Comparing of the Two Companies

Reading Comprehension

Passage 1

5 Spiders produce three basic types of webs. The sheet web is a two

dimensional layer of threads seemingly laid out at random. The space web

is a three- dimensional, wispy structure. The orb web, by far the most

familiar, is the two- dimensional cartwheel pattern.

Of the 30.000 spider species, some 6.000 are orb spinners. For three

10 Decades Dr. Peter N. Witt has studied orb spinners, especially a species

called Areneus diadematus, and their webs. Witt is a German-born medical

doctor and self- taught arachnologist, whose passion is to understand the

ways of spiders. Witt has delved deeply into the behavior of spiders and

vastly expanded our knowledge about orb spinners and their webs. Some

15 of his findings have even amazed other arachnologists.

"We have actually compared human building activities to spider

building, and we find an enormous amount of parallet between the two,"

Witt says. For one thing, just like their human counterparts in the building

trades, orb spinners erect a form of removable scaffolding as they weave

20 their webs.

Orb spinners are solitary creatures who dwell one to a web. The web

is home, food source, and mating ground, and it is guarded aggressively.

When a male arrives at mating time, the courtship ritual is an intricate set

of advances and retreats until the female is finally won over and no longer

25 tries to kill her would- be lover.

Orb spinners each weave a new web every day, working in the predawn

darkness and executing the distinctive pattern of concentric circles and

radial lines in a half hour or less. "There is nothing as important as web

building, because without the web there is no food," Witt says.
