135, B-22

As recently as 1950, tuberculosis was never curable unless sequestered in sanitariums; today, the drug Isoniazid has made such treatment obsolete.

(A) unless sequestered

(B) without sequestering

(C) without being sequestered

(D) unless it was sequestered

(E) unless patients were sequestered

A) unless (tuberculosis )sequestered意思错。
B)( tuberculosis) sequestering也错。
C) being sequestered同A意思错。
D) it was sequestered同上意思错。
E) correct.

哪位nn可以解释一下这个句子么～～偶读半天都不明白在说什么

对于这里偶想加上一句

语法点中有：介词+分词形式在句中或句尾逻辑主语为句子主语或所修饰的动作的主语，这里句子主语为tuberculosis，所以A B C错

D代词指代有问题

所以。。。

其实同LZ所说的是一样的呵呵
