托福考試閱讀長難句對大家來說簡直是噩夢，要怎麼分析這些惱人的長難句呢?大家在看長難句的時候，多思考，一個句子為什麼這麼長，常見的修飾成分到底有哪些?其實不多，連詞、非謂語動詞、介詞以及同位語或插入語。下面是小編分享的長難句分析範例，希望能幫到大家!
But detractors maintain that the terraces could also have been created by geological activity, perhaps related to the geologic forces that depressed the Northern Hemisphere far below the level of the south, in which case they have nothing whatever to do with Martian water. (TPO8, 44)
detractor /dɪ'træktɚ/ n. 貶低者，誹謗者
terrace /'tɛrəs/ n. 臺地，梯田
depress /dɪˈprɛs/ vt. 使(某人)憂愁, 消沉;將(某物)壓下, 拉下;使(尤指貿易)不活躍, 不景氣
hemisphere /'hɛmɪsfɪr/ n. (地球的)半球;(大腦 的`)半球
參考翻譯：
但是反對者認為這些臺地可能是由地質活動創造的，也許和把北半球壓得比南半球低很多的地質力量有關係，在這種情況下，臺地就和火星上的水就沒任何關係了。
這個句子的主要修飾成分就是插入語和從句，大家務必想清楚，每一個修飾成分修飾的是什麼，才能看清楚這個句子的結構。
But detractors maintain (that the terraces could also have been created by geological activity), (perhaps related to the geologic forces)( that depressed the Northern Hemisphere far below the level of the south), (in which case they have nothing whatever to dowith Martian water). (TPO8, 44)
分析：
修飾一：(perhaps related to the geologicforces)，插入語
中文：和地質力量有關
修飾二：( that depressed the Northern Hemisphere far below the level of the south) ，從句，修飾the geologic forces
中文：把北半球壓得比南半球低很多
修飾三：(in which case they have nothing whatever to do with Martian water) 從句，修飾前一句話
中文：在這種情況下，臺地就和火星上的水就沒任何關係了。
主幹：But detractors maintain (that the terraces could also have been created by geological activity)
