Jump to: Rules · Compare · Examples · Self-checks · Answers
9.1 Myself, yourself and themselves
| Learn | Simple English |
|---|---|
| Rule | Use a reflexive pronoun when the action comes back to the same person. The subject and object are the same. |
| Pattern | I → myself. You → yourself/yourselves. He → himself. She → herself. It → itself. We → ourselves. They → themselves. |
| Example | I introduced myself. She introduced me. |
| Why | I did the introducing, and I was the person introduced. In the second sentence, she introduces a different person: me. |
9.2 One thing or several things
| Learn | Simple English |
|---|---|
| Rule | A singular noun names one thing. A plural noun names more than one. Many plurals add -s, but some change. |
| Pattern | One chair → chairs. One box → boxes. One child → children. |
| Example | One person is here. Three people are here. |
| Why | Use a, the or my before many singular countable nouns: a chair, the chair, my chair. |
9.3 Ideas and feelings
| Learn | Simple English |
|---|---|
| Rule | Abstract nouns name ideas, feelings or qualities. Examples include kindness, confidence and freedom. Some can be counted; others cannot. |
| Pattern | An idea → two ideas. Some confidence, not two confidences in this meaning. |
| Example | Her kindness helped me. I have two ideas. |
| Why | Abstract does not mean uncountable. You can count ideas even though you cannot touch them. |



9.4 Compare the patterns side by side
| Question | Word family | Example |
|---|---|---|
| Who does it to the same person? | Reflexive | She introduced herself. |
| How many items? | Singular / plural | One chair; three chairs. |
| What idea or quality? | Abstract noun | Confidence helps us speak. |

💡 The people doing the introducing are also the people introduced. Use themselves with they.
2. B — children
💡 The plural of child is children, not childs.
3. A — kindness
💡 Kindness is a quality. Chair names a physical object. Kindness is an abstract noun.
4. B — I did it alone or without help.
💡 By myself usually means alone or without help.
5. B — The furniture is new.
💡 Furniture is normally uncountable. Do not add -s; use is in this sentence.

Myself refers back to I.
One child becomes two children.
Kindness is a quality; ideas can be counted.
