In Spanish, there is no need to change the word order. Since the problem asks for the change of this order we will use simple steps to do this. Thus, we will form Spanish questions from declarative sentences.
1) Begin with a typical declarative sentence: We start normal sentences with the subject and next follows to the verb.
2) Exchange the order of the subject and the verb: In English, when you say this is... in the simple form you say is this...? in the question form. In fact, the same happens in Spanish. So you, for example, change ésta es... to ¿es ésta...? The same process also works for other sentences that don’t fit the this is... standard like la niña es bonita to ¿es bonita la niña?
3) Do not worry about do: In English, questions often include the verb do, but the word do is understood as part of the verb in Spanish.
Therefore, the change is as follows:
1. ¿Prepara la prueba la Profesora Cruz?
Does the teacher Cruz prepare the test?
2. ¿Necesitamos estudiar Sandra y yo?
Do Sandra and I need to study?
3. ¿Practican los chicos el vocabulario?
Do the boys practice the vocabulary?
4. ¿Termina Jaime la tarea?
Does Jaime finish the homework?
5. ¿Trabajas tú en la biblioteca?
Do you work in the library?
