解析

【分析】
本题为用所给词的适当形式填空,需结合词汇的词性、固定搭配、句意及语法规则分析:1. 考查不可数名词的用法;2. 考查“one of + 可数名词复数”的固定结构;3. 考查介词后接名词的规则;4. 考查形容词的否定形式,需结合句意判断;5. 考查名词形式的转换,定冠词the后需接名词。
【解析】
1. research作“研究”讲时为不可数名词,无复数形式,some可修饰不可数名词,故填research;
2. “one of + 可数名词复数”表示“……之一”,wonder是可数名词,需变为复数形式,故填wonders;
3. 介词in后需接名词,deep的名词形式为depth(意为“深度”),故填depth;
4. 由后半句“他总是准时”可知,他迟到是“不寻常的”,usual的否定形式为unusual,故填unusual;
5. 定冠词the后需接名词,measure的名词形式为measurement(意为“尺寸,度量”),故填measurement。
【答案】
Ⅰ.1.research 2.wonders 3.depth 4.unusual 5.measurement
【知识点】
名词的数、词性转换、形容词的否定形式
