Question

4．Almost everybody in America will spend a part of his or her life behind a shopping cart（购物手推车）．They will，in a lifetime，push the chrome-plated contraptions  many miles．But few will know-or even think to ask-who it was that invented them．
Sylvan N．Goldman invented the shopping cart in 1937．At that time he was in the supermarket business．Every day he would see shoppers lugging （吃力地携带） groceries around in baskets they had to carry．
One day Goldman suddenly had the idea of putting baskets on wheels．The wheeled baskets would make shopping much easier for his customers，and would help to attract more business．
On June 4，1937，Coldman's first carts were ready for use in his market．He was terribly excited on the morning of that day as customers began arriving．He couldn't wait to see them using his invention．
But Goldman was disappointed．Most shoppers gave the cart a long look，but hardly anybody would give them a try．After a while，Coldman decided to ask customers why they weren't using his carts．"Don't you think this arm is strong enough to carry a shopping basket？"one shopper replied．But Coldman wasn't beaten yet．He knew his carts would be a great success if only he could persuade people to give them a try．To this end，Goldman hired a group of people to push carts around his market and pretend they were shopping!Seeing this，the real customers gradually began copying the phony customers．
As Goldman had hoped，the carts were soon attracting larger and larger numbers of customers to his market．But not only did more people come-those Who came bought more．With larger，easier-to-handle baskets，customers unconsciously bought a greater number of items than before．
Today's shopping carts are five times larger than Goldman's original model．Perhaps that's one reason Americans today spend more than five times as much money on food each year as they did before 1937-before the coming of the shopping cart．

77．What was the purpose of Goldman's invention？It was to make shopping easier and attract more business

解答 76．shoppjng carts 单词理解题．根据上一句Almost everybody in America will spend a part of his or her life behind a shopping cart（购物手推车）．在美国，几乎每个人的生活都和一个购物车有关．此处应该是：他们推着购物车，故答案为：shopping carts．

78．Because few customers used his carts．细节理解题．根据But Goldman was disappointed．Most shoppers gave the carts a long look，but hardly anybody would give them a try．可知他很失望，因为很少有购物者用他的购物车，故答案为：Because few customers used his carts．
79．Because he wanted to promote his shopping carts．细节理解题．根据persuade people to give them a try．可知他是想说服更多的人来用他的购物车．故答案为：Because he wanted to promote his shopping carts．
80．He was a smart businessman．He invented the shopping cart and made it accepted by customers．理解推断题．根据文章内容可知Goldman很聪明．此题答案不唯一，合理即可，故答案为：He was a smart businessman．He invented the shopping cart and made it accepted by customers．
