Exercise 1: Fill in with is, isn't, are, aren't

Let's complete the sentences based on the picture of the dining room:

1. There are four chairs.
2. There is a table.
3. There is a carpet.
4. There is a lamp.
5. There is a painting.
6. There are two windows.
7. There are ten books.

Explanation:
- Use 'is' for singular nouns (a table, a carpet, a lamp, a painting)
- Use 'are' for plural nouns (chairs, windows, books)

Exercise 2: Cross the odd word out

Let's analyze each group and find the word that doesn't belong:

1. wardrobe - bed - sink - chair
   ➡️ sink (it belongs in a bathroom, while others are typical bedroom furniture)

2. fridge - book - table - cooker
   ➡️ book (it's not a kitchen appliance/furniture like the others)

3. sofa - washbasin - toilet - bath
   ➡️ sofa (it belongs in a living room, while others are bathroom items)

4. armchair - carpet - coffee table - garden
   ➡️ garden (it's an outdoor space, while others are indoor furniture items)

5. kitchen - bathroom - bedroom - garage
   ➡️ garage (it's not a living space like the other rooms)

Exercise 5: Fill in with on, under, in, behind, in front of

Looking at the living room picture, let's complete the sentences with the correct prepositions:

1. There are two armchairs in the room.
2. The carpet is under the table.
3. The books are on the table.
4. The table is in front of the sofa.
5. The wardrobe is behind the armchair.
6. The painting is on the wall.

Explanation:
- Use 'in' for enclosed spaces
- Use 'under' for something below something else
- Use 'on' for surfaces
- Use 'in front of' to describe something that is before another object
- Use 'behind' for something that is at the back of another object

Exercise 5: Prepositions of Place

Let's break down the use of prepositions in detail:

1. "There are two armchairs in the room."
   - We use 'in' for enclosed spaces (rooms, buildings, boxes)
   - The armchairs are contained within the room's space

2. "The carpet is under the table."
   - 'Under' indicates position below something
   - The carpet is positioned on the floor beneath the table

3. "The books are on the table."
   - 'On' is used for objects resting on surfaces
   - The books are placed directly on the table's surface

4. "The table is in front of the sofa."
   - 'In front of' indicates position directly before another object
   - The table is positioned in the space between the viewer and the sofa

5. "The wardrobe is behind the armchair."
   - 'Behind' shows position at the back of something
   - The wardrobe is located at the back of the armchair

6. "The painting is on the wall."
   - 'On' is also used for things attached to vertical surfaces
   - The painting is attached to or hanging on the wall

Key Rules for Prepositions of Place:
- 'In' → inside enclosed spaces
- 'Under' → below something
- 'On' → on surfaces (horizontal or vertical)
- 'In front of' → before something
- 'Behind' → at the back of something
