【正确答案】：1.shown/showed 2.provides 3.living 4.babies 5.safety 6.threatened 7.suitable 8.helpful 9.nearly 10.survival
【题目解析】：1.解析：空格前是have，后面需要加动词的过去分词，共同构成现在完成时，而show的过去分词是shown或者showed。所以答案是shown或showed
2.解析：根据空格所在句子成分分析，主语是they way，谓语动词是provide，所以需要把provide改成第三人称单数，答案是provides
3.解析：空格后是名词things，所以需要用形容词来修饰名词，答案是living
4.从空格后面的them，说明baby不止一个，所以需要改成复数babies
5.move sb to some place 表达把某人转移到某处，所以to后面需要加名词，把safe改成safety
6.to be+过去分词构成动词不定式的被动语态，所以需要把threaten改成threatened
7.空格后是名词food，所以前面需要改成形容词，答案是suitable
8.空格前是are，后面如果所给是动词，要么把动词+ed改成被动，要么+ing改成进行时态，要么把动词改成形容词，根据句意，需要改成形容词，答案是helpful 9.near当副词时表达在附近，而此句上下文表达的是大概大约的意思，所以需要改成nearly
10.空格前是their，后面需要加名词，所以把survive改成survival
