【易错点】
易错点 1：not only...but also...,both....and.....,either....or.....,neither.....nor....的区别
【典例】Not only the students but also the teacher was against the plan.
【精讲】① not only... but also...意为“不但……而且……”，连接并列成分，当连接两个并列主语时，谓语动
词遵循“就近原则”，即与 but also 后面的主语在人称和数上保持一致。
②both... and...意为“……和……(两者)都”，连接两个并列的句子成分，作主语时谓语动词用复数形式。
③neither... nor...意为“既不……也不……”，连接两个主语时，谓语动词遵循“就近原则”，即与 nor 后面的主
语在人称和数上保持一致。neither... nor...含有否定含义，所以谓语动词用肯定形式。
④either...or...意为“或者……或者……；不是……就是……”，连接两个主语时，谓语动词遵循“就近原则”，
即与 or 后面的主语在人称和数上保持一致。
易错点 2：take place 与happen 的区别
【典例】Great changes have taken_place in our hometown.
【精讲】take place 意为“发生”，常指事先安排或有准备的事情、活动发生。happen 意为“发生”，常指具体
事件的发生，特别是偶然的或未能预见的事；happen 还可表示“碰巧”，后常接动词不定式作宾语。
易错点 3：achieve 与come true 的区别
【典例】I believe I can achieve my dream.
2
【精讲】① achieve 为及物动词，意为“实现；完成”，主语通常是人，可用被动语态。
②come true 为不及物动词短语，意为“实现”，主语通常是梦想、理想、愿望等，无被动形式。
