The worksheet focuses on forming plural nouns. Let's break it down step by step:

#### Part 1: Write the plural forms of these nouns

We are given a list of singular nouns and need to write their plural forms. The rules for forming plurals are provided in the table at the top of the worksheet.

Rules Recap:
1. Regular nouns (ending in s, ss, ch, sh, x, z, o): Add -s.
2. Nouns ending in a consonant + y: Change y to i and add -es.
3. Nouns ending in f or fe: Change f/fe to v and add -es.

Now, let’s solve each noun:

| Singular | Plural |
|----------|--------|
| box | boxes | (regular noun, ends in "x" → add -es) |
| library | libraries | (regular noun, ends in "y" but preceded by a vowel → add -s) |
| tax | taxes | (regular noun, ends in "x" → add -es) |
| class | classes | (regular noun, ends in "s" → add -es) |
| patch | patches | (regular noun, ends in "ch" → add -es) |
| echo | echoes | (regular noun, ends in "o" → add -es) |
| loaf | loaves | (noun ending in "f" → change "f" to "v" and add -es) |
| bus | buses | (regular noun, ends in "s" → add -es) |
| worry | worries | (regular noun, ends in "y" but preceded by a consonant → change "y" to "i" and add -es) |
| dictionary | dictionaries | (regular noun, ends in "y" but preceded by a vowel → add -s) |
| pile | piles | (regular noun, ends in "e" → add -s) |
