   In the West, some people believe that personality can be predicted according to the time of the year the person was bor. From China comes the belief that the year of birth influences one's personality. In the past century, a new belief ahs arisen: the idea that personality is related to one's ABO blood type. People with blood type A, for example, are considered more likely to be serious, hard-working, and quiet, while people with blood type O are likely to be popular and outgoing, yet often unable to finish what they start. Though this belief continues to be strong, some people question whether it is true.
   The blood-type personality theory(理论) started in Japan in 1927 when Furukawa Takehi noticed personality similarities and differences among his workers. This idea soon went out of fashion, but was brought back by a Japanese television host named Toshitaka Nomi in the 1970s. The belief is still strong in Japan and is increasingly popular in neighboring countries. Some young Koreans have taken to the theory. A recent study showed 76 percent of Koreans aged between13 and 64 believing in the blood-type personality connection. Though most Asians might believe in the blood-type theory, for many it seems harmless and not something to be taken too seriously.
   Is the belief true? The scientists in Asia largely dismiss the belief as a modern-day superstition(迷信). Most studies have failed to find any strong connection between blood and personality. Generally, scientists warn against making predictions or important decisions based on this questionable theory.

下列叙述不正确的是:
A.液氯泄漏事故时,附近人员应迅速远离液氯泄漏地点,并逆风往安全区域疏散
B.水的沸点比硫化氢高,主要原因是水分子间能形成氢键
C.反应AgCl+NaBr=AgBr+NaCl能在水溶液中进行,是因为AgBr比AgCl更难溶于水
D.常温下浓硫酸可贮存于铁制或铝制容器中,说明常温下铁和铝与浓硫酸不反应
