that的用法：
標(biāo)準(zhǔn)規(guī)則中,that 應(yīng)只被用于引導(dǎo)限定性（或“確定的”）關(guān)系從句, 這些從句用于明確正被談?wù)摰膶?shí)體；在這種情況下,前面決不能有逗號(hào).因此,我們說杰克建的房子已經(jīng)拆毀了 , 在這里,從句杰克所建的 指明哪幢房子被拆毀了, 或者我正在找一本易讀的書 , 在這里,易讀的 指明哪類書是需要的. 只有which 用于非限定性（或“不確定的”）從句中, 為已經(jīng)在上下文中定義的實(shí)體提供附加信息；在此用法中,which 之前總有逗號(hào). 因此,我們說化學(xué)10班的學(xué)生一直在抱怨這課本,實(shí)在 （不是 that ) 是太難懂了 . 從句which is hard to follow 并不指明哪一課本被抱怨； 即使它被省略,我們也知道the textbook 指化學(xué)10班的課本. That 象這樣用于非限定性從句中, 雖然在寫作中曾很普遍而且在口語中依然頻繁出現(xiàn),但在正式文體中最好避免使用.一些語法學(xué)家認(rèn)為對(duì)稱性要求 which 應(yīng)只用于非限定性從句中, 就象that 只用于限定性從句中. 因此,他們建議我們應(yīng)該避免諸如我需要一本關(guān)于城市園藝的書 這樣的句子, 這里從句which will tell me all about city gardening 指明需要何種書. 當(dāng)兩個(gè)或多個(gè)關(guān)系從句被and 或 or 連接時(shí), which 的這種用法很有用, 如是哲學(xué)使普通人找到慰藉并使許多人有理由去稱頌. Which 也用作引導(dǎo)限定性關(guān)系從句,在當(dāng)前置短語中含有that 時(shí), 如我只能給你我不需要的東西 （不是 that that I don't need )或 我們只想分發(fā)那本最用的書 （好于that book that will be most helpful ). 當(dāng)從句主語與從句前短語所指不一致時(shí), that 在關(guān)系從句中可以省略. 因此,我們可以說the book that I was reading 或者 the book I was reading . 在這里,從句主語(I )和短語 the book 的主語不同. 在這些情況下,that 的省略有時(shí)被認(rèn)為是錯(cuò)誤的, 但是這在實(shí)際中極普遍而且在規(guī)范寫作中有充分的先例.對(duì)于that 用于引導(dǎo)從句時(shí)被省略偶然持有異議, 如在我認(rèn)為我們應(yīng)該再試一次 中. 但這種用法完全符合語法而且實(shí)際上有一些引導(dǎo)這樣從句的短語支持；因此,可以正常應(yīng)用
用法與例句：
I take it she has passed the test
我猜她通過了測驗(yàn),
27. than I take it that she has passed the test. Thatshould not be omitted, however, when the subordinate clause begins with an adverbial phrase or any element other than the subject:
好于I take it that she has passed the test. 然而,當(dāng)從句以副詞短語開頭或其它不是主語的成份開頭時(shí),that不能省略：
用法與例句：
She said that under no circumstances would she allow us to skip the meeting.
她說怎么樣都會(huì)讓我們參加會(huì)議.
用法與例句：
The book argues that eventually the housing supply will increase.
書中證實(shí)住宅供應(yīng)最終會(huì)增加.
28. This last sentence would be ambiguous if that were omitted, since the adverb eventually could then be construed as modifying either argues or will increase. See Usage Note at doubt, this, whatever, which, who
最后一句話中如果that 被省略,句子將變得模棱而可, 因?yàn)楦痹~eventually 可以被解釋為修飾 argues or will increase 參見 doubt, this, whatever, which, who.
