(九)相互代詞：表示相互關(guān)系的詞叫相互代詞。

　　each other ,one another是相互代詞,譯成“互相”,可以通用。each other表示兩者之間,而one anther表示許多人之間。它們有所有格形式each other’s ,one another’s。如： We must help each other when we are in trouble.(我們身處困境時(shí)要互相幫助。) / They sat there without talking to one another / each other.(他們坐在那兒,互相都不說話。)

　　(十)疑問代詞：用來提出問題的代詞稱為疑問代詞。

　　1.who、whom、whose、what、which、whoever、whatever、whichever主要用于特殊疑問句中,一般放在句首?？谡Z中也常用who代替whom作賓語,但在介詞后則只能用whom。如：

　　Who(m) did you invite to your birthday party?(你都邀請(qǐng)了誰參加你的生日聚會(huì)的?) / What does she want to be when she grows up?(她長大了想干什么?)

　　2.who 和whom只能獨(dú)立使用,其中who可以作句子的主語、表語或動(dòng)詞的賓語,whom只能作謂語動(dòng)詞的賓語;而what、which、whose等既可以獨(dú)立使用作主語、表語和賓語,也可以與名詞構(gòu)成疑問短語。如： Who is that man?(那男的是誰?) / What colour are their hats?(他們的帽子是什么顏色?) / Which car was made in Germany?(哪輛車是德國造的?)(被動(dòng)句)

　　注意這個(gè)提問：The man in the car is my father.(車?yán)锏哪腥耸俏腋赣H)

　　→Which man is your father?(哪個(gè)男人是你的父親?)

　　3.which除了可以詢問指代的情況之外,還可以針對(duì)說明人物的時(shí)間、地點(diǎn)、歲數(shù)、顏色、大小、狀況等進(jìn)行提問。如：People there live a very sad life.(那里的人生活凄慘) →Which people live a sad life? (哪些人生活凄慘?)/ --Which hotel have you booked for your holiday?(為了度假你預(yù)訂了哪家旅館?)―The biggest one in Haikou.(?？谧畲蟮哪羌衣灭^)

　　4.疑問代詞不分單復(fù)數(shù),視它所替代的人或事物決定單復(fù)數(shù),但是通常用單數(shù);如果修飾名詞,則以名詞的單復(fù)數(shù)為準(zhǔn)。如：Who is (are) in that playhouse?(誰在游戲房里?) / What is that? (那是什么?)/ What are those? (那些是什么?) / What colours do they have?(它們有哪些顏色?)
