decide作动词表示“决定做某事”时,需要用不定式to do。比如: - He decided to help you. - He decided to make a cake. - He decided to go swimming.
原句中之所以没有使用不定式,是因为原句用that引了从句,然后从句中用he从新当了主语。比如,上面三句我写的例句可以改写为: - He decided that he would help you. - He decided that he would make a cake. - He decided that he would go swimming.
decide to do sth. 决定去做某事的固定词组搭配。 decide 是动词,后面接做某事时要加to;如果加从句,就要在decide后面加that, that 后跟一个完整的句子。 这道题是把复合句转换成简单句,decided that he would... = he decided to do
