    Believe it or not, many of the biggest change in how English is spoken have come from common people in the streets. And one of the most important places which English has changed is the playground! These playgrounds can be any place where the young people meet, such like a sports field or a beach. Often words using by black kids in big cities become popular for other kids many years later. On the beaches of southern California, teenagers invented words to describe what they felt when they surfed. These words found its way into the high schools and then to other places. Similar changes happen among young people in Ireland and Australia. Children from one group would find ways to play with another group more easily. Often they made new words just develop an identity different from their parents.

Dear Mandy，

    I'm not doing well in my lessons at school, especial in maths. My dad says I must try hard because he wants me go to university. He thinks I'm lazy，but it's not true. I work really hard,often study late into the night! I've tried to talk to my mother，but she always said I have to work as hard like my brother does. My brother doesn't study very hard，and he always gets excellent grades. It's not fair! The only thing I like it is art. My teacher says I'm the best student she's had for year. When I told my dad，all he said was，“ You mustn 't waste your time in art. You must focus your mind on your lessons! ”I'm feeling quite puzzling as to what to do now. Would you please help me out?

    Thanks a lot!

Yours sincerely，

Lisa

    I am writing to ask for whether you are able to do me a favor. I want to have a pen pal, hopefully a girl in the early twenties, and with interests similarly to mine. In my mind, he is someone interesting in traveling, swimming, and playing table tennis. Beside, it will be better for her to have a pet dog as I have been keeping one at home for some time. With such pen pal, I hope I can share with her my experiences in traveling, taking care of pets, or whichever we have in common. I believed I will improve my English by doing so and learning more about her country. I am looking forward to hearing from you soon.

    Nowadays, it is very easy to find a student who are nearsighted. What's worse, the number of nearsighted students is still increased. From my point of view, there are many reasons why can cause nearsightedness. First and the foremost, wrong postures will easily result in nearsightedness. Reading on the dark places can lead to nearsightedness too. Moreover, too much reading without a rest can another important reason. My dear friends, it is highly time that we should pay attention to protecting your eyes. The most useful methods is to do eye exercises more often and relax for a while after reading. Watch green trees can also do good to the eyes.

    China and Western country may have different cultural beliefs about certain animals. But when it comes to pigs, we somehow reach an agreement that pigs are lazy, ugly, stupidly and shameless. Neither of these words describing pigs are exactly positive. Moreover, the truth is what pigs have some good qualities. And there's probably no good time to clear their names than now, with the arrival of the Year of the Pig on Chinese Spring Festival, which fell February 5 this year. According to a paper publishing in 2017, pigs can tell between those who treat them well or those who don't. Perhaps these are the qualities of pigs to keep it in mind—their intelligence, cuteness and patience.
