动词怎么转换成名词？名词怎么转换成动词？

你是问的哪国的语言嘛？！
如果是汉语就不用转，本身有两种用法就可以，没得的话就通俗称之为语法错误。
如果是英语就可以转为动名词
动名词可分为两大类：

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。

好，今天就谈到这里，更多关于动名词的事下回再谈。如果诸位不怕头晕的，请再来试
试，嘿嘿！

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):

1.1 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)

1.2 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)

1.3 主语置于句尾

1.3.1 用 It + be + ... +v-ing 句型

1. It is fun speaking English.
2. It is of great importance fighting against pollution(污染).

1.3.2 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.

1.3.3 用 It is 后接 useless, nice, good, interesting, worthwhile 等的句型

1. It is worthwhile taking this into consideration.

1.3.4 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)

动词基本上加ing就是名词了
