人教必修二UNIT 3核心考点专讲专练【考点剖析】arise vi. (arose, arisen)出现;发生;起身;起床;上升[温馨提示]arise为不及物动词,没有被动语态。

arise 作“发生;出现〞讲时,主语多为抽象名词,如argument,problem,quarrel,question等。

【易混辨析】arise, arouse,rise与raise原形过去式过去分词现在分词含义arise (vi.) arose arisen arising在现代英语中主要用于借喻,指“出现;发生;产生〞。

arouse(vt.)aroused aroused arousing 指“唤醒;激起〞,后常跟抽象名词。

rise (vi.) rose risen rising使用范围较广,指“升起;上升;增长〞,也可指“起立;起床;地位升高〞等。

raise (vt.)raised raised raising用在句中,后面需跟宾语。

一般指“升起;举起;增加(程度、价格等);提高(音量);提出;种植(农作物);养育;抚育(子女)〞。

I developed very slowly and it took nearly two hundred years before I was builtas an analytical machine by Charles Babbage.我发育非常缓慢,差不多到了两百年之后,查尔斯·巴比奇才把我制成了一台分析机。

句型公式：It tak es some time before…过了一段时间之后才……【句式点拨】before 引导时间状语从句时,用以表示主句动作发生在从句动作之前,译法灵活。

(1)强调主句动作发生在从句之前,意为“不等……就……〞。

(2)在“It+be+时间段+before从句〞中,意为“……之后才……〞。

(3)在“It+be+否认形式+long+before从句〞中,意为“……不久就……〞。

analytical machine解析机calculating machine计算机universal machine万能工作机Reading课文学习WHO AM I?我是谁？Over time I have been changed quite a lot. I began as a calculating machine in France in 1642. Although I was young I could simplify difficult sums. I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage. After I was programmed by an operator who used cards with holes, I could "think" logically and produce an answer quicker than any person. At that time it was considered a technological revolution and the start of my "artificial intelligence". In 1936 my real father, Alan Turing, wrote a book about how I could be made to work as a "universal machine" to solve any difficult mathematical problem. From then on, I grew rapidly both in size and in brainpower. By the 1940s I had grown as large as a room, and I wondered if I would grow any larger. However, this reality also worried my designers. As time went by, I was made smaller. First as a PC (personal computer) and then as a laptop, I have been used in offices and homes since the 1970s.随着时间的推移，我已经发生了很大变化。
