课文详注  Further notes on the text

1．hundreds of, 数以百计的。

这是用来表示不定数量的复数形式。类似的结构还有thousands of（数以千计的）， millions of（数以万计的）。但必须注意：说 five hundred（五百，500），six thousand（六千， 6，000），two million（两百万，200万）等时，hundred, thousand, million 这些词因为之前有具体数字而本身不加-s。

2．at the race, 观看比赛。

这里的at是“出席”、“在某场合”的意思。

3．Our friends Julie and Jack were there, too.我们的朋友朱莉和杰克也去了。

Julie and Jack是 Our friends的同位语。

4．car number fifteen, 第 15号车。

在表示编了号的东西时，可以用基数词表示顺序：
