动名词与不定式作主语在结构上的差异

一、在含有no或less等否定词的句子里，一般不用不定式（短语）作主语，而用动名词（短语）作主语。但在用not否定谓语的句子里却可以用不定式。常见的结构是：Itisnouse（goodhelp）doing…；Itisuselessdoing…如：１．Itisnouselearningthetextbyheartwithoutunderstand鄄ingit．背书而不懂意思是没有用的。２．Itisuselessdiscussingthematter．讨论这事是没有用的。ItisnoteasytostudyEnglishwell．学好英语并不容易。二、动名词可以作therebe这种句型的主语，不定式则不能。例如押１．Thereisnodenyingthefact．事实不可否认。２．…

no one与none

no one和none的汉语意思相近,但用法却有区别。1.no one相当于nobody,二者可以通用,均用来指人,但no one只表示人,后面不能接of短语;none既可指人,又可指物,后面常接“of+the/m y/your/this/that+名词”构成的介词短语。例如:There is no one/nobody here.这里没有人。N o one/N one in this class is late for school.这个班没有一个学生上学迟到。N one ofthe film s are/is good.这些电影中没有一部是好的。2.no one为单数意义,在句中用作主语时,谓语动词应为单数形式;而none作主语指可数名词时,谓语动词用单复数形式均可;none指不可数…

英语名词作主语时和动词谓语的搭配

根据英语语法规则的要求,英语的主语要与其谓语动词在人称、数和格三方面保持一致。本文主要讨论的是名词作主语时和谓语动词的搭配问题,现特从以下几个方面讨论之。一、确定真正的主语下面例句中,就是由于动词的真正主语没有确定而发生的错误。例1:桌子上有一箱鸡蛋。误:A box of egg are on the table. 正:A box of egg is on the table。这句话的主语是单数“一箱”而不是复数“鸡蛋”。故要用“is而不是用“are”。

点拔it作形式主语

当动词不定式(短语)、动名词(短语)或者从句作句子的主语时,通常用it来作形式主语代替它们,而将真正的主语放在后面,以保持句子结构的平衡。例如:It is difficult to complete the mission on my own.独立完成这项使命是很难的。(真正的主语是to complete the mission on my ow

浅析英语独立主格结构

独立主格结构没有主语和谓语，所以在语法上不是句子。但它是一种具有逻辑主谓关系的独立结构，其逻辑主语多有名词或代词充当，逻辑谓语主要由分词、不定式、名词、形容词、副词或介词短语担任。独立主格结构常位于句首或句末，常用逗号与句子其它成份隔开，一般只用于书面用语。 一、独立主格结构的主要构成形式 １．名词（代词）＋分词 It being Sunday today, we have no classes. 今天是星期天，我们不上课。 ２．名词（代词）＋不定式 The mid-term examination is over,the terminal examina-tion to cme in two months. 期中考试…

主谓一致特例种种
