关于诗歌《峨眉山月歌》,理解不正确的是()

A.“仗剑去国,辞亲远游”的青年,乍离乡土,对故国故人不免恋恋不舍。江行见月,如见故人。然明月毕竟不是故人,于是只能“仰头看明月,寄情千里光”了。末句“思君不见下渝州”依依惜别的无限情思,可谓语短情长。

B.诗中连用了五个地名,构思精巧,不着痕迹,诗人依次经过的地点是:峨眉山──平羌江──清溪──三峡──渝州,诗境就这样渐次为读者展开了一幅千里蜀江行旅图。连用五个地名,精巧地点出行程,既有“仗剑去国,辞亲远游”的豪迈,也有思乡的情怀,语言流转自然,恰似“清水出芙蓉,天然去雕饰”。

C.除“峨眉山月”以外,诗歌处处写景,;除“思君”二字,没有更多的抒情。然而“峨眉山月”这一集中的艺术形象贯串整个诗境,成为诗情的触媒。

D.诗歌中,山月与人万里相随,夜夜可见,使“思君不见”的感慨愈加深沉。明月可亲而不可近,可望而不可接,更是思友之情的象征。凡咏月处,皆抒发江行思友之情,令人陶醉。

It was two years ago today that the hunting ban came into force, supposedly ending centuries of tradition. However, the law has been an unmitigated failure—not that either side is shouting about it.

It was a nightmare vision that struck fear and loathing into the hearts of millions. When the hunting ban became law, it was said, 16,000 people would lose their jobs, thousands of hounds would be put down, rotting carcasses would litter the countryside, hedgerows would disappear, riders would face on-the-spot fines, law-abiding people from doctors to barristers would be dragged from their horses and carted off to prison, while dog owners would be prosecuted if their mutt caught a rabbit.

These were just some of the claims as desperate countryside campaigners battled to save their sport in the lead—up to the hunting ban, which Labour rammed into law using the Parliament Act on November 18, 2004.

For many, the fears were real. Others exaggerated as they fought an increasingly aggressive anti-hunting lobby which had rejected acres of independent evidence affirming that hunting is the most humane way of killing foxes. In the battle to "fight prejudice, fight the ban", every emotive argument was deployed.

For its part, the anti-hunting brigade extravagantly claimed that the ban would put an end to the rich parading in red jackets. A senior Labour MP, Peter Bradley, admitted in this newspaper that it was, as many suspected, about "class war" . He lost his seat shortly afterwards. But people in red coats did not disappear.

In fact, none of the forecasts came true. What did happen was something nobody had predicted, the spectacular revival and growth of hunting with hounds. In short, the hunting ban has been a failure.

Today, on the second anniversary of the ban’s coming into force on February 18, 2005, new figures show that participation in the sport has never been higher. It is so cheerful that two new packs have been formed, something that has not happened for centuries.

They include the seductively named Private Pack, set up by the financier Roddy Fleming in Gloucestershire. It operates on an invitation-only basis, a sort of hunting private members’club. This can only mean one thing: like it or not, hunting is cool. Young people are taking it up, enticed by the element of rebellion and the mystique of what actually happens as hunts attempt to keep within the law.

What does the author think of the hunting campaigners’position().

A. It was unknowingly biased.

B. It was emotionally charged.

C. It was increasingly militant.

D. It was certainly powerful.
