单项选择题
在甲市，电动自行车一方面方便了居民的出行，另一方面又增加了城市交通压力，形成交通隐患。在甲市居民中形成“放开”和“限制”电动自行车的两种意见。
以下各项如果为真，都只能支持上述某一种意见，除了( )。

B．甲市发生的多起交通事故都是电动自行车占道行驶引起的
C．由于电动自行车出行便利，致使甲市的公交车营业额递减
D．电动自行车厂商是甲市的主要利税大户
答案
参考答案：C
解析： 评价型题目。题干有两方面意见：电动自行车能方便居民，所以应“放开”；电动自行车增加城市交通压力，所以应“限制”。
A项改善道路交通网，削弱了后一种意见，属于支持“放开”意见；B项多起交通事故由于电动自行车引起，属于支持“限制”意见；D项从经济方面支持“放开”意见。只有C项前半句支持“放开”意见，后半句从经济方面支持“限制”意见，故答案选C。

caused the deaths of up to 100,000 fish over a 20-mile stretch of the Arkansas River near a dam in Ozark, 125 miles west of Beebe. The fish were discovered on December 30. Stephens said the commission expected results on the fish tests in probably a month. Since almost all the fish were one species -- bottom-feeding drum, Stephens said, the test was very important. Stephens also said: “The events do not appear related.” Both that section of the river and the air at the site of the bird deaths were tested for toxins(毒素). Beebe is a town of about 4,500 people located 30 miles northeast of the state capital.
