Dive with Big Sharks
Our shark dive adventures make use of hookah systems and shark cages. A hookah system is a system of providing air from the surface to divers down below. Cage divers breathe by using a regulator connected to an air hose.
Is SharkDiving Dangerous?
Yes. You could get sunburnt. You could hit your head on the top bunk getting out of bed. You could fall overboard. As for a shark attack, according to the International Shark Attack File, you are far more likely to be killed by a dog or a deer.
Pricing & Details
One day Cage Diver Adventure $ 875
Our expert shark diver team will accompany you to the best viewing areas within the Marine Sanctuary. There, we'll drop our cage and prepare to provide you with a view you'll never forget.
No dive experience is necessary. Our cages sit just below the surface. You'll be able to breathe comfortably from your snorkel or air hose while you move about the cage, taking photos and having fun.

Brain cells work to actively forget memories during a specific period of sleep. When we sleep our brains clear out the memories we’ve made while we’re awake, deciding what to keep and what to get rid of. Forgetting is an active process, explained the authors of the study published in the journal Science. But less is known about this process during the different periods of sleep.
They found that during the rapid eye movement (REM ) sleep period — or active sleep when we are thought to dream — special nerve cells appear to actively contribute to forgetting. What are known as melanin-concentrating hormone-producing (MCH) neurons (神经元) sit in the hypothalamus (下丘脑): a part of the brain which helps with a range of functions such as sleep, appetite and emotions. Past research has suggested these cells help to control REM sleep patterns: activating the MCH neurons increasing time spentin this period, while preventingthemreducing changes into this period.
The scientists looked at MCH cells in mice, and found 52.8 percent were active during REM sleep, compared with 35 percent when the mice were awake. Study co-author Thomas Kilduff, director of the Center for Neuroscience at SRI International, told Newsweek the team was surprised to find that mice performed better on learning and memory tasks when the MCH cells were prevented. “This result suggests that activation of the MCH neurons may affect memory — that is, MCH neurons may facilitate forgetting,” Kilduff explained.
When asked what motivated the study, Kilduff said, “We hope the work could deepen our understanding of Alzheimer’s disease. Understanding the neural basis of learning and memory is a huge area of neuroscience research because of its effects on our everyday lives, as well as diseases such as Alzheimer’s disease. Prior to this work, no one suspected that MCH neurons had anything to do with forgetting,” said Kilduff.
4. What can we infer from paragraph 1?
A. Forgetting is a passive process.
B. The forgetting process is known to us.
C. Some memories are forgotten while we are awake.
D. Certain memories are removed while we are asleep.
5. What does the underlined word “them” in paragraph 2 refer to?
A. REM sleep patterns.
B. Past researches.
C. MCH neurons.
D. A range of functions.
6. Why did Kilduff’s team conduct the research?
A. To publish the study in the journal Science.
B. To know more about Alzheimer’s disease.
C. To contribute to human’s forgetting.
D. To explore our everyday lives.
7. What can we know about MCH?
A. MCH cells takes control of REM sleep patterns .
B. MCH neurons may disturb memory consolidation.
C. MCH neurons have nothing to do with forgetting.
D. MCH cells help mice performing better on learning.
C
One billion people in the world are short of water. How can this problem be solved. Some suggestions have been to desalinate ocean water or to build enormous water pipelines from areas where water is abundant. (Suggestions such as these prove extremely expensive when they are actually used.) One possibility that scientists are considering is pulling icebergs from either the North Pole or the South Pole to parts of the world with a water shortage. Although many questions must be answered before such a project could be tried, moving icebergs seems a reasonable possibility in the future.
Engineers, mathematicians, and glaciologists from a dozen countries have been considering the iceberg as a future source of water. Saudi Arabia is particularly interested in this project because it has a great water shortage. Scientists estimate that it would take 128 days to transport a large iceberg (about 1/2 square mile) to Saudi Arabia. Yet the iceberg would be completely melted by the 104th day. Therefore, insulation would be essential, but how
to insulate the iceberg remains an unsolved problem.
The problems in transporting an iceberg are numerous. The first problem is choosing the iceberg to pull. The icebergs that form in the North Pole are quite difficult to handle because of their shape. Only a small portion extends above the water — most of the iceberg is below the surface, which would make it difficult to pull. South Pole icebergs, on the other hand, are flat and float like table tops. Thus they would be much easier to move.
How can a 200-million-ton iceberg be moved. No ship is strong enough to pull such enormous weight through the water. Perhaps several ships could be used. Attaching ropes to an iceberg this size is also an enormous problem. Engineers think that large nails or long metal rods could be driven into the ice. What would happen if the iceberg splits into several pieces during the pulling. Even if an iceberg with very few cracks were chosen, how could it be pulled through stormy waters. Furthermore, once the iceberg reached its destination, very few ports would be deep enough to store it.
All of these problems must be solved before icebergs can become a reasonable source of water. Yet scientists estimate that it will be possible to transport them in the near future. Each year, enough icebergs form to supply the whole world with fresh water for a full year. In addition, icebergs are free and nonpolluting. As a solution to the world’s water problems, icebergs may be a workable possibility.
8. What is a problem in transporting iceberg?
A. The size of the iceberg.
B. The colour of the iceberg.
C. The salt in the iceberg.
D. The movement of air and water.
9. What is the author’ attitude towards transporting iceberg?
A. Pessimistic.
B. Objective.
C. Optimistic.
D. Unconcerned.
10. What does the last paragraph mainly tell us?
A. It is hard to use iceberg.
B. Iceberg are a good choice.
C. There are problems with iceberg.
D. Man finds no other ways to solve water shortage.
11. What can be a suitable title for the text?
A. Shortage of water.
B. Icebergs for water.
C. Scientists and icebergs.
D. Iceberg—scientists headache.
D
In 1990, Hal Donaldson was 23 years old, fresh out of college and found himself in Calcutta, India, where he was asked to interview Mother Teresa.
Donaldson says about the great woman famed for feeding the hungry, “She wasn't wearing shoes and her ankles were swollen. She sat down with me and was very polite.” After the interview, Mother Teresa asked him, “What are you doing to help the poor?” Donaldson admitted that he was young and wasn't focused on helping others. With a smile on her face, Mother Teresa said, “Everyone can do something.”
Those words deeply struck Donaldson and forced him to face some hard truths about himself.
Hal Donaldson grew up in the San Francisco Bay area. When he was 12 years old, his parents were hit by a drunk driver; his father died, and his mother was seriously injured. To make ends meet, they went on welfare. Donaldson says, “I had holes in my shoes and clothes. When you're teased at school for that, you just want to escape.”
He managed to do just that. Donaldson got into college and turned his focus to making money for himself He says, “I was just trying to find my way out of insignificance. However, it's easy to overlook others along the way. I was the guy that would see a homeless person and cross the street, so I didn'thave to confront (面对) him. My focus was on climbing to the top instead of helping those trying to climb with me.”
Donaldson returned home from India with a different thought. He traveled to eight cities in America and stayed on the streets and listened tostories of the homeless. “My heart broke,” he says. “I knew I could no longer just live for myself.”
Inspired by Mother Teresa's words and the stories he'd heard across America. Donaldson loaded a pick-up truck with $300 worth of groceries and handed them out to anyone who needed help. In 1994, Donaldson created the nonprofit organization, Convoy for Hope, which works with communities across America and around the world. Their work focuses on feeding children, women's empowerment, helping farmers and disaster services.
12. What did 23-year-old Hal Donaldson do in India?
A. He attended an interview for a college.
B. He fed the hungry with Mother Teresa.
C. He interviewed Mother Teresa.
D. He did something to help the poor.
13. What can we learn about Hal Donaldson from paragraph 4?
A. He was born with disability.
B. He led a hard life as a child.
C. He was well treated at school.
D. He survived as a parentless boy.
14. How does Hal Donaldson describe himself in college?
A. Self-centered.
B. Sympathetic.
C. Popular.
D. Casual.
15. How did Hal Donaldson change after he returned home from India?
A. He preferred traveling to volunteering.
B. He suddenly fell in love with journalism.
C. He turned his focus to living for himself.
D. He gradually devoted himself to helping others.

I still remember the sunshine that came in from the floor-to-ceiling windows of Pudong Airport on the morning of the 29th. It was brilliant and brilliant. The anxiety and excitement of careful thought were not obliterated（抹杀）by the three-hour rumbling sound, so that he almost lost his pass when he passed the customs.
The first thing I saw was the red double-decker airport bus, quietly nestling in the same bright sunshine in Hong Kong. The bus passed a bridge, followed by a green area, and then a bridge. On the sea were various cargo ships, unconsciously matching each other with color1 ful containers to create the color1 s of Hong Kong. The clouds are like cotton candy just out of the oven, densely crowded in the sky not too far away.
I started walking around on the first day. After packing my luggage at the hotel, I went to a small well-known "Yishun Milk Company" near Jordan. I ordered double skin milk and a portion of something else. I don’t remember the taste. I just remember that the uncles and aunts over there are very friendly. I sat under the air-conditioning blower silly to eat, and the uncle greeted me to change my seat and told me to be careful of catching a cold. It's really easy to have a good impression of a city. One sentence makes the mood as crystal clear as the weather in October.
Paragraph 1：
Then I went to the most prosperous area in Yau Ma Tei.
