在高考英语语法填空中，对名词的考查主要涉及可数名词的复数，名词所有格及词形变换。
1.（2019年全国一卷） In recent years some Inuit people in Nunavut have reported report increases in bear sightings around human settlements , leading to a _______(believe)that populations are increasing.
参考答案: belief 在句中做leading to 宾语，根据前面冠词a 名词 ，后面是that 从句（同位语），通过构词法把动词变名词——词形变化。
2. （2019年全国三卷）When they were free from work, they invited us to local events and let us know of an interesting _______ (compete) to watch, toghter with the story behind it.
参考答案：competition 根据前面of确定后面是宾语，interesting形容词修饰名词，所以根据构词法变成名词——词形变化
3.（2018年全国1卷）Two of the authors of the review also made a study published in 2014 66 _______ showed a mere five to 10 minutes a day of running reduced the risk of heart disease and early deaths from all 67_______(cause).
67题考查名词单复数：根据前面介词from 宾语 ，all 修饰名词，所有的原因，不止一个，所以答案是: causes
4.（全国2018年2卷）This switch has decreased __________ (pollute) in the country's major lakes and reservoirs and made drinking water safe for people.
根据分析:谓语动词decreased后接名词作宾语，所以根据构词法把动词pollute 变成名词：pollution
- （全国2018年3卷）I'm a ________ (science) who studies animals such as apes and monkeys. 根据分析：空格部分是谓语am 之后作表语，由于有a ,所以可以确定这边是填名词，题目给的也是名词，这里是表人的科学家：所以根据构词法变成：scientist.
