That was exactly what happened several days ago, causing me great embarrassment.I was waiting for my train home at the station when a boy 17 at my side. His beautifully-curved face, his fashionable clothing and everything else about him, was so 18 that I just couldn’t help gazing (注视) at him.

However, once again when our eyes met, I could hear my heart 22 wildly, with an inner voice yelling, “Oh, my goodness, he is driving me 23 !” Shortly, I lowered my head to 24 his eyes, but my thoroughly red face had revealed (泄露) 25 .To my pleasant surprise, my 26 came true this time, as the handsome guy was drawing 27 ! “Oh, please! Don’t 28 . Look at me. I am so sweaty and sloppy (多情的). Please don’t 29 my telephone number. You know I will give it to you without 30 , and that is so unladylike!” I was still struggling and trembling when he 31 right in front of me. “Excuse me...” he said with a slight hesitation. His voice was so nice, but I wish I had not 32 it, for in the end, he said: “I am sorry, but could you please give me my 33 back? Yours is over there.” Oh, my God!

在每小题列出的四个选项中,只有一项是最符合题目要求的。

1.假设某国2011年货币流通次数为5次,2012年因受各种因素的影响,该国待售商品总量增加30%,商品平均价格水平则下降20%,而流通中的货币量增加30%。

在其他条件不变的情况下,该国2012年的货币流通次数为A.3次B.4次C.5次D.6次2.收入是消费的基础和前提。

右图表示居民收入和消费的关系(纵轴为收入,横轴为消费,S1为变动前曲线,S2为变动后曲线)。

在不考虑其它因素条件下,以下变量会导致S1向S2方向平行移动的是①居民消费价格指数(CPI)下降,实际工资上升②社会劳动生产率提高③基尼系数(居民收入差距)扩大,超过0.4的国际警戒线④建立健全覆盖全社会的社会保障体系A.①②③B.①③④C.②③④D.①②④3.随着科技的进步、互联网的盛行,网络商店遍地开花,网上购物悄然改变着人们的生活方式,网络团购正成为新的消费热点。

对此认识正确的是①生产决定消费的方式并为消费创造动力,消费引导生产,是生产的目的和动力②价格影响消费,因为网购减少了流通环节,降低了商品成本③网络团购是从众心理消费和求实心理消费④网络购物标志电子货币时代的到来,货币职能发生了本质变化A.①②B.②③C.①③D.③④4.凯恩斯认为,有效需求不足主要是由三个基本心理规律决定的。
