1、_____a summer afternoon,I eat a cake.
2、A storm is coming _____the South China Sea.
3、In spring, there are many nice flowers ____the island.
第一题不是
追答那就是on a summer afternoon.呵呵,afternoon 前面有个修饰的成分,可以根据前面的内容写为on.
其实两个都是可以的,这是成句:In a summer afternoon, the sky was so blue and grass was so green.一个夏天的午后天空很蓝,小草很绿。我和小伙伴一起去亮晶晶的海里潜水。
但是on更准确一些吧!用on就肯定没有错了!
at 呢?
追答at 不行啊。
