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.”
