(每空1分,)如图甲表示某生物膜结构,图中A、B、C、D、E、F表示某些物质,a、b、c、d表示物质跨膜运输方式。图乙和图丙表示物质运输曲线,请据图回答:

(1)A代表        分子,B代表           ,D代表           ;
(2)动物细胞吸水膨胀时B的厚度变小,说明B具有                 。
(3)维生素D和葡萄糖从肠腔进入小肠上皮细胞的过程分别是图中编号          。
(4)若图甲是癌细胞的细胞膜,则膜上含量较正常细胞减小的物质是[   ]        。
(5)若图中是线粒体膜,b和c过程运输的气体分别是          。b、c运输方式符号图         所表示的物质运输曲线。
(6)若图甲表示人体红细胞膜,则表示Na+、K+运输的分别是图中        。Na+、K+的运输方式符合图中          所示曲线。
(7)已知红细胞吸收葡萄糖是协助扩散,而有人认为小肠上皮细胞以主动运输的方式吸收葡萄糖,请设计实验加以确定。
①实验步骤:
第一步:取甲、乙两组生长状况相同的小肠上皮细胞,放入适宜浓度的含有葡萄糖的培养液中。
第二步:甲组细胞给予正常的呼吸条件,                                。
第三步:                                                            。
②预测实验结果并分析:
a.若甲、乙两组细胞对葡萄糖的吸收速率基本相同,则                   。
b.                                                                 。

Who Is Fooled?

  Just as the teacher was coming into the classroom, one of the boys, whose name was James, said loudly, “Teacher is a fool.” The teacher pretended not to have heard this.He went up to the platform and said,“ Today we are going to have a lesson on punctuation.Punctuation in a sentence is very important.Look at this sentence.” He picked up a piece of chalk and wrote the following sentence on the blackboard:James says the teacher is a fool.The class laughed.“Now,” continued the teacher, “with two commas I can change the meaning of the sentence entirely.” He then put in two commas and the sentence read:

  James, says the teacher, is a fool.

  Notes:

  1.fool V.愚弄;玩弄,标题中的be fooled是被动语态。n.愚人;傻瓜

  2.whose的先行词是one of the boys,由whose引出的从句,其前后均有逗点,是非限制性定语从句。

  3.pretend v.伪装;假装,其后接动词不定式。在句中它后面接not to have heard,表示:老师假装没听见。

  4.platform n.讲台

  5.punctuation n.标点;标点使用法,a lesson on punctuation是关于标点使用法的课,这里的on相当于介词about.

  6.comma n.逗点,entirely adv.完全地。全句可译作:我用两个逗点就能完全改变这话的意思。

  7.read在这里是过去时,它的意思是:读作:改为。
