Mini Quiz · 小考

Select the best answer for each question. 選出每題最適合的答案。

Question 1 / 10

A: is this? B: It's a phone.

Correct. We use Whose phone is this? to ask who owns the phone.

Use Whose to ask about ownership. "Whose phone is this?" asks who the phone belongs to.

Question 2 / 10

Whose shoes are these? Emma's shoes.

Correct. Shoes are plural (2+ items) → use They're Emma's shoes.

"Shoes" is plural → answer with They're. "It's" is only for singular items.

Question 3 / 10

Which sentence is correct? 哪個句子正確？

Correct. One watch (singular) → Whose watch is this? It's his watch.

(A) is correct. (B) uses "are" for singular — wrong. (C) "Who" asks about a person, not ownership. (D) "They're" is for plural items.

Question 4 / 10

Whose jacket is this? It's jacket.

Correct. Use the possessive her before a noun. "She" and "he" are subject pronouns, not possessives.

Use the possessive form: I → my, he → his, she → her. "She" and "he" cannot go before a noun.

Question 5 / 10

A: Whose keys are these? B:

Correct. Keys = plural → They're Ken's keys. Don't forget the apostrophe-s ('s) for names.

Keys are plural → use They're. Also, add 's after a name: Ken's keys.

Question 6 / 10

What does Whose ask about?

Correct. Whose asks about ownership — who something belongs to. "Who" asks about identity.

Whose always asks about ownership: "Whose bag is this?" = who does this bag belong to?

Question 7 / 10

A: is this? B: It's my umbrella.

Correct. The answer says "It's" (singular) → question uses Whose umbrella is this?

The answer "It's my umbrella" is singular, so the question is Whose umbrella is this? (singular, not umbrellas).

Question 8 / 10

Whose lunch bag is this? It's .

Correct. Add 's after a name to show ownership: Emma's lunch bag.

To show a name owns something, add 's: Emma → Emma's. The apostrophe is required.

Question 9 / 10

Which question matches the answer "They're my shoes"? 哪個問句對應這個答句？

Correct. "They're my shoes" is plural → question must be Whose shoes are these?

"They're" signals plural. The correct question is Whose shoes are these? — plural noun + "are these".

Question 10 / 10

Which sentence has an error? 哪個句子有錯誤？

Correct. (D) has an error: "shoes" is plural → should be Whose shoes are these? not "is this".

The error is in (D). "Shoes" is plural, so use "are these" not "is this": Whose shoes are these?
