9、sed by the Internet,Retell,1.I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage.【分析】该句是一个由and连接的并列复合句。and后的分句的结构是：it took.before.。before引导时间状语从句。,【翻译】我发展缓慢，差不多两百年之后，查尔斯巴比奇才把我制成了一台分析机。【仿写】过了两年我们才又见了一次面。_,It took two years before

10、 we saw each other again.,2.By the 1940s I had grown as large as a room,and I wondered if I would grow any larger.【分析】这是一个由and连接的并列复合句。and后的分句中，I wonder if.是一个常用句型，意为“我想知道是 否”，常用来委婉地提出疑问或 请求，也可用whether代替if。如：,As time went on,Mary began to wonder if/whether John had forgotten their date.,【翻译】到二十世纪四十年

13、y became too large for me to believe it.,e.g.He is so old that he cant carry the box.He is too old to carry the box.,此结构中的that从句表示结果。e.g.The stone is so heavy that no one can lift it.,so.that.结构的so+形容词/副词位于句首时,句子用倒装结构。e.g.So hard does he work that he seldom goes home.,so that既可以表结果,也可以表目的。,5.But I w

14、as always so lonely standing there by myself,until in the early 1960s they gave me a family connected by a network.【分析】本句是一个复合句。主句为I was always so lonely standing there by myself，其中standing there by myself是动词-ing形式短语作状语；,从句是由 _ 引导的时间状语从句，其中connected by a network是过去分词短语作后置定语，修饰 _。【翻译】但是我总是孤孤单单地站在那里，直
