     Nowadays everybody seems to think that they know English. Many people speak it but few speak it really

well. Practice is necessary in speaking English well.

     Reading is also one of the things that will help you to speak English better. Read whenever you can and

whatever you like! Read papers and Internet sites that you like in English every day. Then, you will see that the

number of known words is increasing and you are able to speak with more skills. Then you will have made the

foundations (基础) and a good basis of English. It is not good to stop and get stuck there.

     Going to England or an English-speaking country is a good choice, but many people cannot afford it. If

you cannot go, reading and speaking with your friends will also help you to practice your English. However, I

think it is very good to visit some English - speaking country to see and test your knowledge in everyday life.

You will understand the everyday usage of the language in its natural environment. There your level of English

is going to improve even faster. You ability to speak English is better. Nothing can match the excitement and

happiness when a native speaker tells you that your English is very good!

      Finally, in order to speak English well, you must be persistent (坚持的) and do it every day. It is like

playing the piano. Pianists play it every day and so should you. Include English in your life and you will see

where it is going. Practice, practice! Read, write and improve your language skills and you are on you way

when you will be able to speak it with more and more confidence!

某化工厂的原料、中间产品有火灾、爆炸、中毒的危险性，生产的最终产品有Cl₂和化学名CP的其他产品。生产工艺单元有：原料库房、氯气库房、产品CP库房、生产一车间和生产二车间，厂区周围有居民住宅和其他工厂。为此，工厂需编制事故应急预案。厂长甲将事故应急预案的编制工作交给了厂调度室主任丙。主任丙为了不影响自己和他人的工作，自己用业余时间独立完成。经过近三个月的努力，事故应急预案编制完成，并交给厂长甲。

厂长甲认真审查了厂事故应急预案，认为： (1)事故应急预案中的“一旦事故发生，全厂员工应优先保护重要生产设备，救助他人”的应急原则，体现了保护企业财产，爱厂如家的奉献精神； (2)“应急救援领导小组组长为主管生产安全的副厂长乙”，体现了谁主管谁负责的原则； (3)“当发生重大氯气泄漏时由场外消防部门向周围居民发出警报”，体现了生产不扰民的原则： (4)“启动事故应急预案后，厂长甲应立即向当地安全生产监管部门、环境保护部门报警的报警程序”待分析； (5)应急救援物资和设备的评估合理。因此，厂长甲当场就让主任丙立即将事故应急预案打印发布。

厂长甲决定进行应急演习，并再次将任务交给主任丙。主任丙将演习地点设在氯气库房，厂应急救援指挥部设在氯气库房下风侧的平地上。演习过程为：第一步，指示人员A打开氯气库房中一个装有Cl₂的钢瓶，使Cl₂缓慢泄漏；第二步，工人B、C在氯气库房外侧假装因Cl₂中毒而晕倒；第三步，工人D、E发现有人晕倒立即离开危险区，并向调度室报警；第四步，事故应急预案立即启动，所有应急人员到达指定位置和岗位；第五步，向110、119、120等外部应急救援部门报警；第六步，外部应急救援力量赶到现场，实施人员救护和抢险。
