Counterfeit medicines are a widespread problem in developing countries. Like other _ , they look like real products. But counterfeit drugs may contain too much, too little or none of the active ingredients of the real thing. People do not get the medicine they need. And in some cases the 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 WHO estimates that up to thirty percent of medicines on sale in many of those countries are counterfeits. The problem is less widespread among industrialized countries. The WHO 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) we had better not buy medicines online B) more and more people will buy products online C) medicine companies don't pay much attention to counterfeit drugs D) it is very cheap and convenient to buy medicines online

Many people say dolphins are very intelligent. They seem to be able think, understand, and learn things quickly. But they are smart like humans or more like cats or dogs? Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are alike in some ways. How? FACT 1: Talk to Me Like humans, every dolphin has its own "name". The name is a special whistle . Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, "talk" to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one "speaks dolphin" yet, but some scientists are trying to learn. FACT 2: Let's Play Dolphins are also social animals. They live in groups called pods, and they often join others from different pods to play games and have fun ---just like people. In fact, playing together is something only intelligent animals do. FACT 3: Fishermen's Helpers Dolphins and humans are similar in another way: both make plans to get something they want. In the sea of southern Brazil, for example, dolphins use a interesting strategy to get food. When fish are near a boat, dolphins signal to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins? Why do they assist the men? The dolphins get to eat some of the fish. The text is most probably taken from a_. A) fiction story B) book review C) science magazine D) personal diary

Q: Two magazines recently listed the best cities to live in. Here are two of the cities listed as "the world's best." SAN JOSE, COSTA RICA The city has comfortable weather all year round (15degC to 26degC ). Housing is not very expensive in San Jose. Also, many of the city's older neighborhoods are very beautiful and have small hotels and cafes . Beautiful mountains are around the city. You can visit them easily from San Jose. So lots of people go sightseeing there every year. But air pollution is a problem in the city center. HONG KONG, CHINA This lively city--once a small fishing village--is today an international business center. It is an interesting mixof East and West, old and new. Modern tall buildings are next to small temples . Popular nightclubs are close to traditional teahouses. Busy people fill the streets at all hours of the day. But outside the city, there are parks for walking or relaxing. Hong Kong is famous for its wonderful native dishes. There's also food from Europe, North America, and other parts of Asia. However, this small city has a large population. Nearly 7 million people live in Hong Kong! That's why housing is often very expensive. Traffic and air pollution are also a problem. From the passage, we can know that _ A) San Jose and Hong Kong are the only two cities of the world's best B) San Jose has more natural sights than Hong Kong does C) the weather in both cities is fine D) Hong Kong is the more popular city of the two

How Many Lies Do the Children Tell You? Mothers who feel their children don' t appreciate them can add another _ to the list: half the time, their children are lying to them. A study designed to expose the truth about lying shows that undergraduates lie to their mothers in 46% of their conversations. Still, mums should feel better than total strangers, who are told lies an astonishing 77 % of the time. Bella Depaulo and a team of psychologists from the University of Virginia, Charlottesville, asked 77 undergraduates to keep a record of all their conversations for a week, and write down whether they lied at any time. DePaulo named lying broadly, as "when you intentionally try to mislead someone", so she would catch the smallest of lies. The students told an average of two lies a day. They said they had been studying when they had been out drinking. One told his parents that a textbook cost $50 rather than $20 so that they would send him extra money. Female students constantly told their plain-looking roommates that they were pretty. "They are everyday lies," says DePaulo. DePaulo and her colleagues conclude that people tend to tell fewer lies to those they feel closest to. College students lied to their best friends 28% of the time but lied to acquaintances 48% of the time. In close relationships, people were more likely to tell "kind-hearted" lies, designed to protect feelings, rather than self-serving lies. Romantic partners lie somewhere between close friends and acquaintances. Students lied to romantic partners about a third of the time. DePaulo thinks that unmarried lovers can expect less honesty than best friends because of the insecurity that comes with romance. Mothers can take heart from one other finding. They may have been lied to, but at least their children talked to them. The students were recorded telling few lies to their fathers because they had little interaction with them. What is the purpose of this article? A) To present a fact. B) To argue an idea. C) To tell a story. D) To explain a theory.
