/ spring Emerge healthy and hungry Their fields are protected.

while insects are ready to attack Farmers are happy. farmers’ crops.

Sad:

insects (attack---eat) Happy: farmers (crops---expenditure---insecticide) spiders (survive---shelters---emerge--- fill)

(2)

stronger than steel/

/lighter than a feather/

/as elastic as a rubber bandUses of spider silk: in spacecraft/

/artificial organs like hearts/

/bullet-proof vests

(3)

Uses of spider poison (L35-L40) treat brain disorders in humans T:

From the facts we know spiders are harmless creatures.

Step Three

Consolidation

Summary Spiders are not insects. They survive winter by living in shelters built by farmers. In spring, they eat insects that attack farmers’ crops. They made webs with silk, which is strong, light, and elastic. Scientists plan to use spider silk in spacecraft, etc.

Their poison can be used to treat brain disorder. Therefore, spiders are enemies of insects and friends of humans.

We should try to understand things in nature and not destroy them.
