【解析】

本文為說明文。一項研究中，那些吃更多有機食品的人患癌癥的幾率更低。然而，一些科學家指出，這項研究并不能證明有機飲食能降低癌癥發(fā)病率，他們呼吁進行更多由政府資助的長期研究來證實這一結(jié)果。他們認為，吃有機食品的好處的證據(jù)一直缺乏，更重要的是，如果人們想要預防癌癥，只要多吃水果和蔬菜，不管這些產(chǎn)品是否是有機的。

【1】句意：一項研究中，那些吃更多有機食品的人患癌癥的幾率更低。此處為定語從句，先行詞是those（那些人），關系詞在從句中做主語，應使用關系代詞who引導。故填who。

【2】句意：該研究跟蹤調(diào)查了7萬名成年人，其中大多數(shù)是女性，歷時五年。根據(jù)空前70,000可知，此處應使用名詞復數(shù)。故填adults。

【3】句意：食用有機水果、蔬菜、乳制品、肉類和其他食物最多的女性患乳腺癌的幾率下降得尤其明顯。此處修飾形容詞big，應使用副詞，particularly“特別地”。故填particularly。

【4】句意：購買有機食品的人相信有機食品對他們的健康更有好處。convince“使確信”，be convinced“相信；確信”。此處描述的是目前的狀態(tài)，應使用一般現(xiàn)在時。故填are convinced。

【5】句意：他們認為，吃有機食品的好處的證據(jù)一直缺乏，更重要的是，如果人們想要預防癌癥，只要多吃水果和蔬菜，不管這些產(chǎn)品是否是有機的。分析句意及句子結(jié)構(gòu)可知，此處是同位語，連詞在從句中不做任何成分，應使用只起連接作用的that引導。故填that。
