Dozens of cities line the Grand Canal. The Yangzhou section is very complex. Yangzhou has a network of waterways, where 【小题1】 （course）built in different dynasties meet with natural waters.

One of the greatest values of Yangzhou's section of the canal 【小题2】 （be）that it has an accurate historical record. It has a long-term impact 【小题3】 economic and cultural exchanges between north and south. These wouldn't have been possible, otherwise. It also set an example for canal 【小题4】 （construct）across China, leading to the final Beijing-Hangzhou Grand Canal,   【小题5】 connects the channels built in different periods.

The canal 【小题6】 （bring）economic prosperity（繁荣, 兴旺）and cultural progress to the city. Yangzhou was, therefore, home to many salt merchants, who built Chinese gardens that remain to this day. The canal was built for the city's economic, cultural and social development. And development, in turn, required canals with 【小题7】 （high）transport capacity. And this history was shown at the Yangzhou China Grand Canal Museum,   【小题8】 （schedule）to open in July.

The Grand Canal's Yangzhou section hosts rich cultural heritage 【小题9】 remains one of the most active parts of the Grand Canal. The city was born with the canal, so the culture of Yangzhou and the waterway are 【小题10】 （actual）one and the same.

That Beijing, together with Zhangjiakou, 【小题1】 (succeed) in getting the chance to host the 2022 Winter Olympic Games in 2015, speeds up the development of Zhangjiakou City.

Word came 【小题2】 the Beijing-Zhangjiakou high-speed railway, 【小题3】 (locate) in North China, is currently under construction, and is expected to be completed by 2021 in preparation for the cities to host the 2022 Winter Olympics. Starting from Beijing North Railway Station and heading west through the Great Wall three times in the capital’s territory, the project is a big challenge, 【小题4】 designers say the explosions needed to dig the tunnels will not have an impact on the structure. The line has a 【小题5】 (long) of 174km as a double tracked passenger dedicated line(双轨道乘客专线), with ten stations situated along   【小题6】 (it) route. Having a 【小题7】 (totally) investment of 31.17 billion yuan ($5 billion), the trip between the two cities will only take 40 minutes, with the train 【小题8】 (travel) at an average of 250 km/h. According to the plan, the high-speed railway will build two branch lines — one is to Yanqing Station and the other 【小题9】 Taizicheng of Chongli, where the Olympic village lies. The full railway, which includes a 70-kilometer section through Beijing, will be completed in one and 【小题10】 half years.

Many people often get 【小题1】 (stick) in traffic jams when they go to work. How tired and angry they often feel! But the problem is that 【小题2】 number of cars is still increasing. And traffic is one of the major 【小题3】 (cause) of global warming and climate change. What's more, some types of cancer are related 【小题4】 traffic pollution. We all know that cars are bad for us. But we are still addicted 【小题5】 cars. Some advice has been given to help people give up cars. For example, we should use public transport or share cars. As we know, up to ninety people can travel in one bus 【小题6】 the same number will need at least eighteen cars. Do your shopping in the shops that are just around the corner instead of 【小题7】 (drive) to the other side of the town. Sharing cars is much 【小题8】 (cheap) and it is kinder to the environment. Let's 【小题9】 (take) action to solve the problem and do 【小题10】 (which) of the things that suit us.
