答案解析: 录音中指出vegetarian diet（素餐）是the most energy-efficient（最节能的），而“…fish almost was on par with red meat as the least efficient…”（鱼肉和红肉一样是最不节省能源的），因为进行长途航行去捉掠食性鱼需要大量化石燃料。on par with与…不分上下，与…同等水平。
【录音原文】To find out which types of foods require the most fossil fuels and, as a result, release the most CO₂, they considered five different diets. Each equaled 3,774 calories a day, and ranged from the average American diet to red meat, fish, poultry, and vegetarian diets. It came as no surprise to the researchers that the vegetarian diet ranked number one as the most energy- efficient, followed by poultry and the average American diet. It did come as a surprise, however, that fish almost was on par with red meat as the least efficient-a large amount of fossil fuel is necessary for long-distance voyages to catch large predatory fishes such as tuna and swordfish. Moreover, salmon farming is not energy efficient.
