英语写作：如何写好主语.ppt

第一课时如何写好主语 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保持一致) 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) 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 has_been_collected_to_help_those_suffering_from_the_floods. →Large quantities of money have_been_collected_to_help_those_suffering_from_the_floods. 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。 常用句型：It＋be＋名词或形容词(good，no good，no use，fun，pleasure，better，wonderful，enjoyable，interesting，foolish，difficult，useless)＋动名词 。 It is no good learning without practice. 学而不用无益 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。 [练一练] 翻译句子 ①我们不可能按时把这项工作完成。 It_is_impossible_for_us_to_finish_the_work_on_time. ②你帮助我做这项工作，真是太好了。 It’s_very_kind_of_you_to_help_me_with_the_work. ③在这里发言我很荣幸。 It’s_an_honor_to_make_a_speech_here. ①Read as much as possible is necessary.(×) ②Reading as much as possible is necessary.(√) ③It is necessary to read as much as possible.(√) [练一练] 翻译句子 ①人们通常认为足够的新鲜空气有助于保持健康。 It_is_widely_believed_that_plenty_of_fresh_air_contributes_to_good_health. ②我突然想起做这项工作不是一个挑战而是一个机遇。 It_occurred_to_me_that_it_was_not_a_challenge_but_a_chance_to_do_such_a_job.
