C.It will deliver lectures and mobile clinic services in schools.D.It will build a better service model for special children.31.Where is the text most likely from?A.A diary.B.A magazine.C.A science fiction.D.A guidebook.D"The world's first 35 kilovolt superconducting power cable was put into operation in Shanghai orWednesday,making China among the global leaders in superconducting transmission applications'said its operator,the Shanghai branch of State Grid Corp of China.The high-capacity superconducting power line,which is so far the world's longestsuperconducting cable transmission project with the largest transmission capacity,marks a majorbreakthrough in core technologies of China's construction of a new power system,according toState Grid Shanghai Municipal Electrical Power Co.Installed in the commercial area of Xuhui district,the 1.2-kilometer cable connects two 220 kVsubstations with a designed current capacity of 2,200 amps.This is also the first superconductingtransmission project built by the centrally administered State Grid in the country.According to State Grid Corp of China,the nation's largest power provider by generatingcapacity,the superconducting cables-one of the most revolutionary cutting-edge technologies inthe power sector-represent an innovative power transfer technology that has the potential to offernumerous benefits.According to Xie Wei,chief engineer at State Grid Shanghai Municipal Electrical Power Co,thetransmission capacity of superconducting cables is much greater than that for conventional cables,but with much less transmission loss.It is also very suitable for power supply in high-load densityareas,providing a new solution to the problem of power supply in high-load-density areas ofmegacities(特大城市)."One 35 kV superconducting cable transmission line can transmit the same amount of power asa traditional 220 kV power line and saves 70 percent of underground pipe gallery space,"Xie said."The transmission efficiency of the high-capacity superconducting power lines can provide reliableand stable power to megacity urban centers,"he added.Gan Zizhao,an academician from the Chinese Academy of Engineering,said,"superconductingcables have always been an important way to solve issues of power supply to superlarge cities amidefforts to push forward power upgrade and transformation in the country."With a temperature of-196C,which is the temperature range required for liquid nitrogenliquefaction,the technology can greatly improve losses in power transmission due to a resistance ofzero,said the company.The low-temperature superconducting cable project is one of the resultsof the strategic cooperation between State Grid and the Shanghai Municipal Government in the fieldsof science and technology.32.What can we know of the power line?A.It made China the leader of the world in the new power system.
