different from that to make Kimchi. "It is not right to report that Pao Cai wins the ISO without differentiating Kimchi from Pao Cai of Sichuan," it said.
