动名词（v- ing）的用法
语法定义
动名词是由“动词原形+-ing”构成的，但是它不是表示正在做，而只是表示“做……”这件事！“动词原形+-ing”有两种叫法，如果呈现的是名词词性就叫__________，呈现的形容词、副词词性时就叫 _______。动名词的构成和现在分词一样，但功能完全不同，动名词具有名词的功能，又保留了动词的性质。分词具有形容词、副词的功能且保留了动词的性质。因此动名词在句中作_______________________等。
“动名词”
“分词”
主语、宾语、表语、定语
Nothing great was ever achieved without enthusiasm
by是介词, 后接名词、代词或动名词作宾语, 意义较多, 归纳如下:
1. by表示方式、方法、手段等, 意为“通过/用/靠……(而达到某种预期的目的)”, by +doing sth. 意为“通过做某事”在句中作方式状语
—How can I turn on the computer
——我怎样能打开电脑
—By pressing this button.
——按这个按钮。
