　　Fast Food

　　Nowadays,_fast_food_is_becoming_increasingly_popular_in_China,_especially_among_children_and_teenagers.

　　There_are_several_reasons_for_its_popularity._First,_it_is_so_convenient_to_get_fast_food_that_it_can_save_a_lot_of_time.You_just_go_into_a_fast_food_restaurant,_order_your_food,_and_your_food_is_ready_in_no_time.Secondly,_its_popularity_also_results_from_the_clean_and_comfortable_environment_of_fast_food_restaurants_and_the_excellent_service_there.

　　However,_fast_food_is_far_from_satisfactory_in_nutrition,_especially_for_the_health_and_growth_of_the_children_and_young_men.Therefore,_doctors_suggest_that_people,_especially_children,_should_eat_as_little_fast_food_as_possible.I_quite_agree_to_their_suggestion._In_my_opinion,_fast_food_is_the_best_choice_when_you_are_too_busy_to_spare_enough_time.And_you'd_better_turn_to_it_once_in_a_while.
