英语As常见的几种用法(12篇)
1.英语As常见的几种用法 篇一
as…as 结构用法详解
其基本意思为“与…一样”,其中的第一个as为副词,其后通常接形容词或副词(用原级),第二个as可用作介词(后接名词或代词)或连词(后接从句)。使用时应注意以下几点。如:
(1) 在否定句中,第一个 as 也可换成 so。如:
He doesn’t study as [so] hard as his brother. 他学习不如他弟弟努力。
(2) 在该结构的两个as之间通常接形容词或副词的原级,但若涉及数量或程度,可用“as much+不可数名词+as”和“as many+复数名词+as”。如:
You’ve made as many mistakes as I have. 你犯的错误和我犯的一样多。
I haven’t got as much money as I thought. 我不像原来想像的有那么多钱。
其间接形容词时,有时该形容词还可修饰另一名词,但这个名词应带有不定冠词(注意词序)。如:
She is as good a teacher as her mother. 她和她妈妈一样是位好老师。
也可说。如:She is a teacher as good as her mother.
但不说。如:She is as a good teacher as her mother. / They are as good teachers as us.
(3) 第二个as后接从句时,该as通常为连词,但有时这个as还充当其后从句的主语或宾语,此时该as实为关系代词。如:
I gave him as much as he could eat. 他能吃多少,我就给了他多少。
We’ve got food for as many people as want it. 我们的食物,无论多少人吃都够了。
(4) 该结构根据情况可用使用以下修饰语。如:(not) nearly, almost, just, nothing like, exactly, not quite, half, one-ten, twice, three times, 30 per cent等,并且这些修饰语必须置于第一个as之前,而不能置于其后。如:
He doesn’t play half as well as his sister. 他演奏的水平不及他姐姐的一半。
This dress is twice as expensive as that. 这件连衣裙比那件贵一倍。
(5) 若第二个as引导一个表示将来意义的从句,则该从句可用现在时表示将来,也可直接使用将来时态。如:
We’ll get there as soon as you do [will]. 你一到,我们就到。
(6) 在非正式场合(尤其是美国英语中),有时可以省略第一个as。如:
When over forty, he married a woman poor as himself. 他在40多岁时娶了一个像他本人一样穷的女人。
另外,若意思明确,有时可省略第二个as及其后的相关词语。如:
The radios in that shop will be cheaper, but not as good. 那家商店的收音机会便宜些,但质量没那么好。

关键词:双代号网络图,虚箭线,画法
1 虚箭线运用的几种常用情况
(1) 网络计划中涉及交替工序, 交替工序的画法如图1所示。
(2) 两个工序有共同的起始点事件和终点事件, 如图2 (1) 所示, 此时需要添加虚箭线, 如图2 (2) 所示。
(3) 某两个工序除了有共同的紧后工序外, 这两个工序还有其他紧后工序, 这是虚箭线运用过程中的重点与难点所在。本文予以重点分析。
1) 两个工序除具有共同的紧后工序以外, 其中一个还有其他紧后工序, 此时用到一条虚箭线, 如图3所示, A、B有共同的紧后工序D, 除此之外, A还有其他紧后工序C, 此时, 运用一条虚箭线即可清晰表明工序间的逻辑关系。
2) 两个工序除具有共同的紧后工序以外, 还各自都有其他紧后工序, 此时用到两条虚箭线, 如图4所示, A、C有共同的紧后工序D, 除此之外, A还有其他紧后工序B, C还有其他紧后工序E, 此时会用到两条虚箭线。
2 实例分析
例如, 已知如表3所示资料, 要求绘制网络图 (本例选自清华大学出版社, 胡运权主编的《运筹学习题集》P104) 。
第1步, 从表3中找出具有共同紧后工序的工序。
有共同紧后工序的工序包括以下几对:g、m;a、e;b、c;a、l;f、i。
第2步, 从找出的工序中再筛选出除了具有共同紧后工序以外, 还有其他紧后工序的工序, 并将其单独绘制成网络图。
在列出的有共同紧后工序的工序中, a、e工序组合中, a还有其他紧后工序i;b、c工序组合中, c还有其他紧后工序e和m;a、l工序组合中;a有其他紧后工序f, l有其他紧后工序d, 分别绘制成网络图, 如图5~图7所示。
第3步, 按表1中要求逐步画出网络图的每一部分, 将第2步中绘制好的图形补充到现有的图中, 并重新填写事件序号, 注意箭头事件序号要大于箭尾事件序号。如图8所示, 图5~图7所对应的虚箭线在图8中做了标注。

9.简历的几种常见问题 篇九
1.格式落伍的简历――简历的形式上不符合市场通用的模式。如有的简历采用表格形式,表格简历国有企业中用得多,但一般企业的hr看了都会不习惯,觉得格式上比较落后。
2.内容描述不正确的简历――简历的内容描述不符合市场规律。如某国有银行的人想应聘外资银行或其他金融企业的职位,但在职位描述上都用老国企的说法,如某某岗,某营业主任等。
3.简历内容过于冗长――如有的简历扬扬洒洒,短短几个月的经历,简历内容竟多大三页,真是“裹脚布,又长又臭”。
4.简历内容极其简单――有的简历内容非常少,在工作经历内容上只有关于公司和职位,没有关于具体工作职责的描述,别人看了后都不知道你在公司具体做什么的。
5.传记式的简历――这种简历,就像自我介绍一样,简历的内容没有分类,都堆在一起,没有层次和逻辑机构。
6.内容分类不完整――内容的分类不够精练、缺乏层次性。简历分类一般应分个人资料,自我评价,求职目标,教育背景,工作经历,相关技能等。工作经历的内容应从最近的职位经历开始写。
7.没有重点的简历――简历应该是根据不同目标职位来制作,在工作经历描述应突出与目标职位类似经历的描述,而应把以往的与目标职位不相关的经历描述上应简洁一些。在技能和培训经历描述上,应该写与目标职位相关的内容。
10.作文的开头的几种常见方式 篇十
2010-6-18 11:47:00作者:佚名来源:转载查看评论(0条)字号:大 中 小
古人说“凤头豹尾”,就是说开头要写得有姿有彩,像凤凰的头那样,有人说:“好的开头等于成功的一半”,这些都说明了开头的重要。同样,好的开头,对于中考作文来说,也具有重要意义。那么,什么样的开头是好的呢?文无定法,开头无固定的格式,衡量好坏的标准只有一个,那就是看它是不是文章的有机组成部分,能否为文章的内容和中心服务,能否吸引读者读下去。
由于时间与篇幅的限制,考场作文的开头讲究简洁、生动、优美,可考虑选用如 下开头方法。
1、开门见山式所谓“开门见山”,是一种比喻的说法,指的是写文章时直截了当入题的一种写法。如《谈骨气》一开头就亮出观点:“我们中国人是有骨气的。”《白杨礼赞》一开头就触及题旨:“白杨树实在是不平凡的,我赞美白杨树!”这种方法在各类文章的写作中得到广泛的运用,占有很大的比例。它的表达角度,可以是开头直叙本事,也可以起笔点题;可以开宗明义揭示主旨,也可以单刀直入点明敌论。如此等等。由于这种写法干脆利落,入题快捷,不枝不蔓,所以应为考场作文开头的首选方法。
2、背景渐入式自然科学告诉我们宇宙是一个大系统,社会科学告诉我们,人类社会又是一个大系统。一棵树是在一座森林的系统之内,一片叶又属于这棵树的系统。一个人属于社会这个系统,一根指头又属于这个人的系统。因此,任何单个事物,任何一种现象都离不开它所属的系统,即它赖以生存的社会背景或自然背景。如《孔己已》开头:“当街一个曲尺形的大柜台……可以随时温酒”。《在烈日和暴雨下》开头:“六月十五那天,天热得发了狂!”这些开头或交待事情发生的时间、地点、节令、气候或阐述论题的背景、环境等。在考场作文时,有些题目乍一看,觉得突兀,不可捉摸,但联系背景一想,便豁然开朗了。如1999年的高考作文题目是《假如记忆可以移植》,联系近几年的科技发展,克隆技术的问世了,基因可以移植了,航天技术更是突飞猛进。近几年来,我国的经济持续发展,经济建设取得了突出成就。联系这些背景,文章的内容可写了,联想与想象也便有了立足点了。
3、设问置疑式先倒叙事情的结果,设置悬念,或先设问破题,引起说明或议论。如《枣核》的开头:“动身访美之前,……可是却很蹊跷。”又如《万紫千红的花》开头设问:“花为什么会有各种美丽鲜艳的色彩呢?”这种开头方法,其目的是设置悬念,引起读者的关注,激发读者的兴趣,同时增加文章的曲折,显现文章的布局之美。这种开头技法在中考作文中的频率很高。当然,这种开头形式要注意巧妙运用,避免单
一、或追求形式上的好奇。(其实,这种开头的形式是很丰富的,如:①先提出一个悬而未决的问题。②先截取一个精彩的事件片断。③先交待一个起线索作用的物件。④先安排一个引发故事的场景。⑤先介绍与故事情节紧密相关的人物。
4、名言警句式开头引用警句、名言、诗句或俗语、谚语等,可以达到吸引读者,帮助突出中心的作用。如《回声》开头引用了艾青的一首诗。《怀疑与学问》开头引用了程颐的话:“学者先要会疑”等。这种开头法,也是一般考生容易掌握和便于使用的方法。试想,哪个考生记不得几首古诗,几句格言,几条名言呢?考场作文,因题而异,相机引用,又何乐而不为?名言警句式开头运用得自如,往往能增强开端的气势,使人感到突兀、峥嵘、高远。当然,引用时要尽量准确,避免出现知识性错误。
5、精辟设喻式开头设喻,以引起读者对要说明的事物或道理的兴趣。如《中国石拱桥》开头:“ 石拱桥的桥洞成弧形,就像虹。”《马说》开头:“世有伯乐,然后有千里马。”以伯乐与千里马的故事为喻引出中心论
