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. Question: What is the text mainly about? - The comparison between dolphins and humans. - The relationship between dolphins and humans. - Different types of dolphins. - The habitual behavior of dolphins.

Ques: Read the following article and select the best answer. Article: A rainfores is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16degC.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere,warming the rest of the world .Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world. In the past hundred years, humans have begun destroying rainforests in search of three major resources : land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit . There are two main reasons for _ . Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world' s wood supply. Rainforests are often called the world's drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world's shrinking rainforests. Question: ..Rainforests can help to adjust the climate because they _ . - reflect more heat into the atmosphere - bring about high rainfall throughout the world - rarely cause the temperature to drop lower than 16degC - reduce the effect of heat from the sun on the earth
Ans: reduce the effect of heat from the sun on the earth

Read the following article and select the best answer. Article: Who are the elders in your family? The most common answer is that they are your parents, grandparents, uncles, aunts, and elder cousins ------in a word, any who is older than you. But that doesn't really answer the question, does it? In a normal family, there is a big difference between being elderly and being an elder. Elders are the storytellers, the cooks, the historians, the authorities, the knitters, and the workhorses. They are the people we respect and turn to for answers or help when we are in trouble, because of their many years of life experience. Most of all, they are the people who raised you and your loved ones and helped you growing into the people you are. For many years, they carried the burden of caring for your family and leading it to better times. Now it's your turn to dote on them. Ensuring the welfare of your elders should come as naturally to us as raising our children. Unfortunately, too many people take their parents' and grandparents' ability to care for them for granted. And in a country where so many of us live hundreds of miles from our families, looking after loved ones can be difficult. Even so, you should make sure your loved ones are taken care of no matter where they live, and try to look after the seniors living alone in your neighbor, too. Taking responsibility for the elders in our society in an important thing that all citizens should do. Question: Which of the following opinions doesn't the author agree with? - naturally that the elders should take care of themselves - It's our duty to take care of the elders when they are old - We should take care of the elders even if a long distance separates us from them - Looking after the elders is as important as raising our children
naturally that the elders should take care of themselves
