Question

【题目】阅读下面短文，根据短文内容完成句子。

There are many inventions that have caused great changes in the world. Here is a short introduction of the maglev train (磁悬浮). The history of the maglev train started in the beginning of the 1900s. The American Robert Goddard and the French Emile Bachelet came up with the idea of frictionless (无摩擦的) trains. But scientist didn’t succeed in making it at that time.

About 60 years later, the Japanese started their research on maglev transportation. After many years of experiments, the Japanese began to build their first test line. 7 km in 1975, and finished it in 1977. Many test runs started in July, 1977 with a speed of 517 km/h. In 1990, Japan built the Yamanashi Maglev test line. This test line was 42.8 km long and the first running test was held in 1997.

The Germans also started research on the maglev train in the early 1970s. It took them ten years to make the first track(ti)model. In 1993, the longest nonstop test running was 1,674 km. That same year the speed reached 450km/h.

China finished a 30-km-long maglev train line in Shanghai in 2003. This is the first commercial (商业的) maglev train line in the world. Although this project cost over 1 billion dollars, we should feel proud of it.

【1】Robert Goddard and Emile Bachelet ________ the idea of frictionless trains.

【2】In 1975, the Japanese began to build ________ of maglev trains.

【3】The Germans spent ________ in making the first track model.

【4】The Maglev train line in Shanghai is ________ long.

【5】________ made the first commercial maglev train line.

【解析】

本篇文章难度适中，主要讲述磁悬浮列车的发展历史。

【1】根据The American Robert Goddard and the French Emile Bachelet came up with the idea of frictionless (无摩擦的) trains可知，罗伯特戈达德和埃米尔巴切莱特想出了无摩擦火车的主意。come up with想出，且根据句意可知，用一般过去时，故填came up with。

【2】根据After many years of experiments, the Japanese began to build their first test line. 7 km in 1975, and finished it in 1977可知，1975年日本建立了他们的第一个磁悬浮火车测试线，故填their first test line。

【3】根据It took them ten years to make the first track(ti)model可知，德国花费了十年制造第一个履带模式，故填ten/10 years。

【4】根据China finished a 30-km-long maglev train line in Shanghai in 2003可知，上海的磁悬浮线有30千米长。故填30 kilometres/km。

【5】根据China finished a 30-km-long maglev train line in Shanghai in 2003. This is the first commercial (商业的) maglev train line in the world可知，中国建立了第一个商业磁悬浮列车线，故填China。
