今天我们要学的词是 friction.

friction 的意思是摩擦、不合。 The treatment of migrants in U.S. detention centers has generated friction between the Trump administration and opposition Democrats. 移民在美国的拘留中心所受的待遇引起了特朗普政府与反对派民主党之间的纷争。

A surge in Central American migrants passing through Mexico to seek asylum in the United States has led to both friction and cooperation between the two countries. 大量中美洲移民经由墨西哥前来美国寻求庇护，给美墨两国之间带来摩擦的同时也带来合作。
