解析

【分析】
本题为用括号内所给词的适当形式填空,解题思路为:先分析每个空格在句中的语法成分,确定所需词性;再结合句意,对括号内的词进行对应词性的变形;最后验证变形后的词是否符合语法和句意要求。
【解析】
1. 空格前是形容词great,需修饰名词,press的名词形式为pressure,故填pressure;
2. 此处表示“头疼”,head对应的名词是headache,构成固定短语have a headache,故填headache;
3. 由“经常忘填名字”可知Eric是粗心的,care的形容词形式careless(粗心的)符合句意,故填careless;
4. 修饰名词nose需用形容词,run的形容词形式为runny,构成固定搭配runny nose(流鼻涕),故填runny;
5. enjoy oneself是固定搭配,意为“玩得开心”,主语是we,对应反身代词为ourselves,故填ourselves。
【答案】
1. pressure 2. headache 3. careless 4. runny 5. ourselves
【知识点】
词性转换;固定短语;反身代词
