如果是独立问句,句型应该是 What is it like to do / be .
is it 调换成 it is (it's) 的情况,通常是跟着 "Can you tell me" 或 "Do you know" 后面,所以才把疑问句型改为陈述句型.
意思当然不变,是“ 做.会是什么样的（感觉）”
例如：
Can you tell me what it's like to be a professional athlete?
你能告诉我作为职业运动员是怎样一种感觉吗?
Can you tell me what it's like to go on a blind date?
你能告诉我和一个从未见过的陌生人约会是种什么样的感觉吗?
