SF courier delivery

- [ ] 今天對小張來說，本該是一個平凡的工作日。作為順豐速遞的一名快遞員，送貨上門是他每天的常規任務。那天早上，天氣異常炎熱，烈日炙烤著大地，連空氣中都透著一股窒息的悶熱。小張從早晨開始就一直在不停奔波，送貨的數量也比平時更多。汗水早已濕透了他的制服。

- [ ] 下午三點，小張來到一個偏僻的小區，手裡拿著一個大件包裹，準備送到五樓的住戶家中。這是他今天的第十幾個包裹了。當他敲開門時，一位看起來十分友善的中年大叔微笑著迎接他。看到小張滿頭大汗，他熱情地邀請他進來休息片刻，並遞上一杯冰涼的水。

- [ ] 「你這麼辛苦，喝點水吧，解解渴。」說道。

- [ ] 小張本來想拒絕，因為公司有規定，工作時最好不要隨意接受客人的食物或飲料。然而，連日的高溫與疲勞讓他實在難以抗拒這杯看似普通的涼水。猶豫了幾秒，他還是接過水杯，一口氣喝了下去。

- [ ] 然而，就在他準備道謝並繼續趕路時，異樣感覺突然襲來。他的頭開始暈眩，視線變得模糊，四肢無力，像是突然失去了對自己身體的控制。小張試圖站穩，但腳下一軟，瞬間失去平衡，重重地摔倒在地上。意識在片刻間消失了．．．

- [ ] Today was supposed to be an ordinary working day for Xiao Zhang. As a courier for SF Express, door-to-door delivery is his daily task. That morning, the weather was extremely hot, the sun was scorching the earth, and there was a suffocating heat in the air. Xiao Zhang has been running around non-stop since morning and has delivered more goods than usual. Sweat had soaked his uniform.

- [ ] At three o'clock in the afternoon, Xiao Zhang came to a remote community with a large package in his hand, ready to be delivered to the home of the resident on the fifth floor. This is his tenth package today. When he knocked on the door, a middle-aged man who looked very friendly greeted him with a smile. Seeing that Xiao Zhang was sweating profusely, he warmly invited him to come in to rest for a while and handed him a glass of ice-cold water.

- [ ] "You have worked so hard, drink some water to quench your thirst." He said.

- [ ] Xiao Zhang originally wanted to refuse because the company had regulations that it was best not to accept food or drinks from customers at work. However, the high temperature and fatigue for days made it difficult for him to resist this seemingly ordinary cup of cold water. After hesitating for a few seconds, he took the water glass and drank it in one gulp.

- [ ] However, just as he was about to say thank you and continue on his way, a strange feeling suddenly hit him. His head began to feel dizzy, his vision became blurred, and his limbs became weak, as if he had suddenly lost control of his body. Xiao Zhang tried to stand firm, but his feet weakened, he instantly lost his balance and fell heavily to the ground. Consciousness disappeared in a moment.
