The spider is very little and clever. Its body is made up of two parts. It has four pairs of legs and eight
little eyes.
The spider loves work. It begins to work as soon as it begins to live. Every spider is a weaver. Even the
youngest spider knows how to weave (编织) its web just as well as the oldest.
The silk of which it makes its web comes from its body. It is like hairs. Many of these hairs come out
at the same time, but they are all formed into one rope of silk. It is so thin that a hundred of them together
are only as thick as a human hair.
First the spider fasten (固定) one end of the silk thread (丝线) to a leaf or to a piece of wood, then it turns
and fastens it to the other end.
When the spider fastens both ends, it can run down the silk and fix some more threads. These are the
cross ropes of the web. Then it weaves other lines round them, and makes about twenty rings.
Then spider works hard and fast, and it finishes its work in less than an hour. The web is then so strong
that the wind cannot blow it away and the rain cannot break it. The purpose of the spider's web is to catch
insects, which are its food.
Insects cannot walk or fly out of the web, because the spider covers it all with something like glue (胶水),
which sticks to anything that touches the web and holds it fast (牢固).
Not all the spiders are the same sort of work to do. Some spiders are masons (泥瓦匠). They build houses
the size of a big thimble (顶针). They make doors in them, which they shut after them when they go in. They
can even fasten the door of the house from the inside, so that no robber can get in.
The garden spider lets thread float in the air till they stick to plants or to the branches of trees. It then uses
these threads as the roads or bridges to cross from one place to another.
