1. (2018·重庆) 阅读下列材料，从A、B、C、D四个选项中选出最佳答案。

B

    National Smile Month is the largest and longest mouth health activity in the UK. Starting in 1977, it is celebrating its 42nd birthday from May 14 to June 14 this year.

    The British are known for their bad teeth because they have too many sugary (甜的) foods and drinks. It seems that most of them don't often show their feeling. They neither smile nor cry. But this is NOT true. The British like to smile as much as anyone else. They just don't want to show their bad teeth.

    Brush your teeth at least twice a day, cut down sugary foods and drinks, and visit the dentist often. With the three messages, the organizers (组织者) hope that a month of smiling will make people all around the UK realize the importance of good teeth and be confident enough to open their mouths to smile.

    One interesting activity is for the British to enjoy the fun photos with short stories behind. Seeing the smiling faces and reading the interesting stories, everyone can't help smiling! You're welcome to send yours with big smiles online.

    Smiling is not only good for you but also good for those around you, even if you do have a few bad teeth. This makes National Smile Month a great idea!
