Study of the Text and language points1. something thats only possible on a Hollywood set. 此处的set 是指“（电影）场地，（戏剧）舞台”，即a stage or other place where a film or television program is made or where a play is performed。 然而，这里的a Hollywood set 可以理解成“好莱坞电影”。2.invasive: a. 侵入的，侵袭的【拓展】invade: v. 侵入，侵袭 invasion: n. 侵犯，侵略e.g. We found invasive cancer during the examination. At that time, the country was unable to resist the foreign invasion.3. the strangest hacks that show where the future is headed. 此处的head 为不及物动词，意为“朝行进”（go in a particular direction）， 再如：He decided to head for home quickly.4. vulnerability: n. 脆弱性，易伤性 【拓展】vulnerable: a. 脆弱的，易受伤害的e.g. In cases of food poisoning, young children are especially vulnerable.5. how to unlock a car and start it just by texting. 此处的text 作动词，意为“发短信”（send a written message to sb. using a mobile phone）。6.And back in 2010, a fired auto center employee hacked into 100 cars in Texas, causing them to honk uncontrollably before he remotely disabled them.1) auto center: a particular place where cars are designed, made, sold or repaired 汽车中心2) hack into: 非法侵入（他人的计算机系统）e.g. He tries to hack into the companys computers.3) 该句中的现在分词结构作结果状语，画线部分的字面意思为“在使汽车失灵前，让喇叭不加控制地鸣响”，但是可灵活地译为“致使喇叭失控、车子失灵”，避免翻译腔。类似的用法再如：He made a mistake, causing us a lot of trouble.7. renowned: a. 享有声誉的，有声望的，有名的 【拓展】renown: n. 名誉，声望e.g. He won renown as a fair judge.8. high-voltage: a. 高电压的 e.g. high-voltage power lines 高压电线9.insulin pump: a medical device that is used for the administration of insulin in the treatment of diabetes mellitus 胰岛素泵10.But what many fail to realize is the awesome potential of a smartphone to watch you1) 画线部分为what 引导的主语从句，再比如：What everyone expects is an environment-friendly society.2) 此处的watch 意为“监视，监控”。11. Research into hacking smart TV sets is now taking off.此处的take off 是指“迅速流行”，即become successful or popular very quickly or suddenly。e.g. The new magazine has really taken off.12. With Internet-connected appliances starting to enter the picture and the arrival of home automation systems that can control key functions of a house remotely1) 这是一个由介词with 引导的伴随状语，with 通常可以翻译成“随着”。再如：The shadows lengthened with the sunset approaching.2) enter the picture 意为“介入，发挥作用”，其近义短语有：play a role。e.g. Things started to change when the Internet entered the picture.13. Thats now a reality with a new hack that uses a weaponized, longer range radio-frequency identification reader to copy employees access badges.1) identification: n. 辨认，确认；身份证明【拓展】identify: v. 确认；发现；说明身份 identity: n. 身份；特征e.g. Passengers were asked to identify their own suitcases before they were put on the plane. Do you have any proof of identity?2) 该句先用thats now a reality 说明“这是现实”，再用with 引出具体的事实。翻译时可以先说具体的事实“新的黑客袭击会使用一种更大范围的武器化的无线电频率身份识别器来复制员工的出入证”，再总结“这已经成为了现实”。14.All a criminal has to do is walk past you, and youve been cloned.该句画线部分是一个省略了关系代词that 的定语从句。再如：All (that) you need to do is try your best.15.confident: a. 自信的【拓展】confidence: n. 信心，自信心 gain / lose confidence: 获得/ 失去信心 take sb. into your confidence: 向某人吐露秘密e.g. After the failure, he loses confidence in his abilities.
