Question

He was so happy to have a chance to go abroad for further study that he made

list of things _to take_ on the way yesterday.
为什么这样填？请详尽，谢谢！

Answer 1

He was so happy to have a chance to go abroad for further study that he made

此句的主句为He was so happy，“to have a chance”解释happy的原因，“to go abroad”解释“chance”，“for further study”解释go abroad的目的，“that he made”修饰a chance
list of things to take on the way yesterday

这不是一个完整的句子，只能说是个短语。“to take on the way yesterday”修饰list of things

Answer 2

to不定时（to take）做后置定语 ，修饰后面的名词或代词，这里 表示“要带的”东西，还有不明白的可以问我 希望能帮到你
