1.Millins watched that first lunar landing n black and white televisin sets,their hearts in their muths,aware f hw arduus and hazardus an undertaking it was,and f the many things that culd g wrng.翻译:数以百万计的人在黑白电视机上观看了第一次登月,他们的心提到了嗓子眼儿,意识到这是一项多么艰巨和危险的任务,也意识到许多可能会出错的事情。分析:本句的主干部分是Millins watched that first lunar landing n black and white televisin sets,their hearts in their muths是独立主格结构,aware f hw arduus and hazardus an undertaking it was,and f the many things that culd g wrng这部分是形容词短语作状语,来说明主语的状态。and 是表示并列关系,而且后面省略了形容词aware。思考:如果用来修饰句子的谓语动词或整个句子,则应用副词作状语。
2.With Armstrng's nw famus wrds “That's ne small step fr man,ne giant leap fr mankind”,what had nce been cnsidered impssible had nw been achieved.翻译:随着阿姆斯特朗那句至今仍然著名的话“这是个人的一小步,却是人类的一大步”,曾经被认为不可能的事情现在已经做到了。分析:what双重身份,引导主语从句,并在主语从句中做cnsider的宾语。思考:能否脱口而出一个例句?After what seemed a very lng time,I pened my eyes and fund myself in bed.
Para. 2 Space travel fllwing the Mn landings
3. Fllwing the Mn landings, space travel rapidly became unexceptinal t the public, as innvatins succeeded each ther. By the early 1980s, the great rckets previusly used in the American space prgramme had been replaced by the space shuttle. 翻译:登月后,随着新事物接连出现,宇宙航行迅速成为公众眼中的寻常之事。20世纪80年代早期,美国太空计划中使用的大型火箭已经被航天飞机所代替。分析:fllwing现在分词作状语,属于非谓语的一种。思考非谓语动词的解题思路:一是判断考点:找到句子的谓语动词,另外句中没有出现连词,再出现一个动词必然是非谓语动词;二是分析非谓语动词和其逻辑主语的关系:如果是主动就用v-ing;被动则用v-ed;表将来或目的就用t d 不定式;三是判断非谓语动词和谓语动词之间的关系:非谓语动词发生在主句谓语动词之前则用having dne或者having been dne
Para.2 What was special abut the Challenger launch?
It was special because Christa McAuliffe aged 37, an rdinary teacher and mther, was abut t becme the first civilian in space. 4.Christa hped t cmmunicate a sense f excitement and rekindle interest in the space prgramme.翻译:克丽斯塔希望借此传达她的激动之情.重新燃起人们对太空计划的兴趣。分析:cmmunicate 熟词生义: v.(与某人)交流(信息或消息、意见等);传达,传递(想法、感情、思想等)
5.The wrld went int shck, mst peple having assumed that this space flight wuld be n mre dangerus than travelling in an aerplane. Hw wrng they have been!翻译:全世界都震惊了,大多数人本以为这次太空航行不会比乘飞机旅行更加危险。但是所有人都大错特错了。分析:mst peple……在句中是独立主格结构。思考:n +比较级+than 和 nt + 比较级+ than 分别是什么含义,在文章中出现是否能精准翻译。n +比较级+than 两者都不……nt + 比较级+ than 不比……怎么样
Para.3 &4 Space Shuttle Challenger DISASTER
“ I can remember that day s clearly, watching the take-ff n TV at schl,” said ne student. “ There was an rdinary teacher n the Challenger, and we were all very excited. We didn`t have much patience waiting fr the launch. We had seen the smiling faces f the astrnauts waving t the wrld as they stepped int the shuttle. Then, little mre than a minute after take-ff, we saw a strange red and range light in the sky, fllwed by a clud f white smke. The Challenger had explded in mid-air and we all started screaming.”
Para. 5 What was dne in the three years fllwing the disaster?
6. Fllwing the shck f the Challenger disaster,space shuttle flights were suspended fr nearly three years while the cause f the disaster was investigated,and sme f the shuttle’s cmpnents were redesigned.翻译:“挑战者”号令人震惊的灾难发生后,航天飞机航行终止了三年时间,同时调查事故原因,重新设计飞行器的部分零件。分析:fllwing在句中是现在分词作状语。While译为:在……期间。思考:while单词的用法:并列连词,译为“然而”,表示前后对比;从属连词,译为“当…的时候,在……期间”,引导时间状语从句,通常加延续性动词;从属连词,译为“趁着”,引导时间状语从句,常用语谚语:Strike the irn while it is ht.(趁热打铁)从句连词,译为“尽管”,引导让步状语从句,相当于althugh;
7.It has nw been ver 30 years since the lss f Challenger and althugh the lives f its crew were cut tragically shrt,they take their place alngside the ther heres f space explratin,such as Gagarin,Tereshkva,Armstrng and Yang Liwei.翻译:“挑战者”号失事至今已经过去30多年了,虽然机组人员不幸结束了短暂的生命,但他们与卡加林、捷列什科娃、阿姆斯特朗和杨利伟等太空探索英雄并驾齐驱。分析:本句结构比较复杂。It has nw been...和they take their place...是并列句,since引导的是第一个分句的时间状语从句,althugh引导的是第二个分句的让步状语从句。It is/has been+一段时间+since从句(用一般过去时态)...意为“自从……以来……”,since可以做介词,也可做连词。注意:since+过去时间点在句中做时间状语,句子用现在完成时态。Since ancient times calligraphy has played a critical rle in Chinese culture and histry.
