How to learn English well

Ladies and Gentlemen! Good afternoon! My name is Li Xin. I am from Wuming

Experimental School. My topic is: How to learn English well.

Many people like English. As the days go on, it is very important for us to learn

English well. In fact, it is not very difficult for us to learn English well. If you do well

in listening, speaking, reading and writing, you will learn English well.

First, we must find a good method to learn English. I believe in determination

and hard work. As the saying goes “Nothing is difficult if you put you heart into it”.

As a student, in class, we should listen to the teacher carefully and make notes

carefully. In your spare time, you can often listen to English programs in the radio or

watch programmers on TV. For example, you can watch English movies, and listen to

Abstract: With the continual reform of language teaching and learning

methods, teachers are required to organize the classes in English and

create English-learning environments. However, with the limitation of

students' vocabulary, teachers have to simplify their teaching language

with the help of Body Language . This paper points out some mistakes that

English teachers have made in the classroom ; explains the importance

of Body Language in English teaching, from the four parts of Eyesight,

Countenance, Gesture and Manner ; illustrates how teachers should

properly use Body Language by examples and shows various kinds of Body

Languge used in English teaching . Teaching English with the help of Body

How to Learn English Well？

Everyone wants to learn English well, but how can we learn it well? It’s a good topic for English learner. If you know some good methods, they can help you improve your English level quickly. As far as

I'm concerned, the followings are necessary:

First of all, you must have correct attitude, please love English, and not hate it. And you don’t feel shy when you say or speak English. Remember one sentence: Put your face in your pocket. We should know the importance of learning it. English is the most wildly used international language in the world. Secondly, I think grammar rules, new words and phrases are important, but they are not enough. For example, some people are quite good at grammars and learned a lot of English words and phrases by heart，But they can’t speak English when they meet foreign friends. The best way to learn English well is use English as possible as you can. Don’t be afraid and don’t laugh at others. We’d better listen, speak, read and write more. You can go to English corner, talk with foreigner or talk with your friends. If you

波传感器、雷达传感器等，这些传感器可　以采集监测区域的各种信息，包括温度、　湿度、雷达传感器等，这些车辆运动、光照　条件、压力、土壤成分、噪声电平、监测目　标的消失和出现、监测目标的机械强度、　监测目标的运动特征等。　传感器节点可以连续不断地进行数　据采集、事件检测、事件标识、位置监测和　节点控制，传感器节点的这些特性和无线　连接方式使得无线传感器网络的应用前　景非常广阔，能够广泛应用于军事、环境　监测和预报、健康护理、智能家居、建筑物　状态监控、复杂机械监控、城市交通、空间　探索、大型车间和仓库管理，以及机场、大　型工业园区的安全监测等领域。随着无线　传感器网络的深人研究和广泛应用，无线　传感器网络将逐渐深入到人类生活的各　个领域　四、蓝牙网络　“蓝牙”（Ｂｌｕｅｔｏｏｔｈ）原是十世纪统一　了丹麦的国王的名字，现取其“统一”的含　义，用来命名意在统一无线局域网通讯标　准的蓝牙技术。　蓝牙是无线数据和语音传输的开放　式标准，它将各种通信设备、计算机及其　终端设备、各种数字数据系统、甚至家用　电器采用无线方式联接起来。它的传输距　离为１０ｃｍ～１Ｏｍ，如果增加功率或是加　上某些外设便可达到ｌＯＯｍ的传输距离。　它采用２．４ＧＨｚＩＳＭ频段和调频、跳频技　术，使用权向纠错编码、ＡＲＱ、ＴＤＤ和基　带协议。ＴＤＭＡ每时隙为０．６２５￣ｓ，基带符　合速率为１Ｍｂ／ｓ。蓝牙支持６４ｋｂ／ｓ实时语　音传输和数据传输，语音编码为ＣＶＳＤ，　发射功率分别为ｌｍＷ、２．５ｍ和ｌＯＯｍＷ，　并使用全球统一的４８比特的设备识别　码。由于蓝牙采用无线接口来代替有线电　缆连接，具有很强的移植性，并且适用于　多种场合，加上该技术功耗低、对人体危　害小，而且应用简单、容易实现，所以易于　推广。　五、ＧＰＲＳ网络　ＧＰＲＳ（Ｇｅｎｅｒａｌ　Ｐａｃｋｅｔ　Ｒａａ￣ｏ　Ｓｅｒｖｉｃｅ）　是通用分组无线业务的简称，它是第２．　５代移动通信系统，是ＧＳＭ向３Ｇ过渡的　一个桥梁。ＧＰＲＳ是在ＧＳＭ系统基础上　引入新的部件而构成的无线数据传输系　统。　ＧＰＲＳ是在现有Ｇ卧　系统上发展出　来的一种新的承载业务，目的是为ＧＳＭ　用户提供分组形式的数据业务。ＧＰＲＳ采　用与ＧＳＭ同样的无线调制标准、同样的　频带、同样的突发结构、同样的跳频规则　以及同样的ＴＤＭＡ帧结构，这种新的分　组数据信道与当前的电路交换的话音业　务信道极其相似。因此，现有的基站子系　统　ｓ　从～开始就可提供全面的ＧＰＲＳ　覆盖。ＧＰＲＳ允许用户在端到端分组转移　模式下发送和接收数据，而不需要利用电　路交换模式的网络资源，从而提供了一种　高效、低成本的无线分组数据业务。特别　适用于间断的、突发性的和频繁的、少量　的数据传输，也适用于偶尔的大数据量传　输。　ＧＰＲＳ理论带宽可达１７１．２Ｋｂ／ｓ，实际　应用带宽大约在１０～７０Ｋｂ／ｓ，在此信道上　提供ＴＣｐ／ＩＰ连接，可以用于ｌｎｔｅｒｎｅｔ连　接、数据传输等应用。ＧＰＲＳ是一种新的　移动数据通信业务，在移动用户和数据网　络之间提供一种连接，给移动用户提供高　“ｊ　持ｉ　种ｔ　癸　张秘　速无线／Ｐ。ＧＰＲＳ采用分组交换技术，每　个用户可同时占用多个无线信道，同一无　线信道又可以由多用户共享，资源被有效　的利用。使用ＧＰＲＳ技术实现数据分组发　送和接收，用户保持理论上的永远在线并　且按流量进行计费，迅速降低了服务成　本。　ＰＲｓ（Ｇｅｎｅｒａｌ　Ｐａｃｋｅｔ　Ｒａｄｉｏ　Ｓｅｒｖｉｃｅ．　通用分组无线业务）是在现有的ＧＳＭ移　动通信系统基础上发展起来的一种移动　分组数据业务，是ＧＳＭ网络向第三代移　动通信演进的第一步，这一步有两点重要　意义：一是在ＧＳＭ网络中引入分组交换　能力；二是将速率提高到１１５ｋｂｉｔ／ｓ以上。　通过在ＧＳＭ数字移动通信网中引入　分组交换的实体组成ＧＳＭ—ＧＰＲＳ网络，　实现以分组方式进行的数据传输，同时尽　量减少对ＧＳＭ网络的改动。ＧＰＲＳ可以　看作是原有的ＧＳＭ电路交换系统的基础　上进行的业务扩充：由新增的网络实体对　ＧＳＭ数据进行旁路，支持移动用户利用　分组数据移动终端接入Ｉｎｔｅｒｎｅｔ或其他　分组数据网络。　参考文献　［１】李林，刘毅，杨骏．无线网络安全风险评估　方法的应用研究［Ｊ］．计算机仿真，２０１１－９：　１４７—１　５Ｏ．　【２］张卫旭，尉宇．基于密度的局部离群点检　测算法［Ｊ］．计算机与数字工程，２０１０，３８　（１０）：１１・１４．　【３］薛安荣，等．局部离群点挖掘算法研究【Ｊ】．　计算机学报，２００７，３Ｏ（８）：１４５—１４５８．
