▲网友的判断和理解都是正确的！这种转换表达了相同的意思。

It looks like Mary is too tired to walk on. 看起来本玛丽已累得走不动了。

It looks like the weather is changing for the worse. 看来天气变得更糟了。

首先需要说明的是：

1. like 不仅可以用作介词，而且，在非正式英语中还可以用作连词，后接从句，如网友给的这两个例句。这时，like 的意思相当于as if。现在，这种用法已经比较普遍，尤其是美国英语。

2. 在It looks like (=as if)...结构中，it 是引导词，没有实际意义，指某种情况或现象，like 引导表语从句。这时，我们可以用实际主语替换it，转换成以下两句，以下句子中的like，同样可以换成as if：

Mary looks like she is too tired to walk on.

The weather looks like it is changing for the worse.
