想请教你,第三段A对话里try and make,为什么不用try to make?还有第四段B对话
A:Is this your first time to set up for a trade show, David?
B:No. I attended the fair last year.
A:Other than selling interesting books, we have to try and make our booth stand out. That means we have to do something with this boring wall. B:That’s what the posters are for. I see they focus on the South East Asia region. And that ties into our drawing for a free trip to Thailand for two.
