今昔对比题干中有时间&比较词
思路：
1.科技方面，可以写网络/app/WeChat、交通工具比如高铁，医疗技术比如HPV （宫颈癌cervical cancer）。
2.政策方面，生育政策中的计划生育，二胎（two child）。教育政策，九年义务教育（compulsory education），实在想不起来，政策也可以编造。
3.lifestyle改变。
4.思想意识改变。

不同意
Personal preference/academic burden;
Financial burden
Other way：alternatives to study:books;videos;
同意
Acquire/gain/obtain knowledge,考虑课程是否有等级限制
Discover what they interested in（需要考虑年龄层次，因为默认大学生选择的课程都是自己感兴趣的，所以大学生不适用）
Care for animals:
题干中强调“最好”是不现实的，所以一律使用不同意。切入点从最高级入：可以是虽然不是最好，但也有好处；正因为有缺点，所以不是最好；还有更好。所以思路是非最高级的优点，最高级的缺点，更好的选择。
优点顺着题目意思即可： caring for animals is conducive to the sense of responsibility.
缺点需要不能与“更好”相反，这点会影响“更好”那一点：it may pose a threat to children’s health or even lives./money
更好：从animals角度出发，可以是照顾他人；volunteer work：nursing home|do household chores/tasks
因果关系类题目，题干中有表示因果的词，比如so...that。

不同意时可以同时反对原因&结果
反对原因：no necessarily
反对结果：moving to new place not mean to ...new friends
