There are hundreds of people in the park.We planted _____ trees last year.
A. hundreds of B. hundred of
C. five hundreds D. five hundred ofthousand, million, billion和hundred的用法相同。2. With so many stars in the universe, are we alone, or is there life out there in space?
宇宙中有这么多星球，我们是孤独的吗？抑或太空中还有其他生命存在呢？
With so many things to do, we have no time to play.
要做的事情这么多，我们都没时间玩了。这里with so many stars in the universe是介词短语，在句中作状语。类似的例子还有：The woman stood there with her hands in the pockets.
那个女士站在那里，手插在口袋里。— Why do you always sleep ______?
— Because I’m afraid of the dark.
A. by yourself B. with the door open
C. with the window open D. with the light on 3. Why has no one communicated with us?
