Question: Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Swimming in the water of Hawaii's Big Island is a fun experience. But it can be more exciting if there are dolphins swimming around and jumping out of the sea too. For many people, it would be a wonderful dream to swim with these lovely animals! However, this may not be good for dolphins. They may get hurt because of human interaction  . Dolphins are active and usually look for food at night. In the day, they like to rest in shallow bays . Many people think the dolphins are awake during the day as they swim. But when they sleep they rest half of their brain and keep the other half awake to breathe, so they may be sleeping even when they're swimming in the water. From 2010 to 2013, spinner dolphins   of Hawaii's Big Island were exposed to human activities more than 82 percent of the time, according to Julian Tyne, a researcher at Australia's Murdoch University. The National Oceanic and Atmospheric Administration (NOAA) says disturbing the animals in their near-shore habitat could force them to swim to less favorable places, putting them at risk of attack by sharks and other animals.  Besides, when people are around, dolphins become more active. Thus, they can't get enough sleep. "Disturbing their resting behaviors can actually affect their long term health and the health of the dolphin population," Ann Garrett of NOAA's National Marine Fisheries Service told the Associated Press. As a result, the NOAA wants to make rules to help protect the dolphins. For example, the agency   may ban swimming with the Hawaii spinner dolphins. Or they may stop people from swimming in shallow bays when the dolphins are resting. Tour operators must also be taught to watch for signs to know when the dolphins are in their resting state. Question: What does the article mainly talk about? Options: A: What habits dolphins have. B: What spinner dolphins are. C: How the animals live in the sea. D: How to protect dolphins near the shore.
A: D


Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Throughout history, people have been interested in knowing how languages first began, but no one knows exactly where or how this happened. However, we do know a lot about languages, the languages of today and also the languages of earlier times. There are probably about 3,000 languages in the world today. Chinese is the language with the most speakers. English, Russian and Spanish are also spoken by many millions of people. On the other hand, some languages in the world have less than one hundred speakers. There are several important families of languages in the world. For example, most of the languages of Europe are in one large family called Indo-European. The original   language of this family was spoken about 4,500 years ago. Many of the present day languages of Europe and India are modern forms of the language of 4,500 yeas ago. Languages are always changing. The English of today is very different from the English of 500 years ago. In time some even died out completely. About 1,000 years ago, English was a little-known relative of German spoken on one of the borders of Europe. If a language has a large number of speakers or if it is very old, there may be differences in the way it is spoken in different areas. That is, the language may have several dialects. Chinese is a good example of _ differences. Chinese has been spoken for thousands of years by many millions of speakers. The differences between the dialects of Chinese are so great that speakers of Chinese from some parts of China can't understand speakers from other parts. Question: According to the passage, most European and Indian languages   _   . Options: A: will soon die out completely B: were once a relative of English C: are no longer spoken D: come from the same family
A: D


Q: I'm taking a test and have to guess the right answer to the question after the article. Article: When you cut your skin, you bleed . If a person loses a lot of blood, he will become ill and may die. Blood is very important. People have always known that. At one time, some people even drank blood to make them strong! When doctors understand how blood goes around inside the body, they try ways of giving blood to people who need it. They take blood from the healthy people and give it to people who need it. This is called "blood transfusion". The blood goes from the arm of the healthy person into the arm of the sick person. But there are two problems. First, it does not always work. Sometimes people die when they have blood transfusion. Later, doctors find that we do not all have the same kind of blood. There are four groups--O, A, B and AB. We all have blood of one of these groups. They also find that they can give any kind of blood to people of group AB. But they find that they must give A-group blood to A-group people and B-group blood to B-group people. I have O-group blood and the doctor told me that I could give blood to anyone else safely. ks5u There is another problem. To give blood of the right kind, doctors have to find a person of the right blood group. Often they can not find a person in time. If they have a way to keep the blood until someone needs it, they can always have the right kind of blood. At first they find they can keep it in bottles for fifteen to twenty days. They do this by making it very cold. Then they find how to keep it longer. In the end they find a way of keeping blood for a very long time. We call a place where we keep money a "bank". We call a place where we keep blood a "blood bank". One day, when you grow up, you may decide to give blood to a "blood bank". In this way you may stop someone from dying. Or perhaps one day you may become ill. You may need blood. The "blood bank" will give it to you. Question: The writer doesn't talk about  _  in the passage. Options: A: how important blood is to us B: the four groups of blood C: where the blood bank is D: what "blood transfusion" is
A: C

"Many people in my country are very interested in China," he said, adding that these Americans have learned more about China's culture and the Chinese people.
