“abide by”：遵守

In recent days, filming short videos with mobile phones has become a common phenomenon on campus. While it can record our wonderful moments, we should also pay attention to some problems. It’s advisable to arrange our time reasonably to avoid affecting studies. Meanwhile, the content should be positive and healthy. Last but not least, we must abide by school regulations. Let’s make good use of this way to enrich our campus life.

That’s all. Thank you!

Kevin, a 12-year-old boy, found himself bored and under the care of his babysitter, Mrs. Crawler. His parents were both away, with his father on military duty and his mother at work. While Mrs. Crawler slept soundly, Kevin tried to occupy himself with homework and occasionally ventured outside. He was a responsible boy, thanks to his father’s teachings about honor, bravery, and being a real man.

One day,Kevin noticed a strange man entering the house of their neighbors, the Alexanders. Alarmed, he immediately called the police, but they took longer than expected to arrive. Worried that the thief might escape, Kevin decided to take matters into his own hands. He grabbed a stick from the yard and confronted the thief inside the house.

To his surprise, the thief didn’t threatenKevin or react aggressively. Instead, he pleaded with Kevin to let him finish what he was doing. He claimed that the house was once his home, and he needed to retrieve something. Confused, Kevin hesitated, unsure of whether to believe him.

However, the sound of a police car approaching startled the thief, and he made a hasty escape through a window.Kevin followed him, but the thief managed to flee before the police could apprehend him. Despite his actions, Kevin couldn’t shake the feeling that there was more to the story than meets the eye.

Later that evening,Kevin’s father commended his son for his bravery and honored him during dinner. Kevin’s mother, though appreciative of his courage, expressed concern about the dangers he had faced. She reminded Kevin that sometimes thieves can be armed and that it was best to leave such situations to the police.

Reflecting on his mother’s words,Kevin began to doubt his actions. He couldn’t help but wonder if he had made the right decision. He shared his thoughts with his friend Elias, who suggested they investigate further by opening the floorboard the thief had been attempting to access.

The next day,Kevin and Elias returned to the Alexanders’ house. With a key Elias had, they managed to lift the floorboard and discovered a vintage watch wrapped in a red handkerchief, along with some cash. Confused by the significance of the items, they decided to return them to their rightful owner.

Kevin’s father accompanied him to the police station to inquire about the man who had been arrested. The police officers listened to Kevin’s account and the man’s claims about the items beneath the floorboard. To their surprise, the man could provide evidence that the items belonged to him, including the initials on the watch.

Afterward,Kevin and his father left the items with the police as part of the investigation. Days later, there was a knock at their door. Kevin’s mother opened it to find the man, Albert, standing before them. Albert explained that he had been released by the police after proving his ownership of the items.

Albert expressed his gratitude toKevin for his bravery and for setting things right. He acknowledged Kevin’s courage in trying to catch the thief and his sense of honor in wanting to return the stolen items. As a token of his appreciation, Albert gifted Kevin a pair of water guns, reminiscing about his own fond childhood memories of playing with them.

Kevin and Elias couldn’t contain their excitement. They spent the summer having the best time with their new water guns. Kevin’s parents even joined in on the fun, harkening back to a time when children played outside and created their own adventures.

In the end,Kevin learned valuable lessons about trust, compassion, and the complexities of the world. His actions may not have led to the outcome he initially expected, but they had set in motion a chain of events that ultimately revealed the truth and brought gratitude from a stranger.

文 ，一个12岁的男孩，发现自己很无聊，在保姆克劳勒太太的照顾下。他的父母都不在，父亲在服兵役，母亲在工作。当克劳勒太太熟睡时， 凯文 试图用作业来打发时间，偶尔也会冒险外出。他是一个负责任的男孩，这要归功于他父亲关于荣誉、勇敢和成为真正男人的教导。

一天， 凯文 注意到一个陌生男子进入他们邻居亚历山大家的房子。惊慌之下，他立即报了警，但他们比预期花了更长时间才赶到。担心小偷可能会逃跑， 凯文 决定自己动手。他从院子里抓起一根棍子，与屋内的小偷对峙。

令他惊讶的是，小偷没有威胁 凯文 也没有做出过激反应。相反，他恳求 凯文 让他完成他正在做的事情。他声称这栋房子曾经是他的家，他需要找回一些东西。困惑的， 凯文 犹豫了一下，不确定是否要相信他。

然而，一辆警车的接近声惊动了小偷，他匆忙地通过窗户逃走了。凯文 跟了上去，但小偷在警察逮捕他之前设法逃脱了。尽管他的行为， 凯文 无法摆脱一种感觉，即这个故事比表面上看起来的更复杂。

那天晚上晚些时候， 凯文的父亲表扬了他的儿子勇敢，并在晚餐期间为他感到骄傲。凯文的母亲虽然欣赏他的勇气，但对他所面临的危险表示担忧。她提醒凯文 有时小偷可能持有武器，最好让警察来处理这种情况。

回想母亲的话， 凯文 开始怀疑自己的行为。他不禁怀疑自己的决定是否正确。他与朋友伊莱亚斯分享了他的想法，伊莱亚斯建议他们进一步调查，打开小偷试图进入的地板。

第二天， 凯文 和伊莱亚斯回到了亚历山德家的房子。他们用埃利亚斯的一把钥匙撬起地板，发现了一只用红色手帕包着的古董手表，还有一些现金。由于对这些物品的意义感到困惑，他们决定把它们归还给合法的主人。

凯文的父亲陪他去警察局询问被逮捕的人。警察听取了凯文 的描述以及该男子对地板下方物品的声称。令他们惊讶的是，这名男子可以提供证据证明这些物品属于他，包括手表上的首字母。

之后， 凯文 和他的父亲将物品交给警方作为调查的一部分。几天后，有人敲了他们的门。凯文 的母亲打开门，发现那个男人，阿尔伯特，站在他们面前。阿尔伯特解释说，在证明了他对这些物品的所有权后，他被警方释放。

阿尔伯特向 凯文 表达了他的感激之情，因为他勇敢地解决了问题。他承认了 凯文在试图抓住小偷时的勇气，以及他想要归还被盗物品的荣誉感。作为表达感激的礼物，阿尔伯特送给了凯文 一对水枪，回忆起自己童年与它们玩耍的美好回忆。

凯文 和伊莱亚斯抑制不住自己的兴奋。他们整个夏天都在用他们的新水枪玩得最开心。凯文 的父母甚至加入了这个乐趣，回想起孩子们在户外玩耍并创造自己的冒险时光。

最终， 凯文 学会了关于信任、同情和世界的复杂性的宝贵教训。他的行动可能没有带来他最初期望的结果，但它们启动了一系列事件，最终揭示了真相，并从一个陌生人那里获得了感激之情。
