The Writers' Strike：Making the Best of the Worst

By now you are probably feeling the effects of the TV writers’ strike---the decision of television writers to stop working. With few new TV shows, I present to you a list of shows available on DVD worth your viewing time to keep you going during this painful period.

Arrested Development is one of the funniest and most clever shows ever to have appeared on network TV. With a most perfect cast(全体演员), the show sets out to cover the daily happenings of the Bluth family, a group of selfish staff who manage to still put family first.

For more comedy goodness, I recommend one of the sharpest comedies to have ever broadcast, 30 Rock. Starring Tina Fey and Alec Baldwin, two stars with impressive comic timing, the show gives you a glimpse into the making of a sketch show (幽默短剧),similar to Saturday Nigth Live, from the funny writers to the self-centered cast all the way up to the boss.

If you are looking for something more serious, or perhaps Friday Night lights might be more to your liking. If you are a fan of football, this show is probably for you. If you are a fan of great drama, both soapy and serious, this show is probably for you, If you are a fan of good-looking people, this show is definitely for you .

If those shows were not enough for you, might I recommend a show with a more heart-pounding excitement? The Amazing Race, after twelve seasons, still remains one of the most exciting shows on TV. Teams of two travel the globe with little to no money and experience far-out adventures in an attempt to remain the last team standing.

A．two teams won the amazing race

A．the effects of the TV writers’ strike are great

B．the strike puts TV shows in the worst situation

C．watching DVD is a good choice during the strike
