Untitled i visited a friend of my parents' this evening .my impression of him was not very good before .years ago ,i saw some bad behaviors of his. i thought he was not responsible to his family then ,and maybe he thought i was too young to know that .this evening ,i saw his other side ,the side which shows his eloquence and humorous to people around him .he is really capable of something .at least he is good at taking .we always have two sides ,one is bright ,the other is dark .

the simple past or the past perfect ? i got ready at the time you told me to .can i say "i had got ready at the time you told me to "in place of it ?

the past perfect tense i had not understood the problem until he explained it .why not "i didn't understand the problem until he had explained it "?is it because "i" had tried to "understand " him but "i " had failed before he explained it ,so the action "understand "took place before the action "explain "?

neither of or either of ? he could not answer neither of /either of the questions i asked .i think "either of "is correct ,but the key is "neither of ".i'm puzzled ~

The past continuous or the simple past? There is a sentence in my book:She droppd the tray when Ｉspoke to her. I cannot understand why "spoke"is used but not "was speaking".

Miserable The results of the exams have been announced.I hope it doesn't bother you because every composition I have written refers to the exams.But this is the real life of Chinese teenager.That's it. The results are not as good as I ever expected.I may not be able to enter the school which I would like to enter.It seems that the first step to my future has been ruined. I have just taken a bus around the city with my friend.We took the bus from the starting station to the final one.We talked about our results ,the school we may enter,etc.After talking ,the sad feelings faded away for the time being. But now,I'm still feeling upset.I really have no ideas about it.
