By the early 1980s,the great rockets previously used in the American space programme had been replaced by the space shuttle.When the Challenger space shuttle took off on 28 January 1986,the world seemed to have lost its wonder at the amazing achievements of the astronauts involved.But this was going to be no ordinary excursion,and millions of people tuned in to witness the take-off on TV.It was special because Christa McAuliffe aged 37,an ordinary teacher and mother,was about to become the first civilian in space.She planned to give two 15-minute lessons from orbit:the first to demonstrate the controls of the spacecraft and explain how gravity worked,and the second to describe the objectives of the Challenger programme. Tragically,she never returned to her classroom as the shuttle exploded just over a minute after taking off in Florida,and all seven astronauts on board were killed.It was the most disastrous space accident ever,and it cast a shadow on people’s hearts. 词汇积累 1.shuttle / tl/ n.航天飞机 2.excursion /Ik sk n/ n.短途旅行 3.civilian /s vIli n/ n.平民 4.demonstrate / dem nstreIt/ vt.证明;论证 5.tragically / tr d Ikli/ adv.悲惨地,不幸地 6.cast /kɑ st/ vt.投射(光、影子等);投,抛 佳句背诵 1.By the early 1980s,the great rockets previously used in the American space programme had been replaced by the space shuttle.(“by+某一时间”作时间状语,主语用完成时) 到20世纪80年代早期,以前在美国太空计划中使用的大型火箭已被航天飞机所代替。 2.It was the most disastrous space accident ever,and it cast a shadow on people’s hearts.(观点表达) 这是有史以来最惨重的太空事故,给人们的心中蒙上了一层阴影。 Period Ⅰ Listening and Speaking & Listening and Talking 重 音 英语重音分为单词重音和句子重音两种。 一、单词重音 英语单词由于音节的数量不一,就出现了读起来有轻有重的现象。一般地,每个单词都有一个音节是重读的,称重读音节,其余的音节不重读,称非重读音节。但有的多音节词,除了一个重读音节之外,还有一个次重读音节。 二、句子重音 在一个句子中,常常只重读一部分单词,其余的单词在句子中却不重读,这些重读的单词就叫作句子重音。 1.功能:体现句子的节奏感和韵律感,突出重点,使听者更容易理解。 2.在句子中需要重读的词 一般来说,在句子中需重读的词都是实词,比如,名词、动词、形容词、副词、数词、代词等。不重读的多为虚词,比如,冠词、连词、介词、感叹词等。 The streets are wide and clean. I am so glad to see you again. 3.虚词需要重读的情况 (1)强调或突出某个虚词或be动词时,应将其重读。 —Are you a student —Yes,I am. (2)介词在句首时往往要重读。 On my way to school,my bike was broken. (3)be动词及助动词和not结合时要重读。 Didn’t I tell you yesterday (4)句子末尾的be动词和助动词一般要重读。 Here you are. ※上文刚出现过的并且重读的单词,第二次提到时一般不再重读。 [即时练] 朗读下面的对话,体会重音变化。 Mary:Is there something wrong,Karen Karen:It’s okay.I’m being silly.
