1
From VOA Learning English, this is the Agriculture Report.
2
Scientists have discovered the genetic secrets of two unpopular members of two favorite food families.
3
They hope the discoveries will produce tastier tomatoes and stronger rice.
4
The scientists discovered the complete set of genetic information of African rice and wild tomatoes.
5
They published their studies in two reports in the journal Nature Genetics.
6
There are good reasons African rice and wild tomatoes have not been popular.
7
Asian rice is more productive and easier to process than African rice,
8
and the wild tomato is poisonous.
9
Rod Wing is a plant biologist at Arizona State University.
10
He helped map the African rice genes.
11
He says African rice can grow in salty and even poisonous soil.
12
And it can also grow around weeds and in extremely dry conditions.
13
He says this strength is increasingly important as climate change makes crop production more difficult.
14
Scientists can now identify the genes that control what is good about African rice and combine those genes with Asian rice.
15
They will be able to make better rice faster.
16
The wild tomato also has some good qualities.
17
Scientists found that it can grow in salty as well as very dry conditions like the African rice.
18
The map identifies the genes that may be responsible for these qualities.
19
Bjorn Usadel is with Germany's RWTH Aachen University,
20
which also took part in the mapping.
21
Mr. Usadel says researchers also found differences in the genes of wild and farm-grown tomatoes that taste and smell.
22
He says this could help scientists improve the flavor of tomatoes.

Step-by-step Shadowing Guide

To effectively use this video for your learning, follow this step-by-step shadow speech technique that can enhance your improve English pronunciation:

  1. Watch the video: Begin by watching the entire video without pausing to grasp the overall context.
  2. First listen: Play a short segment of the transcript, like “the complete set of genetic information,” and focus on understanding the pronunciation and intonation.
  3. Pause and repeat: After listening, pause the video and repeat what you heard, mimicking the speaker’s pitch and rhythm. This practice is often known as shadowspeak.
  4. Break it down: If the entire sentence seems challenging, break it into smaller phrases. For instance, practice “produce tastier tomatoes” separately before combining it with the rest of the sentence.
  5. Record yourself: Use a recording device to capture your voice as you shadow the phrases. Listening to your recordings will help you identify areas for improvement.
  6. Review and refine: Finally, revisit the video to listen to the original speaker once again. Try to notice subtle differences in pronunciation that you might have missed on the first watch.

By consistently practicing through this shadow speak method, you will not only enhance your listening skills but also improve your English speaking abilities, making your practice sessions both engaging and educational. Dive into YouTube videos like this one and enjoy the journey of learning English!

Qu'est-ce que la technique du Shadowing ?

Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
