| 释义 | 〔that〕The standard rule isthatthat should be used only to introduce a restrictive (or "defining") relative clause, which serves to identify the entity being talked about;in this useit should never be preceded by a comma.Thus, we sayThe house that Jack built has been torn down, where the clausethat Jack built tells which house was torn down, orI am looking for a book that is easy to read, wherethat is easy to read tells what kind of book is desired. Onlywhich is to be used with nonrestrictive (or "nondefining") clauses, which give additional information about an entity that has already been identified in the context;in this use,which is always preceded by a comma. Thus, we sayThe students in Chemistry 10 have been complaining about the textbook, which (not that ) is hard to follow. The clausewhich is hard to follow does not indicate which text is being complained about; even if it were omitted,we would know that the phrasethe textbook refers to the text in Chemistry 10. The use ofthat in nonrestrictive clauses like this, though once common in writing and still frequent in speech,is best avoided in formal style. ·Some grammarians have argued that symmetry requires thatwhich should be used only in nonrestrictive clauses, asthat is to be used only in restrictive clauses. Thus, they suggest that we should avoid sentences such asI need a book which will tell me all about city gardening, where the clausewhich will tell me all about city gardening indicates which sort of book is needed. Such use ofwhich is useful where two or more relative clauses are joined by and or or, as inIt is a philosophy in which the common man may find solace and which many have found reason to praise. Which is also preferred to introduce a restrictive relative clausewhen the preceding phrase itself contains athat, as inI can only give you that which I don't need (not that that I don't need ) or We want to assign only that book which will be most helpful (preferred tothat book that will be most helpful ). · That may be omitted in a relative clause when the subject of the clause is different from the referent of the phrase preceding the clause. Thus, we may say eitherthe book that I was reading or the book I was reading, where the subject of the clause (I ) is not the referent of the phrase the book. Omission ofthat in these cases has sometimes been described as incorrect, but the practice is extremely common and has ample precedent in reputable writing. ·There have also been occasional objections to the omission ofthat in its use to introduce a subordinate clause, as inI think we should try again. But this usage is entirely idiomatic and is in fact favored with some of the verb phrases that can introduce such clauses:thus, one would more normally write 标准规则中，that 应只被用于引导限定性（或“确定的”）关系从句， 这些从句用于明确正被谈论的实体；在这种情况下，前面决不能有逗号。因此，我们说杰克建的房子已经拆毁了 ， 在这里，从句杰克所建的 指明哪幢房子被拆毁了， 或者我正在找一本易读的书 ， 在这里，易读的 指明哪类书是需要的。 只有which 用于非限定性（或“不确定的”）从句中， 为已经在上下文中定义的实体提供附加信息；在此用法中，which 之前总有逗号。 因此，我们说化学10班的学生一直在抱怨这课本，实在 （不是 that ) 是太难懂了 。 从句which is hard to follow 并不指明哪一课本被抱怨； 即使它被省略，我们也知道the textbook 指化学10班的课本。 That 象这样用于非限定性从句中， 虽然在写作中曾很普遍而且在口语中依然频繁出现，但在正式文体中最好避免使用。一些语法学家认为对称性要求which 应只用于非限定性从句中， 就象that 只用于限定性从句中。 因此，他们建议我们应该避免诸如我需要一本关于城市园艺的书 这样的句子， 这里从句which will tell me all about city gardening 指明需要何种书。 当两个或多个关系从句被and 或 or 连接时， which 的这种用法很有用， 如是哲学使普通人找到慰藉并使许多人有理由去称颂。 Which 也用作引导限定性关系从句，在当前置短语中含有that 时， 如我只能给你我不需要的东西 （不是 that that I don't need )或 我们只想分发那本最用的书 （好于that book that will be most helpful )。 当从句主语与从句前短语所指不一致时，that 在关系从句中可以省略。 因此，我们可以说the book that I was reading 或者 the book I was reading 。 在这里，从句主语(I )和短语 the book 的主语不同。 在这些情况下，that 的省略有时被认为是错误的， 但是这在实际中极普遍而且在规范写作中有充分的先例。对于that 用于引导从句时被省略偶然持有异议， 如在我认为我们应该再试一次 中。 但这种用法完全符合语法而且实际上有一些引导这样从句的短语支持；因此，可以正常应用 〔speller〕An elementary textbook containing exercises that teach spelling.单词拼写课本：含有拼字练习的基础教科书〔intelligent〕The most intelligent students do additional reading to supplement the material in the textbook.最聪明的学生用增加阅读量来补充课本的内容。〔earwig〕In an Anglo-Norman text written around the beginning of the 15th century we are told that elephants guard their ears diligently against flies and earwigs.Elephants have good cause to protect themselves against these insects if, as folklore has it, earwigs go through the ear into the head.The earwig, however, prefers to dine on things such as flowers, fruit, and small insectsrather than brain tissue.Folklore is responsible, though, for the insect's name,which was formed in Old English fromēare, the Old English source of our word ear, and wicga, "insect,” a word presumably related to our word wiggle. 大约在15世纪初期，有一本盎格鲁·诺曼的课本提到大象很小心地保护它们的耳朵，以防苍蝇和蠼螋。民间传说讲，蠼螋会通过耳朵进入大脑，大象防范这些昆虫是很有理由的。但是蠼螋喜欢吃花朵、水果及一些小昆虫，而不是大脑组织。然而民间传说却产生了这种昆虫的名字，当时是由古英语词eare ，即我们的 ear 的古英语词源及可能和现代词 wiggle 有关的意为“昆虫”的 wicga 组成的 〔diabetes〕Diabetes is named for one of its distressing symptoms.The disease was known to the Greeks asdiabētēs, a word derived from the verbdiabainein, made up of the prefixdia-, "across, apart,” and the word bainein, "to walk, stand.” The verbdiabeinein meant "to stride, walk, or stand with legs asunder"; hence, its derivativediabētēs meant "one that straddles,” or specifically "a compass, siphon.”The sense "siphon" gave rise to the use ofdiabētēs as the name for a disease involving the discharge of excessive amounts of urine. Diabetes is first recorded in English, in the formdiabete, in a medical text written around 1425. 糖尿病因其痛苦的症状之一而得名。此病症闻名于希腊语diabetes ， 是动词diabainein 派生出的单词， 由前缀dia- “穿过，隔开”和单词 bainein “走，站”构成。 动词diabeinein 表示“跨过，走过或两条腿分开站着”； 因此，其派生词diabetes 表示“一个人叉腿站着”， 或专指“指南针，虹吸管”。在diabetes 使用“虹吸管”是表示排尿量过多的一种病的名称。 Diabaets 一词第一次被记录到英文中是在1425年前后的一本医学课本中，以diabete 的形式出现 〔devotion〕devotions Prayers or religious texts: devotions 祈祷文或宗教课本：〔update〕update a textbook; update the files.更新课本；更新档案〔Webster〕American lexicographer whoseSpelling Book (1783) helped standardize American spelling. His major work, An American Dictionary of the English Language, was originally published in 1828. 韦伯斯特，挪亚：(1758-1843) 美国词典编撰者，他的《美国拼音课本》 有助于美式拼写标准化。他的主要作品 《美式英语大词典》 最早出版于1828年 〔interpolate〕To change or falsify (a text) by introducing new or incorrect material.篡改：通过插入新的或不正当的材料改变或伪造（课本）〔interpolate〕To insert (material) into a text.在课本中添加（材料）〔interlinear〕Inserted between the lines of a text.书写于行间的：在课本的行间插入的〔textbook〕A book used in schools or colleges for the formal study of a subject.课本：用于学校或学院某科目正式学习的书 |
