正确的表达是：1）All his money have been donated to a charity organization for homeless by him.或者：2）He has donated all of his money to a charity organization for homeless.
首先你要知道the other day表示过去时间。其次，可以看到前面的donated是过去分词，过去分词表示被动和完成。最后，能够判断出来，书已经捐赠了，而且已经被送到农村的学生手中，用过去完成时态had been sent。be said to do 是被动，表示据说。 加上完成时态，那就是 be said to have been sent（不定式to后用动词原形）
