Are some people born clever and others born stupid? Or is intelligence developed by our environment and our experiences? Strangely enough, the answer to both these questions is yes．To some extent our intelligence is given us at birth, and no amount of special education can make a genius（天才）out of a child born with low intelligence．On the other hand, a child who lives in a boring environment will develop his / her intelligence less than one who lives in rich and varied surroundings．Thus the limits of a person’s intelligence are fixed at birth, but whether or not he / she reaches those limits will depend on his / her environment．This view, now held by most experts, can be supported in a number of ways．
It is easy to show that intelligence is to some extent something we are born with．The closer the blood relationship between two people, the closer they are likely to be in intelligence．Thus if we take two unrelated people at random from the population, it is likely that their degrees of intelligence will be completely different．If on the other hand we take two identical twins, they will very likely be as intelligent as each other．Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth．
Imagine now that we take two identical twins and put them in different environments．We might send one, for example, to a university and the other to a factory where the work is boring．We would soon find differences in intelligence developing,and this indicates that environment as well as birth plays a part．This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all, are likely to have similar degrees of intelligence．

Have you ever wondered why different animals or pests have their particular colours? Colours in them seem to be used mainly to protect themselves．
Birds, especially seagulls, are very fond of locusts, but birds cannot easily catch locusts because locusts change their colours together with the change of the colour of crops．When crops are green, locusts look green．But when crops are ripe, locusts take on exactly the same brown colour as crops have．Some other pests with different colours from plants are usually easily found and eaten by their enemies．So they have to hide themselves in terror for lives and appear only at night．
If you study the animal life in any part of the world, you will find the main use of colouring is to protect themselves．Bears, wolves and other beasts move quietly through forests．They are usually invisible to the eyes of hunters, because they have the colour much like the barks of trees．
An even more strange act remains to be noticed．A kind of fish living in seas can send out a kind of very black liquid when it faces danger．While the liquid spreads over, its enemies cannot find it, and it immediately swims away．Thus, it has existed up to now though it is not powerful at all．
