EXPRESSING
DEGREES OF CERTAINTY
Eğer bir konuda kesin olarak gerçeği
bilmiyorsak, o konuda tahminlerde bulunuruz. Bu tahminlerimizi, derecelerine
göre, "must, may, might, could" gibi modal yardımcı fiilleriyle ifade ederiz. Şimdi
zamanlarına göre bu yapılan inceleyelim.
1 PRESENT
TIME
a)
Positive Statements:
Eğer bir gerçeği kesin olarak biliyorsak, modal
kullanmaya gerek yoktur.
— Why is Peter at
home today? Why didn't he go to work?
— He is ill. (I know that he is ill.)
Gerçeği kesin olarak bilmiyorsak ama güçlü
bir tahminde bulunuyorsak, "must" kullanırız.
— Why is Peter at
home today?
— Well, he must be ill. (Hasta olmalı.)
(I saw
him last night, and he wasn't feeling very well, so I'm sure that he is ill
today.)
— The baby is
crying. Why?
— She must be hungry. (Aç olmalı.)
She
hasn't eaten anything for three hours.
— How does he know
so much about everything?
— Well, he must read a lot. (Çok okuyor olmalı.)
Gerçeği kesin olarak bilmiyorsak ve güçsüz
bir tahminde (ya da tahminlerde) bulunuyorsak, yani aklımıza gelen olasılıkları
ifade etmek istiyorsak, "may,
might, could" kullanırız.
— Why is Peter at
home today?
— Well, I don't
know. He may/might/could be ill. (Hasta olabilir.)
(There may be some
other possibilities, but I don't know. Perhaps/ Possibly/Maybe * he is ill. He is
probably ill. It's likely that he is ill.)
"May", "might"
ve "could" aynı anlama sahiptir ve Türkçe'ye ".......... olabilir"
biçiminde çevrilir.
— Why is the baby
crying?
— I don't know.
There may be several reasons. She may
be hungry, or she might need a nappy change or she could need burping.
— Why is Peter at
home today?
— He is ill. (100% sure)
— Why
is Peter at home today?
— He must be ill. (95% sure)
— Why
is Peter at home today?
— He may/might/could be ill. (About 50% sure)

* "Maybe" bitişik yazılınca bir zarftır.
Cümlenin başında kullanılır: "Maybe he is ill.
(Belki de hastadır.)
"May be", "modal+verb" kullanımıdır:
He may be ill. (Hasta olabilir.)
b) Negative Statements
Eğer gerçeği kesin olarak biliyorsak, durumu modal kullanmadan ifade ederiz.
— Why isn't Peter
eating anything?
— He isn't hungry. (I know that he is not hungry.)
Gerçeği kesin olarak bilmiyorsak ama bazı
temellere dayanarak güçlü bir tahminde bulunmak istiyorsak "can't"
ya da "couldn't" * kullanırız. Bu yapıları Türkçe'ye
"........ olamaz, imkansız"biçiminde çevirebiliriz.
— Your brother says he is very hungry.
— No, he can't/couldn't be hungry.
He ate a huge meal just half an hour ago. (It's impossible that
he is hungry.)
(Hayır, aç olamaz. Aç
olması imkansız.)
— Your brother says
he is broke.
— No, he can't/couldn't be
broke. I gave him ten million liras just an hour ago. (It's impossible that he
has no money.)
Yine güçlü bir tahmini ("can't" ve "couldn't"
a göre daha cılız),
aklımıza gelen en mantıklı tahmini ifade etmek için "must not **" kullanırız. Bu kullanımıyla "must
not" genellikle
kısaltılmaz.
— Your brother isn't eating his lunch.
— Well, he must
not be hungry.
(Aç olmamalı. Herhalde aç değil.)
(Normally, he eats everything on his plate. If he isn't eating now, I'm
almost sure that he isn't hungry. I can't think of any other reasons.)
— Look! Peter is
eating only salad. He hasn't even touched his fish.
— Well, he must
not like fish.(Balığı sevmiyor
olmalı. Herhalde balığı sevmiyor.)
— Jane always gets
low grades in history.
— She must not study hard
enough. (Yeterince çalışmıyor olmalı. Herhalde
yeterince çalışmıyor.)
Tahminimiz güçsüz ise, sadece aklımıza
gelen olasılıkları ifade ediyorsak "may not" ya "might
not" kullanırız.
— Why is Peter
eating only salad? He hasn't even touched his fish.
— I don't know. He may
not/might not like fish.
(Balığı sevmiyor
olabilir. Belki de balığı sevmiyordur.) (Maybe/Perhaps he doesn't like
fish.)
— Why does she
always get low grades in history?
— I don't know. She may
not study hard enough.
(Perhaps she doesn't study hard enough.) (Yeterince çalışmıyor olabilir.)
— I'm going to see
the manager.
— Phone him first.
He may/might not be in
his room. (Odasında olmayabilir.)
He isn't in his room. (100% sure)
He can't/couldn't be in
his room. (99% sure)
He must not be in his room. (95% sure)
He may not/might not be in
his room, (about 50% sure)
|
* Could güçsüz bir tahmin, couldn't ise çok güçlü
bir tahmin bildirir.
** Tahminde
bulunurken kullanılan yapılardan "must not" sadece American English'de kullanılır. British English'de "must
not" yerine
"can't/couldn't" kullanılır.

home.

evde kalmayı tercih ettim.)
(The result is: I didn't
go to the cinema.)
b) Last
week, my husband was going to have a match with his friends, but he didn't
go. Later we found out that the match had been cancelled, so he couldn't
have gone even if he had wanted to. (İsteseydi
bile gidemezdi.)
(The result is: He didn't
go to the match.)

phoned her, she wasn't at home.

olabilir.)

she was at the cinema when I phoned her.)
b) He couldn't have gone to the match

.........)
(The result is: It's impossible that he went to
the match yesterday.

5 FUTURE TIME
Geleceğe ilişkin
olaylardan sözediyorsak, "will, should/ought to, may /might /could"
kullanabiliriz.
"Must" geleceğe ilişkin tahminde bulunurken kullanılmaz. Ancak,
içinde bulunduğumuz anda gelecekte bir eylemin olacağına ilişkin belirtiler
varsa, 'must be doing' kullanabiliriz.

giving a huge party for her
birthday next week. I saw her buying lots of food and drinks at the market
today.
Eğer bir olayın
olacağından kesin olarak eminsek, "will" kullanırız.
— He will pass his driving test. He is very good at driving.
Güçlü bir
tahminde bulunuyorsak, "should/ought
to" kullanırız.

car very well. He should/ought to pass the test.
