补用不定式与现在分词时,含义不同,需特别注意,(参见现在分词部分)。试比较:

情况)

个过程)

(3)动名词
① 动名词由动词原形加词尾“ing”构成。动名词有动词的特征,可以跟宾语,可以被
状语修饰;它也有名词的特征,在句子中可以作主语、宾语(包括介词宾语)等。动名词加相关词语(宾语或状语等)构成动名词短语。
② 动名词可以作主语。一般可用it作形式主语而将动名词短语后移。如:Learning
English all by yourself is not so easy.(自学好英语不那么容易)(=It is not so easy learning English all by yourself.) ③ 动名词可以作宾语。
[A] want / need之后用动名词时,含有被动意思。如:Your car needs reparing badly.(你
的车急需修理。)(被修)My hair needs cutting.(我要理发。)(头发被理)
[B] remember / forge / stop / finish之后用动名词时,与用不定式含义不同。如:I
forgot to write a letter to him.(我忘了给他写封信)(根本没写) / I forgot writing a letter to him.(我忘了给他写过信)(写了却忘了) / They stopped to look back.(他们停下来向后看)(停下的目的是向后看) / They stopped looking back.(他们停止向后看)(不向后看了)
[C] enjoy / mind / keep / hate/ go等词一般用动名词作宾语。如:Do you mind my
closing the door?(把门关上你介意吗?)/ She hates travelling by air.(她讨厌坐飞机旅行)/ They went swimming every afternoon.(他们每天下午去游泳)/ I enjoy walking around the town.(我喜欢在镇上转悠)
[D] like / love / start / begin / learn后面用动名词时,与用不定式意思相近或相同。如:
We began to study English when we were at primary school.(我们在小学时就开始学英语了) / We began studying English when we were at primary school. (我们在小学时就开始学英语了)
④ 动名词可以作表语,此时特别注意不要与现在进行时混淆。如:My job is putting
these parts together.(我的事情是把这些部件拼起来) / I am putting these parts together.(我正在把这些部件拼起来) ..⑤ 动名词与现在分词构成相同,但是含义不同,动名词主要表示事情,而现在分词则主
要表示进行着的动作。如:Eating too much is not good for your health. (动名词短语,作主语) / Seeing is believing.(动名词短语,分别作主语和表语) / He ran after a moving bus and got onto it.(现在分词,作定语) / His father saw him sitting on some eggs.(现在分词,作宾补)
(4)分词: 包含现在分词和过去分词。(高中学习重点)
① 主要区别:现在分词一般有主动的意思或表示动作正在进行的意思;过去分词有
被动或动 作已经完成的意思。分词可以有自己的宾语或状语。 ② 分词或分词短语在句子中作定语、状语和复合宾语等。
