Question 1 / 10

she a nurse? Yes, she is.

Correct. "She" is singular → use Is she a nurse?

"She" is singular → use Is. "Are" is for you/we/they; "Am" is only for I.

Question 2 / 10

A: Is he a farmer? B: No, he ___. He's a doctor.

Correct. "He" → negative is isn't (= is not). "Aren't" goes with you/we/they.

"He" uses isn't (= is not) for the negative. "Aren't" goes with you/we/they.

Question 3 / 10

A: Are you a student? B: ___

Correct. "Are you?" → answer with Yes, I am. (switch the pronoun to "I").

"Are you?" is directed at "you" — you answer as "I". So the correct answer is Yes, I am.

Question 4 / 10

"isn't" is the contraction of ___

Correct. isn't = is not. Compare: aren't = are not; don't = do not.

isn't = is not. "Aren't" = are not. "I am not" does not have a common contraction in standard English.

Question 5 / 10

A: Is she a cook? B: No, ___ isn't. She's a nurse.

Correct. The question asks about "she" → answer uses she isn't.

The question is about "she" → keep the same pronoun: No, she isn't.

Question 6 / 10

A farmer works on a ___

Correct. A farmer works on a farm. A doctor works in a hospital; a cook works in a kitchen.

A farmer works on a farm. Doctor → hospital; Cook → kitchen; Teacher → school.

Question 7 / 10

I a teacher? Yes, you are.

Correct. "I" uses Am in questions: Am I a teacher?

"I" pairs with Am. The question form is Am I a teacher? (not "Is I" or "Are I").

Question 8 / 10

A: Are you a doctor? B: No, I'm not. I'm a ___

Correct. After "No, I'm not," we name a different occupation. Nurse is a valid alternative job.

After "No, I'm not," we say what the person IS. (A) repeats the same job; (D) is not a proper job title. Nurse is correct.

Question 9 / 10

Which sentence is correct? 哪個句子正確？

Correct. "They" is plural → use Are they farmers?

"They" is plural → use Are. "Is" is for he/she/it (singular). So the correct sentence is "Are they farmers?"

Question 10 / 10

A: Is he a nurse? B: ___

Correct. (D) gives a proper negative answer and names a different job: No, he isn't. He's a farmer.

(A) is wrong — "aren't" goes with they/you. (B) says he isn't a nurse then calls him a nurse — contradiction. (C) uses wrong pronoun. (D) is correct.
