动词­ing形式作表语可分为两种情况：现在分词和动名词。现在分词作表语主要表示主语的性质、特征和状态，而动名词作表语则主要是对主语内容的进一步说明，即主语等同于表语，两者可互换。 The situation both at home and abroad is very inspiring. 国内外的形势都很鼓舞人心。 Her job is washing, cleaning and taking care of the children. 她的工作是洗刷、打扫和照顾孩子。 练练悟悟 小测固新知 (1)表语一般用在系动词后面，系动词除be动词外还有appear，sound，look，become，come，get，go，grow，keep，remain，seem等。 (2)动词­ing形式用作表语时，相当于形容词，表示性质或状态；而进行时态中的动词­ing形式是谓语动词的组成部分，表示具体的动作，两者不可混淆。 The present situation is encouraging.(动词­ing形式作表语) 练练悟悟 小测固新知 目前的形势是令人鼓舞的。 The present situation is encouraging us to stride forward in production. 目前的形势正在鼓舞我们在生产上迈步前进。(现在进行时) (3)动名词(短语)作表语，表示抽象的一般性的行为，用来说明主语的内容，与主语通常是同一概念，表语和主语常可互换位置。 The police's job is keeping public order. → Keeping public order is the police's job. 练练悟悟 小测固新知 警察的工作就是维护公共秩序。 (4)动词­ing形式表示主语的某种性质和特征时，常用作表语，通常可以看作形容词。 The news that women astronauts will be sent into space is encouraging. 女宇航员将被送入太空的消息令人鼓舞。 The problem which he met in the new school is quite puzzling. 他在新学校遇到的问题很令人费解。 练练悟悟 小测固新知 【注意】表示“情感、情绪”类的动词，其­ing形式作表语表示主语所具有的特征，意为“(事物) 令人……的”；其­ed形式作表语则表示主语所处的状态，意为“感到……的”。这类词有：   现在分词形容词  过去分词形容词 现在分词 汉语意思 过去分词 汉语意思 amazing 令人惊奇的 amazed
