VOA一分鐘英語(yǔ)：怎樣區(qū)分 what 和 which？

英語(yǔ)疑問(wèn)詞 “what” 和 “which” 用來(lái)引導(dǎo)問(wèn)句，但由它們引導(dǎo)的問(wèn)句之間有一個(gè)根本的區(qū)別。哪一個(gè)詞用來(lái)引導(dǎo)有選擇的疑問(wèn)句？哪一個(gè)詞引導(dǎo)的問(wèn)句，其答案不受任何限制？
 
文字稿
Hello again, everyone. Tom here for BBC Learning English. Today, I'm going to explain the difference between what and which in questions.
What is used to ask a question which has a lot of possible answers. Consider the question: What do you want to eat for lunch? Here, there are no choices to limit your reply. You could choose anything you want.
We use which when we have options to choose from. So, here we have two choices – a sandwich and a melon. So I can say: Which do you want to eat? The sandwich or the melon?
Now, next time you need to ask a question, you'll know which word to use. What for anything and which when you have a choice.
 
用法總結(jié)
怎樣區(qū)分 what 和 which?
1 What is used to ask a question which has a lot of possible answers.
用 “what” 引導(dǎo)的疑問(wèn)句的回答沒(méi)有限制，有很多種可能。What do you want to eat for lunch?
Here, there are no choices to limit your reply. You could choose anything you want.
這個(gè)問(wèn)題的回答沒(méi)有限制，可以根據(jù)自己的喜好作答。
 
2 We use which when we have options to choose from.
當(dāng)提問(wèn)有選擇時(shí)，用 “which” 引導(dǎo)疑問(wèn)句。
So, here we have two choices – a sandwich and a melon. So I can say:
比如：我有兩個(gè)選擇，選擇一：三明治，選擇二：瓜 。這時(shí)就可以問(wèn)：
Which do you want to eat? The sandwich or the melon?
