ä二、精典名题导解
选择填空
1.The warmth of ____________sweater will of course be determined by the sort of ___________wool used.（NMET 2001）
A．The ; the B．the ; / C．/; the D．/; /
解析：答案为B。第一空格为特指，交待the warmth的内容，第二空格为泛指，the sort of wool used所用羊毛的种类。此题有三点需注意：①正确理解sweater 这一句词在句中的类别。②掌握determine在句中作“决定”、“取决于”这个意思。③掌握定冠词表特指的基本用法。
2.Most animals have little connection with_________animals of___________different kind unless they kill them for food.（NMET 2000）
A．the … a B．/ … a C．the … the D．/ … the
解析：答案为B。名词复数表类别，其前不用冠词，故第一个空格不填冠词，表不定概念的“一种”，“某种”要用不定冠词a。要准确掌握冠词表类别的三种表达方式和不定冠词常用的几种情况，见前面要点考点聚
焦内容。
3.Paper money was in___________use in China when Marco Polo visited the country in __________thirteenth century.（NMET1999）
A．the … / B．the … the C．/ … the D．/ … /
解析：答案为C。题中in use是固定搭配，意为“在使用”，use为抽象名词，其前不用冠词。后者是序数词前用定冠词the。要牢记一些固定搭配如in use、under construction（在建设中）、in debt（欠债）、come to power（执政）、on fire（着火）、at table（用餐）、out of work（失业）等。 |
