文化拓展

①agrochemicalmanufacturingcompanies：农用化学品制造公司

②ecosystem生态系统该词是由eco+system组合而成，eco-前缀通常表示“经济，生态”之意，如：economy经济；ecology生态学

③geneticallymodifiedorganisms：基因修饰生物

科学家们在不导入外源基因的情况下，通过对生物体本身遗传物质的加工、敲除、屏蔽等方法改变生物体的遗传特性，获得人们希望得到的性状。在此类情形下，没有转入外源基因，严格说就不能再称为转基因，称为“基因修饰”更加合适和全面，因此现在开始用“GeneticallyModifiedOrganisms（简称GMOs）”，即“基因修饰生物”，来代替早期的“TransgenicOrganisms”（转基因）。

④biodiversity：生物多样性。bio-是英语词根，常见意思表达“生命、生物”

如：biologyn.生物学；biochemistryn.生物化学；biophysics

n.生物物理学

⑤ADHD：一般指注意缺陷与多动障碍，俗称多动症。

多动症表现为注意集中时间短暂，注意力易分散，他们常常不能把无关刺激过滤掉，对各种刺激都会产生反应。因此，患者在听课、做作业或做其它事情时，注意力常常难以保持持久，好发愣走神；经常因周围环境中的动静而分心，并东张西望或接话茬；做事往往难以持久，常常一件事未做完，又去做另一件事；难以始终地遵守指令而完成要求完成的任务等。词汇积累核心词汇释义sustainable/səˈsteɪnəbl/
