Can yu find the cmmn features f these sentences?
情态动词culd可用于有礼貌地向对方提出要求或请求，也可用于提出建议。它本身不能作谓语，必须和不带t的动词原形一起构成谓语。
情态动词culd的用法
“Culd yu ” 意为 “能请你……吗？”，用于提出要求或请求。
Yes, sure/Of cusre. 是的，当然可以。
N prblem. 没问题。
With pleasure. 乐意帮忙。
Sure/Of curse/Certainly, I can. 当然可以。
—Culd yu please lend me yur bike? —Sure/Of curse/Certainly, I can.
否定形式为Culd yu please
Srry, I can't. I have t... 对不起，我不能，我得……
Srry, I'm ging t ... 对不起，我将……
I‘m afraid I can’t. I have t... 我恐怕不能。我得……
I'm afraid nt. 恐怕不行。
—Culd yu please g hiking with me tmrrw? —Srry, I can't. I have t prepare fr a cmpetitin.
“Culd ”意为“我能……吗？”，用于请求对方允许自己做某事。
—Culd I have a lk at yur new watch? —Of curse yu can. Here yu are.—Mum, culd I g ut fr a while? —I'm afraid yu can't. Yu have t wash yur clthes first.
Yes, yu can. / Of curse yu can. /Yes, please.
Srry, yu can't. /I'm afraid yu can't. /N, yu mustn’t.
Culd/Can I cme in?
表示请求允许（即请求别人允许自己做某事），culd和can都可以用，但culd语气更委婉。
—Culd I use yur pen? —Of curse yu can.
对别人的请求许可的回答，一般只用can，而不用culd.
culd 表示过去的能力，表示现在的能力用can。此时culd是can的过去式。
Culd yu speak English then?Lking dwn frm the plane, we culd see the light n the runway.
Yu culd be right, but I dn’t think yu are. (对现在的推测)We culd g there this summer. (对将来的推测)
① 后接动词原形，表示对现在或将来的推测。
Where culd he have gne?She culdn't have left s sn.
② 后接动词的完成式，表示对过去的推测。

“Yu culd...” 表示提建议，意为“你可以……” 。

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.

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。
