人的书写习惯形成之后,具有在相当长的时间内保持相对不变的特性。这种相对稳定性是由条件反射的强度规律所决定的。因为一个人从学习和练习书写到书写动作定型的形成,一般都要经过较长的时间。在此时间内形成的条件反射的刺激次数和强度都在日益加大,从而使自动化锁链系统也就越加巩固,最终导致书写习惯的形成。这段话主要支持了这样一种论点,即( )。

It is not just Indian software and "business-process outsourcing" firms that are benefiting from the rise of the internet. Indian modern art is also on an upward spiral, driven by the aspirations of newly rich Indians, especially those living abroad, who use the internet to spot paintings and track prices at hundreds of gallery and auction websites. Prices have risen around 20-fold since 2000. particularly for prized names such as Tyeb Mehta and F.N. Souza.

There would have been "no chance" of that happening so fast without the internet, says Arun Vadehra, who runs a gallery in Delhi and is an adviser to Christie’s, an international auction house. He expects worldwide sales of Indian art, worth $ 200million last year, to double in 2006. It is still a tiny fraction of the $ 30 billion global art market, but is sizeable for an emerging market.

For newly rich--often very rich--non-resident Indians, expensive art is a badge of success in a foreign land." Who you are, and what you have, are on your walls," says Lavesh Jagasia, an art dealer in Mumbai. Indian art may also beat other forms of investment. A painting by Mr. Mehta that fetched $ 1.58 million last September would have gone for little more than $ 100 000 just four years ago. And a $ 22million art-investment fund launched in July by Osian’s, a big Indian auction house, has grown by 4.1% in its first two months.

Scant attention was paid to modern Indian art until the end of the 1990s. Then wealthy Indians, particularly those living abroad, began to take an interest. Dinesh Vazirani, who runs Saffronart, a leading Indian auction site, says 60% of his sales go to buyers overseas.

The focus now is on six auctions this month. Two took place in India last week; work by younger artists such as Surendran Naif and Shibu Natesan beat estimates by more than 70%. Sotheby’s and Christie’s have auctions in New York next week, each with a Tyeb Mehta that is expected to fetch more than $ 1 million. The real question is the fate of other works, including some by Mr. Souza with estimates of up to $ 600 000. If they do well, it will demonstrate that there is p demand and will pull up prices across the board. This looks like a market with a long way to run.

The author’ s narrative in the text centers on ()

A. the profits brought about by a pretty picture

B. why Indian modern art is booming

C. the Success of Indian software and "business-process outsourcing" firms

D. how wealthy Indians evaluate Indian modern art
