Seed plants are the foundation of human diets across the world. In many societies, vegetarians fare almost exclusively and depend solely on seed plants for their nutritional needs. A few crops (rice, wheat, and potatoes) dominate the agricultural landscape. Many crops were developed during the agricultural revolution when human societies made the transition from nomadic hunter-gatherers to horticulture and agriculture. Cereals, rich in carbohydrates, provide the staple of many human diets. Beans and nuts supply proteins. Fats are derived from crushed seeds or fruits such as olives. Staple crops are not the only foods derived from seed plants. Fruits and vegetables provide nutrients, vitamins, and fiber. Sugar, to sweeten dishes, is produced from sugarcane and sugar beets. Drinks are made from infusions of tea leaves, chamomile flowers, crushed coffee beans, or powdered cocoa beans. Spices come from many different plant parts: saffron and cloves are stamens and buds, black pepper and vanilla are seeds, the bark of a bush in the Laurales family supplies cinnamon, and the herbs that flavor many dishes come from dried leaves and fruit, such as the red chili pepper. Additionally, no discussion of seed plant contribution to the human diet would be complete without the mention of alcohol. Fermentation of plant-derived sugars and starches is used to produce alcoholic beverages in all societies. In some cases, the beverages are derived from the fermentation of sugars from fruit, as with wines, and in other cases, they’re derived from the fermentation of carbohydrates from seeds, as with beers. Seed plants have many other uses, including providing wood as a source of timber for construction and material to build furniture. Most paper is derived from the pulp of coniferous trees. Fibers of seed plants, such as cotton, flax, and hemp, are woven into cloth. Textile dyes, such as indigo, were mostly of plant origins until the advent of synthetic chemical dyes. The medicinal properties of plants have been known to human societies since ancient times. There are references to the use of plants’ curative properties in Egyptian, Babylonian, and Chinese writings from 5,000 years ago. Biodiversity ensures a resource for new food crops and medicines. Plant life balances ecosystems, protects watersheds, mitigates erosion, moderates climates and provides shelter for many animal species. Threats to plant diversity, however, come from many angles. The explosion of human population, especially in tropical countries where birth rates are highest and economic development is in full swing, is leading to human encroachment into forested areas. To feed the larger population, humans need to obtain arable land, so there is a massive clearing of trees. The need for more energy to power larger cities and economic growth therein leads to the construction of dams, which may bring about the consequent flooding of ecosystems and increased emissions of pollutants. The number of plant species becoming extinct is increasing at an alarming rate. Because ecosystems are in a delicate balance, and seed plants maintain close symbiotic relationships with animals, the disappearance of a single plant can lead to the extinction of connected animal species. A real and pressing issue is that many plant species have not yet been cataloged, and so their place in the ecosystem is unknown. These unknown species are threatened by logging, habitat destruction, and loss of pollinators. They may become extinct before we have the chance to begin to understand the possible impact of their disappearance. Efforts to preserve biodiversity take several lines of action, from preserving heirloom seeds to barcoding species. Heirloom seeds come from plants that were traditionally grown in human populations, as opposed to the seeds used for large-scale agricultural production. Barcoding is a technique in which one or more short gene sequences, taken from a well-characterized portion of the genome, are used to identify a species through DNA analysis.

如果我們重新觀察文章中關於「素食者」的部分,以及文中描述「水果與蔬菜」能為人類身體帶來的具體貢獻,你能從這兩處找到共同點,並試著用一句話描述植物如何支撐素食者的健康嗎?

同學,恭喜你精準地鎖定了正確答案!這顯示你對於長篇文章中的細節對應掌握得非常出色。
文本資訊的整合與驗證
這題的核心考點在於對於文章多處細節的歸納。選項 (C) 的正確性可以從第一段與第二段得到印證:文中首段提到素食者(vegetarians)完全依賴種子植物來滿足其營養需求(nutritional needs);緊接著在第二段說明了果實與蔬菜能提供營養素、維生素與纖維(nutrients, vitamins, and fiber)。你能夠將這兩段落的資訊串連,並排除其他具干擾性的錯誤敘述,這正是高效閱讀的表現。
