CRI听力:F1: Spanish Grand Prix Preview

The Formula One World Championship heads to Barcelona this weekend for the Spanish Grand Prix.

Defending champion and Mercedes driver, Lewis Hamilton, will again be the man to beat at in Barcelona.

But fellow Mercedes driver German driver Nico Rosberg is looking to eclipse his team-mate.

Rosberg, last year's runner-up behind Hamilton, finished top in just one of his past 15 races and has failed to take pole position in four races this season.

Trailing Hamilton in second by 27 points, Rosberg says now is the time to pull ahead:

"It's just a matter of maximising the weekends now, it's not really come together until now. Parts have gone well, then other parts not so well. So I need to put it all together, of course I'll try to do that from here onwards."

This year's championship is more open, with Sebastian Vettel confirming Ferrari's return to form and shaping up as a genuine title contender.

However, the four-time world champion needs to improve on his performance in Bahrain, where he finished fifth after sustaining a front wing problem.
