本题考查对文章细节内容的理解与判断，需将题目描述与原文信息逐一对比。

1. Zhao Xin is studying in the Open University now.

原文明确提到：“I just enrolled at The Open University last month. Now I'm a freshman...”（我上个月刚进入开放大学，现在是大一新生），说明赵鑫现在正在开放大学学习，题目表述正确，答案为T。

2. His major is marketing.

原文指出：“Now I'm a freshman at the School of Social Work. As a social work major...”（现在我是社会工作学院的大一新生，作为社会工作专业的学生），可知其专业是“social work（社会工作）”，而非“marketing（市场营销）”，题目表述错误，答案为F。

3. He is looking after the elderly at a nursing home nowadays.

原文提到：“I used to look after the elderly at a nursing home when I was in middle school.”（我中学时曾在养老院照顾老人），“used to”表示过去的习惯，而非现在，题目“nowadays（如今）”与原文不符，答案为F。

4. He wants to change the world and make it better.

原文结尾：“I want to make a difference in the world.”（我想改变世界），“make a difference”意为“带来改变”，与“change the world and make it better（改变世界并使其更好）”意思一致，题目表述正确，答案为T。

4. He wants to change the world and make it better.

（注：此处题目序号可能重复，根据原文“ I want to make a difference in the world.”，“make a difference”即“改变世界，让世界更好”，表述正确，答案为T。）

5. He is proud of being a social worker.

原文提到：“It gives me a feeling of pride to bring happiness to others.”（给别人带来快乐让我有一种自豪感），结合“I love being a social worker.”（我热爱做社工），可推断他为成为社工感到骄傲，题目表述正确，答案为T。
