Comment:
你第一題, 第五題和第六題錯
1. You have (a) new dress. Where Did you buy it?
I bought (the) dress from Sog last week
5. I bought (a) coat and (a) pair of trousers yesterday.
(The) coat cost 100 dollars and (the) trousers cost 80 dollars
6. I watched (a) movie yesterday.
What was (the) movie about?

When something is first mentioned, the noun usually has a/an. When the same thing is mentioned again, the writer uses the. In #6, use “a” in the first sentence, and use ”the” in the second sentence.

B.
Mrs. Wong : I want to buy (a) duck
Hawker : Which one do you want?
Mrs. Wong : Give me (the) one with big eyes. How much is it?
Hawker : It is 40 dollars the pound so this one is 90 dollars
Mrs. Wong : Ok. Do you know how to cook ducks?
Hawker : Put it in (an) oven for (an) hour. You can eat (the) duck today or store it in (a) fridge for three days.

Comment:
You can eat (the) duck today ("duck" in this sentence refers to "it" in the first sentence. ~ it 是 duck.)

I beg to differ from 回答者: Jenkin
Hawker : Put it in (AN) oven for (an) hour. You can eat (THE) duck today or store it in (A) fridge for three days.
家中必定有一件的東西或人, 未必使用 the, 問題是第一次提到東西或人, 常用 “a/an”, 再提到才用 the.
例如:
She has a son. The son was born and raised in America.
I have a bicycle at home. The bicycle was given by my sister as a birthday present.

同時, 在 manual, 給 instruction 中, 多數用 a/an
Put it in an oven for an hour, instruction 是意味任何一個 oven 都得, 不是某個 oven. We use “the” for subsequent references.

yES, IS "watched"

A.
5.I bought (the) coat and the pair of trouses yesterday. [這句理應是用a coat和 a pair of trousers，但如果後面trousers已用了the pair…則表示句子(或前文)已經指出那物件，所以這裏才用the，因此一致地用the coat應該是對的；否則一般情況應該是a的。
6. I wanted (a) movie yesterday. [這句的動詞是否應該是watched?]用a是因為內容沒有講出那一套電影，意思只是告訴人我看了一齣影片，不是交代某一指定的片子。所以才會接著問「你所講那一」(the) movie是關於甚麼。]
What was (the) movie about? B.Mrs Wong : Ok. Do you know how to cook ducks?
Hawker : Put it in (the) oven for (an) hour. You can eat (a) duck today or store it in (the) fridge for three days. [an oven是文法上正確-但由於oven和fridge都是一件很確定的東西(假設家中必定有一件的)，所以實際講法時會用the才算正確的英文用法-加上這句是指示「教你如何...」當中句子都會必定用the一件工具或東西。]
