from prosopagnosia, or “face blindness,” a condition that prevents people from recognizing individuals they have met. To use this app, a person first acquires an image of someone’s face, from either the smartphone’s camera or a photograph, and then tags it with a name. When the camera spots that same face in real life, the previously entered information is displayed. The collected data are stored only on a user’s phone, according to the team behind the app. 1. SocialRecall is used to ________.
A. take photos B. identify people C. organize events D. make friends 2. Paragraph 3 is mainly about ________.
A. how the app works B. how the app was created
C. what makes the app popular D. what people can do with the app 3. SocialRecall helps people with prosopagnosia by ________. A. giving names to the photos kept in their smartphones B. collecting information previously entered in the phone C. providing the information of a person when they first meet D. showing the person’s information when it spots a stored face 4. What can we learn about SocialRecall from the passage?
A. It may put people’s privacy at risk. B. It has caused unintended consequences. C. It can prevent some communication disorders. D. It is praised by users for its protective measures.
4、The Leaning Tower of Pisa(比萨斜塔) has never stood straight. The building’s lean has puzzled engineers for hundreds of years. Engineers began building the hell tower in Italy in 1173. It took more than 200 years to finish. It was built on unexpectedly soft ground and the tower began to lean before it was done. The mistake has made the building one of the world’s strange sights.
How can something so unstable last for hundreds of years? The tower has survived two world wars, millions of visitors, and four strong earthquakes. Engineering Professor George Mylonakis wanted to know why. He studied the ground beneath the building and looked at how soil affects the building and how well it stands up.

Mylonakis and other engineers came up with an answer about the tower. The answer has to do with the soft ground under the tower. The engineers found other important reasons, too. The tower is very tall and is made of stone that makes it stiff. Its height and firniness combined with the softness of the foundation soil cause the vibrational(振动的) characteristics of the structure lo be improved considerably in such a way that the tower does not resonate(共振) with earthquake ground motion. So during an earthquake, the tower does not shake as much as the earth under it.
Still, Mylonakis said the tower had almost fallen since it continued to lean more as the soft ground settled under it. In the early 1990s, it was in real danger of falling and the Italian government closed the tower to visitors and started to save it. Crews gradually began to take out small amounts of soil from the high north side. With less soil under it, that side of the tower sank slightly. Engineers also fixed equipment that allows them to make adjustments to the water pressure beneath the tower, further controlling how much the tower leans.
The building still leans. It just leans a bit less than before. Most importantly, the tower is no longer in danger. JohnBurland worked on the project to save the tower. He said it is highly unlikely that the soft ground under the tower will cause it to fall and only a very large earthquake would knock down the tower. 1.Why did George Mylonakis study the leaning Tower of Pisa? A.To find out why it leans. B.To explore why it still stands. C.To call on people to save it. D.To research the soft ground under it.
2.What does the underlined word \A.Shaky. B.Sinking. C.Solid. D.Splendid.
3.What measure was taken to save the tower in the early 1990s?
6
A.Limit the number of visitors. B.Remove soil from two sides. C.Monitor the amount of soil water. D.Make the tower lower in the north.
4.What do John Burland's words suggest in the last paragraph? A.The tower is safe in most cases. B.The tower still leans in danger.
C.The tower may fall due to the soft ground.
D.The tower will stand even if large earthquakes hit.
5、The United States will have more adults aged 65 and over than children by the year 2035, the U. S. Census Bureau says. The agency provides information about the U. S. population that as the American population ages, the demand for services and care for older adults is growing.
SenCura is a company that provides non-medical at-home care for seniors in the northern Virginia area. Its services include help with bathing, transportation, getting dressed and planning and preparing meals. Hollie is one of SenCura's professional caregivers. She visits 88-year-old Olga Robertson's home every day for three hours. Robertson says she likes having Hollie’s help.
But when Hollie is not around, Robertson still has a versatile caregiver—a robot named Rudy. She can have a conversation with him and he's somebody to talk to and can respond. Rudy also tells jokes, plays games and dances with Robertson. In addition to keeping Robertson mentally and physically active, Rudy provides contact with emergency services 24 hours a day. He looks for lost items, reminds Robertson about her doctor's appointments and tells her when it is time to take her medicine. Anthony Nunez is the founder of INF\Robotics, a new company that creates Kudy. He says the idea for the robotic caregiver was inspired by what his own mother lived through when his grandmother got older. \I grew older, I realized we weren't the only family facing this problem. So what I wanted to do was design a robot that's easy to use, designed specifically for seniors, but also affordable,'' he said.

Rudy is not competition for human caregivers. He is there to help but cannot do all the things that caregivers do, like bathe and dress seniors. The robot Rudy adds to what in-home caregivers do for the growing population of seniors. 1.What can we learn about the information provided by the U. S. Census Bureau? A.The number of children will become larger. B.Adults will have to look after more children. C.There will be more seniors in need of services. D.The demand for caregivers will decrease.
2.What does the underlined word \A.Easy-going. B.Multi-functional. C.Considerate. D.Flexible.
3.What can we infer about the robot Rudy? A.He will replace the caregivers. B.He is able to dress the seniors. C.He offers the seniors health care. D.He can help do additional work. 4.What is the main idea of the text? A.America is facing population problems. B.Caregivers are challenged by robots. C.A new company puts robots in seniors' homes. D.Seniors will get better sendees from caregive
6、NASA has a new job listing, and it’s no joke. The US space agency is looking for a “joker” to join their planned mission to Mars.
A mission to Mars is no laughing matter. On average, the red planet is 140 million miles (225 million kilometers) away from Earth. A trip there would take around eight months in a small spacecraft. And Mars has a communications delay of 20 minutes. This means that astronauts will have to wait 20 minutes for a reply, when an emergency happens.
