【推荐1】We all know the hard work that filmmakers and actors put in to provide us with entertainment.     1    .

For decades now, film studios have used so-called test screenings to get feedback from members of the public before a movie comes out. Test audience members are usually asked to fill in a questionnaire after a screening, telling the film studio what they liked and didn’t like.    2    , that’s, to measure test audiences’ reactions by using special cameras placed inside cinemas.

Pairing the cameras with custom software, the company can track what each audience member is feeling at any point in the movie, from anger to joy.    3    . The cameras can see in the dark, and the software can figure out a person’s mood based on the slightest of facial expressions. It’s hoped that this new method will allow more detailed feedback from test audiences, because it can accurately read their reactions in real-time.

Test screenings are highly valued in the movie industry.    4    .Viewers of E.T., the Extra-Terrestrial (1982), would have left the cinema feeling a lot different if it weren’t for its test audience’s feedback. “In one cut of the film that was tested, E. T. died instead of going home in his spaceship. You won’t be surprised to hear that the test audience in question didn’t warm to this ending at all.” wrote media website Den of Geek.

    5    , the cameras won’t be installed in public cinemas. After all,unless you’re part of a test audience, being in front of the cameras is best left to the movie stars.

A．In reality, not all of the people are content with the test screenings

B．This works by mapping 68 different points on each audience member’s face

C．And several well-known movies have been greatly changed following feedback

D．The special cameras in public cinemas easily go wrong and often fail to work

E．But for those who are concerned about privacy

F．But it seems that even moviegoers like us have a big impact on how a movie turns out too

G．However, media giant Disney has come up with a more high-tech solution

【推荐3】The world’s top automakers are increasingly offering more electric vehicle models. This growth is expected to continue， with more people choosing to hit the road with clean-running electric- powered cars.

Environmentalists have praised the automakers for taking major steps to limit harmful pollutants linked to worldwide climate change. But electric vehicles are also known for not producing another kind of pollution—noise. They run on batteries instead of fuel， and can operate in silence.

While many people might consider this a good thing， quiet cars can also cause problems. The main danger is that people walking in areas around electric vehicles face a greater risk of being hit if they cannot hear the cars coming.

Governments in the United States and Europe have recognized this problem. So， they have set requirements for manufacturers to add warning sounds to vehicles operating on electricity.

The U.S.Department of Transportation finalized its rules a year ago. The rules require electric and hybrid (混合能源) vehicles to be equipped with some kind of warning sound when moving at speeds up to 30 kilometers per hour. The rules are aimed at preventing injuries among people walking or riding bicycles and to protect the blind.

So what kinds of sounds can we expect to hear from the next generation of electric vehicles? One of the easiest solutions would be for carmakers to simply reproduce the sound a car would make if it actually did run on fuel. But many industry officials believe this would be a mistake.They say this would not support the electric vehicle’s true identity. It would also limit great possibilities to link the car’s sound to a whole new image, which could help increase sales.

Frank Welsch is head of technical development at Germany’s Volkswagen. He said that finding the perfect sound mix is not an easy process. “The electric vehicle sound is its identity,” he said. “It cannot be too annoying. It cannot sound like anything we had in the past.”

An official from Mercedes-Benz said the sound was designed to provide a safe warning without annoying passengers inside the vehicle. He said the goal was to create a car that remains completely quiet on the inside, but fills the sound requirements and supports the model’s image on the outside.

It might seem strange to think that part of our automotive future is currently being developed in the same kinds of recording studios used by musicians. But that is exactly what is happening.
