Compensatory Strategies
A common set of communication devices involves
compensation for missing knowledge. These are called
“compensatory strategies”. We will elaborate here on three
of them.
Typical of beginning-level learners, for example, is
the memorization of certain phrases or sentences without
internalized knowledge of their components. These memorized
chunks of language, known as prefabricated patterns, include
“on the way to”, “Nice to meet you”, “I don’t speak English.”
Prefabricated patterns are sometimes the source of some fun.
In my first days of Kikongo learning in Africa, I tried to say, in
Kikongo, “I don’t know Kikongo” to those who attempted to
converse with me; I later discovered that, instead of saying
“Kizeyi Kikongo ko”, I had said “Kizoiele Kikongo ko” (I don’t
like Kikongo).
Code-switching is the use of a first or third language
within a stream of speech in the second language. Learners
in the early stages of acquisition might code-switch—use
their native language to fill in missing knowledge—whether
the hearer knows that native language or not. Sometimes the
learner slips in just a word or two, in the hope that the hearer
will get the gist of what is being communicated.
Yet another common compensatory strategy is a direct
appeal for help, often termed appeal to authority. Learners
may, if stuck for a particular word or phrase, directly ask a
proficient speaker or the teacher for the form (“How do you
say ?”). Or they might venture a possible guess
and then ask for verification from the proficient speaker. They
might also appeal to a bilingual dictionary for help. The latter
case can also produce some rather amusing situations. Once
a student of English as a second language, when asked to
introduce himself to the class and the teacher, said, “Allow me
to introduce myself and tell you some of the ...” At this point
he quickly got out his pocket dictionary and, finding the word
he wanted, continued, “some of the headlights of my past.”

language learning and teaching, 2006. Adaptado)

Francois Gouin wanted to learn German, and decided
that a year in Germany would be just the thing. At the
time of his trip to Germany, you would have found a rather
well-prepared, confident Francois Gouin who, despite his
young age, is already a gifted Latin and Greek professor.
With language learning already part of his career, he is
encouraged by his advisors at the College of Caen (Normandy,
France) to follow his pursuit of German and deepen his
studies at the University of Berlin. Excited with his prospects,
Gouin takes his determination and suitcases, and sets off for
Hamburg.
Once in beautiful Hamburg, with its countless shops and
bustling academic centers, Gouin unpacks his suitcases, and
immediately begins his language journey. He spends the first
10 days in seclusion studying in his room. With him, he has
a grammar book and a dictionary. He believes languages are
learned using “the classical process”, a process he says he
used for mastering Latin and Greek. To Gouin, the classical
process is the study of language through “an acquaintance of
its forms.” In other words, to learn a language, he feels it best
to faithfully study grammar and vocabulary!
After ten days of seclusion, he feels supremely confident,
and is anxious to try out his skills. To experiment with his new
knowledge, he decides to visit some university classes. Any
guesses how that went? Well, Gouin is in for a surprise. Here
are his own words: “But alas! In vain did I strain my ears; in
vain my eye strove to interpret the slightest movements of the
lips of the professor; in vain I passed from the first classroom
to a second; not a word, not a single word would penetrate to
my understanding.”
(Shane Dixon. The language learner guidebook: powerful tools to help you
conquer any language. [S.l.]: Wayzgoose, 2018.)
The experience Gouin goes through can be said
to confirm views and theories which state that the

Foreign language pronunciation instruction
in a communicative language teaching context:
amounts, practices and beliefs
The aim of this research was to examine three important
components of foreign language pronunciation instruction
and the connections between them: amount, actual practices,
and teachers’ beliefs. The data consisted of 45 video-recorded
lessons in French-as-a-foreign-language in six secondary
schools in Norway and semistructured interviews conducted
with the same teachers whose instruction was previously
video-recorded. The video-recorded lessons were analysed
for amount and actual practices of pronunciation instruction
and the interviews were analysed for teachers’ background
in and beliefs about phonetics and pronunciation pedagogy.
Results indicated that: (1) on average, pronunciation
instruction accounted for a very small part of the teaching
time (less than 2%); (2) despite the emphasis on segmentals
and suprasegmentals in pronunciation teaching literature,
explicit teaching of segmental and suprasegmental features
of speech was rare in the recorded material; (3) there is a
need for more training in and knowledge of phonetics and
pronunciation pedagogy. These findings might be used
to address concerns regarding the role of pronunciation
instruction in foreign language teaching and to define factors
that may account for the difficulty of making pronunciation
instruction an integral part of language teaching.

Leia o texto a seguir para responder à questão:
Inside the classroom, some learners seem to take
advantage of what is going on more than others. Aware of
this, teachers will frequently say that successful students
possess some or all of the following characteristics.
1. A willingness to listen: good learners listen to what
is going on – not just in the sense of paying attention,
but also in terms of really listening to the English
that is being used, soaking it up with eagerness and
intelligence.
2. A willingness to try new things: many good learners
are not afraid to ‘have a go’. They are prepared to
try things out and see how it works. Of course, not
all successful language learners are extroverts, but
the urge to use the language (loudly or quietly) is an
important one.
3. A willingness to think about how to learn: good
learners bring or invent their own study skills when
they come to a lesson. They think about the best way
to memorize vocabulary, the best way to read a text
(slowly, translating every word? Or quickly, trying to get
a general understanding?), the best method of drafting
and re-drafting a piece of writing.
4. A willingness to ask questions: although some
teachers can become irritated by students who are
constantly asking difficult (and sometimes irrelevant)
questions, the urge to find out why is part of a
successful learner’s equipment.
5. A willingness to accept correction: good learners
are prepared to accept corrections if it helps them.
They are keen to get feedback from the teacher and
act upon what they are told. But this only works where
teachers are able to offer constructive criticism. It
involves teachers in judging their students’ responses
to correction so that they can act accordingly.

A language function is a purpose you wish to achieve when you say or write something. If you say ‘I invite you’, you are performing the function of inviting. Of course you could also say ‘D’you want to come to the cinema?’ to make an invitation. There are many ways of inviting, apologising, agreeing, giving advice, asking for information etc.
If our students want to express themselves in speaking or writing, they need to know to perform these functions – in other words, how to use grammar and vocabulary to express certain meanings/ purposes.

Rain Is Coming to Burning Los Angeles and Will Bring Its Own Risks
Rain is forecast to begin as soon as Saturday
afternoon and to continue as late as Monday evening, says
meteorologist Kristan Lund of the National Weather Service’s
Los Angeles office. The area desperately needs the
precipitation, but experts are warily monitoring the situation
because rain poses its own risks in recently burned areas—
most notably the potential occurrence of mudslides and similar
hazards. “Rain is good because we’ve been so dry,” Lund
says. “However, if we get heavier rain rates or we get the
thunderstorms, it’s actually a lot more dangerous because you
can get debris flows.”
Fires do a couple of different things to the landscape
that can increase the risk of burned material, soil and detritus
hurtling out of control. When fires burn hot or long enough, they
leave an invisible layer of waxy material just under the surface
of the ground. This develops from decomposing leaves and
other organic material, which contain naturally hydrophobic or
water-repellent compounds. Fire can vaporize this litter, and
the resulting gas seeps into the upper soil—where it quickly
cools and condenses, forming the slippery layer.
When rain falls on ground that has been affected by
this phenomenon, it can’t sink beyond the hydrophobic layer—
so the water flows away, often hauling debris with it. “All of the
trees, branches, everything that’s been burned—unfortunately,
if it rains, that stuff just floats,” Lund says. “It’s really
concerning.” Even a fire that isn’t severe enough to create a
hydrophobic layer can still cause debris flows, says Danielle
Touma, a climate scientist at the University of Texas at Austin.
Under normal conditions, trees and other plants usually trap
some rain above the surface, slowing the water’s downward
journey. But on freshly burned land there’s much less greenery
to interfere; all the rain immediately hits the ground. [...]
Fortunately, the rain should also help firefighters tame
the blazes that remain active. The largest, the Palisades Fire,
is currently 77 percent contained. The second largest, the
Eaton Fire, is 95 percent contained. The Hughes Fire is third
largest and only 56 percent contained. A fire can be fully
contained but still burning. The containment percentage refers
to the amount of the perimeter that has barriers that firefighters
expect will prevent further spread.

Rain Is Coming to Burning Los Angeles and Will Bring Its Own Risks
Rain is forecast to begin as soon as Saturday
afternoon and to continue as late as Monday evening, says
meteorologist Kristan Lund of the National Weather Service’s
Los Angeles office. The area desperately needs the
precipitation, but experts are warily monitoring the situation
because rain poses its own risks in recently burned areas—
most notably the potential occurrence of mudslides and similar
hazards. “Rain is good because we’ve been so dry,” Lund
says. “However, if we get heavier rain rates or we get the
thunderstorms, it’s actually a lot more dangerous because you
can get debris flows.”
Fires do a couple of different things to the landscape
that can increase the risk of burned material, soil and detritus
hurtling out of control. When fires burn hot or long enough, they
leave an invisible layer of waxy material just under the surface
of the ground. This develops from decomposing leaves and
other organic material, which contain naturally hydrophobic or
water-repellent compounds. Fire can vaporize this litter, and
the resulting gas seeps into the upper soil—where it quickly
cools and condenses, forming the slippery layer.
When rain falls on ground that has been affected by
this phenomenon, it can’t sink beyond the hydrophobic layer—
so the water flows away, often hauling debris with it. “All of the
trees, branches, everything that’s been burned—unfortunately,
if it rains, that stuff just floats,” Lund says. “It’s really
concerning.” Even a fire that isn’t severe enough to create a
hydrophobic layer can still cause debris flows, says Danielle
Touma, a climate scientist at the University of Texas at Austin.
Under normal conditions, trees and other plants usually trap
some rain above the surface, slowing the water’s downward
journey. But on freshly burned land there’s much less greenery
to interfere; all the rain immediately hits the ground. [...]
Fortunately, the rain should also help firefighters tame
the blazes that remain active. The largest, the Palisades Fire,
is currently 77 percent contained. The second largest, the
Eaton Fire, is 95 percent contained. The Hughes Fire is third
largest and only 56 percent contained. A fire can be fully
contained but still burning. The containment percentage refers
to the amount of the perimeter that has barriers that firefighters
expect will prevent further spread.
