To interfere, to slow something down or make worse by getting in the way.干涉；妨碍；打扰

Having too many meetings is interfering with our work.

I told her to leave us alone and not interfere our problems.

(We can't finish the project on time if she continues to interfere by asking too many questions.)

To reflect, to think about or consider something, or to throw back a image as from a mirror.

Before I make a decision, I'd like some time to reflect.

When you look into a mirror, your image is reflected back to you.

(When I reflect on something, I look at it again and again in my mind and try to see all sides of it.)

To influence, to have an effect on something.

I think she can help us influence the others.

I don't think we can influence the final result.

They don't care what we think, so it'll be difficult to influence their decision.

(There's nothing we can do to influence the result because they don't care about anything except money.)

To focus, to bring attention to something and make it clear.

If we don't focus on something, we won't get anything done.

We aren't sure what to focus on, so everyone is confused.

(It's important to focus, but you have to be careful not to get lost in details.)

To exaggerate, to describe something as larger or more important than it really is.

It's difficult to believe what he says because he always exaggerates.

She said she could sell anything but of course that was an exaggeration.

(She said she was fluent in English, but she was exaggerating, so it's no surprise that she make so many mistakes.)

(I'm afraid this terrible news may influence their decision to support us.)

(If things are unclear and confusing, we need to focus on something and get organized.)

(All that noise is interfering with my ability to think.)

(After finishing the project, he looked back and reflected on what might have been done to make it better.)
