system. The Central Pacific Company, starting from California, used
Chinese labor, the Union Pacific employed crews of Irish laborers. 【S6】______
The two groups worked at remarkable speed, each tried to cover a 【S7】______
greater distance than the other. In 1869, they met at a place called
Promontory. Many visitors came there for the great occasion. There
were joyous celebrations all over the country, with parades and the
ringing of church bells honor the great achievement. 【S8】______
The railroad was very important in discouraging westward movement. 【S9】______

troubled一troublesome
解析
易混词误用。troubled作形容词用时,含义为“忧虑的;混乱的”,不能与其后的problems搭配;troublesome意为“令人烦恼的,麻烦的”,能与problems搭配。
