摘要：It gratified him to think that it was all his work. (想到这都是他的工作，他很高兴。) [牛津高级学者辞典]

动词gratify是正式用语，含义为satisfy, 即“让.....满意/高兴”

【例句1】It gratified him to think that it was all his work. (想到这都是他的工作，他很高兴。) [牛津高级学者辞典]

被动式更为常见，如

【例句1】I was gratified by their invitation. (我对他们的邀请感到满意。)[牛津高级学者辞典]

【例句2】We were gratified by the response to our appeal. (我们对我们的呼吁得到回应感到满意。)[剑桥高级学者辞典]

【例句3】Mr. Dambar was gratified by his response. (Dambar先生对他的回答感到满意。) [柯林斯高级学者辞典]

【例句4】He was gratified by Lucy's response. （他对露西的回答感到满意。） [朗文当代英语词典]

之所以用被动式，可能是因为“满意的供给侧”往往是事(不是人)，因而表达相对长一些，用by放在后面，句子结构更清晰(适合公共场合或正式场合表达)。

gratify也有“满足了[好奇心|需求|期望]”之义(供给者是人)，如

【例句5】We gratified our friend's curiosity. （我们满足了朋友的好奇心。）[柯林斯高级学者辞典]

【例句6】She did not propose to gratify Gloria's curiosity any further. (她不打算再满足格洛丽亚的好奇心了。) [朗文当代英语词典]

【例句7】He only gave his consent in order to gratify her wishes. (他只是为了满足她的愿望才同意的。) [牛津高级学者辞典]

【例句8】Every whim will be gratified. (每一个突发奇想都会得到满足。) [柯林斯高级学者辞典]

过去分词gratified也固化为形容词，典型用法be gratified to see/hear/learn/find(感知动词)， 如

【例句9】He was gratified to hear that his idea had been confirmed. (他很高兴听到他的想法得到了证实。)[柯林斯高级学者辞典]

【例句10】He was gratified to see how well his students had done. （他很高兴看到他的学生们做得这么好。）[剑桥高级学者辞典]

【例句11】John was gratified to see the improvement in his mother’s health. (约翰很高兴看到他母亲的健康状况有所改善。) [朗文当代英语词典]

【例句12】She was gratified to find that they had followed her advice. (她很高兴地发现他们听从了她的建议。) [牛津高级学者辞典]

也可以接that从句和at短语，如

【例句13】They were gratified that America kept its promise. (他们对美国信守诺言感到满意。) [柯林斯高级学者辞典]

【例句14】We were extremely gratified at the number of people who supported us. （我们对支持我们的人数感到非常满意。）[牛津高级学者辞典]

带有by的被动式【例句1】到【例句4】强调动作，而形容词gratifed偏重主体的心理状态。
