[填空题]The Americans fought for their independence mainly because of heavy taxes imposed by Great Britain.

参考答案:NG
[解析] 由题干关键词fought for their independence可将答案定位至第一个小标题Taxes in Early America下第二段第一句：Although the American colonists fought for independence from British rule and British taxes，本句并没有说明沉重的赋税是争取独立的原因，而文章其他部分也没有给出独立战争原因的相关信息。
