force

by force, by force of

两者含义不同:by force意为“靠武力,强行”,而by force of的意思是“借…之力,依据,由于,通过”。例如:

They occupied by force the whole territory of the country.他们用武力侵占了该国的全部国土。

By sheer force of will, he fought the urge to interrupt the speaker.他完全凭意志力来控制自己想打断演讲人讲话的冲动。

forces, army, military, troops

这组词共同的意思是“军队”“部队”。它们的区别是：

army泛指“武装部队”时,语气比较正式、庄重,它常指“陆军”; military尤指“陆军”,包括全体战斗人员及工作人员,代表军方区别于政府及其他各部门; forces是集合名词,包括国家的各兵种的所有人员及武器装备; troops较通俗,指部队的全体成员,尤指“陆军部队”,有时专指包括各个较低级军衔在内的队伍,以区别于上级指挥官。例如：

They are determined to build up a modern army and navy.他们决心创建一支现代化的陆军和海军。

The military took control of the government in that country.在那个国家,军方控制了政府。

The commander concentrated a powerful force on the left flank.司令员把强大兵力集中在左翼。
