问题 All matter is made up of atoms; _______, it is made up of nuclei with electrons whirling around them.
选项 A、that is
B、on the contrary
C、in short
D、on the other hand
答案 A
解析 短语意义辨析。A. that is也就是说，即；B．on the contrary相反地；C. in short简而言之；D．on the other hand另一方面，常与on one hand连用。根据题意和逻辑应选A。句意为：所有的物质都是由原子构成的，也就是说，它是由原子核和围绕着原子核旋转的电子构成的。
