If it looks like a fish and swims like a fish, it usually is a fish. But not the new, lifelike robot fish developed by UK scientists, which have been swimming around the London Aquarium(水族館) as they wait for their release off northern Spain in 2011.

Equipped with tiny chemical sensors(傳感器),the fish will collect data on pollution in the port of Gijón and wirelessly send the information back to the control center.

“It’s a little lab onboard the fish,” said Rory Doyle, a scientist at BMT Group. The robots were designed, and are being built, by professor Huosheng Hu and his team at the University of Essex, UK.

The sensors will search for dangers such as chemical waste and will allow officials to map in real time the sources and effects of pollution, Doyle said. w_w w. k#s5_u.c o*m

He and his colleagues chose a fish design because hundreds of millions of years of evolution(進(jìn)化) has created an energy-efficient creature, he said. “Nature has done it very, very well.” But copying such a successful design comes at a cost: nearly 29,000 u.s. dollars per robot. m

The fish, therefore, will be built “robust” enough to handle any possibilities, Doyle said. They can’t get caught in nets easily, for instance, and the tracking systems inside can help the robot fish avoid crashes with boats and other things in the way.

So far, it also seems unlikely the robot fish will be mistaken: At the London Aquarium, sharks swim away from the fake fish, possibly because they find the robots electromagnetic fields(電磁場) unpleasant, Doyle said. w_w w. k#s5_u.c o*m

At the same time, scientists are working to ensure that the sounds of the robots and other factors don’t disturb the natural environment, he added.

The robot fish was developed in order to_______. w. k#s5_u.c o*m

A.be displayed on a robot exhibition in Spain

B.be sent to London Aquarium as a gift

C.get information of ocean pollution

D.collect data on the fishes in deep sea

According to Doyle, the robot was designed into fish shape in order to_______.

A.cut the cost of the robot

B.make the robot beautiful

C.reduce the sounds of the robot

D.make the robot work better with less energy

We can infer from the passage that the robot fish______. k#s5_u.c o*m

A.would send pictures of sea life back

B.would not be looked on as a real fish by fishes

C.could swim much faster than fishes like sharks

D.could help find new forms of energy in the sea

The underlined word “robust” in Paragraph 6 probably means_____.

A.small and light    B.big and heavy

C.smooth and soft    D.strong and smart

It is well known that the Japanese people’s love of fish is almost as a bee’s interest in honey. As fish populations were decreasing, fishing companies were forced to fish further and further away from the shore. Then they had a big challenge-h(huán)ow to keep the fish fresh for longer. So they decided to keep the fish stored in freezers on the boats. But the public did not like frozen fish. So again the fishing companies had a new bigger challenge. What they decided to do was to have fish tanks on their boats. After catching fishes, they would put them in the tanks and keep them living there until they got back to shore. But in this protected environment, lacking predators (掠食者),the fish stopped moving around. The Japanese public felt these dull fish did not taste fresh, which had an unpleasant effect upon sales. Once again the fishing companies had an even bigger challenge ...

Stop for a minute! Before we go any further, I would like to ask “What are your challenges? How do you handle an unexpected challenge?” May I think it this way that you should try to attack your challenges? Conquer(戰(zhàn)勝) them with a Swiss Army knife. Take the most proper and simple tool that you can adopt to deal with your situation.

Now back to our story. How did the Japanese finally figure out the fresh fish problem?Sharks! You might think the same. Sharks were caught and put into the tanks with other fishes. Don’t sharks eat fish? Well, they do eat a few fish, but they did also keep more fish active and alert (警覺的). The fish stay fresh because they are challenged.

Now, try to keep yourself fresh by finding your own shark to offer yourself a challenge in your own business and career.

The main reason for the fishing company to fish in the far sea was that         .

       A. the fish resource near the shore was on the decrease

      B. the fishes farther away from the sea tasted fresher         

C. people would prefer eating fresh fishes to less fresh ones

       D. it was getting harder and harder to keep fishes fresh

Which of the following statements is true?

       A. Japanese people love honey as much as a bee does.

B. The fish kept in tanks didn’t sell well because of their taste.

C. The fish stored in the protected environment tasted the best.

D. The fish kept in tanks didn’t taste fresh because they died before reaching the restaurant.

The underlined part of the last paragraph means “            .”

       A. If you went fishing, you might do as the fishing companies did

       B. Try to find a big shark, and you will meet your challenge

      C. To succeed in life, you should always be ready to meet challenges

       D. Sharks are usually compared to the challenges in people’s life

The purpose for the author to write the passage is to        .

       A. tell the readers “no pains, no gains”

       B. tell the readers how the Japanese keep the fish fresh

       C. advise readers to look for challenges to make progress

D. advise readers to find something difficult to do

A long time ago, before human beings lived on the earth, little coral polyps(水螅)settled around tropical (熱帶的)coastlines and constructed corals. Over a long period they created lots of reefs. Yet, pollution, climate change and commercial fisheries are limiting the chance of future generations knowing or seeing many of the reefs and sea creatures that exist. Hence, take action to dive now and you can explore the underwater world.
Commercial underwater diving began in ancient Greece. Diving in general means that the whole body is completely in water. On that account there are lots of exciting and quite adventurous ways to dive, like shark cage diving, scuba diving(戴水肺潛水)and reef diving.
There are great coral reefs all over the world, but usually they are situated in warm, clear water such as the Pacific and the Indian Ocean, where they grow best. This is why there are no coral reefs on the west coast of South Africa. However, South Africa’s east coast offers much brightly coloured sea life.
In South Africa more than 100,000 dives a year are made just in coral reefs, which are one of the natural wonders of the world. To see the whole beauty of the reef the right diving gear(設(shè)備) is an essential requirement. This means a perfect fitting diving mask and fins, as well as a snorkel(呼吸管)and a friend. Diving alone is dangerous because there may be strong currents you are not aware of, and it’s a lot more fun to share the experience with someone. However, before you can explore the deeper sea, a certificated and checked scuba, a wetsuit and of course a license will be needed. Whether you choose the snorkel or the scuba to spot the colourful underwater world, try to touch as little as possible, be careful with the corals and don’t strike the fishes, because the complex ecosystem is very sensitive.
【小題1】The following factors probably affect coral reefs EXCEPT ________.

A.sea creaturesB.pollutionC.fishingD.climate change
【小題2】Which of the following is true according to the passage?
A.Human beings appeared before corals were created.
B.One needs a license to dive into the deeper sea.
C.Diving alone has many advantages.
D.The origin of diving is in modern Greece.
【小題3】There are no coral reefs on the west coast of South Africa probably because of a lack of ________.
A.large waters and soft sand
B.warm currents and delicious food
C.friendly creatures and flat seabed
D.clear water and suitable temperature
【小題4】The last paragraph mainly tells us ________.
A.diving alone under the sea is rather dangerous
B.some matters we need pay attention to when diving
C.South Africa is a popular place for diving
D.what we should wear when diving
