1. knocking
2. show up
3. empty
4. situations

1. “without”是介词，后面接动词的 -ing 形式，“knock on the door”表示敲门，所以这里填“knocking”。
2. “didn't”后面接动词原形，“show up”表示出现，符合语境，即他直到聚会结束才出现。
3. “hands”是名词，前面用形容词修饰，“empty”表示空的，“with empty hands”表示空着手。
4. “different”后面接名词复数形式，“situation”表示情况，这里说在不同的情况下要了解基本的餐桌礼仪。

课文再现 第一次空手出现在别人家是不礼貌的。It's impolite to at someone's house for the first time with empty hands.
迁移运用 1. 我将带我的父母参观一下我们学校。I will my parents our school.
2. 请出示你的票! your ticket, please!
3. 我一等再等,但是他始终没有露面。I waited and waited but he never .

show up；show around；Show up；showed up

课文再现：“出现”对应短语“show up”，It's impolite to后接动词原形，故填show up。迁移运用1：“带某人参观”是“show sb. around”，will后接动词原形，填show around。2：“出示”用“Show up”，祈使句以动词原形开头，填Show up。3：“露面”是“show up”，根据waited可知用一般过去时，show的过去式是showed，填showed up。
