What about something like the following?

use strict;
use warnings;

my %fragments;

while ( my $line = <DATA> ) {
    chomp $line;
    my ( $term, $rest ) = split ' ', $line, 2;
    push @{ $fragments{$term} }, $rest;
}

for my $term ( keys %fragments ) {
    print "There are $term " . ( join ' and ', @{ $fragments{$term} } 
+) . ".\n";
}

__DATA__
big businesses
fast red cars
big movie companies
fast light planes
fast animals
big bad wolves

Output:

There are big businesses and movie companies and bad wolves.
