Lesson 30 Review　第30課　課程復(fù)習(xí)

There is ice on the pond, and the mill wheel can not go round.

The boys are all out on the ice with their skates.

I will let you and Tom try to skate；but do not fall, for you will be hurt.

Look！here come the cars.

John and Nat try to skate as fast as the cars go, but they cah not. John has had a fall.

The girls are not on the pond；but some of them have skates which roll on the foor.

池塘結(jié)冰了，磨坊水輪不能來回滾動。

男孩們都在外面滑冰。

我想讓你和湯姆試試滑冰，但是不要摔倒，因為你們會受傷的。

看！火車過來了。

約翰和納特想滑得和火車一樣快，但是他們做不到。約翰摔了一跤。

女孩們不在池塘邊；但是，她們中的一些人在地板上滑旱冰。

火車跑得真快啊！

你能看見火車嗎？
