hang together (观点等)前后一致
2. Could you please pass me the salt (教材P20 4a)
pass在此处为及物动词，意为“给；递”。pass sb. sth. = pass sth. to sb.，意为“把某物递给某人”。如果sth. 为代词，只能用pass sth. to sb. 结构。
pass /pɑ s/ ,/p s/ v. 给；递；走过；通过

3. ①Could I borrow that book (教材P20 4a)
②Could you lend me some money (教材P20 4a)
borrow / b r / ,/ bɑ r / v.借；借用 lend /lend/ v. 借给；借出
【易混辨析】 borrow与lend
例词 含义 常用结构
borrow “借；借用”，指主语从别人处“借入”东西自己使用。 borrow sth. (from sb.)
（向某人）借某物
lend (lent, lent) “借给；借出”，指主语把自己的东西“借出”给别人使用。 lend sth. to sb.
=lend sb. sth.
把某物借给某人
【拓展】lend与borrow是短暂性动词，不能与表示一段时间的状语连用。表示 “借用某物一段时间”时，要用keep sth. for some time。
Nick borrowed a book from the library and he lent it to me. He told me that I could keep it for a week.
【巧学妙记】主语借出用lend，主语借入用borrow，
想要保存用keep。
