题目分析:
破折号中的using Web sites, public meetings, and mass mailings是插入语,不影响主干结构,因此本题的主干为:
The organic food industry has organized a successful grassroots campaign that has convinced the Department of Agriculture
选项分析:
A选项:定语从句that have convinced the Department of Agriculture的先行词应为a successful grassroots campaign,即,这个草根运动劝服了the Department of Agriculture。因此,由于campaign是单数,所以应将have convinced改为单数动词has convinced。另外,also是副词,表示“也”,和并列连词and之间在语意上重复。
B选项:Correct. 本选项在语法和逻辑上均是正确的。
C选项:介词短语in convincing the Department of Agriculture需改为定语从句 that has convinced the Department of Agriculture。这是因为,介词身后只能是动名词短语,而动名词短语在字面上没有主语。例如,我们说,a bag for sleeping,这个词的意思是,睡袋。这完全不等同于a bag that sleeps(一个bag没法睡觉)。在本题语境下,发出convince这个动作的肯定是a successful grassroots campaign,即,草根运动劝服了政府,因此必须用定语从句。
D选项:并列连词and不能换为as well as,as well as使mass mailings与前两项变为从属或递进关系,而在逻辑上,网站,公众集会,广发邮件应是单纯的并列关系。
E选项:介词短语in convincing the Department of Agriculture错误同(C)。
A:also是副词, and also都是可以的;have convinced找不到先行词;
C:描述名词的时候,一个用定语从句、一个是介词短语,它们的主要区别在于定语从句的连词是没有任何含义的,而介词短语的介词作为定语的话,介词in, on, at等都具有自己的含义;
in convincing,在说服里面…
D:as well as可以作连词或者副词,as well as有强弱关系,后者更弱势一些
E:in convincing 在说服里面,错
