一个英语句子,大家来看看

首先when引导一个时间状语从句，该从句中，主语是landlords，谓语是pressed，"riding rough shod over tenants"是 动名词短语作landlords的定语~

其次，主句动词是we，有两个并列谓语，即had和were forced to move。而cancelled by them 则是tenancy的定语~

关于逗号，词句中大多数均是起到分隔主谓，以便插入限定语的作用~

不知解释得清楚与否，希望对你有帮助~

In 1904, especially, when landlords, riding rough shod over tenants, pressed for higher rents on the let-out pieces of land, we, unable to meet their demands, had our tenancy cancelled by them and were forced to move house on Newyear's Eve.

1:好复杂的一个句子,这个句子成分该如何划分?

In 1904（状语）, especially, when landlords, riding rough shod over tenants, pressed for higher rents on the let-out pieces of land（when引导一个时间状语从句，修饰in 1904）, we（主语）, unable to meet their demands（状语，表示原因）, had our tenancy cancelled by them and were forced to move house on Newyear's Eve.

2:好多动词,哪个才是谓语动词?
had, were forced.

3:一个句子中不是只能有一个谓语动词吗?这个句子里怎么冒出了这么多个动词出来了?看得我发晕啊

听你这句话，说明你的水平看这样的长句
