Can/ Could/ Would you …? etc. (Requests, offers, permission and invitations) Can/ Could/ Would you …?)



Asking people to do things (requests)
We often use can or could to ask people to do things:

  • Can you 
  • wait a moment, please? or
    Could you wait a moment, please?
  • Liz, can you do me a favour?
  • Excuse me, could you tell me how to get to the station?
  • I wonder if you could help me.
Note that we say ‘Do you think (you) could…?’ (not usually ‘can’):
  • Do you think you could lend me some money until next week?

We also use will and would to ask people to do things (but can/could are more usual):
·         Liz, will you do me a favour?
·         Would you please be quiet? I'm trying to concentrate.
Asking for things
To ask for something we use Can I have…? or Could I have…?:
·         (in a shop) Can I have these postcards, please?
·         (during a meal) Could I have the salt, please?
May I have…? is also possible (but less usual):
·         May I have these postcards, please?
Asking for and giving permission
To ask for permission to do something, we use can, could or may:
·         (on the phone) Hello, can I speak to Tom, please?
·         Could I use your phone?’ ‘Yes, of course.’
·         Do you think I could borrow your bike?
·         May I come in?’ ‘Yes, please do.’
To give permission, we use can or may.
·         You can use the phone. or You may use the phone.
May is formal and less usual than can or could.
Offering to do things
To offer to do something, we sometimes use Can I…?:
·         Can I get you a cup of coffee?’ ‘Yes, that would be very nice.’
·         Can I help you?’ ‘No, it's all right. I can manage.’
You can also use I'll… to offer to do things (see Unit 21):
·         You look tired. I'll get you a cup of coffee.
Offering and inviting
To offer or to invite we use Would you like…? (not ‘do you like’)
·         Would you like a cup of coffee?’ ‘Yes, please.’
·         Would you like to come to dinner tomorrow evening?’ ‘Yes, I'd love to.’
I'd like… is a polite way of saying what you want:
·         (at a tourist information office) I'd like some information about hotels, please.
·         (in a shop) I'd like to try on this jacket, please.

Text: THE FUTURE OF STEM CELLS



Health  Problems  that Might be  Treated by Stem Cells
What Is the Goal of Stem Cell Research?
Why don’t we live forever?
Because we get sick?
Because we get old?
Because we get hurt and can’t heal?

                All of these are correct. Each one results from a failure of the boby’s ability to grow, maintain, or repair itself – functions that depend on  our stem cells.
                In  What Are Some Different Types of Stem Cells?, we saw how stem cells form the basic building materials for the human body. This makes them good candidates for restoring tissues that have been damaged by injury or disease.
                For decades, researchers have been studying the biology  of stem cells to figure out  how development works and to find new ways of treating health problems.
                How would stem cell therapy work?
                The goal of any stem cell therapy is to repair a damaged tissue that can’t heal itself.
                This might be accomplished by transplanting stem cells into the damaged area and directing them to grow new, healthy tissue.
                It may also be possible to coax stem cells already in the body to work overtime and produce new tissue.
                 To date, researchers have found more success with the first method stem cell transplants.
