Creando lección...
1
Unit 4.
2
A life beyond Earth?
3
A. Is there intelligent life on other planets besides Earth?
4
For years, scientists weren't sure.
5
Today, this is changing.
6
Seth Shostak and Alexandra Barnett are astronomers.
7
They believe intelligent life exists elsewhere in the universe.
8
They also think we will soon contact these beings.
9
B. Why do these astronomers think intelligent life exists on other planets?
10
The first reason is time.
11
Scientists believe the universe is about 12 billion years old.
12
According to Shostak and Barnett, this is too long a period for only one planet in the whole universe to develop intelligent life.
13
The second reason is size.
14
The universe is huge.
15
Tools such as the Hubble telescope have shown that there are at least 100 billion galaxies, says Shostak.
16
and our galaxy, the Milky Way, has at least 100 billion stars.
17
Some planets that circle these stars might be similar to Earth.
18
Looking for intelligent life.
19
See, until recently, it was difficult to search for signs of intelligent life in the universe,
20
but now powerful telescopes allow scientists to identify many more small planets in other solar systems.
21
If these planets are similar to Earth and are close enough to a star, they might have intelligent life.
22
Making contact D have beings from outer space already visited Earth?
23
Probably not, says Shostak.
24
The distance between planets is too great.
25
Despite this, intelligent beings might eventually contact us using other methods such as radio signals or flashes of light.
26
In fact, they could be trying to communicate with us now, but we may not have the right tools to receive their messages.
27
This is changing, however, says Shostak.
28
He predicts that we will make contact with other life forms in our universe within the next 20 years.

¿Qué es la Técnica de Shadowing?
Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
