How come you can heart hunder but not see lightning nor see dark gray clouds coming toward you?
By Emily Solomon
In a thunder storm(雷暴雨),we are used to seeing dark clouds with rain and lightning(闪电)followed by thunder .When we don 't see all of those together,it is a surprise.
You can heart hunder without seeing clouds or lightning if the thunder storm is small or if it is far away . Then the sunmay even be shining over your head.And if the sun is bright,you might not see lightning hidden in a cloud .(from Highlights for Children)
