动名词的用法

动名词的用法及练习 你听过英文语法有动词(verb)、名词(noun);但你听过有动名词(gerund)吗 1. The girl is singing a song. 2. The girl singing now is my sister. 3. Singing is one of her hobbies(爱好). 一、名词性的动名词(Nominal Gerund) Nominal Gerund 可以加上定冠词(Definite article,如the)或不定冠词(Indefinite article,如a, an),其他可加在动名词前的还有如:my, this, some, any, all, no 等等。举例如下: 1. The mellow(愉快地) singing of the birds announces the coming of spring. (singing前加定冠词the及形容词mellow;coming 前加the) 2. We knew the robber was near when we heard a faint rustling(沙沙声) in the bushes. (rustling 前加不定冠词a及形容词faint) 从上面的例子可看出如何将一个动词转成名词;但它和真正的名词还是有区别的,那就是没有单数或复数之分。不过,有一些动名词是可以变成真正名词的喔,如:saying, writing, opening, painting, cutting, heading, feeling, being,saving, surrounding, crossing, misunderstanding 等等。它们都可以有复数的喔,方法就是在它们的后面加个s,如:paintings。 二、动词性的动名词(Verbal Gerund) 看看下面的句子: Carelessly writing essays annoys the teacher. 上面的句子里的writing是动名词,但前面有副词carelessly(粗心地),后面又有受词(Object) essays。因此writing就有动词的特征。 注意:Verbal Gerund 这类动名词的前面可不能加上任何冠词(the, a, an ...)喔。 动名词的功能与用法 一、在句子中用作主语(Subject)或主语的补语(Subject Complement): 作主语 1. Listening to music gives me pleasure. (主语Listening ) 2. Running is good exercise. (主语running) 3. Walking to school is a good idea. (主语walking) 作主语的补语 1. My cat's favorite activity is sleeping. (补语sleeping) 2. Seeing is believing. (主语seeing, 补语believing) 主语置于句尾用It + be + ... +v-ing 句型 1. It is fun speaking English. 2. It is of great importance fighting against pollution(污染). 用It is 后接no use. no good, fun 等的句型 1. It is no use learning theory without practice. 2. It is no fun being lost in rain. 用It is 后接useless, nice, good, interesting, worthwhile 等的句型 1. It is worthwhile taking this into consideration. 用There + be + no + v-ing 的句型 1. There is no joking about such matters. 2. There is no getting along with him. (简直无法与他相处) 二、动名词也可以作宾语(Object) 作动词/动词短语的宾语(置于动词或动词短语的后面) 1. I cannot help laughing. (我禁不住笑了起来)(宾语laughing) 2. You should avoid quarrelling with your sister. (宾语quarrelling) 3. You should practice speaking English more. (宾语speaking) 注意:上面三个句子中的动词:help, avoid, practice 只能用动名词作宾语。这类动词还有:dislike 厌恶admit 接受repent 后悔acknowledge 承认

keep 的用法

Keep的用法: keep vt., vi. kept, keeping 保留;保守 I keep old letters.我保存旧信。 I'll keep the original copy of your report on file. 我会把你报告的原件归档的。 It's an interesting suggestion and we'll keep it on ice." 这是一项有趣的建议,我们将留待以后考虑采用。" 保持;继续 We will keep on trying and, if we get anything done, will notify you. 我们将继续努力,有结果将通知你。 Leaders shouldn't keep themselves aloof from the masses. 领导人决不应该脱离群众。 Keep calm!安静!

SINCE的用法结构及修饰对象

说到since,我们最熟悉的用法或许就是“since前面要用现在完成时态”,其实,since还有其他不同的用法,这些用法容易被大家忽略。本期笔者就来系统梳理since的用法,定会让大家开阔眼界。 since用法的思路体系 下面笔者从两个角度来考察since的用法:一是since后面的结构特点;二是since前面的修饰对象特点(这是本期内容的重点)。笔者先给结论,然后再举例论述。请看下列表格。 从以上表格我们看到,一方面,从since后面所跟的结构特点来看,可以分为三种情况。 a. since后面接一个从句,此时since是连词(conjunction)。 b. since后面接一个名词短语,此时since是介词(preposition)。 c. since后面不接任何东西,而是单独使用,此时since是副词(adverb)。 另一方面,从since前面的修饰对象来看,也可以分为三种情况。 1. 修饰谓语动词:此时作时间状语(本文不讨论since作原因状语的情况),谓语动词的时态多用现在完成时态(have done),但根据语境和时间关系,谓语动词也可能用过去完成时态(had done)。 3. 修饰普通名词:此时作后置定语,普通名词是相对于“最高级名词”而言的。 现在,我们可以把上面两方面因素各三个变量进行排列组合,得出since各种用法的句子。下面一一举例来说明。 since修饰谓语动词 我们首先来看一个例句。 他有生以来遭遇过多次困境。 b. he has faced many difficult situations since last year. 自去年以来,他一直屡遭困境。 c. he began to get into trouble last year and has faced many difficult situations (ever) since. 他去年开始陷入困境,此后一直屡遭窘境。 解析:我们看到,b句中since后面接了名词短语last year,而c句中since后面没有接任何成分,此时也可以说ever since。 另外,值得注意的是,在特定的上下文语境中,since前面可以使用过去完成(进行)时态。请看下面一组例句。 2. a. mr. bin laden has been hiding since 2005. b. mr. bin laden had been hiding since 2005. 解析:a句用现在完成进行时态,这意味着本拉登到现在还没有死亡,仍在潜逃。而实际上,他已经于2011年被击毙,因此为了符合这一实际情形,b句用了过去完成时态来表达。 since修饰“最高级名词” 请比较下面例句。 他有生以来遭遇过多次困境。 他将会遇到有生以来最困难的境况。 他将会遇到从2000年以来最困难的境况。 另外,我们还可以采用“in +时间段”来替换“sin ce +时间点”,用于限定最高级的时间范围。比如,今年是2016年,于是例3的c句中的since 2000就相当于说in 16 years,我们可以把c句改成这样一句话。 他将会遇到16年以来最困难的境况。 英国正遭到60年以来的最严寒的冬天。 在正文中,作者继续详细讲述,又出现了两个“since+时间点”及“in +时间段”与最高级搭配的句子。
