It is becoming increasingly important for researchers to closely monitor our ocean life. However, observing sea creatures up close is almost impossible since human presence scares them. Now, thanks to the The Soft Robotic Fish, also known as SoFi, researchers may be able to keep a close eye on the sea creatures.
Built by MIT Computer Science and Artificial Intelligence Laboratory (CSAIL), the white remote-controlled robot resembles the real fish, complete with a tail that waves from side to side. Though not the first autonomous underwater vehicle (AUV) created to monitor the ocean, SoFi settles many of the problems that have blocked the usefulness of previous robot fish.
Previous AUVs have had to be linked to boats because of radio frequency communications don’t work well underwater. To overcome the problem, Director of the CSAIL Daniela Rus and her team used sound waves. The technology can travel greater distances allowing divers to pilot SoFi from up to 50 feet away.
Also limiting the usefulness of traditional AUVs is the risk of collision. With the outside made of soft silicone (硅树脂) rubber and flexible plastic that keeps its inbuilt electronics dry, SoFi poses no such danger. “Collision avoidance often leads to unnecessary movement, since the robot has to settle for a collision-free path,” says Rus. “ In contrast, a soft robot is not only more likely to survive a collision but also could use it as information to form a more workable movement plan next time around.”
During test dives, SoFi moved alongside the ocean life at depths of 50 feet for up to 40 minutes at a time, taking photos and making videos. The researchers say sometimes the fish would swim alongside the strange-looking robot-fish out of curiosity, while at other times they took no notice of its existence.
While SoFi presently only records video, future versions will include sensors. The researchers also hope to make it more autonomous. “We imagine someday it might help us uncovers more secrets from the amazing underwater world that we know so little about,” says Rus.
1.What can we learn about SoFi?
A. Its tail is flexible. B. It is the first AUV.
C. It is closely controlled. D. Its presence scares sea animals.
2.What can be learned from paragraph 3?
A. Sound waves travel faster than radio.
B. Radio does not work well underwater.
C. Previous AUVs use radio to communicate.
D. A boat travels along with SoFi on the water.
3.How does SoFi differ from traditional AUVs?
A. It is controlled above.
B. It can avoid a collision.
C. It can smartly adjust its movement plan.
D. It is set for a collision-free path.
4.Where is the passage possibly taken from?
A. A news report. B. A science fiction.
C. A social website. D. A short biography.

It is becoming more and more important for researchers to closely observe our sea life, with climate change and overfishing damaging our oceans. However, this is almost impossible since human presence scares the animals. Now, thanks to The Soft Robotic Fish, also called SoFi, researchers may not only be able to keep a close eye on the creatures, but also uncover undersea secrets that have been confusing us for centuries.
Built by MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL), the snow-white remote-controlled robot closely emulates real fish, complete with a flexible tail and two "fins". Though not the first autonomous underwater vehicle (AUV) created to observe the oceans, SoFi solves many of the issues that have hindered (妨碍)the usefulness of previous robots.
AUVs traditionally have had to be tied to a boat because radio frequency communications do not work well underwater. To solve the problem, CSAIL director Daniela Rus and her team used sound waves which can travel greater distances, allowing drivers using a waterproofed Super Nintendo controller to pilot SoFi from up to 50 feet away. To ensure SoFi can freely move around the ocean, a pump moves water from one balloon-like structure to the other through its soft rubber tail, while a controller fitted with a battery powers the robot through the ocean, unhindered by propellers (螺旋桨).
During test dives in Fiji's Rainbow Reef, SoFi moved alongside the sea life at depths of 50 feet for up to 40 minutes at a time, taking high-resolution photos and videos. Even more importantly, it was able to do so without causing any disturbance. The researchers say sometimes the fish would swim alongside the strange-looking robo- fish out of curiosity, while at other times they appeared completely unaware of its existence.
While SoFi currently only records videos, future versions will include sensors. "For us, this fish is magical," says Rus. “We imagine someday it might help us uncover more mysteries from the amazing underwater world that we know so little about."
1.Why was SoFi created?
A.To protect fish from being caught.
B.To stop oceans from being polluted.
C.To learn about the underwater world
D.To solve the issues AUVs have found.
2.Which of the following can replace the underlined word “emulates” in Paragraph2?
A.Feeds. B.Catches.
C.Protects. D.Imitates.
3.What is the third paragraph mainly about?
A.The development of AUVs.
B.Working principles of SoFi.
C.How AUVs are used underwater.
D.SoFi's contribution to fish protection.
4.What is the main advantage of SoFi?
A.It will not scare real fish. B.It can record videos.
C.It is equipped with sensors. D.It cannot be seen by real fish.

With climate change and overfishing threatening our oceans, it is becoming increasingly important for researchers to closely observe and check sea animals and plants. However, it’s almost impossible to make it since human presence scares the animals. Now, thanks to the robot, aka SoFi, researchers may be able to solve the problem.
Built by MIT’s laboratory, the snow-white remote-controlled robot simulates fish, complete with a flexible tail that moves from side to side and two “fins (鳍)”.
When the robot is under the sea, a motor is pumping water into a pair of balloon-like rooms located in the robot’s tail. These rooms operate similarly to the key parts in engines. As one room expands, the tail bends to one side; when the motor pushes water to the other channel, the tail bends in the other direction. Thus the robot gains the ability to move to where it wants to go.
SoFi solves many of the issues that have affected the usefulness of previous robots --- some types of autonomous underwater vehicles (AUVs)
AUVs traditionally often have had to be tied to a boat because radio frequency communications do not work well underwater. So researchers use sound waves. The new technology can travel greater distances, allowing drivers, by using a controller, to pilot SoFi from up to 50 feet away. SoFi can move around the ocean, unaffected by ropes. Also limiting traditional AUVs’ usefulness is the risk of hitting something, like hard stones. With the outside made of rubber and plastic that can keep its built-in electronics dry, SoFi can efficiently avoid hitting. So a soft robot is more likely to survive a potential crisis.
During test dives in Rainbow Reef, SoFi swam alongside the unsuspecting ocean life at depths of 50 feet for up to 40 minutes at a time, obtaining high-quality photos and videos. More importantly, it was able to do so without causing any disturbance. Researchers say sometimes the fish would swim alongside the strange-looking robot in curiosity, while at other times they appeared to completely ignore its existence. “It’s not perfect, but we’re improving it. Our efforts will pay off,” says Robert Katzschmann.
1.The robot SoFi is created to ________.
A.observe climate change B.help to monitor sea creatures
C.catch fish and observe them D.prevent overfishing in oceans
2.What does the underlined word “simulates” in Paragraph 2 probably mean?
A.Is modeled after. B.Is designed for.
C.Is combined with. D.Is applied to.
3.What’s Paragraph 3 mainly written to show?
A.The shape of SoFi. B.The application of SoFi.
C.The structure of SoFi’s tail. D.The theory of SoFi’s movement.
4.The materials for SoFi’s outside help SoFi to ________.
A.stay safe underwater B.take high-quality photos
C.stay deeper under the sea D.better attract sea creatures
5.What’s Robert Katzschmann’s attitude towards SoFi?
A.Satisfied. B.Negative. C.Hopeful. D.Neutral.

As China becomes increasingly urbanized (城市化), it has to find space for its urban and
rural citizens as both groups become increasingly integrated. Experts suggest a possible model
way may be “re-inventing” a “garden city”.
China’s mega-cities are bursting at the borders and the country is now undergoing the quickest and biggest urbanization in the history of mankind. It is estimated that by 2025, China will have 400 million more people living in its cities, raising its urban population to 900 million. Besides, new satellite towns are mushrooming on the urban fringes while city ring roads are rippling outwards into the countryside at amazing speed. Satellite maps collected by Professor Joshua Bolchover at the University of Hong Kong bring the problem sharply into focus. They track the changing rural-urban framework in the past 30 years, and suggest that cities are cruelly destroying surrounding rural land and rapidly reducing the amount of arable（可耕种的）land, which gives way to new residential blocks, new industrial zones, new financial centers and the other inevitable signs and signatures of economic growth.
This, however, is not sustainable growth pattern, especially when China has the world’s largest population to feed. So concerned urban planners are starting to note the social and physical effects of diaspora（大移居）when replaced rural communities are forced into the cities.
On the other hand, a trend of thought is gradually taking shape and this is the concept of the “garden city”, a combination of country and city that is being proposed by architects and city planners. Hua Li, from Tao Architects, is among the many professionals with such a voice. His argument is supported by a long-term study on this subject. As Hua says, the answer is to preserve patches of productive farmland within urban boundaries. Less transportation means we have fresh agricultural products at lower costs and less carbon emission in the city. And urban farmland can also be showcased for agricultural tourism and education.
The concept is already practiced at the grassroot level. Agriculture has gone into the air, up to roof and balcony in some communities in the cities. It’s common to see organic “hanging garden” on the roof of some traditional courtyard home. According to some people, the rooftop project translate to tangible (= practical) benefits, such as safe, nutritious vegetables, a cooler home in summer. Some say thanks to the tomatoes they plant that are natural insect killers, there’re fewer mosquitoes. Apart from these, it also contributes to better bonding with neighbors. Zhang, a doctor in Beijing, began creating his hanging garden five years ago. Since his garden became home to 30 kinds of vegetables and fruit --- all enough to feed his family, neighbors have enjoyed dropping by for a relaxing chat or just to see how well the lovely vegetables and fruit are doing.
Although people like Zhang are still rare and the greening of roof space with vegetables and fruit takes skill and energy, with more positive media exposure and advanced technology there is the prospect that garden city will become common practice in the near future. By then, cities will no longer look so gray when seen from the satellites.
1.What is the purpose of paragraph 2?
A. To show the experts’ concern about the increase of population.
B. To persuade people into supporting economic growth in cities.
C. To explain the reasons for the change of rural-urban framework.
D. To inform the readers of the consequences of quick urbanization.
2.In Hua Li’s opinion, a combination of country and city will __________.
A. benefit the environment and lower living costs
B. become a project that needs a long-term study
C. lead to more rural communities being replaced
D. attract more farmers to take tours in cities
3. Zhang is mentioned (Paragraph 5) to show that __________.
A. he achieves his dream to own a hanging garden
B. hanging gardens are becoming more popular
C. the garden contributes to a better neighborhood
D. he is a pioneer to practise the gardening concept
4.As for the concept of the “garden city”, the writer feels_________.
A. desperate B. hopeful C. disappointed D. concerned
