在托福閱讀考試中,，長難句的理解往往是考生們面臨的挑戰(zhàn)之一。本文將通過分析一段關于行星云層構成的句子,，幫助考生提升對復雜句子的理解能力,。

Sentence Analysis

This sentence's difficulty lies in the embedded relative clause within the subject clause. The word it serves as a formal subject, while the actual subject is the primordial cloud of dust and gas introduced by the clause that follows. The relative clause beginning with from which modifies the preceding cloud. The main verb of the subject clause is had, with a composition as its object, followed by the phrase somewhat similar to that of Jupiter serving as a post-modifier. Additionally, the phrase that of Jupiter refers back to composition.

Vocabulary Explanation

The word hypothesis means "假設," and its verb form hypothesize can be used as follows: It is hypothesized that...

Primordial denotes something that is "原始的."

Condense means "濃縮;凝結," for example: He condensed his speech to half its original length.

Composition indicates "組成," such as in the sentence: He’s doing research into the chemical composition of plants.

Jupiter refers to "木星," the fifth planet from the Sun and the largest in the solar system.

Sentence Translation

There exists a hypothesis that all planets are believed to have condensed from a primordial cloud of dust and gas, with a composition somewhat similar to that of Jupiter.

• 識別從句：長難句中常常包含定語從句、狀語從句等,。在上述例子中,，“which had been meeting for days”是一個定語從句，用來修飾主語,。
• 簡化句子：將長句拆分為幾個短句,，有助于理解。例如,，把“the committee, which had been meeting for days, finally reached a decision”簡化為“the committee reached a decision”可以更清晰地抓住主要信息,。

2. 注意連接詞

連接詞在長難句中起著重要作用，它們幫助我們理解句子之間的關系,。常見的連接詞包括：

• and, but, or：表示并列關系,。
• because, since, as：表示原因。
• although, though, while：表示讓步或對比,。

例如,，在句子“Although the weather was bad, we decided to go hiking.”中，連接詞“although”提示我們這是一個讓步關系的句子,，盡管天氣不好,，但我們?nèi)匀粵Q定去遠足。
