Is this homework?
Which phrase should I choose for each of the following two blanks? or both?
- Last year my wife and I decided to take the plunge, we signed up for residential solar power. After a lot of research weighing solar energy pros and cons, we decided to ____________ with Solar City.
- The county has ____________ four youngsters for next season, including two local 18-year-olds — all-rounder John Hughes and batsman Russell Warren — on summer contracts.
Are these two phrases interchangeable in these two cases? Is there geographical preferences for either one, say in BrE and AmE?
In my opinion, you can use both phrases in both blanks. However, "sign up" would be better for the first and "signed on" would be better for the second. This is from an AmE speaker. We will have to wait for BrE speakers.
In BrE, I would use "sign up" with the first example about energy providers. Having said that, the use of "signed up" in the first half makes the use of "sign up" in the second half rather repetitive. In reality, I would probably say "... we decided to go with Solar Energy".
In the second, certainly with soccer, we simply say "signed".
Liverpool FC have signed two sixteen-year-olds.
Brighton and Hove Albion have signed Kenny Dalglish.
I'm not sure whether "signed" also works for cricket which appears to be the sport referred to in your second example.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
Yes, it does.
