【知识拓展】various是由动词vary（变化）派生而来的形容词，它的副词形式是variously。variety是名词，意为"有变化"，用a variety of表示"各种各样的；多种多样的"，后接复数名词，可与various互用。如：

3. charge

【课文原句】They all charge money for admission, and for the rides and shows in the park. (P33)

I'll charge you five dollars.

How much do you charge for a haircut？

charge还可以表示"把......归咎于(to, on, upon)；告发；在控告(with)"。如：

Bob was charged with the murder, but he refused to admit it.

The doctor in charge told us to be calm.
