Y_小卷_Y - 试用期 一级 的解释something做先行词时定语从句的that不能省略不错
但这道题更合理的解释是
to learn ＿we want to learn and to think for ourselves.
注意后半句to think for ourselves,think是及物动词,需要宾语,这里应选 what,既是we want to learn 的宾语,又是think的宾语.
如果要该成定语从句应该是
something that we want to learn and something that we think for ourselves.
如果理解为 and 连接两个不定式 to learn and to think 一起做want的宾语,语法没错,意义是不对的.因为不可能是 want to think
something that we want to learn and to think for ourselves.
所以 to think 不是want的宾语,而是前面learn的宾语从句,作为一个句子,它需要自己宾语what.
至于您的第二个问题先行词

1先行词是不定代词
I'll read you someting that is worth listening to.
2先行词是形容词的最高级或序数词

He give me the very book that i want.
4先行词有last next
Let's take the next train that is espress train.

6先行词有who
Who that has sympathy( 同情心)can't laugh on the occasion.
7先行词既有人又有物
