A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover，these areas would reflect more heat into the atmosphere, warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns，potentially causing certain natural disasters all over the world.

    In the past hundred years，humans have begun destroying rainforests in search of three major resources（资源）: land for crops，wood for paper and other products，land for raising farm animals. This action affects the environment as a whole. For example，a lot of carbon dioxide（二氧化碳）in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.

    There are two main reasons for this. Firstly，when people cut down trees，generally they can only use the land for a year or two. Secondly，cutting large sections of rainforests may provide a good supply of wood right now，but in the long run it actually reduces the world's wood supply.

    Rainforests are often called the world's drug store. More than 25％ of the medicines we use today come from plants in rainforests. However，fewer than 1％of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world's shrinking (萎缩的) rainforests.

    Last Friday, after doing all the family shopping in town I wanted a rest before catching the train, so I bought a newspaper and some chocolate and went into the station coffee shop. It was a cheap self-service place with long table to keep a place and went to get a cup of coffee.

    When I came back with the coffee, there was someone in the next seat. It was one of those wild-looking boys, with dark glasses and old clothes, and his hair was colored bright red at the front. What did surprise me was that he'd started to eat my chocolate.

    I was rather uneasy about him, but I didn't want to make more trouble. I just looked down at the front page of the newspaper, tasted my coffee and took a bit of chocolate. The boy looked at me closely. Then he took a second piece of chocolate. I could hardly believe it. Still I didn't say anything to him. When he took a third piece, I felt angrier. I thought, well, I shall have the last piece. “And I got it.”

    The boy gave me a strange look, and then stood up. As he left he shouted out, “There is something wrong with the woman,” Everybody looked at me, but it was worse then I finished my coffee and got ready to leave. My face turned red when I knew I'd made a mistake. I wasn't my chocolate that I had eaten. There was mine, just under my newspaper.

    My friend Susan has a huge-hearted husband. He is once again on the front lines of fighting the fires in Northern CA. As a Chief Battalion leader, his job is very dangerous and his time away from his family is often for weeks at a time during "fire season".

Every time before he leaves, Ethan, Susan and each of the three teens hold one another and thoughtfully each shares the best of their traditions — each promises to do the tasks that will keep the family a well-oiled machine while Ethan is away.

    Ethan has brought back animals that lost their homes in the fires. By now, a gray rabbit, two parrots and a small group of Nubian goats have been added into the family.

    When Ethan is on duty, Susan keeps checking her cell phone for Ethan's text messages. His substantial (大量的) white facial hair is often mistaken for that of Father Christmas by children who are carried out of their burning homes by him.

    For each rescued child, a toy bear is waiting to be matched with him/her. For each adult, Ethan provides clean clothes. He finds pleasure in doing his job well. He is grateful to be often on the front line with frightened people and their poor pets.

    I am mentioning Ethan because by now the big fire has been spreading widely for a week. It has caused 55 deaths and left 500,000 people homeless. Now I am here at my school site, and the smoky air is keeping our students inside, waiting for rescue.

    I grew up in Bensonhurst, Brooklyn. When the holiday decorations went up, there were houses on my block with trees lit up for Christmas in front yards and behind living room windows. I was born in a Jewish family. Even though I received eight presents for Hanukkah (an eight-day Jewish holiday in November or December), it just wasn't fair. My friends had beautiful trees with lights and presents brought by a man in a red suit. I didn't have a tree, and I lived in an apartment building, so I had no chimney(烟囱).

    That year, some neighbors bought a Christmas tree, but it was too tall for their living rooms. They cut off the top and, knowing I wanted to celebrate Christmas, gave the top to my family. After my parents fell asleep, I opened a window in our apartment. I imagined Santa could park his sleigh(雪橇) on our fire escape. When I woke up the next morning, the window was closed and Santa had delivered a present. I can't even remember what it was, but my memory of the morning lasts.

    My relationship with Santa took a break until my daughter, Amanda, was born in 1992. My wife and I saw no reason to deprive(剥夺) her of meeting Santa. In 1998, a friend of mine portrayed(扮演) Santa at the South Street Seaport in Manhattan. He told me to stop by with my wife and daughter, and asked for their names in advance so he could greet them. When he saw us at the seaport, he greeted us by our names. My daughter's mouth opened wide and she pulled back. Maybe she was too young to appreciate this. But other families waiting to see him seemed delighted by his appearance and the gifts he brought.

    My two children are now grown up and do not visit Santa, and we do not have a Christmas tree, yet our family still enjoys the holiday. On Christmas Eve, in the spirit of the night, we leave a plate of my favorite cookies on the kitchen table in hopes Santa will leave a present.

    A popular TV host has reportedly invested about US ＄740,000 in a project to research, preserve and promote the Hunan provincial dialect (方言). Chinese TV presenters are required to speak Mandarin, or Putonghua, as part of their work, but should dialects be allowed on air?

    Bcnu (China): TV and radio stations have the right to decide whether dialects or Mandarin will be used in their programs. The popularity of some dialects in some areas will not challenge the leading role of Mandarin in the whole country.

    Rick N (US): TV and radio broadcasters should take the lead in popularizing Mandarin. To require hosts to speak standard Mandarin is not to oppress (压制) dialects, but it only aims to restrict irresponsible use of language. I think it is unprofessional for some hosts particularly to imitate the pronunciation of dialects.

    Cooper (UK): Dialects are an important part of local culture and now many kids even don't know how to speak their dialects because of the main use of Mandarin around them. It would be a pity if future generations were unable to understand the local dialects. It would be a terrible break in cultural traditions.

    Steve (France): To attract viewers or make more money, some hosts casually use dialects. Demanding TV and radio programs use Mandarin is a move to limit strange and irresponsible use of language, whether it is Mandarin or other dialects. In this way, the decision is also a form of protection for dialects. Hearing standard Mandarin on TV and radio programs is also a basic right of audiences around the country.
