Explanation:

To solve this fill - in - the - blank problem, we analyze the context and the given words:

1. First blank (Mr. Yan: Excuse me. How ____ students are in this class?)

We need to ask about the number of students. The phrase "how many" is used to ask about the quantity of countable nouns (students are countable). So we fill in "many".

2. Second blank (Juan: There are twenty - three ____ in the class.)

We are talking about the number of students in the class. So we fill in "students".

3. Third blank (Mr. Yan: ____ many students are here today?)

To ask about the number of students present, we use "How" to form the question "How many...". So we fill in "How".

4. Fourth blank (Mr. Yan: There are ____ students missing!)

We know that there are 23 students in total and 20 are present. To find the number of missing students, we calculate \(23 - 20=3\). So we fill in "three".

Final Answers for each blank:

1. many
2. students
3. How
4. three
