Mr.：There are two things that you'll need to know.

有兩件事你必須知道。

M：What are they?

哪兩件事?

Mr.：The school has three lunch periods, and the kids are divided into three groups to go to lunch.

學(xué)校有三個(gè)午休用餐時(shí)間，學(xué)生分成三組去吃午餐。

M：Wow!

哇!

Mr.：Furthermore, when you are dismissed in the afternoon, you will be divided into two waves.

此外，下午放學(xué)時(shí)，學(xué)生也分成兩批。

M：Two waves?

兩批?

Mr.：The school parking lot is not big enough for all the school buses to come in at one time. So only half the buses come in first to pick up the first wave's students.

學(xué)校停車場(chǎng)不夠大，不能在同一個(gè)時(shí)間讓所有的校車進(jìn)來。所以一半的校車先進(jìn)來搭載第一批的學(xué)生。

M：And the other half come in later to pick up the second wave.

而另一半的校車再進(jìn)來搭載第二批。
