The preventive measures for forest fires include some pre-emptive(抢先的)methods that can help re?duce the risks of fires and control their severity and spread,and thus, maintain ecological balance and pro?tect resources. Close monitoring of forest fires caused by natural factors can help prevent their spread to a large extent. To contain forest fires, fire departments usually use water and chemical fire retardants(抑制剂)that can be dropped from planes and helicopters. To control the spread of wildfire, firefighters usually create a control line by removing all fuel from an area so that the fire cannot travel across it.

Controlled burns are often employed by government authorities to reduce fuel build-up,and clean up the fall?en leaves,and thus,prevent the spread of forest fires to a vast area. Regular controlled burns can also help main?tain biodiversity(生物多样性),as the smoke and heat produced in the process can facilitate (促进)the growth of seeds of certain plant species. Apart from these, re?sponsible human behaviour can help reduce the number of forest fires to a great extent. In fact, we can reduce the number of wildfire dramatically by not leaving be?hind any source of fire in the forest.

Forest fires can affect climate and weather to a great extent, besides causing severe damage to valuable trees. Wildfire can increase the level of greenhouse gases (water vapour, carbon dioxide, etc. ) , and therefore in?crease pollution and global warming. However, they are also an important part of the ecosystem,and many plants depend on the heat and smoke generated by wildfire for their growth and reproduction. But large wildfire can cause extensive damage to the ecosystem, which again highlights the importance of effective control and pre?vention of forest fires.

China's new term, Tuhao, may be in next year's Oxford English Dictionary. The word caught the at?tention of the dictionary's editing team after BBC's re?cent programme on influential Chinese words. "If its in?fluence continues, it is very likely to appear on our up?dated list of words," said Julie Kleeman, project manag?er with the editing team.

In Chinese "tu" means uncouth(笨拙的)and "hao" means rich. It has traditionally been referred to rich people who throw their weight around inChina's coun?tryside. The word became more popular in September with the launch of Apple's new gold-coloured iPhone, which is loved byChina's rich people. The colour be?came known as "Tuhao gold". The word is now also used by the online community to refer to people who have the cash but lack the class to go with it. Kleeman also mentioned two other Chinese words―Dama and Hukou―which may also make it into the dictionary.

People can have an intuitive(直观的)grasp of the meanings if they see pinyin, Kleeman said, adding that people avoid using an English word to keep the original meaning.

"We have nearly 120 Chinese-linked words now in Oxford English Dictionary," she said. Some of them are guanxi, which means connection and taikonaut, a mix of taikong, meaning outer space, and astronaut.

The new words will be first uploaded on the official website before the dictionaries arrive. The online ver?sion is also renewed every three months. "It at least broke our old rules. It used to take 10 years to include a new word but now we keep the pace with the time," ac?cording to a statement from ex-chief-editor John Simpson.
