On the night of 2 November, staff at supermarkets in several European countries found something strange: their freezers were warm. In shops in Sweden, Belgium, Luxembourg, Ireland and Estonia, the temperature inside some cold rooms had been set to 50 degrees Celsius. Food that should have stayed near minus eighteen degrees was ruined by morning. No one had touched the machines. The order had come from the internet.
The first cases appeared in France in October. Hackers reached hundreds of supermarket cooling systems and pushed the temperature up, destroying fresh food and, in some places, starting fires. Last week the same thing happened again, and this time it crossed borders in a single night. Carrefour said fifteen of its 700 Belgian stores were affected. Irish chain SuperValu reported thirteen shops. In Sweden, one store noticed the attack at 2 a.m. but only found it at 5:30 a.m.
How is this possible? Modern fridges are no longer simple machines. They are computers with a cooling function. A shop can check temperatures, save energy and call a repair team from an office miles away, because every unit is connected to the network. That convenience has a price. If the connection is weak, a stranger who finds the right password can become the person in charge of the fridge.
The damage is easy to imagine. A supermarket cannot sell food that spent hours at 50 degrees. Whole shelves go into the bin, and customers who arrive in the morning find empty spaces. Sweden has raised the case to a national level, Belgium has opened a criminal investigation, and the European Union said such attacks disturb daily life, not just business.
The lesson is simple. A locked door is useless if the key hangs outside, and a clever machine is useless if nobody guards its connection. Before we connect everything in our homes and streets to the internet, we should first ask who is allowed to give the orders.

长难句拆解 · 分词短语作定语
原句：Food that should have stayed near minus eighteen degrees was ruined by morning. 主干：Food was ruined.（食物被毁了） 从句：that should have stayed near minus eighteen degrees —— that 引导定语从句修饰 Food。 语法定点：should have stayed 是「情态动词 + have done」，表示「本应如此却没有」，暗含结果与预期相反。 直译：本应待在零下十八度左右的食物，到早上已经被毁掉了。
长难句拆解 · 原因状语从句 + 条件从句嵌套
原句：A shop can check temperatures, save energy and call a repair team from an office miles away, because every unit is connected to the network. 主干：A shop can check, save and call.（三个动词共用一个主语 can） because 引导原因状语从句：because every unit is connected to the network。 语法定点：from an office miles away 中 miles away 是名词短语后置修饰 office，等于 an office that is miles away。 直译：一家店可以查看温度、节省电力，还可以从几英里外的办公室叫来维修队，因为每一台设备都连着网络。

雅思阅读最爱把原文换个说法再出题，下面每组左边是原文表达，右边是常见替换，先遮住右边自测。
- were warm → were not cold at all / had heated up（描述设备状态，比 cold 更强调异常）
- ruined by morning → destroyed overnight / spoilt before sunrise（时间 + 结果，常见于事故叙述）
- pushed the temperature up → raised the temperature / turned the heat on（动词短语替换，说明人为操作）
- crossed borders → spread to other countries / went international（描述事件范围扩大）
- That convenience has a price → there is a cost to such ease / ease comes at a cost（观点句，写作中用来转折）
- empty spaces → gaps on the shelves / missing products（间接描述后果，比 no food 更具体）
- guards its connection → protects its network link / keeps the gateway safe（网络安全类高频替换）

- True / False / Not Given: The people who attacked the freezers had to enter the shops in person.
- 简答：According to the passage, what temperature was set inside some of the cold rooms?
- 选词填空（选一个）：Sweden has ____ the case to a national level. (raised / refused / rebuilt)
参考答案与解析
- FALSE。第二段和第一段都说指令来自网络（The order had come from the internet），无人碰过机器，与「亲自进店」相反。典型偷换：把「远程操控」改成「到场动手」。
- 50 degrees Celsius（摄氏 50 度）。答案在第一段 set to 50 degrees Celsius；干扰项是 minus eighteen degrees，那是食物本应保持的温度，不是被设定的温度。
- raised。第四段 Sweden has raised the case to a national level。refused 与文意相反，rebuilt 属形近干扰，原文没有重建案件之说。
中文译文
11 月 2 日夜间，几个欧洲国家的超市员工发现了怪事：自家的冰柜是温的。在瑞典、比利时、卢森堡、爱尔兰和爱沙尼亚的一些门店，部分冷库里的温度被设成了 50 摄氏度。本该保持在零下十八度左右的食物，到早上已经坏了。没有人碰过这些机器，指令是从网络上来的。
第一批案例出现在十月的法国。黑客攻进了数百家超市的制冷系统，把温度往上推，毁掉了生鲜食品，有些地方还起了火。上周同样的事情再次发生，这一次一夜之间就跨过了国界。家乐福称其比利时的七百家门店中有十五家中招；爱尔兰连锁超市报告十三家门店受影响。在瑞典，一家店凌晨两点就遭到攻击，直到五点半才发现。
这怎么可能？现代冰柜早已不是简单的机器，而是带制冷功能的电脑。门店可以查看温度、节省电力，还能从几英里外的办公室叫来维修队，因为每一台设备都连着网络。这种便利是有代价的。如果连接不够牢靠，一个找到正确密码的陌生人，就能成为决定冰柜温度的那个人。
损失不难想象。在 50 度里待了几个小时的食物，超市是卖不出去的。整排货架的东西被扔进垃圾桶，早上进店的顾客只看到空空的货架。瑞典已将此案提升到国家级，比利时启动了刑事调查，欧盟表示这类攻击扰乱的不只是企业运营，还有民众的日常生活。
道理很简单。锁上的门，如果钥匙挂在门外面，就毫无用处；再聪明的机器，如果没人看守它的网络连接，也毫无用处。在我们把家里和街上的一切都连上网络之前，该先问一句：谁才有权下达指令。
