sorry i am late again, i had a flat tyre on the way.
很抱歉又迟到了,在路上我的轮胎跑气了。
a flat tyre 10 miles beyond mount barnett roadhouse, a cross-threaded wheel nut, a dodgy jack handle, a dubious spare and a temperature of 100f (38c) had made for a taxing last couple of hours.
so, when they went to the test, they decided to tell the professor that their car had broken down the night before due to a very flat tyre and they needed a bit more time to study.
