    Is there link between humans and climate change or not? This question was first studied in the early 1900s. Since then, many scientists have thought that our actions do make a difference. In 1997, the Kyoto Protocol explained our role in the Earth's changing atmosphere and set international limits for gas emissions(排放) from 2008 to 2012. Some countries have decided to continue these reductions until 2020. More recently, the Paris Agreement, stuck by nearly 200 countries, also aims to limit global warming. But just now how much warmer it will get depends on how deeply countries cut carbon emissions.

    There are many useful suggestions that can help one to improve English. Here are some of them to increase one's English language vocabulary.

    Learning English vocabulary is about much more than just learning the right words. It is based on understanding important words and expressions.

    Learning a word will not help very much if you quickly forget it. Researches show that it takes from 10 to 20 repetitions(重复) to really make a word part of your vocabulary. Since most words are learned from how they are used in context (上下文), the more words one is shown, the better vocabulary one will have. Keep a piece of paper close to you. When you read, pay close attention to the word you do not know, write the word down and try to understand its meaning from the context. Then look up the word in a dictionary. 

    Remember that if you do not use English words that you have just learned in conversation or writing, you will forget them very quickly. So the best way to learn new words effectively is just by trying to use them in conversation and writing. Remember also that practice is the key to fluent spoken English.

    Building vocabulary is a life-long task. Remember: ＂In the beginning was the word.＂ Your future could depend on how rich your vocabulary is. It will also determine the quality of your communication.

    Teachers in some secondary schools in Britain are worried that their job may become impossible shortly unless something can be done to restore discipline in the classrooms. In the problem schools, mostly in large cities, a small minority of teenage pupils disturb lesson to such an extent that the teacher can no longer teach their classes effectively.

    Some people consider that the permissive (随意) nature of modern society is responsible for such kind of behavior. Small children who are continuously encouraged to express themselves without reservation are naturally unwilling to accept school discipline when they grow older. Furthermore, modern teaching techniques) which appear to stress personal enjoyment at the expense of serious study work, might be teaching the child to put his own interests before his duties to the community in which he lives.

    Perhaps the problem can be solved by improving facilities for the moral guidance of these difficult children or by better cooperation between the schools and the parents—for the parents may be mainly responsible for the bad behavior of their youngsters. Violence at home, violence and crime on TV make some children turn violence themselves.

    But some of the teachers believe that there ought to be a return to more “old fashioned” methods. At present, in some school teachers are even not allowed to punish a child who does something bad and wrong. Physical punishment is not permitted now. People are too soft on children these days. It seems that children can do whatever they like at school while the teachers can't do anything to punish them. I don't know why the schools authority abandoned some of the effective punishments that worked well. Things like that didn't happen when we were at school because the teachers kept those problem students under control by using a stick.

    The cost of living in countries like the U.S., Britain, Australia or France has skyrocketed in recent years. However, if you're willing to leave your country and explore life in other areas, there are many countries boasting an extremely cheap and low cost of living. Check out the following countries when planning your next move.

    Ecuador

    Ecuador is similar to the United States in many ways, and as a result has become a popular American getaway. They even use the U.S. Dollar for their currency.

    Mexico

A decent sized home can cost around $139000, which is relatively cheap in relation to homes in the United States.

    Vietnam

    Vietnam has also become a popular tourist destination in recent years. There are many million dollar luxury homes by the beach, but you can find a modest fiat or small home for around $25000 to $50000 if you search in the right areas.

American country music is also known as country western music. It has a very long history. It comes from the folk songs of immigrants (移民) from Britain.

 Country music uses simple music and words to express everyday feelings such as loneliness, love, and sadness. That is to say, country music describes life. It talks about friends and enemies, trucks and roads, farm and crops. People in many parts of the world like country music, because everyone can understand what the music is about.

Country western music became popular first among cowboys (牛仔) in the American west countryside. Cowboys had to take care of cows day and night. When they were alone with the cows, they often sang beautiful and peaceful songs to calm the animals and to overcome their own fear. They were not well-educated and so they sang about their daily life in very simple words. They played guitars, violins and other instruments. In the south of America, many people added instruments from their homes, like bottles and spoons. When cowboys visited their friends and families on holidays like Thanksgiving, they usually sang and played country western music.  

In recent years, many musicians have made country western music a little different from the one in the past. These changes make the songs sound even better. Today singers such as Carth Brooks, Reba McEntire, Emmylou Harris, Lyle Lovett, Eddie Rabbitt, LeAnn Rimes, Randy Travis and a group called Alabama are singing and playing in different styles. They have brought country western music more and more fans from all over the world.

First published on October 15, 1952, "Charlotte's Web" is a popular children's book written by well-known American author E. B. White and {#blank#}1{#/blank#}（illustrate）by Garth Williams that deals with themes of the nature of friendship, loss, fate, acceptance, and renewal. The story centers on a pig named Wilbur and the unlikely but deep friendship {#blank#}2{#/blank#} shares with an uncommonly talented spider named Charlotte.

While it's normal in the course of events on a farm for pigs {#blank#}3{#/blank#}（kill）when they reach a certain size and age, clever Charlotte works out a scheme to keep Wilbur from his fate by weaving words into her web to create what amounts to a one-pig publicity campaign. By promoting Wilbur to celebrity status, Charlotte ultimately saves him {#blank#}4{#/blank#} his date with the butcher's knife.

The ending of the "Charlotte's Web" is bittersweet, however, {#blank#}5{#/blank#} while Wilbur survives, Charlotte does not. But even Charlotte's passing is a lesson-for Wilbur and those reading his story-about the nature of death and renewal.

Death and destiny are both themes that the book explores. While Charlotte is willing to help Wilbur avoid a destiny that's being imposed on him by outside forces beyond his control, she also understands that some fates are inevitable: All living creatures are born, {#blank#}6{#/blank#}（have）a life cycle, and die. Charlotte accepts her role in this natural circle without regret.

Charlotte helps Wilbur realize that immortality is not about living forever, but rather, {#blank#}7{#/blank#}（ensure）that new generations will follow. She also helps him understand that love and friendship are not fixed in quantity. While we may lose a friend, new friendships can come along, not as replacements for {#blank#}8{#/blank#} we've lost, but as blessings to build on what we've learned.

"Charlotte's Web" got its inspiration from true experiences that author E. B. White had on his farm in Maine, {#blank#}9{#/blank#} he penned the book and lived until his death in 1985．While the author claims that the book {#blank#}10{#/blank#} never be considered a moral tale, certain messages related to moral principles, or rights and wrongs, are obviously established in "Charlotte's Web".
