If a little humanlike robot begged you not to shut it off, would you show sympathy?

In an experiment     1     (intend) to find out how people treat robots when they act like humans, many participants struggled to power down a begging robot named Nao.     2     experiment was conducted by researchers in Germany, whose findings     3     (publish) in the scientific journal PLOSOne.

Nao,     4     was designed to beg about half of the participants not to switch it off but not the other half, was used     5     (measure) if his begging affected how people reacted.

In one previous experiment, researchers found that people preferred communicating with robots with complementary (互补的) personality characteristics to     6     (they) own. And since robots can exhibit social characteristics either     7     (speak) with human voices or taking the shape of a human body, the research suggests that people tend to react “    8     (especial) social to them.”

The researchers said a possible     9     (explain) for their results was that people regarded Nao’s begging     10     “a sign of making its own decision.”

Water on the Moon

NASA has confirmed the presence of water on the moon’s sunlit surface, a breakthrough     1     (suggest) the chemical compound that is vital to life on Earth could be distributed across more parts of the lunar surface than the ice that     2     (find) previously in dark and cold areas.

“We don’t know yet if we can use it as a resource,” NASA Administrator Jim Bridenstine said, but he added that learning more about the water is still crucial.

The discovery comes from the space agency’s Stratospheric Observatory for Infrared Astronomy, or SOFIA — a     3     (modify) Boeing 747 that     4     take telescope high into Earth’s atmosphere,     5     researchers may peer at objects in space with hardly any visual disturbance from water vapor. To detect the molecules, SOFIA also used a special camera to distinguish between water’s specific wavelength of 6.1 microns and that of its close chemical relative hydroxyl, or OH.

The data confirm     6     experts have suspected, that water might exist on the moon’s sunny surface, though the form of it shall be     7     (obvious) to detect. Experts will now try to figure out exactly how the water came to form and why it persists.

“Data from this location reveal water in concentration of 100 to 412 parts per million trapped     8     a cubic meter of soil.” NASA said in a release about the discovery.

“    9     without a thick atmosphere, water on the sunlit lunar surface should just be lost to space,” said Casey Honniball, the lead author of a study about the discovery. “Somehow we’re actually seeing it.”

There are several possible explanations for the water’s presence, including an interesting yet reasonable    10     claiming its origin to the stony micro objects from space. Small balls of glass from that process could trap water, according to the researchers’ paper.

It doesn’t take long to believe our own lies, according to a new study.

Last year at Brandeis University, 42 participants, about half seniors and half millennials(千禧一代), were given a form with 102 questions about     1     they did the previous day. The form asked them to respond     2     questions such as “Did you set your alarm clock?” and “Did you use a fork to eat lunch?”On half the questions,     3     (choose) at random, the researchers told the participants to lie. Forty-five minutes later, the respondents answered     4     same questionnaire. This time, researchers told them to answer all the questions     5       (truthful).

The central research question was: When the participants lied on a question the first time, did they then remember they     6     (lie)?

The results showed that the older group were significantly more likely than the younger     7     (accept) as the truth a lie they had told less than an hour     8     (early).

“Older adults have more     9     (difficult) distinguishing between what’s real and not real” said Laura Paige,     10       was the lead author of the study, “Once they believe a lie, it will create a new memory for something that didn’t happen.”
