我认为题目本身所表达的陈述句并不准确,very wrong带有中式英语Chinglish 的色彩。
答案使用首先应该是过去式,然后要使用完成时态。
The methods had proved to be very wrong
出题的都用被动的,谁管我们做题的,坚决用were
在空白处填were
可以用的,你记错了
were
prove的用法如下:
1. 用作连系动词,意为“证明是,结果是,被发现是”,不用于被动语态,后常接形容词、名词、不定式作表语。例如:
The medicine proved satisfactory. 结果证明这种药的疗效令人满意。
She proved a very strict teacher. 结果证明她是一位非常严格的老师。
She may prove to be the most suitable person for the job. 结果证明她可能是最适合干这项工作的人.
2. prove还可用作及物动词,意为“证明,证实”,主要用于下列句型:
(1)prove + 名词或代词。如:
He did some experiments to prove his theory. 他做了一些实验来证明他的理论。
You’re wrong, and I can prove it. 你错了,我能证明。
The strength of China’s economy will be further proved. 中国的经济实力将被进一步证实。
(2) prove+宾语+宾语补足语,作宾语补足语的通常有形容词、名词、动词不定式等。to be通常可以省略。如:
Again history proved him (to be) wrong. 历史再次证明他错了。
This just proves what I have been saying for some time. 这恰好证实了我长久以来所说的。
(3)prove + 宾语从句。如:
Can you prove where you were on May 10th? 你能证实五月十日你在什么地方吗?
The doctor's tests proved that Black was in good health. 医生的检查证明了布莱克身体健康。
