Question

关于the的用法?
Busmen have decided to go on strike next week.The strike is due to begin on Tuesday.No one knows how long it will last.The busmen have stated that the strike will continue until general agreement is reached about pay and working conditions.Most people believe that the strike will last for at least a week.Many owners of private cars are going to offer 'free rides' to people on their way to work.This will relieve pressure on the trains to some extent.Meanwhile,a number of university students have volunteered to drive buses while the strike lasts.All the students are expert drivers,but before they drive any of the buses,they will have to pass a special test.The students are going to take the test in two days' time.Even so,people are going to find it difficult to get to work.But so far,the public has expressed its gratitude to the students in letters to the Press.Only one or two people have objected that the students will drive too fast!
这是新概念第84课的课文,有2处,都是关于the,大家帮我看看什么用法?
1.This will relieve pressure on the on the trains to some extent.
其中trains前为什么加the呢?不是复数前不用加吗?
2.All the students are expert drivers.也是为什么students前要加the呢?
