首先理通整个句子:有些人仍然对这个结果持有观望态度,因为还没有发现被动吸烟和癌症有直接因果关系的证据.
这里remains to be seen 对应的就是中文里“还没有发现”
还没有发现是以人为主语
而这个英文句子中那个“被动吸烟与癌症有直接因果关系”是主语,是“被发现、被显示”所以用被动语态 选B
所以做题时,最先要做的猜出句子想要表达的意思
只有答案B在这个句子里有意义。
答案A表示已经发生的行为
答案C是答案A的被动型态
答案D不可以与remain合用(中国老师说不合乎语法,外国人说没有人这样说话)。
有些人以谨慎的态度看待这些发现指出,一个之间的因果关系,被动吸烟和癌症仍然是____
A来显示.
B要显示
remain to be done
固定搭配
只能选择B,因为其他都不合语法
