  • its a good honor for me to introduce my reading experience to you. Not long age, I got NO.1 in the English Reading Contest of our school. Now I want to share my experience with you.As we all know, practice makes perfect, so I attach great importance to reading a lot, which is the best way to improve our reading ability. I often read some English newpapers and magazines such as China Daily, Readers Digest and so on. I can also learn some useful words and expressions while reading, which has helped me a lot in return. Besides, I am always trying to use some important skills that are taught in our English lessones, such as skimming and scanning. With these correct methods, we can improve our reading greatly.All it requires is plenty of practices with the proper techniques. Only in this way we can develop our reading skills efficiently.有些错误用法之处稍作修改,anyway,希望能够帮到你!

l think it was my mother中的宾语从句的引导词是什么?

  • l think it was my mother中的宾语从句的引导词是什么?
  • 宾语从句。意思:我认为这可能是一个玩笑。一、宾语从句定义:置于动词、介词等词性后面起宾语作用的从句叫宾语从句。宾语从句的语序必须是陈述语序。谓语动词、介词、动词不定式,v.-ing形式后面都能带宾语从句。有些形容(afraid,sure,glad等)之后也可以带宾语从句。二.宾语从句中引导词的用法在复合句中作主句的宾语,引导词有:连词:that (that 常可省略),whether, if代词:who, whose, what ,which副词:when ,where, how, why 等。(一)that引导的宾语从句(在非正式场合that可以省略)可跟that从句做宾语的动词有:say, think, insist, wish, hope, demand, imagine, wonder, know, suppose, see, believe, agree, admit, deny, expect, explain, order, command, feel, dream, suggest, hear, mean, notice, prefer, request, require, propose, declare, report等。例句:The boy believes that he will travel through space to other planets.注意事项:当主句谓语动词是 think, believe, suppose, expect 等词,而宾语从句的意思是否定时,常把否定转移至主句表示。例句:I don’t think it is right for him to treat 虎窢港喝蕃估歌台攻郡you like that.

如何在Windows下开发NodeJS的CC++原生扩展

  • 如何在Windows下开发NodeJS的CC++原生扩展
  • 一、编写Node.js原生扩展Node.js是一个强大的平台,理想状态下一切都都可以用javascript写成。然而,你可能还会用到许多遗留的库和系统,这样的话使用c++编写Node.JS扩展会是一个不错的注意。以下所有例子的源代码可在node扩展示例中找到 。编写Node.js C + +扩展很大程度上就像是写V8的扩展; Node.js增加了一些接口,但大部分时间你都是在使原始的V8数据类型和方法,为了理解以下的代码,你必须首先阅读V8引擎嵌入指南。Javascript版本的Hello World在讲解C++版本的例子之前,先让我们来看看在Node.js中用Javascript编写的等价模块是什么样子。这是一个最简单的Hello World,也不是通过HTTP,但它展示了node模块的结构,而其接口也和大多数C++扩展要提供的接口差不多:HelloWorldJs = function() { this.m_count = 0;};HelloWorldJs.prototype.hello = function(){ this.m_count++; return “Hello World”;};exports.HelloWorldJs = HelloWorldJs;正如你所看到的,它使用prototype为HelloWorldJs类创建了一个新的方法。请注意,上述代码通过将HelloWorldJS添加到exports变量来暴露构造函数。要在其他地方使用该模块,请使用如下代码:var 涪缉帝垦郜旧佃驯顶沫helloworld = require(‘helloworld_js’);var hi = new helloworld.HelloWorldJs();console.log(hi.hello()); prints “Hello World” to stdoutC++版本的Hello World要开始编写C++扩展,首先要能够编译Node.js(请注意,我们使用的是Node.js 2.0版本)。本文所讲内容应该兼容所有未来的0.2.x版本。一旦编译安装完node,编译模块就不在需要额外的东西了。完整的源代码可以在这里找到 。在使用Node.js或V8之前,我们需要包括相关的头文件:#include v8.h#include node.husing namespace node;using namespace v8;在本例子中我直接使用了V8和node的命名空间,使代码更易于阅读。虽然这种用法和谷歌的自己的C++编程风格指南相悖,但由于你需要不停的使用V8定义的类型,所以目前为止的大多数node的扩展仍然使用了V8的命名空间。接下来,声明HelloWorld类。它继承自node::ObjectWrap类 ,这个类提供了几个如引用计数、在V8内部传递contex等的实用功能。一般来说,所有对象应该继承ObjectWrap:class HelloWorld: ObjectWrap{private: int m_count;public:声明类之后,我们定义了一个静态成员函数,用来初始化对象并将其导入Node.js提供的target对象中。设个函数基本上是告诉Node.js和V8你的类是如何创建的,和它将包含什么方法:static Persistent&l……余下全文

node.js与html,mysql交互

  • 现在有一个node.js文件可以实现同mysql交互,并在控制台输出查询结果,如何将这个.js文件同另一个html文件建立起联系?比如监听端口为8000,打开localhost:8000后显示出另一个html的内容,点击页面按钮后可以显示出查询结果。查了一下说是用ajax传递json数据可以实现,求解答与数据库交互的js:var http = require("http");var mysql=require(mysql);var fs = require(fs);var link=mysql.createConnection({host:127.0.0.1,user:root,password:});http.createServer(function (request, response) {link.connect();link.query(use webtest);link.query(select * from web, function(err, res, fields){ if(err){response.writeHead(404, {Content-Type: textplain}); response.write(err); response.end();}else{response.writeHead(200, {"Content-Length": results.length}); response.writeHead(200, {"Content-Type": "applicationjson"}); response.end(res);console.log(res)}response.writeHeader(200, {"Content-Type": "texthtml"}); response.write(html); response.end(); link.end();}).listen(8000);});console.log(Server running at 127.0.0.1:8000/);html页面:htmlheadtitlenode.js testtitlescript src="ajax.googleapis.com/…min.js"scriptscript$(document).ready(function(){ $("#button").click(function(){ var request = $.ajax({ url: "127.0.0.1:8000/", type: "GET", dataType: "json"});request.done(function(dataRcvd) { alert(JSON.stringify(dataRcvd));}); });});scriptheadbodyh1hello world!h1forminput type=submit id=button value=displayformbodyhtml
  • 你需要一种模版工具来辅助你快速完成可视的页面,可以采用ejs或者jade。他们主要负责把数据填充到html文本里,然后返回给前端。你可以研究一下这两个东西,看看选用哪个方便写。ejs的用法就像在html中插入php脚本(亦或是jsp、asp)一样。

简述英语高中语法

  • 英语高中语法
  • 一、非谓语动词 “非谓语动词”可分为动词不定式、动名词和分词。它在句子中的作用很多:除了不作谓语外,它可以充当主语、宾语、表语、定语、状语与复合宾语(主语补语或宾语补语)。有些及物动词后面接不带to的不定式作复合宾语。这些动词归纳如下:一感(feel).二听(hear,listen to),三让(have,1et, make),四看(see,watCh,notice,observe)。再加上help somebody(to)do something和美国英语look at somebody do somthing。还有“二让”属特殊:get somebody to do something 与keep somebody doing。而有些及物动词后面接动名词(the -ing form)作宾语。这些动词归纳为一句话:Papa C makes friends。这是由如下动词的开头字母组成:permit,advise, practise,avoid,consider,mind, allow,keep,enjoy,suggest, finish,risk,imagine,escape,need,delay,stand(忍受)。 为了容易记住,也可以编成顺口溜:“允许完成练习,建议避免冒险,考虑延期逃跑,喜欢保持想象,需要反对忍受”。其相对应的动词依次是:permitallow,finish,practise;advise/suggest, avoid,risk: consider, delay, escape/miss; enjoy/appreciate, keep, imagine; needwant/require,mind. cant help/can’t stand。二、复合句 1、学生最容易混淆的是定语从句与同位语从句的区别。例如:A、The news that our team has won the match is true. (同位语从句) B、The news that he told us surprised everybody here. (定语从句) 关键的区别在于连接或关系代词that:有意义的是定语, 无意义的是同位。因为引导定语从句的that在从句中作主语或 宾语,而引导同位语从句的that只起到连接词的作用。 2、接着容易混淆的是引导定语从句的关系代词that与 which:that之前是不定(代词)、序数(词)、(形容词)最高级:which之前是介词短语与逗号(非限制性)。例如:A、All that we have to do is to practise every day. B、The first lesson that I learned will never be forgotten. C、I have lost my pen,which I like very much. D、The house in front of which there is a garden is my home. 三、It的用法 1、It除了代替人和物以外,还可以作形式主语。而真正的主语(不定式、动名词或从句)则放于谓语或表语之后。例如:It is nor easy to finish the work in two days. 然而有少数表语之后接动名词作真正的主语。这些表语是:无助(no help)、无用(no us……余下全文
