10、pping gas. Cows are known to produce high levels of methane when they eat and process food.Researchers at the Autonomous University of the State of Mexico are studying how a cows diet affects the production of methane. The researchers are using a specially designed machine to measure the effect. The
11、 scientists use the machine to try to capture the animals breathing to examine the methane released.Most of the gas is released when cows belch. The digestive bacteria in a cows stomach causes the animal to send out the gas through its mouth. There are an estimated 1.3 to 1.5 billion cows in the wor
12、ld. Each animal releases as much as 120 kilograms of methane per year. The U.S. Environmental Protection Agency reports that, whenever measured in pounds, the effect of methane on climate change is more than 25 times greater than carbon dioxide over a 100-year period.As it is difficult to capture th
13、e gas released by cows for use as energy, one way to lessen its release is to change their diet. Scientists in some countries are looking for ways to decrease cow methane.

17、gn language. One of the common ones is that they dont have a gift for language learning. The excuse that one has no talent for learning a certain skill is a tragedy in itself, and this common excuse has possibly discouraged millions of people from accomplishing great things.Many experts and scholars
18、, such as K. Ander Ericsson, one of the worlds leading theoretical(理论的) and experimental researchers, have proposed the theory that skill is mostly a matter of large amounts of deliberate practice. Books such as The Talent Code have helped popularize it. While I do not personally believe that we all

To be specific, anything can be learned, unless of course, you start with the belief that you are not talented.The tr
20、uth is that if you think you are not talented in languages, it probably has something to do with your track record in language classes at school.
