托福閱讀高難度句子分析

在備戰(zhàn)托?？荚嚨倪^(guò)程中,，閱讀理解部分常常會(huì)遇到一些復(fù)雜的長(zhǎng)難句。這些句子往往包含多個(gè)修飾成分和從句,，給考生帶來(lái)了不小的挑戰(zhàn),。接下來(lái)，我們將通過(guò)一個(gè)關(guān)于魚(yú)類血液溫度交換系統(tǒng)的例句進(jìn)行詳細(xì)解析,，以幫助考生更好地理解和應(yīng)對(duì)類似的句子,。

原句案例：

(In a countercurrent exchange system), the blood vessels (carrying cooled blood from the flippers) run close enough to the blood vessels (carrying warm blood from the body) (to pick up some heat from the warmer blood vessels); thus, the heat is transferred (from the outgoing to the ingoing vessels) (before it reaches the flipper itself).

結(jié)構(gòu)解析：

修飾一： (In a countercurrent exchange system)，介詞短語(yǔ)
中文：在逆流交換系統(tǒng)中

修飾二： (carrying cooled blood from the flippers),，非謂語(yǔ)動(dòng)詞,，修飾the blood vessels
中文：攜帶來(lái)自鰭部的冷血

修飾三： (carrying warm blood from the body)，非謂語(yǔ)動(dòng)詞,，修飾the blood vessels
中文：攜帶來(lái)自身體的溫血

修飾四： (to pick up some heat from the warmer blood vessels),，非謂語(yǔ)動(dòng)詞
中文：以便從溫血管中獲取熱量

修飾五： (from the outgoing to the ingoing vessels)，介詞短語(yǔ)
中文：由流出的血管到流入的血管

修飾六： (before it reaches the flipper itself),，從句
中文：在到達(dá)鰭部之前

參考翻譯：

在逆流交換系統(tǒng)中,，攜帶來(lái)自鰭部的冷血的血管與攜帶來(lái)自身體的溫血的血管非常接近，以便從溫血管中獲取熱量;因此,，在到達(dá)鰭部之前,，熱量通過(guò)流出的血管到流入的血管完成了轉(zhuǎn)移。

When preparing for the TOEFL exam, understanding various scientific concepts can be beneficial, especially in the reading and listening sections. One interesting topic that often appears in academic discussions is the temperature exchange system in fish blood. This system plays a crucial role in how fish adapt to their aquatic environments. Let’s dive into this fascinating subject! ??

What is the Temperature Exchange System?

The temperature exchange system in fish blood is a remarkable adaptation that allows these creatures to regulate their body temperature effectively. Unlike mammals, fish are ectothermic, meaning their body temperature is largely influenced by the surrounding water temperature. However, some species have developed specialized systems to maintain a more stable internal temperature, which can enhance their performance and survival. ??

How Does It Work?

Fish utilize a counter-current heat exchange mechanism in their blood vessels. This system involves arteries and veins running parallel to each other. Warm blood from the fish's core travels towards the gills, while cooler blood returning from the gills moves in the opposite direction. By the time the warm blood reaches the gills, it transfers some of its heat to the cooler returning blood. This process helps to minimize heat loss to the colder water, allowing the fish to maintain a higher body temperature than the surrounding environment.

Why is This Important?

Maintaining a stable body temperature is vital for fish, as it affects their metabolic processes, including digestion, growth, and reproduction. For instance, fish that can keep their body temperature slightly above the ambient water temperature often exhibit faster growth rates and improved reproductive success. This adaptation is particularly advantageous in colder waters where temperature fluctuations can be significant.

Examples of Fish with Advanced Temperature Exchange Systems

Some notable examples of fish that exhibit this remarkable adaptation include tuna and some species of sharks. These fish are known for their ability to swim long distances at high speeds, which requires a high metabolic rate. The efficient temperature exchange system enables them to sustain their energy levels and thrive in various marine environments.

Implications for Climate Change

As climate change continues to impact ocean temperatures, the ability of fish to adapt through their temperature exchange systems may be tested. Warmer waters can affect the distribution and behavior of fish species, potentially leading to shifts in ecosystems. Understanding these adaptations can provide insights into how fish populations might respond to changing environmental conditions. ??

Conclusion

For TOEFL students, grasping the concept of the temperature exchange system in fish blood not only enhances your knowledge of biology but also prepares you for related questions in the reading and listening sections. You may encounter questions like:

• Reading Text: "What is the primary function of the counter-current heat exchange system in fish?"
• Listening Text: "How do certain fish maintain their body temperature in cold waters?"
• Essay Topic: "Discuss the advantages of temperature regulation in fish and its implications for their survival."

By familiarizing yourself with such topics, you can improve your comprehension skills and perform better on the TOEFL exam. Best of luck with your studies! ??

Preparing for the TOEFL can be quite challenging, especially when it comes to the reading section. Here are some high-difficulty reading techniques that can help you navigate through complex passages and improve your comprehension skills. ??

1. Understand the Structure of the Passage

Most TOEFL reading passages follow a clear structure, often including an introduction, body paragraphs, and a conclusion. Familiarizing yourself with this structure can help you locate key information quickly. Look for topic sentences at the beginning of each paragraph, as they usually contain the main idea. ???

2. Skimming and Scanning Techniques

Before diving into detailed reading, practice skimming the passage for a general idea. Focus on the first and last sentences of paragraphs, as well as any highlighted or bolded words. After skimming, use scanning to find specific information related to the questions. This two-step approach saves time and enhances understanding. ??

3. Build Your Vocabulary

A strong vocabulary is essential for tackling difficult texts. Make it a habit to learn new words daily. Use flashcards or apps to reinforce your learning.
