想要提升自己的托福聽力反應速度,，除了不斷做好托福聽力練習和詞匯累積之外,，一些相關的背景知識也會為大家的備考帶來很大的幫助,。那么,，在以下的內容中就為大家整理了托福聽力必備背景知識。

TOEFL Listening Background Knowledge - Botany

Botany, a branch of biology, focuses on the study of plants, including their structure, growth, reproduction, metabolism, development, chemical properties, diseases, and evolution. Research can be approached from various angles, examining plant organelles, cells, tissues, organs, individuals, and populations to uncover molecular, genetic, and biochemical information. Early human studies of plants were primarily aimed at identifying edible, medicinal, or toxic species, establishing botany as one of the oldest scientific disciplines. Today, botanists have identified over 550,000 plant species, aiming to develop, utilize, modify, and protect plant resources for human benefits such as food, fiber, medicine, and building materials.

Basic Structure of Plants

Understanding some basic vocabulary related to plants is essential for comprehending TOEFL listening passages. For instance, a tree consists of parts like the trunk, bark, roots, branches, twigs, shoots, leaves, and petioles. Flowers encompass components such as buds, petals, nectar, pollen, pistils, and stamens. Fruits include the peel, flesh, and seeds, with some seeds encased in hard shells for protection.

Photosynthesis

Photosynthesis is a vital process for plants, humans, and the entire planet. In simple terms, it refers to the ability of green plants to convert absorbed carbon dioxide and water into organic compounds while releasing oxygen. This process relies heavily on chlorophyll and various enzymes found in leaves. Through photosynthesis, plants consume carbon dioxide, a greenhouse gas produced by human activities, and release oxygen, essential for human survival. The organic compounds produced serve as energy sources for animals, making plants the producers in the food chain.

Uses of Plants

In addition to providing food, plants have numerous other essential uses. Many medicinal compounds are derived from plants; for example, the active ingredient in aspirin comes from willow bark, while morphine, a narcotic analgesic, is extracted from the opium poppy. Common stimulants like coffee, chocolate, tobacco, and tea are also plant-derived. Fermentation of plants like barley, rice, and grapes produces various alcoholic beverages.

Plants provide fibers such as cotton and hemp, while silk production relies on the mulberry tree. Additionally, plants can be used to create ropes, rubber, and other materials that enhance human life.

As accessible organisms, plants are ideal for conducting experiments on fundamental life processes, such as cell division and protein synthesis, without the ethical concerns associated with animal or human testing. For instance, Gregor Mendel discovered the basic principles of genetics through his studies on pea plants.

Exam Questions Reflection

Various TOEFL preparation books feature questions related to botany. For instance, an official practice test includes a passage about the nightcap oak, detailing its unique growth and reproductive characteristics. Notably, a section in Delta discusses two plant hormones: ethylene and auxin. Although the topic may seem niche and the key terms unfamiliar, understanding the described content and examples helps grasp the main ideas presented, allowing students to relate practical experiences to the material.

Classic exam questions often include a passage about the Corpse Flower (Rafflesia). The professor introduces plant classification, mentioning species and genera, and highlights the challenges of categorizing unique plants. The Corpse Flower emits a foul odor to attract flies for pollination. The professor describes its large flower, which can reach the size of an arm's length, and explains its harsh growing conditions that prevent other plants from thriving. Despite having food sources, this plant resorts to trapping insects for nutrients due to poor soil quality. The discussion emphasizes the rarity of witnessing its blooming process due to specific conditions required for pollination and flowering.

Overall, the intricate relationship between plants and their environment, along with their diverse uses, underscores the importance of botany in both academic and practical contexts, making it a vital area of knowledge for TOEFL test-takers.
