"I have to admit" is an expression that we use when you're going to say something that maybe you don't want to say — you don't want to tell the truth. “I have to admit”是当你要说你可能不想说的事情——你不想说实话的时候会用到的一种表达。

In fact, there's also an expression, "to tell the truth." 事实上，还有一个“to tell the truth”的表达。

So, I have to admit means I have to say — to tell the truth. 因此，“I have to admit”是“我必须承认——说实话”的意思。

"By this time," meaning by 10:30 — "by this time, I'm beat." “到了这时，”也就是晚上10:30——“到了这时，我疲惫不堪了。”

To be beat, "beat," means to be very tired. “To be beat”是“非常累”的意思。

Someone says, "Oh, I'm beat," they've been working all day or they've, like me, been watching television all day, and now I'm beat — I'm tired. 有人会说，“哦，我累坏了，”他们整天都在工作或者他们像我一样，看了一天的电视，所以现在我疲惫不堪了——我累坏了。

Of course, I don't watch television all day, just part of the day! 当然，我不会整天都看电视的，只是一天的部分时间而已啦!

Well, my wife is also beat. 嗯，我妻子也疲惫不堪了。

In the story I say, "I'm beat, and so is my wife," meaning my wife is also very tired. 故事中我说，“I'm beat, and so is my wife，”意思是“我妻子也累坏了”。

"She cleans up when I've finished up." “当我洗完之后她开始洗漱。”

Once again, you see those two word verbs. 又见到了这些两个字的动词。

To clean up is, in this case, to clean your face, to brush your teeth; to get yourself clean is to clean up. “To clean up”在这里是“洁面，刷牙”的意思;让自己变干净就是“to clean up”。
