我国人民膳食结构特点及膳食指南是什么?

答案

参考答案:

我国人民现阶段是以植物性食物为主,动物性食物为辅,即粮豆菜为主要食物,肉蛋奶为辅助食物的东亚型膳食模式。这种膳食结构防止了西方国家高热能、高蛋白质、高脂肪、低谷物、低纤维素的膳食结构的弊病,但存在着动物性食品不足,蛋白质质量不高,某些微量元素和维生素不足的缺点。

中国居民膳食指南:食物多样,谷类为主;多吃蔬菜,果薯相辅;奶类豆品,经常应用;适量常吃,鱼禽蛋肉;清淡少盐,少吃肥肉;如若饮酒,应当适量;饮食卫生,防病益寿。

     The requirements for high school graduation have just changed in my community. As a result, all students
must   1   sixty hours of service learning,   2   they will not receive a diploma. Service learning is academic
learning that also helps the community.   3   of service learning include cleaning up a polluted river, working
in a soup kitchen, or tutoring a student.   4   a service experience, students must keep a journal (日志) and
then write a   5   about what they have learned.
     Supporters claim that there are many   6   of service learning. Perhaps most importantly, students are forced
to think   7   their own interests and become   8   of the needs of others. Students are also able to learn real-life
skills that   9   responsibility, problem-solving, and working as part of a team.  10 , students can explore possible
careers  11  service learning.
     For example, if a student wonders what teaching is like, he or she can choose to work in an elementary
school classroom a few afternoons each month.  12  there are many benefits, opponents (反对者)  13  problems
with the new requirement. First, they  14  that the main reason students go to school is to learn core subjects
and skills. Because service learning is time-consuming, students spend  15  time studying the core subjects.
Second, they believe that forcing students to work without  16  goes against the law. By requiring service, the
school takes away an individual's freedom to choose.
     In my view, service learning is a great way to  17  to the community, learn new skills, and explore different
careers.  18 , I don' t believe you should force people to help others-the  19  to help must come from the heart.
I think the best  20  is one that gives students choices: a student should be able to choose sixty hours of
independent study or sixty hours of service. Choice encourages both freedom and responsibility, and as young
adults, we must learn to handle both wisely.
