There are two kinds of memory: short-term and long-term. Information in long-term memory can be remembered at a later time when it is needed. The information may be kept for days or weeks. However, information in short-term memory is kept for only a few seconds, usually by repeating the information over and over. The following experiment shows how short-term memory has been studied. Henning studied how students who are learning English as a second language remember vocabulary. The subjects in his experiment were 75 college students. They represented all levels of ability in English: beginning, intermediate , and native speaking students. To begin, the subjects listened to a recording of a native speaker reading a paragraph in English. Following the recording, the subjects took a 15-question test to see which words they remembered. Each question had four choices. The subjects had to circle the word they had heard in the recording, Some of the questions had four choices that sound alike. For example, weather, whether, wither, and wetter are four words that sound alike. Some of the questions had four choices that have the same meaning. Method, way, manner, and system would be four words with the same meaning. Finally the subjects took a language proficiency test. Henning found that students with a lower proficiency in English made more of their mistakes on words that sound alike; students with a higher proficiency made more of their mistakes on words that have the same meaning. Henning's results suggest that beginning students hold the sound of words in their short-term memory, and advanced students hold the meaning of words in their short-term memory. The passage centers on _ . A) memory B) two kinds of memory C) short-term memory D) an experiment on student

Q: An Apple employee is in trouble after the prototype of its top-secret iPhone5 was left in a bar. The as yet unreleased prototype was supposedly "misplaced" at Cava22 in San Francisco. Apple's security team was called in after reports that it had been sold over the internet for PS120. However, technology website Cnet.co.uk reports that the San Francisco Police Department said Apple had not reported the item as lost. Cava22 owner Jose Valle has said that neither the SFPD nor Apple have contacted him, although he does remember getting calls about a lost iPhone last month. It follows a very similar incident in April 2010 when a then-unreleased iPhone4 was left in a beer garden of a German bar in California by an Apple engineer. The lost iPhone4 was also sold over the internet to the technology blog, which paid PS3,000. The incident led to Apple strengthening its already stiff security, for it seems difficult to believe that a virtually identical incident would happen for the second time in two years. It is _ that the iPhone prototypes have been lost in the recent years. A) the first time B) the second time C) the third time D) the fourth time

(Question)
Counterfeit ( ) medicines are a widespread problem in developing countries. Like other counterfeits, they look like real products. But counterfeit drugs may contain too little or none of the active ingredients of the real thing. People do not get the medicine they need. And in some cases counterfeits cause death. Twenty children in Bangladesh died last year after being given acetaminophen . The medications contained ingredients that looked, smelled and tasted like the real thing. The medicine was produced by a local drug company that used a dangerous substitute to save money. The problem of counterfeit medicines is especially serious in Africa, Asia and Latin America. The W.H.O. estimates that up to thirty percent of medicines on sale in many of those countries are counterfeit. The problem is less widespread among industrialized countries. The W.H.O. says counterfeits make up less than one percent of the illegal drug market in countries like the United States, Canada, Japan, and New Zealand. But the agency also says as much as fifty percent of the medicine sold on the Internet is counterfeit. Much is being done to fight counterfeit drugs. Several companies are developing ways to make counterfeits easier to identify. And there are existing methods, like a machine that can quickly identify chemicals in pills to confirm if the pills are real. Other ideas include things like special tracking codes for drug packages. People could send a text message with the code and get a message back, which proves that what they bought is listed in a database. Some drug makers and other companies put three-dimensional images called holograms on their products as a security device. We can draw a conclusion from the passage that _ . A) it is very cheap and convenient to buy medicines online. B) medicine companies don't pay much attention to counterfeit drugs. C) more and more people will buy products online. D) we had better not buy medicines online.
