名詞性從句

核心解讀五  同位語從句
1.同位語從句語序為陳述語序，多放在下列詞的后面，如：idea, fact, news, hope, wish, promise, doubt, suggestion, truth, question, problem, belief, probability ….對其名詞起進一步說明作用，是名詞的具體內容。
例14
i have no idea _____ far the airport is from here.
a. what        b. how        c. it’s       d. that
[key]  b
例15
there’s a feeling in me _____ we’ll never know what a ufo is not ever.
a. that        b. which        c. of which        d. what
[key]  a
[點撥] that引導的同位語從句修飾feeling
2.that引導同位語從句與定語從句的區別
that引導同位語從句時，在從句中不充當任何成分，只起連接作用，但不可省略，而that在定語從句中可做主語、賓語和表語。作賓語時可省略。
the news that he passed the exam was a great surprise.（同位語從句）
the news (that) he told me was a great surprise.（賓語從句）
核心解讀六  名詞性從句中的幾類問題特別提示
1、當疑問詞做主語或主語的定語時的語序不變。
 all of us asked her what was the matter/wrong/ the trouble with her face. (做主語)
tom asked me whose pen was red. (whose 做主語的定語)
2、賓語從句中的插入語常見形式
 1）特殊疑問詞+do you think (believe, suppose, say…)
who do you think is the best student in our class?
who do you think can answer the question?
what do you suppose happen to her?
what time do you think tom will come here?
2）插入語還有you think/ expect等
   give it to whoever you think can do the work well.
3、連接詞的對稱
it took the teacher a few days to remember who was who in the class.
4、that可以作except, in, besides, but的賓語，不可充當其它介詞的賓語,in that 意為“在于（因為）” but that 意為“要不是（只是）”except that 意為“除了”
the suit fitted him well except that the color is a little brighter.
其它介詞后面需要用that從句作賓語，必須用it 作形式賓語。
you may depend on it that i will always help them.
5、賓語從句中的否定轉移
主語是第一人稱i / we 。
1) 將think, believe, suppose, expect, fancy, imagine, consider, expect, guess, reckon等動詞后面賓語從句的否定詞轉移到主句中，即主句的謂語動詞用否定式，而從句的謂語動詞用肯定式。
　 i don't think i know you.　我想我并不認識你。
　 i don' t believe he will come.　我相信他不回來。
注意：若謂語動詞為hope,賓語從句中的否定詞不能轉移。
　 i hope you weren't ill. 我想你沒有生病吧。
2) 如果think, believe, suppose, expect, fancy, imagine, consider, expect, guess, reckon等動詞前有副詞或表示強調的do, does, did或同其它詞構成并列謂語，或不以現在時出現，或用在插入語中，這時候不用否定轉移。
