参考答案:A

完形填空

What do you do if you don't get into your first choice of university? That's the question      faces thousands of students in Britain every year.

Many students turn to Clearing, an education agency that helps      (find) university places for students at the last moment.       students don't have enough marks to get into their first choice of universities, Clearing tells them about places available at other universities, though they might have to study another subject.

But this year has seen a record number of students     want to study in universities. This means that there's been a fiecer competition for university places than usual. Education officials say six students competed for one place. It’s said almost 190,000 students still don't have a place in a university. That's a rise of over 46,000 students from last year.

       (face) with these numbers, some students are going to be disappointed, others might be thinking of an interesting choice: studying abroad. The University of Nottingham, for example, is offering places in Ningbo, near Shanghai.

                the problems with university entrance, the UK's Higher Education Minister, David Willetts, encourages students to study at home or to learn one kind of skills, such as cooking, hairdressing and so on .      some people say that rising university costs, less hope to find jobs in the future, and a drop in graduate recruitment(大学招生)mean it's      (bad) time to be a university student in the UK.
