問題探究
【知識點撥】
1.Could you please pass me the salt?你能遞給我鹽嗎?
pass 意為“傳遞”,可直接跟雙賓語,“把某物傳遞給某人”的結構為pass sb.sth.,或pass sth.to sb.。類似此用法的詞還有give,lend,bring。
例句:I pass my father a cup of water.=I pass a cup of water to my father.我遞給爸爸一杯水。
2.Could I borrow that book?我可以借那本書嗎?
(1)borrow 意為“借”,“向某人借某物”的結構為borrow sth.from sb.。
例句:I borrowed a bike from Tom.= I borrowed Tom a bike.昨天我向湯姆借了一輛自行車。
(2)borrow的反義詞是lend,意為“借給;借出”。“把某物借給某人”的結構為lend sb.sth.或lend sth.to sb.。
例句:Mary lent her new dictionary to me.=Mary lent me her new dictionary.瑪麗把她的新詞典借給了我。
