TOEFL Reading Text:

The mineral particles found in soil range in size from microscopic clay particles to large boulders. The most abundant particles — sand, silt, and clay — are the focus of examination in studies of soil texture. Texture is the term used to describe the composite sizes of particles in a soil sample, typically several representative handfuls.

To measure soil texture, the sand, silt, and clay particles are sorted out by size and weight. The weights of each size are then expressed as a percentage of the sample weight. In the field, soil texture can be estimated by extracting a handful of soil and squeezing the damp soil into three basic shapes; (1) cast, a lump formed by squeezing a sample in a clenched fist; (2) thread, a pencil shape formed by rolling soil between the palms; and (3) ribbon, a flat shape formed by squeezing a small sample between the thumb and index finger. The behavioral characteristics of the soil when molded into each of these shapes, if they can be formed at all, provide the basis for a general textural classification. The behavior of the soil in the hand test is determined by the amount of clay in the sample. Clay particles are highly cohesive, and when dampened, behave as a plastic. Therefore the higher the clay content in a sample, the more refined and durable the shapes into which it can be molded.

Another method of determining soil texture involves the

TOEFL Reading Practice: Soil Texture

As a TOEFL test taker, mastering the reading section is crucial for achieving a high score. One topic that frequently appears in the reading passages is soil texture. Understanding this subject not only helps you answer related questions but also enhances your overall knowledge of environmental science. ??

What is Soil Texture?

Soil texture refers to the composition of soil particles, which includes sand, silt, and clay. The proportions of these particles determine the soil's characteristics, such as water retention, nutrient availability, and aeration. Knowing the differences between these textures can help you understand how they affect plant growth and agricultural practices.

Key Terms:

• Sand: Coarse particles that allow for good drainage but have lower nutrient retention.
• Silt: Medium-sized particles that hold moisture well and provide nutrients.
• Clay: Fine particles that retain water and nutrients but may lead to poor drainage.

Sample Passage:

Soil texture plays a significant role in determining the health of an ecosystem. For instance, sandy soils drain quickly, making them less suitable for crops that require consistent moisture. In contrast, clay soils can hold water but may become compacted, limiting root growth. Understanding these properties allows farmers to select appropriate crops for their specific soil types.

Practice Questions:

1. What is the primary factor that influences soil texture?
2. How does sandy soil affect crop growth compared to clay soil?
3. Why is it important for farmers to understand soil texture?

Answers:

1. The primary factor influencing soil texture is the proportion of sand, silt, and clay particles.
2. Sandy soil drains quickly, which may not support crops needing consistent moisture, while clay soil retains water but can become compacted.
3. Understanding soil texture helps farmers choose suitable crops based on the soil's water retention and nutrient availability.

New Practice Question:

Read the following text and answer the question below:

Different soil textures can influence the effectiveness of fertilizers. For example, clay soils may require different types of fertilizers than sandy soils due to their varying nutrient retention capabilities. Farmers must adjust their fertilization strategies according to soil texture to optimize crop yield.

Question: How does soil texture affect fertilization strategies?

Predicted Answer: Soil texture affects fertilization strategies because clay soils hold nutrients differently than sandy soils, requiring farmers to adjust their fertilizer types and application methods accordingly.

Tips for TOEFL Reading Section:

• Practice skimming the passage to get the main idea before diving into the details.
• Highlight or take notes on key terms as you read to improve retention.
• Familiarize yourself with common academic vocabulary related to environmental science.
• Time yourself while practicing to improve your speed and comprehension under pressure.

By focusing on topics like soil texture and understanding how to approach related questions, you can enhance your performance in the TOEFL reading section. Remember, consistent practice is key! ?? Good luck!

托福真題閱讀解析經驗分享

在備考托福的過程中，閱讀部分往往是許多考生感到挑戰(zhàn)的一環(huán),。通過分析托福真題閱讀,，我們可以更好地理解考試的出題方向以及提高自己的解題技巧。以下是我的一些經驗分享,，希望能幫助到正在準備托福的你,！??

一、理解題型

托福閱讀主要有以下幾種題型：

例如，假設我們閱讀了一篇關于“climate change”的文章,，可能會有以下題目：

題目: What is the main idea of the passage?

參考答案: The passage discusses the impact of climate change on global ecosystems.

三,、積累詞匯

詞匯量的豐富程度直接影響閱讀理解能力,。建議大家可以通過以下方式來積累詞匯：

• Flashcards - 制作單詞卡片，隨時隨地復習,。
• Contextual Learning - 在上下文中學習新詞,，理解其用法。
• Regular Reading - 多讀英文文章,，增加對不同領域詞匯的接觸,。

比如，在閱讀時遇到“biodiversity”這個詞,，應該理解它的意思是“生物多樣性”,，并且知道它在環(huán)境科學中的重要性。??

四,、模擬考試

參加模擬考試是檢驗自己水平的有效方法,。建議按照真實考試的時間限制進行練習，并盡量在安靜的環(huán)境中完成,。這樣可以幫助你適應考試的節(jié)奏和壓力,。
