Correct Answer: A

Main idea: Y answers “No, thanks.” This response fits best when X is offering help/service.

A. Correct. “What can I do for you?” is a common service offer, and “No, thanks” is a natural refusal.

B. Incorrect. It is not a complete, well-formed question; the punctuation and structure are awkward.

C. Less appropriate. Grammatically possible, but it usually follows after someone has already asked for help; it sounds too specific without context.

D. Incorrect meaning. This asks Y to help X, but Y’s “No, thanks” suggests X is offering help to Y.

E. Incorrect meaning. This also requests help from Y, not an offer to Y.

Correct Answer: C

Main idea: The shopkeeper is offering assistance. The most natural offer in a store is “May I help you?”

A. Incorrect. This asks the customer to help the shopkeeper (“you help me”), not the other way around.

B. Incorrect meaning. It again asks the customer to help the shopkeeper.

C. Correct. “May I help you (to try the shoes on)?” matches the situation, and the refusal “No, thank you. I can do it myself.” fits perfectly.

D. Incorrect meaning. It asks the customer to help the shopkeeper, and the tone is odd in a service offer.

E. Incorrect meaning and too strong. “Do you object…” is confrontational and not used for polite service offers.

Correct Answer: C

Main idea: “Oh, poor Bob. I hope he'll be better soon.” shows concern and compassion for someone’s misfortune, which is sympathy.

A Incorrect. There is concern, but the main function is not expressing personal sorrow; it is expressing care for Bob.

B Incorrect. No happiness is shown.

C Correct. The speaker shows sympathy toward Bob’s condition.

D Less precise. “Hope” can involve expectation, but the social function here is sympathy.

E Incorrect. No satisfaction is shown.

Correct Answer: B

Main idea: “I am sorry to hear that” is a fixed expression used to show sympathy when hearing bad news. It is not an apology for something the speaker did.

A Less accurate. The speaker may feel disappointed, but the expression mainly functions as sympathy toward Jane.

B Correct. This is a standard sympathy response.

C Incorrect. Displeasure implies annoyance; the tone is caring.

D Incorrect. Apology is used when the speaker is at fault; here the speaker is reacting to someone else’s situation.

E Incorrect. No anger is shown.

Correct Answer: E

Grammar focus: “By then” (by next Monday) indicates an action that will be completed before a future time, so we use future perfect: “will have finished.”

A Incorrect. “Would” typically needs a past context or conditional structure.

B Incorrect. Present continuous does not match “next Monday” + “by then” completion idea.

C Incorrect. Present perfect does not fit a specific future deadline.

D Less accurate. “Will be finishing” suggests the action is in progress at that time, but the context implies she will be done and can lend it.

E Correct. “I will have finished reading it by then” means it will be completed before next Monday.

Correct Answer: B

Main idea: Reno responds “Of course,” which means he accepts an offer. Therefore, Koko must be offering help, not asking for help.

A Incorrect. This asks Reno what Koko can do for him, but the situation is about Reno’s unfinished report.

B Correct. “Would you like me to help you?” fits perfectly with “Of course. I'll be very happy then.”

C Incorrect. This asks Reno to help Koko, opposite of the context.

D Incorrect. This asks for a favor from Reno, opposite of offering help.

E Incorrect. This again asks Reno to do something for Koko, not an offer.
