Exercise 1
Step 1
1 of 8
In this exercise, you should put the correct form of the verb in the present progressive.

**estar (to be) + present participle = present progressive**

Here is some useful information to help you master the **present participle**:
– ***-ar*** verbs have the ending ***-ando*** (e.g. camin*ando*)
– ***-er*** and ***-ir*** verbs have the ending ***- iendo*** (e.g. com*iendo*)

Step 2
2 of 8
Here is a table for the verb ***estar*** to help you:

|Singular |Plural |
|–|–|
|Yo **estoy** |Nosotros **estamos** |
|Tú **estás** |Ustedes **están** |
|Él/Ella/Usted **está** | Ellos/Ellas **están**|

Step 3
3 of 8
1. Camila les **está diciendo**….
*(Camila is telling to all the guys what they have to do.)*

*Camila (she)* is third-person singular, so we used the third-person singular form of *estar,* which is *”está.”*

*Decir (to tell/to say)* ends with *-ir*, so we added *-iendo* ending. The stem changed from *e* to *i.*

Step 4
4 of 8
2. Ariadna y Fernanda **se están bañando.**
*(Ariadna and Fernanda are bathing .)*

*Ariadna and Fernanda (they)* is third-person plural, so we used the third-person plural form of *estar,* which is *”están.”*

Note that *bañar**se** (to bathe)* is a reflexive verb, so we used a pronoun appropriate for the third-person singular, which is *”se.”*

Step 5

3. Abel y yo **estamos comprando**…
*(Abel and I are buying train tickets.)*

*Abel and I (we)* is first-person plural, so we used the first-person plural form of *estar,* which is *”estamos.”*

*Comprar(to buy)* ends with *-ar*, so we added *-ando* ending.

Step 6
6 of 8
4. Tú **estás leyendo**…
*(You are reading information about hotels.)*

*Tú (you)* is second-person singular, so we used the second-person singular form of *estar,* which is *”estás.”*

*Leer (to read)* ends with *-er*, so we added *-iendo* ending. The stem changed and *i* turned to *y*.

Step 7
7 of 8
5. Yo **me estoy vistiendo**…
*(I am dressing to go on a vacation.)*

*Yo (I)* is first-person singular, so we used the first-person singular form of *estar,* which is *”estoy.”*

Note that *vestir**se*** is a reflexive verb, so we used a pronoun appropriate for the first-person singular, which is *”me.”*

*Vestir (to dress)* ends with *-ir*, so we added *-iendo* ending. The stem also changed from *e* to *i*.
