gozentyuu ni kyouzai wo insatusite, gogo ni gakusei ni kubarimasu.

Because the sentence links two actions in sequence:

• 教材を印刷して
• 学生に配ります

The て-form connects actions and often means and then or after doing that. So the sentence means:

• I print the teaching materials in the morning, and then distribute them to the students in the afternoon.

Only the final verb, 配ります, carries the main tense/politeness marking for the whole sentence.

Not exactly.

• 午前 = A.M., or the morning as a time period before noon
• 午前中 = during the morning, throughout the morning, or sometime in the morning

The 中 adds the idea of within that period.

So:

• 午前に = in the morning / in the A.M.
• 午前中に = sometime during the morning

In this sentence, 午前中に sounds natural because the printing happens during that morning period.

Here, に marks the time when something happens.

• 午前中に = in the morning
• 午後に = in the afternoon

Japanese often uses に with specific times or time periods to show when an action takes place.

In this sentence:

• 午前中に tells you when the printing happens
• 午後に tells you when the distributing happens

Because 教材 is the direct object of 印刷する.

• 教材を印刷する = to print teaching materials

The particle を marks the thing directly affected by the action. Here, the thing being printed is 教材.

Because 配る means to distribute/give out something to someone, and the person receiving it is marked with に.

Pattern:

• A を B に 配る
• distribute A to B

So here:

• 教材 is the thing being distributed
• 学生に marks the recipients

Even though 教材 is omitted in the second half, it is understood:

• 教材を印刷して、午後に学生に配ります。
• Print the materials in the morning, and distribute them to the students in the afternoon.

A fuller version could be:

• 午前中に教材を印刷して、午後に学生に教材を配ります。

But repeating 教材を is often unnecessary.

Yes, the subject is omitted, which is very common in Japanese.

The sentence does not explicitly say I, we, or the teacher. Japanese often leaves out information that is obvious from context.

Depending on the situation, it could mean:

• I print the materials in the morning and distribute them to the students in the afternoon.
• We print the materials in the morning and distribute them to the students in the afternoon.

The subject is understood from the context rather than stated.

Not quite.

• 教材 = teaching materials / instructional materials
• 教科書 = textbook

教材 is broader. It can include:

• handouts
• worksheets
• printed lesson materials
• practice sheets
• other classroom resources

So in this sentence, 教材 probably means materials prepared for students, not necessarily a textbook.

Often, yes.

配る means to distribute, to hand out, or to give out. In a classroom context, 学生に配ります usually means something like:

• hand them out to the students
• distribute them to the students

So this is a very natural verb for giving printed materials to a group.

Because Japanese often omits repeated information when it is already clear.

The sentence literally says:

• In the morning, print the materials, and in the afternoon, distribute them to the students.

Even though them is not stated separately in Japanese, it is understood from 教材を earlier in the sentence.

So this is a natural omission, not a mistake.

Yes, but the nuance changes a little.

Current sentence:

• 教材を印刷して、午後に学生に配ります。

This smoothly connects the two actions as part of one plan or routine.

If you used something like それから, it would sound more explicitly like:

• print the materials, and after that, distribute them

That is possible, but the て-form is simpler and more natural here.

午後に is the more natural choice here.

• 午後に = in the afternoon
• 午後中に would mean something like during the whole afternoon or sometime within the afternoon, but it is less common and often unnecessary here

Since the sentence just needs to say when the distribution happens, 午後に works well.

By contrast, 午前中に is especially common and natural when talking about doing something sometime during the morning.

配ります is the polite non-past form of 配る.

This style is called ます-form and is commonly used in:

• classrooms
• workplaces
• neutral polite conversation
• written schedules or plans

The plain form would be:

• 配る

So the sentence is polite but not overly formal.

Yes, that is the natural interpretation.

Because of:

• the て-form connection
• the time expressions 午前中に and 午後に

the sentence implies this sequence:

1. print the materials during the morning
2. distribute them in the afternoon

So the first action happens before the second one.
