XXIII. Read the text and ask 5 questions on the text. Graduate Education
American universities offer three main categories of graduate degrees. In most
fields of specialization, a master's degree can be earned by one or two academic
years of study beyond the bachelor's degree. A Ph.D. degree (doctor of philosophy)
usually takes at least three years beyond the master's. To earn a Ph. D. in almost
any field, generally a student must pass oral and written examinations in his or
her specialty, produce a long research paper which makes an original contribution
to his or her field of study, and pass reading examinations in one or two foreign
languages.​

Я пока не решил, чем буду заниматься, когда стану взрослым. Выбор призвания ‒ непростое дело, ведь интересных профессий на свете очень много. Возможно, я стану врачом и смогу побороть самые коварные заболевания. Или, пронзив космическое пространство, побываю в других мирах. А может быть, буду изучать таинственные уголки нашей планеты, или займусь выращиванием хлеба. А может, пойду в ученые и найду новый источник энергии, или просто изобрету кухонного робота, который будет вместо мамы готовить обед и мыть посуду. Я всего лишь пятиклассник, и мне трудно сказать, кем я буду. Но я отлично понимаю, что знания, полученные в школе, обязательно мне в будущем, когда я стану трудиться на пользу обществу.

I have not decided what I would do when I'm an adult. The choice of vocation - not an easy task, because the interesting professions in the world very much. Maybe I'll become a doctor and be able to overcome the most insidious disease. Or, piercing space, to visit other worlds. And maybe I will study the mysterious corners of our planet, or loans growing grain. Or maybe go to the scholars and find a new source of energy, or simply invent the kitchen robot that will instead mom cook dinner and wash dishes. I'm just a fifth-grader, and I find it hard to say who I am. But I perfectly understand that the knowledge gained in school, will certainly help me in the future when I'm work for the benefit of society.
