篇一：现在完成时的被动语态 篇一

一、概念

主动语态表示主语为动作的执行者；被动语态表示主语为动作的承受者。现在完成时的被动语态强调过去的动作对现在造成的影响或结果，但主语为动作的承受者，表示“……已经被……”。如：

The new school has been set up. 新学校已经建成了。

二、形式

现在完成时的被动语态的肯定式为：have/ has +been +done。如：

The experiment has been done successfully. 这个实验做得很成功。

现在完成时的被动语态的否定式为：have/ has +not +been +done。如：

Tom’s novel has not been published. 汤姆的小说还没有被出版。

现在完成时的被动语态的一般疑问句需将have /has提到主语的前面。如：

It’s a story about a grateful wife and a helpful husband. It embodies the relationship problem between the couple through portraying the wife’s subtle psychological change. In the beginning, the wife was grateful to marry to a man who let her work. What’s more, all she has to do is asked, the husband would say with a smile. But after days and nights，when the grateful wife looks back at the time with her husband, she finds that this is not her ideal life. The problem is that the husband is too dutiful and lack initiative. Th

根据中文将下列句子译成英文。

1. --你以前来中国参观过吗？--我没有。 -- _______ you ________ China before? Have visited --No,_____ _______. I haven’t 2. 他已经看过关于中国的DVD, 非常喜欢中国的生活。 He _____ _________ the DVD about China has watched and _________ _________ the life in China. has enjoyed 3. 这听起来棒极了！ It ________ ___________! so

have, has 和 do, does 专项练习

Exercise 1: 用 do/ does 填空 1. What ___________ you have?

2. What ___________ your brother have? 3. What ___________ she have?

4. _____________ your parents have a computer? 5. What ___________ Liu Tao have?

Learning tip: 英语王国中有两位“活雷锋”-----do和does。他们俩本身没有实在的意义，但很愿意帮助动词。所以他们俩的名字叫“助动词”。两位分工明确，“does”只管主语为第三人称单数的句子，剩下的都归“do”管。 Exercise 2: 用have/has 填空 1. I ___________ a hat.

2. You _____________ some toy cars. 3. She _____________ a tin-opener.

4. The children and their teacher _____________ many flowers

Joe Sanders has the most beautiful garden in our town. Nearly everybody enters for 'The Nicest Garden Competition ' each year, but Joe wins every time. Bill Frith's garden is larger than Joe's. Bill works harder than Joe and grows more flowers and vegetables, but Joe's garden is more interesting. He has made neat paths and has built a wooden bridge over a pool. I like gardens too, but I do not like hard work. Every year I enter for the

garden competition too, and I always win a little prize for the worst garden in the

MIMO雷达:一个创新理念的时代已经到来

最近研究表明mimo天线系统相对单天线系统能够显著的提高通信系统的性能。波速成型假设天线阵列发射或接收信号之间是高相关的，而mimo概念则利用阵列元上信号之间的独立性。在传统的雷达中，目标闪烁被认为是降低雷达性能的有害参数。Mimo雷达的新颖点则相反，也就是说，它利用目标闪烁来改善雷达性能。在这篇文章中，我们介绍mimo雷达概念。我们所考虑的mimo雷达系统包含一组宽距离隔开的天线元阵列，这样每一个单元能够观察目标的不同方面。接收部分是一个传统的用于DF的阵列。系统的性能分析是基于目标探测的估计均方误差的克拉美罗界形式。结果表明，mimo雷达在DF精度方面有明显的性能改善。

Ⅰ 介绍

雷达探测运动目标或者主动声纳并不稀奇[1,2]，在雷达或主动声纳中，通过全向天线发射一已知波速然后目标朝向一组传感器阵列反射一部分能量，通过所反射的能量估计一些未知的参数，例如，方位，距离，速度。有两种用来估计未知参数的普遍方法，MUSIC 或ML[3]。另外，利用传感器阵列控制波速朝向一固定方向并且搜寻一些能量，本质上和装有定向天线的传统雷达一样。众所周知，利用波速成型技术接收阵列可以控制波速在空间朝向任何方向[4]

A person's job has more effects on his or her happiness than this person's social life does.

Happiness, which is worth pursuing for one's whole life, comes from various resources, such as an expecting gift, an excellent test score, an exciting party, a wonderful marriage and a decent job. As complicated reasons determine whether we live happily, social life becomes the main reason.

Firstly, jobs can be changed while our social life cannot be. The definition of an ideal job is just that you are satisfied with it or not. If

电影《心碎往事》的观后感,文章中的内容都是摘自豆瓣评论。引用请注明豆瓣原作者的出处!

A man has to go away before he comes back. 步入成年世界就像走进一条隧道，通向童年。或许，我们从来没有离开过童年。

人生宛若各自童年的展开和演绎，那时的生活习惯，那时和你生活在一起的人们，一朵花的香味，一串清脆的口哨，都会无声无息地爬满你的生命，紧紧缠绕。

DD的故事不只是印证了长期以来我所笃信的，更描绘出一种巨大的蜕变和割裂，隐藏在看似普通、平常的一切，背后。

13岁的Jimmy正处于人生成长的重要阶段，如片头所说的那样，13岁正是那解锁时美妙的“嘀嗒”声，开启之后那就是人生，你想要了解的整个世界。母亲因父亲的死而整天沉浸在伤痛中不能自拔，看不见儿子的爱和成长。好朋友Pappass，学校的清洁工，又是个智障，善良体贴却无法给渴望成长的Jimmy许多答案。这一切似乎奠定了Jimmy13岁的悲剧。

But you never know who your angel gonna be. Jimmy遇见了Lady，一个整天从女子监狱(名为House of D)窗口跟路人搭讪的女人，但从没亲眼见过她。Lady从镜子的反射里看到下面的一
