The best way of learning a language is using it .The best way of learning English is talking in English as much as possible. Sometimes you'll get your words mixed up ( 混合)and people will not understand you .Sometimes people will say things too quickly and you can't understand them. But if you keep your sense of humor (幽默感),you can always have a good laugh at the mistakes you make(你所犯的错误). Don't be unhappy if people seem to be laughing at your mistakes（错误）. It is better for people to laugh at your mistakes than to be angry with you. because they don't understand what you are saying .The most important thing for learning English is : “Don't be afraid of making mistakes because everyone makes mistakes. ”

研究者将乳腺细胞M诱导成为乳腺癌细胞（记为M^c），研究细胞癌变后的代谢水平变化．

（1）细胞癌变后，细胞表面的____ 减少，使细胞粘着性降低，但增加了一些癌细胞特有的蛋白成分，所以可用____ 的方法来鉴定细胞是否癌变．

（2）实验一：研究者测定了M及M^c的葡萄糖摄取量，结果如图1．由图可知，M^c对葡萄糖的摄取量大约是M的____ 倍．

（3）实验二：研究者将一种作用于线粒体内膜的呼吸抑制剂加入到M和M^c细胞的培养液中，与____ 细胞相比，计算获得图2所示数据．结果说明　____ 对该抑制剂更为敏感．由于该抑制剂抑制____ 阶段，为确定癌变细胞的呼吸方式，研究者测定了乳酸在细胞培养液中的含量，发现M^c组的乳酸含量明显升高，可确定____ 

（4）为了探究癌细胞发生这一代谢变化的原因，研究者测定了M和M^c中某种葡萄糖转运蛋白mRNA的量，结果见图3，这说明癌细胞通过____ 来提高葡萄糖摄取量．
