Harvesting and Processing cocoa beans Listening

test 4 you will hear a number of different recordings and you will have

to answer questions on what you hear there will be time for you to read the

instructions and questions and you will have a chance to check your work all the

recordings will be played once only the test is in four sections at the end of

the test you will be given ten minutes to transfer your answers to an answer

sheet now turn to section 1 section 1 you will hear a woman telephoning a car

rental company to ask about car renting services first you have some time to

look at questions 1 to 5

you

you

you will see that there is an example which has been done for you on this

occasion only the conversation relating to this will be played first hello first

choice car rental how may I help you oh good morning I'm calling for some

information about your car renting services and I will be going on a family

holiday to your city from Ohio next month the woman says that she is an

American so American has been written in the space now we shall begin you should

answer the questions as you listen because you will not hear the recording

a second time listen carefully and answer questions one to five

hello first choice car rental how may I help you okay no problem it's our

pleasure to serve you could you please tell me your name and contact

information first okay I've got that and how can I send you our quotation if

you are satisfied with our arrangement his email all right or should I send it

by post that's no problem I think it should be within my budget of $50 you

know we have various caravans at different renting prices according to

the class of vehicle facilities inside mileage etc I'd recommend the Explorer

taking your budget into consideration which is of good value and will cost you

$39 per day is that okay I'm glad that you like it so do you have any

particular requirements about your room in the van one twin bed no problem for

the facilities I think a kitchen is the most important and of course the stove

before you hear the rest of the conversation you have some time to look

at questions six to ten

you

you

now listen and answer question six to ten in our vans such as Explorer there

are all the basic bedding materials you need like pillows and blankets as well

as some equipment for daily life and many things can be added into your room

according to your needs such as a coffee maker alright

I've taken notes of all these things actually all our vans should be taken

from our company which is not too far from the city center so we can pick you

up from the Center for free yes that's okay picked up from the airport as we

are foreigners in your country and not familiar with the transport system

that's all right yes it is no problem with that comes the information for the

insurance I need the drivers name and age that is

my daughter Chris 19 the youngest driver amongst us three I'm sorry but our

company only accepts Caravan drivers age 25 or over according to our regulations

so and where was your driving license issued I mean the country your country

yes that might be better so your registration number is

the end of section 1 you now have half a minute to check your answers

now turn to section 2 section 2 you'll hear a talk between a host and a

professor called Allison downing about cocoa beans first you have some time to

look at questions 11 to 16

you

you

you you

you

you

you

now listen carefully and answer questions 11 to 16 hello and welcome to

today's talk here with me is the famous botanist professor Allison downing so

Allison tell us something about cocoa beans cocoa beans also called cacao

beans are the primary constituent in making chocolate grown in tropical areas

in South and Central America West Africa and Asia the cocoa tree is often raised

on small family-owned farms when the harvested pots are open to expose the

beans the pulp and cocoa seeds are removed and the rind is discarded the

pulp and seeds are then piled in heaps placed in bins or laid out on grates for

several days during this time the seeds and pulp undergo a process called

sweating where the thick Pope liquefies as it ferments the fermented pulp

trickles away leaving cocoa seeds behind to be collected this is when the beans

are harvested and then the bags holding them are ready to be transported but the

most important step in processing the cocoa bean is cleaning it once the beans

are unloaded from the railroad cars the packages are opened and then weighed by

machines then the pods are split and the seeds or beans are covered with a sweet

white pulp or mucilage on arrival at the factory the cocoa beans are sorted and

put in a hopper to be cleaned more rigorously the wet beans are then

transported to a facility so they can be fermented and dried they are fermented

for four to seven days and must be mixed every two days they are dried for five

to fourteen days depending on the climate conditions the fermented beans

are dried by spreading them out over a large surface and constantly raking them

then the beans are ready to be roasted now roasting takes place at a high

temperature and there the beans are boiled in a heated chamber

during the roasting process the beans will be expanded and cracked but prior

to this the beans are trodden and shuffled about using bare human feet

during this process red clay mixed with water is sprinkled over the beans to

obtain a finer color polish and protection against molds during shipment

to factories in the United States the Netherlands the United Kingdom and other

countries now back to what I was saying after the beans are cracked they need to

be cooled then the roasted beans are sealed in pockets before you hear the

rest of the talk you have some time to look at questions 17 to 20

now listen and answer questions 17 to 20

well that is not a simple process is it but someone told me that different

roasting levels of coffee can lead to different kinds of flavors yes roasting

coffee transforms the chemical and physical properties of green coffee

beans into roasted coffee products the roasting process is what produces the

characteristic flavor of coffee by causing the green coffee beans to change

in taste unroasted beans contain similar if not higher levels of acids protein

sugars and caffeine as those that have been roasted but lack the taste of

roasted coffee beans due to the may lard and other chemical reactions that occur

during roasting the vast majority of coffee is roasted commercially on a

large scale but small-scale commercial roasting has grown significantly with

the trend toward single origin coffees served at specialty shops some coffee

drinkers even roast coffee at home as a hobby in order to both experiment with

the flavor profile of the beans and ensure the freshest possible roast so

here I'm going to introduce some of these roasted coffee beans and their

special flavors now the first crack is lighter bodied and has a higher acidity

level with no obvious roast flavor and is popular for its special mild taste

this level of roast is ideal for tasting the full original character of the

coffee the green beans are raw unroasted coffee beans they are strictly hard

beans with a smoky flavor and a slightly acidic we've also got French Roast

and the flavor that comes across in French roast coffee usually has more to

do with the roasting process than the actual quantity of the beans by the time

the beans are dark enough to qualify as French most of their original flavor has

dissipated in its place come the flavors of caramelizing sugar bitter sweet

coffee and often a bit of chocolate and finally espresso

smokey that is coffee brewed by forcing a small amount of nearly boiling water

under pressure through finely ground coffee beans espresso is generally

thicker than coffee brewed through other methods has a higher concentration of

suspended and dissolved solids and has creamer on top as a result of the

pressurized brewing process the flavors and chemicals in a typical

cup of espresso are very concentrated espresso is also the base for other

drinks such as cafe latte cappuccino cafe macchiato cafe matcha flat white or

Caffe americano that is the end of section 2 you now have half a minute to

check your answers you

you

you

you

you you

now turn to section 3 section 3 you will hear two students talking about the more

with the lecturer first you have some time to look at questions 21 to 26

you you

now listen carefully and answer questions 21 to 26 thank you all for

coming here today to hear about the mower a kind of animal which has been

extinct for a long time well first of all we look at what the mower are the

mower our nine species of flightless birds endemic to New Zealand they were

the dominant herbivores in New Zealand's forests shrubland and subalpine

ecosystems for thousands of years but around five hundred years ago they all

went extinct when I mention extinct animals during ancient times you may

immediately think of dinosaurs which disappeared around 66 million years ago

fossils of dinosaurs which we used to study a large and number but not many of

those of MOA remain though both animals appeal to people today so the MOA sound

more mysterious now but Sir I've got a question about these flightless birds

how can we distinguish them from other birds that's a good question birds are

commonly characterized by being warm-blooded having feathers and wings

usually capable of flight and laying eggs while a flightless MOA until their

extinction were the largest birds in the world their heads are relatively small

in relation to their bodies and they are the only wingless Birds lacking even the

vestigial wings and substantial tail bones in their family that's impressive

but were they born to be like that I mean when they were chicks yes

absolutely so let's move on to the chicks the eggs

of MOA were laid in nests and incubated for about two months the chicks would be

well developed upon hatching and probably would be able to leave the

nests to feed on their own almost immediately I've heard that the male MOA

are thought to have incubated the eggs is that true I think there is a

possibility for that I've read somewhere that the sex specific DNA recovered from

the outer surfaces of eggshells suggested that these eggs were likely to

have been hatched by the but we still need to consult more but I

have a question there has been some occasional

speculation that the mower was still alive because someone said they had

caught sight of them in New Zealand in the late 19th century or even the 20th

do you think it's possible I'm not amazed by that since that kind of thing

has been claimed several times but I find it funny because no reliable

evidence of mower tracks has ever been found and experts still contend that

mower survival is extremely unlikely so what was the reason for the mowers

extinction I wonder if it was global warming or some other factors related to

their living environment well before the arrival of human settlers in New Zealand

the mowers only predator was the massive Hass Eagle then the Maori arrived some

time before seee 1300 and all mower general was soon driven to extinction by

hunting what a horrible thing before you hear the rest of the talk you have some

time to look at questions 27 to 30

you

you

now listen and answer questions 27 to 30

all right now let's look at the features of some species of MOA

the South Island giant MOA may have been the tallest Birds ever known and the

second tallest of the nine MOA species is the North Island giant MOA with the

females being markedly larger than males both in weight and height and I've heard

that the smallest of the MOA birds are the coastal MOA is that right yes you

were right and have you heard about any other kind of MOA before I know the

crested MOA the egg stay late may be larger than others as they mainly lived

in the remote interior of the southern island their fossils are rare or absent

in archaeological sites and no egg remains have yet been identified

are there any species of MOA that have got more fossils yes of course a

considerable amount of remains of the stout legged MOA exist due to the well

preserved properties of their habitat their skulls reveal relatively bad

vision a good sense of smell and a very short bill then there is the eastern

moan they were remarkable in having very long

and narrow wind pipes which probably enabled them to make louder more

resonant calls than those of other MOA and had the greatest vocal abilities so

they could communicate when they could not see each other in the forest or at

night they used a range of sensors apart from sound in their search for food such

as their sense of smell and vision

time measurement first you have some time to look at questions 31 to 40

you

you

you

you

you

you

now listen carefully and answer questions 31 to 40 good morning everyone

today I'm going to talk about the research project I've been involved in

on time measurement do you know how time is measured consider how we measure

length and how with time we encounter a difficulty before we could grasp it it

would slip through our fingers in fact as we can see we are forced to have the

resource to measure something else the movement of something in space or a set

of movements in space all the methods that have been employed so far really

measure time by a motion in space the measurement of time is no easy

matter a scientific unit only arrived at after much thought and reflection as the

most primitive form of measurement the Sun seems to be natural ever since man

first noticed the regular movements of the Sun and stars

we have wondered about the passage of time prehistoric people first recorded

time according to the sun's position to start off let us take noon which is when

the Sun is on the meridian at the highest point of its course across the

heavens and when it casts the shortest shadow but this measurement which was

regarded as a major one in ancient times was less important than the natural

events that occurred the earliest natural events that had been recognized

were in the heavens but during the course of the year there were many other

events that indicated significant changes in the environment seasonal

winds and rains the flooding of rivers the flowering of trees and plants and

the breeding cycles or migration of animals all led to natural divisions of

the year and the further observation and local customs led to the recognition of

the seasons years later precise measurements were invented because the

passage of time was extremely important for astronomers and priests who were

responsible for determining the exact hour for daily rituals and for important

religious festivals a part from the connection with religion

accurate time measurement was also related to the government since they

divided the day or the night into different periods in order to regulate

work and various events for thousands of years devices had been used to measure

and keep track of time the current sexagesimal system of time

measurement dates back to approximately 2000 BCE from the Sumerians it was found

that the earliest ancient timekeepers were mainly invented and used in

Mesopotamia where the water clock was introduced from as well as in North

Africa especially in the area of ancient Egypt so now I'd like to introduce you

to some of the most well known ancient timekeepers as well as the disadvantages

of them for which they were replaced by various new forms of clocks that were

used afterwards a sundial is a device that tells the time of day by the

apparent positioning of the Sun in the sky in the narrowest sense of the word

it consists of a flat plate and a Norman which casts a shadow onto the dial as

the Sun appears to move across the sky the shadow aligns with different hour

lines which are marked on the dial to indicate the time of day however it was

quickly noted that the length of the day varied at different times of the year

therefore there could have been a difference between clock time and

sundial time in addition the sundial was of no use at night so a water clock was

invented the water clock or CLEP Sidra appear to have been invented around 1500

BCE and was a device which relied on the steady flow of water from or into a

container measurements could be marked on the container or on a receptacle for

the water it was reliable but the water flow still depended on the variation of

pressure and temperature from the top of water in the container as the technology

of glassblowing developed from sometime in the 14th century it became possible

to make and glasses originally they were used as

a measurement for periods of time like lamps or candles but as clocks became

more accurate they were calibrated to measure specific periods of time the

drawback however as you can imagine was the limited length of time they could

measure the last time keeper to be introduced is the fire candle clock

candle clocks took advantage of a simple concept the slow and consistent nature

of a burning wax candle by utilizing this process our ancestors were able to

keep steady track of the time the clocks were created by engraving the length of

the candle with evenly spaced markings each marking represented a single unit

of time and as the wax burned down each hour would disappear however the drafts

and the variable quality of the wax mainly influence the time of burning

like oil lamps candles were use to mark the passage of time from one event to

another rather than tell the time of day
