解答

【问题1】This farm tool needs _.A.repair B.to repair C.repairing D.repairs 【解析】应当选A,repair.这里repair 作为名词,并且它是不可数名词,故排除D选项.如果repair作为动词,此处应用被动语态,即to be repaire...need doing不是也有被动的含义吗？主语是 farm tool，动词时repair，自然要用被动语态。[刚又查了一下，我觉得你说的也对，似乎needs repair 和 needs repairing 放在这里都行。也许是我们对这两种表达方法的细微区别还理解的不够透彻，又或者题目本身出的不够严谨。]
