例7:After about 40 minutes of shopping, most people stop struggling to be rationally selective, and instead began shopping emotionally—which is the point at which we accumulate the 50 percent of stuff in our cart that we never intended buying.
解析:這是一個經典的長難句,總字數多達40個單詞,甚至比英語(一)翻譯中的絕大多數句子都要長。其中“stop …, and instead began …”屬于并列謂語,“which … at which … that …”是三個定語從句嵌套在這一個句子中。
