问题 What does the speaker feel about summer pictures?
  
In any movie theater any summer, you can practically hear the atrophying of brain cells. Summer pictures don’t insult the audience’s intelligence so much as they ignore it, playing instead to the mass-market inner child.But with most big films serving as a form of pop-cultural potty training, there’s a grand void to be filled for viewers who have not sent their brains to summer camp—who want the occasional film to speak to their inner grownup.
Human cloning involves creating an embryo out of a cell taken from a fully developed human being. "Reproductive" cloning means growing an embryo into a second, genetically identical human being. "Therapeutic" cloning, by contrast, means using an embryo as a source of stem cells for the person who supplied the originally cell. The theory is that stem cells with DNA identical to yours would be more likely to develop successfully into replacement parts for you. Brain cells for people with Parkinson’s are the most promising example, but ultimately even severed limbs might grow back this way.

选项 A、Therapeutic cloning is used mainly for research purposes and therefore should be allowed to continue.
B、Therapeutic cloning is used for medical purposes and not for reproducing full human beings.
C、Therapeutic cloning is used for replacing the diseased parts of human organs.
D、Brain cell can be used in the future to cure the Parkinson’s disease.

答案A

解析 抓住原文中的关键词作出正确的推断,如therapeutic(治疗的)与选项A中research(研究)意思相左。
