上进入太空的第一人。

五、“续写”片段一一在背诵中品悟如何写靓写美

心理或动作描写之“惊呆与轻松”

Silentlyandsecretly,Islippedintotheyardoftheoldlady.Ilookedaround

andtherewasnothingbutsilence.Holdingmybreath,IgottheenvelopeIdidn't

signjammedinherdoor.AsImademywayout,thestonewhichhadhunginmyheart

sparklingstarssmilingtome.Ievenlookedforwardtotomorrow'sarrival.

悄悄地溜进了老太太的院子,我环顾四周,周围一片寂静。我屏住呼吸,把我没有签名

的信封卡到了她的门上。当我走出去的时候,悬在我心上三个星期的石头终于不见了。我如

释重负地坐在地上,凝视着向我微笑的闪闪发光的星星。我甚至期待着明天的到来。

[点评]本段用"silentlyandsecretly,siipinto,holdmybreathw等来表达作

者紧张的心理;用“...thestonewhichhadhunginmyheartforthreeweekswas

eventuallygone,thesparklingstarssmilingtome”来表达作者如释重负的心理,这

里用“stone”比喻“压力”,"smiling”是拟人用法,更形象生动地突出了作者压力过后

的轻松。

topeople'sshort-termandlong-termproblems.(总括了太空探索的益处,表明太空探

索应该继续下去这一观点)

由教材学写法

1.学亮点词汇

第一段中的shallow形象地描述了一些人对太空探索的肤浅的、片面的认知。第二段中

用makeadifference写太空探索的影响,用directly一词强调其在绕地卫星方面的积极

贡献,段尾用asaresult引出本段主题。第三段中的promote,improvement,benefit,

advanced等词是描述科技领域的积极影响时的常用词。

2.学高级句式

句❶中which引导定语从句,修饰先行词view,解释了为什么说这一观点是肤浅的。

句❷是一个主从复合句,句子用Inorderto引出目的状语,that引导定语从句,修

饰先行词planets,语言精练地表达了科学家们正在努力寻找其他行星是因为它们有可能成

为我们的新家园,以便满足地球上快速增长的人口需求。

3.学行文逻辑

本文为“总一分一总”的结构。文章先是介绍了人们对太空探索存在的争议性看法,

然后给出自己的观点,进而从三个方面对其进行论证、阐述。文章最后重申了对这一论点的

支持态度。整篇文章用词严谨、逻辑缜密、论证清晰,令人信服。
