謝謝您的解釋，其實我關於句子結構方面還有一些問題:
比如說我看到一個句子:
One of the most popular literary figures in American literature is a woman who spent almost half of her long life in China, a country on a continent thousands of miles from the United States.
出處有來自這三本書:
我會先抓出句子主幹:
主詞:One of the figures
動詞:is
補語:a woman
One of the figures is a woman
但這樣還不夠解讀句子的意思，我就把其他修飾的東西再一個個加上:
most popular literary 修飾 figures
in American literature 修飾 figures
who spent almost half of her long life in China 形容詞子句修飾a woman
形容詞子句主詞: who
動詞: spent
受詞: life
almost 副詞
half of 形容詞修飾 her long life。her long 修飾 life
in china 副詞修飾動詞spent
a country on a continent thousands of miles from the United States 修飾China
但是當我碰到像該篇托福文章(Biological Clocks)的句子，舉例來說像第一段第一句:
Survival and successful reproduction usually require the activities of animals to be coordinated with predictable events around them
我在分析句子結構的時候，在要抓動詞的時候
我會混淆不知道該看成
require the activities of animals to be coordinated…
->require (someone or something) to (do something)
還是
require the activities of animals ->require 動詞
to be coordinated with…->不定詞片語作副詞修飾require
托福文章很常出現類似這種的片語動詞，讓我常卡住不知道該採取哪種分析方法
還是這種只能靠多看背下來用法而已? 謝謝。
或是遇到像 in relation to 這種不是片語動詞的片語，我也會卡住不知道該怎麼定義它在句子中扮演的腳色
