1. A . they have 為 difficulty 的定語(yǔ)從句。 developing.....為結(jié)果狀語(yǔ)。2。 A 。 that引出定語(yǔ)從句修飾the day. that在從句中做賓語(yǔ)。3。 B. one uses ......為定語(yǔ)從句。 全句可譯為：這就是今天人們用來(lái)生產(chǎn)塑料的那種材料嗎？

1 A have difficulty doing sth 2 A 倒裝句中用that3 b 定語(yǔ)從句省略了material后的that ,one做uses的主語(yǔ),省略的that做use的賓語(yǔ)

第一題只能是a，如果有they had developing則更好，這考的是固定搭配have difficulty （in） doing sth的用法，定語(yǔ)從句（that）they have起干擾作用第二題是全倒裝，但答案選擇 和倒裝無(wú)關(guān)，a和b都對(duì)，不填也對(duì)，缺的是關(guān)系代詞，做賓語(yǔ)，可省略第三題b是對(duì)的，要用（that）one uses to make（定語(yǔ)從句） 或used to make（過(guò)去分詞做后置定語(yǔ)），或that is used to make

我好就不用語(yǔ)法了,微薄意見,僅供參考.1.B,overcame是該句的謂語(yǔ)動(dòng)詞,我認(rèn)為AC中的主語(yǔ)they重復(fù)了.2.B,在這句話中,應(yīng)用連接詞that3.A,不僅被動(dòng)而且省略了連接詞.
