Which is bigger, the sun or the earth? 太陽(yáng)和地球哪個(gè)大?
What writers do you like? 你喜歡哪些作家?
注意,以上區(qū)別只是一般原則,并不絕對(duì)。如也可說:
Which writers do you like? 你喜歡哪些作家?
Which [What] will it be—tea or coffee? 這會(huì)是什么──茶還是咖啡?
2. which, what, who 均可用作代詞(即其后不跟名詞)。關(guān)于 which 和 what的和法區(qū)別跟上面的分析相似。這里只談?wù)?who 的用法:who 一般只用來指人,不管選擇范圍大還是小,明確還是不明確均可用(當(dāng)選擇范圍比較明確且用作賓語(yǔ)時(shí) who 也可用或 which 或 which one 代之)。如:
Who won—Tom or Mike? 誰(shuí)贏了─湯姆還是邁克?
Who is your favourite poet? 你最喜歡的詩(shī)人是誰(shuí)?
Who [Which, Which one] do you like best—your father or your mother?你更喜歡誰(shuí)──父親還母親?
3. 正由于 what 和 who 的選擇范圍可以很大或不明確,所以其后可以跟else,但一般不跟表示特定范圍的 of 短語(yǔ);which 的選擇范圍相對(duì)比較小或明確,所以其后一般不接else,但卻常 of 與短語(yǔ)連用。如:
Who [What] else did you see there? 你在那兒還看到了別人的什么人 什么東西?
Which of the three girls is the oldest? 這三個(gè)女孩中哪個(gè)年紀(jì)最大?
不過,以上說的也是一般情況,有時(shí)也有例外,如有時(shí)也說:
Who of you three first thought of this? 你 們?nèi)酥姓l(shuí)最先想到這一點(diǎn)?
