Prática de Shadowing: Reading Explorer Foundation, Unit-11 Ichthyosaurs - Aprenda a falar inglês com vídeo
Criando lição...
1
While dinosaurs walked the Earth,
2
sea monsters called ichthyosaurs ruled the world's oceans.
3
Icthyosaurs were ancient reptiles.
4
They first appeared about 251 million years ago,
5
during the Triassic period, about 20 million years before dinosaurs came about.
6
True to their name, which means fish lizards in Greek, the earliest ichthyosaurs looked much like lizards with fins.
7
Over a period of 100 million years, their bodies changed and they developed fish-like tails.
8
They had long, narrow skulls and jaws with sharp teeth.
9
These teeth were used to catch and eat animals like fish and squid.
10
Their eyes were the largest ever recorded of any animal.
11
In fact, one species, Temnodontosaurus, had eyes that were over 10 inches wide.
12
Large eyes helped ichthyosaurs see through the dark waters of the deep ocean.
13
Icthyosaurs were different sizes.
14
Some were only around 60 centimeters long, but the longest were about 26 meters long.
15
Icthyosaurs had paddle-like fins and a large tail,
16
which helped them swim at speeds of around 35 kilometers per hour.
17
Altogether, these qualities put ichthyosaurs at the top of the food chain.
18
By the late Cretaceous period,
19
about 25 million years before an asteroid wiped out the dinosaurs, ichthyosaurs became extinct.
20
Some scientists believe it may have been a result of climate change.
21
But the exact reason why these early sea monsters died out is still a mystery.

O que é a Técnica de Shadowing?
Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
