钳型表的工作原理如图所示。当通有交流电的导线从环形铁芯的中间穿过时，与绕在铁芯上的线圈相连的电表指针会发生偏转。由于通过环形铁芯的磁通量与导线中的电流成正比，所以通过偏转角度的大小可以测量导线中的电流。下面关于用一钳型电流表测量某一电流值说法正确的是（  ）

    One day, in an English class, the students are doing their lessons. Their teacher, a young woman, is very happy. She sings with them and then she goes to the blackboard and writes “SMILES” on it.
