這里回答仍用a：There's (a) clean cup in the cupboard.因?yàn)榇鹁鋸?qiáng)調(diào)的是：廚里有個(gè)（一個(gè)）干凈的杯子.是強(qiáng)調(diào)數(shù)量：有一個(gè)；而不是描述那個(gè)（the cup）杯子.跟一般的第二次提到用the的用法有區(qū)別.

希望對(duì)你有幫助那這里There's (a)可以換成There's (the)嗎？Friend:Is there (an) electric cooker in your kitchen?You:Yes,there is.There's ()[填a還是the呢？？怎么判斷？？]electric cooker in our kitchen.It's in (the) middle of (the) room.

不可以，理由前面已經(jīng)講了：這里是強(qiáng)調(diào)數(shù)量：一個(gè)，而不是特指：那個(gè)

Friend:Is there (an) electric cooker in your kitchen?
You:Yes,there is.There's (one). 這里一般填one，作代詞：是的，有一個(gè)（電爐子）。

這里的答句一般會(huì)是以下兩種情況：

1. Yes, there is. There's (one).

2. Yes, there is. (The) electric cooker is in our kitchen. It's in (the) middle of (the) room.

(The) electric cooker 【少動(dòng)詞了：is】 in our kitchen.It's in (the) middle of (the) room.后面兩格都用the

或者：(The) electric cooker in our kitchen is in (the) middle of (the) room.

希望對(duì)你有啟發(fā)，如對(duì)你有幫助，請(qǐng)記得及時(shí)采納
