Or, have you ever forgotten to switch off the TV or computer? These kinds of things happen to us all the time, waste resources, and can sometimes lead to problems. However, in the not-too-distant future, we will be living in smart homes that will lock the door for us when we are away and remember to switch off the TV when we forget. These smart homes will keep us secure, save us energy, and provide a more comfortable environment to live in. 【重点单词】 ① switch v. 转换，（用开关）打开/关掉；n. 开关，转换器。课文中 switch off the TV 意为“关掉电视”。注意 switch 作动词时常与介词 on/off 搭配。 ② secure adj. 安全的，牢靠的；v. 保护，使安全。课文 keep us secure = 保护我们的安全。派生词：security n. 安全（安全感）；insecure adj. 不安全的。 ③ distant adj. 遥远的，久远的。课文 not-too-distant future = 不远的将来。派生词：distance n. 距离。 【重点短语】 ● switch off/on 关掉/打开（电器）。近义：turn off/on。 ● lead to 导致，通向。如：His laziness led to his failure. 注意 to 为介词，后接名词或动名词。 ● all the time 一直，总是。 ● in the not-too-distant future 在不远的将来。复合形容词作定语。 【重要句型】 ● 定语从句：…we will be living in smart homes that will lock the door for us when we are away… 关系代词 that 指代先行词 smart homes，在从句中作主语。when we are away 和 when we forget 均为时间状语从句，嵌套在定语从句内部。 ● 将来进行时：we will be living in smart homes — 表示“将来某个时候将处于……状态”，比 will live 更有画面感。全文多处使用这一时态（见语法点）。 ● 不定式作后置定语：…a more comfortable environment to live in — 不定式短语 to live in 修饰 environment，注意介词 in 不可省略（live in the environment）。 Para 2 Intelligent Controls Today, we have to use switches for our lights, knobs for our appliances, and remote controls for our TVs and air conditioners. In the future, we will be using advanced technology every day for automatic control of just about everything in our home. The future home will use integrated sensors to tell when you leave home each morning, and then go into an energy-efficient mode all by itself. You will no longer have to think about turning switches on and off yourself. Your home will also learn your daily routine and preferences, so everything will be ready for you when you get home each evening. Your lights will come on the instant you enter the door along with your favourite music or TV programmes, and you will find your dinner already prepared for you. All controls will respond to voice commands, so if you want to change your routine, you just say aloud what you want and the home system will obey. 【重点单词】 ① remote adj. 遥远的，偏僻的；远程的。课文 remote controls = 遥控器（名词短语）。派生词：remotely adv. 遥远地；远程地。 ② automatic adj. 自动的，无意识的。课文 automatic control = 自动控制。派生词：automatically adv. 自动地；反义词 manual adj. 手动的。 ③ integrated adj. 集成的，综合的。课文 integrated sensors = 集成传感器。动词形式：integrate v. 使融合，使整合；integrate A with B = 把A与B整合。 ④ energy-efficient adj. 节能的。课文 energy-efficient mode = 节能模式。构词法：名词+过去分词构成复合形容词。efficient adj. 高效的；efficiency n. 效率。 ⑤ mode n. 模式，方式，状态。课文 go into an energy-efficient mode = 进入节能模式。近义：way / manner / fashion。 ⑥ routine n. 常规，惯例；adj. 日常的，例行的。课文 daily routine = 日常惯例。派生词：routinely adv. 例行地。 ⑦ preference n. 偏爱，偏好。课文 preferences（复数）= 各种偏好。动词形式：prefer v. 更喜欢。短语：have a preference for 偏爱；in preference to 而不是。 ⑧ instant n. 瞬间，片刻；adj. 立即的，速食的。课文 the instant you enter = 你一进门就……。派生词：instantly adv. 立即。 【重点短语】 ● remote control 遥控器；遥控操作。 ● all by itself 自动地，独自地（= automatically / without human help）。 ● no longer 不再（= not…any longer）。如：He no longer smokes. = He doesn't smoke any longer. ● daily routine 日常作息，日常惯例。 ● along with 和……一起；以及，就近原则。 ● respond to 响应，回应；对……做出反应。近义：react to。 ● voice commands 语音指令。 【重要句型】 ● the instant 引导时间状语从句：Your lights will come on the instant you enter the door… 这里 the instant（that）= as soon as，意为“一……就……”。同类结构还有：the moment / the minute / the second / immediately / directly / instantly 引导从句。这是高考高频考点。 ● find + 宾语 + 宾补：you will find your dinner already prepared for you — prepared 为过去分词作宾语补足语，表示被动完成。类似结构：have sth. done / get sth. done。 ● what 引导宾语从句：you just say aloud what you want — what 在宾语从句中作 want 的宾语，意为“……的事物”。 ● so 引导结果状语从句：…so everything will be ready for you… / …so if you want to change your routine… 注意第二句中 so 后面又嵌套了 if 条件状语从句。 Para 3 Regular Health Checks In addition, your smart home will be monitoring your health for you every day. Your bed, for example, will record how well you sleep every night. It will also be checking your body weight. If you start to have sleep or weight problems, it will send a warning to your phone. It will also give you suggestions on a healthier diet and how to sleep better. Smart toilets will be keeping constant track of your health as well. They can warn you early on if there is something abnormal or if you have a critical illness, such as cancer, and potentially save your life. 【重点单词】 ① monitor v. 监视，监测；n. 班长；监视器。课文 will be monitoring your health = 将持续监测你的健康。 ② constant adj. 持续的，不断的；恒定的。课文 keeping constant track of = 持续跟踪。派生词：constantly adv. 不断地，经常地。 ③ abnormal adj. 异常的，不正常的。课文 something abnormal = 异常情况。反义：normal adj. 正常的；前缀 ab- 表示“偏离、离开”。派生词：abnormally adv. 异常地。 ④ critical adj. 关键的；批评的；危急的。课文 a critical illness = 危重疾病。派生词：criticism n. 批评；criticize v. 批评；critic n. 批评家。短语：be critical of 对……持批评态度。 ⑤ cancer n. 癌症。课文 such as cancer = 例如癌症。 ⑥ potentially adv. 潜在地，可能地。课文 potentially save your life = 可能救你一命。形容词形式：potential adj. 潜在的；n. 潜力。短语：have the potential to do sth. 有做某事的潜力。 【重点短语】 ● in addition 此外，另外（= besides / furthermore）。注意其后常接逗号。 ● keep track of 记录，跟踪，掌握……的动向。课文 keeping constant track of = 持续跟踪。反义短语：lose track of 与……失去联系。 ● warn sb. of / about sth. 警告某人某事。课文 warn you early on = 提前警告你。 ● such as 例如（用于举例，后接名词或动名词）。 【重要句型】 ● 疑问词引导宾语从句：…will record how well you sleep every night — how well 引导宾语从句，注意用陈述语序（you sleep，而非 do you sleep）。 ● if 引导条件状语从句（两个并列）：…if there is something abnormal or if you have a critical illness… 两个 if 从句由 or 连接，共用主句 They can warn… and potentially save… Para 4 No More Disasters Smart homes will be able to prevent serious damage from accidents. For example, if a water pipe starts leaking, or if there is a short in the electrical wiring, your smart home will detect it and provide you with the relevant information. This way, you will be able to fix the problem before your home becomes flooded or catches fire. 【重点单词】 ① leak v. 漏，泄漏；n. 漏洞，泄漏。课文 a water pipe starts leaking = 水管开始漏水。 ② detect v. 发现，探测，检测。课文 your smart home will detect it = 智能家居会检测到它。派生词：detection n. 探测；detective n. 侦探。 ③ relevant adj. 相关的，切题的。课文 the relevant information = 相关信息。反义：irrelevant adj. 不相关的。短语：be relevant to 与……相关。 【重点短语】 ● prevent…from… 阻止……发生（= stop…from… / keep…from…）。课文 prevent serious damage from accidents = 防止事故造成的严重损害。 ● provide sb. with sth. 向某人提供某物（= provide sth. for sb.）。 ● catch fire 着火，失火（表示动作；be on fire 表示状态）。 ● This way 这样，通过这种方式。 【重要句型】 ● before 引导时间状语从句：…you will be able to fix the problem before your home becomes flooded or catches fire. before 在此处意为“才，就……来得及”，强调在坏结果发生之前采取行动。 ● 并列谓语：your smart home will detect it and provide you with… — detect 和 provide 并列，共用 will。 Para 5 结尾段 This smart technology is not a fantasy. Many of these new innovations are already available and being used in some homes. In this sense, the home of tomorrow is already the home of today.
