An old man walked into a pet shop one day with a large and very ugly dog.It had long hair, short legs, no tail and a very wet nose.“Good morning, sir,” the owner of the pet shop said. “How can I help you?”“I want to sell this dog.”The pet shop owner looked at the dog and shook his head.“I"m sorry. I can"t give you anything for that animal. No one will want to buy him.”“Why not?” asked the man. “He"s clean, well-behaved and healthy.”“Look at him, sir,” said the pet shop owner. “He hasn"t got a tail, his legs are too short and his hair"s too long. Who would want to buy such a dog?”“Well, I guess you"re right,” the man said. “But he can talk.”“What do you mean he can talk?” the pet stop owner asked.“Yes, he can speak perfect Mandarin (普通话), different Chinese dialects, English and Japanese as well. Just listen,” the man answered.The dog then spoke.“It"s true, sir,” he said. “I am the world"s greatest talking dog. I"ve been to America and talked to the President Bush at the White House in Washington. I"ve talked to the Queen of England and the Emperor of Japan. Please buy me, sir. This man is very cruel to me. He makes me work too hard and doesn"t feed me very well. He never takes me for a walk or gives me a bath. Sometimes he leaves me alone for weeks. I"m so unhappy, sir. Please buy me and find a good home for me.”The pet shop owner could hardly believe what he was hearing.“That"s amazing ,” he said. “You"re right. He is a talking dog. But tell me, why do you want to sell him?”“Because I"m tired of all his lies,” the man said

Important of the Marketing Strategies for the company
Marketing strategy is a key part of the general corporate strategy A marketing strategy is most effective when it is an integral ponent of corporate strategy, defining how the anization will engage customers, prospects and petitors in the market arena for success. It is partially derived from broader corporate strategies, corporate missions, and corporate goals. They should flow from the firm"s mission statement. They are also influenced by a range of microenvironmental factors. A marketing strategy also serves as the foundation of a marketing plan. A marketing plan contains a set of specific actions required to successfully implement a marketing strategy. For example: "Use a low cost product to attract consumers. Once our anization, via our low cost product, has established a relationship with consumers, our anization will sell additional, higher-margin products and services that enhance the consumer"s interaction with the low-cost product or service." Here are different type of marketing strategies, and it will clearly explain different marketing strategies have different important function on marketing activities: Types of marketing strategies Every marketing strategy is unique, but if we abstract from the individualizing details, each can be reduced into a generic marketing strategy. There are a number of ways of categorizing these generic strategies. A brief description of the most mon categorizing schemes is presented below: Strategies based on market dominance - In this scheme, firms are classified based on their market share or dominance of an industry. Typically there are three types of market dominance strategies: Leader Challenger Follower this strategy base on internal management Porter generic strategies - strategy on the dimensions of strategic scope and strategic strength. Strategic scope refers to the market peration while strategic strength refers to the firm"s sustainable petitive advantage. Cost leadership Product differentiation Market segmentation this strategy apply porter theory to place effort on target market and positioning. Innovation strategies - This deals with the firm"s rate of the new product development and business model innovation. It asks whether the pany is on the cutting edge of technology and business innovation. There are three types: ------Pioneers ------Close followers -------Late followers this strategies production development Growth strategies - In this scheme we ask the question, “How should the firm grow?”. There are a number of different ways of wering that question, but the most mon gives four wers: ----Horizontal integration ----Vertical integration ----Diversification ----Intensification this strategy based on grow of the firm.,参考: wers/topic/marketing-strategy,Hi some quick thought on it: 1) Help pany identify prospective client 2) Able to help pany generate more revenue 3) Improve pany"s efficiency in terms of operation cost 4) Help pany define or find out their position in the market 5) Identify petitor in the market I think best of all...is to generate REVENUE....REVENUE...,

怎样写testbench
如何编写testbench的总结?1.激励的设置相应于被测试模块的输入激励设置为reg型,输出相应设置为wire类型,双向端口inout在测试中需要进行处理。方法1:为双向端口设置中间变量inout_reg作为该inout的输出寄存,inout口在testbench中要定义为wire型变量,然后用输出使能控制传输方向。eg:inout [0:0] bi_dir_port;wire [0:0] bi_dir_port;reg [0:0] bi_dir_port_reg;reg bi_dir_port_oe;assign bi_dir_port=bi_dir_port_oe?bi_dir_port_reg:1"bz;用bi_dir_port_oe控制端口数据方向,并利用中间变量寄存器改变其值。等于两个模块之间用inout双向口互连。往端口写(就是往模块里面输入)方法2:使用force和release语句,这种方法不能准确反映双向端口的信号变化,但这种方法可以反映块内信号的变化。具体如示:module test();wire data_inout;reg data_reg;reg link;#xx; //延时force data_inout=1"bx; //强制作为输入端口...............#xx;release data_inout; //释放输入端口endmodule从文本文件中读取和写入向量1)读取文本文件:用 $readmemb系统任务从文本文件中读取二进制向量(可以包含输入激励和输出期望值)。$readmemh 用于读取十六进制文件。例如:reg [7:0] mem[1:256] // a 8-bit, 256-word 定义存储器meminitial $readmemh ( "mem.data", mem ) // 将.dat文件读入寄存器mem中initial $readmemh ( "mem.data", mem, 128, 1 ) // 参数为寄存器加载数据的地址始终2)输出文本文件:打开输出文件用?$fopen 例如:integer out_file; // out_file 是一个文件描述,需要定义为 integer类型out_file = $fopen ( " cpu.data " ); // cpu.data 是需要打开的文件,也就是最终的输出文本设计中的信号值可以通过$fmonitor, $fdisplay,2. Verilog和Ncverilog命令使用库文件或库目录ex). ncverilog -f run.f -v lib/lib.v -y lib2 +libext+.v //一般编译文件在run.f中, 库文件在lib.v中,lib2目录中的.v文件系统自动搜索使用库文件或库目录,只编译需要的模块而不必全部编译3.Verilog Testbench信号记录的系统任务:1). SHM数据库可以记录在设计仿真过程中信号的变化. 它只在probes有效的时间内记录你set probe on的信号的变化.ex). $shm_open("waves.shm"); //打开波形数据库$shm_probe(top, "AS"); // set probe on "top",第二个参数: A -- signals of the specific scrope S -- ports of the specified scope and below, excluding library cellsC -- ports of the specified scope and below, including library cellsAS -- Signals of the specified scope and below, excluding library cellsAC -- Signals of the specified scope and below, including library cells还有一个 M ,表示当前scope的memories, 可以跟上面的结合使用, "AM" "ams" "amc"什么都不加表示当前scope的ports;$shm_close //关闭数据库2). VCD数据库也可以记录在设计仿真过程中信号的变化. 它只记录你选择的信号的变化.ex). $dumpfile("filename"); //打开数据库$dumpvars(1, top.u1); //scope = top.u1, depth = 1第一个参数表示深度, 为0时记录所有深度; 第二个参数表示scope,省略时表当前的scope.$dumpvars; //depth = all scope = all$dumpvars(0); //depth = all scope = current$dumpvars(1, top.u1); //depth = 1 scope = top.u1$dumpoff //暂停记录数据改变,信号变化不写入库文件中$dumpon //重新恢复记录3). Debussy fsdb数据库也可以记录信号的变化,它的优势是可以跟debussy结合,方便调试.如果要在ncverilog仿真时,记录信号, 首先要设置debussy:a. setenv LD_LIBRARY_PATH :$LD_LIBRARY_PATH(path for debpli.so file (/share/PLI/nc_xl//nc_loadpli1))b. while invoking ncverilog use the +ncloadpli1 option.ncverilog -f run.f +debug +ncloadpli1=debpli:deb_PLIPtrfsdb数据库文件的记录方法,是使用$fsdbDumpfile和$fsdbDumpvars系统函数,使用方法参见VCD注意: 在用ncverilog的时候,为了正确地记录波形,要使用参数: "+access+rw", 否则没有读写权限在记录信号或者波形时需要指出被记录信号的路径,如:tb.module.u1.clk.………………………………………………………………………………………………………关于信号记录的系统任务的说明:在testbench中使用信号记录的系统任务,就可以将自己需要的部分的结果以及波形文件记录下来(可采用sigalscan工具查看),适用于对较大的系统进行仿真,速度快,优于全局仿真。使用简单,在testbench中添加:initial begin$shm_open("waves.shm");$shm_probe("要记录信号的路径“,”AS“);#10000$shm_close; 即可。4. ncverilog编译的顺序: ncverilog file1 file2 ....有时候这些文件存在依存关系,如在file2中要用到在file1中定义的变量,这时候就要注意其编译的顺序是从后到前,就先编译file2然后才是file2.5. 信号的强制赋值force首先, force语句只能在过程语句中出现,即要在initial 或者 always 中间. 去除force 用 release 语句.initial begin force sig1 = 1"b1; ... ; release sig1; endforce可以对wire赋值,这时整个net都被赋值; 也可以对reg赋值.6.加载测试向量时,避免在时钟的上下沿变化为了模拟真实器件的行为,加载测试向量时,避免在时钟的上下沿变化,而是在时钟的上升沿延时一个时间单位后,加载的测试向量发生变化。如:assign #5 c=a^b……@(posedge clk) #(0.1*`cycle) A=1;******************************************************************************//testbench的波形输出module top;...initialbegin$dumpfile("./top.vcd"); //存储波形的文件名和路径,一般是.vcd格式.$dumpvars(1,top); //存储top这一层的所有信号数据$dumpvars(2,top.u1); //存储top.u1之下两层的所有数据信号(包含top.u1这一层)$dumpvars(3,top.u2); //存储top.u2之下三层的所有数据信号(包含top.u2这一层)$dumpvars(0,top.u3); //存储top.u3之下所有层的所有数据信号endendmodule//产生随机数,seed是种子$random(seed);ex: din <= $random(20);//仿真时间,为unsigned型的64位数据$timeex:...time condition_happen_time;...condition_happen_time = $time;...$monitor($time,"data utput = %d", dout);...//参数parameter para1 = 10,para2 = 20,para3 = 30;//显示任务$display();//监视任务$monitor();//延迟模型specify...//describ pin-to-pin delayendspecifyex:module nand_or(Y,A,B,C);input A,B,C;output Y;AND2 #0.2 (N,A,B);OR2 #0.1 (Y,C,N);specify(A*->Y) = 0.2;(B*->Y) = 0.3;(C*->Y) = 0.1;endspecifyendmodule//时间刻度`timescale 单位时间/时间精确度//文件I/O1.打开文件integer file_id;file_id = fopen("file_path/file_name");2.写入文件//$fmonitor只要有变化就一直记录$fmonitor(file_id, "%format_char", parameter);eg:$fmonitor(file_id, "%m: %t in1=%d o1=%h", $time, in1, o1);//$fwrite需要触发条件才记录$fwrite(file_id, "%format_char", parameter);//$fdisplay需要触发条件才记录$fdisplay(file_id, "%format_char", parameter);$fstrobe();3.读取文件integer file_id;file_id = $fread("file_path/file_name", "r");4.关闭文件$fclose(fjile_id);5.由文件设定存储器初值$readmemh("file_name", memory_name"); //初始化数据为十六进制$readmemb("file_name", memory_name"); //初始化数据为二进制//仿真控制$finish(parameter); //parameter = 0,1,2$stop(parameter);//读入sdf文件$sdf_annotate("sdf_file_name", module_instance, "scale_factors");//module_instance: sdf文件所对应的instance名.//scale_factors:针对timming delay中的最小延时min,典型延迟typ,最大延时max调整延迟参数//generate语句,在Verilog-2001中定义.用于表达重复性动作//必须事先声明genvar类型变量作为generate循环的指标eg:genvar i;generate for(i = 0; i < 4; i = i + 1)beginassign = din[i] = i % 2;endendgenerate//资源共享always @(A or B or C or D)sum = sel ?

如何编写testbench的总结
1.激励的设置相应于被测试模块的输入激励设置为reg型,输出相应设置为wire类型,双向端口inout在测试中需要进行处理。方法1:为双向端口设置中间变量inout_reg作为该inout的输出寄存,inout口在testbench中要定义为wire型变量,然后用输出使能控制传输方向。eg:inout [0:0] bi_dir_port;wire [0:0] bi_dir_port;reg [0:0] bi_dir_port_reg;reg bi_dir_port_oe;assign bi_dir_port=bi_dir_port_oe?bi_dir_port_reg:1"bz;用bi_dir_port_oe控制端口数据方向,并利用中间变量寄存器改变其值。等于两个模块之间用inout双向口互连。往端口写(就是往模块里面输入)方法2:使用force和release语句,这种方法不能准确反映双向端口的信号变化,但这种方法可以反映块内信号的变化。具体如示:module test();wire data_inout;reg data_reg;reg link;#xx; //延时force data_inout=1"bx; //强制作为输入端口...............#xx;release data_inout; //释放输入端口endmodule从文本文件中读取和写入向量1)读取文本文件:用 $readmemb系统任务从文本文件中读取二进制向量(可以包含输入激励和输出期望值)。$readmemh 用于读取十六进制文件。例如:reg [7:0] mem[1:256] // a 8-bit, 256-word 定义存储器meminitial $readmemh ( "mem.data", mem ) // 将.dat文件读入寄存器mem中initial $readmemh ( "mem.data", mem, 128, 1 ) // 参数为寄存器加载数据的地址始终2)输出文本文件:打开输出文件用?$fopen 例如:integer out_file; // out_file 是一个文件描述,需要定义为 integer类型out_file = $fopen ( " cpu.data " ); // cpu.data 是需要打开的文件,也就是最终的输出文本设计中的信号值可以通过$fmonitor, $fdisplay,2.

sql server中的 schemes啥意思
schemes就是属于哪个组。-为登陆账户创建数据库用户(create user),在mydb数据库中的security中的user下可以找到新创建的dbacreate user dba for login dba with default_schema=dbo并指定数据库用户“dba” 的默认 schema 是“dbo”。这意味着 用户“dba” 在执行“select * from t”,实际上执行的是 “select * from dbo.t”。
ich kenne es nicht
Nein 表示否定 不是占位,也不占位;表达否定的nicht占位 举个例子:Ich gehe morgen.表示我明天走. 如果改成:Ich gehe nicht morgen.我不是明天走.(我一定走) 再改成:Ich gehe morgen nicht.我明天不走.(但是我走不走不一定.) 不同的位置,nicht否定的内容不同. 后面 ihn kenne ich nicht.这里没有倒装出现 只是宾语前置 表示强调 这里强调“他” 倒装一般出现在第二虚拟式的情况下 比如一些表达愿望的句子,或者一些假设 比如: Wenn es morgen regnen wuerde,. 倒装成 Wuerde es morgen regnen,.当你看到这样的句子,不要以为它是问句,它是一个倒装 在英语里也有这样的语法,在if的句子,把动词提前,可以省略if,句子的意思不变
schema和tablespace究竟是干什么用的
remap_schema当你从A用户导出的数据,想要导入到B用户中去,就使用这个:remap_schema=A:B remap_tablespace 与上面类似,数据库对象本来存在于tbs_a表空间,现在你不想放那儿了,想换到tbs_b,就用这个remap_tablespace=tbs_a:tbs_b 结果是所有.

在开机自检画面中,会出现“Memory test fail(内存检测失败)”的错误提示信息
CMOS battery failedCMOS电池失效。一般出现这种情况就是说明给主板CMOS供电的电池已经快没电了,需要朋友们及时更换主板电池。 CMOS check sum error-Defaults loadedCMOS执行全部检查时发现错误,要载入系统预设值。一般来说出现这句话有两种解释:一种是说主板CMOS供电电池快要没电了,朋友们可以先换个电池试试看;第二种解释是如果更换电池后问题还是没有解决,那么就说明CMOS RAM可能有问题了,如果主板没过一年的话就可以到经销商处换一块主板,要是过了一年就让经销商送回生产厂家修一下吧!Floppy Disk(s) fail 或 Floppy Disk(s) fail(80) 或Floppy Disk(s) fail(40)无法驱动软盘驱动器。系统提示找不到软驱,首先要看看软驱的电源线和数据线有没有松动或者是接反,最好是是把软驱放到另外一台机子上试一试,如果这些都不行,那么只好再买一个了,好在目前市场中的软驱还不算贵。Hard disk install failure硬盘安装失败。这是因为硬盘的电源线或数据线可能未接好或者硬盘跳线设置不当引起的。朋友们可以检查一下硬盘的各根连线是否插好,看看同一根数据线上的两个硬盘的跳线设置是否一样。如果一样,只要将两个硬盘的跳线设置不一样即可(一个设为Master,另一个设为Slave)。Hard disk(s) diagnosis fail执行硬盘诊断时发生错误。出现这个问题一般就是硬盘内部本身出现硬件故障了,你可以把硬盘放到另一台机子上试一试,如果问题还是没有解决,只能去修一下了。如果硬盘还在包换期内的话,最好还是赶快去换一块!Hardware Monitor found an error,enter POWER MANAGEMENT SETUP for details,Press F1 to continue,DEL to enter SETUP监视功能发现错误,进入POWER MANAGEMENT SETUP查看详细资料,或按F1键继续开机程序,按DEL键进入CMOS设置。现在好一些的主板都具备有硬件的监视功能,用户可以设定主板与CPU的温度监视、电压调整器的电压输出准位监视和对各个风扇转速的监视,当上述监视功能在开机时发觉有异常情况,那么便会出现这段话,这时朋友们可以进入CMOS设置选择POWER MANAGEMENT SETUP,在右面的**Fan Monitor**、**Thermal Monitor**和**Voltage Monitor**查看是哪部分监控发出了异常情况,然后再加以解决。Keyboard error or no keyboard present键盘错误或者未接键盘。检查一下键盘与主板接口是否接好,如果键盘已经接好,那么就是主板键盘口坏了,主板如尚在包修期内,朋友们可以找经销商或主板厂家进行解决。Memory test fail内存检测失败。重新插拔一下内存条,看看是否能解决,出现这种问题一般是因为混插的内存条互相不兼容而引起的,有条件的话去换一条吧!如果使用的只是一根内存条,那么就一定是内存条本身有问题,还是赶快去换一条的好!Override enable-Defaults loaded当前CMOS设定无法启动系统,载入BIOS中的预设值以便启动系统。一般是CMOS内的设定出现错误,朋友们只要进入CMOS设置后选择LOAD SETUP DEFAULTS载入系统原来的设定值然后重新启动即可解决这一问题。Press ESC to skip memory test正在进行内存检查,可按ESC键跳过。这是因为在CMOS内没有设定跳过存储器的第二、三、四次测试,开机就会执行四次内存测试,当然你也可以按ESC键结束内存检查,不过每次开机后都要这样做实在太麻烦了,你可以进入CMOS设置后选择BIOS FEATURES SETUP,将其中的Quick Power On Self Test设为Enabled开启,存储后重新启动即可解决。
prime polished wafer, EPI wafer, Test/Monitor wafer 分别是什么?
Prime wafer是产品级硅片,是生产集成电路或其他半导体产品的硅片。Prime wafer分为两种,抛光片(polished wafer)和外延片(EPI wafer)。抛光片是在硅片抛光,达到很高平坦度,但缺陷和杂质距离生产高端产品还有距离。这种硅片一般500元人民币一片EPI wafer是外延片,是在抛光片的基础上沉积一层外延层,一般几个微米厚。这个厚度足够制作器件。同时这个外延层中杂质和晶格缺陷都更少,掺杂浓度也更精确,因此可以生产高端产品。这种片子估计一片600元吧。Test wafer和Monitor wafer是一种硅片的不同用途。这种硅片缺陷更多,掺杂波动范围更大,杂质也更多总之,就是次一个档次的硅片,一般200元一片。工程师做实验时多数用Test wafer,够用,又便宜。设备做点检时就用点检晶圆(Monitor wafer)。这两种情况完全可以用Polish wafer甚至是EPIwafer,但就是贵,浪费钱,没必要。

iOS应用间通信:URL Schemes
URL用于定位资源,譬如网络资源。以下面的URL为例: 根据 RFC1808 标准,其包含如下组成部分: iOS中,你可以为自己的应用定义URL schemes,供外界调用。URL格式必须符合标准(即能够通过 NSURL 解析)。 总体来说,URL schemes可划分为两类:系统定义&自定义。 有些系统应用天生支持URL schemes,例如电话,邮件,短信,Safari,地图等。 更多关于系统定义的URL schemes的信息,详见官方文档 Apple URL Scheme Reference 。 调用URL scheme其实很简单,分为两步: 注意事项: 打开URL的方法如下: 自定义URL schemes也可以分为两步: iOS以URL type为单位管理URL schemes。一个type下可以有多个scheme,但一个scheme只对应一个type。注册URL schemes,实际上是注册URL type。 在 Info.plist 中添加键值对 CFBundleURLTypes ,其对应一个数组,每个元素都是一个字典,代表一个type。例如: 一个URL type字典包含如下键值对: 更多关于CFBundleURLTypes的信息,详见Information Property List Key Reference中章节 CFBundleURLTypes 的叙述。 此外,还可以针对scheme定义启动图片。众所周知,app启动时会显示图片。如果app因为响应某个scheme而启动,可以根据scheme定义图片。图片命名格式如下: 更多关于URL scheme启动图片的信息,详见App Programming Guide for iOS中章节 Displaying a Custom Launch Image When a URL is Opened 的叙述。 收到调用请求后,相应的UIApplication代理方法会被调用,所以这里也是处理逻辑的所在: 注意事项: 被调用时,app可能处于下列状态之一: D.2.2.1 app未运行时被调用 app先启动,再处理请求,但受到下面方法影响: D.2.2.1 app运行中被调用 app 必定 会处理请求,进入前台(即方法 application:openURL:options: 一定会被调用); UIApplication方法 canOpenURL: 可以判断当前设备上是否有能够响应特定URL的应用。 于是乎,有人利用这个方法过滤大量scheme,判断设备上安装了哪些应用。为防止滥用,自iOS9,Apple要求这个方法只能检测特定名单内的scheme(当然,系统定义的scheme不在此列),开发者需要通过键值对 LSApplicationQueriesSchemes 在 Info.plist 中定义这个名单。例如: 另外,还要注意: 更多关于LSApplicationQueriesSchemes的信息,详见Information Property List Key Reference中章节 LSApplicationQueriesSchemes 的叙述。

急求高一英语必修三Unit1 festivals around the world的原文
必修3 unit1Festivals and celebrations Festivals and celebrations of all kinds have been held everywhere since ancient times. Most ancient festivals would celebrate the end of cold weather, planting in spring and harvest in autumn. Sometimes celebrations would be held after hunters had caught animals. At that time people would starve if food was difficult to find, especially during the cold winter months. Today"s festivals have many origins, some religious, some seasonal, and some for special people or events.Festivals of the Dead Some festivals are held to honour the dead or to satisfy the ancestors, who might return either to help or to do harm. For the Japanese festival Obon, people should go to clean graves and light incense in memory of their ancestors. They also light lamps and play music because they think that this will lead the ancestors back to earth. In Mexico, people celebrate the Day of the Dead in early November. On this important feast day, people eat food in the shape of skulls and cakes with "bones" on them. They offer food, flowers and gifts to the dead. The Western holiday Halloween also had its origin in old beliefs about the return of the spirits of dead people. It is now a children"s festival, when they can dress up and go to their neighbours" homes to ask for sweets. If the neighbours do not give any sweets, the children might play a trick on them.Festivals to Honour People Festivals can also be held to honour famous people.

course与lesson,program如何区别
course是一门课程。比如说语文,数学。 lesson是一节课,更准确的说,是一节课的内容。program是只表演的节目
英文中"course"和"lesson"的区别在哪?
class是最口语化的课,一般意义上的上课take class,have class而course是课程,更具体也更正式,比如你在大学是读些什么课程的就要用course而lesson与class基本相同,有些时候可以互换,但是前class侧重于课业的形式,而lesson侧重于课业的内容。比如说:“I have two classes this afternoon.”时,讲话人所强调的是“两个45分钟”的课业形式,而当他说:“I have two lessons this afternoon.”时,则着重强调“两个学科”的课业内容。curriculum则侧重于总体学科,是一个概括性的词汇
in 1492,Columbus and his crew arrived ___was so called the New World by the westerners.
不能,答案是:in what.解释:1. 根据句意和结构可知,what was so called the New World by the westerners为介词in的宾语,即宾语从句。arrive是不及物动词,不能直接加宾语(从句),所以必须先加一个介词in(the New World为大地方,所以用in最合适)。2. 该宾语从句明显缺少表示事物sth的主语,所以用what代替并引导此从句。which一般用于定语从句,但是此时从句前面没有表示地方的名词/代词即没有先行词,排除;which如果引导宾语从句,则其意思是“哪一个/些”,则该从句前后必须有限定的范围方可,排除。如:I wonder which you like best of all these colors. 其中of all these colors即为限定范围。

Currently there is an ongoing discussion about whether we should go shopping online. Personally I believe that by making good use of online shopping, we can get various products that are possibly not available in a traditional store. By browsing the products online, we can easily and conveniently choose the ones we like and get them paid and delivered without going out of room. In addition, the products are always cheaper than the ones in a traditional store. However, the disadvantage of online shopping is that sometimes we may not actually see the products until we receive them, which I think we may have the chance to buy something inferior. Although sometimes there may be potential risks for online shopping, there is no doubt that it is of great benefit and convenience for us to go shopping online. 5. 以“travelling online”为题写一篇字数80~90词的作文,急 "People who like travelling have their reasons.

However some people hold disapproval attitudes towards this thing. In my opinion, it both has positive and negative aspects, just as the proverb goes like this: every coin has o sides. When it es to positive aspects, it"s very convenient and time-saving pared with traditional shopping. What you need to do is just clicking your mouse and waiting instead of going out by foot or driving. Moreover, more choices than real store are another attraction to customers. However, in spite of convenience and more choices of online shopping, we cannot turn a blind eye to its advantages. Obviously, quality problem is its first advantage. It"s mon that articles aren"t so good just as they are described online that customers always buy fake modities. What"s more, it"s troublesome and annoying for many customers to make a change when they are not satisfied with what they bought online. To make a better environment for shopping on-line, effective measures should be taken to make it better. Specifically speaking, government should work out strict regulations and rules to prevent unfaithful and unlawful activities of online shopping owners. Only by this way can online shopping bee really safe and attract an increasing number of customers 8. 谁现在能帮我写篇作文~~ "online learning" ~~字数100 The Inter as a Beneficial Learning Tool for Students The Inter, monly referred to as the “information superhighway,” is a tool that has been introduced to classrooms around the world because of its popularity, which has been gaining steadily in the past years.
