　　①The girl is easy to get along with. 这个女孩很容易相处. ②The question is_difficult_to_answer. 这个问题很难回答. ③The house is comfortable_to_live_in. 这所房子住起来很舒服. 【重点提示】　我们可以看出这类形容词是用来描述主语的特征或性质的,此句型可以改写成to do sth.is/was＋adj..例：The girl is easy to get along with.→To get along with the girl is easy.另外,要注意当不定式后的动词为不及物动词时,要带上适当的介词. 3(教材P12)If_so,it is time for you to think again. 如果这样的话,你需要再考虑一下了.

　　【句法分析】If so是“If it is so”的省略形式,此省略原则为当从句中的主语是it或主、从句的主语一致,谓语动词又含动词be时,可把“it”或其他主语和动词be一起省略. ①He may not be at home then,if so,leave him a note. 他可能不在家,如果那样的话,给他留个条儿. ②He looked everywhere as_if(he_was)in_search_of something.他到处张望,好像在找什么东西.
