英语翻译
It is certainly true that the university should give its attendants an advantage when they hunt for a job in the job market,which is the very end that the majority of parents who send their children to universities do have.In that case,they would be less likely to be disappointed.
...is the very end ...do have 是指最后的打算吗?这是一个固定词组吗?能不能再造个句子?
There has always more to learn than schools have time to teach,so inevitably some things and subjects that are considered to be less important must be left out.
请问前半句是不是应该在than后面加个what呢?
Both practical skills and academic skills can be learnt outside school.However,academic subjects are less likely to be learnt outside the formal education system simply because most children do not want to spend their evenings and weekends on learning more than their teachers have told them about such topics.
最后more than 在这里是什么用法?感觉有点像unless.
However,this does not automatically mean the Internet can play all the roles a school can,nor that it can take the place of school education.
...all the roles a school can...这里语法上允许吗?是否可以在写作中这样写?为什么不写成all the roles a school can play?nor 后面为什么有that?
问题有点多,请逐一回答,答案精准可靠的话,我会再加很多分给你的!
