Dear schoolmaster,

    ……

    That's all. Thank you!

    It's true that many dads in the wild aren't interested in parenting, but there are some that work pretty hard to give their little ones a good start. Maybe one of these dads will make you remember your own dad!

    The male giant water bug doesn't seem to mind a heavy load on his back for his kids. The female puts about 100 to 150 eggs on the back of the male, and then she leaves. Once the female is gone, the male has to look after the eggs. It usually takes one to two weeks for the eggs to hatch. The father giant water bug jumps around to make sure the growing eggs get enough air and water. All this time he can't fly because of the weight of the eggs growing rapidly on his back.

    Now let's turn to the male stickleback fish. When the mother leaves after laying her eggs, the father tends his young. If the young fish go too far away, their father helps with their safe return by carrying them back in his mouth. The male stickleback looks after all his young — as many as 100 — until they can live on their own.

    A similar example can be found in emperor penguins living in cold areas. The male emperor penguin goes without food while looking after his egg until it hatches. For about 62 to 67 days, the egg stays on top of the father's feet, in very cold temperatures that drop down to -39° C. As a result, the father may lose nearly 50 percent of his body weight while waiting for his baby penguin to be born!

    When you take a walk in any of the cities in the West, you can see a lot of people {#blank#}1{#/blank#}(walk) with dogs. It is still true that a dog is the most useful and faithful animal in the world, but the reasons why people keep a dog {#blank#}2{#/blank#}(change). In the old days people used to train dogs to protect themselves against attacks by other beasts. And {#blank#}3{#/blank#}(late) they came {#blank#}4{#/blank#}(realize) that a dog was not only useful for protection,{#blank#}5{#/blank#} willing to obey his master. For example, when people used dogs for hunting, the dogs would not eat what was caught without {#blank#}6{#/blank#}(permit). But now people in the city need not protect themselves against attacks of animals. Why do they keep dogs, then? Some people keep dogs to protect themselves from robbery. But the {#blank#}7{#/blank#}(important) reason is for companionship. For a child, {#blank#}8{#/blank#} dog is his best friend when he has no friends to play with. For young couples, a dog is {#blank#}9{#/blank#}child when they have no children. For old couples, a dog is also their child when their real children have grown up. So the main reason why people keep dogs has changed from protection {#blank#}10{#/blank#} friendship.
