2--Okay, where do we start?

1--The best place to start is the roof.

2--The roof? Isn't that dangerous?

1--Don't be afraid. As long as we're careful, we'll be alright.

2--But I'm afraid of heights.

1--I'll be there. Like I said, we'll be okay.

2--Okay, I trust you.

1--A good roof is very important. If it leaks, it can ruin the interior.

2--Yes, I know. Remember Uncle Joe's house?

1--I sure do. Let's get started.

2--Okay. I'm ready.

1--是开始工作的时候了。

2--好吧,我们从哪里开始?

1--最好的起点是屋顶。

2--屋顶吗?那不是很危险吗?

1--不要害怕。只要我们小心,我们会没事的。

2--但我恐高。

1--我会与你同在。就像我说的,我们会没事的。

2--好吧,我相信你。

1--一个好的屋顶是非常重要的。如果漏水,它可以毁掉室内。

2--是的,我知道。还记得乔叔叔的房子吗?

1--我当然记得。让我们开始吧。

2--好吧。我准备好了。
