It is a truth which people of different ages undstand music differently.答案说是强调句，需把which改成that 。为什么不可能是主语从句？我觉得整个从句是主语，和it形式主语换，《不同年龄的人理解音乐是不同的》是主语。2。强调句去掉强调结构，a truth people of different ages undstand music differently.也不通呀
It is a truth that people of different ages undstand music differently.=That people of different ages undstand music differently is a truth.主语从句

英文投诉信如下，供您参考（最好根据自己的实际情况，可以考虑用谷歌翻译修正一下。Dear SirMadam,I recently bought something from your website and sent to a freight fowarder called XX-XX (此处填转运的英文名称） asking them to send to my relatives who are in China. But by now, the parcel still didnt arrive. During this period, I have sent many emails to them asking them to send asap, but without any positive feedback. I have a lot of friends who also used this forwarder; they have suffered the same problems. From the information I know, there might be hundreds or even thousands victims. I am afraid this company might be a cheater who is using US territory to cheat buyers property and money. I have written to BBB and other US agency who might help on this case. If there is still no help, I am going to report this crime. I am writing this email to you to inform about this dishonest and cheating behaviors, hoping you to block this forwarder to prevent them from further cheating. This forwarders full information is as below:(此处填这个无良转运的英文名称） (freight forwarder)2401 Ogletown Rd (suite number is different for identifying different buyer), Newark, Delaware, 19711.More buyers might write you emails about similar problems. Please block this address to prevent more cheating to happen. Thanks. 你的姓名拼音转过来的，如果有用，请给分，谢谢！

1.先行词做从句的主语的定语从句. 2.强调句两者如何区分？有例子吗？
最关键的区别是定从中的that 做句子成分，做主语；而强调句中 it is。。。that。。中，that不做句子成分，必须和it is +强调本分+ that构成一个整体，除掉it is，和that之后，还可以组成一个句子。如： the bike that was repaired belonged to me. 定从，that指代the bike it is the bike that belonged to me. 强调句，除去it is， that 之后，the bike belonged to me.还是一个完整句子。
