finish ding sth. 做完某事
1. Culd I hang ut with my friends after the mvie? (教材P20 4a)
hang ut为固定短语，此时hang的过去式和过去分词均为hung。
She is hanging ut with her friends in the shpping mall.
【拓展延伸】 含hang的其他常见短语：
hang ut 抓紧；别挂电话
hang up 挂断电话
hang back 犹豫；留下，吞吞吐吐
hang tgether (观点等)前后一致
2. Culd yu 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. t sb.，意为“把某物递给某人”。如果sth. 为代词，只能用pass sth. t sb. 结构
pass v. 给；递；走过；通过
He passed me the magazine. = He passed the magazine t me.This ball is Owen's. Please pass it t him.
【拓展延伸】 pass作动词的其他常见含义：

3. ①Culd I brrw that bk? (教材P20 4a) ②Culd yu lend me sme mney? (教材P20 4a)
brrw v.借；借用 lend v. 借给；借出
【易混辨析】 brrw与lend
【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. fr sme time表示“借用某物一段时间”。而lend与brrw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brrw，想要保存用keep。
Nick brrwed a bk frm the library and he lent it t me. He tld me that I culd keep it fr a week.
