1. Pedestrians, drivers, and road conditions are all to blame.

请问为何不是 Pedestrians, drivers, and road conditions are all to be blamed.

【答】Pedestrians, drivers, and road conditions are all to be blamed. 也可以说，但不如原句符合英语习惯。又如：

She is to be praised, not to be blamed.

她应该受表扬，不应该受责备。

People who circulate false news are to be blamed.

散布流言者该受遣责。

We were both to be blamed, if you insist.

如果你一定要这么说，那我们双方都有错。

【说明】在表示将来意义的“be + to do 结构”中，有时候主语跟不定式是被动关系，但习惯上，有些动词的不定式使用主动语态。例如：

The house is to let.

This car is to rent.

That boy is not to blame.

为了理解方便，我们可以变通思维，把不定式理解为定语性质就好懂了，如：

This is the house to let.

That is the car to rent.

He is not the boy to blame.

2. One of these officers is Ed Williams. He and ten other officers are on special duty.

请问为何是 ten other 而不是我们通常说的 other ten ? 

【答】该问题涉及限定词的排序。

如果说话者对other 不特指，那么数字在先，other 在后，即：ten other officers（10个另外的警官；另外的10个警官）

如果说话者对other 特指，即前面有the时，那么数字在后，tht other 在先，即：the other ten officers（那另外的10位警官）。你的句子没有the，不是特指那10位警官，故不可颠倒顺序。

现在，以数词three 为例，比较以下各句：

【以下例句为特指】如：the other three children

1. He has to share his bath water with the other three children in the family.

他得和家里的其他3个孩子共用洗澡水。
