  夏志清贬抑金瓶梅，推重儒林外史，尺度是写实主义的纯粹度，虽不是一点道理没有，但还是有失偏颇。佛教世界观的渗透，副作用固然有，却并非全无是处，金瓶梅便获益不少。

  　The first impression that the boy Tom gave me was a naughty, mischievous boy, just as what Aunt Polly said. He never lacked the curiosity to explore new places, sometimes even risking his life, which I did not dare to! There were some great adventures of him with Huck or Joe. Huck was an orphan, and Joe was Tom’s classmate. Everybody in the small village knew Tom, mainly for Tom’s—you know kind of gallantry!

  　　I should tell you the adventures. The origin of the attempt was that Tom and Huck was getting curious to the world of outside, and they made an effort to run-away. However, when they were in the graveyard, some people appeared. They were Injun Joe, Huck’s father, named Potter, and a doctor. Tom and Huck quickly hid behind the bush, and they saw them digging the coffins out, probably finding something valuable. They did not realize that what they witnessed was a murder! Tom and Huck were extremely afraid, and they ran away rapidly. On the court, Potter was being accused of the murderer; however, Tom declared that it was Injun Joe who used Potter’s knife to kill the young doctor. On hearing this, Injun Joe broke the glass and ran away! This scared everybody, and Tom’s brother, Sid, said that he always heard Tom mumbling something when he was asleep, and sometimes even shouting. Indeed, the accident was fluttering everybody in the town with fear.

  　　Before, Tom once fell in love with a girl called Lawrence. And he showed off in front of the girl, trying to win the girl’s heart, but Lawrence ignored Tom’s appearance, and it made Tom sad. At present, Tom went for another girl for Becky. Yet, when Becky knew that Tom once loved Lawrence (it was probably childish thoughts)， she refused Tom. Tom got so depressed that he resolutely committed the second escape.

  　　He made contact with Huck and Joe that afternoon, about where to meet, the code words of meeting, and the route, and so on and so forth. Each of them brought some food, and Huck brought some pipes (remind that Huck had no real home, and I had no ideas where he got the things). At midnight, they met at the place, and they took a raft down the river. After drifting for about several hours, they finally reached the destiny. There they lived for about several weeks, and while everybody thought they were drowned, they had a great time. They were no problems of food or water shortages. They promised to be a pirate, and would live there forever.

  　　If you were out from your relatives for a long time, wouldn’t you miss home? It was the same for those children. After several weeks, Joe felt that he missed home very much, and Tom could not seem to stop him. On this, Tom brought Joe and Huck his secret—

  　　On one night, when the rest of the boys fell asleep (of course they slept outside)， Tom crept from the camp, and headed toward the town. He sneaked to his aunt’s room, and hid under the bed, while everybody- Mary (Tom’s sister)， Sid, Aunt Polly and Joe Harper’s mother were having a meeting. There were a lot of tears, about how the boys were killed, and how they would treat the boys if they ever lived again, such things. Tom almost wanted to get out of the bed and hug Aunt Polly, but he couldn’t. At last, everybody went to sleep. Tom went out from the bed, and flew to the camp. That was the secret— that the boys will go to their own funeral!

  　　While the boys were outside, all of the people in the town were discussing about the accidents. The town was immediately covered with a sense of doom. So the funeral was raised. Everybody wore a black suit, and they prayed something along with the priest. Just then, they saw somebody entering the gate, and what they saw was unbelievable. Three young souls came out from their coffins and showed up in front of everybody! The change of the atmosphere was imaginable. Aunt Polly, Joe Harper’s mother, Mary and Sid were astounded to find that Tom came so vivid in front of them, and so Tom and Joe became a hero in the school, even in the town.

  　　The real adventures of Tom were finding the treasures.

  一般来说，要学习短视频拍摄的人，可能不会看这样一本书，因为去B站或者小红书上看摄影UP主的教程，跟着操作，会更直接一些。

  这本书更适合改名叫做《抖音快手短视频拍摄技巧》。书的前半部分的女模特挺好看的。

  书里面介绍了一个拍摄技巧，叫做：“如何制作满屏落叶的特效？”我心里想着，可能是绿幕拍摄鼓风机撒落叶，而后做合成吧？也可能是手机拍摄人撒落叶，而后做画幅的边框裁切。但是书中的答案是：“点击抖音里面的落叶特效。”很可爱，突破常规思维，可以做脱口秀的段子素材。
