The reason is ________it can very quickly transmit written documents. Who knows how many other inventions just need to be recognized as valuable? 【答案】because；value；was invented；electrically；useless；a/any；wires；for；equipment；that 【解析】【分析】主要讲了一些发明因为人们不能想象它们的价值而失去，列举传真机器的发明来说明这点。（1）句意：足够奇怪的是，因为人们不能想象它们的价值，所以一些发明消失了。后句表示原因，所以用because；形容词修物主代词修饰名词，their它们的，形容词修物主代词，所以后面用形容词valuable的名词value，不可数名词，故填because，value。（2）句意：传真的科技在19世纪被发明。invent发明，实义动词，主语technology是动作invent的承受者，时态是一般过去时，所以用一般过去时的被动语态，结构是was/were+动词过去分词，主语technology是不可数名词，所以用was，invent的过去分词是invented，故填was invented。（3）句意：1843年，亚历山大贝恩发明了一种电子传输文字的机器。electrical电子的，形容词，副词修饰实义动词，transmit传输，实义动词，所以用副词electrically，电子地，故填electrically。（4）句意：起初，它被认为是无用的，因为很少有人认为有必要通过电线传输文字。be considere形容词，表示被认为怎么样，固定搭配，根据后文可知传真的作用后来才被认可，所以起初被认为是无用的，use使用，实义动词，其形容词是useless，无用的；原因是很少人认为有必要，few表示否定，所以用a/any；wire，电线，可数名词，前面没有表示单数的a或者one，所以用复数wires，故填useless；a/any；wires。（5）句意：最终，这项发明的价值得以实现，并被改进为办公用途。为了办公用途才被改进，所以用for，为了，故填for。（6）句意：到了20世纪80年代，传真机已成为办公室的标准设备。equip，装备，实义动词，形容词修饰名词，standard，标准的，形容词，所以用equip的名词equipment，设备，不可数名词，故填equipment。（7）句意：原因是它能很快地传送书面文件。the reason is that...，原因是……，固定搭

NEW CONCEPT 3 的LESSON 17里面有一句话： It has been estimated that if the bridge were packed with cars, it would still only be carryin g a third of its total capacity. 不知道为什么谓语要用复数，查了资料才明白：虚拟语气中be 的虚拟只能用were. 虽然有些口语或者非正式场合会出现类似：she treats me as if i was her daughter.或者If it was fine toda y,we would go for a picnic.的句子，但是考试或者正规书面语还是用were比较好。下面有两则关于虚拟语气的补习资料。英语虚拟语气误用辨析 1.中文：我要是你，我不会那么做。（误）I shouldn't do that if I was you. （正）I shouldn't do that if I were you.（表示与现在事实相反的虚拟语气不能用was，只能用were.）

2.中文：要是我父亲现在在这里，他会告诉我该做什么。（误）If my father were here now，he will t ell me what to do. （正）If my father were here now，he woul d tell me what to do.（表示与现在事实相反的虚拟语气中，主句的助动词只能用would，might等过去时。） 3.中文：要是我知道她的电话号码，我就会给她打电话了。（误）If I knew her telephone number，I wo uld have called her. （正）If I had known her telephone number，I would have called her.（表示与过去事实相反的虚拟语气中，条件从句的动词要用过去完成时。） 4.中文：要是昨天没下雨她也许会来。（误）If it had not rained yesterday，he mig

He won’t believe it until he sees it with his own eyes. (3)在带有till或until引导的时间状语从句的主从复合句里如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。例如： The young man read till the light went out（熄灭）. Let’s wait until the rain stops.

Study hard and you will pass the exam. =If you study hard, you will pass the exam. 3. 原因状语从句 (1)原因状语从句通常由because, since, as引导。例如： He didn’t come to school because he was ill.

英语语法大全连词

英语语法大全:连词连词（Conjuction—conj.）定义用以连接句子中的单词、短语、从句，或连接句子和句子的词叫做连词。例如： and（和），but（但是），so（所以），or（或者），… that，because（因为），since（既然），… 连词的表达功能如下：（1）并列功能（“+”代表连词）（a）词+词 boys and girls（男生和女生） you and I（你和我） poor but happy（贫困的，但是快乐）（b）短语+短语 in the city and in the country.（在城市和在乡村） by bus or by train（乘公共汽车或乘火车）（c）从句+从句例：He is not very bright but he studies hard. （他并不聪敏，但是他很用功。）例：I didn't have breakfast this morning, so I am hungry now. （今天早晨我没吃早餐，所以我现在饿了。）解说表达并列功能的连词叫做并列连词（Coordinate Conjunction）。并列连词两端的词的词类必须相等。又如“词+短语/从句”或“短语+词/从句”等也都不成立。（2）从属功能请先了解什么叫做从句（Subordinate Clause.）

本身不能独立表达完整的意思而只在句子中作句子结构的一部分者叫做从句。用以连接从句使其在主句中发挥表达功能的词叫做从属连词（Subordinate Conjunction）。 as，when，since，that，who，which，what，… 例：I know that he is a very good student. （我知道他是一个很好的学生。—“that…”是名词从句作“know”的直接宾语。）例：People who use free time well are usually healthy and happy. （善于利用空闲时间的人通常都是又健康又快乐。—“who…well”是形容词从句修饰其前面的名词“People”。）例：Many people enjoy reading when they have free time. （许多人有空闲就喜爱阅读。—“when…time”是副词从句在修饰动词“enjoy”。）
