动名词和现在进行时的区别

Question

怎么区别动名词和现在进行时？
如(it is swimming)他又没有表示时间的词如now，怎么判断啊？
你怎么知道他说的是：它是游永，还是它正在游泳？
各位大侠介绍一下自己的判断方法！

Answer 1

现在分词呢，是由动词末尾加 -ing 形式构成，因此又叫动词的 -ing 形式。V+-ing
千万要注意V-ing形式的规则哟！
不能单独作谓语，没有人称和数的变化，可以有自己的宾语和状语。还有时态和语态的变化。见图
作主语：动名词
1Teaching is my full-time job.
2Writing an English composition is not easy.
3It’s useless taking this kind of medicine.
作表语
（1）动名词
My job is teaching.
= Teaching is my job.
Her full-time job is laying eggs.
=Laying eggs is her full-time job.
（2）现在分词
The play is exciting.
≠ Exciting is the play.
The story he told us was very interesting.
≠Interesting was the story he told us.
作表语
（1）动名词
My job is teaching.
= Teaching is my job.
Her full-time job is laying eggs.
=Laying eggs is her full-time job.
（2）现在分词
The play is exciting.
≠ Exciting is the play.
The story he told us was very interesting.
≠Interesting was the story he told us.
作宾语：动名词
I have just finished doing my home work.
I suggested asking his brother for some money.
He keeps buying expensive maps. He must have more than 200 by now.
只接动名词作宾语的常见动词有十六个：resist、mind、suggest、delay、keep on、look forward to、enjoy、include、appreciate、imagine、practise、finish、succeed in、consider、can’t help、miss。
作宾语补足语：现在分词
I heard the girl singing in the classroom.
I noticed a long queue outside the bank waiting for it to open.
The baby watched his dad shaving his face with great interest.
能跟现在分词作宾语补足语的常见动词有这些，看看有什么好方法可以将它们记住：
make、let、have、look at、see、watch、hear、listen to、notice、feel。
对了，用“三让、三看、两听、注意感觉”。多简单！
作定语
⑴动名词作定语表示性质或用途。
a washing machine
＝ a machine for washing
a swimming pool
＝ a pool for swimming
例：This is a new washing machine.
⑵现在分词作定语表示动作。如果是单词，放在被修饰的名词前；如果是短语，放就放在被修饰的名词之后。
a developing country ＝ a country which is developing
a sleeping boy＝ a boy who is sleeping
The man talking with my father is Mr. Wang.
China is a developing country.
作 状 语
现在分词作状语。表时间、原因、条件、结果、伴随（方式）等。
Hearing the cry for help, he rushed out.（时间）
Being ill, he went home. （原因）
Seeing from the hill, you can get the whole town.(条件）
European football is played in 80 countries, making it the most popular sport in the world. （结果）
He read a magazine waiting for the bus.（伴随）
V + -ing 形式用法归纳

Answer 2

动名词 的用法与名词相同，如可作主语、宾语等
现在进行时是作谓语的
it is swimming.谓语结构是be+动词ing，说明说话顺进正在发生，是现在进行时。翻译为“他是游泳”意思不明。
现在进行时不见得都要有now,主要还是看意思表达的是什么。
如：Swimming is my favorite sport.中的swimming表示一项运动，是动名词。

Answer 3

it is swimming中已经有it
it是主语 是主系表结构 is是系词
如果说Swimming is my favortie sport
Swimming 是动名词
是主系表结构

Answer 4

动名词是 v+ing 现在进行时是be+ving
