《柯林斯英汉双解大词典》

One hundred (of the children) have already been placed with foster families.

有一百名（儿童）已经获安排领养。

谓语必须是is，固定搭配。

one hundred，two hundred，three hundred…等等，表示整百的，后面的be动词用单数is。英语中表示时间，距离，金钱和重量等作主语时，谓语动词要用单数。如，

Last year, I went to join one thousand and five hundred metre race.

去年，我去参加了一千五百米的赛跑。
