Riddles or brain teasers are a great way to practice your reading comprehension.  Here is one from Einstein (try to figure it out):

GARDENS

Five friends have their gardens next to one another, where they grow three kinds of crops: fruits (apple, pear, nut, cherry), vegetables (carrot, parsley, gourd, onion) and flowers (aster, rose, tulip, lily).

They grow 12 different varieties.

Everybody grows exactly 4 different varieties. 

Each variety is at least in one garden.

Only one variety is in 4 gardens.

Only in one garden are all 3 kinds of crops.
