[单项选择]
When Abraham Lincoln was a lawyer in rural Illinois, he and a certain judge in town once got to bantering with one another about horse trading. The upshot of the discussion was that they agreed that the next morning, at nine o’clock, they would meet in front of the general store and make a trade. Each would bring a horse, unseen by anyone up to that hour. If either backed out of the deal, he would forfeit $ 25. The money from each man was held by the local banker.

The large crowd viewing the spectacle burst out laughing, already knowing that Abe Lincoln was bound to get the worst of the deal. A poorer horse just couldn’t exist anywhere and still be walking.

It is even harder for children to avoid second-hand smoke______(49)Research shows that children who are exposed to second-hand smoke are sick more often than children who live in homes where no one smokes and that the children of smokers are more than twice as likely to develop lung cancer when they are adults as are children of nonsmokers.The risk is even higher for children who live in homes where both parents smoke.
