1. 句中时间状语为yesterday，应用pay的过去式paid。2. “支付”对应动词pay，此处为不定式结构，用原形pay。

探究点2 attention的用法
attention名词,意为“注意；专心；关注”。pay attention (to...)表示“注意；关注”,to为介词,后接名词、代词、动词 - ing形式、短语或者名词性从句。
The TV was on, but Mary wasn't paying attention to it. 电视开着,但是玛丽没注意看。
As Chinese, we should pay more attention to traditional culture.
作为中国人,我们应该更多地关注传统文化。
情境应用
1. Please pay attention to care of your baby. (take)
2. We should our spoken English. (关注)

1. taking
2. pay attention to

1. pay attention to中的to为介词，后接动词时要用动词-ing形式，所以此处应填taking。
2. “关注”对应的英文表达是pay attention to，should是情态动词，后接动词原形，所以此处填pay attention to。

探究点3 offer的用法
offer作动词,意为“提供；主动提出”。
|用法|例句|
|offer to do sth 主动提出做某事|She offered to lend me her bike. 她主动提出将自行车借给我。|
|offer sb sth / offer sth to sb 主动给某人提供某物|The young man offered the old man his own seat on the bus. = The young man offered his own seat to the old man on the bus. 那个年轻人在公共汽车上将自己的座位让给了那个老人。|

offer作名词,意为“主动提议；出价”。

他对这所房子出价很高。
情境应用
1. I think you might at least offer the old man! (help)
2. They offered me the book for 30 yuan. (改为同义句)
They the book me for 30 yuan.

1. to help
2. offered; to

1. 根据题意，需要填写动词help的适当形式。“offer to do sth”是固定搭配，表示“主动提出做某事”，所以这里应该用“to help”。
2. “offer sb sth”的同义结构是“offer sth to sb”，原句“They offered me the book for 30 yuan.”中“offered me the book”，可以转换为“offered the book to me”。
