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.

Please help me to answer my curiosity Dear Kirk. on above exercise, point number 2

2. The new mobiles are much lighter the old ....(ones)

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.

Sir is this sentence is correct?
I need some new glasses. The ones i have at the moment are broken.

when i read the sentence it seems to be incomplete...


Hi peter,
"The ones i have at the moment are broken". starts with "the ones"? when i read this it's look like incomplete sentence.

Hi Arumugam,

As is explained above, one or ones are often used to avoid repeating other nouns. In sentence 5, the ones takes the place of and refers to the glasses in the previous sentence.

I can understand that it may sound strange to you, but please know that it is very common in both written and spoken English!
