1托福閱讀主旨題如何判斷主旨與細節(jié)
托福閱讀主旨題如何判斷主旨與細節(jié)是考生們在備考過程中常常遇到的問題,。掌握這一技巧不僅能幫助考生在考試中提高分數(shù),，還能加深對文章內(nèi)容的理解。本文將通過實例分析,，幫助大家更好地識別主旨信息與細節(jié)信息,。
Understanding Main Ideas and Details in TOEFL Reading
One of the last questions in the TOEFL reading section involves selecting three correct answer choices from six options to summarize the passage. The key feature of correct answers is that they express "the most important ideas in the passage", representing the core information. In contrast, incorrect options often reflect specific details from the text. Let's analyze two examples to illustrate how to distinguish between main ideas and details.
Example Passage Title: MINERALS AND PLANTS
The following are the main points from each paragraph:
Paragraph 1: Research indicates that certain minerals are essential for plants' normal growth and development.
Paragraph 2: Mineral deficiencies can be identified by symptoms like chlorosis, necrosis, and stunted growth.
Paragraph 3: Much research on nutrient deficiencies is conducted using hydroponically grown plants.
Paragraph 4: While mineral deficiencies hinder plant growth, excessive minerals can also be toxic.
Paragraph 5: Some plants, known as hyper accumulators, can concentrate minerals significantly more than normal levels.
Paragraph 6: Recently, researchers have explored using these plants for phytoremediation to clean contaminated soils.
Question:
Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage.
Plants need to absorb certain minerals from the soil in adequate quantities for normal growth and development.
1. Some plants are able to accumulate extremely high levels of certain minerals and thus can be used to clean up soils contaminated with toxic levels of these minerals.
2. Though beneficial with lower levels, high levels of salts, other minerals, and heavy metals can be harmful to plants.
3. When plants do not absorb sufficient amounts of essential minerals, characteristic abnormalities result.
4. Because high concentrations of sodium chloride and other salts limit growth in most plants, much research has been done in an effort to develop salt-tolerant agricultural crops.
5. Some plants can tolerate comparatively low levels of certain minerals, but such plants are of little use for recycling nutrients back into depleted soils.
6. Mineral deficiencies in many plants can be cured by misting their roots with a nutrient solution or by transferring the plants to a soilless nutrient solution.
Correct Answers: 1, 2, 3.
Notice that option 1 corresponds with paragraphs 5 and 6; option 2 relates to paragraph 4; and option 3 aligns with paragraph 2. Therefore, identifying the main idea of each paragraph serves as a reliable method to determine the correct choices.
Moreover, it is crucial to practice eliminating incorrect options, which often represent detailed information. Let's examine another example.
Example Passage Title: APPLIED ARTS AND FINE ARTS

Answer: C. The melting ice caps threaten polar bears' survival.
通過這樣的練習(xí)，你可以更好地理解如何從選項中提煉出正確答案,。??
多做模擬練習(xí)
為了提高你的應(yīng)試能力,，建議進行大量的模擬練習(xí)。使用托福官方指南或其他備考書籍中的閱讀材料,，定期進行測試,。記得在每次練習(xí)后，分析錯誤的原因,，并查找相關(guān)的知識點以加強理解,。??
