Do Animals Think?

As a matter of fact, milk always meets in the stomach a digestive juice which curdles1 it; the curdling2 of the milk is the first step in its digestion3. A similar wrong idea is that fish and ice cream when eaten at the same meal form a poisonous combination.       Still another wrong idea about mixing foods is that proteins and carbohydrates5 should never be eaten at the same meal. Many people think of bread, for example, as a carbohydrate4 food. It is chiefly a carbohydrate food, but it also contains proteins. In the same way, milk, probably the best single food, contains both proteins and carbohydrates. It is just as foolish to say that one should never eat meat and potatoes together as it is to say that one should never eat bread or drink milk.               Think of/ about/over   pest killer   Make fun of sb.   Be engaged in sth.   I am engaged in learning computer.---engagement   Calm/serious   Fog—foggy   Tomb   Stick to—transparent   Sticky tape   Muddy   Batman   Hardly   Hardly did I know their names.   Fashionable   old fashioned   out of fashion   Up-to-date    out-of-date   Vary—various—variety   Boots   Intelligence—intelligent   Wise—wisdom   Be busy doing   Can’t help from doing   Find   Take good care of   Look after   As they are hardworking, hardworking as they are   Their thought must be very busy while they are engaged in these sports.       LESSoN FIVE      TEXT  B                 Do  Animals  Think?       The question has often been asked, Do animals think? I believe that some of them think a great deal. Many of them are like children in their sports. We notice this to be true very often with dogs and cats; but it is true with other animals as well.       Some birds are very lively in their sports; and the same is true with some insects. The ants, hardworking as they are, have their times for play. They run races; they wrestle6; and sometimes they have mock fights together. Very busy must be their thoughts while (they are)engaged in these sports.       There are many animals, however, that never play; their thoughts seem to be of the more sober kind. We never see frogs engaged in sport. They all the time appear to be very grave. The same is true of(prep.) the owl7, who always looks as if he were considering some important question.
