Which day of the week is the happiest? Which is the most depressing? In order to find (25) ________ answers, some experts studied 22,000 people over two months. The data was collected  by (26) ___________(send) messages to their mobile phones twice a day, asking them(27)________ they felt, (28)________ they were with, where they were, and what they were doing.

According to the study, our moods are at their brightest on Saturday and will continue into Sunday. But as the working week (29)______ (begin) on Monday, it is on Tuesday (30) ______ we reach our (31) ______ (low), with levels of contentment(满足) dropping.

“(32)_______ seems that on Monday the weekend has not quite worn off,” said Professor George MacKerron, who led the research. “By Tuesday people are well into the working week and the following weekend is not yet in sight.”

Sit up straight. Say please and thank you. Don’t put your elbows on the table. Most of us were drilled from an early age in proper manners and etiquette. But manners and etiquette (33) _______ vary widely in different cultures.

Take table manners for example. In many parts of the world, it’s considered rude to make noises when eating. The Japanese, however, think it customary to make some slurping(啧啧的) noises while eating noodles. They say the noodles taste better. A person who eats noodles (34) _________ making any sound could seem strange in Japan.

Another interesting cultural difference is portrayed in a TV advertisement (35) _______(set) in an Asian city. It shows an Asian family inviting a westerner to dinner. The Asians prepare a lot of food to show the guest (36)_______ are hospitable(殷勤好客的). Westerners are taught to “clean their plates” and think it’s impolite to leave food in the dishes. So the guest tries to finish his meal without leaving (37)_____ on his dishes. However, an Asian host sees an empty dish as a sign (38)______ the guest wants more food. In the ad, the host immediately prepares more food for the guest, who tries to finish his food again just to show his manners. It becomes a circle of misunderstanding.

Differences are also seen in other aspects. While extending a hand to shake the hand of a person you’re meeting with (39)________(seem) to most of us a universal way of showing friendliness, an Orthodox Jew (东正犹太教徒) will not shake hands with someone of the opposite sex. Similarly, a strict Muslim woman will not shake hands with a man, though a Muslim man will shake hands with a non-Muslim woman. People in these cultures generally avoid (40) _________(touch) people of the opposite sex who are not family members.

 People who wear headphones might want to throw them away while walking outside. A study finds that accidents involving walkers   41   the devices have increased three times in recent years.

Researchers searched the National Injury Surveillance System, the U.S. Consumer Product Safety Commission, Google News archives and Westlaw Campus Research, and they found 116 cases of death or injury   42__ walkers with headphones. Cases in which people were using mobile phones (including hands-free devices) were not included.

Over the years the number of cases increased, from 16 in 2004 and 2005 to 47 in 2010 and 2011. The victims’ average age was 21, and most (68 %) were male. The  43   ( 67% )  were under the age of 30. Most (55 %) were hit by trains, and 70 percent of the crashes, most of which were in urban areas, were   44  .

In 74 percent of the cases, police or eyewitness reports said the walker had headphones on when hit. And 29 percent of reports made mention of horns or warning bells going off before the crash.

The study authors pointed to two likely causes that may be a factor in what they call “the possible   45   between headphone use and walker injury”: sensory deprivation（感官剥夺） and   46  . The latter is more   47   called “inattentional blindness,” referring to the use of electronic devices and how they decrease attention to things going on around us.

Hearing what’s going on in the environment, they point out, could be more important than   48   clues for walkers. But the authors add that this study doesn’t show cause or relationship of headphone use and walker risk, and other factors could have been involved in the accidents, such as walkers being intoxicated（陶醉）or drivers being at fault.

More comprehensive information on such accidents is   49  , the researchers said, to see which groups of people may be most at risk.
