Question

to make a good fist impression is what Laura does

to make a good fist impression is what Laura does best怎么错了

Answer 1

在to make a good fist impression is what Laura does 中，fist 讲不通，fist ，”拳，拳头“含义; 把fist去掉，to make a good impression is what Laura does 就讲通了，意思是Laura(劳拉）要做的是留下好印象。
或者把fist 改为first，位置放在does之后，to make a good impression is what Laura does first,意思是 Laura(劳拉）首先要做的是留下好印象。
