2. 第2题时间状语“thousands of years ago”提示用一般过去时,动词需变过去式;
3. 第3题考查固定句型“It's + 形容词 + to do sth.”,需用动词不定式;

【解析】
1. 固定句型“It's + 形容词 + to do sth.”中,名词danger的形容词形式为dangerous,故填dangerous;
2. 时间状语“thousands of years ago”表明句子为一般过去时,动词change的过去式是changed,故填changed;
3. 固定句型“It's important to do sth.”表示“做某事很重要”,此处需用动词不定式,故填to find;
4. these后需接可数名词复数,动词invent的名词形式是invention,复数为inventions,故填inventions;

1. 单数主语the wheel变复数Wheels,be动词is变are,可数名词invention变复数inventions,故填Wheels are; inventions;
2. 画线部分是目的状语,用Why提问,原句为一般现在时,主语people是复数,加助动词do,故填Why do;
3. It's + adj + to do sth的同义结构为动名词短语作主语,learn about变Learning about,故填Learning about;
