As populations increased in large cities in 【小题1】 nineteenth century, building subway lines was a way 【小题2】(move) people from one area of a city to another quickly and efficiently. The first major subway system, the London Underground, 【小题3】(start) in 1873 using steam trains. Subways caught on quickly in London. From 1896, it was changed in favor of an electrical system. Today’s subways around the world now work on 【小题4】(electrical). Passengers can rely on the regular schedule of subway trains while 【小题5】(avoid) traffic on busy city streets.

Two of the world’s earliest subways were built in Paris and New York. When the Paris Metro opened on July 19, 1900, citizens were proud of the 【小题6】(impress) and beautifully decorated station entrances.【小题7】 the first New York subway consisted 【小题8】 only 14.5 kilometers of track in 1904, today, it is the world’s largest subway system.

Today, subways are still popular with passengers. The Tokyo subway is the 【小题9】(busy) in the world, with 3.2 billion riders a year. Close behind 【小题10】(be) subways in Moscow(2.4 billion), Seoul (2.1 billion), and New York City (1.6 billion).

The Suez Canal, 【小题1】 it currently exists, is a 193-kilometer artificial waterway connecting the Mediterranean Sea at Port Said to the Red Sea at Port Tewfik.

This waterway connects the Atlantic and Indian Oceans in a way that doesn’t require a ship heading between Europe and Asia 【小题2】 go around Africa or wait for the ice to melt in the Arctic.

The canal also, unlike the Panama Canal, has no locks at all, making it 【小题3】 (easy) for some of the world’s ships to slip right through and for the canal 【小题4】 (expand ), should the Egyptian government prioritize such a project.

As tough as it may have been to build a canal 【小题5】 this scale, the Suez Canal was far from the first of its kind of area. In fact a canal of this sort was first attempted by Egypt in the 19^th century BC, under the rule of Middle Kingdom pharaoh Senusret II. A canal was reportedly later opened by the time of the Islamic Caliphates but it was reportedly closed in the 8th century AD. That combined with the Red Sea gradually receding away from what are now the Bitter Lakes 【小题6】 (cause) the canal to fade into disuse.

In the following decades, a railway was set up between Alexandria and Suez but this wasn’t good enough for global trade, so guess what they thought of? That’s right, 【小题7】 canal!

Construction broke ground in 1859 and took ten years 【小题8】 a grand total of over 1. 5 million workers throughout the decade.

The area, seeing virtually immediate success, 【小题9】 (declare) in the Constantinople Convention to be an international zone under British protection. This 【小题10】 play a pivotal part in the World Wars, and also contribute to conflict between Britain and Egypt in the Suez Crisis.

The total number of China-Europe cargo (货物)train trips has exceeded 50,000 as a cargo train left the southwestern city of Chengdu on January 29,【小题1】 (office) data showed, a stable contribution to the global supply chain.

The value of goods 【小题2】 (transport) by the cargo service skyrocketed to $ 74.9 billion in 2021. From 2016 to 2021, the China-Europe Railway Express had an increase of 55 percent on average 【小题3】(year), extending to 180 cities in 23 countries in the Europe, and the items have expanded from IT 【小题4】(product) such as mobile phones and notebook computers at the【小题5】 (begin), to more than 50000 items, including auto parts, vehicles, chemicals, electro-mechanicals, food, alcohol, and wood.

The China-Europe cargo train serves 【小题6】 a crucial link for trade and economic cooperation across the Eurasian region. It 【小题7】 (run) smoothly since 2020, as the world is facing the impact of the epidemic (流行病), and the trains also play 【小题8】 important role in fighting the epidemic with the transport of epidemic prevention materials.

A total of 13.62 million pieces of anti-epidemic materials, 【小题9】 (weigh) more than 00,000 tons, have been delivered to Germany, Poland, Belgium and other European countries,【小题10】 has become a “bond of destiny” for countries to join hands in fighting the epidemic.
