請依下文回答第 46 題至 50 題
An estimated US$2.8 billion in expired medication and unfinished prescription drugs is thrown away each year inthe US. While throwing drugs in the trash or down the drain may seem harmless, this is far from the truth. When drugsare flushed down the toilet, they can make their way into water sources. Many water treatment facilities are not equippedto filter out this type of contamination. This can damage both marine and human life. In addition, leftover medicationcan end up in the wrong hands. Between the years 2000 and 2015, poison control centers in the US receivedapproximately 30 calls each day about children who had accidentally consumed medication that had been improperlystored or disposed of.
The US Drug Enforcement Administration (DEA) has taken steps to combat mishandled medicine. In 2010, itlaunched “National Drug Take-Back Day.” This allows people to bring their unwanted pills to specific sites around theUS. The main drawback is that these sites are only open once every two years. Fortunately, people may mail unconsumeddrugs to the DEA at any time. Drugs that have been returned are then burned.
There is, however, an alternative; rather than destroying the medicine, people can donate it. Certain pharmacies inthe US will inspect the medicine to make sure it hasn’t been
tampered with
and is still safe to use. Then they will giveit to patients who are unable to afford it. One program, “SafeNetRx,” has redistributed nearly US$54 million worth ofmedications and medical supplies. These programs are working hard to counter the harm caused by unused drugs. Wecan help reduce the potential risks associated with medications even further if we store them in individual containers,keep them locked up, and dispose of them in an appropriate manner.
【題組】
50 What does the author say about “SafeNetRx”? (A) It is the only program in the US to reduce the risk of unused drugs. (B) Numerous patients have received medical supplies through the program. (C) People learn how to store medicine properly through their service. (D) The program’s pharmacists will destroy unused drugs donated by people.
【題組】
49 Which of the following is closest in meaning to “tampered with”? (A) Touched. (B) Paid. (C) Examined. (D) Discarded.
【題組】
48 Which of the following is true about the actions taken by the US DEA? (A) People are forbidden to bring their unwanted pills to the DEA. (B) The DEA held the first “National Drug Take-Back Day” in 2015. (C) Unconsumed drugs can be sent to the DEA at any moment. (D) The drugs that the DEA receives will be recycled.
