2-- Of course. I will check it for you at once.

1-- My car won't start; I don't know why；it just won't crank up.

2-- There is hardly any water in the radiator. It's dangerous, sir! You could break down because of the heat, you know.

1-- Please fill it up with water, then. Could you check my tyres, too? I think they need air.

2-- No problem, sir. Should I check the air in the spare tyre as well?

1-- I don't think so. It's brand-new.

2-- Shall I clean the wind shield for you?

1-- Yes. You had better make the car start after you do it. I'm afraid it still can't start.

2-- OK. I promise you that it will be OK.

1--打扰一下，我的车出毛病了。你能帮我检查一下吗？

2--当然可以。我马上帮你检查一下。

1--我的车发动不了，我不知道为什么，它就是发动不起来。

2--水箱面没有水了。先生，这很危险的。你该知道它会因为过热而损坏的。

1--那就加点水吧。你能帮我也检查一下轮胎吗？我想轮胎需要充气了。

2--没问题，先生。还要找帮你检查下备用胎吗？

1--我觉得没必要，备用胎是全新的。

2--还要我给你清洁一下挡风玻璃吗？

1--好的，在你清洁完后最好帮我发动一下汽车，我担心仍发动不起来。

2--好的。我保证汽车没问题。
