1
section three you will hear part of a seminar in which a researcher called grant freeman discusses his work on australian
2
honeybees with a group of students first you have some time to look at questions 21-24
3
now listen carefully and answer questions 21-24
4
good morning everyone uh in today's seminar grant freeman a biologist who specializes in identifying insects and who works for the australian quarantine
5
service has come to talk to us about his current research work right well uh over to you grant good morning everyone i'm sure that you know that the
6
quarantine service regulates all food brought into australia well obviously they want to protect australia from diseases that might come
7
in with imported goods but they also want to prevent insect pests from being introduced into the country and that's where i have a part to play
8
anyway my current research involves trying to find a particular type of bee the asian honey bee and finding out
9
whether there are any of them around in various states of australia we discovered a few of them in queensland once and eradicated them
10
now we're pretty keen to make sure that there aren't any more getting in particularly to new south wales and other states what's wrong with asian honey bees are
11
they so different from australian bees well in fact they look almost the same but they are infested with mites
12
microscopic creatures which live on them and which can seriously damage our own home-grown bees or could even wipe them
13
out well what would happen if australian bees died out well the honey from australian bees is of excellent quality much better than
14
the stuff the asian bees produce in fact australia exports native queen bees to a large number of countries because of this
15
when the european honey bee was first discovered out in the bush we found they made really unpleasant honey and they were also too big to pollinate many of
16
our native flowers here in australia that must have had a devastating effect on the natural flora did you lose any species
17
no we managed to get them under control before that happened but if asian bees got in there could be other consequences
18
we could lose a lot of money because you might not be aware but it's estimated that native bees pollination of flower
19
and vegetable crops is worth 1.2 billion dollars a year so in a way they're the farmer's friend
20
oh and another thing is if you're stung by an asian honey bee it can produce an allergic reaction in some people so they're much more dangerous than native
21
bees
22
before you hear the rest of the seminar you have some time to look at questions 25 to 30.
23
now listen and answer questions twenty five to thirty
24
how will you know if asian bees have entered australia we're looking at the diet of the bird called the rainbow bee eater
25
the bee eater doesn't care what it eats as long as they're insects but the interesting thing about this bird is that we are able to analyze
26
exactly what it eats and that's really helpful if we're looking for introduced insects how come because insects have their skeletons
27
outside their bodies so the bee eaters digest the meat from the inside then they bring up all the indigestible
28
bits of skeleton and of course the wings in a pellet a small ball of waste material which they cough up that sounds
29
a bit unpleasant so how do you go about it in the field we track down the beaters and find their favorite feeding spots you know the places where the birds
30
usually feed it's here that we can find the pellets we collect them up and take them back to the laboratory to examine the contents
31
how do you do that the pellets are really hard especially if they've been out in the sun for a few days so first of all we treat them by
32
adding water to moisten them and make them softer then we pull them apart under the microscope everything's all scrunched up but we're
33
looking for wings so we just pull them all out and straighten them then we identify them to see if we can find any asian bee wings and how many have you
34
found so far our research shows that asian bees have not entered australia in any number it's a good result and much
35
more reliable than trying to find live ones as evidence of introduced insects well that's fascinating thank you grant for those insights i hope that you might
36
inspire some of our students here to conduct some similar experiments
37
that is the end of section three you now have half a minute to check your answers

¿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.
