Old henryo sat downand watched wangwang played with a friend

題目：

Old henryo sat downand watched wangwang played with a friendly cat哪錯了

解答：

watch wangwang played里played錯了,應爲play或playing
watch等一系列感官動詞如see,hear等等後面加動詞時只有三種形式do(如see sb do是看到了某人做某事的全過程）doIng(see sb doing看見某人正在做）see sb done（看到某人被.）如果watched wangwang played 就是看wangwang被玩
