题目内容：

阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。

   I am a vegetarian（素食主义者）．Many people are quick to think of vegetarianism as strange behavior．I treasure our Earth, and since we only have one, we should protect it and the wildlife that lives on it．But that’s only one of the reasons to be a vegetarian．

   Vegetarians may live longer, healthier lives．There is a connection between red meat consumption and various diseases．From an economic standpoint, it requires less land, money and energy to produce foods for a vegetarian diet．While there are many benefits to being a vegetarian, only a handful of those who attempt to adopt this lifestyle succeed．

   The most important quality required to be a vegetarian is firmness since surrounded by the temptation of meat, we tend to give up vegetarianism easily．Creativity is almost as important as commitment．It’s easy to tire of eating nothing but salad． But with a little creativity and some soy products, almost any meal can become vegetarian-friendly．

   Not everyone wants to be vegetarian．Accepting this is part of being a vegetarian with style．Forcing your beliefs on others is disrespectful．Stylish vegetarians should also be able to turn down a meaty dish politely without annoying their hosts．

   Being a successful vegetarian has been easy for me, but it may not be so for others．A common mistake is quitting before your body has adjusted to the change．It can be difficult to keep the lifestyle in the beginning because of temptation．However, it fades over time．Another common mistake is quitting because you’ve been misinformed about the nutritional wisdom of being a vegetarian．That’s why it is vital to be educated． Countless people will tell you that it’s impossible to obtain the nutrients and protein（蛋白质）your body requires without meat, but they are incorrect．People actually need only 44-55 grams of protein a day, and that is easily found in a vegetarian diet．Many meat eaters are consuming three times that amount, which is not beneficial．It leads to diseases．Vegetables can also supply all the vitamins, minerals and nutrients your body needs．However, if you’re still not convinced, you can take a multi-vitamin．
