伪劣汽车配件英文缩写怎么说不是我想要的答案，但是也谢谢你们2个了，字写得多些的那个，GOODFRANK同样谢谢你啊

The socialist market-oriented economy in our country is developing rapidly like a truck running at a high speed. In the meantime, the general public is surprised to find that there are more and more fake and inferior products seriously hampering the expansion of our market economy.
There is no doubt that fake and inferior products are extremely harmful. In the first place, they endanger people's health, giving rise to a lot of injury accidents. Secondly, fake and inferior products are usually sold on the cheap. In many cases they interfere with the normal economic order in our country, affecting the marketing of many high-quality goods. This, in a great degree, hinders the development of our socialist market economy and harms the interests of our state. Therefore, we can say that fake and inferior products are the most dangerous pests in our healthy economy, which must be cut away as soon as possible.
In my opinion, several strong measures should be adopted to fight against fake and inferior products. On one hand, those who make them deserve to be severely punished by the law. On the other hand, consumers should learn to discern between true and false. Only in this way can they defend their own legal rights and interests.

解题思路：本题考查学生对物理变化和化学变化的确定．判断一个变化是物理变化还是化学变化，要依据在变化过程中有没有生成其他物质，生成其他物质的是化学变化，没有生成其他物质的是物理变化．

A、用工业酒精和水兑制成“假酒”就是水和工业酒精的简单混合，没有新的物质生成，属于物理变化，故A错；
B、用淀粉、蔗糖、奶香精等掺和成“假奶粉”只是淀粉、蔗糖、奶香精的简单混合，没有新的物质生成，属于物理变化，故B错；
C、用色素、水、食盐等兑制成“假酱油”只是混合物的简单混合，没有新的物质生成，属于物理变化，故C错；
D、硫黄燃烧生成二氧化硫，有新的物质生成，属于化学变化，故D正确．
故选D．

点评：
本题考点： 化学变化和物理变化的判别．

考点点评： 要熟记物理变化与化学变化的本质区别：是否有新物质生成，有新物质生成属于化学变化，没有新物质生成属于物理变化．
