问题
选择题
To succeed in a scientific experiment _____ .
A．carefulness is need
B．carefulness is one needs
C．one needs to be careful
D．one need being careful
答案
答案：C
要想在科研实验中取得成功……, 显然句子缺少逻辑主语,所以A,B两项排除. one是第三人称单数,所以C,D中显然是C正确. 另外: need后面接动名词主动形式表被动意义,与need后跟不定式被动意义相同.如: The bicycle needs repairing. =" The" bicycle needs to be repaired.
