XI. Read the text and answer the questions.

We know that paper is made from trees, so recycling paper helps to save trees. Saving trees helps to prevent air pollution, soil erosion and floods.

In Britain, 12.5 million tons of paper are used every year. An average person uses 38kg of paper each year. It takes 24 trees to make one ton of paper. 67 % of paper used in Britain is kept for recycling.

Paper recycling is so important and we should recycle our waste paper. To get the benefits of recycling, we must give our contribution to the work.

Paper recycling is also a great chore for children depending on their age. It is an important way for children to learn about responsibility for saving money and trees, and working together. Recycling chores help children to learn about going green and protecting natural resources. Children can also help with recycling at home, at school and in the community.

My favourite subject in high school is English. I not only want to become fluent in foreign language but also desire to deeply understand the beauty of this language. In my opinion, English is one of the most powerful tools that exists nowadays to communicate to other people. It makes easier to make friends around the world. By using english, we can explore the world in a deeper way.

Thanks to this language, I can understand more about different cultures. I am the kind of person who love traveling. Therefore, it’s essential to master in English if you want to communicate to the local people.In addition, you won’t feel lost in the middle of a city because you can ask the natives for help. It was such an amazing method of communication when I travelled in Japan, French or Korea without knowing the local languages.

Furthermore, I believe that English helps a lot to get access to the latest information about scientific topics such as Economics, which by the way was my major at university. If you want to be at the forefront in your professional field, nothing is better than reading the different arles. Whilst, most of them are written in English.

In conclusion, I think that there are many reasons to learn English because of it’s benefits. If you really fall in love with English, you will never want to give up it for any reasons.
