Table Recovery

Hi,
I want to drop my emp table,and get back my emp table.
i've used this following query to backup my database 'test1'

backup database test1 to disk='e: est1.bak'

drop database test1

restore database test1 from disk='e: est1.bak'


Processed 160 pages for database 'test1', file 'Test1' on file 1.

Processed 1 pages for database 'test1', file 'Test1_log' on file 1.

RESTORE DATABASE successfully processed 161 pages in 0.041 seconds (32.168 MB/sec).

If i use this query i can get back my original database.
main thing is i want to drop my particular table like emp or dept
but i couldnt recover my particular emp table.the following error will come when i try to
execute drop table test1.dbo.address


backup database test1 to disk='e: est1.bak'

drop table test1.dbo.address

restore database test1 from disk='e: est1.bak'


Msg 3159, Level 16, State 1, Line 1

The tail of the log for the database "test1" has not been backed up. Use BACKUP LOG WITH NORECOVERY to backup the log if it contains work you do not want to lose. Use the WITH REPLACE or WITH STOPAT clause of the RESTORE statement to just overwrite the contents of the log.

Msg 3013, Level 16, State 1, Line 1

RESTORE DATABASE is terminating abnormally.
