例6 Neither her parents nor her teacher have persuaded her to change her mind. Y>*{(QD
(二)虚拟语气方面的错误 7Pu.<b}
做这类题考生首先要掌握虚拟语气的构成和主、从句的搭配,熟记常见的虚拟语气类型以及一些特殊用法,重点掌握下列常用的要引起虚拟语气的形容词和动词。 /*DC`,q

C D Tdvw7I-q
(三)非谓语动词的误用 YGb&mD
这一类的试题设计比较灵活,如果考生对各种非谓语动词(动词不定式、动名词、分词)的句法功能及用法没有透彻的了解,对它们与谓语动词、逻辑主词、逻辑宾词和其他词类之间的搭配关系掌握得不好,就很难解题。比如,下列动词或词组后面只能跟动词分词:enjoy, finish, appreciate, avoid, miss(错过), mind(介意), deny, admit, keep, prevent, consider, look forward to, can not help, object to, turn to (求助于), adapt to,等等。 )r_zM~jI
