When all things are considered，young adults of today live more satisfying lives than those of their parents，in my opinion.
这句话傍边的“when all things are considered”和“in my opinion“都显得剩余。彻底能够去掉。改为：
Young adults of today live more satisfying lives than their parents.
Due to the fact that our grandparents were under an obligation to help their parents，they did not have the options that young people have at this point in time.
“due to the fact that”就是一个很典型的繁琐的表达方式的比如，能够替换，简化为下面的表达方式：
Because our grandparents were obligated to help their parents，they did not have the options that young people have now.
The farm my grandfather grew up on was large in size.
large 对一个farm来说就是size方面的large，所以in size能够去掉，改为：
The farm my grandfather grew up on was large.
My grandfather grew up on a large farm.
My grandfather has said over and over again that he had to work on his parents’ farm.
这儿的over and over again就能够改为repeatedly，显得更为简练：
My grandfather has said repeatedly that he had to work on his parents’ farm.
The situation that resulted in my grandfather’s not being able to study engineering was that his father needed help on the farm.
从意思上来分析，上面这句话需求表达的重要的概念是“grandfather’s not being able to study”，而在表达这个概念时，原句用的主语是situation，谓语动词是was，不能着重需求表达的重点概念，能够改为下面这句话：
My grandfather couldn’t study engineering because his father needed help on the farm.
2. 防止频频运用“there be”结构，例如下面的语句：
There were 25 cows on the farm that my grandfather had to milk every day. It was hard work for my grandfather.
能够改为：My grandfather worked hard. He had to milk 25 cows on the farm every day.
My grandfather worked hard milking 25 cows daily.
Dairy cows were raised on the farm, which was located100 kilometers from the nearest university and was in an area that was remote.
The dairy farm was located in a remote area，100 kilometers to the nearest university.
In the fall，not only did the cows have to be milked，but also the hay was mowed and stacked by my grandfather’s family.
本句不行简练的原因是本句的重心应该是“繁忙的家庭——my grandfather’s family”，而运用了被动语态后，似乎重心变成了cows和hay。下面的表达方式是自动语态，相对来说更简练一些：
In the fall，my grandfather’s family not only milked the cow but also mowed and stacked the hay.
My grandfather didn’t have time to stand around doing nothing with his school friends.
Stand around doing nothing其实能够用一个动词来表达，即loiter：
My grandfather didn’t have time to loiter with his school friends.
Profits from the farm were not large. Sometimes they were too small to meet the expenses of running a farm. They were not sufficient to pay for a university degree.
Profits from the farm were sometimes too small to meet operational expenses，let alone pay for a university degree.
