You're tutoring a child in math. You're giving him advice on how to answer multiple choice questions on a test. You say:
Try to narrow down your choices through process of elimination.
You're at a job interview and have been asked to described one of your weaknesses. You have to answer, but you want your answer to make you sound impressive. You want it to sound like this weakness is not really a problem. So you say:
If I HAD to pick something, I'd say it's that I have trouble saying "no" to people's requests.
You're making a short film. You placed an ad for an actor on a website, and got a lot of responses. Now you need to go through the responses, but that's going to take a long time. You want to get rid of some of them quickly. You tell your assistant director:
Let's just weed out the ones that don't have a photo attached.
You are at a video rental store with your children. You are getting several DVDs to watch over the weekend. You are going to let your children choose one DVD to watch. You say:
Pick out which one you want.
choices, phrasal verb You're a member of a band. You're telling someone the story of how you chose the name for you band. You spent a really long time trying to choose the best name. You describe this period:
We spent the first month just debating what to call ourselves.
choices, debate, discussion, gerund, time You are starting a band with a group of friends who are musicians. You're all sitting together and brainstorming ideas for band names. Your girlfriend sees you all sitting around and looking thoughtful, and asks what you're doing. You answer:
We're trying to come up with a name for our band.
To "come up with" an idea means to create it. You usually use "create" for physical things that you make, but you use "come up with ___" to describe creating an idea, a plan, a name, etc. Another example:
Where'd you come up with the idea to start a blog about English phrases?
Your first choice in this example might be "We're trying to come up with our band's name." But that isn't correct. Your band doesn't have a name yet, so you can't say "our band's name". You have to say "a band name" or "a name for our band".
This is a similar problem to sentences like "I'm going out to buy my swimsuit this afternoon." If you haven't bought the swimsuit yet, you can't call it "my swimsuit". You have to say:
I'm going out to buy a swimsuit.
choices, decision, progressive aspect You're a first-year college student and you haven't decided on your major (your area of study) yet. You are talking to a professor who asks what your major is. You want to tell her that you haven't decided yet, but you want it to sound like a positive thing. You say:
I'm keeping my options open.
