1、You should spend about 20 minutes on this task.The two graphs show the main sources of energy in the USA in the 1980s and the 1990s.Write a report for a university lecturer describing the changes which occurred.Write at least 150 words.model answer:The two graphs show that oil was ...
Fat is a concentrated source of energy. 脂肪是能量的主要来源, It can be divided into two main groups—saturatedand unsaturated. 它有饱和与不饱和两大类。 Saturated fat is generally solid at room temperatureand is usually from animal sources. ...
Protica是任命制造的一个Sunkist,因此, 2013年它是我们的一个主要被集中的帐户设法完成。 [translate] aElectrical energy sources can be broken down into two broad categories, thermal and non-thermal. A brief discussion of varying alternatives follows below. 正在翻译,请等待... [translate] ...
Fat is a concentrated source of energy. 脂肪是能量的主要来源, It can be divided into two main groups—saturated and unsaturated. 它有饱和与不饱和两大类。 Saturated fat is generally solid at room temperature and is usually from animal sources. 饱和脂肪在常温下是固体,通常来源于动物。 It's fou...
MALE PROFESSOR: Alright folks, let's continue our discussion of alternative energy sources, and move on to what's probably the most well-known alternative energy source, umm, solar energy.The Sun basically provides Earth with a virtually unlimited source of energy every day, but the problem has...
between traditional and non-traditional energy sources. A traditional energy source is one which is at present widely exploited. It will be realized, broadly, that the traditional sources are the non-renewable ones. This is not entirely true, however, as a good deal of oil is locked up in ...
The exploitation of both conventional and unconventional hydrocarbons may lead to still not well-known environmental consequences such as ground deformation and induced/triggered seismicity. Identifying and characterizing these effects is fundamental for
