【题目】第三节 单句改错 (共5小题；每小题1分，满分5分)

【2】The three Bronte sisters adopted this practice.，Mary Ann Evans did the same.

【3】We decided to fight against this unfair system which prohibits us blacks sitting where we like.

【4】Our friendship had developed quickly over the weeks that followed.

【5】Maybe if I studied science then, I would have been able to give more help.

Answer 1

【答案】

【1】Struggled改成Struggling

【2】adopted 改成adopting或在Mary前加and

【3】sitting前加from

【4】去掉had

【5】studied 前加had

【解析】

试题分析：

【1】Struggled改成Struggling Helen Keller和Struggle之间是主动关系，所以用现在分词做原因状语，故把Struggled改成Struggling。

【2】adopted 改成adopting或在Mary前加and 根据句意adopted的主语是The three Bronte sisters，主动关系；did的主语是Mary Ann Evans。所以把adopted 改成adopting就变成了现在分词短语做原因状语；

如果在Mary前加and则变成了一个并列句。故把adopted 改成adopting或在Mary前加and。

【3】sitting前加from 固定形式：prohibit sb. from doing 阻止某人做某事，故在sitting前加from。

【4】去掉had 句意：我们的友谊在接下来的好多周里发展得很快。这里只是在讲一件过去的事情，故去掉had 。

【5】studied 前加had 考查虚拟语气。句意：或许我那时学习科学，我见能给更多帮助。与过去的事实相反，故在studied 前加had。
