Taiwan-born American director Ang Lee's win of his second directing Oscar has sparked complex feelings among Chinese audiences, who expressed their pride due to the director's Chinese roots, but couldn't help but reflect on why the Chinese mainland has failed to deliver more outstanding films to the world .

Lee, 58, on Sunday accepted the Academy Award for best director for Life of Pi, a 3D adventure-drama film.Lee had won the top directing award in 2006 for Brokeback Mountain and the best foreign language film Oscar in 2001 for Crouching Tiger, Hidden Dragon.

Lee came to Hollywood's attention after directing three Chinese-language films in the early 1990s, with an emphasis on the interactions between modernity and Chinese traditions.Some Web users called Lee "a source of pride for Chinese people," and admired him for bearing the torch of Chinese culture.

However, a large number of audience members and critics from the mainland expressed their frustrations over home-made movies: Mainland filmmakers have made numerous ambitious tries for the prestigious award but never won.

Hao Jie, a young director whose 2010 film Single Man won the Special Jury Prize in the Tokyo Filmex Festival but was never screened in the mainland for it showed complex sex lives in a village.

"Due to the censorship(审查), we are prevented from the beginning of our production, which forbids our works from mirroring realities," Hao said.

While acknowledging the system's role in undermining(削弱) excellent works, Su Mu, a well-known film critic, argued that the atmosphere in the mainland's film circle is also to blame."Lee produces his works with his heart, but most mainland directors now only have money in mind."

Though having obtained approval for his second film from the film authority, Hao said cinemas have kept delaying the screening of his work."This is another factor that prevents us from progressing. Cinemas won't risk showing our film, which features no stars and is considered non-mainstream," complained Hao.

(15分)在研究摩擦力特点的实验中,将木块放在水平长木板上,如图17甲所示,用力沿水平方向拉木块,拉力从0开始逐渐增大.分别用力传感器采集拉力和木块受到的摩擦力,并用计算机绘制出摩擦力Ff随拉力F变化的图象,如图乙所示.已知木块质量为0.78 kg,重力加速度g取10 m/s2,sin37°=0.60,cos37°=0.80.

(1)求木块与长木板间的动摩擦因数;

(2)若将实验中的长木板与水平方向成θ=37°角放置,将木块置于其上,在平行于木板的恒定拉力F作用下,以a=2.0 m/s2的加速度从静止开始向上做匀变速直线运动,如图丙所示.求拉力应为多大?
