【知识点拨】
1．Could you please pass me the salt？你能递给我盐吗？
pass 意为“传递”，可直接跟双宾语，“把某物传递给某人”的结构为pass sb.sth.，或pass sth.to sb.。类似此用法的词还有give，lend，bring。
例句：I pass my father a cup of water.＝I pass a cup of water to my father.我递给爸爸一杯水。
2．Could I borrow that book？我可以借那本书吗？
(1)borrow 意为“借”，“向某人借某物”的结构为borrow sth.from sb.。
例句：I borrowed a bike from Tom.＝ I borrowed Tom a bike.昨天我向汤姆借了一辆自行车。
(2)borrow的反义词是lend，意为“借给；借出”。“把某物借给某人”的结构为lend sb.sth.或lend sth.to sb.。
例句：Mary lent her new dictionary to me.＝Mary lent me her new dictionary.玛丽把她的新词典借给了我。
