it形式宾语的问题
we think it our duty to pay taxes to our government 对还是
we think it is our duty to pay taxes to our government
第一个it是做形式宾语代替 to pay taxes to our government
第二个呢?我怎么觉得第二个对啊
we think it（to pay taxes to our government） is our duty
.
我觉得四楼的靠谱
可是第一个代替的是i代替的是to pay taxes to our government 还是不太懂！
