She leave the book BY the window.
I graduated the university in 2000. BY THEN, I hoped that I would find a good job.
There is OUT OF milk in the refrigerator
(Don't leave BY, BY THEN, OUT OF)
She left the book by the window
I graduated (in physics...) from (name of university) in 2000.
At the time I hoped/I was hoping to find a job (or that I would find....)
The last sentence doesn't make sense.There is out of milk in the refrigerator (???????)
I left the book on the window.
I graduated from the university in 2000. (Both in the simple past tense)
Assuming that you are graduating in 2010 next year, then we have to restate your sentence using a different tense; the future perfect tense.
Example: I will have graduated from the university in April 2010.
By the year 2010, I will have found a job.
compound sentence: I will have graduated from the university in April 2010
and hopefully, I will have found a job by then.
If you graduated in 2000 and hoped in that same year that you would have found a job, yet did not find one, then we can use a different sentence.
When I graduated in 2000, I hoped that I would find a job.
I hope that I contributed in one way or another to the question you posted here. I am trying my best to share the best I know to be able to help fellow members of this site although I am not a native English speaker. In our country, English is a second language and it has always been of interest to me especially when I got the chance to teach some scholars before. Definitely, I have my own share of mistakes and lapses too and I hope that I'm not being pedantic. In fact, I welcome others' opinions and answers because I'm also learning from them.
