Open the brackets. Pay attention to the Sequence of Tenses.
At the time I first (meet) Mr. Alien in 1990, he (consider) the possibility of studying foreign languages again. He (forget) everything that he (learn) about Latin and French at school. The languages that he (want) to learn at that time (be) Spanish and Portuguese. He (to be going) to study those languages in the Department of General Education at New York University. Therefore, he (enroll) that school in 1991.After my friend (finish) studying at New York University he (decide) to go to South America for a year. Because he (be, never) there before, he (enjoy) visiting the famous cities of Brazil and Argentina. He (like) San Paulo so much that he (consider) staying there much longer. Before that time he (hope, always) to find a place with an ideal climate. Therefore, San Paulo (seem) to be a real paradise. However, he (spend) all his money and (to be forced) to return.Now my friend Mr. Alien (plan) to visit France next year. He (leave) for Paris on March 15. Mr. Alien (visit) also Germany on the same trip. He (realize) that he must learn French and German before he (go) to Europe. At present he (take) a course in French in preparation for the trip. He (think) that French (be) quite easy. Of course he (be, never) in France before, so he (have) little opportunity to hear French. He (work) very hard at his French every day. He (study) German at New York University next semester. I am sure that he (have) no language problem in the other countries when he (get) there. Many people in those countries (understand) English or French.
