On the other hand, plants cannot move 29 and do not need to learn to avoid certain things, so this sensation would be unnecessary.
答案：(B) from place to place
【句型】from place to place 固定片語「四處移動」；from door to door（挨家挨戶）、from top to toe（從頭到腳）、from case to case（視情況而定）都不符合這裡「植物無法移動」的語境。
四個選項長得一模一樣，都是 from A to B 的形狀，只差中間換了個名詞，記憶最容易互相干擾。這一題的鑑別度只有 33：線索完全在片語本身認不認得，不必回頭讀上下文，所以它分不太出閱讀的程度——記得的人直接填，沒記得的人也可以從「植物不能移動」硬推出跟地點有關。
先看主詞和動詞：plants cannot move ___（植物不能……移動）。move 後面缺的是「移動的範圍」，from place to place 就是「從一個地方到另一個地方、四處」。再用後半句驗算：and do not need to learn to avoid certain things（也不需要學著避開某些東西）——會移動的生物才需要學著避開危險，植物不動，所以不需要，前後兩件事是同一個道理的兩面。
from door to door（挨家挨戶）：指一家一家拜訪，用在推銷、拉票、送貨（劍橋詞典的說明是走遍一個區域裡的每一戶），主詞得是人。from top to toe（從頭到腳）：講的是全身上下，常見於 dressed in black from top to toe。from case to case（因個案而異）：談的是情況不同、處理方式也跟著不同，與移動無關；這個意思更常見的說法是 case by case 或 on a case-by-case basis。
from place to place（從一地到另一地、四處）、from door to door（挨家挨戶）、from head to toe／from top to toe（從頭到腳）、from time to time（不時、偶爾）、from beginning to end（自始至終）、on a case-by-case basis（逐案、視個案處理）。
Do plants have feelings? There is currently no reason to believe that plants experience pain, because they are devoid of central nervous systems and brains. Animals are able to feel pain 26 they can use it for self-protection. 27, if you touch something hot and feel pain, you will learn from this 28 that you should not touch that item in the future. On the other hand, plants cannot move 29 and do not need to learn to avoid certain things, so this sensation would be unnecessary.
From a physiological standpoint, plants are completely different from animals. They cannot feel pain. Therefore, 30 animals' body parts, many fruits and vegetables can be harvested over and over again without dying.
