B(2023.江苏连云港一模)
① The natural world is colourful with humans,plants and animals showing different colours.Human skin can be many different colours and it changes with the sun,our feelings,or our health.This is because of pigments(色素),
which reflect light and make what the eye sees as colours.
So,when we feel excited or angry,our heart sends more blood to the face and the pigments in the skin become red.
② Plants also have pigments.Colours play an important role in their life.The bright colours of flowers catch the attention of insects,which then carry their pollen(花粉)
from one flower to another.Bees can see colours we cannot,
and they follow these to the inside of the flower.Without bees visiting flowers in this way,many plants would die out.
③ Animals also use colours for their own need.They protect
themselves with different colours in order not to be seen by
predators(捕食者).The snowshoe hare,,for example,a type of
wild rabbit,changes colours with seasons for r this reason.During summer it is brown,and in winter it is white so that it can hide in the snow.However,some animals use the colour as a warning to frighten predators away.Bright colours such as yellow and red are often used in this way.
④ So,we can see that there may be many different
reasons and uses for colours in the natural world.Some uses of colours in nature ren iain unknown,but one thing is for sure.Colours not only make our planet beautiful,but they are also necessary for our planet to live on.
