20、句 定語從句 功能不同 對名詞加以補(bǔ)充說明 與先行詞是修飾與被修飾的關(guān)系，起連接作用 that 不作成分，只起連接作用，不可省略 作主語或賓語，起連接作用；并且作從句的賓語時(shí)可省略 whether/ how/ what 起連接作用，其中whether不作成分，而how和what作成分 不引導(dǎo)定語從句 其他wh-類詞 作成分；起連接作用；有自己的含義，但與先行詞無關(guān) 作成分；起連接作用；沒有自己的含義，但是代替先行詞在從句中作成分 [巧學(xué)助記]　同位語從句用法口訣 同位語從句似“定從”，兩種句式有異同； 從句均在名詞后，定“限”同“釋”要分清； 定從“t

21、hat”賓可省，同位從句“that”不省。 [名師點(diǎn)津]　同位語從句的簡易判斷方法 我們可以在名詞和從句之間加be動詞，使之構(gòu)成一個(gè)新句子，如果合乎邏輯、句子通順，則是同位語從句。 [即時(shí)演練5] 填入適當(dāng)?shù)倪B接詞并判斷下列各句是同位語從句還是定語從句 ①I have no idea when they will come to Shanghai？同位語從句 ②The information that you got yesterday is very useful. 定語從句 ③The information that you gave me yesterday is very
