俗话说:“便宜没好货,好货不便宜”,可是在实际生活中,人们为什么总是能够选购到“价廉物美”的商品?

答案

(1)商品是使用价值和价值的统一体。实际生活中,人们选购商品既要考虑其价格,也要考虑其使用价值,追求高的性价比。(2)不同商品生产者生产同种商品耗费的个别劳动时间不尽相同;个别劳动时间低于社会必要劳动时间在竞争中就处于有利地位,某商品生产者为扩大市场份额(占有率),有可能率先降价,此时,人们选购商品时可能找到使用价值和价格的理想的结合点,选购既“物美”又“价廉”的商品(3)当生产技术进步,生产工艺改进,社会性劳动者生产率提高,单位商品价值量下降,同时,产品质量提高,人们也有可能选购到价廉物美的商品。(4)供求影响价格。供不应求,价格上涨,供过于求,价格下跌。当高质量的商品处于供过于求的买方市场时,消费者也能买到“价廉物美”的商品

阅读下面短文,并根据短文后的要求答题。

      The relationship between students and teachers is less formal in the U.S. than in many other countries,

especially at college. (1)当老师走进教室时,学生不必起立。Students are encouraged to ask

questions during class, to go to the teacher’s office for help after class, and to phone if they can’t go to

school and need help with their lessons. (2)Most teachers allow students to enter class late or leave early,

if necessary.

     (3)However, students are still asked to be polite to their teacher and classmates and to be quiet during

a test. When students want to ask questions, they usually put up a hand and wait. When the teacher or a

student is speaking to the class, it’s rude to talk to another classmate, even in a low voice. When a test is

being given, talking to a classmate is not only rude but also wrong. In the eyes of most American teachers,

students who are talking to each other during a test are cheating.
