主题:目前世界上大多数机动车都使用石油作为燃料,而燃烧石油会释放二氧化碳,加剧全球变暖问题。 工程师已经开发了几种替代方案来替代燃烧石油,其中包括氢燃料电池、生物燃料和从空气中提取燃料三种主要方法。 | |
1. 氢燃料电池通过将氢与氧气结合产生电力,不会产生二氧化碳排放,只会产生清洁水; |
1. 氢燃料电池虽然不会产生直接的二氧化碳排放,但生产氢气需要使用化石燃料,导致间接排放二氧化碳; |
2. 生物燃料是由植物材料如玉米或甘蔗制成,虽然燃烧后也会释放二氧化碳,但植物在生长过程中吸收了相同数量的二氧化碳,达到碳平衡; |
2.生物燃料的生产需要大量农田,而当前的农田面积已无法满足同时生产燃料和食物的需求; |
3. 从空气中提取碳来制造合成石油燃料的技术虽然仍处于实验阶段,但科学家们相信这种方法在可预见的未来将成为市场上可行的选择,因为它可以实现对大气中二氧化碳的完全循环利用。 |
3. 从空气中提取碳虽然是一个有前景的技术,但目前的效率低,无法满足全球对燃料的需求。 |

Doctor Diaz:
People travel for many reasons. Traveling allows people to practice a different language, explore and admire new landscapes, and encounter other cultures. In the past, physical travel was the only practical way to experience the pleasures and benefits of traveling. Today, television and the Internet allow people to experience many aspects of distant places without leaving their homes. Do you believe that exploring other places through technology offers many of the same benefits as in-person travel? Why or why not?
Claire:
Absolutely, virtual travel offers many benefits of physical travel. Through the internet and TV, we can immerse ourselves in the scenery, different cultures, and even pick up languages - all from home. It's eco-friendly, cost-effective, and allows us to better prepare for an actual trip.
Andrew:
I don't believe exploring places through technology offers the same benefits as in-person travel. While virtual tours and online content give us a glimpse into different cultures, they fail to fully capture the sights, smells, sounds and feel of being there physically. It's only a shallow substitute for the real thing.
范文:
From my perspective, though traveling online would literally help save large quantities of time on the road and drastically cut down the expense, taking the trip in person could undoubtedly bring more benefits. To begin with, visiting the area would help tourists have close access to local culture and communicate directly with native individuals, thus having a much clearer and more accurate understanding of the traveling destination. For example, only by observing the magnificent landscape in Yellowstone Park on our own can we have a real impression of all the species living there, while the photos or reviews from others can never be so surprising. Besides, one can hardly taste the local delicacy without engaging in the journey in person. Take those who have a strong enthusiasm for pizza as an example. The videos or photos of some characteristic pizzas may contain the general features of ingredients or some descriptions of the peppers from others, but viewers can never truly taste it without taking a bite themselves. Thus, to have a great trip, people ought to take the trip in person.
