Ⅰ．单句语法填空
1．(2020·浙江卷)Over thousands of years，they began to depend less on __what could be hunted or gathered from the wild，and more on animals they had raised and crops they had sown.
解析：考查名词性从句。句意：在几千年的时间里，他们开始减少对从野外采集的猎物的依赖，而更多地依赖他们饲养的动物和播种的庄稼。分析句子，宾语从句部分缺主语，所以引导词应为“连接代词”。根据句意，此处缺“什么”之意。故填what。
2．(2020·天津卷改编)The student completed this experiment to make come true __what Professor Joseph had said.
解析：考查名词性从句。句意：这个学生完成了该实验，使约瑟夫教授所说的话成为现实。make sth. come true“使……成为现实”，本句中sth. 较长，故放到了come true之后。分析句子结构可知，make后缺宾语，故空格处引导宾语从句且在从句中作had said的宾语因此应用what引导该从句。
3．(2020·江苏卷改编)It is not a problem __whether we can win the battle; it’s just a matter of time.
解析：考查主语从句。句意：我们能否打赢这场战斗不是问题；这只是时间问题。it是形式主语，whether引导的从句是真正的主语。句中not a problem暗示空格处表示“是否”。故填whether。
