Question

14．MCDONALD'S，one of the world's largest restaurant chains，recently made a big decision．On March 9，the company announced that its chicken suppliers in the US would stop using human antibiotics within two years．
Antibiotics are medicines that attack harmful bacteria（細菌） to help cure illnesses．Many cattle，pig and chicken producers give their livestock（家畜）antibiotics to help them stay healthy．Feeding antibiotics to animals is legal in the US．But the producers feed their livestock not only animal antibiotics，but also those used by humans．Experts say it can lead to public health problems．Overuse of these human antibiotics could cause germs（微生物）to become resistant（抗體）to drugs．When the drugs are used to treat humans，they may no longer be effective．
Many US fast food restaurants already say they serve chicken which are raised without antibiotics，but the decision by McDonald's is important because of its size．The company has over 30，000stores around the world，including 14，000in the US．
In recent years，customers have started to care more about food ingredients（原料）．If they feel certain foods are made with ingredients that are of low quality or don't meet certain levels of quality，they'll choose other higher quality foods．
After seeing customer visits to US stores drop two years in a row，McDonald's says more changes to their food could be on the way．
However，McDonald's won't be applying the new antibiotics policy to its Chinese stores soon．
The company said it's not a double standard but they have to take Chinese food safety standards into consideration．
"The measures will be carried out gradually，based on the actual situation of Chinese agriculture，"McDonald's China said in a statement．

71．According to McDonald's，what will its chicken suppliers in America do within two years？（不多于4個單詞）Stop using human antibiotics．
72．Why do many chicken producers feed their livestock antibiotics？（不多于5個單詞）To help them stay healthy．
73．What is the consequence of overuse of human antibiotics？（不多于9個單詞）It could cause germs to become resistant to drugs．/It can lead to public health problems．
74．For what reason did McDonald's make changes to their food？（不多于6個單詞）Because of the drop in customers．．
