42.be made考査固定词组。 sth be made of 精美的筷子可能非由金或银制成的筷子莫属。...某物由......制成，情态动词后跟动词原形，故填be made。
43.to create考査不定式作目的状语。技术娴熟的工人会把各种各样的硬质木材和金属结合起来，以创造出特殊风格的筷子。这里用不定式表目的，故填to create。
44.using考査现在分词作伴随状语。人们可能使用大锅煮食物，用树枝把锅移开，use的遗辑主语是people, 两者是主动关系，用现在分词表示伴随状况，故填using。
45.as/when考査时间状语从句。句意：随看人口的增长，人们开始把食物切成小块，这样可以煮得快一点， 这里是时间状语从句，when意为‘当......时候' 后跟长动作或短动作，故填as/when。

47.who考查非限制性定语从句 。剧中有逗号，说明是非限制性定语从句，先行词是Confucius孔子，定语从句缺少主语，且指人，故填who。48.development考查词性转换。the+名词+of，意为“……的……”，这里指“筷子的发展”，故填development。
49.were考查时态。根据句意可知，这里指的是刀子因太暴力而不适合在餐桌上使用，believed后跟一个宾语从句，and连接了两个并列的谓语，主语knives是复数，根据时态一致的原则，这里用一般过去时，故填were。
50.with考查介词。句意：在印度，大部分人还是用传统的吃饭方法——用手拿，with+表示具体工具的名词，故填with。
