不知道你现在上几年级，先帮你这么改一下吧，你看看合理吗

语法错误好像没有。
但我可以指几点可以改的地方。
1.He
found
that
listening
is
more
difficult
.这句话，最好改成最高级，
He
found
that
listening
is
the
most
difficult.你本身句子并没有错误，但根据前后文，和其他2项做下比较，因为用最高级比较好点。
2He
couldn't
understand
every
word。还有这句话，
这话的意思是，他不懂任何一个词语。我想，你本身并不是想说这个意思吧。应该是，他听不清楚大多数的词吧
应该改成这样，He
couldn't
listen
very
clearly.意思是，他听不太清楚。
