Passage Two
[29]When my husband was promoted, we put our house up for sale. Three weeks later, it was still on the market. I became a busy housekeeper. Every room had to be kept tidy, and dishes had to be washed and put away when used. Then one day the doorbell rang unexpectedly at 8 a.m. Sleepily, I opened the door and saw our agent standing there with a couple from New York. "There had been no time to call," he explained, "[30]because the couple had to catch a plane home."
The three people made their way past the dirty breakfast dishes on the kitchen table and into a bedroom with unmade beds. As I retreated into a bathroom to comb my hair, I heard the man say something to his wife. Then they both laughed.
Two days later, the agent phoned to tell me that the couple had bought the house. He repeated what the buyer had said when he handed over the check the following day: "[31]That house has a warm, lived-in feeling, just like ours."

Questions 29 to 31 are based on the passage you have just heard.
29. Why did the speaker sell her house?
正確答案：A
解析：短文開篇就說“丈夫升職后我們打算把房子賣了”，所以A正確。
30. Why did the agent call on the speaker so early in the morning?
正確答案：B
解析：短文中售房中介解釋了原因：來不及給你打電話了，因為他們得趕飛機回家。故B正確。
31. Why did the couple laugh in the speaker's house?
正確答案：D
解析：買房的夫妻倆發笑的原因就在售房中介轉述二人的話中，他們說“這所房子給人一種溫馨的家的感覺，就像我們的一樣。”由此可知選項D（他們看見了熟識的東西）為正確答案。
