2015届高三英语一轮写作技能培优：第一阶段第三讲第一课时如何写好主语.pptVIP

第三部分 写作技能培优;主语是一个句子中最重要、最核心的两个部分之一。 一、单词作主语 1．主语通常由名词、代词、数词或名词化的形容词充当 All efforts will be in vain if we can’t learn English by practicing repeatedly.(名词作主语) 如果我们不通过反复练习来学习英语，所有的努力将付之东流。;2.单词作主语时要注意谓语动词的单复数 (1)使用高级词汇(except，besides，with，as well as，together with，along with等)连接主语。(注意谓语动词一般与前面主语一致) The teacher with his students is going to visit the museum. 老师和他的学生们要去参观博物馆。 (2)使用高级量词(quantity，amount等)修饰主语。(注意谓语动词的单复数形式);[练一练] ①周六早晨，我和祖父母一起在网上查找列车时刻、北戴河的天气以及旅馆信息。 On Saturday morning，_______________________________ ______________________，searched the Internet for the train schedule，the weather in Beidaihe，and some hotel information. ②募集了大量的善款来帮助那些遭受水灾的人们。 →A large quantity of money __________________________ suffering from the floods. →Large quantities of money __________________________ suffering from the floods.;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。;[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??;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。;If they adjust their mind a little，it is not hard for them to find that life is just as promising as before. 如果他们对于思路稍加调整，就不难发现生活和以前一样充满阳光。;It’s rude of him not to invite you. 没有邀请你，他很失礼。 It is our responsibility to learn advanced science and technology to build socialism. 学习先进的科学技术来建设社会主义是我
