書本的朗讀語音很charming的磁性英音~~~大家可以好好學(xué)著模仿哦~~~?。?
因?yàn)樵鵀槊绹怂鶎?單詞采用美式拼法,不抄全文，也不用寫序號。答完一空換行繼續(xù)下一空作答。文中需聽寫單詞或詞組用[-No-]表示，句子用[---No---]表示。請邊聽寫邊理解文意，根據(jù)下面的TIPS訓(xùn)練聽寫。這樣可以提高聽力準(zhǔn)確度，并為訓(xùn)練聽譯打下基礎(chǔ)哦~~~
TIPS聽寫訓(xùn)練點(diǎn)：單詞拼寫，時(shí)態(tài)，單復(fù)數(shù)，連讀，長難句（請邊聽邊用符號先記下內(nèi)容，然后自己回頭組織語句，最后校對，不要逐字逐句聽寫）

One learned body, the Askesian Society, was for a time devoted to little else.
robust
Goodness knows how many tens of thousands of people suffered unnecessary agonies under the surgeon's knife because no one thought of the gas's most obvious practical application.
bearings
severely
Chemistry was, generally speaking, a science for businesspeople, for those who worked with coal and potash and dyes, and not gentlemen, who tended to be drawn to geology, natural history, and physics.
It is perhaps telling that one of the most important observations of the century, Brownian motion, which established the active nature of molecules, was made not by a chemist but by a Scottish botanist, Robert Brown.
namely
19世紀(jì)初，英國開始風(fēng)行吸入一氧化二氮，或稱笑氣，因?yàn)橛腥税l(fā)現(xiàn)，使用這種氣體會"給人一種高度的快感和刺激"。在隨后的半個世紀(jì)里，它成了年輕人使用的一種高檔毒品。有個名叫阿斯克協(xié)會的學(xué)術(shù)團(tuán)體一度不再致力于別的事情，專場舉辦"笑氣晚會"，志愿者可以在那里狠狠吸上一口，提提精神，然后以搖搖擺擺的滑稽姿態(tài)逗樂觀眾。
直到1846年，才有人有時(shí)間為一氧化二氮找到了一條實(shí)用途徑：用做麻醉藥。事情是明擺著的，過去怎么誰也沒有想到，害得天知道有多少萬人在外科醫(yī)生的刀下吃了不必要的苦頭。
我提這一點(diǎn)是為了說明，在18世紀(jì)得到如此發(fā)展的化學(xué)，在19世紀(jì)的頭幾十年里有點(diǎn)兒失去方向，就像地質(zhì)學(xué)在20世紀(jì)頭幾十年里的情況一樣。部分原因跟儀器的局限性有關(guān)系--比如，直到那個世紀(jì)末葉才有了離心機(jī)，極大地限制了許多種類的實(shí)驗(yàn)工作。還有部分原因是社會?？偟膩碚f，化學(xué)是商人的科學(xué)，是與煤炭、鉀堿和染料打交道的人的科學(xué)，不是紳士的科學(xué)。紳士階層往往對地質(zhì)學(xué)、自然史和物理學(xué)感興趣。（與英國相比，歐洲大陸的情況有點(diǎn)兒不一樣，但僅僅是有點(diǎn)兒。）有一件事興許能說明問題。那個世紀(jì)最重要的一次觀察，即確定分子運(yùn)動性質(zhì)的布朗運(yùn)動，不是化學(xué)家做的，而是蘇格蘭植物學(xué)家羅伯特?布朗做的。（布朗在1827年注意到，懸在水里的花粉微粒永遠(yuǎn)處于運(yùn)動狀態(tài)，無論時(shí)間持續(xù)多久。這樣不停運(yùn)動的原因--即看不見的分子的作用--在很長時(shí)間里是個謎。）
