8、强调句型 教材例句 It was my sister who first had the idea to cycle along the Mekong River from where it begins to where it ends. 句型解读 强调句型It is/was…that/who 的用法归纳如下： 强调句型可以强调除谓语动词以外的任何句子成份。一般来说，如果被强调部分是人时，用连词that或who；如果被强调部分是物，只能用连词that。 强调句型应避免使用when, where, which 等连词。 含一般疑问句和特殊疑问句的强调句句型: ① 含一般疑问句的强调句型，其结构为：Is it+被强调部分+that/who+句子的其余部分？ ② 特殊疑问句的强调句型结构形式为：特殊疑问词+is/was it that/who+句子的其余部分？ 9、although/though引导让步状语从句 教材例句 Although she didn’t know the best way of getting to places,… 句型解读 Although conj. “尽管，虽然”，引导让步状语从句。拓展： ① although 从句多在句首， though 从句可在主句前、中、后任何位置，而且though 可以作副词用于句末，作“但是，不过”讲，而although 无此用法。 ② although 用来陈述事实而不用于假设，所以as though(仿佛，好像)，even though(即使，尽管)中不能用although。 ③ though 引导的让步状语从句可以倒装(将表语、状语、情态动词后的动词原形前置到句首，此用法同as),而 although 不可以。 10、once 引导时间状语从句 教材例句 Once she has made up her mind, nothing can change it. 句型解读 Once 可作为从属连词，作“一(旦)……就……”解，连接一个表示时间的状语从句。从句中常用一般现在时，现在完成时表将来。 如：Once you have begin you must continue. Once printed，the book will be very popular。 11.there be 句型 教材例句 Now, imagine there has been a big earthquake. 句型解读 “There +be +主语+其它成分”结构中there为引导词，本身无意义，谓语动词按照就近一致原则。其它相似句型还有： There happen to be 碰巧有 There seems/appears to be 好像有 There is likely to be 可能有 There may/might be 也许有 There must be 一定有 There can’t be 不可能有 There is said/reported to be 据说/据报道有 There used to be 曾经有 There is sure/certain to be 一定有 12.It seems/seemed that…从句 教材例句 It seemed that the world was at an end。 句型解读 从句表示“(在某人)看来好像；似乎” ① It seems/looks/appears as if/though…看起来好像… ② Sb./Sth. looks as if/though…(不用seem/appear) ③ There seems/appears(to be)…(不用 look) There appears to have been a mistake. =It appears that there has been a mistake. ④ It seems so. =So it seems.看来似乎是这样。 13、leave+宾语+宾补 教材例句 句型解读 “leave+宾语+宾补”结构中leave 作为及物动词，可以表示“使保留，让…处于(某种状态、某地等)”。其后接形容词、分词、不定式、介词短语、名词或句子等补足语。 如：① I’m sorry I’ve left some questions unanswered. ② He left the windows open. ③ Don’t leave her to cook for 20 minutes. 14、部分否定 教材例句 All hope was lost. 句型解读 该句为部分否定。All, both, everyone, everybody, everything 以及every+名词都表示全部肯定；但当not 在它们之前或之后都表示部分否定。no one, none nobody, nothing, not…any, 以及 no+名词都表示全部否定。如： ① Both of them haven’t read this story. 并非他们二人都看过这个故事。 ② All of the boys are clever, but none of them can work out this problem. 这些男孩都很聪明，但没有一个人能解出这道题。 ③ All bamboo doesn’t grow tall.=Not all bamboo grows tall. 并非所有的竹子都长的高。 (责任编辑：admin) |
