　　例1(2006年真題)

　　He visited the casino, lost the $20 and left. On his second visit he lost $800. The casino issued to him, as a good customer, a "Fun Card", which when used in the casino earns points for meals and drinks, and enables the casino to track the user's gambling activities. For Williams, these activities become what he calls electronic morphine.

　　41 In 1997 he lost $21,000 to one slot machine in two days. In March 1997 he lost $72,186. He sometimes played two slot machines at a time, all night, until the boat docked at 5 a.m., then went back aboard when the casino opened at 9 a.m. Now he is suing the casino, charging that it should have refused his patronage because it knew he was addicted. It did know he had a problem.

　　[A] Although no such evidence was presented, the casino's marketing department continued to pepper him with mailings. And he entered the casino and used his Fun Card without being detected.

　　[B] It is unclear what luring was required, given his compulsive behavior. And in what sense was his will operative?

　　[C] By the time he had lost $5,000 he said to himself that if he could get back to even, he would quit. One night he won $5,500, but he did not quit.

　　[D] Gambling has been a common feature of American life forever, but for a long time it was broadly considered a sin, or a social disease. Now it is a social policy: the most important and aggressive promoter of gambling in America is government.

　　[E] David Williams's suit should trouble this gambling nation. But don't bet on it.

　　[F] It is worrisome that society is medicalizing more and more behavioral problems, often defining as addictions what earlier, sterner generations explained as weakness of will.

　　[G] The anonymous, lonely, undistracted nature of online gambling is especially conductive to compulsive behavior. But even if the government knew how to move against Internet gambling, what would be its grounds for doing so?

　　【解析】[C]從前后文表達(dá)的語義來看，前文的第一句話表明了本段的主題He visited the casino, lost the $20 and left。試題后面的句子是In 1997 he lost $21,000 to one slot machine in two days，兩者的側(cè)重點(diǎn)都集中在lost(輸錢)上，同是前后文中都出現(xiàn)了一些數(shù)字加以說明，因此從語義上判斷，要填入的內(nèi)容一定和此人輸錢有關(guān)，同時選項(xiàng)中很可能會出現(xiàn)數(shù)字。對比選項(xiàng)，選項(xiàng)[C]中出現(xiàn)了$5,000和$5，500和前后文的數(shù)字形成照應(yīng)，由于其他選項(xiàng)中沒有任何數(shù)字，考生應(yīng)該很快能看出這個答案。此外，從語義邏輯上看，試題所在的選項(xiàng)句和試題后面的一句其實(shí)是用具體的事實(shí)數(shù)據(jù)在描述David Williams的賭癮越來越大，兩者的語義邏輯表達(dá)方向一致，因此選項(xiàng)[C]是正確答案。
