1.Alcohol, hunger, too much talking, breathing through the mouth during exercise-anything that dries the mouth produces bad breath. (1998. 阅读. 1. Text 3)

【译文】酒精，饥饿，说话太多，锻炼时时用口腔呼吸——所有引起口腔干燥的行为都会引起口臭。

【析句】例句1中，首先列举了四个引起口臭的例子，包括名词和动名词，破折号后是主句anything produces bad breath，而主句主语anything后that dries the mouth是定语从句修饰anything。

2. Bottom retail prices-anywhere from 30% to 70% lower than those in Europe and Asia-have attracted some 47 million visitors, who are expected to leave behind $79 billion in 1994. (1998. 阅读. 1. Text)

【译文】美国商品的最低零售价——比欧洲和亚洲任何国家低30%到70%——吸引了约四千七百万游客，1994年有望在美国消费七百九十亿美元。

【析句】复合句。主句是Bottom retail prices have attracted some...visitors。主句中，两个破折号之间的内容anywhere from...Asia作插入语。主句后，who are expected to leave...是定语从句修饰visitors。

3. Home schoolers, oppose the system because they have strong convictions that their approach to education-whether fueled by religious enthusiasm or the individual child’s interests and natural pace-is best. (1998. 阅读. 6. Text 2)

【译文】家庭教育者之所以反对现有的教育体系，是因为他们坚信，他们的教育方式——无论是以宗教信仰还是以孩子个人兴趣和自然发展为动力——都是最好的。

【析句】与例句2结构相似，句子中都有插入语。主句是Home schoolers oppose the system,主句后接着是because引导的原因状语从句because they have strong convictions.that their approach to education is best作strong convictions的同位语，说明convictions的内容。而在同位语中，两个破折号之间的whether fueled by religious enthusiasm or the individual child's...pace作插入语修饰their approach to education。
