Some of this will be captured by the objective lens and, because its wavelength is greater than 400 nm, will not be reflected by the dichroic mirror but will instead pass through (Lines 20-22) 某些（蓝）光将被物镜捕获，而且因其波长大于400nm，会直接通过二色分光镜，而不会被反射。objective lens-物镜。because its wavelength is greater than 400 nm是起着补充说明的插入语。阅读时可通过其两端的逗号识别，速读时可跳过。 Notes 4. nuclei(Line 26): nucleus的复数形式，表示细胞核。类似的名词还有radius, stimulus, focus，它们的复数形式分别是radii, stimuli, fuci. 5. the antibodies purified (Lines 35-36): 抗体被纯化。此处省略了谓语动词is。 6. The antibodies can then be labeled by attaching a fluorescent dye (Line 36)：注意attaching而未采用being attached to，因为by attaching只表述一种方式和途径，不强调具体的行动。 Notes 7. Images c and d show the same field of brain cells but with the excitation filter, dichroic mirror, and emission filter changed so as to reveal in c a protein called ELAV that is found only in nerve cells; then in d an intermediate filament protein (page 000) found only in glial cells.(Lines 37-40) c和d两幅图显示了脑细胞的相同区域，但激发过滤片、二向色分光镜片以及发生过滤片有不同，以便在c图中可显示只在神经细胞中才有的、被称为ELAV的蛋白质；在d图中可显示只在神经胶质细胞中才有的中间丝蛋白。 8.See the CBASC website for an image of all three signals in color and superimposed (Lines 46-47): 所有三种信号的彩色叠加图可参看CBASC网站。句尾可认为省略了manner之类的词。 9. excess：过量的，超出量，过度；excessive：过度的。 10. 介词搭配：binds _____ ELAV， the antibody ____ the chemical of interest, they are illuminated ____ light Notes Grammar in sciences——英语中句子成分的省略(I) 1. 并列句中的省略 在and连接的句子或类似句子后面的分句中与前面分句相同的部分可以省去。凡是发现and之后是“乱七八糟”时就要想到可能某些成分被省去了。只有在前后两个分句的句型相同时才会有省略现象出现，所以一定要根据前
