上几期学习了英语语法: 短语bas it were, at one’s best的用法、短语be anxious to, be compelled to do sth的用法、短语be determined to, be forced to do sth的用法、短语be glad to, be happy to do sth的用法、短语be likely to, be obliged to的用法关注微博：@读外刊学英语
短语的用法13. be reluctant to do sth不情愿做某事
用法：be reluctant to后面跟动词原形，其同义短语有be unwilling to。
例句1：Big banks have been reluctant to switch to more secure technology because of the higher costs involved. (6月六级)
因为成本较高，大银行一直不情愿转向更安全的技术。
结构分析：Big banks是主语，have been reluctant是系表型谓语（系动词have been+表语reluctant）， to switchto more secure technology是不定式词组作宾语，because of the higher costs involved是because of引导的原因状语（involved是过去分词作后置定语）。
14. be unlikely to不太可能
用法：be unlikely to后面跟动词原形，其反义词组是be likely to。
例句1：They are unlikely to break their career trajectory to raise afamily. (6月四级)
她们不太可能为了照顾家庭打破自己的事业轨迹。
结构分析：They是主语，are unlikely系表型谓语（系动词are +表语unlikely），to break their career trajectory to raise a family是不定式词组作宾语（to raise a family是状语）。
