1. A . they have 为 difficulty 的定语从句。 developing.....为结果状语。2。 A 。 that引出定语从句修饰the day. that在从句中做宾语。3。 B. one uses ......为定语从句。 全句可译为：这就是今天人们用来生产塑料的那种材料吗？

1 A have difficulty doing sth 2 A 倒装句中用that3 b 定语从句省略了material后的that ,one做uses的主语,省略的that做use的宾语

第一题只能是a，如果有they had developing则更好，这考的是固定搭配have difficulty （in） doing sth的用法，定语从句（that）they have起干扰作用第二题是全倒装，但答案选择 和倒装无关，a和b都对，不填也对，缺的是关系代词，做宾语，可省略第三题b是对的，要用（that）one uses to make（定语从句） 或used to make（过去分词做后置定语），或that is used to make

我好就不用语法了,微薄意见,仅供参考.1.B,overcame是该句的谓语动词,我认为AC中的主语they重复了.2.B,在这句话中,应用连接词that3.A,不仅被动而且省略了连接词.
