In recent years, the popularity of vegetarianism has been steadily increasing. A vegetarian diet is one that excludes meat, fish, and poultry, focusing instead on plant-based foods such as fruits, vegetables, nuts, and grains. This trend is driven by a variety of factors, including health concerns, environmental considerations, and ethical reasons.
Health-wise, many studies have shown that a vegetarian diet can reduce the risk of chronic diseases like heart disease and diabetes. The lack of saturated fat and cholesterol in plant-based foods makes them a healthier choice for many people. Additionally, vegetarians tend to consume more fiber, vitamins, and minerals, which are essential for good health.
On the environmental front, vegetarianism has significant benefits. The meat industry is a major contributor to greenhouse gas emissions, and reducing meat consumption can help mitigate the impact of climate change. Furthermore, meat production requires vast amounts of water and land resources, which could be better utilized for other purposes.
Ethically, many people choose to become vegetarians due to concerns about animal welfare. Factory farming practices often involve cruel and inhumane treatment of animals, which is a significant issue for many ethical vegetarians. By avoiding meat, they aim to reduce the demand for such practices.
Despite these benefits, however, vegetarianism is not without its challenges. One major challenge is ensuring adequate protein intake, as plant-based proteins are not as readily absorbed by the body as animal proteins. Additionally, some vegetarians may find it difficult to plan balanced meals, especially if they are new to the diet.

【文章概要】
近年來，素食主義日益流行，其核心理念在于排除動物性食品，專注于植物性食材如蔬果、堅果和谷物。其背后推動力量涉及健康、環(huán)境和道德考量。研究顯示，素食有助于降低心臟病和糖尿病風(fēng)險，同時減少溫室氣體排放和水土資源消耗。然而，素食者需面對蛋白質(zhì)攝入不足和膳食均衡的挑戰(zhàn)，尤其是新手素食者。盡管面臨這些困難，素食主義因其多重優(yōu)勢而備受推崇。
【答案解析】
1.[D]文章中提到素食主義流行的原因包括健康擔(dān)憂（A選項）、環(huán)境考慮（B選項）和道德原因（C選項）。但文章并沒有提及“文化傳統(tǒng)”（D選項）作為素食主義流行的原因。因此，D選項是不被提及的素食主義流行的原因。
2.[C]文章明確指出“許多研究表明素食可以降低患心臟病和糖尿病等慢性疾病的風(fēng)險。”，這與C選項“它降低了患慢性疾病的風(fēng)險”相符。而A選項“它增加了患心臟病的風(fēng)險”與文章內(nèi)容相反；B選項“它含有更多的飽和脂肪和膽固醇”與文章內(nèi)容不符，因為文章提到植物性食物缺乏這些成分；D選項“它提供了較少的纖維、維生素和礦物質(zhì)”也與文章內(nèi)容不符。
3.[C]文章提到“減少肉類消費(fèi)可以幫助減輕氣候變化的影響”，這與C選項“它有助于減輕氣候變化的影響”相符。A選項“它需要更少的水和土地資源”雖然部分正確，但不是文章強(qiáng)調(diào)的主要環(huán)境好處；B選項“它是溫室氣體排放的主要貢獻(xiàn)者”與文章內(nèi)容相反，因為文章說的是肉類行業(yè)是溫室氣體排放的主要貢獻(xiàn)者；D選項“它導(dǎo)致對動物的殘忍和不人道的對待”與素食主義對環(huán)境的好處無關(guān)。
4.[A]文章提到“一個主要的挑戰(zhàn)是確保足夠的蛋白質(zhì)攝入，因為植物性蛋白質(zhì)不如動物性蛋白質(zhì)容易被身體吸收。”這與A選項“確保足夠的蛋白質(zhì)攝入”相符。B選項“植物性蛋白質(zhì)的容易吸收”與文章內(nèi)容相反；C選項“規(guī)劃不均衡的膳食”與文章內(nèi)容不符，文章說的是可能難以規(guī)劃均衡的膳食；D選項“植物性食物缺乏多樣性”在文章中并未提及。
