In this exercise you have to complete the sentences by using the contraction of the definite articles **le/les** with the preposition **de**.

Note: de + (le/les) = du/des.
There’s no contraction with **de** plus **la** or **l’**: **de la**, **de l’**.

In this case we have: **fille rousse**, singular feminine noun that has the definite article **la**, therefore: la soeur **de la** fille rousse.

de la

**Garçon** is singular masculine noun with the definite article **le**, thus the contracted form between **de** and **le** is **du**: **le père du garçon** grand et blond.

du

In this case we have **copine**, feminine singular noun: **la copine**. As there’s no contraction with the feminine definite article **la**, the correct form is: **de la** copine de ta soeur.

de la

In this case we have the noun: **amie** starting with the vowel. The definite article is therefore **l’**, **l’amie**. As we don’t contract the elided definite article **l’**, the correct form is: **de l’** amie de Habib.

de l’

**Professeur** is masculine singular noun, so **le professeur**, accordingly: **de** + **le** = **du professeur**.

du

In this case we have the masculine plural noun **frères**, the correct definite article is **les** and the contracted form between **de** and **les** is **des**.

Note: the definite article **les** is the same for both genders in the plural: **les frères** BUT **les soeurs**, as well.
