In fact, in the early days, a person might live their whole life in one village. The first important invention in land travel was the wheel. And then came the wagons. Humans began to have the power to move and carry things across long distances. The next was the train. After the train came the invention of cars, buses, trucks, and other means of transportation. Humans and goods were able to travel farther than ever before. Boats and ships provided another important way of travelling. The invention of the compass helped people explore more places. And canal systems made fast waterway transportation possible. 23021 Modern means of transportation, such as high-speed trains and airplanes, help people travel faster and farther. Eco-friendly electric cars are common and self- driving cars are in development. People can even travel to space in spaceships. Who knows what the future holds?

In fact, in the early days, a person might live their whole life in one village. e.g. In fact, it is very hot. 事实上，天很热。 He is not happy, and in fact, he is very sad. 他不高兴，确切地说，他很伤心。 I don’t like coffee. As a matter of fact, I’ve never tried it. 我不喜欢咖啡。事实上，我从来没喝过它。 She speaks French, and in addition, she knows Spanish. 她说法语，此外她还懂西班牙语。 23021 e.g. She has the power to solve complex problems. 她有解决复杂问题的能力。 Wind power is becoming more and more popular. 风能正变得越来越受欢迎。 The new plane is powered by electric engines. 这架新飞机由电动引擎驱动。 2. Humans began to have the power to move and carry things across long distances. power 的一词多义：(1) 作不可数名词，意为“能力；权力”，指人、组织或国家的支配力、影响力。(2) 作不可数名词，意为“能；电力”，指物理能量(如电力、动力) 或机器运转的能量。常用搭配：electric power电力；power supply 电力供应；solar power 太阳能。(3) 作动词，意为“驱动；推动”，指机器、能源等为某物提供动力使其运转。 常见搭配：be powered by 由……驱动 相关词汇：powerful adj. 强大的；力量大的 23021 3. Modern means of transportation, such as high-speed trains and airplanes, help people travel faster and farther. 这是一个简单句。主语是Modern means of transportation，such as high-speed trains and airplanes 是一个插入语，用来列举具体的现代交通方式。谓语是help，宾语是people，travel faster and farther 是宾补，表示“出行得更快、更远”。 23021 speed 的一词多义：(1) 作名词，意为“速度；速率”，指物体运动、行进或发生的快慢程度。常见搭配：at high/low speed 以高/ 低速 speed limit 限速 at the speed of 以……的速度 (2) 作动词，意为“加速；促进”，表示移动速度加快。 speed up(使) 加速。 相关词汇：(1) speedy adj. 迅速的；快速的 (2) speedily adv. 迅速地 e.g. The speed of light is about 300,000 kilometers per second. 光速约为每秒30 万千米。 The train reached a top speed of 350 km/h. 这列火车达到了每小时350 公里的最高速度。 We need to speed up if we want to catch the bus. 如果想赶上公交车，我们得加快速度。 23021 common 作形容词，意为“普通的；常见的；共同的；共有的”。 还可作可数名词，表示“公共用地；公地”。 常见用法：(1) in common 共有 (2) in common with... 和……一样 (3) have... in common with... 和……在……方面有共同之处 4. Eco-friendly electric cars are common and self-driving cars are in development. e.g. We have common topics to talk about. 我们有共同的话题可谈。 In common with many people, he prefers classical music to pop. 和许多人一样，他喜欢古典音乐胜过流行音乐。 He has nothing in common with his father. 他和他父亲无共同之处。 23021 分析结构：这是一个含宾语从句的特殊疑问句。Who knows 是主句，疑问代词Who 作主语，knows 是谓语动词。宾语从句what the future holds 由what 引导，作knows 的宾语。what 在从句中作宾语，指代“发生的事”。the future 是从句中的主语，holds 是从句中的谓语。 由特殊疑问词引导的宾语从句也需用陈述句语序(即“主语+ 谓语”顺序) ，即使主句是疑问句，从句也不能倒装。 主句的谓语动词是现在时或将来时，宾语从句的谓语动词按句子意思自由选择时态；主句的谓语动词是过去时，宾语从句的谓语动词一般使用对应的过去时态；若宾语从句表示的是客观真理或永久性情况，通常用现在时。 5. Who knows what the future holds? 23021 e.g. Nobody knows what will happen in the future. 没有人知道未来会发生什么。 The police officer stopped us and asked us where we were going. 警官拦住了我们并问我们将要去哪儿。 23021 3 Read and complete the passage.
