Hi! You’ve got a mistake in the quiz!
“How is the new Radiohead album?” Speculate with 90% certainty in the present.
It could be good.
!!–>I has to be good.<–!! *should be IT because it's a correct answer.*
It might be good.
It may be good.

Other than that, it's very good! Thanks!

Saturday, May 28th 2011

    You’re right! Fixed now!

Saturday, May 28th 2011

hi MR.alex i have scored 9 out of 10 >> i have question about “What’s the temperature like today?” Speculate with 50% certainty in the present.

It must be at least 15 degrees.
It may be at least 15 degrees.
It could have been at least 15 degrees.
It has got to be at least 15 degrees.

why it is

It may be at least 15 degrees?

and thank you for lesson

Saturday, May 28th 2011


    Saturday, May 28th 2011

    As there is asked to speculate with 50% certainly, so option “a” and option “d” never be correct and the right answer is option “b”. Option “c” is not be correct. (Could have + past participle means that something was possible in the past, or you had the ability to do something in the past, but that you didn’t do it.)

Monday, February 10th 2014

Leaning thx

Thursday, May 8th 2014

Dear Professor Alex,

The negative forms are not explained in your lesson; the more you have made some mess about forms must vs must not; must vs have not to.

must means command or obligsation;

must not is a prohibition in other words negative command;

when expressing obigatiion using must – the negative form is have not to do sth

That is why your first negative form – must not – is not clear for me.The meaning of it.

Best regards,

Monday, May 19th 2014

sir..what’s the difference between (may.might.could)

Tuesday, May 20th 2014

thank you Alex …you explaining very simple and perfect i appreciate for your unique training i can to find from your face that you must be very kindness too….but in this lesson i did not understand that you mention less certain 50% …so must be under 50% or at least 50%..?

Thanks a lot

Wednesday, February 18th 2015

Dear Alex,
Thank you for your valuable lesson.
I have one question regarding a difference of a degree of certainty between should and other verbs you explained this lesson. According to your previous lesson referring to “should and must”, you mentioned that should is also used to talk about certainty. So, I am wondering how degree of certainty “should” have, compared with other verbs such as must, have to, or might.
Thank you.

Sunday, March 15th 2015

thank you Alex, I did not understand the third question.
