Pay attention to the incomplete plosions and the intonations. 1. A: How much do you know abou(t) water-powered energy? B: I(t) comes from the falling water or running water. 2. A: Can you tell me wha(t) renewable energies are ma(d)e from? B: It is ma(d)e from natural resources, like win(d), water an(d) sunlight(t). 17 意群（Sense group） 意群：在英语句子里，按照意思和语法结构划分出来的小片段，一个意群表达 一层相对完整的含义。 •主谓之间、动宾之间如果较长，可以切分意群 例：We can see / many kinds of high‑tech products / in our daily life. •介词短语单独划为一个意群 例：People order food / on their mobile phones / in this special restaurant. •定语从句单独划分为一个意群 例：It is a machine / that helps farmers grow crops more easily. •连词分隔的分句，前后各为独立意群 例：Technology brings convenience, / but it also has some problems. Pause（停顿） 1. Short pause（短停顿）：意群和意群之间 同一个句子内部，不同意群中间，做很短的停顿，轻微换气，不代表语义结束。停顿时间短，只做短暂换气，不要过长。 例：The robot restaurant uses artificial intelligence / to serve customers / in many ways. 2. Long pause（长停顿）：陈述句、疑问句等完整句子的末尾 一句话语义完全结束，使用长停顿，停顿时间比短停顿久，完成换气。 例：Artificial intelligence is changing our daily life. // 注意：逗号处一般用短停顿/；句号、问号、感叹号结尾，使用长停顿 “//”。 例：Modern technology / has brought us convenience, / but it also brings some challenges. // Listen and repeat. Pay attention to the sense groups and pauses. When New Year’s Day comes, / buying presents / is an important thing / for a lot of people. / However, / many people do their shopping / at home / instead of leaving their houses / nowadays. / With the help of the internet, / people don’t have to line up / in busy shops. / They can buy things online / at lower prices. / And they can get almost anything / they like / with just a few clicks of the mouse. 20 Vocabulary self-driving ▶adj. 自动驾驶的；自行驱动的 self（自己）+ driving（驾驶），合成形容词，中间带连字符。 •self‑driving car 自动驾驶汽车 •self‑driving system 自动驾驶系统 •self‑driving technology 自动驾驶技术 例：Self‑driving cars can see everything on the road. （自动驾驶汽车能够识别路面上所有物体。） This self‑driving system has passed many strict road tests. （这套自动驾驶系统已经通过了多项严格的道路测试。） decision ▶n. 决定；抉择 •make decisions/a decision 做决定 例：We need to make a decision about the high-tech restaurant.（我们需要就这家高科 技餐厅做出决定。） •make the decision 做出这个决定（特指） 例：The self-driving car can make the right driving decisions.（自动驾驶汽车能够做出 正确的驾驶判断。） •make a decision to do sth 决定去做某事 例：He made a decision to learn more about new technology.（他决定去学习更多新技 术相关知识。） exactly ▶adv. 精确地；准确地；恰好 用来修饰动词、形容词或副词，强调完全符合事实、时间、数量。 例：Please tell me exactly how the self-driving car works.（请准确告诉我自动驾驶汽车如 何工作。） ▶adv. 正是如此；一点不错（口语交际） 单独使用，用来对别人的观点表示完全赞同，相当于 You are right. 例：—Can the car make driving decisions by itself?（这辆车可以自己做出驾驶判断吗？） —Exactly.（没错。） Exercise 单项选择 1.
