Could you please check these few sentences? Thank you
1) I've been a Tim subscriber for two years.
I top up my mobile every two weeks.
I recharge it every evening.
2) I keep in touch with my friends by sending them email and by chatting on Facebook.
3) I joined Facebook last summer.
I prefer sending email to texting my friends.
All are fine. =)
Certainly! I'd be happy to check your sentences.
1) I've been a Tim subscriber for two years.
I top up my mobile every two weeks.
I recharge it every evening.
These sentences are grammatically correct. However, there is one small change that could be made for clarity: "I recharge it every evening" would flow better as "I recharge my mobile every evening."
2) I keep in touch with my friends by sending them email and by chatting on Facebook.
This sentence is also grammatically correct. Nothing needs to be changed.
3) I joined Facebook last summer.
I prefer sending email to texting my friends.
These sentences are grammatically correct. However, to improve clarity, you could modify the second sentence to: "I prefer sending emails to texting my friends."
Great job with your sentences! If you have any more questions or need further assistance, feel free to ask.
