[3끊어쓰기] TOEFL Reading : Seagrasses 1  

Many areas 

of the shallow sea bottom 

____________are covered 

with a lush growth 

of aquatic flowering plants 

___________adapted 

to ________live submerged in seawater.

These plants 

_________are collectively called seagrasses.

Seagrass beds __________are strongly influenced

by several physical factors. 

The most significant ____________is water motion: currents and waves. 

For any given seagrass systems exist 

in both sheltered 

and relatively open areas, 

they _________________are subject to differing amounts 

of water motion.

For any given seagrass system, 

however, 

the water motion ____________is relatively constant.

Seagrass meadows 

in relatively turbulent waters 

(apt to be made of flat)_______________tend to ___________form flat,

extensive carpets.

The seagrass beds, 

in turn, 

___________dampen 

wave action, 

particularly if the blades ____________reach the water surface.

This damping effect ___________can be significant 

to the point where just one meter 

into a seagrass bed, 

the wave motion ____________can be reduced to zero.
