求助英语老师帮我改下这个句子As to whether it is good for testing students by examination as the only reliable method to measure the students level
答
这样改：As to whether it is good to test students by examination, the only reliable method to measure students' level...
或者：As to whether it is good to test students by examination, which is the only reliable method to measure students' level...
显然这不是一个完整句,而是一个由 As to 引出的短语,有状语的功用,因此其后还应该有句子的主要部分.
