Hayley教口語，“死胡同”用英語怎么說？

When it comes to transportation, a dead end is a street that has no exit. This expression is also used for something that leads to no progress no success. If the police are investigating a crime and they come to a dead end, it means they do not succeed in solving the crime.

說到交通時(shí)，a dead end就是沒有出口的道路。同時(shí)這個(gè)表達(dá)也可以用來形容一件沒有辦法進(jìn)步或成功的事情。如果警察正在調(diào)查一項(xiàng)犯罪，而他們走到了a dead end，這意味著他們沒有成功地破案。

Even though your research appears to be at a dead end now, you shouldn't lose heartbut keep on trying.

即使你們的研究現(xiàn)在似乎沒有什么進(jìn)展，你們還是不應(yīng)該泄氣，而要繼續(xù)進(jìn)行下去。
