C.of walking, of falling D.of walking, to fall
应该选哪一个答案呢？
答：选A
解析：该题考查的是be afraid to与be afraid of的用法区别。在解答该题之前，让我们先来了解一下它们的用法与区别：be afraid to do　不敢，胆怯去做某事，是主观上的原因不去做，意为“怕”；
be afraid of doing　担心出现doing的状况、结果。 doing 是客观上造成的，意为“生怕，恐怕”。例如：
She was afraid to step further in grass because she was afraid of being bitten by a snake.
她生怕被蛇咬着，而不敢在草丛中再走一步。
She was afraid to wake her husband.
她不敢去叫醒她丈夫。
She was afraid of waking her husband.
她生怕吵醒她丈夫。
此题的句意为“这个小女孩儿不敢在木桥上走，因为她生怕掉进河里。”由此可知，正确答案为A项。
