一、现在分词
现在分词由动词加ing构成。
非谓语动词中的现在分词主要起形容词和副词的作用，在句中作定语、表语、补语或状语。
一、现在分词的两个基本特点。
1. 在时间上表示动作正在进行。例如： a developing country. 一个发展中的国家， boiling water 沸水， rising sun 冉冉升起的太阳。（试比较： a developed country 一个发达国家， boiled water 白开水， risen sun 升起的太阳）
2. 在语态上表示主动。例如： the ruling class 统治阶级， the exploiting class 剥削阶级。（试比较： the ruled class 被统治阶级， the exploited class 被剥削阶级）
二、掌握现在分词的基本功能。
1. 现在分词作定语，表示正在进行的或主动的动作。也可以说明被修饰词的性质和特征，此时可换成相应的定语从句。例如：
① There was a terrible noise following the sudden burst of light.
② He saw a flying bird and raised his bow.
③ I was satisfied with the exciting speech.
2. 现在分词作状语时，可作时间、条件、结果、原因和伴随状语，表示正在进行的或主动的动作。此时分词的逻辑主语就是主句的主语，因此要注意人称、时态和语态的一致性。例如：
① The visiting minister expressed his satisfaction with the talks, adding that he had enjoyed his stay here.
② European football is played in more than 80 countries, making it the most popular sport in the world.
③Seeing from the top of the hill, we can find that the city looks more beautiful.
3. 现在分词作补足语，表示正在进行的或主动的动作。例如：
① Soon they could see the steam rising from the wet clothes.
② The missing boys were last seen playing near the river.
4. 现在分词的独立主格结构作状语。例如：
① With his lips still trembling, he couldn't say a word.
②“ Mama! ” he cried suddenly, tears rolling down his cheeks. “妈妈！”他突然哭着喊，泪水从他的脸上流下来。（这里需要用现在分词的独立主格结构 tears rolling down his cheeks 作状语。）
③ Weather permitting, we'll go to the Great wall. 如果天气允许的话，我们就去长城。（这里需要用现在分词的独立主格结构 Weather permitting 作状语。）本回答被提问者采纳
