1
From VOA Learning English, this is the Agriculture Report.
2
New studies have found that a chemical commonly used to fight plant disease is harming honeybees.
3
Experts say the chemical may be partly to blame for the widespread loss of honeybees in the United States.
4
The insects are important to farmers.
5
When a honeybee lands on a flowering plant,
6
pollen sticks to its legs.
7
When the bee lands on another flower,
8
some of the pollen falls off and fertilizes the second plant.
9
The act of pollination is important to the growth of many fruits,
10
vegetables, nuts and other crops.
11
Yet about 30% of honeybees in the United States and other areas have died in recent years.
12
Dennis Van Ingelsdorp is a researcher at the University of Maryland.
13
He wants to learn why so many bees are dying.
14
His research team examined pollen grains that honey bees carried to their hives.
15
They found that the pollen contained high levels of 35 different pesticides,
16
chemicals used to kill insects.
17
They also found that bees that ate some fungicides became infected with a deadly microorganism called Nosema.
18
Fungicides are used to protect against fungi and are widely used for agriculture purposes in the United States.
19
Mike Leggett studies pesticides for the pest management industry group CropLife America.
20
He says many of the pesticides found in the pollen examined by Dennis Van Engelsdorp actually protect bees from Nosema.
21
Honeybees are important to agriculture.
22
This makes the search for an answer to their deaths especially urgent for Mr. Van Engelsdorp's team.
23
As he notes, one in every three bites of food we eat is somehow pollinated by honeybees.

About This Lesson

In this lesson, learners will focus on understanding a critical issue in agriculture: the decline of honeybee populations. By studying the provided video transcript, you will practice key vocabulary related to agriculture and environmental science. This lesson will also help you enhance your English speaking practice through shadowspeak, which allows you to imitate the natural speech patterns and intonations of native speakers. You’ll improve your English pronunciation while learning the significance of honeybees in our food ecosystem, an important topic for discussions, especially in the context of the IELTS speaking practice.

Practice Tips

To effectively improve your English pronunciation and speaking skills, it is beneficial to engage in shadowing practice with this video. Follow these tips:

  • Watch with Intention: First, watch the video without pausing to understand the overall message regarding honeybee loss and its impact on agriculture.
  • Slow it Down: Use YouTube's playback settings to slow down the video speed. This will make it easier to mimic the natural pacing of speech.
  • Pause and Repeat: After listening to a segment, pause the video and repeat what you heard. Focus on mimicking the intonation and rhythm of the speaker.

Through dedicated practice, you will not only expand your vocabulary but also effectively learn English with YouTube, making your learning experience engaging and informative.

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.
