Posting a photo of the food you're about to eat on WeChat has become a daily ritual(惯例;仪式) for many.Often this food in the photo isn't as appealing to those looking at it,but scientists are now claiming taking a photo of your food before you eat it makes it taste better.
Researchers at University of Minnesota's Carlson School of Management claim taking a photo puts you in the moment and in doing so,heightens your (41)I.The person taking the photo will,on some level,feel the motivation to continue the practice.
Researchers wondered about the power of rituals after noticing the funny (42)K that people often perform before eating and drinking.They conducted experiments to investigate whether these kinds of habitual behaviour influences taste.
In the first experiment,some participants were asked to eat a piece of chocolate following a detailed set of (43)A:‘Without unwrapping the chocolate bar,break it in half.Unwrap half of the bar and eat it.Then,unwrap the other half and eat it.'The other participants were (44)E instructed to relax for a short amount of time and then eat the chocolate bar however they wanted.
The results showed that those who had performed the ritual rated the chocolate more (45)C,enjoyed it more,and were willing to pay more for the chocolate than the other group.
A second experiment (46)H these findings,showing that (47)B movements don't produce a more enjoyable eating experience.The data also (48)D that a longer delay between ritual and consumption enhanced these effects,even with a common food like carrots.
While these rituals may seem insignificant,the researchers note that the effects they produce are quite amazing.And while rituals are (49)J before mealtimes,they could play a role in other (50)G,too.

5.We all have been told since we were kids that we need at least 8hours of sleep every night.(36)G.Not many.
Sleep,though,is one of the most important things our bodies need to stay to healthy.Without the rest that sleep provides,our bodies and minds wear down to the point where not only do we lose our work efficiency,but lack of sleep can even make us sick.(37)A.
A lot of people eat late into the night and then try to sleep on a full stomach.(38)F
While you're trying to sleep,your body is working hard to absorb whatever you've eaten.Stay away from food a few hours before you go to bed,so that your body can rest.
If you need more hours in the day to get your work done,try to make a chice between waking up extra early and then going to bed on time,or staying up later but then also getting up later.Some people do better and are more productive when they stay up late.(39)DDo some tests on yourself to see which option works better on you.
(40)C.You body and your mind are more efficient when a routine has been set and a habit has been formed.Followed the same positive sleep patterns for a week or a week or a month and you'll notice a big change in how much more restful you feel.

A.If you are struggling to get the sleep you need,here are some suggestions for you.
B.So it's vital to have enough sleep for us.
C.Turn sleep into a habit.
D.Others feel better and have more energy when they wake up early.
E.The more hours we sleep,the more energy we will have.
F.This will not provide yiu with a restful sleep.
G.However,how many of us actually get that many hours of sleep?
