by itself的用法详解
英语单词by itself的用法讲解
by itself是英语中一个常用的表达，意思是“单独，独自地”或“独立，无帮助”。这个短语可以表达两个意思：一是强调单独性，表明某个人或物体没有受到任何外部干涉；二是表明某个人或物体自己的能力还不到位，需要帮助。例如：
1. 他们通过自己的努力完成了这项任务，没有受到外部帮助。
The task was accomplished by themselves, without any outside help.
2. 他还不够成熟，所以不能独立完成这项工作。
He's not mature enough to do the job by himself.
因此，by itself 既可以用来强调独立性，又可以用来表达相对的依赖性。同时，by itself 还可以用作“仅仅，只是”的意思，用来表达某件事情只是个小例子。例如：
1. 他们只是简单地做了一个试验，这只是一个小例子而已。
They just did a simple experiment, which is just a small example by itself.
2. 这只是一个小的改变，但它可能会带来重大的影响。
It's just a minor change, but it could have huge implications by itself.
总之，by itself 用来强调单独性或者独立性，也可以用来表达“仅仅，只是”的意思。
