It is important to read the vocabulary before you watch the video. This will improve your ability to understand the video. It will also help you understand how the new vocabulary is used naturally.
The first time you watch the video, just try to understand the overall situation.
First try to answer all the questions from memory. Then rewatch the video and try to answer the questions that you missed.
Watch the video again while you read the script. Reading and listening at the same time will help you hear each individual word and improve your listening accuracy.
There are several different activities that focus on test preparation, vocabulary, grammar, and sentence structure.
Es importante leer el vocabulario antes de ver el video. Esto mejorará su capacidad para comprender el video. También le ayudará a comprender cómo se usa el nuevo vocabulario de forma natural.
La primera vez que vea el video, intente comprender la situación general.
Primero intente responder todas las preguntas de memoria. Luego, vuelva a ver el video e intente responder las preguntas que se perdió.
Mire el video nuevamente mientras lee el guión. Leer y escuchar al mismo tiempo lo ayudará a escuchar cada palabra individual y mejorará su precisión auditiva.
Hay una serie de actividades diferentes que se centran en la preparación de la examen, el vocabulario, la gramática y la estructura de las oraciones.

Imagine that instead of reading by lamplight, you could instead read with the aid of a glowing plant. It may sound implausible, but
scientists in the U.S. have shown that plants can be illuminated without needing genetic modification. During their research, the
team created watercress that glows with the hope that one day their research will help reduce our dependence on electric lighting.
A professor of chemical engineering at the Massachusetts Institute of Technology, Michael Straneau who led the research, told us how
it was done.
We've started to think about can we replace the things we encounter in our everyday lives. Like the things we make out of plastic
and electronic circuit boards, can we replace those with a living functioning plant.
Previously this year, we’ve made a plant that acts as a chemical sensor, and it will actually connect to a user's cellphone in the
vicinity using an infrared signal. This light emitting point was an obvious extension of our research. There are several reasons to do this.
So first, plants harvest their own energy from the sun. They don't need to be plugged in, but they also store that energy as sugar inside
the plant. So they're really a combination of a solar cell and a battery. Not just that, but they also have other interesting functions.
They'll self-repair, so if they're damaged, they actually fix themselves. They're also made entirely out of atmosphere carbon dioxide. They're
made of materials that degrade in water. We are not designing the plates so that it would be edible, but it turns out that the types of
nanoparticles that we are using are biocompatible in that way.
