Choose which "to be" verb to use: ser or estar. / Elige ser o estar. 1. Elena _____ preocupada hoy. Tiene un examen. 2. Mis estudiantes _____ muy inteligentes.
1. está (3rd person singular conjugation of estar). Preocupada is an emotion, something temporary, which is one of the situations in which we use estar. 2. son (3rd person plural conjugation of ser.) Inteligente is a lasting characteristic, so we use the more permanent ser.
A. Diagram this conditional statement: If I see a chihuahua, I will frown. B. Which of the following is also true? 1. Frown -> chihuahua 2. No frown -> no chihuahua 3. No chihuahua -> no frown
A. Chihuahua -> frown B. The answer is 2, the contrapositive. It can't be 1 because I won't necessarily see a chihuahua every time I frown. It can't be 3 because I could be frowning for other reasons, even if I didn't see a chihuahua. This always applies to conditional statements! The contrapositive is the only thing we can infer from a conditional statement.
In which situation do we NOT use the second conditional? A. An event unlikely to happen in the future B. An event that might happen in the future C. An impossible event in the present
B-- this is a use of the first conditional. A and C are the two times we use the second conditional. A and B are subtly different. Take these classic examples: For A we could say "If I won the lottery, I would..." because it's unlikely to happen. For B we could say "If it rains, I will..." because it might happen. It's quite possible.
