Scientists test WiTricity – Wireless Electricity A team of US researchers has come up with an electricity system that does not need wires. This is a
breakthrough in what will hopefully be a wireless future. The scientists, from the Massachusetts
Institute of Technology, lit a 60-watt light bulb using magnetic fields. In the test, the power source
was just two metres away from the light, but the team hopes they will soon be able to send electricity
longer distances through the air. They have dubbed their new invention “WiTricity”, or wireless
electricity. Although wi-fi has been around for some years now, it has been limited to the
transmission of information, especially between computers and modems, printers and scanners. This
is the first time electrical appliances have been powered wirelessly.
This new development means that our houses may be free from tangled wires. Gone will be the days
of having to unplug the vacuum to go from room to room, and of having countless plugs hidden
behind the TV and stereo. The new source of delivering power to gadgets remotely may also reduce
the number of fires caused by poor wiring and overloaded sockets. It turns out the concept is not so
new. A century ago, inventor Nikola Tesla struck upon the idea of building a huge tower in New
York that would wirelessly beam power to the city. Unfortunately, his idea never came to fruition,
until today, that is. It will still be a while before we have wireless homes and offices. Safety experts
will be checking closely to ensure the power source causes us no harm.

USE OF ENGLISH
1- SIMPLE PRESENT
Afirmativas:
Nas terceira pessoa do singular, há a necessidade de adicionar ao fim do verbo as extensões “s“, “es” ou
“ies“.Para as demais pessoas, o verbo fica igual à forma infinitiva (mas sem a partícula “to”).
Examples:

This new development means that our houses may be free from tangled wires.

Interrogativas:
Para fazer frases interrogativas, vamos usar o auxiliar DO (ou DOES, para a terceira pessoa do
singular) antes do verbo.

Negativas:
Para tornar uma frase negativa, é só adicionar o “NOT” depois do DO ou DOES:
Examples:
