the usage of "when"

I am very sad,I haven't mastered that a simple word "when"!

I did some exercises in NCE,I have made so many errores on this word!

e.g.

I was reading when daughter taked a card for me.

When I was reading,daughter taked a card for me.

Which sentence is correct?

present,present perfect,P perfect continuous tense

I found I haven't mastered these three tense completely by doing some exercises in NCE.

present:

He drinks three glass of water a day.

present perfect:

He has drinked three glass of water this morning.(e.g. from 7:00 to 11:00 in this morning)

but this usage isn't common.

He has seen that movie three times.

see (http://www.englishpage.com/verbpage/presentperfect.html):

Sometimes we want to limit the time we are looking in for an experience. Expressions such as "in the last week," "in the last year," "this week," "this month," "so far" and "up to now" can be used to narrow the time we are looking in for an experience.

EXAMPLES:

Have you been to Mexico in the last year.

I have seen that movie six times in the last month.

They have had three tests in the last week.

She graduated from university less three years ago. She has worked for three different companies so far.

This week my car has broken down three times.

NOTICE

"Last year" and "in the last year" are very different in meaning. "Last year" means the year before now. "In the last year" means from 365 days ago until now.

EXAMPLES:

I went to Mexico last year.

(I went to Mexico in 1998.)

I have been to Mexico in the last year.

(I have been to Mexico at least once at some point between 365 days ago and now. We do not know exactly when.)

present perfect continuous:

He has been drinking a lot of water this morning.(He is still drinking the water.) (not correct)

He has been drinking a lot of water since this morning.(He is still drinking the water.) (not correct)

CE forum-Tanslation

1:Translation really tests our reading and comprehension ability;

2:Emphasis:attributive clause,adverbial clause,passive clause,指代pronoun,special statement matrix(inverted statement matrix,there be,虚拟mood);

3:we should give only one answer for every translation question,or,if you give multiple answers and there is some wrong in one of the answers,you will fail on this question;

4:we should learn to unpack some long and difficult sentences.
