Most large cities have zoos, but have you ever (be) to a zoo at night? Singapore (have) a Night Safari. It might seem strange to go to a zoo when it's dark. However, if you go to see lions, tigers or (fox) during the daytime, they'll probably be asleep! A lot of animals only wake up at night, so this is the best time (watch) them. At the Night Safari, you can watch these animals in a more (nature) environment than in a normal zoo.
