You see,in a plant's stem（茎）there are several hundred “water pipes （管道）”that bring water from soil all the way up to the leaves. When the ground turns dry, it becomes harder and harder for plants to do this.

　　In very hot days, plants have to get any water that it can. Scientist Robert Winter has found out that when plants can get no water, their “water pipes” snap （发出断裂声）. When that happens, the whole plant vibrates （振动） a little.

　　Robert knows that healthy, well-watered plants are quiet. He also knows that many insects （昆虫）prefer attacking dry plants rather than healthy plants.

　　Colours are really made by reflected（反射）light. We see colours because most of the things reflect light. Something is red, for it reflects most of the red light. In the same way, if something is green it reflects most of the green light. If something reflects all light, it is white.

　　Some of the light is reflected and some is taken in（吸收）and turned into heat（热能）. The darker the colour is, the less light is reflected, the more light is taken in. So dark-coloured clothes are warmer in the sun than light-coloured clothes.
