Answer the questions（根据短文内容回答下列问题）

Copenhagen, the capital of Denmark, is famous for its biking culture. Its people have biked to work since the 1880s. And recently, it has shown again that it is one of the world’s great biking cities.

For the first time, there are more bikes than cars in the heart of the city, reported The Guardian. It has found 13,100 more bikes than cars in the city center over the past year. In the last 20 years, the number of bikes used has risen by 68 percent.

This is mainly because of the huge efforts（努力）that the local government have made to create a bike city. Since 2005, a large amount of money has been spent on biking, and the city now has several new bridges only for biking and walking.

Bikes are also becoming more and more popular in China. An increasing number of people are cycling instead of driving to school, to their workplace or to tourist attractions. Public bike rental（出租）services have also been introduced in many cities, including Beijing, Hangzhou and Changchun.

The introduction of Mobike, a new public bike rental system-which started in Shanghai in April and came to Beijing on Sept 1-brought the use of bikes to a whole new level. After Scanning（扫描）the QR code（二维码）on the bike, you can ride the Mobike’s orange bikes to your destination. It is far more convenient than the old bike rental system. New payment methods such as Alipay and WeChat are also supported by the service.

Despite this, it’s still not easy to ride bikes in Chinese cities. Because cars usually take up bicycle lanes（车道）,bikers often have to ride next to cars. However, Copenhagen is much friendlier to bikes. Lanes are built to encourage cycling. Traffic lights are timed for bicycle speeds.

For example, Cycle Snake, a high orange bike lane, allows fast bikers to go in both directions. In the mid-afternoon during the summer, bikers can see the daylight between two nearby buildings. It makes riding a bike even more enjoyable.

When Qian Xuesen was three years old, his father got a job in the Ministry of Education in Beijing, so he and his family came to Beijing. Qian Xuesen graduated from Shanghai Jiao Tong University in 1934. In 1935, he went to the United States for study. In 1950, he heard that the new China had been founded, so he began to try his best to go back to his motherland. The American government tried to stop him from his journey, but he succeeded in going back in 1955.

Since 1958,Dr. Qian had devoted all his life to China’s aerospace science and technology and made great achievements.
