1 . A blue hole is a special kind of underwater cave found inland or in the sea, which forms when the earth above a cave falls in and water fills the space.
An inland blue hole’s water is very still and has different layers. A layer of fresh rainwater floats on top of salt water; the fresh water keeps oxygen from the atmosphere from reaching the salt water; brightly colored bacteria live where the two layers meet.
Diving into blue holes is very dangerous. Near the top of the blue hole, there is a layer of toxic gas, which causes itching, headache, and—in large amounts—death. Divers must also be fast. They have to get in and out of a cave before their oxygen runs out. Additionally, divers have to follow a guideline as they swim through a blue hole because it is very dark inside. Without the guideline, they may get lost.
If blue holes are so dangerous, why do explorers and scientists risk their lives to explore them? The reason is that these underwater caves can provide valuable scientific information. They provide clues about geology, archaeology, and biology. For example, some blue hole creatures probably haven’t changed for millions of years.
The blue holes could even provide clues about astrobiology. For example, divers have found bacteria there that can live without oxygen. Astrobiologist Kevin Hand says the bacteria may be similar to forms of life that might exist on Jupiter’s fourth largest moon, Europa. “Our study of life’s extremes on Earth,” he says, can help increase “our understanding of habitable environments off Earth.”
In addition, the oxygen-free environment of the blue holes preserves bones of humans and animals that fell into the caves long ago. By studying blue holes, we can understand what life was like in prehistoric times. As cave diver Kenny Broad says, “I can think of no other environment on Earth that is so challenging to explore and gives us back so much scientifically.”

3 . Friends always ask why I, a middle-aged woman with no athletic (运动) talent (天赋), travel to perilous places — the jungles (丛林) of Thailand or Borneo, for example, where the water is often unsafe and the food risky; places with infectious diseases, poisonous snakes and the wildest animals.
I never know how to answer. Nine years ago I suffered a stroke (中风). To prevent another stroke, my doctors told me, I’d have to take dangerously high levels of blood thinner (血液稀释剂) for the rest of my life and any travel would be risky (冒险的).
I had to think about what was important to me: family, of course, and friends. But then what? No matter how many times I thought about it, I could not be happy without travel. Then I had to decide how I might manage the risk.
The first real test of my travel courage came nine months after my stroke when I joined my husband, Jack, on a business trip to China. After we’d toured the remains of a Tang dynasty temple on a high mountain, Jack wanted to ride down on a toboggan (长雪橇).
Before the stroke it would’ve seemed like fun. But now? I hesitated. My mental klaxon (高音喇叭) screamed warnings about the consequences of a cut, a fall, and a crash. Then, gaining confidence from who knew where, I lowered myself carefully into the toboggan, which marked my adventure (冒险) travel come back.
In the years since then, I’ve traveled about twenty-five percent of the time. Through it all, my lucks held out — no deadly falls, no car accidents or serious infections. For me, adventure travel is a risk worth taking. Travel broadens my world and keeps me connected to nature. What’s more, saying “yes” to travel keeps me connected to myself.

4 . What makes people so special? Tool use, self-consciousness, language, and culture are high on the list, but in fact all of these characteristics can be found elsewhere in the animal kingdom. Humans and apes are close relatives, so it is perhaps not surprising that chimpanzees use tools or that gorillas (大猩猩) have a sense of fair play, even rejecting carrots (which they normally accept) when they see their neighbors getting grapes. But the qualities that we often think of as uniquely human exist not just on land, but in the ocean as well.
Among the invertebrates, octopuses (八爪鱼) are known for their intelligence, even exhibiting evidence of playfulness, tool use, and personality. But these skilled predators live alone and consequently lack culture. Dolphins, on the other hand, are large-brained, long-living, social- group-based predators, and it is here that we find the greatest similarity to human-like culture and awareness.
Culture depends on the ability of animals to pass on things they have learned to others. Many animals have culture in this sense, but what sets dolphins apart is what they pass on. Some bottlenose dolphins hold sponges in their mouths that they use as tools to sweep for fish hiding on the ocean floor. This ability is handed down through generations (especially in females), with some families — grandmother, mother, and daughter — all feeding in this highly specialized way.
Another characteristic that dolphins share with humans is their ability to recognize themselves in a mirror. When facing a mirror, most animals behave as though they are interacting with another individual. Even in humans, the ability to recognize that the image in a mirror is oneself does not occur before the age of 18 months. Dolphins not only recognize themselves, but if a black mark is put on the body of a dolphin, it will spend extra time at the mirror to look at the mark.

| B．Dolphins are as intelligent as a typical 18-month-old human baby. |
| C．Dolphins are generally regarded as the most advanced non-human species. |
| D．Dolphins’ ability to recognize their own reflection is a higher-order mental skill. |
A funny thing happened to Arthur when he was on the way to work one day. As he walked along Park Avenue near the First National Bank, he heard the sound of someone trying to start a car. He tried again and again but couldn’t get the car moving. Arthur turned and looked inside at the face of a young man who looked worried.
Arthur stopped and said, “It looks like you’ve got a problem.”
“I’m afraid so. I’m in a big hurry but I can’t start my car.”
“Is there something I can do to help?” Arthur asked. The young man looked at the two suitcases in the back seat and then said, “Thanks. If you’re sure it wouldn’t be too much trouble, you could help me get these suitcases into a taxi.”
“No trouble at all. I’d be glad to help.”
The young man got out and took one of the suitcases from the back seat. After placing it on the ground, he turned to get the other one. Just as Arthur picked up the first suitcase and started walking, he heard the long loud noise of an alarm.
It was from the bank. There had been a robbery (抢劫)!
Park Avenue had been quiet a moment before. Now the air was filled with the sound of the alarm and the shouts of people running from all directions. Cars stopped and the passengers joined the crowd in front of the bank. People asked each other, “What happened?” But everyone had a different answer.
Arthur still carrying the suitcase, turned to look at the bank and walked right into a young woman in front of him.
She looked at the suitcase and then at him. Arthur was surprised. “Why is she looking at me like that?” he thought. “The suitcase! She thinks I’m the bank thief!”
Arthur looked around at the crowd of people. He became frightened, and without another thought, he started to run.

8 . London and Paris are two of Europe’s biggest tourist destinations, just a few hours away from each other by road or rail and an hour’s distance by air. What about the train-ferry combination that many recall fondly from their childhoods? Well, though it’s budget-saving, this option is too time-consuming today, so better leave it to your memories. Since the UK is not part the Schengen Area, passengers need to go through passport control prior to boarding.
Air trips
Though flying between London and Paris is by no means recommended, there are still a few people traveling between the two dynamic cities by air. A very low one-way fare is possible through advanced booking, but of course it’s rare, and that doesn’t include the taxi and rail fares traveling to and from the airports.
* One-way fares from Paris can be as low as 49;
* From London, Air France flies with fares as low as £39(46), and British Airways as low as £48 (56).
Rail trips
The only direct train between London and Paris is the Eurostar, which travels 15 -17 times per weekday. Eurostar’s 2015 edition trains can make the journey in two hours at speeds of up to 320 km/h. Besides, they offer good seating space.
* Fares begin at a reasonable £58(68), round trip;
* The earlier you book, the more you save.
Bus trips
The bus is by far the least expensive and longest way to travel between Paris and London. Eurolines and OUIBUS are two major bus lines traveling between the two capitals. The journey takes between seven and nine hours. Both lines advertise free Wi-Fi.
* One-way Eurolines fares begin at 15;
* One-way OUIBUS fares begin at 15 too, but early bird sales can even lower the fare.

The Class Poet(诗人)
When Thanksgiving Day was approaching (临近), my primary school decided to celebrate(庆祝 ) by presenting shows with dancing and singing that all students could join in. Parents would also be invited to watch.
One afternoon, my teacher called me into his office. He said with a smile, “Nancy, could you write a poem (诗) and read it during the coming event?” “Of course,” I answered excitedly. I had loved poetry since fifth grade. When my first poem was published, my friends and teachers started to describe me as the class poet.
I left the schoolmaster’s office that afternoon feeling quite happy. Then, for weeks, I worked on my poem, carefully designing the content, structure and sound. I practiced reciting(朗诵)it aloud every day.
When the evening for the event finally came, I was ready. Well, I was ready until I looked around and realized how many people there were in the school hall. How could I present my poem in front of more than 400 people? I was just a seventh-grader. No one would take my work seriously. What was worse, I had never spoken in front of a huge crowd before. I sat in my chair, wanting to bury(隐藏) myself. Maybe they would forget I was supposed to read.
“Hey, Nancie, I saw your name in the program. Good luck,” my little brother shouted. His voice rose as he took his seat a few rows (排)down with his class. I nodded (点头), struggling to keep calm. I knew my parents were somewhere in the hall. Before long, the lights faded (暗下来), the crowd went quiet, and the schoolmaster got on stage to introduce the list of performers. My name was at the end of the list, so I had to sit through an hour of absolute anxiety.
It wasn’t until the students from the fourth grade were singing that my teacher led me downstairs to the area next to the stage. My mind was blank (空白的). Then suddenly, I was on stage with the bright white lights blinding (使眼花) my view of the audience. When I walked to the microphone in the center of the stage, I somehow tripped (绊倒) over something and stupidly fell down. All of the kids burst into laughter.
