We use one (singular) and ones (plural) to avoid unnecessary repetition.

Which is your car, the red one or the blue one?
My trousers are torn. I need some new ones.
See those two girls? Helen is the one on the left.
Let’s look at the photographs. The ones you took in Paris.

Hello , everyone. I don't understand this sentences: I hope this holiday will be one to remember. What mean it is? Why we use " will be"?

Hello drphat,

I hope is commonly used to express a wish about something in the future and "one to remember" means "a holiday to remember". In this sentence, the speaker is saying that they hope that the holiday they are about to go on is very good, i.e. that it is a holiday that they will fondly remember for many years.

I hope this helps - please let us know if not.

Best wishes,

hello everyone
I'm new user
I like this test

I am having problem opening the question page.

Hi Jacob,

Do you mean the exercises? I could see them just now, so it appears they are working. What kind of device are you using? Does it have the latest version of Flash installed? These exercises are currently made with Flash, and so do not work on some devices (e.g. iPhones or iPads). We are working on a solution to this, but it has not yet been implemented.

Which exercise you guys are talking about.
Where I can find the exercise

Hi ZahidShaikh,

There is an exercise above (titled Pronouns: one/ones). What kind of device are you using? If you're using a tablet or phone, you need to have Flash installed to see most of our games and exercises. If you have a device with iOS, I'm afraid you won't be able to see it. We're working on a solution to this and hope to have it solved in the next few months, but for now you may have to change devices to see the exercises.

Best wishes,

Question: why the correct answer is singular (one)? my answer was plural (ones) because I saw previous sentence are plural (new mobiles are.......)

Thank you very much :)

Hello aimee_auzzie,

I've checked the exercise and the correct answer to Q2 is 'ones', not 'one'.  Could you check again please?  Perhaps you misread it.
