Solution:
Este ejercicio está relacionado con el uso de los verbos en el segundo condicional en inglés. El segundo condicional se usa para hablar sobre situaciones hipotéticas y sus resultados probables. Se forma generalmente con la estructura "if + pasado simple, would + verbo en infinitivo".Voy a completar las oraciones proporcionadas con la forma correcta del verbo en el segundo condicional:a. She would buy a house by the beach if she won the lottery.b. If I knew how to play the piano, I would perform at the concert.c. They would travel to Europe if they had more vacation time.d. If he were taller, he would play basketball professionally.e. If it snowed tomorrow, we would make a snowman.f. If I were rich, I would travel around the world.g. She would visit Paris if she had enough money.h. If they won the lottery, they would buy a big house.i. He would come to the party if he didn't have to work.j. If she knew the answer, she would raise her hand.Recuerda que en la cláusula con "if", cuando se trata de un verbo "to be", se usa "were" para todas las personas en el segundo condicional como una forma más formal y correcta, aunque en inglés coloquial a veces se oye "was".
