It is difficult to ________ the sample that is on the slide unless the microscope is adjusted properly.
A.overlook
B.discern
C.disclaim
D.distract请帮忙给出正确答案和分析,谢谢!

参考答案

正确答案:B
解析:本题要分清三个前缀为dis-动词的意义。B.discern辨别,识别,认出;C;disclaim否认,放弃,拒绝;D.distract转移注意力,分散精力。它们在意义上没有共同之处。A.overlook忽略,忽视。B符合题意要求。句意为:如果不把显微镜调试好的话,就很难分辨切片上的样品。
