By far, the most 【小题1】(technology) challenging railway ever built was probably the Qinghai-Tibet Railway, completed in 2006, which connects Xining to Lhasa. The railway was first planned in the 1950s, but the technical difficulties were too much 【小题2】 (overcome). It was not until 1984【小题3】the first 814-kilometer section of the railway, from Xining to Golmud, was completed.

The biggest issue was the permafrost(冻结带)-frozen earth. In the summer, usually melting at a fast speed, the top layer of the permafrost turns to mud,【小题4】(make) the ground unstable. A【小题5】(various) of solutions were used to get around this. In some cases, railway bridges 【小题6】(build). In other cases, engineers installed pipes under the ground to keep it frozen during the summer. Finally, in some areas, it was impossible to build the railway over the permafrost, 【小题7】engineers tunneled through it.

It is hoped that the experience of building the Qinghai-Tibet Railway can be used in【小题8】 new project, linking China with Pakistan. This railway【小题9】(travel)1,000 kilometers through the Pamir Mountains, which are nicknamed the Roof of the World. Building such a railway will be【小题10】(doubt) a technical challenge. It has not yet been announced when construction on this project will start.

People often get 【小题1】 (stick) in traffic jams. They arrive at work or school, stressed out, tired and 【小题2】 (annoy). Over the last two decades, the number of cars on the road 【小题3】 (go) up by 25% in Britain, and vehicle accidents have also increased greatly, 【小题4】 result in lots of deaths. Besides, too much traffic means too much air pollution.

【小题5】 (keep) such a bad tendency under control, we ought to take action 【小题6】 (immediate) so as to make a difference. Instead of 【小题7】 (drive) our cars, we can walk or ride a bike for short journeys. 【小题8】 addition, we can use public transport or share our cars with others. Also, we are supposed to think 【小题9】 we set out. Is it necessary for us to go there? Can we buy 【小题10】 (thing) in the shop around the corner? In this way, we can contribute a lot to our Mother Earth. So, don’t just sit around and complain! Do whichever of these things that suit you.

“Let’s take a high-speed train to Taiwan. The dream 【小题1】 (realize) in 2035.We will enjoy the scene at Penghu Bay together. And visit the Ali Mountain and Riyuetan Lake.” These are lines from Traveling to Taiwan in 2035, a song 【小题2】 has gone viral on social media.

The song alludes to a ride on a Beijing-Taipei high-speed train, which 【小题3】 (mention) in the 13th Five-Year Plan (2016-20).

Upon the release of the latest outline for China’s National Comprehensive Transportation Network Plan, Taipei, in the island of Taiwan, 【小题4】 (include)in the layout of one of the main routes of the travel plan 【小题5】 (conduct). In fact, with the mainland section of the railway 【小题6】 (complete), the stretch from Fujian province to Taipei across the Taiwan Straits is also to be built.

The railway, when built, will link compatriots on both sides of the Straits, and they are waiting for 【小题7】 completion.

As a response to the song, Zhu Fenglian, the spokesperson of Taiwan Affairs Office of the State Council said along with 【小题8】 a song Take High-speed Railway to Taipei she heard 【小题9】 (previous), they reflect the good wishes of people on both sides of the Taiwan Straits to realize the vision of the high-speed railway from Fujian to Taipei. “I hope that the two sides of the Taiwan Straits will enjoy more convenient exchanges and enjoy 【小题10】 (beautiful)scenery and delicious food. I believe that this wish will certainly come true,” said Zhu.
