A new U．S．government report says more than two million Americans fall ill each year with drug—resistant bacterial infections(感染)，and 23，000 of them are dying as a result．The head of the United States Centers for Disease Control and Prevention[CDC]said that the number probably will grow．Officials warn that steps must be taken now to preserve the effectiveness of antibiotic(抗生素)drugs．
Without urgent action to stop that trend，warned Tom Frieden whose agency wrote the report，the miracle drugs to fight them won’t be available in the future．
“If we are not careful，the medicine chest will be empty when we go there to look for a lifesaving antibiotic for someone with a deadly infection．But if we act now，we can preserve these medications while we continue to work on development of new medicines．”
The report names a drug—resistant abuse of gonorrhea(淋病)，which causes about one quarter of a million hospitalizations in the United States annually．Of the number at least 1 4，000 result in death．
Drug resistance develops through the overuse and inappropriate use of anti—bacterial agents．These can be：doctors prescribing(开药) them to patients who have viral infections that are not affected by medicine meant to fight bacteria；patients not taking all of their medicine as prescribed，so the bacteria making them sick are only weakened，not killed；antibiotic use in healthy farm animals to prevent illness and promote growth．Antibiotic remainders left in meat and animal products can then lead to drug resistance in humans．
To limit the spread of resistant infections，experts recommend wider use of routine immunizations(预防)，as well as hand—washing in hospitals and other health care facilities．Also， the report urges hand—washing by food handlers．?
Michael Bell，deputy director of the Division of Healthcare Quality Promotion at CDC，said Patients also can play a role in preserving the effectiveness of antibiotics by asking health care providers a few simple questions．
【小题1】What’s the best title of the passage?A．Drug Resistance Developing Quickly in the USB．Drug—Resistant Bacterial Infections Growing in the USC．Actions for Preserving Anti-Bacterial Medications in the USD．Preventions of Drug-resistant Bacterial Infections in the US【小题2】According to Frieden，we must take measures without delay to preserve effectiveness of antibiotics，or .A．we will have to develop better medicines in place of antibioticsB．there may be no effective anti-bacterial drugs for use in the futureC．we can’t find other medicines to cure serious illnesses in the futureD．more and more Americans will suffer from bacterial infections each year【小题3】Of those patients admitted to the hospital because of a drug-resistant abuse of gonorrhea annually，deaths add up to .A．at least 5.6％B．about 25％C．about 1.4％D．at least 2.5％【小题4】One of the approaches through which drug resistance develops is that .A．people eat the meat with Antibiotic remainder in animalsB．doctors prescribe less antibiotics than needed for patientsC．doctors prescribe much more antibiotic than needed for patientsD．patients don’t take their ant-bacterial agents that doctors prescribeC

(答案→)C 解析：本文介绍了人类滥用抗生素以及食用有抗生素产生耐药性的肉制品会使人体内产生抗药性，最终导致死亡的严重后果。从现在起人们应采用有效的行动防止这一后果的发生。【小题1】推理题：阅读文章内容可知全文在讲述人体内产生抗生素耐药性的严重后果，我们应采取有效行动防止这一后果的发生。故选C。【小题2】细节题：根据第二段中“the miracle drugs to fight them won’t be available in the future．”在将来是不会有奇效的药物来对抗他们的。故选B。【小题3】推理题：根据第四段内容可知250000人产生淋病的抗药性，会有14000导致死亡，计算后可知几率为5.6%。故选A。【小题4】推理题：根据第五段内容可知人们产生抗药性有两种途径，一种是滥用药物，本是病毒感染却使用抗生素，效果不明显，却产生抗药性；一种是食用残留有抗药性的肉制品。故选A。
