澳大利亚莫纳什大学的研究人员发现了肥胖引发Ⅱ型糖尿病的机制:脂肪细胞会向血液中释放一种名为色素上皮衍生因子(PEDF)的蛋白质,这种蛋白质能导致肌肉和肝脏对胰岛素不再敏感,因此胰腺只能靠生产更多的胰岛素来抵消由此带来的负面影响.图1,图2分别表示人体内血糖调节的图解过程和Ⅰ激素发挥作用的一种机制.图中Ⅰ、Ⅱ、Ⅲ表示参与血糖调节的激素.下列叙述正确的是(    )

A:Ⅱ激素能促进血糖进入组织细胞

B:Ⅰ、Ⅱ激素间存在协同作用又有拮抗作用

C:Ⅲ激素分泌增加可促进肝糖原的合成

D:Ⅱ型糖尿病人的胰岛素含量并不低,病因可能是PEDF降低了细胞膜上受体的敏感性

    Women make better drivers than men for many reasons. Why is that, do you suppose? Wouldn't you think that competing at who has better driving abilities is pointless? If you ask me, I'd like to say, men know that women are better drivers but do not have the courage to admit the truth—women are queens of the road.

    Unlike men, women stop for directions when they have no idea as to where they are going. We don't drive around for hours pointlessly wasting a tank of gas only to find ourselves heading in the wrong direction. Have you ever in a car with a man who is lost? He tells you to shut up when you begin to open your mouth. And every five minutes or so he takes a tum going forty-five miles per hour only to find out he's made another wrong turn.

    Speeding is what men do best on the road. Traffic is not a race. There is a reason why men get more speeding tickets than women. Not because we trick to get out of tickets but only because we don't get pulled over as frequently. We don't speed. We have more intelligence than senselessly to put our own lives as well as the lives of others in danger.

    My largest issue with male drivers is how a majority of them drive with one hand on the wheel and the other hand doing only God knows what. The seat is backed as far as possible, and they're totally lost into loud music beyond a necessary level. You don't ever see women driving like that.

    I feel that the above evidence more than proves my points that women are not only better drivers but also safer drivers than men. We women rule the road. Oh, and men, if you want to continue criticizing women for being bad drivers, bring it on. We know you lack confidence, or else you wouldn't be wasting your valuable time making jokes about the ones you may choose to spend the rest of your days with.
