     McDonnell, who has made oil drilling off Virginia's coast, one of his administration's top tasks,

flew to Houston on Monday to advertise the benefits of offshore drilling at a national conference.

He told reporters before he left that he does not want to postpone drilling but to learn from the

accident off Louisiana's coast.

     "What we do as Americans is that we find out what went wrong and how can we do things

better, " Mc Donnell said."I think that's the spirit of American people."

     President Obama announced in March that Virginia will become one of the first East Coast

states to drill offshore for oil and natural gas.Companies could conduct exploratory drilling in

Virginia's waters 50 miles off the coast late next year or early in 2012.

     In Virginia Beach, the state's largest city and one that relies heavily on tourism, Mayor Will

Sessoms said he would be worried if the timetable was not changed.Sessoms supported drilling

and helped the city pass a resolution (决议) in favor of it, in part to help the tourism industry by

keeping the cost of gas down.But, he said, the Louisiana accident was a wakeup call.

     "It's alarming to me, " Sessoms said."It gives me great concern."

     Obama swore Friday that no expansion of offshore oil drilling would take place until investigations

into the Louisiana accident were complete.

     Virginia's officials, who support drilling, said they agree that drilling should be delayed.Sen.Mark

Warner said it was "appropriate" for Obama to delay offshore projects.McDonnell said he wants to

see a full investigation into the Louisiana accident, but he still thinks that drilling could begin off

Virginia's coast as soon as next year or early 2012.

     McDonnell has also said that drilling off Virginia's coast would create thousands of jobs, as well

as lessen US dependence on foreign oil.

     A recent explosion and fire on an exploratory well in the Gulf (海湾) of Mexico left 11 workers

missing and dead.Crude oil (原油) has been leaking into the gulf since, inching closer to the coasts

of Louisiana, Alabama and Mississippi.

     The accident confirmed the worst fears of environmental groups and people already worried that

possible spills (溢出) could harm plants, animals, and tourism.
