dangerous experience I have ever had.
On the morning of the excursion,I met with my friends for breakfast,with little conversation.I supposed
we were nervous about the day ahead of us.The coach then drove us from Cape Town to Dyer Island in
Gansbaii.
As soon as we got to our destination,we were quickly pushed into a boat.About 2 hours into the boat
we spotted our first shark.It was one of the world's deadliest predators(食肉动物)-a Great White shark
Our guide told us that we had to get into the water immediately.Without any formal preparation or
instruction,we put our thick wet suits on and jumped into the iron cage.
There I was in this tiny cage with 3 Great White sharks circling around me.I tried desperately to take
pictures with my underwater camera,not letting my hands and feet drift(漂)out of the cage.
When I took a breath,life above the water seemed chaotic(混乱的)．But,I would drop back under
the water and life would seem to stop existing.And the sharks that always appeared frightening on TV or
in photographs actually appeared peaceful in person.
After an hour,I decided it was probably time for me to get out once the sharks started to become
really aggressive.I waited until the very last second I could,since I knew I would probably never do this
again.

About 97% of the world’s water is salty and is found in our oceans and seas. But, as we can’t drink sea water, how can it be important?
Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important sea water is!
Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains are delicately balanced.
The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didn’t matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop.
Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most countries have introduced fishing restrictions to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important sea water is!
46. Which of the following is the proper order of the food chain?
A. small animals→algae→microscopic animals→large animals→man
B. algae→microscopic animals→large animals→larger animals→man
C. small animals→algae→large animals→microscopic animals→man
D. microscopic animals→algae→large animals →larger animals→man
47. People used to think that the rubbish thrown into the sea ________.
A. wouldn’t harm the fish in the sea B. would change the balance of the food chain
C. would be broken down in the sea D. wouldn’t do much harm to the sea
48. From the passage, we learn that _________.
A. most fish and sea animals live at the surface of the seas
B. it is very difficult to break the balance of a food chain
C. excessive fishing has caused the decrease in fish stock
D. it won’t be long before the problems concerning oceans will be solved
49. Which of the following is NOT a way being used to protect oceans?
A. The use of international agreements.
B. Forbidding fishing to protect fish stocks.
C. The use of new techniques.
D. Raising people’s awareness of the need to protect oceans.
50. What would be the best title of the passage?
A. The importance of seawater.
B. Life in the oceans.
C. How to protect food chains.
D. How to deal with seawater pollution.
The Internationa1 Space Station allows astronauts to live in space for extended amounts of time, enabling them to explore the outside universe and conduct many experiments. However, nothing like that exists for our oceans, and thanks to the high water pressure, ocean researchers are able to explore what lies undersea for very short periods of time.
They are therefore never able to fully explore the deep inside areas of our oceans. However, if French architect Jacques Rougerie has his way, that will change soon.
Jacques has designed a ship that will allow researchers to spend a long period of time observing the sea life and conducting experiments. The huge l67ft. ship, named ‘Sea Orbiter’, consists of two areas—one above the water where the scientists and crew will live, and a lower pressurized deck (甲板), where scientists will be able to spend as much time as they wish. Since it is powered by sea currents and wind, he expects it to drift (漂流) along the oceans slowly, taking about two years to circumvent the globe.
Jacques will make their life as comfortable as possible in the ship. Besides being equipped with the latest sailing tools and communication equipment, the ship will also have a gym, a television and a DVD player! And these guys will not be eating freeze-dried food like astronauts. Instead, Jacques, an accomplished chef, plans on cooking them delicious meals every day.
The biggest problem to this giant ship is the cost, which is expected to be over $500 million—per ship! However, Jacques, who strongly believes that the secrets of our oceans may be the key to solving global warming and a vital supply for food and medicine in the future, is confident he will be able to convince governments all over the world to help out, and expects to start construction on not one, but four or five of these amazing ships soon!
1.Why can’t ocean researchers explore the deep oceans for a long time?
A. Because they can’t stand the high water pressure.
B. Because it’s too cold in deep ocean.
C. Because time for experiments is too limited.
D. Because it’s dangerous to observe the sea life.
2.The underlined word “circumvent ” probably means .
A. fly away B. go around C. travel through D. move into
3.From the fourth paragraph we can learn that .
A. Jacques intends to design the ship mainly for sightseeing and traveling
B. living a comfortable life helps to do the ocean research quickly
C. it’s much more expensive to eat freeze-dried food
D. researchers on Jacques ’ ship will live more comfortably than astronauts
4.In Jacques’ opinion, which of the following is not the purpose of the undersea research?
A. To find supply for food in the future.
B. To find supply for medicine in the future.
C. To draw governments’ attention to the construction of the ship.
D. To solve the global warming.
5.Which of the fol1owing would be the best title for the text?
A. Sea Orbiter—the ship of the future
B. A new way to explore the deep oceans
C. A great architect—Jacques Rogerie
D. Travel around the globe in Sea Orbiter

D
Antarctica is the southernmost place on Earth, and it is larger than the United Sates and 95% of it is covered with ice. The ice is 5 kilometers thick at places and it never melts. At least that is what we thought, but let us keep it that way for now.
The ice seems to be alive as it works its way towards the seA． It forms an ice shelf over the water. The edge breaks away from the shelf and falls into the seA． From here it drifts. Now big pieces of ice become icebergs that can be 160 km long. They now drift north until they finally melt and become part of the ocean. This process is part of a bigger process which in turn forms a cooling system for Earth. This is so important that no country is allowed to control this areA． The treaty (agreement) signed by 12 countries at first and later joined by more, was to prevent any country harming the planet with irresponsible behavior.
The treaty basically states that:
Antarctica can be used for peaceful purposes only.
No country may build a military base there.
No country may do a nuclear test there.
No country may dump nuclear waste there.
Scientists working there will share their information.
Some other rules are there to protect the penguins and seals.
No dogs may run loose.
No planes may land near large groups of animals.
No guns, explosives, or tractors may be used near the animals.
Most important is that every member can inspect any of the other bases if he suspects that the treaty rules are being broken.
While the treaty is not foolproof（万无一失的）, it does play a very important part in the protection of AntarcticA． The more people realize the effects that pollution has on this continent, the bigger the pressure will be on Governments to change the way they look at pollution.
69．Why was it important to sign a treaty for Antarctica?
A．Because the ice on Antarctica will finally melt into the ocean.
B．Because Antarctica is covered with 5 kilometers thick ice.
C．Because Antarctica balances the temperature of Earth.
D．Because there are many big icebergs in AntarcticA．
70．What is the process of the movement of ice in Antarctica?
A．Ice shelf---sea water---iceberg---ice.
B．Sea water---ice---iceberg---ice shelf.
C．Iceberg---ice shelf---ice---sea water.
D．Ice---ice shelf---iceberg---sea water.
71．What is included in the Antarctica treaty?
A．There is no secret research information in AntarcticA．
B．Dogs are not allowed to be raised in AntarcticA．
C．Waste can’t be thrown away in AntarcticA．
D．People can’t bring their guns to AntarcticA．
