2)Match the definitions about Electricity:
1.Renewable energy source 3.Secondary
2.Nonrenewable energy. 4.Energy carrier
a) ( )A kind of energy produced by converting primary sources of energy.
b) ( )A kind of energy that can be converted to other forms of energy.
c) ( )An energy source that takes millions of years to form.
d) ( )Energy from sources that are naturally replenishing but flow-limited.
3)Argumentation:Exercício adaptado da pág 38.Completar as frases,nas letras tem o começo da frase e nos parênteses coloque a letra correspondente a terminação da frase.
a)The electricity that we use is a secondary energy source
b)Electricity is also referred to as an energy carrier,
c)Primary energy sources are renewable or nonrenewable energy,
( ) but the electricity we use is neither renewable nor nonrenewable.
( ) wich means it can be converted to other forms of energy such as mechanical energy or heat.
( ) because it is produced by converting primary sources of energy such as coal,natural gas,nuclear energy,solar energy,and wind energy,into electrical power.
Soluções para a tarefa
1)Write in the sentences about Electricity are T(true) or F (false) :
a)(T)Electricity is the flow of electrical power or charge.
Alternativa verdadeira: a eletricidade e um fluxo de força eletrica ou carga, mais especificamente, de eletrons.
b)(F)Electricity is not a basic part of nature.
Alternativa falsa: eletricidade e uma parte basica da natureza, existindo por exemplo nas descargas eletricas da atmosfera.
c)(F)Electricity the least used forms of energy.
Alternativa falsa: a eletricidade, ou energia eletrica e uma das formas mais utilizadas de energia.
2)Match the definitions about Electricity:
a) (3)A kind of energy produced by converting primary sources of energy.
b) (4)A kind of energy that can be converted to other forms of energy.
c) (2)An energy source that takes millions of years to form.
d) (1)Energy from sources that are naturally replenishing but flow-limited.
Realizando a traducao, temos:
1. Fonte de energia renovável
3. Secundário
2. Energia não renovável.
4. Transportadora de energia
a) (3)Um tipo de energia produzida pela conversão de fontes primárias de energia.
b) (4)Um tipo de energia que pode ser convertida em outras formas de energia.
c) (2)Uma fonte de energia que leva milhões de anos para se formar.

3)Completar as frases,nas letras tem o começo da frase e nos parênteses coloque a letra correspondente a terminação da frase.
a)The electricity that we use is a secondary energy source
b)Electricity is also referred to as an energy carrier,
c)Primary energy sources are renewable or nonrenewable energy,
(c) but the electricity we use is neither renewable nor nonrenewable.
(b) which means it can be converted to other forms of energy such as mechanical energy or heat.
(a) because it is produced by converting primary sources of energy such as coal, natural gas, nuclear energy, solar energy and wind energy, into electrical power.
O que deixa as frases assim:
a)The electricity that we use is a secondary energy source because it is produced by converting primary sources of energy such as coal, natural gas, nuclear energy, solar energy and wind energy, into electrical power.
b)Electricity is also referred to as an energy carrier, which means it can be converted to other forms of energy such as mechanical energy or heat.
c)Primary energy sources are renewable or nonrenewable energy but the electricity we use is neither renewable nor nonrenewable.
Realizando sua traducao, temos:
a) A eletricidade que usamos é uma fonte de energia secundária, porque é produzida pela conversão de fontes primárias de energia, como carvão, gás natural, energia nuclear, energia solar e energia eólica, em energia elétrica.
b) A eletricidade também é chamada transportadora de energia, o que significa que pode ser convertida em outras formas de energia, como energia mecânica ou calor.
c) As fontes de energia primária são renováveis ou não renováveis, mas a eletricidade que usamos não é renovável nem não renovável.
