三个常被误用作连词的介词短语

摘要

请指出下列三句错在哪里:1.She failed in the exam because of she was careless.2.She is very good at physics in spite of she finds it boring.3.For the first time I saw him,I knew he was ambitious.介词之后常常接名词、代词、动名词、what引导的名词性从句来充当宾语;而连词后面要跟句子并跟该句子一起构成状语从句。句1中because of后面接了she was careless,这是一个由“主语+系动词+表语”构成的句子,而这类句子是不能作介词的宾语的,我们可以这样修改:She failed in the exam because she was careless.She failed in the exam because of her carelessness.
