现在分词就是动词的-ing形式.do的现在分词就是doing
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.）
