Answer:
The sun is an extended source of light which is far away from the Earth. The sunlight casts a Shadow of the object, in its path, on the earth. This Shadow has no Umbra but penumbra which is nothing but the shade. There is a sufficient amount of light available to read in the shade. Hence, we are able to read while sitting in the shades.
