托福閱讀高難度文章長難句實例解析：石油是有機物分解產(chǎn)物,。在托福考試中,，長難句的理解往往是考生面臨的一大挑戰(zhàn),。通過對具體句子的分析，考生可以更好地掌握復(fù)雜句子的結(jié)構(gòu),，從而提高閱讀理解能力,。

Example of a Complex Sentence:

Two additional kinds of evidence support the hypothesis that petroleum is a product of the decomposition of organic matter.

Structure Analysis:

This sentence is a compound sentence. The main structure includes a subject + verb + object, with an appositive clause following the object; after the colon, there is a noun phrase that serves as an appositive for the subject.

Sentence Breakdown:

The subject "two additional kinds of evidence" supports the hypothesis, which is further explained by the clause "that petroleum is a product of the decomposition of organic matter." Here, "petroleum" acts as the subject, and "is a product" serves as the linking verb structure; the prepositional phrase "of the decomposition of organic matter" modifies the predicate. This part conveys: There are two more pieces of evidence supporting the hypothesis that petroleum results from the breakdown of organic materials.

Evidence Breakdown:

The first piece of evidence states: "Oil possesses optical properties known only in hydrocarbons derived from organic matter."

In this section, "oil" is the subject, "possesses" is the verb, and "optical properties" is the object. The past participle phrase "known only in hydrocarbons" serves as a post-modifier for "properties," while "derived from organic matter" modifies "hydrocarbons." The meaning here is: Oil has optical characteristics that are exclusive to hydrocarbons originating from organic matter.

The second piece of evidence states: "Oil contains nitrogen and certain compounds believed to originate only in living matter."

For this part, "oil" is again the subject, "contains" is the verb, and "nitrogen and certain compounds" are the compound objects. The post-modifier "believed to originate only in living matter" describes "compounds." This conveys: Oil includes nitrogen and some compounds thought to come solely from living organisms.

Reference Translation:

還有另外兩種證據(jù)能支持石油是有機物分解的產(chǎn)物這一假設(shè)：一是石油具有光學(xué)特性，這些特性只有源自有機物的碳氫化合物中才有;二是石油含有氮和某些化合物,，人們認為這些化合物只能來源于有生命的物質(zhì),。

通過對托福閱讀中長難句的深入分析，考生可以有效提升應(yīng)對復(fù)雜句子的能力,，更加從容地面對考試挑戰(zhàn),。希望以上的示例與解析能幫助大家在備考中取得更好的成績！

Understanding Long Sentences in TOEFL Reading

For many TOEFL test-takers, long and complex sentences in the reading section can be daunting. However, with the right strategies, you can tackle these sentences effectively. Here are some tips to help you break down and understand long sentences better. ??

1. Identify the Main Idea

Before diving into the details, try to identify the main idea of the sentence. Look for the subject and the verb, as they often provide the core message. For example, in the sentence:

“The research conducted by scientists in the Arctic, which has been ongoing for over a decade, reveals significant changes in climate patterns.”

Here, the main idea is that the research reveals changes in climate patterns. The rest of the sentence provides additional information about the research.

2. Break It Down

Long sentences can often be broken down into smaller parts. Look for clauses and phrases that can stand alone. For instance:

“Although the experiment was challenging, the results, which were unprecedented, demonstrated a clear correlation between the variables.”

This sentence can be divided into two parts: the challenge of the experiment and the significance of the results. Breaking it down makes it easier to digest. ??

3. Pay Attention to Connectors

Connectors like “although,” “however,” and “because” signal relationships between ideas. Understanding these connections can clarify the meaning. For example:

“The theory, although controversial, has gained traction among some researchers because of its compelling evidence.”

Here, “although” indicates a contrast, while “because” explains the reason for the theory's acceptance. Recognizing these connectors can help you follow the author’s logic. ??

4. Practice with Sample Sentences

To improve your skills, practice with sample sentences. Here’s one to analyze:

“Despite the overwhelming evidence supporting the new treatment, many practitioners remain skeptical due to longstanding beliefs.”

Identify the main idea (practitioners are skeptical) and break it down (evidence vs. beliefs). This method will enhance your comprehension during the actual test.

5. Vocabulary Matters

A strong vocabulary is essential. When encountering unfamiliar words, try to deduce their meanings from context. For instance:

“The phenomenon, which has been observed across various ecosystems, poses a significant threat to biodiversity.”

Even if you don’t know “phenomenon,” you can infer that it relates to something noteworthy affecting biodiversity.

6. Time Management

During the TOEFL test, time is limited. Practice reading long sentences quickly but accurately. Set a timer while practicing to simulate test conditions. This will help you become more efficient in identifying key points without getting stuck on difficult parts. ?

7. Utilize Resources

Consider using online resources or TOEFL preparation books that focus on reading comprehension. Engaging with different texts will familiarize you with various writing styles and sentence structures.

8. Stay Calm and Focused

Finally, remember to stay calm during the test. Anxiety can hinder your ability to comprehend long sentences. Take deep breaths and approach each sentence methodically. ???♂?

By applying these strategies, you can enhance your ability to understand long sentences in the TOEFL reading section. With practice and patience, you will find yourself becoming more confident in tackling even the most complex texts. Good luck! ??

Understanding the Formation of Oil: A Guide for TOEFL Test Takers ??

As a TOEFL test taker, you may encounter various topics in the reading section, including scientific processes. One such topic is the formation of oil, which is both fascinating and complex. In this article, we will break down the oil formation process into clear sections, making it easier for you to understand and remember key concepts. Let’s dive in! ???

1. The Origin of Oil ????♂?

Oil primarily originates from ancient marine organisms, such as zooplankton and phytoplankton. When these organisms die, they settle on the ocean floor and accumulate in sedimentary layers. Over millions of years, these layers become buried under additional sediments. The pressure and heat from this burial process are crucial for transforming organic matter into hydrocarbons, the main components of oil.

2. The Conditions for Formation ??

For oil to form, specific conditions must be met:

• Source Rock: This is where organic material accumulates. Typically, shale is the most common source rock for oil.
• Temperature and Pressure: The right amount of heat (between 60°C and 120°C) and pressure is necessary to convert organic material into oil over geological time scales.
• Time: The process of oil formation takes millions of years, emphasizing the importance of geological time in this natural phenomenon.

3. Migration of Oil ??

Once oil forms in the source rock, it does not remain there. Instead, it migrates through porous rocks until it becomes trapped in reservoir rocks, which have low permeability. This migration is essential because it allows oil to accumulate in significant quantities, making extraction feasible.

4. Trapping Mechanisms ??

Oil traps can take several forms, including:

• Structural Traps: These occur due to geological formations like folds or faults that prevent oil from escaping.
• Stratigraphic Traps: Changes in rock type or porosity can create barriers that hold oil in place.
• Combination Traps: Often, traps involve a combination of structural and stratigraphic features.

5. Extraction of Oil ??

Once oil is located in a reservoir, extraction methods come into play. Common techniques include:

• Primary Recovery: Utilizing natural pressure to bring oil to the surface.
• Secondary Recovery: Injecting water or gas to push more oil out.
• Tertiary Recovery: Employing advanced techniques like thermal recovery or chemical flooding to extract remaining oil.

6. Environmental Considerations ??

The extraction and use of oil raise several environmental concerns. Oil spills, greenhouse gas emissions, and habitat disruption are significant issues that require careful management. Understanding these impacts is vital for anyone studying energy resources and their implications.

7. Vocabulary to Know ??

As you prepare for the TOEFL exam, familiarize yourself with relevant vocabulary related to oil formation:

• Hydrocarbons: Organic compounds made of hydrogen and carbon.
• Permeability: The ability of a rock to transmit fluids.
• Reservoir: A subsurface pool of hydrocarbons.
• Geological Time: The vast timeframe over which geological processes occur.

8. Practice Questions ?

To reinforce your understanding, consider these practice questions:

• What are the primary sources of oil?
• Explain how temperature and pressure contribute to oil formation.
• What types of traps can hold oil in the earth's crust?

By grasping the formation process of oil, you will not only enhance your knowledge for the TOEFL reading section but also gain insight into one of the world’s most critical natural resources. Good luck with your studies! ??
