Passage One

Andrea had never seen an old lady hitchhiking before. However, the weather and the coming darkness made her feel sorry for the lady. The old lady had some difficulty in climbing through the car door, and pushed her big brown canvas shopping bag down onto the floor under her feet. She said to Andrea, in a voice that was almost a whisper, "Thank you dear - I’m just going to Brock Bourne" Something in the way the lady spoke, and the way she never turned her head, made Andrea uneasy about this strange hitchhiker. She didn’t know why, but she felt instinctively that there was something wrong, something old, and something dangerous. But how could an old lady be dangerous It was absurd. Careful not to turn her head, Andrea look sideways at her passenger. She studied the hat, the dirty collar of the dress, the shapeless body, and the arms with their thick black hairs. Thick black hairs Hairy arms Andrea’s blood froze. This wasn’t a woman. It was a man. At first, she didn’t know what to do. Then suddenly, an idea came into her racing, terrified brain. Swinging the wheel suddenly, she threw the car into a skid, and brought it to a halt. "My god!" she shouted. "A child! Did you see the child I think I hit her. " The "old lady" was clearly shaken by the sudden skid. "I didn’t see anything dear," she said. "I don’t think you hit anything. " "I am sure it was a child!" insisted Andrea. "Could you just get out and have a look Just see if there is anything on the road" she held her breath. Would her plan work It did. The passenger slowly climbed out to investigate. As soon as in front of her vehicle, Andrea gunned the engine and accelerated madly away, and soon she had put a good three miles between herself and the awful hitchhiker. It was only then that she thought about the bag lying on the floor in front of her. Maybe the bag would provide some information about the real identity about the man. Pulling into the side of the road, Andrea opened the heavy bag curiously. It contained only one item — a small hand axe, with a razor-sharp blade. The axe, and the inside of the bag, were covered with the dark red stains of dried blood. Andrea began to scream.

Andrea allowed the hitchhiker to take a ride in her car, mainly because ______.

A．the hitchhiker was an old woman

B．she was curious about the old lady

C．the lady had a heavy bag

D．she knew the old lady

池中水深2.5m，月球到水面距离是3.84×10⁸m，池边的人看到池中月亮的像，则人看到的像是______（“实”或“虚”），距水面______m．

阅读以下文字，完成下列问题。

有一种理论认为，证券市场在走向成熟时会使市场参与者的赢利趋向平均化，但是我们知道几乎国内外所有证券市场的价格都存在一定程度的扭曲。如果用更通俗的语言来表述，就是市场永远不会走到真正成熟的那一天，股票价格的定位根本不能用所谓理性的计算来获得。所以，我们将无法界定绩优股与垃圾股在价格和投资价值上的差异，也几乎不能清除那些为了获得超额利润而大肆造假的上市公司。就算是已经发展了一百多年的美国证券市场，不也冒出了诸如“安龙”“世界电脑”之类的丑闻。
但是在美国，对造假行为的打击是______的，我们几乎可以用“残酷”这个词来形容。通常情况下，这些造假公司的首脑和相关人员都会______并过上长期的铁窗生活，而且不会有______的机会。或许这就是真正意义的成熟市场，承认价格的扭曲，承认所有的投资者都是为了利益而来，也承认有可能存在虚构利润伪造报表的上市公司，但与此同时法律以极度严厉的惩罚制度威慑着违法者。从这个角度讲，假如我们都理解了“对造假者的仁慈就是对投资者的犯罪”的含义，也许我们的市场就离成熟不远了。
中国经济发展到目前这个阶段，向消费型经济的转型是必由之路，启动社会需求对经济拉动的杠杆作用将会是下一个经济周期的主要动力。在过去的10年里，制造类上市公司的辉煌是伴随着中国成为“世界工厂”的步伐成长起来的。在未来的10年甚至更远的时间里，随着国民生活质量和水准的提高以及对消费需求的进一步上升，我们有理由相信一些正在不断壮大的消费类品牌将会步入上升轨道。

以下对文章内容推断不正确的一项是______。

A．造假行为人人喊打，但如果不予以彻底的打击，在一定条件下，它还会死灰复燃
B．终止来料加工型经济，刺激消费，扩大内需，是中国下一个经济周期的主要任务
C．“使参与者的赢利趋向平均化”是理想化的理论，很难指导中国证券市场走向成熟
D．中国的证券市场，如果能承认价格的扭曲，严厉打击造假现象，那就离成熟不远了
