Antifreeze is a liquid(液体) that is added to water to keep it from freezing． When water freezes and turns to ice，it expands(膨胀)．The force of water expanding is so great that it will break the hardest metal．Water is used in car engines(发动机) to keep them cool while they run，and if this water is allowed to freeze in winter it can break the iron block of the engine．That is why antifreeze is necessary．
Water freezes at 0℃；the usual kind of antifreeze will not freeze until the temperature is－40℃．A mixture(混合物) of five parts of water and four parts of antifreeze will prevent freezing at－18℃；four parts of water and five parts of antifreeze reduce this to －22℃．
Alcohol is a kind of good antifreeze，but when the air is running it becomes hot and the alcohol boils away，so it must be changed very often．Most people use antifreeze that does not boil away when the engine is running．There are several chemicals that do this．One of the most popular is called ethylene glycol．people use ________ to keep car engines cool．
| A．antifreeze | B．water | C．alcohol | D．ethylene glycol. |

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 think the belief as a modern-day superstition(迷信). Most studies have failed to find any strong connection between blood and personality. Generally, scientists are against making predictions or important decisions based on this questionable theory.The writer uses blood type A and O as an example to explain ________.
| A．the difference between the two blood types |
| B．the relationship between the two blood types |
| C．the influence of blood type on one’s behavior |
| D．the connection between personality and blood type |
