There are many theories about the beginning of drama in ancient Greece. The one most widely accepted today is based on the ____ that drama evolved from ritual( 宗教仪式). The argument for this view goes as follows. In the beginning, human beings ____ the natural forces of the world -even the seasonal changes-as unpredictable, and they sought through various means to ____ these unknown and feared powers. Those measures which appeared to ____ the desired results were then kept and repeated until they changed into ____ rituals. ____ stories arose which explained or masked the mysteries of the rituals. As times passed, some rituals were ____, but the stories, later called myths, continued to exist and provided material for art and drama.
Those who believed that drama evolved out of ritual also argue that those rituals contained the ____ of theatre because music, dance, masks, and ____ were almost always used. ____, a suitable site had to be provided for performances and _____the entire community did not participate, a(n) ____ division was usually made between the “area of acting” and the “area in which an audience sits”. Besides, there were performers, and, since considerable importance was ____ to avoiding mistakes in the practice of rituals, religious leaders usually ____ that task. Wearing masks and costumes, they often imitated (模仿) other people, animals, or supernatural beings, and mimed (用哑剧表演出) the ____ effect―success in hunt or battle, the coming rain, the revival of the Sun- ____ an actor might. Eventually such dramatic representatives were separated from ____ activities.
Another theory traces the theater’s origin from the human interest in ____. According to this view, tales about the hunt, war or other things are told and gradually spread. ____ through the use of action and dialogue by a narrator and then through the assumption of each of the roles by a different person.

Nowadays people tend to digitalise everything from watches to fridges. It seems you can choose any item labeled as “smart”. 1.. However, there are plenty that can be used to reduce emissions and save money.
If you’re a part of the digitalisation movement，you might be interested in the concept of smart homes. It means that every element of your house can be controlled from a panel on the wall or your phone.2.. Use your mobile to power them on or off，and you may feel truly modern or truly lazy. Aside from the benefits of living a more comfortable life, this presents an opportunity to cut down on your electrical bills.
Electricity generation today represents 31% of total global fossil fuel use and around 40% of all energy-related CO2 emissions.3. It is considered as the first step to prevent global climate change. Connect a smart thermometer to the heating and cooling system and set a specific temperature at which the heating begins to work. Doing so, the room will be at a desired temperature when necessary and switches on a power-saving mode when not occupied. Similarly, by installing a CO2 sensor, you can have an automated ventilation (通风) system.4..
In a 150,000m2 office complex near Munich， called Campeon, energy costs of up to 117,067 Euro were saved after the use of environmental control devices this year. In this way, they are contributing to a large decrease in CO2 emissions. Clearly, smart homes are about much more than just living a comfortable life.5..
A.It is actually about living a green life
B.Smart devices have been installed worldwide nowadays
C.It starts working only when CO2 concentrations reach a certain limit
D.There seem to be an ocean of such so-called “smart” inventions
E.Bearing this in mind, measures should be taken to make buildings more energy-efficient
F.Alternative energy must be discovered before the fossil fuel runs out in the future
G.This includes basics such as heating and lighting and many other appliances
An epidemic is the occurrence of a disease which affects a very large number of people living in an area and which spreads quickly to other people. Like infectious diseases, ideas in the academic world are spreadable. But why some travel far and wide while equally good ones remain in relative insignificance has been a mystery. Now a team of computer scientists has used an epidemiological model to imitate how ideas move from one academic institution to another. The model showed that ideas originating at famous institutions caused bigger “epidemics” than equally good ideas from less well-known places, explains Allison Morgan, a computer scientist at the University of Colorado Boulder and lead author of the new study. “This implies that where an idea is born shapes how far it spreads, holding the quality of the idea constant.” says senior author Aaron Clauset, also at Boulder.
Not only is this unfair --- “it reveals a big weakness in how we’re doing science,” says Simon DeDeo, a professor of social and decision sciences at Carnegie Mellon University, who was not involved in the study. There are many highly trained people with good ideas who do not end up at top institutions. “They are producing good ideas, and we know those ideas are getting lost,” DeDeo says. “Our science, our scholarship, is not as good because of this.”
The Colorado researchers analyzed an existing data set of computer science department hires in North America, as well as a database of publications by these hires. First they looked at how five big ideas in computer science spread to new institutions. They found that hiring a new member accounted for a little more than a third of the time --- and in 81 percent of those cases, transfers took place from higher- to lower-status universities. Then the team imitated the broadcasting of ideas using an infectious disease model and found that the size of an idea “epidemic” (as measured by the number of institutions that published studies on an idea after it originated) depended on the status of the originating institution. The findings were published online last October in EPJ Data Science.
The researchers’ model suggests that there “may be a number of quite good ideas that originate in the middle of the pack, in terms of universities,” Clauset says. DeDeo agrees. There is a lot of good work coming out of less famous places, he says: “You can learn a huge amount from it, and you can learn things that other people don’t know because they’re not even paying attention.”

The Notre Dame fire has been put out, but its spire and a large portion of its wooden roof have been damaged. The terrible destruction causes a sudden sharp pain to people around the world. On Chinese social media network Wechat a common comment on the disaster is: “What a pity that we cannot see the damaged parts of the wonder anymore.”
But the good news is that there is at least one way of seeing them, namely via a video game called Assassin’s Creed: Unity. In this game, the player can travel to one city after another and enter the buildings exactly like what they are in reality, and see Notre Dame as it was before the fire. Further, with virtual reality technology, which is already quite mature, one can even look around the undamaged Notre Dame as if it is still there. Maybe digital technology could help to better protect architectural cultural heritage.
The idea of digitizing ancient buildings, making digital models of them so their data can be saved, dates back to the 1990s and the necessary technology has continued to advance since then. By scanning the ancient buildings with lasers, building 3D models with multiple images, as well as measuring everything precisely, engineers can make a copy as accurate as the real one.
As computers and smartphones are hugely popular, the digital replica has great use value. First, it allows tourists to feel the cultural relics without touching them, which helps protect them. The virtual tour of Dunhuang Grottoes in Gansu Province is a good example of this as tourists can view the paintings without standing near them. Furthermore, it can make the digitized cultural relics more famous by spreading awareness about them via the Internet. In 2000, a virtual tour of the Great Wall became very popular at the Hannover World Expo, which increased the number of foreign tourists visiting the site in the following years. Above all, it preserves all the information of the cultural relics. Even if the original ones are damaged one day, people can still know what they were like and can build a replica if desired.
Of course, however precise a model is, it is not the original. Time is the biggest threat to a country’s architectural heritage, which will always become ruins with the passing of time. Maybe we will have better technologies in the future, but the digital technology offers a practical way to preserve architectural cultural heritage at the moment.

A Wisconsin mom makes mini-me toys as unique as the children who embrace them.
As a social worker using play therapy in the 1990s to help children through their cancer treatment, Amy Jandrisevits wished she could comfort her patients with dolls that bore their all-too-familiar hair loss and surgery scars. “I would clear up Goodwill for bald Cabbage Patch Kids because that was the closest thing I could find. ”she says. “I thought these kids need something that looks like they do. ”The idea stuck with Jandrisevits after she left social work in 2001 to start a family. Then in 2015, a mom whose daughter lost a leg to amputation(截肢) asked Jandrisevits, handy with a sewing machine, if she could craft a mini-me doll for the girl.
After Jandrisevits posted a photo of the legless doll on Facebook, orders poured in for likeness with everything from albinism(白化病) to birthmarks. “Differences make kids feel isolated and judged, ”she says, “with a doll, a child sees I am not the only one who looks this way. . . and beautiful enough to be a doll.” Jandrisevits, 46, has since crafted nearly 400 custom dolls with her New Berlin, Wis, dining room table, with donors often covering the $ 100 cost through Jandrisevits’s nonprofit A Doll Like Me. The mom of three insisted on making each doll herself with help from her mother and a friend.
For Keagan Cameron, 2, whose rare skin condition has him covered in birthmarks, Jandrisevits matched the doll’s spot exactly. “That was the most amazing thing,” says Keagan’s mom, Joy.
Brian Grassi of Coventry, R. I. , says she wept like a baby when a doll came in the mail for his daughter Emma, born three months later in October without her lower left arm. “Seeing my daughter with her doll, it makes me think about her future, not her limitations.”
