Dolphins are interesting animals and researchers find them interesting to watch. They don't have hands, but can use tools to solve problems, just like us. Scientists have observed a dolphin trying to get a shy eel to come out of its hole by poking it with a dead fish. Many species of dolphin live in large societies. They have many different relationships and need a good communication system; they use a variety of sounds to communicate with each other. There is currently no evidence that dolphins have a language of their own. But scientists still have a lot to find out about these animals and so there are certain to be a few surprises in the future. At Kewalo Basin Marine Laboratory in Hawaii, the dolphin team have developed a sign langue to communicate with the dolphins, and the results are amazing. Not only do the dolphins understand the meaning of individual words, they also understand the significance of word order in a sentence. For example, when they were asked to 'touch the ball with your tail and then jump over it' they generally responded correctly and straight away, which showed that they understood the langue. Most mammals seem to enjoy play--but dolphins seems to like making their games as challenging as possible. On a beautiful day in 1997, researchers working at a beach, off the southern coast of Brazil, observed a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins approached the dog and then started throwing it into the air. The dog seemed to enjoy the 'game' and continued playing with the dolphins for more than an hour. From then on, different dogs were seem trying to interact with the dolphins. Dolphins live in a very different world to ourselves, but they are very good at our 'intelligence tests'. For example, they will jump out of the water when they hear a whistle noise. They do this because they will get a fish as a reward. There is still much to learn about these flexible problem-solvers, but from the evidence so far, it would seem as though... To get a shy eel to come out of its hole , a dolphin would poke it with _ . A) a tool B) its tail C) a dead fish D) its mouth

Life is full of change, and this leads to growth. Change is what keeps our lives moving, and allows us to achieve what we desire and deserve. Like it or not, we need to be willing to go with the flow, and be adaptable when something doesn't go according to plan. A catalyst is a person that causes something else to happen, and if you're not currently a catalyst for change, here are some things you can do to become one. Take a look at what you've got going on in your life right now. Write down everything that comes to mind. Is there anything that jumps out at you that you're not content with? Is there something that isn't moving forward as quickly as you would like it to? Identifying what you want to change is the first step to getting somewhere with it. Take the initiative to make change happen. Once you have identified what you want to work on changing, write down several possible "next steps" you can take to realizing that change. Whatever it is you want to change, you won't get very far without having specific actions in mind to carry out. Start small, and then focus on items that are a bit more involved or difficult and just keep going! When carrying out a change, it's great if you're able to _ , particularly if they can help you implement that change in some way. Be receptive to feedback, but realize that others' opinions are not golden. Also remember to give feedback when asked for it. Be sure it's genuine and that you are able to stand behind it. Create an environment for change. There is nothing more discouraging than trying to create change in an environment that is not conducive to it. It's like trying to stick to a diet in a house that is filled with chips, cookies, ice cream and chocolate; you are just making it more difficult for yourself. Change is good, and often leads to process improvement, increased productivity and efficiency. Take the initiative, and make changes to your life to get to where you want to go faster than you are going right now. What can we infer from the text? A) Change benefits us in different ways. B) Creating a good environment is the most important step. C) It's discouraging to try to change one's environment. D) Being a catalyst for change is risky but rewarding.

In the early days of nuclear power, the United States make money on it. But today opponents have so complicated its development that no nuclear plants have been ordered or built here in 12 years. The greatest fear of nuclear power opponents has always been a reactor "meltdown". Today, the chances of a meltdown that would threaten U.S. public health are very little. But to even further reduce the possibility, engineers are testing new reactors that rely not on human judgment to shut them down but on the laws of nature. Now General Electric is already building two advanced reactors in Japan. But don't expect them even on U.S. shores unless things change in Washington. The procedure for licensing nuclear power plants is a bad dream. Any time during, or even after, construction, an objection by any group or individual can bring everything to a stop while the matter is investigated or taken to court. Meanwhile, the builder must add nice-but-not-necessary improvements, some of which force him to knock down walls and start over. In every case when a plant has been opposed, the Nuclear Regulation Commission has ultimately granted a license to construct or operate. But the victory often costs so much that the utility ends up abandoning the plant anyway. A case in point is the Shoreham plant on New York's Long Island. Shoreham was a virtual twin to the Millstone plant in Connecticut, both ordered in the mid-60s. Millstone, completed for $101 million, has been generating electricity for two decades. Shoreham, however, was singled out by antinuclear activists who, by sending in endless protests, drove the cost over $5 billion and delayed its use for many years. Shoreham finally won its operation license. But the plant has never produced a watt power. Governor Mario Cuomo, an opponent of a Shoreham start-up, used his power to force New York's public-utilities commission to accept the following settlement: the power company could pass the cost of Shoreham along to its consumers only if it agreed not to operate the... Governor Mario Cuomo's chief intention in proposing the settlement was to _ . A) stop the Shoreham plant from going into operation B) urge the power company to further increase its power supply C) permit the Shoreham plant to operate under certain conditions D) help the power company to solve its financial problems
