The “swim with dolphins” tourist industry is becoming more popular recently. After all, it can cost a large amount of money to have this kind of holiday experience. So tour operators try to place eager swimmers as near as possible to the dolphins by trying to predict where the dolphins will be.
Research has shown that while dolphins can move away if they do not want to interact (交流) with human swimmers, they do not like it at all if the swimmers slip into the water directly on top of them or if humans are in their path of travel. However, if swimmers enter the water to one side of them, the dolphins do not avoid the swimmers to the same extent.
In all cases, the dolphins seem to have become more sensitive to the presence of the swimmers. For dolphins, swimming amongst or with humans is not necessarily a high priority. This study has shown that only 19% of any group of dolphins will participate in interaction. Young dolphins are the most likely to interact. It is believed that they see humans as “entertainment” and that the interaction is a new and unusual experience for them.
It is frequently asked whether “swim with dolphins” tourism should be discontinued. The advice is that dolphins should be given enough periods of time throughout the day when they are not exposed to tourism. Permitted interactions should not be too disturbing to the dolphins since there could be mothers and calves (幼崽) present in dolphin groups. There should also be educational campaigns about the creatures and what is likely to cause danger to them.
It is not easy to explain to someone that they cannot fulfill their lifelong dreams because the dolphins are resting, or that a mother dolphin and calf are in the area. But if we are to enjoy these remarkable animals and not just use them for our entertainment, then we must carefully monitor the “swim with dolphins” industry worldwide.
语篇解读：本文为说明文。“与海豚共游”这一旅游产业逐渐流行起来，研究者们就海豚的行为以及应如何控制这一旅游产业对海豚造成的影响展开了调研。
5．What makes “swim with dolphins” tourism popular
A．The local government's encouragement.
B．The improvement of people's living standard.
C．The increasing number of tourists.
D．The high profits of the industry.
解析：选D 推理判断题。根据第一段中的“After all, it can cost a large amount of money to have this kind of holiday experience”可知，这样的旅游花费不菲，言外之意就是其中的利益也不小。所以这个旅游产业越发流行的原因是其高利润。
6．Why are young dolphins more likely to swim with humans
A．They do this out of curiosity.
B．They like humans better.
C．They are less sensitive.
D．They prefer new things by nature.
解析：选A 推理判断题。根据第三段中的“Young dolphins are the most likely to interact. It is believed that they see humans as ‘entertainment’ and that the interaction is a new and unusual experience for them”可知，人们认为小海豚把人类当成它们的娱乐，把这种互动看成一种新奇且不寻常的经历。即出于好奇，小海豚更可能与人类一起游泳。
7．What does the author suggest the “swim with dolphins” industry do in Paragraph 4
A．Avoid interaction with young dolphins.
B．Strictly limit the expansion of the industry.
C．Make people know the hidden threat to dolphins.
D．Expose dolphins to tourists only in the daytime.
解析：选C 细节理解题。根据倒数第二段中的“There should also be educational campaigns about the creatures and what is likely to cause danger to them”可知，应该举办一些关于海豚以及可能对它们造成危害的事情这类话题的教育活动。因此，让公众了解可能给海豚带来的潜在威胁是减小对海豚造成消极影响的办法之一，故选C项。
8．What can be inferred from the last sentence of the passage
A．The industry has been a hot topic worldwide.
B．The industry aims to bring happiness to humans.
C．The industry enables humans to swim with dolphins.
D．The industry will harm dolphins without proper control.
解析：选D 推理判断题。根据最后一段的最后一句话可知，如果我们希望欣赏这些奇异的动物，而不仅仅把它们当成我们的玩物，那么我们必须要在全世界范围内谨慎地监控这项“与海豚共游”的旅游产业。由此可推断出，如果没有适当的控制，这一旅游业将会给海豚带来消极的影响。
Ⅴ.阅读七选五
As warming continues, scientists warn the oxygen content of oceans across the planet could be more and more reduced, with serious consequences for the future of fish and other sea life.
__1__ One is the simple fact that as water gets warmer, it can hold less dissolved (溶解的) oxygen. The other reason is less obvious. The entire ocean gets its oxygen from the surface — either from the atmosphere, or from photosynthesizing algae floating at the top of the sea. __2__
Global warming is expected to reduce the mixing of the ocean by making surface seawater lighter. That's because in a warmer world we can expect more rainfall and more melting (融化) of glaciers, icebergs, and ice sheets. __3__ The extra heat from the warming atmosphere will also make surface water expand and thus make it lighter still. __4__ Instead, more of the oxygen will remain near the surface, where it will be used up by oxygen breathing organisms.
A low oxygen ocean may become an inescapable feature of our planet. A team of Danish researchers wondered how long oxygen levels would drop if we could somehow reduce our carbon dioxide emissions to zero by 2100.They determined that over the next few thousand years oxygen levels would continue to fall, until they declined by 30 percent. The oxygen would slowly return to the oceans, but even 100,000 years from now they will not have fully recovered. __5__
A．It's not known why the oxygen level of oceans has reduced.
B．Scientists point to two reasons to expect a drop in ocean oxygen.
C．Fresh water's inpouring will make the water at the ocean's surface lighter.
D．The oxygen then spreads to the deep ocean as the surface water slowly sinks.
E．Global warming has caused the reduction of the oxygen content of oceans worldwide.
F．The light surface water will be less likely to sink so the deep ocean will get less oxygen.
G．If they are right, we have every reason to worry about the major effect it has on sea life.
答案：1～5 BDCFG

I was telling my boy Sonny the story of the hare (兔子) and the tortoise (乌龟). At the end I said, “Son, remember: Be slow and steady (镇定的), and that will win the race. Don't you think there's something to learn from the tortoise？”
Sonny opened his eyes wide, “Do you mean next time when I'm entering for the 60 metre race I should wish that Billy, Tony and Sandy would all fall asleep halfway？”
I was shocked, “But the tortoise didn't wish that the hare would fall asleep！”
“He must have wished that，” Sonny said, “Otherwise how could he be so foolish as to race with the hare He knew very well the hare ran a hundred times faster than he himself did.”
“He didn't have such a wish，” I insisted. “He won the race by perseverance (坚忍不拔), by pushing on steadily.”
Sonny thought a while. “That's a lie，” he said. “He won it because he was lucky. If the hare hadn't happened to fall asleep, the tortoise would never have won the race. He could be as steady as you like, or a hundred times steadier, but he'd never have won the race. That's for sure.”
I gave up. Today's children are not like what we used to be. They're just hopeless.
语篇解读：这是一篇记叙文。文章主要讲述了作者想让儿子从龟兔赛跑的故事中得到一些启示，然而儿子却有不同的观点，认为乌龟取胜不是因为它的坚忍不拔，而是幸运所致。1．The writer argued with his son because ________.

Larry was on another of his underwater expeditions (探险) but this time, it was different. He decided to take his daughter along with him. She was only ten years old. This would be her first trip with her father on what he had always been famous for.
Larry first began diving when he was his daughter's age. Similarly, his father had taken him along on one of his expeditions. Since then, he had never looked back. Larry started out by renting diving suits from the small diving shop just along the shore. He had hated them. They were either too big or too small. Then, there was the instructor. He gave him a short lesson before allowing him into the water with his father. He had made an exception. Larry would never have been able to go down without at least five hours of theory and another similar number of hours on practical lessons with a guide. Children his age were not even allowed to dive.
After the first expedition, Larry's later diving adventures only got better and better. There was never a dull moment. In his black and blue suit and with an oxygen tank fastened on his back, Larry dived from boats into the middle of the ocean. Dangerous areas did not prevent him from continuing his search. Sometimes, he was limited to a cage underwater but that did not bother him. At least, he was still able to take photographs of the underwater creatures.
Larry's first expedition without his father was in the Cayman Islands.There were numerous diving spots in the area and Larry was determined to visit all of them. Fortunately for him, a man offered to take him around the different spots for free. Larry did not even know what the time was, how many spots he dived into or how many photographs he had taken. The diving spots afforded such a wide array of fish and sea creatures that Larry saw more than thirty varieties of creatures.
Larry looked at his daughter. She looked as excited as he had been when he was her age. He hoped she would be able to continue the family tradition. Already, she looked like she was much braver than Larry had been then. This was the key to a successful underwater expedition.
语篇解读：Larry带着他10岁大的女儿到海底探险，并回顾了Larry自己在女儿这个年龄时他的父亲带他去海底探险的经历。他希望女儿能继承他的家族传统，因为女儿有“勇敢”这一海底探险成功的关键要素。
5．In what way was this expedition different for Larry
A．His daughter had grown up.
B．He had become a famous diver.
C．His father would dive with him.
D．His daughter would dive with him.

A．Larry had some privileges.
B．Larry liked the rented diving suits.
C．Divers had to buy diving equipment.
D．Ten year old children were permitted to dive.
解析：选A 推理判断题。根据第二段的“He had made an exception ... Children his age were not even allowed to dive.”他这个年龄段的孩子是不准潜水的，可知他得到了特权。
7．Why did Larry have to stay in a cage underwater sometimes
A．To protect himself from danger.
B．To dive into the deep water.
C．To admire the underwater view.
D．To take photos more conveniently.
解析：选A 细节理解题。根据第三段“Dangerous areas did not prevent him from continuing his search.”可知他待在笼子里是为了保护自己，避免危险。
8．What can be learned from the underlined sentence
A．Larry didn't wear a watch.
B．Larry was not good at math.
C．Larry had a poor memory.
D．Larry enjoyed the adventure.
解析：选D 句意理解题。根据第四段“There were numerous diving spots in the area and Larry was determined to visit all of them. Fortunately for him, a man offered to take him around the different spots for free.”可知他到了许多地方，非常喜爱冒险。PAGE

A
Even after centuries of exploration, the ocean still holds its mysteries. Although we know more today about the world's oceans and creatures living in them than ever before, every once in a while the sea brings up something so strange, so unexpected, that makes the world wonder what it could be.
Such was the case when the currents (水流) of the Mediterranean Ocean recently washed a 13 foot long, smelly body onto the shores of the village of Villaricos in Andalusia, Spain. An early report in the Spanish publication Lavante described the strange, horned (带角的) body as what might seem like a big fish, but it was already in pieces. Locals joked that it was some kind of Loch Ness Monster.
The media jumped right on the creature, of course. Some sites called it a horned sea monster. The popular newspaper Boing Boing called it a dragon. Some people guessed that it might be an oarfish, which is actually a rarely seen kind of big fish that can grow up to 55 feet long.
But now the experts have weighed in and we're sorry to report that it's not a dragon, a Loch Ness Monster, or even an oarfish.“That is actually a shark skeleton (骨架)，” Professor Grubbs from Florida State University told NBC News.“The parts toward the back were confusing me, but those are the lower caudal fin (尾鳍) supports. The ‘horns’ are the scapulocoracoids which support the pectoral fins (胸鳍)．” Scapulocoracoids are backbones common to many animals.
So there we go, another mystery solved. Well，the ancient maps that once described areas of the ocean as places of dragons have yet to be proven true. But it's good to know that the ocean still has a few surprises for us, even in cases where they're just dead, smelly bodies.

Nicola MacFarlane, 41, and her daughter Lucy, four, from Portobello, near Edinburgh, were playing on the Portobello Beach when they came across an old glass bottle sticking out of the sand containing a note inside written in Chinese.
It is unclear when the letter was sent off, but it was written on Chinese Valentine's Day, or Qixi Festival as it is more traditionally known, which falls on the seventh day of the seventh lunar month.
Whether the message has traveled thousands of miles from China or whether it was penned by a love struck pair much closer to home may remain a mystery. But for Nicola it doesn't matter — she is still excited to read about the Chinese love story after having it translated. She said, “I really do hope that it is from China but even if it is from someone nearer to home, it's still a lovely gesture and an inspiring find. It's a love story regardless of where it came from.”
“We saw the bottle sticking out of the sand and just thought it was junk that someone had left behind. But after picking it up I noticed there was a piece of brown paper rolled up inside and there was some foreign writing on it. We quite excitedly took it home, carefully opened the bottle and took out the sheet of paper using some tweezers (镊子). We knew it was Chinese, but we had no idea what it said.”
Unable to read the Chinese text, Nicola turned to the Internet and her Australian friend, Julie Gould, whose daughter attended a Chinese school in Sydney. Several hours later Julie returned with the news that it was in fact a love letter.
Nicola said, “It sounds to me like the couple are in love but cannot be together so they have sent the message to tell the world of their love. I'm blown_away by it to be honest — it's incredible that it has traveled all this way.”
语篇解读：Nicola和4岁的女儿在英国爱丁堡附近海滩发现了一个藏在沙子里的玻璃瓶，瓶子里装有一封用中文写的情书，它可能从中国漂流而来，真是太不可思议了。
4．Nicola thought the bottle was thrown into the sea because ________.
A．the sender wanted to find a true lover through the letter
B．the sender expected to find a partner who liked Chinese
C．a couple couldn't stay together and showed their love in this way
D．a couple fell in love with each other and wished their love to last forever
解析：选C 细节理解题。从最后一段“It sounds to me like the couple are in love but cannot be together so they have sent the message to tell the world of their love”可知，这是一对相爱的情侣，由于不能在一起，所以他们通过漂流瓶来告诉全世界他们的爱。
5．The underlined phrase “blown away” in the last paragraph probably means “________”．
A．depressed B．frightened
C．embarrassed D．impressed
解析：选D 词义猜测题。从最后一段“it's incredible that it has traveled all this way”可知，它一路漂流而来，真是太不可思议了，blown away应与incredible(难以置信的)有相近的意思，根据选项，D项impressed(印象深刻的，感动的)的意思与之最接近。
6．Which of the following words can best describe Nicola's feelings about the letter
A．Curious and excited.
B．Cautious and excited.
C．Doubtful and delighted.
D．Curious and dissatisfied.
解析：选A 推理判断题。根据全文可知，Nicola捡到漂流瓶后，由于好奇，兴奋地把它带回家，然后求助了她的澳大利亚朋友翻译信件内容。由此可知A项正确。

It was a village in India. The people were poor. However, they were not unhappy. After all, the forefathers had lived in the same way for centuries.
Then one day, some visitors from a city arrived. They told the villagers there were some people elsewhere who liked to eat frog's legs. However, they did not have enough frogs of their own, so they wanted to buy frogs from other places.
This seemed like money for nothing. There were millions of frogs in the fields around, and they were on no use to the villagers. All they had to do was catch them. Agreement was reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the frogs and hand over the money. For the first time. the people were able to dream of a better future. But the dream didn't last long.
The change was hardly noticed at first, but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often, and, there seemed to be more insects around lately.
The villagers decided that they couldn't just wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides (杀虫剂) and medicines. Soon there was no money left.
Then the people realised what was happening. It was the frog. They hadn't been useless. They had been doing an important job — eating insects. Now with so many frogs killed, the insects were increasing more rapidly. They were damaging the crops and spreading diseases.
Now, the people are still poor. But in the evenings they sit in the village square and listen to the sounds of insects and frogs. These sounds of the night now have a much deeper meaning.
