哪一個段落沒有主題句？ 我覺得是第一個，對嗎？ 要怎麼替這個段落寫出主題句呢？

2 Despite different home cultures and countries, international students' main overall motivation is the desire get out on their own, to carve out a new direction in their lives. "Foreign students" do not casually abandon the comforts of family and cultural ties; they have done their homework on Canadian schools. All their preparation, though, cannot prepare them for the loneliness and ongoing difficul- ties they face, from cold winters to financial issues related to the higher tuition fees they must pay. Some students, though, emigrate to escape those same tight- knit families and bonds that others find so painful to leave behind. A Macleans "On Campus" report notes that family expectations may be opposed to students' visions for themselves and lead them to reject accepted values and career paths in their hometowns and countries. Csilla, a web-design student at Waterloo admits, "I was always supposed to enter my family's restaurant business in Budapest, but I felt suf- focated even working part-time as a server. Web design is my passion, and I wanted 12: CAUSE OR EFFECT [- a completely fresh start, something that is completely my own ("International Stu- dents"). Finding independent paths to their own dreams is the key here, whether students choose those paths as a result of personal ideals or as a reaction to pre-set future plans.

第 43 至 46 題為題組 20 Istroshod as to orius orbini.com When comparing different regional versions of Buddhism, Tibetan Buddhism strikes many bas particularly unique. This is in part due to the fact that Buddhists in Tibet practice a form be of Buddhism called Vajrayana, or "the way of the diamond," which differs significantly from Theravada (the form practiced primarily in Southeast Asia) and Mahayana (the form practiced primarily in China and East Asia). Another reason is that the Tibetan form has been heavily influenced by Bon, the indigenous folk religion of Tibet. Een twis John et 誰有物無論有無 Studie Originally, Bon was an animistic religion, meaning that adherents, called Bonpo, believed all things, living or not, possessed a soul. At the time, they didn't consider Bon a religion but a set of traditions. The priest himself was called a Bon, and his role was to conduct rituals, such bantas sacrificing animals, to assist humans to make their journey to the afterlife upon dying.
