答案：h--tooth
名詞直接作前置修飾語的時候，應該用單數形式。
2.(toll)from--on
take one's toll on somebody/ something 的意思是“使得……受損失、對……產生不良影響”，如The terrible weather took its toll on my health。惡劣的'天氣對我的健康產生(不良)影響。
dy--blood
bloody和blood都可以作爲定語修飾名詞，但是bloody的意思是“血腥的”。
--may/can
這裏上下文並沒有必然的聯繫，所以用must是不恰當的，應該用比較弱的推測語氣。
(limit)--/
but also和前面的not only 構成並列結構，所以動詞應該是不帶to的不定式。
lete--total
原文的意思是“攝入的卡路里的總量”，表示數量上的總數應該用total，complete側重表示 程度，組成部分的完整性。
--/
seek是及物動詞，直接跟賓語，要和look for 區分開來。
8. concoct--concocting
動詞concoct通過連詞and和前面的modifying、searching並列，所以應該是-ing分詞。
ady--yet
這是一個否定句，所以應該用yet。
--safety
safe是形容詞，它作爲名詞的意思是“保險箱”，所以應該改成safety。
