难以被证实。Some people may not agree with this opinion but they also cannot prove that they are right. 有些人可能不同意这种看法，但是他们也不能证明他们是正确的。
In a trial, a judge must decide which eyewitnesses to believe and which not to believe. 在审判中，法官必须断定哪些证人可以相信，哪些证人不能相信。The judge does not consider what each eyewitness looks like or where that person lives or works. 法官并不考虑证人的长相如何，也不考虑这个人住在哪里，在哪儿工作。He/she only cares about whether the eyewitness has given true information, which must be facts rather than opinions. 他(她)关心的只是目击者是否提供了真实的信息，这些信息必须是事实而不是个人观点或看法。 This kind of information is called evidence. 这种信息就叫做证据。
A FACT OR AN OPINION?
一个事实还是一个观点
What is a fact? Is it something that people believe? No. A fact is anything that can be proved. For example, it can be proved that China has more people than any other country in the world. This is a fact.
什么是事实？是一些人们相信的东西吗？不！事实是可以被证明
的任何事。例如，可以证明中国人口比世界上任何其他国家的人口都要多。这是一个事实。
Then what is an opinion? An opinion is what someone believes is true but has not been proved. So an opinion is not good evidence in a trial. For example, it is an opinion if you say “Cats are better pets than dogs”. It may be true, but it is difficult to prove. Some people may not agree with this opinion but they also cannot prove that they are right.
那么什么是一个观点？一个观点是人们相信那是真的但还没有被证明的。所以一个观点在一个审判中不是一个好的证据。例如，如果你说“猫是比狗好的宠物”这会是一个观点。这可能是真的，不过很难去证明。一些人可能不同意这个观点不过他们也不能去证明他们是对的。

在一场审审讯（审判）中，一个审判官一定要去决定相信哪个目
击者哪个目击者不应该相信。这个审判官不会去考虑每个目击者的长相或人们在哪里居住或工作。他/她只关心目击者是否会提供真实的信息，信息一定是事实而不是观点。这类的信息被称为证据。
