   Eating habits change from generation to generation. Before scientists learned about vitamins and other constituents of food, such as proteins and carbohydrates (碳水化合物) , people believed in eating large quantities of food and were not concerned so much about a【C1】______(balance) diet.

   In the year 2020 people’ s eating habits may be just as【C4】______(surprise) but in a very different sort of way. With a world-wide【C5】______(grow) in population, food【C6】______(produce) will become exclusively【C7】______(machine) and scientific. There may well be an end to food as we know it today. Meals, as we know them may become a thing of the past. Food constituents and vitamins may be taken in the form of capsules (胶囊) , tablets and pills. The thought of these highly【C8】______(artificiality) food constituents replacing present day foods may not be very【C9】______(attraction) , but they may be the answer to food【C10】______(short) and world famine.
【C1】
选项
答案balanced
解析 此处需填一个形容词。结合上下文意思可知，人们的饮食习惯慢慢在改变。在科学家还不知道维生素和食物的一些其他成分，比如蛋白质和碳水化合物时，人们总是认为吃得越多越好，而且并不关心平衡的膳食。空格后是一个名词“diet”，因此前面应该有一个形容词来修饰。
