24、学家们”。2.which根据句法可知,空处所填词引导非限制性定语从句,先行词antioxidants指物,且在定语从句中作主语,所以用关系代词which。3.Generally空处所填词作状语,修饰整个句子,应用副词Generally。4.freedom此处考查give sb. sth.结构,空处作直接宾语,故用名词形式freedom。5.amake a difference to是固定短语,意为“对有影响/起作用”。6.wrote空处为句子的谓语,根据空前的“the noted 16th-century Swiss physician”可知,句子时态用一般过去时,故此空填wrote。7.co
25、nsumed空处为非谓语动词,wine与consume之间构成被动关系,所以此空填过去分词consumed作后置定语。8.beneficialbe是系动词,后接形容词作表语。be beneficial to意为“对有益”。9.from/of句意:Roger Corder教授已经花了数年研究红酒对健康有好处的证据。空处应填介词from或of,表示“来自”或“的”之意。10.convinced分析句子可知,句中says后接省略了that的宾语从句。宾语从句主语为he,谓语动词为is,空处应填形容词convinced构成固定句型“sb.is convinced that.”。convinced作形容词时,意为“确信的,深信的”。
