37 Now I am making a cut at this angle in this bit of wood. The blade is going through the wood. This is my knife. This is the blade of my knife. l am making a line on the wood. I am making a line with a pencil. This is the pencil. This is the line.

现在我在这块木头上从这个角度切一个口。 刀刃穿过了木头。 这是我的刀。这是我的刀刃。 我在木头上画一条线。 我正在用铅笔画一条线。 这是铅笔。就是这条线。

38 "Keep on the line when you are cutting. Don't go off it." Oh! You are going off the line! The cut is not on the line. That is bad! The cut is off the line. You did that! You gave a push to the table.

38“切的时候不要挂断。 不要离开它。”哦!你要掉线了！刀口不在线上。 这太糟糕了！剪断线了。 你做到了！你推了一下桌子。

39 No, I did not! Your knife went off the line. Yes. It went off the line. Do it again! It's not very bad. Here is the line. And here is the cut. a straight line a bent line Tom is making another attempt. That is better. The cut is straight. The blade of the knife went straight. Good!

不，我没有！你的刀从绳上掉下来了。 是的。它出了线。 再来一次！不是很糟糕。 这是台词。这是切口。 一条直线一条弯曲的线汤姆正在作另一次尝试。 这样好多了。切口是直的。 刀刃直了。 好!

40 Now I have these two bits of wood. I will put them together like this. There is the roof of the house. Now I will put the two parts of the roof together with nails. These are nails. I will make a hole through this part of the roof into the other part of the roof.

现在我有这两块木头。 我会像这样把它们放在一起。 这是房子的屋顶。 现在我要用钉子把屋顶的两部分钉在一起。 这些是钉子。我要在屋顶的这一部分打一个洞，通到屋顶的另一部分。

41 Tom is making the holes for the nails. Now he is putting the nails in with his hammer. Now the two parts of the roof are together. These are the nails. The roof is ready. Is it strong? Oh yes, it is very strong.

41汤姆正在给钉子打洞。 现在他正用锤子把钉子钉进去。 现在屋顶的两部分合在一起了。 这些是钉子。屋顶准备好了。 它浓吗？哦，是的，它很烈。

42 Don't do that! Oh, now it is broken! But you said, "It is very strong!" It wasn't strong. I will make it stronger. Give the roof to me, please. I'm giving it to you. Is this line long? This line is longer. Is this bit of wood strong? This bit of wood is stronger.

不要那样做！哦，现在它坏了！但你说：“它很坚固！”它不坚固。 我会让它变得更强。请把屋顶给我。 我把它给你。这队长吗？ 这条线比较长。这块木头结实吗？ 这块木头更结实。
