hang
hang out 抓紧；别挂电话
hang up 挂断电话
hang back 犹豫；留下，吞吞吐吐
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 v. 给；递；走过；通过
Point
Language points

3. ①Could I borrow that book (教材P20 4a)
②Could you lend me some money (教材P20 4a)

Point
Language points
【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“借来”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
【拓展延伸】keep也可表示“借”，是延续性动词，常与表示一段时间的状语连用。keep sth. for some time表示“借用某物一段时间”。而lend与borrow是短暂性动词，不能与表示一段时间的状语连用。
【巧学妙记】主语借出用lend，主语借入用borrow，想要保存用keep。
Nick borrowed a book from the library and he lent it to me. He told me that I could keep it for a week.
