then he would read his paper bythe bright burning 
fire of electric coals.

• Need
Need é um verbo semi-modal, pois, por algumas 
vezes, se comporta como verbo principal e outras, 
como auxiliar.
Como verbo principal o need é conjugado com os 
verbos auxiliares (don’t/doesn’t/ didn’t/ will), ou com 
outros modais.
Ex.: I don’t need a teacher.
(Eu não preciso de um professor.)
do you need a teacher
(Você precisa de um professor.)
He needs to talk to a teacher.
(Ele precisa falar com um professor.)
Na forma negativa indica que não há obrigação ou 
necessidade de fazer algo.
Ex.: You needn’t take off my shoes.
(Você não precisa retirar seus sapatos.)
– Afirmativo
Sentenças afirmativas com o semi-modal Need 
não são muito comuns e são frequentemente usadas 
em um contexto formal.
Há sempre uma palavra negativa na sentença, 
mesmo quando toda a estrutura é afirmativa. (No 
one, nobody, nothing)
Ex.: No one need think that we are doing this 
every week.
(NInguém precisar achar que eles estão fazendo 
isso essa semana)
Nobody need know the name of the person who 
made the complaint.
(Ninguém sabe o nome da pessoa que fez a recla-
mação.)
– Negativo
Como semi-modal, na forma negativa do need 
deve-se acrescentar not.
Não utilizamos verbos auxiliares como don’t/
doesn’t/ didn’t.
Ex.: You needn’t mention this to your mother.
(Você não precisa mencionar isto para sua mãe.)
You need not spend a lot of money on presents.
(Você não precisa gastar todo o seu dinheiro em 
presentes.)
– Interrogativo
A forma interrogativa de Need não é muito uti-
lizada e possui um sentido muito formal. Não será 
adicionado nenhum verbo auxiliar, somente inverterá 
a posição do sujeito da oração e o semi-modal.
Ex.: Need I buy milk?
( Eu preciso comprar leite?)
Need we write this down ?
(Nós precisamos escrever abaixo?)
– Uso:
* Não obrigação
Como dito anteriormente, o semi-modal need é 
mais usado na negativa e indicada que não obrigação 
de algo.
Quando expressamos a obrigação no passado, o 
semi-modal need pode ser utilizado como “didn’t 
need” ou “didn’t have to.
Ex.: We needn’t spend much time on this topic. 
It’s not going to be in the exam.
(Eu não preciso gastar muito tempo com esta ma-
téria. Não cairá na prova)
Cans of soup needn’t be kept in the fridge.

ladeira.)

any food.

Another example of a Navy career is a Navy Hull

12. TEXTO I
‘Brazilian Atlantis’: Scientists discover traces 
of sunken continent under Atlantic Ocean
Granite formed on dry land has been discovered 
beneath the ocean off the coast of Brazil. Scien-
tists suggest that it might be part of a sunken 
continent which disappeared millions of years 
ago and already branded it ‘Brazilian Atlantis’.
A Japanese-manned submersible discovered 
a large mass of granite and a large amount of 
quartz sand 900 miles off the coast of Rio de Ja-
neiro, according to the announcement made by 
The Japan Agency for Marine-Earth Science and 
Technology (JAMSTEC) and the Geology Service 
of Brazil (CPRM).
These materials, normally found on dry land, su-
ggest that a continent once existed in the region 
and then sank. “It is unusual because it is granite 
rock,” CPRM geology director Roberto Ventura San-
tos as quoted by ‘The Telegraph’. “And you don’t find 
granite on the seabed. It is more usual to find it on 
the mainland.”
The granite was discovered in a seabed that was 
estimated to have disappeared under the ocean 
waters tens of millions of years ago.
“South America and Africa used to be a huge, uni-
fied continent. The area in question may have been 
left in water as the continent was separated in line 
with the movements of plates,” said Shinichi Ka-
wakami, a professor at Gifu University, Japan Ti-
mes reports.
The material was reportedly found more than 
8,000 feet beneath the sea in a region known as 
the Rio Grande Elevation.
“This is the region that has been least explored 
worldwide,” added Kawakami. “So, we believe it is 
very important to research it.”
“From an analysis, we began to see that the area could 
be a piece of the continent that disappeared into the 
sea millions of years ago,” Santos said as quoted by 
AFP. “This could be Brazil’s Atlantis. We are almost cer-
tain, but we need to strengthen this hypothesis.”
The fabled island was first mentioned by Greek 
philosopher Plato in his dialogues ‘Timaeus’ and 
‘Critias’, written about 360 BC. According to Plato, 
Atlantis was situated in front of the Pillars of Hercu-
les, the phrase that was applied in Antiquity to the 
promontories that flank the entrance to the Strait 
of Gibraltar. The civilization of Atlantis conquered 
many parts of Western Europe and Africa appro-
ximately 9600 BC. But the continent is believed to 
have sunk during a catastrophic natural disaster.
Scientists plan to drill for more samples later this 
year, as further confirmation is needed. Experts still 
remain cautious about jumping to conclusions.

“may” em “may have been left” (linha 22) indica:
a) permissão.

d) probabilidade.
13. Brazil to replace oil rigs with ‘underwater cit-
ies’
Traditional oil rigs will be replaced with “un-

plans being drawn up by Petrobras, Brazil’s state-
-owned energy group.

A ,Petrobras oil platform at Guabanara bay in Rio 
de Janeiro.
Petrobras plans to turn science fiction into reality 
to extract oil from the vast pre-salt oil fields dis-
covered off the south east coast of Brazil.
The plan is to construct ‘cities’ more than 2,000 
metres under water, containing machines, giant 
pieces of equipment and robots that could ins-
pect the systems being used to extract millions 
of barrels of oil. Many operations would be fully 
automated while others would be controlled by 
humans at a distance.
Petrobras already owns virtual reality laborato-
ries where engineers can inspect 3D images of 
oil fields. But now they want to take a further te-
chnological leap by installing floating rig equip-
ment on the sea bed.
The machinery under the sea would be capable 
of separating oil, gas, water and sand, compres-
sing substances and generating enough energy 
to keep the operation function.
