Research has also shown a relationship between high levels of fat in the diet and cancer.

答案：
1.teeth--tooth
名詞直接作前置修飾語(yǔ)的時(shí)候，應(yīng)該用單數(shù)形式。
2.(toll)from--on
take one's toll on somebody/ something 的意思是“使得……受損失、對(duì)……產(chǎn)生不良影響”，如The terrible weather took its toll on my health。惡劣的天氣對(duì)我的健康產(chǎn)生(不良)影響。
3.bloody--blood
bloody和blood都可以作為定語(yǔ)修飾名詞，但是bloody的意思是“血腥的”。
4.must--may/can
這里上下文并沒(méi)有必然的聯(lián)系，所以用must是不恰當(dāng)?shù)�，�?yīng)該用比較弱的推測(cè)語(yǔ)氣。
5.to(limit)--/
but also和前面的not only 構(gòu)成并列結(jié)構(gòu)，所以動(dòng)詞應(yīng)該是不帶to的不定式。
6.complete--total
原文的.意思是“攝入的卡路里的總量”，表示數(shù)量上的總數(shù)應(yīng)該用total，complete側(cè)重表示 程度，組成部分的完整性。
7.for--/
seek是及物動(dòng)詞，直接跟賓語(yǔ)，要和look for 區(qū)分開(kāi)來(lái)。
8. concoct--concocting
動(dòng)詞concoct通過(guò)連詞and和前面的modifying、searching并列，所以應(yīng)該是-ing分詞。
9.already--yet
這是一個(gè)否定句，所以應(yīng)該用yet。
10.safe--safety
safe是形容詞，它作為名詞的意思是“保險(xiǎn)箱”，所以應(yīng)該改成safety。
