英语高手快来..急！！！！！！

1。By the end of the week, I 【had 改成 will have】 almost earned a hundred dollars in tips.
这里谓语要用将来完成时 will have earned
到这个周末，光光是小费我就差不多会赚到100美金。

By the end of the week没错，不用改。就是指这一周结束时。

2。 fragment run-on misplace modifier 不知道楼主写什么

3。Charlotte loved the movie Gone with the Wind, but Lyde hated it. His chief objection 【being 改成 was】that it lasted four hours.
Charlotte喜欢电影《飘》但是Lyde讨厌它。他的主要理由是那部电影长达4小时。
原句第二句缺少谓语或系动词，要把being改成was才形成完整句子。

By the end of the week, I had almost earned a hundered dollars in tips.

时态和谓语一致, 可以做此处理:
By the end of this week, I will have earned a hundered dollars in tips.
或者By the end of last week, I have almost earned a hundered dollars in tips.
week 前接定贯词, 有些不知所云, 在习惯表达里也是不对的.

Charlotte loved the movie Gone with the Wind, but Lyde hated it. His chief objection being that it lasted four hours.
应改为Charlotte loved the movie Gone with the Wind, but Lyde hated it. His chief objection was that it lasted four hours.

modifier 指程度副词如very 第一局基本上没有错误

Charlotte loved the movie "Gone with the Wind", but Lyde hated it. The main reason is that it lasted four hours. 会比较通顺。
