BEIJING---No Car Day was first started by 34 cities in France on September22, 1998. It was started to protect the environment. By now, more than 1,000 cities around the world have had a No Car Day.

The first No Car Day in China was in Chengdu in 2001. Other cities, including Taipei, Shanghai and Wuhan, also support( 支持) the day.

In Beijing, more and more people are joining in the activity. It asks drivers to leave their cars at home for one day each month and walk or ride a bike to work. It also calls on Beijingers not to use cars on June 5 ( World Environment Day ).The slogan for the day is, “ If we drive for one less day, we can have one more nice day.”

So far more than 200,000 drivers have shown their support “ We can’t control the weather, but we can choose not to drive,” said Wu Zonghua, a car club chairman. Beijing is trying to have 238 blue sky days this year. In the first quarter of this year, Beijing only had 52 blue sky days. This was 11 days less than the number for the same period last year.

下图是齐齐哈尔“8·4”中毒事件的照片

齐齐哈尔“8·4”事件，引出了罪恶之源———日本关东军“516”部队。

据《齐齐哈尔军事史》记载，在1931年以后，齐齐哈尔市的东郊八里岗，曾经驻扎着一支与“731”部队肩负同样任务的防化部队，这就是侵华日军关东军陆军化学研究所，代号“516”。这支部队当年极其隐蔽，打着科学研究的旗号，从事化学武器研究、试验和制造，用中国老百姓活身体做试验，犯下的罪行遗留到今天。由于“516”部队藏匿较深，目前记载它的史料甚少。当年，这支部队共有250多人，下设5个课，主要从事化学武器研究、开发、教育训练和化学战的试验。1945年8月15 日，日本投降后，这支部队的许多机密资料被带回日本，而大部分装备和毒剂弹遗留在中国。(据新华社)
