【题目】B

On Lunar New Years Eve on Feb 18, 2015, Beijing had a good day. PM2. 5 levels were below 50. However, the nice day ended with firework celebrations at night.

In the first hour after the start of the celebration, PM2. 5 levels rose to 500 in certain parts of the city, with the average across the city around 400.

According to the China National Environmental Monitoring Center, on Lunar New Years Day, air pollution reached dangerous levels in 201 Chinese cities, because of fireworks, with more than 40 of them seeing serious pollution. As a result, the debate on whether to ban (禁止) fireworks during the Spring Festival is also heating up.

Sina surveyed 3,000 Internet users, and results show that only 38 percent of the people support setting off fireworks, and 60 percent are against it.

I support a ban on fireworks, a netizen (网民) nicknamed ann019 said. Lighting fireworks can only bring problems: air pollution, disturbing sleep, causing fire and exhausting sanitation workers (环卫工人).

Others thought it to be hard to ban traditions, and lighting fireworks during holiday seasons wont cause lasting pollution.

Some, however, suggest a moderate (温和的) way to solve the problem.

As a tradition, fireworks absolutely add to the festivals happiness. They shouldnt be banned totally, commented netizen Tracy on the China Daily online forum (论坛). But the time /span>should be reduced. For example, it can be allowed just during New Years Eve, the first day of the Lunar New Year and the Lantern Festival.
