[句式解读]　句中s that引导目的状语从句，从句中含有情态动词culd。[用法总结](1)s that引导目的状语从句，意为“以便，为了”，可用in rder that 替换，从句中常有may，can，culd等情态动词。
①I will leave s that yu can cncentrate n yur wrk.我这就走，以便让你专心工作。②He came in quietly s that he wuldn’t wake his wife up.他轻轻地进来，为了不把他的妻子吵醒。(2)s that引导结果状语从句，意为“因此，所以”，通常不与情态动词连用，从句前可用逗号与主句隔开。③I gt up early, s that I caught the first bus.我起得很早，所以赶上了第一班公共汽车。④Suddenly it began t rain heavily，s that it was almst impssible t carry n driving.突然下起了大雨，几乎无法继续开车。
[名师提醒]　in rder that也可以引导目的状语从句，常与s that互换，s that一般不用于句首，而in rder that可用于句首。

2.T take a bicycle, yu had t put in a special card.(教材P37)要骑自行车，你必须放入一张特别的卡。
[句式解读]　句中t take a bicycle为不定式短语作目的状语。[用法总结]动词不定式作目的状语通常译为“为了……”，主要有以下三种结构形式：
①They wrked hard t get gd marks in the final exams.为了在期终考试中得到好分数，他们很用功。②They tk exercise every day t keep healthy.他们为了保持健康每天运动。③In rder t learn spken English well, he ften talks with American friends.为了学好口语他常常和美国朋友交谈。④Lily saw many Chinese films s as t knw mre abut China.莉莉看了很多中国电影以便更多地了解中国。

in rder t discuss
s as t discuss
T/In rder t discuss
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：
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。
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。
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。
