When all things are considered, young adults of today live more satisfying lives than those of their parents, in my opinion.
这句话当中的“when all things are considered”和“in my opinion“都显得多余。完全可以去掉。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例子，可以替换，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可以去掉,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.
这里的over and over again就可以改为repeatedly,显得更为简洁：
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，上面这句话需要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，不能强调需要表达的重点概念，可以改为下面这句话：
My grandfather couldn’t study engineering because his father needed help on the farm。
2. 避免频繁使用“there be”结构，例如下面的句子：
There were 25 cows on the farm that my grandfather had to milk every day. It was hard work for my grandfather.
可以改为：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.
本句不够简洁的原因是本句的重心应该是“忙碌的家庭-my grandfather’s family”,而使用了被动语态后,仿佛重心变成了cows和hay。下面的表达方式是主动语态,相对来说更简洁一些：
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其实可以用一个动词来表达，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。
Spend time with one or two close friends, or with a large number of friends?
Some people prefer to spend time with one or two close friends. Others choose to spend time with a large number of friends. Compare the advantages of each choice. Which of these two ways of spending time do you prefer? Use specific reasons to support your answer.
Of the two possibilities, I prefer the first, that is, to spend my time with one or two close friends, because I enjoy close friendship with one or two people and the cozy atmosphere of spending time with close friends。 When spending time with a large number of friends, it tends to be difficult to form solid, meaningful friendships with any of the people, since cultivating friendship needs time to communicate。 On the other hand, when spending time with only one or two close friends, it is more likely to get to know these people on a very close level。 I think this closeness is very important in a friendship。 In fact, if I share no closeness with a person, then I do not consider him a friend; I consider him an acquaintance。 Moreover, it is not only closeness but also the cozy atmosphere that makes me prefer spending time with only one or two friends。 In this cozy atmosphere, I always feel there is nothing that I could not or would not tell my friends, as they feel the same。 This means we can trust each other completely。 Although this doesn't at all mean there's no cozy atmosphere or complete trust when spending time with many friends, it is my observation that everyone tends to be more open in private。 This is why I enjoy the intimate friendship。 In addition, spending time with few friends can save much time, since the relationship among a few people is more likely to be simpler。 I'm not proficient at dealing with relationship among people, and often get frustrated communicating with a crowd。 However, when I am spending time with one or two close friends, this doesn't matter at all。 In fact, my close friends, notwithstanding few in number, always tell me I'm their best friend who can truly care about them and handle the relationship smoothly。 I think it is my personality that has me make such a choice。
Profits from the farm were sometimes too small to meet operational expenses, let alone pay for a university degree.
