[求助]大全987的17 题

1.        A patient accusing a doctor of malpractice will find it difficult to prove damage if there is a lack of some other doctor to testify about proper medical procedures.

(A) if there is a lack of some other doctor to testify

(B) unless there will be another doctor to testify

(C) without another doctor’s testimony

(D) should there be no testimony from some other doctor（C）

(E) lacking another doctor to testify

虽然我也选C，但仍有点不明白。请NN讲解一下，如果只从语法角度讲，B,E是否正确

未划线部分 about proper medical procedures

前面应该是一个名词，about是关于其的说明

“testimony about proper medical procedures” 关于正确医学程序的证词

从语法角度上说ABE是不适合的

在yvrv的带动下，我也去查了一下字典，在朗文当代英语词典里只有testify against/for/to和that从句四种用法。
