Can somebody help me with this.. to divide the sentences and what kind of sentences they are, and after that to underline the main functional parts in the sentences?

BOB TOLD ME THAT HE HAD BECOME FASCINATED BY BAMBOO WHEN,AS A
STUDENT,HE WENT ON AN AGRICULTURAL STUDY TRIP TO ASIA.WHILE IN VIETNAM
HE HAD STAYED IN A STILT HOUSE AND AFTER CLIMBING THE STAIRS TO THE
FIRST (AND ONLY) FLOOR HE WAS SURPRISED,AND A LITTLE ALARMED,TO
DISCOVER THE FLOOR WAS MADE WITH .I COULD SEE THROUGH THE FLOOR VERY
EASILY,RECALLS BOB AND THE STRIPS WERE QUITE NARROW,NOT WHOLE POLES OF
BAMBOO,I JUST KNEW I WAS GOING TO FALL THROUGH IT.

I have added normal punctuation and capitalization. I have have marked subordinate clauses and pseudo-clauses with brackets [...], verbs and semi-verbs in bold. I have also added "what" in {...} because the sentence seemed incomplete without it.

Bob told me [that he had become fascinated by bamboo [when, as a student, he went on an agricultural study trip to Asia]].
While in Vietnam he had stayed in a stilt house and [after climbing the stairs to the first (and only) floor] he was surprised, and a little alarmed, to discover [{what} the floor was made with].
“I could see through the floor very easily,” recalls Bob, “and the strips were quite narrow, not whole poles of bamboo; I just knew [I was going to fall through it].”

Thank you on the analysis, and would like to ask you for some more help.
I have to divide the compound sentences and mark the sentences concluded
as for example: compound= complex + main clause ,etc...
and beside the subject and the verb the other functional parts as DO, IO, OC, Adjuncts.

Well, I'm afraid I do not understand exactly what you mean by that second sentence. Why not do it yourself, wouldn't you learn more? I am sure someone here would be willing to correct it for you.
