Russian alphabet in print and cursive handwriting styles.

The image you provided is a chart comparing the print (block) and cursive forms of the Russian alphabet. The task appears to be about practicing or identifying the cursive forms of the Russian letters.

Explanation of the Chart:

1. Columns:
- The chart is divided into three main columns, each containing pairs of print and cursive letters.
- Each pair shows:
- The print (block) form of the letter on the left.
- The cursive form of the same letter on the right.

2. Rows:
- Each row corresponds to one letter of the Russian alphabet.
- The rows are organized in the standard order of the Russian alphabet.

3. Purpose:
- This chart is likely used for educational purposes, such as teaching students how to write Russian letters in both print and cursive styles.
- It helps learners recognize and practice the cursive forms of letters they may already know in print.

Solution Approach:

Since the task involves solving or explaining the problem, let’s break it down:

#### Step 1: Understand the Structure
- The chart lists all 33 letters of the Russian alphabet (including Ё).
- For each letter, the print form is given first, followed by its corresponding cursive form.

#### Step 2: Identify Missing Information
- In some cells, the cursive form is missing or needs to be filled in. For example:
- Ъ (Hard sign): The cursive form is not provided.
- Ь (Soft sign): The cursive form is not provided.
- Ы (Ы): The cursive form is not provided.

#### Step 3: Provide the Missing Cursive Forms
Here are the missing cursive forms for the letters mentioned above:
- Ъ (Hard sign): The cursive form is typically written as a small "ъ" with a slight flourish.
- Ь (Soft sign): The cursive form is typically written as a small "ь" with a slight flourish.
- Ы (Ы): The cursive form resembles a combination of "и" and "ь".

#### Step 4: Fill in the Chart
Using the information above, the missing cursive forms can be added to the chart. Here’s how it would look:

| Print | Cursive |
|-------|---------|
| Ъ | ъ |
| Ь | ь |
| Ы | ы |

Final Answer:

The missing cursive forms are:
- Ъ: ъ
- Ь: ь
- Ы: ы

Thus, the completed chart would include these forms in their respective cells.

Final Answer:
\boxed{ъ, ь, ы}
