选项分析:
文章前三段提及 Light Microscopes。
文章第四段至第六段提及 Electron Microscopes。
文章最后一段前半部分讲 Electron Microscopes,后半部分讲 Light Microscopes。
A 选项属于 Light Microscopes。Their lenses are made of glass 对应第一段的第三句:Glass lenses in the microscope bend the light to magnify the image of the specimen and project the image into the viewer's eye or onto photographic film 以及第六段倒数第二句 However, instead of lenses made of glass, the transmission electron microscope uses electromagnets as lenses, as do all electron microscopes 对比说明 Light Microscope 的透镜是 made of glass。
D 选项属于 Light Microscopes。They are used to study living specimens 对应最后一段倒数第二句 Thus, the light microscope remains a useful tool, especially for studying living cells。
F 选项属于 t Microscopes。They cannot resolve the internal structure of small cells 对应第二段的最后一句 The light microscope cannot resolve detail finer than 0.2 micrometers, about the size of the smallest bacterium; consequently, no matter how many times its image of such a bacterium is magnified, the light microscope cannot show the details of the cell's internal structure。
B 选项属于 Electron Microscopes。They use magnetism to bring images into focus 对应第六段倒数后两句 However, instead of lenses made of glass, the transmission electron microscope uses electromagnets as lenses, as do all electron microscopes. The electromagnets bend the electron beam to magnify and focus an image onto a viewing screen or photographic film。
E 选项属于 Electron Microscopes。They can produce images that appear three-dimensional 对应第五段最后一句 The scanning electron microscope produces images that look three-dimensional。
C 选项说 They were invented in the mid-1800s 文章中关于两种显微镜发明时间没有说。
G 选项说 They can usually resolve details smaller than the size of an atom 第四段的倒数第二句 Only under special conditions can electron microscopes detect individual atoms 因此与原文描述不符。
