题目：（你是否同意学生在大学应该学习非常难的甚至得不到高分的课程）
（Students should choose some difficult or challenging classes in college an university even though students cannot get the top grades or marks in them. Do you agree or dis agree with the statement. Give the specific reasons and examples to support your position.？）
开头：
Have you ever considered why we need to study in the university? Have you ever thought about what we can get in the classes? Have you ever confused which kind of knowledge can be used after graduating? If you have never thought of such questions, you would never know which courses are available to you.

University is a place where can provide courses of study to help students to prepare for professions and careers. So what we need in university are some courses which are not just difficult or challenging but useful.

分论点:
1    学习有用的知识可以让学生自信
2    学习有用的知识可以让学生在毕业以后找到合适的工作

貌似第一段有点多余……不确定……

第二种开头：
"Knowledge is power", but which kind of knowledge shall we obtain from the class in university? University is a place where can provide courses of study to help students to prepare for professions and careers. So what we need there are some courses which are not just difficult or challenging but useful.

其实最简单的开头写法就是


交代背景(吊rater胃口):教育进入新时代,能力培养很重要,大学里头给学生提供了各种各样的课程....(这里吹1-2句,可以用各种方式,你写得那些问句也可以用点在里头,关键是要把rater的眼球吸引过来)

交代问题:在大学里有人喜欢选择有挑战性的课,而这种课容易得低分.

你的观点:同意或者不同意,并把主要的分论点说出来(可选)

中间插入一些模板. 开头就OK了,而且也不会走题

非常感谢~~~~
除了这个我不知道说什么了…………

我觉得开头从大往小了写是最好的。首先是充字数，其次能帮助理解和表达出观点。
中文思路：社会要不断进步，就要攻克许多难题——有了攻克难题的能力才能在job market 有竞争力——在大学里学习很难的课程有利于提高我们自己，处理复杂情况的能力。——所以即使分数很低，学习难的课程对于一个学生来说也是很重要的。
