Ⅱ.根据提示完成课堂小作文


李先生被邀请到森林里去野餐。但是当他到达目的地 (destinatin) 的时候，他发现没有停车 (parking) 场，因此(therefre) 他不得不把自行车停在路 (path) 边。不幸的是，当他野餐结束之后，他发现他的自行车不见 (disappear) 了。为了防止这种情况再次发生，他想出 (cme up with) 了一个解决办法 (slutin) ——设计一个跟踪 (tracking) 系统。从那以后，他的自行车再也没有被偷过。


,__he__fund__that__there__was__nt__a__parking__lt.Therefre,__he__had__t__park__his__bike__by__the__side__f__the__path.Unfrtunately,__when__he__finished__the__picnic,__he__fund__that__his__bike__disappeared.T__prevent__this__frm__happening__again,__he__came__up__with__a__slutin—designing__a__tracking__system.Since__then,__his__bike__has__never__been__stlen__again.


名词用作动词








一、在英文中，有许多“名词活用作动词”的现象。或者说，这些单词本身就有动词的意思，只是我们在学习这些单词的时候通常只接触了其名词的意思。


举个最简单的例子“man”这个单词，我们都知道是人、男人的意思，但它也可以作动词，有操作、配置人员、使增强勇气、拿出男子气概等意思。


Yu need t man up and wn up t yur mistake.


你要像个男人一样承认自己的错误。


二、熟练掌握这种名词和动词之间的转换具有非常重要的意义，对于我们英语水平的提高也至关重要。它的主要作用体现在：


1．让语言更加简洁


比如说表示“我坐公共汽车去上班”这个意思，你可以说“I take a bus t wrk”也可以说“I bus t wrk”。


当bus作动词时既包含了乘坐这个动作，又包含了所乘坐的交通工具，所以可以帮助省略不必要的take，让说话写作更加简洁明了。


2．使语言更加生动


比如crner这个单词，名词意思是角落、墙角，动词的意思则有转弯、垄断、使为难等等。


With this new technlgy, we are ging t crner the market within the next tw years.有了这项新科技，我们将在未来两年垄断市场。


当crner这个单词作垄断意思解释的时候非常形象，想象一下一家公司把所有竞争者都逼到了墙角，这不就是垄断吗？


还有个单词entrance，名词解释是入口，但当它作动词时就变成了使着迷、欣喜若狂。想象一下某个事物可以进入你的心灵，让你为之心动。


Her beauty entrances him.她的美丽让他痴迷。


所以如果能做到名词的动词活用，可以使英文的语句更加具有画面感。


3．使语言更加地道


比如我们要用英文表达“他著有两本畅销小说”。


你当然可以说“He has written tw best－selling nvels”，但这里的write让人感觉只是“写”，而没有“著”，所以会显得不够书面，不够地道。


如果用authred来取代written就可以准确地表达出句子。


英文单词中名词作动词的情形远远不止以上的例子。比如还有一组植物的名词，像花flwer、杂草weed、植物plant、种子seed、根rt等等都可以作动词使用，分别是成熟、除草、种植、播种、固定的意思。


随着人类社会的不断前进，语言也不断地向前发展，旧词少用，新词产生，语言变得越来越生动、形象，富于表现力和丰富多彩。人们常常用转化法、合成法、派生法等来创造新词。


所谓转化法，就是词类转化，或叫词性转化，即利用某些词本身固有的特点，把原属于一类词性的词转化成另一种词类，即一种词类不经过任何词态变化而有意地作另一类词使用，同时又没有失去原有词内在的意思。

【语篇解读】 究竟什么是幸福？作者给出了自己的理解——幸福意味着善良、爱心和无私。


1．exact [修饰名词definitin，应用形容词。]


2．a [此处泛指“一所小房子”，用不定冠词a。]


3．died [根据years ag可知，应用一般过去时。]


4．living [v.－ing作定语修饰several children。]


5．stries [stry“故事”是可数名词，讲的故事不止一个，故用复数形式。]


6．but/yet [由unlucky及happy的对比可知，前后句之间为转折关系，故用but/yet连接。]


7．nisily [修饰动词talk用副词。]


8．t enjy [此处用动词不定式作目的状语。]


9．It [指代前一句提到的happiness，故用It。]


10．bringing [所用词在宾语从句中作主语，且指抽象性动作，故应用动名词形式。]
