7、answers Step2. Grammar ★ 關(guān)系代詞與關(guān)系副詞辨析 定語(yǔ)從句的考查主要集中在引導(dǎo)詞的確定上。準(zhǔn)確判斷引導(dǎo)詞在定語(yǔ)從句中所作的成分是選擇引導(dǎo)詞的關(guān)鍵。關(guān)系代詞that, which, who, whom在從句中作主語(yǔ)和賓語(yǔ)，作賓語(yǔ)時(shí)可省略；關(guān)系副詞where, when, why在從句中作狀語(yǔ)；whose在定語(yǔ)從句中作定語(yǔ)，起限定作用。 下面，請(qǐng)大家用適當(dāng)?shù)囊龑?dǎo)詞填空，完成下列句子。 1.

13、句之間往往用逗號(hào)分開(kāi)。注意：關(guān)系代詞that不能引導(dǎo)非限制性定語(yǔ)從句；在非限制性定語(yǔ)從句中即使關(guān)系代詞which, whom在從句中作賓語(yǔ)，也不能省略。 下面，請(qǐng)大家把下列句子譯成漢語(yǔ)，并分析、比較其意義的不同。 1.

16、hich都可以指代整個(gè)主句或主句的一部分，引導(dǎo)非限制性定語(yǔ)從句，并且在定語(yǔ)從句中作主語(yǔ)或賓語(yǔ)。其中，as引導(dǎo)的非限制性定語(yǔ)從句位置較靈活，可以位于主句前、中或后，而which引導(dǎo)的定語(yǔ)從句只能放在主句后。 下面，請(qǐng)大家根據(jù)括號(hào)內(nèi)的漢語(yǔ)提示，用定語(yǔ)從句完成下列句子。 1.
