6、he same time that the american waistline began to expand.health experts have tried to get many restaurants to serve smaller portions. now, apparently，some customers are calling for this too. the restaurant industry trade magazine qsr reported last month that 57 percent of more than 4,000 people surv

7、eyed believe restaurants serve portions that are too large; 23 percent had no opinion; 20 percent disagreed. but a closer look at the survey indicates that many americans who cant afford fine dining still prefer large portions. seventy percent of those earning at least $150,000 per year prefer small

8、er portions; but only 45 percent of those earning less than $25,000 want smaller.its not that working class americans dont want to eat healthy. its just that，after long hours at low-paying jobs，getting less on their plate hardly seems like a good deal. they live from paycheck to paycheck ，happy to s

15、这样的话，吃光你盘子里的东西，做清盘俱乐部的成员。这些话表达的意思就是不要浪费粮食。因此 c 是正确的答案。2. a 本题问的是:美国饭馆为什么饭菜给得多？第二段相关的话是这么说的：美国人在传统上把东西值不值是跟数量联系在一起，因此大多数的饭馆给的量大。这些饭馆乐于让顾客们抱怨饭菜给得太多而不乐于让他们抱怨饭菜给得太少。所以 a 是正确的答案。3. d 本题问的是：20 世纪 70 年代发生了什么？文章第三段是这样说的：一位宾州大学营养教授，barbara rolls ，告诉今日美国20 世纪 70 年代饭馆给的饭菜的量开始增加，与此同时，美国人的腰围也开始增大。所以 d 是对的。4. a 本

16、题问的是：调查报告说明了什么？选项 b、c和 d 所说的数字不对。因此唯有 a 是正确的。a说的是：许多美国穷人希望量大。这个信息可以在第四段中找到。相关的句子是这么说的：许多吃不起精美正餐的美国人仍然要量大。5. c 本题问的是:下面的哪种说法不带合美国工人的实际情况？ c 说的是：他们不想做吃得健康的人。这个说法是不对的。最后一段的第一句话是这么说的：美国工人不是不想做吃得健康的人。因此 c 正确。第十九篇 prolonging human lifeprolonging human life has increased the size of the human population. m
