TOEFL Reading Classic Test: Desert Formation

This passage discusses the Sahara Desert, highlighting that it was not always a desert and once had underground river traces. A key point mentioned is the reason for its formation, particularly the significant temperature fluctuations that lead to the fracturing of rocks. Additionally, the passage elaborates on the cyclical processes that the Sahara has undergone, which is also a potential exam point. Lastly, it explores the relationship between studying Earth's deserts and investigating other planets, which could serve as another question.

TOEFL Reading Classic Test: Beach Formation

This section covers the conditions necessary for beach formation, detailing the composition and size of beaches. It notes that some beaches are made up of coral, others of stones, and some of sand. For instance, the California coast experiences seasonal changes in beach composition. Furthermore, the passage emphasizes that ideal beach formation requires smooth geographical conditions; certain areas along the U.S. East Coast benefit from protective barriers that enhance their beaches, in contrast to those found in Europe. The final paragraphs discuss the role of water in shaping beaches.

托福閱讀技巧分享

對(duì)于許多托福考生來(lái)說(shuō),，閱讀部分可能是最具挑戰(zhàn)性的部分之一,。為了幫助你在托福閱讀中取得更好的成績(jī)，以下是一些實(shí)用的技巧和策略,。

1. 理解題型

托福閱讀包含多種題型,，比如：

• Factual Information: 這些問(wèn)題通常要求你找到文中的具體信息。
• Negative Factual Information: 這類問(wèn)題要求你識(shí)別不正確的信息,。
• Inference: 需要你根據(jù)文本內(nèi)容進(jìn)行推理,。
• Vocabulary: 這類問(wèn)題測(cè)試你對(duì)特定單詞的理解。
• Sentence Insertion: 需要你判斷某句子在段落中的最佳位置,。

了解這些題型可以幫助你在閱讀時(shí)更有針對(duì)性地尋找信息,。??

2. 精讀與略讀結(jié)合

在托福閱讀中，精讀和略讀是兩種重要的閱讀方式,。精讀適用于理解復(fù)雜的段落，而略讀則幫助你快速獲取文章的大意,。

例如,，在閱讀一篇關(guān)于“Climate Change”的文章時(shí)，你可以先略讀標(biāo)題和每段的首句,，以獲取文章的整體框架,，然后再針對(duì)重要段落進(jìn)行精讀。

3. 做好筆記

在閱讀過(guò)程中,，記下重要的細(xì)節(jié)和主題是非常有幫助的,。你可以使用簡(jiǎn)短的符號(hào)或縮寫來(lái)記錄關(guān)鍵信息。??

例如,，在閱讀時(shí)如果遇到一個(gè)新的單詞,，可以在旁邊寫下它的意思或同義詞，這樣可以幫助你在回答相關(guān)問(wèn)題時(shí)更快地回憶起信息,。

4. 時(shí)間管理

托福閱讀部分有時(shí)間限制,，因此合理安排時(shí)間至關(guān)重要。建議你在每篇文章上花費(fèi)20分鐘,，這樣可以確保你有足夠的時(shí)間完成所有問(wèn)題,。?

可以設(shè)置一個(gè)計(jì)時(shí)器,，幫助自己在規(guī)定時(shí)間內(nèi)完成閱讀和答題，避免在某一題上過(guò)于糾結(jié),。

5. 練習(xí)真題

通過(guò)做托福真題,，你可以熟悉考試的格式和題型。建議你至少完成3-5套真題,，并認(rèn)真分析錯(cuò)題,。在分析時(shí)，考慮以下幾個(gè)方面：

• 為什么選擇了錯(cuò)誤的答案,？
• 正確答案的依據(jù)是什么,？
• 是否有其他可能的答案？

這樣的練習(xí)可以幫助你提高解題能力和速度,。

6. 擴(kuò)充詞匯量

詞匯是閱讀理解的基礎(chǔ),。建議每天學(xué)習(xí)10-15個(gè)新單詞，并嘗試將它們應(yīng)用于句子中,。??

你可以使用閃卡或者手機(jī)應(yīng)用程序來(lái)幫助記憶,，同時(shí)也要注意同義詞和反義詞的學(xué)習(xí)，這對(duì)理解文章中的詞匯非常重要,。

7. 注意文章結(jié)構(gòu)

托福閱讀文章通常具有明確的結(jié)構(gòu),，如引言、主體和結(jié)論,。理解這種結(jié)構(gòu)可以幫助你更快地找到信息,。例如：

• 引言部分通常提出主題或問(wèn)題。
• 主體部分提供支持信息和例證,。
• 結(jié)論部分總結(jié)主要觀點(diǎn),。

在閱讀時(shí)，留意這些結(jié)構(gòu)變化可以幫助你更好地理解文章內(nèi)容,。

8. 保持積極心態(tài)

最后,，保持積極的心態(tài)也是成功的關(guān)鍵。即使遇到困難的文章,，也不要?dú)怵H,。每次練習(xí)都是一個(gè)學(xué)習(xí)的機(jī)會(huì)。??

通過(guò)不斷的努力和實(shí)踐,，你一定能夠提高自己的閱讀能力,，為托福考試做好準(zhǔn)備,！

When preparing for the TOEFL exam, understanding various environmental topics can be quite beneficial. One such topic is the formation of deserts. ?? In this article, we will analyze the reasons behind desert formation, which not only improves your knowledge but also enhances your ability to articulate your thoughts during the exam.

1. Climate Factors

The primary reason for desert formation is climatic conditions. Deserts typically arise in regions where there is limited rainfall. ??? The rain shadow effect is a significant contributor to this phenomenon. When moist air travels over mountains, it cools and loses moisture as precipitation. The leeward side of the mountain range remains dry, creating arid conditions that can lead to desert formation.

2. Latitude Influence

Another important factor is latitude. Deserts are often found around 30 degrees north and south of the equator. ?? This is due to the Hadley cell circulation, where warm air rises at the equator, cools, and descends at these latitudes, leading to high-pressure systems that inhibit cloud formation and precipitation.

3. Soil and Vegetation

The type of soil and vegetation in an area also plays a role in desert formation. Areas with poor soil quality may not support vegetation, which can lead to increased erosion and further desertification. ?? Without plants to retain moisture, the ground becomes more susceptible to drying out, reinforcing the desert conditions.

4. Human Activities

Human activities are increasingly contributing to desert formation. Deforestation, overgrazing, and unsustainable agricultural practices can accelerate the process of desertification. ?? For instance, when forests are cleared for agriculture, the soil loses its nutrients and structure, making it less capable of retaining water. This leads to a higher likelihood of transforming fertile land into desert.

5. Natural Events

Natural events such as droughts and wildfires can also contribute to desert formation. ?? Prolonged periods of drought can deplete water sources, while wildfires can destroy vegetation that helps maintain the ecosystem's balance. Once vegetation is lost, the land can quickly become desert-like.

6. Examples of Deserts

To better illustrate these factors, let’s look at some examples of well-known deserts. The Sahara Desert in Africa is primarily influenced by its location in the subtropical high-pressure zone, while the Mojave Desert in North America is affected by both the rain shadow effect and human activities. ?? Understanding these examples can help you draw connections during your TOEFL exam.

7. Vocabulary Building

As you study this topic, it's essential to build your vocabulary. Here are some key terms related to desert formation:

• Desertification
• Arid
• Climate Change
• Precipitation
• Ecosystem Balance

8. Practice Questions

Consider these practice questions to enhance your understanding:

• What are the main climatic factors that lead to desert formation?
• How do human activities contribute to desertification?
• Can you provide an example of a desert and explain its formation?

9. Listening and Reading Comprehension

For listening and reading comprehension, try to find materials discussing environmental science or geography. Look for texts that detail the processes of desert formation and the impact of climate on ecosystems. ?? This will not only prepare you for the TOEFL but also deepen your understanding of global environmental issues.

In conclusion, analyzing the reasons behind desert formation provides valuable insights into environmental science. As a TOEFL test-taker, being able to discuss these topics thoughtfully can set you apart. ?? By focusing on the climatic, geographical, and human factors involved, you can enhance both your knowledge and your language skills, preparing you for success on the exam.
