I together with/as well as/along with my grandparents has been collected to help those have been collected to help those 二、动名词作主语 1．直接位于句首作主语 In my opinion，cloning should be dealt with carefully. 我认为应该慎重对待克隆。 句式升级：动名词作主语可以使句子更加简练、高级。 Our school forbids us students to go out of the campus and we are strongly against it. →Forbidding us students to go out of the campus has raised a storm of objections. [练一练] We know of different cultures by learning English. →________________ gives us an access to an exploration of a variety of cultures. 2.用it作形式主语 为了避免句子“头重脚轻”，较复杂的动名词短语作主语时,可用it作形式主语，把动名词短语置于句末。 It is no good learning without practice. 学而不用无益。 常用句型：It＋be＋名词或形容词(no good，no use，useless)＋动名词 Learning English [练一练] 问我没有用，我也不知道。 ______________________ asking me，I don’t know either. 3．动名词的复合结构作主语 动名词有时可以在前面加上一个名词或代词的所有格，构成动名词的复合结构，在句中作主语。 Their coming to help was a great encouragement to us. 他们来帮忙对我们是一个很大的鼓舞。 It is no use 三、动词不定式作主语 1．直接位于句首作主语 To have a positive attitude is wise when we are let down. 当遭遇挫折时，怀有积极的态度是很明智的。 2．用it作形式主语 有时为了避免头重脚轻，常用it作形式主语，放在句首，将作主语的不定式放在句末。 常用句型一：It＋
