M ost people dislike spiders.
They think spiders are gross.
But spiders are very helpful to
people. Spiders eat insects, and they
eat a lot. One spider can eat over
1,000 times its weight in insects in
one year. That means without
spiders, there would be far too many
insects in the world. They would eat all of our food and our lives would be
really bad.
Spiders help us in other ways too. Spiders make silk for their webs. This silk
is very strong and very light. We can make ropes from it. These ropes are
very strong. Mountain climbers sometimes use them . We also use spider
silk in hospitals. Even a spider’s poison can be helpful. We make some
medicines out of spider poison. So, the next time you see a spider, don't kill
it. It is one of our best helpers!
English Usage
• next time + subject + verb~
So, the next time you see me, say hi to me!
• Without + noun, subject + verb(would, could)
Without air, we could not live a minute.
