三、阅读还原。
Table manners are an important part of traditional Chinese culture. They show our respect for hosts, elders and other guests. Learning basic rules helps us behave well at the dinner table.
In China, people usually wait for the elders to start eating first. We should use chopsticks properly. Do not play with chopsticks, point at others, or knock on bowls. 1
Chinese people often share dishes together. It is polite to take proper food each time and not to be greedy. 2 Making loud noises while eating is considered rude.
When having meals, we should pay attention to our behaviours(行为). 3 It is also impolite to talk with food in your mouth. Besides, we should thank others when they serve us food.
4 We should value food and never waste it. 5 Different cultures have different customs, but respect is always the key.
Good table manners not only make meals more pleasant but also help us pass on our traditional culture.

1. 2. 3. 4. 5.

1. C 2. A 3. D 4. F 5. B

我们根据上下文逻辑逐一分析：
1. 空1前文介绍了中国餐桌礼仪里等长辈先动筷、正确使用筷子的基础规则，C选项“学习并遵守这些基本礼仪是很有必要的”承接上文内容，符合语境。
2. 空2后文提到吃饭发出大的声响被认为是粗鲁的，A选项“我们应该安静用餐，闭着嘴咀嚼”和后文内容呼应，衔接自然。
3. 空3后文出现"It is also impolite（这也是不礼貌的）"，说明前文提到了一种不礼貌的行为，D选项“在餐桌上玩手机是不礼貌的”符合此处逻辑，和后文的also对应。
4. 空4前文已经介绍了多条餐桌礼仪，后文引出要珍惜食物不浪费的新规则，F选项“我们还要记住很多其他重要的规则”起到过渡作用，符合语境。
5. 空5前文列举了多条餐桌礼仪要求，B选项“如果我们遵守这些规则，就可以礼貌地享用用餐”对前文的规则进行总结，引出后文不同文化都以尊重为核心的内容，逻辑通顺。
剩余E选项不符合文中各处语境，为干扰项。
