• 細(xì)節(jié)題 (Detail Questions)：這些問題關(guān)注文章中的具體信息。例如：“According to the passage, what did the researcher find?”
• 推理題 (Inference Questions)：考生需要根據(jù)文章內(nèi)容做出合理推測,，如：“What can be inferred about the author's attitude?”
• 詞義猜測題 (Vocabulary Questions)：要求考生根據(jù)上下文推測某個單詞的意思,，例如：“In line 10, the word 'exemplify' most nearly means...”
• 句子插入題 (Sentence Insertion Questions)：考生需要判斷某個句子在文章中的最佳位置。
• 總結(jié)題 (Summary Questions)：要求考生選擇最能概括文章或段落的選項,。

二,、備考策略

了解各種題型后，接下來是如何有效備考,。以下是一些建議：

• 多讀英文材料：通過閱讀不同主題的英文文章,，提升你的閱讀理解能力?？梢赃x擇科學(xué),、歷史、文化等領(lǐng)域的文章,。??
• 做真題練習(xí)：通過做托福真題來熟悉題型和考試形式,。記得分析每道題的正確答案及其原因。
• 時間管理：在模擬考試時,，確保自己能夠在規(guī)定時間內(nèi)完成閱讀部分,。一般來說，你需要在60分鐘內(nèi)完成3-4篇文章。
• 詞匯積累：托福閱讀中常見的學(xué)術(shù)詞匯可以通過背誦和使用詞匯書來提高,。你可以嘗試使用閃卡軟件來幫助記憶,。
• 理解上下文：在遇到不懂的單詞時，不要過于糾結(jié),，試著通過上下文理解其含義,。

三、例題解析

下面是一個例題的示例：

Reading Passage:

“The impact of climate change on polar bears is significant. As the ice melts, their hunting grounds diminish, leading to a decline in their population.”

Question: “What can be inferred about polar bears from the passage?”

Options:

• A. Polar bears are thriving in their environment.
• B. Climate change is beneficial for polar bears.
• C. The population of polar bears is decreasing due to habitat loss.
• D. Polar bears have adapted well to climate change.

Correct Answer: C. The population of polar bears is decreasing due to habitat loss.

四,、考試當(dāng)天的注意事項

在考試當(dāng)天,，保持冷靜是非常重要的。以下是一些小提示：

• 提前到達(dá)考場：確保你有足夠的時間進(jìn)行登記和適應(yīng)環(huán)境,。

通過以上的分析和建議，相信你能夠在托福閱讀部分取得更好的成績,。加油,！??

Understanding the Origin of Marine Mammals

As a TOEFL test taker, you might encounter reading passages related to various scientific topics, including the origin of marine mammals. This subject not only fascinates biologists but also provides an excellent opportunity for you to enhance your reading skills. ??

Marine mammals, such as whales, dolphins, and seals, have a unique evolutionary history that traces back to land-dwelling ancestors. Understanding this transition can help you grasp complex biological concepts and improve your TOEFL reading comprehension.

Key Concepts in Marine Mammal Evolution

1. Evolutionary Transition: Marine mammals evolved from terrestrial mammals approximately 50 million years ago. The process began with animals like Pakicetus, which had features suitable for both land and water. ??

2. Adaptations: Over time, these mammals adapted to aquatic life. For example, the development of streamlined bodies and flippers allowed them to swim efficiently. Their respiratory systems also evolved to enable them to hold their breath for extended periods. ??

3. Fossil Evidence: Fossils play a crucial role in understanding marine mammal evolution. For instance, fossils of Ambulocetus provide insights into the transitional features between land and water mammals. ??

TOEFL Reading Tips

When you encounter passages about marine mammals or similar topics, consider the following strategies:

• Skim and Scan: Quickly skim the passage to get a general idea before diving into details. Look for keywords related to evolution, adaptation, and fossil evidence.
• Highlight Key Information: As you read, highlight or underline important facts and concepts. This will make it easier to answer questions later.
• Practice Vocabulary: Familiarize yourself with terms like adaptation, evolution, and fossil. Understanding these words will help you comprehend the text better.

Sample TOEFL Reading Passage

Here is a sample passage to practice with:

Passage: "The evolution of marine mammals from terrestrial ancestors is a remarkable example of adaptation. Early mammals such as Pakicetus exhibited both land and aquatic traits. Over millions of years, adaptations like streamlined bodies and specialized limbs emerged, allowing these creatures to thrive in ocean environments."

Sample Questions

After reading the passage, you might encounter questions such as:

• What is the primary focus of the passage?
• Which feature distinguishes marine mammals from their terrestrial ancestors?
• How did fossils contribute to our understanding of marine mammal evolution?

Vocabulary Building

Here are some vocabulary words related to marine mammals that you should know:

• Adaptation - The process by which a species becomes better suited to its environment.
• Fossil - The preserved remains or traces of ancient organisms.
• Evolution - The gradual development of species over time.

Predicting New Questions

Based on current trends in TOEFL reading comprehension, you might encounter new types of questions focusing on:

• The impact of environmental changes on marine mammal evolution.
• The significance of specific fossil discoveries in understanding evolutionary processes.
• Comparative analysis between marine mammals and other animal groups.

By familiarizing yourself with the origin of marine mammals and practicing your reading skills, you will be better prepared for the TOEFL exam. Good luck! ??
