48、 the view that such violent games can cause propensity for violence while others think that those games are only created for fun.In my opinion, such games do lead to a tendency of violence to some extent.

51、确实会导致暴力倾向。一方面，学生很容易被这些游戏中的一些暴力行为所误导，因为他们还不够成熟，不能辨别对错。因此，他们可能会在现实生活中模仿这些行为。另一方面，一些学生可以在游戏中做一些在现实生活中被禁止而在游戏中被允许的事情，在游戏中他们逐渐发展出了暴力的品质，在与他人发生冲突时更容易做出攻击性的行为。总之，我认为我们应该减少花在暴力游戏上的时间，做更多有意义的事情来充实我们的生活。8. 问答题：For this part, you are allowed 30 minutes to write on the topic Changes in the Way of Transportation

56、层出不穷，人们的生活方式也随之改变。运输方式的变化如下。首先，随着科技的发展，运输价格比以前便宜了很多。此外，与传统的购票方式相比，交通应用程序和网站让乘客无需外出特定售票处就可以在线订票。此外，高速铁路逐渐取代了老式的绿色列车，这可以极大地提高旅客在旅途中的舒适度，缩短旅途时间。在我看来，交通方式的变化主要体现在好的方面，作为生活在互联网时代的幸运旅客之一，能够获得在线交通服务，我不禁感叹：这是最好的时代。9. 问答题：Ships are often sunk in order to create underwater reefs （暗礁） perfect for scuba diving
