To find its own spot,the system uses a sensor suite similar to ones found in many luxury cars.This includes a motion sensor that scans for moving cars and pedestrians,and a forward-facing laser rangefinder normally found in adaptive cruise control to determine the distance of objects in front of the car.Information from these sensors is then fed to an onboard computer to plot the vehicle’s course.The user can watch the whole process from their phone.
Better still,it will be affordable.The team has spent the last year moving from high-end imaging and processing equipment to less expensive components.In experiments,the vehicle was able to navigate through a crowded parking structre,find an empty spot,and park all on its own.And the greatest appeal of the Virtual Valet Parking App is that it requires no change to existing parking facilities or infrastructure.
For the moment,the only car equipped for control by Virtual Valet is Carnegie Mellon’s modified(改进)Jeep Wranger, which the researchers have named NavLab11.But Steinfeld hopes that major car manufacturers will adopt the technology.
It might be more than technology that holds up the show,however.Self-driving cars have been licensed in only three US states—California,Nevada and Florida—and it’s unclear how this app would agree with self-driving laws.Until these questions are settled,your insurance provider might be unwilling to cover a ding (凹痕)from a parking incident. 71.It can be learned from the first two paragraphs that . A.parking lots are too crowded B.parking spaces are too limited
C.your car can park automatically via a smartphone app

A.How to determine the distance of objects. B.How the Virtual Valet App works. C.How to use the spstem.
D.How to analyze the information about the vehicle’s course.
73.The underlined word“plot”in Paragraph 3 probably means“ ”. A.draw B.circle C.change D.follow
74.What is the biggest advantage of the system according to the text? A.It is very cheay.
B.It can help your car park wherever you want. C.It is very convenient to use.
D.It can adapt to the present parking facilities. 75.We can infer from the text that . A.no car manufacturers show interest in the technology B.there will be come difficulty in promoting the technology C.the technology is now widey used in the US

[1]For the people living in the Nile Basin,the river is their life.This 6, 825 km river,whose watershed(流域)covers three million square kilometers,flows through mountains,woodlands,lakes and deserts.Its potential for fishing,tourism and shipping is great—but so are its challenges.
[2]Water shortage is a problem.It is serious in Egypt and Sudan and will soon influence several other countries in the watershed,too. Today,about 160 million people depend on the Nile River for their living.Within the next 25 years,the district’s population is expected to double,adding to the demand brought about by growth in industry and agriculture.The frequent drought adds to the urgency.
[3]Water quality is also a problem.Precious soil is washed out to sea.Wastes from industry and agriculture .Higher concentrations of salt influence irrigated soils.Water-borne diseases continue unchecked.In areas where it’s hot and damp,water plants choke off lakes,dams and other sections of the river,making it difficult for fishing and other businesses to move forward.
[4]Native people along the narrow area of farmland have watched the sand move closer day by day.They’ve seen the river change course,and their only source of water thickened with mud.They’re very poor and have few choices.
[5]But a mew program,the Nile Basin Initiative,is offering very practical assistance.The program is more than a water-management project.It’s also a plan for the social and economic development of a vast district:it concentrates on the needs of the poorest of the poor and the environment that supports them.
[6]These are whole ecosystem(生态)problems,calling for united solutions.Half the Nile Basin’s countries are among the world’s poorest nations;yet,somehow,they must find the resources,skills and political will to overcome these challenges.
76.What does the underlined word“its”(Line 3,paragraph 1)refer to?(no more than 3 words) 77.What is the main idea of the second and the third paragraphs?(no more than 15 words)
78.Fill in the blanks in Paragraph 3 with proper words.(no more than 5 words)
