【解析】

试题分析：这篇短文中给我们介绍了三个新的发明，这些交通方式都有利于环境，不会造成污染，这样就可以使我们的城市更绿，更适合人们居住。

1.细节理解题。根据短文第一段中A green city is a healthy and pleasant place for people to live in.可知，一个绿色的城市是一个可以让人们居住的，健康的，令人愉快的地方。由此可知选C。

2.推理判断题。根据短文第二段中The Hyperloop plans to run from Los Angeles to San Francisco. With an average speed of 962 km per hour, it is only 35 minutes between the two cities可知，这个高级地铁的时速是962公里，而从洛杉矶到旧金山只需花费35分钟的时间，由此我们可以计算出，两地的距离大约是560公里。故选B。

3.推理判断题。根据短文第三段中And the motor allows bikes to travel up to 50km once可知A的说法是正确的；根据This invention can easily fit onto almost any bike可知B是正确的；根据It can be controlled through your smartphone’s Bluetooth可知D是正确的；根据Smart Wheel is a bicycle wheel with a motor可知C不符合文意。故选C。

4.细节理解题。根据最后一段短语中It is covered with solar panels that can provide energy可知，这个太阳能步道覆盖了太阳能帆板，可以用来发电。故选B。

5.主旨大意题。根据这篇短文中的三个介绍可知，这些公共交通方式都对环境是有利的，不会造成污染，而且这三个新的发明都很现代。故应该选A。
