1. Take a guess
單說Take a guess，英文里就是讓別人來猜猜看。你也可以把它用在你的回答中，表示只是一種猜測，別太當真就好。
例：If I had to take a guess, I'd say she's 30.
如果一定讓我猜的話，我覺得她得有30歲了。

2. At a guess
人家一開口，你聽到了at a guess，就知道對方是在猜測了。這個短語要表達的是“大約、估計”的意思。
例：At a guess, there were forty people at the party.
我猜，有40人參加了派對。

3. Chances are...
猜測總會有很多種可能，想要說出你認為的那種可能，就用Chances are來引導吧！
例：Chances are she has already heard the news.
我猜她八成已經聽說了。

4. (Right) off the top of one's head
不假思索，也不用知道太多，一個猜想就直接冒出來了，靈光乍現的趕腳，有木有？這時，你可以使用上面這個短語。
例：-How much do you think this car would be worth on a trade?
你覺得這車要是賣的話多少錢？
-Well, right off the top of my head, I'd say about a thousand.
呃... 我猜大概1000塊。

5. Shot in the dark
大黑天的亂放一槍，你擊中目標的可能性太小了。這個短語借此比喻碰運氣、是瞎猜噠！
例：We had nothing to go by. It was a shot in the dark, but it turned out right.
我們沒什么根據，不過是瞎猜，結果還猜對了。
