Gorillas (find) are found
in several countries in Central Africa. They are about
1.6 metres tall, and they (cover)
with black or brown hair. Gorillas' lives
(spend) in groups. Each group has five to ten gorillas in it. The gorillas
in a group (walk)
about 0.5 to 1.0 km per day, looking for food. They
(not eat)
all the leaves in one part of the forest before moving on;
some leaves (leave)
on the trees and plants.
At night gorillas (sleep) in nests; these nests
(make)
of branches and leaves. The number of gorillas living in Africa
today (not know)
but it is certain that this number is getting smaller.
Why? Because in the countries where the gorillas (live)
more and more
trees (cut down) every year.
