4.TheDifferenceBetweentheAttributiveClauseandtheAppositiveClause

1)、从词类上区别

同位语从句前面的名词只能是idea,fact,news,hope,belief,suggestion,proposal,word,thought,doubt,

truth,possibility,promise,order等表示抽象意义的名词。而定语从句的先行词可以是名词、代词、主句的一部分或囫囵主句。如：

Wearelookingintothequestionwhetherheisworthtrusting.（同位语从句）

Wordcamethathehadgoneabroad.据说他已经出国了。（同位语从句）

Thedoctorwhomyouarelookingforisintheroom.（定语从句，名词thedoctor作先行词）

Ourteamhaswonthegame,whichmakesusveryhappy.(定语从句，which代表前面提到的囫囵句子)

Hismotherdidallshecouldtohelphimwithhisstudy（定语从句，代词all作先行词）

2)、从性质上区别

定语从句是从句对其先行词的修饰或限制，属于形容词性从句的范畴；而同位语从句是从句对前面抽象名词的进一步说明和解释，属于名词性从句的范畴。如：Thenewsthatourteamhaswonthegame

istrue.（同位语从句，补充说明news的内容。）

Thenews(that)hetoldmeyesterdayistrue.(定语从句，that从句作定语修饰news)

ImadeapromisethatifanyonesetmefreeIwouldmakehimveryrich.(同位语从句，补充说明promise)

Themothermadeapromisethatpleasedallherchildren.（定语从句，that从句作定语修饰promise。）

3)、从引导词及其在句子中的成份上区别有些引导词如how,whether,what可以引导同位语从句，但不能引导定语从句。如:Thatquestionwhetherweneedithasnotbeenconsidered.（同位语从句）

Ihavenoideawhathashappenedtohim.（同位语从句）

引导词that引导定语从句时，在从句中普通作主语或宾语（指物时还可以用which代替），并且作宾语时常常省略。That在同位语从句中仅起衔接作用，不充当任何成份，并且不能省略，也不能用which来代替。Theorderthatwe(should)sendafewpeopletohelptheothergroupswasreceivedyesterday.

（同位语从句，是对order的详细解释，that虽不作成份，但不能省略）

Theorder(that)wereceivedyesterdaywasthatwe(should)sendafewpeopletohelptheothergroups.

（定语从句，是名词order的修饰语，that在从句中作received的宾语，可以省略）

Practice:从A、B、C、D四个选项中，选出可以填入空白处的最佳选项。

1.Alongwiththeletterwashispromise____hewouldvisitmethiscomingChristmas.

A.thatB.whatC.whichD.whether

9.Thereason____heislateis____therewasabreakdownontherailway.

A.why;whyB.why;thatC.because;thatD.that;because

5.TheDifferenceBetweentheAttributiveClauseandtheEmphasisStructure

强调句型的句式结构为：“Itis/was+被强调部分+that/who从句”。在强调时光、地点、缘故或方式状语时，一律用that，而不用when,why或how；在强调主语和宾语时，倘若主语和宾语指代人，则可用who和whom来代替that,但是从句中的人称和数要与被强调的主语和宾语保持一致。这些都容易与定语从句混淆。定语从句和强调句型的判断主意：若将句中的“Itis/was”和“that/who”去掉，而句子不缺成分，结构残破，说明原句是强调句型；若句子结构不残破，则说明原句为定语从句。
