Read the article and select the best answer. Article: 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. Question: What can we learn about dolphins according to the text? Options: A: A dolphin gets its food from its mother. B: Dolphins communicate a lot with one another. C: Dolphin conversations are easy to understand for men. D: Dolphins communicate by whistling instead of using body language.

Q: Read the article and select the best answer. Article: Many cities in the world are benefiting from the night activities of a group of people who call themselves guerrilla gardeners. Armed with trowels, spades and a van full of flowers and plants, guerrilla gardeners turn abandoned urban land into a blaze of color. In city centre locations where there was mud, weeds and empty plastic bottles, residents often wake up to find that the wasted area has been transformed overnight with brightly-colored bedding plants. In most British cities, local governments and police turn a blind eye to the effort of the gardeners, whose activities are always carried out under cover of nightfall. And so far, there has been nothing but praise from the astonished and delighted local residents when they find their neighborhood transformed in such a striking fashion. Not only do the guerrilla gardeners beautify neglected places, they also return regularly to water the plants and weed the flower beds. They also make sure that at least some of the plants they bring are evergreens, which means that the area doesn't look depressing in the winter months. The first guerrilla gardener in London was Richard Reynolds, whose day job is at an advertising agency. Mr. Reynolds, a graduate of Oxford University, began his efforts two years ago when he moved to a flat in a tower block in South London. From his balcony, he could see several empty concrete pots, placed by the local governments to contain plants but never used. He went out after midnight and filled the pots with plants, and then planted more flowers in the path leading to the entrance to the block. He then set up a website to explain his plan and called upon more gardeners to join him. Cash donations flooded in and, more importantly, volunteers rushed to be part of the campaign. Within six months, there were five hundred people in London prepared to come out at very short notice to restore neglected parts of the urban landscape. There are now unofficial but carefully-organized groups in many cities in Britain and North America and there... Question: These guerrilla gardeners do their work _ . Options: A: at the request of the government B: nearby their house C: often in return for others' help D: out of their own free will

(Question)
Read the article and select the best answer. Article: Someday a stranger will read your email without your permission or scan the website you have visited. Or perhaps someone will casually glance through your credit card purchases or cell bills to find out your shopping preferences or calling habits. In fact, it is likely that some of these things have already happened to you. Who would watch you without permission? It might be a girlfriend, a marketing company, a boss or a criminal. Whoever it is, they will see you in a way you never intended to be seen----- _ stcentury is the equal of being caught naked. Psychologists tell us boundaries are healthy and that it is important to reveal yourself to friends, families and lovers at appropriate time and places. But now few boundaries remain. The information you leave everywhere makes it easy for strangers to reconstruct who you are, where you are and what you like. Believe it or not, we live in a world where you simply can't keep a secret. The key question is: does that matter? When you ask Americans about privacy, most say they are concerned about losing it. But people say one thing and do another. Only a tiny part of Americans change any behaviors in an effort to preserve their privacy. Few people turn down a discount at tollbooths to avoid using the EZ-Pass system that can track automobile movements. And few refuse to offer personal information like Social Security numbers to get supermarket loyalty cards. But privacy does matter--at least sometimes. It is like health: when you have it, you don't notice it. Only when it is gone do you wish you had done more to protect it. Question: Which of the following may serve as the best title of the passage? Options: A: Privacy and Health B: Privacy Is Getting Lost. C: Boundary and Friendship D: Cherish What You Have
