We started flying around the world，launching⑦ satellites⑧ into orbit⑨ and，at the same time，scientists figured out⑩ how to split the atom，previously thought to be the smallest particle of matter in the universe. 【词汇积累】 ①not to mention更不用说 ②range vt.(在一定范围内)变化，变动n. 范围；界限；一系列；山脉 range from...to...范围从……到…… a wide range of各种各样的 ③microscope/'ma kr sk p/n.显微镜 ④donate/d 'ne t/vi.& vt.捐献(器官)，献(血)；捐赠，捐献 donate to...向……捐赠 donation n.捐赠 make a donation to对……进行捐赠 ⑤correspond/ k r 'sp nd/vi.通信；相一致，符合 correspond with sb与某人通信；相符 ⑥instant/' nst nt/adj.立刻的，马上的 instantly adv.立刻，马上conj.一……就…… ⑦launch/l nt /vt.发射；发动，发起，开始从事 launch an activity/event发起一项活动 ⑧satellite/'s t la t/n.人造卫星；卫星 ⑨orbit/' b t/n.轨道 vi.& vt.沿轨道运行 in orbit在轨道上 go into orbit进入轨道 ⑩figure out解决，想出 同义表达:find out/work out split/spl t/vi.& vt.分割，把……分开；分成(不同部分) split up (把……)分成小组；划分，分解；拆散 particle/'pɑ t k l/n.粒子，质点 Although it is impossible to choose the most important discovery，it is possible to single out a few pioneers of the 20th century.Here are some of them. One of the 20th century's premier scientists was Albert Einstein.In the summer of 1905，this outspoken young man [1]was rocking his one-year-old baby when he was suddenly inspired.Subsequently ，“E＝mc2” was born.It showed [2]how a small piece of mass could produce an unbelievable amount of energy.Einstein then showed in his“theory of relativity ”that not even time，mass or length are constant —they change according to our experience of them. single out挑选(后面常跟介词for或as) outspoken/a t'sp k n/adj.坦率的，直言不讳的 subsequently/'s bs kw ntli/adv.后来，随后 relativity/ rel 't v ti/n.相对性 theory of relativity相对论 constant/'k nst nt/adj.恒久不变的；持续不断的，经常发生的n.常量，恒量 constantly adv.时常地，不断地 同义表达:regularly/frequently [1]此处为“be doing...when...”句型，意为“正在做……，这时(突然)……”。 [2]此处为how引导的宾语从句，how在从句中作状语。 In 1928，another important finding was made by biologist Alexander Fleming.Before he went on holiday，Fleming left a dish of bacteria i ... ...
