或者说,我们愿意把他看作是灰色的。

但是,没有人会喜欢只有灰色的世界。

__________。

这也就是和谐。

(易中天《灰色的孔子和多彩的世界》)①这世界充满生命活力,姹紫嫣红,千姿百态,万类霜天竞自由。

②灰色也只有在和其他色彩搭配时,才能显示它的普适性,显示它的高贵和纯粹。

③也正因为有了思想的高贵纯粹,纷繁的世界才不至于俗不可耐。

④灰色提升着品位,而多彩保证了活力。

⑤因此,灰色的孔子又必须链接多彩的世界。

⑥正因为有了生活的五彩缤纷,理论的灰色才不显得死寂。

A.①⑥②⑤③④ B.②⑤①⑥③④C.②①⑤④⑥③ D.①②⑤④⑥③【正确答案】B讲解:语句之间的衔接连贯,应该注意以下几点:话题一致,叙述角度一致,句式合理,陈述对象一致,感情色彩一致,前后照应,总提与分承照应,音节和谐,符合事理。

本部分讲的是色彩的和谐,注意形象到理论、自然到人文的顺序。

定义从句中只有whose表示谁的。

选D第6题:细胞的骨骼细胞也有骨骼,但它们不像人的骨骼一样是由钙构成的。

生物学家将这些细胞骨骼称为细胞骨架,它是由蛋白质分子形成的链条状骨架。

细胞骨架可以使细胞成形,帮助细胞移动。

像斯奈尔森的雕像一样,细胞骨架的结构没有固定的尺寸。

当外界压力作用于这些细胞骨架时,可以将它们压缩。

在针塔里,金属丝传送电压,杆子承受压力。

在一个细胞骨架中,替代金属丝和杆的是蛋白质链,它们有的薄,有的厚,还有的空。

它们连接在一起形成了一个稳定但是灵活的结构。

美国宇航局对细胞骨架发生了兴趣,是因为细胞骨架可以对重力产生反应。

重量可以对细胞骨架施加压力,将它压缩。

当重力消失的时候(例如在太空飞行的时候)会出现什么样的变化呢?当细胞骨架《放松》时,细胞的行为会出现不同吗?这都是美国航天局的科学家们想知道的事。

美国哈佛大学细胞生物学家因博先生是致力于这方面研究工作的负责人。

因博解释说:《重力或任何外力作用于细胞膜,细胞骨架可以通过特殊的蛋白质(例如整联蛋白)来察觉这些力的作用。

》在细胞里整联蛋白钩住细胞骨架。

因博和他的同事通过实验发现当整联蛋白移动时,细胞骨架变硬了。

他们的实验过程如下:将细小的、大约只有1-10微米的磁性水珠涂到并凝固在整联蛋白的特殊分子上,然户将它们放在一个磁场里。

在磁场的作用下,磁性水珠开始旋转,试图指向磁场,就好像一个罗盘指针指向地球磁场一样。

水珠使整联蛋白滚动,接着拧动细胞骨架,使细胞骨架发生移动,结果细胞骨架变硬了。

如果细胞骨架受到更重的压力,它会变得更加坚硬。

拖拉整联蛋白不仅可以使细胞骨架变硬,也可以激活一定数量的基因。

《激活一个基因》意味着诱使一个基因产生核糖核酸和蛋白质。

那时非常重要的,因为蛋白质是一些给细胞发信息、通知细胞采取行动的小信使。

采用这种方法,似乎可以使细胞在不同的遗传因子中转换。

在进行磁性水珠实验前,哈佛大学的因博研究组就已经发现细胞几何学和细胞行为之间的联系。

扁平的细胞有一副紧绷的细胞骨架,不知为什么它可以感觉到人体到底需要多少这样的细胞,它可以根据人体的需要来调节自己:保护或繁殖自己,或者将自己杀死。

例如,人体的红细胞就是一种扁平的细胞,当体内的红细胞过少时,体内可以通过一种促红细胞生长素,促使骨髓生出更多的红细胞;当体内红细胞过多时,一些扁平形状的红细胞就变成其他形状的红细胞——球形、镰刀形、刺猬形等,这些形状的红细胞变形能力很差,它们在体内循环时不能通过比自己还细的毛细血管,于是在血流切应力的作用下发生破裂而死亡,或者被脾脏认为是异类细胞而被扣留、吞噬,最终导致体内红细胞减少。

从原文看,下列对《细胞的骨骼》的说明,不正确的一项是()A.它是由蛋白质分子形成的链条状骨架,重力可以将它压缩。

B.它是一个稳定但是灵活的结构,可以使细胞成形,帮助细胞移动。

C.它的结构没有固定的尺寸,当重力消失的时候,细胞骨架会变硬。

D.当重力或任何外力作用于细胞膜时,它可以通过特殊的蛋白质来察觉这些力的作用。

【正确答案】C讲解:情况刚好相反,受到压力才会变硬第7题: Passage C Passing through the Atlanta airport one morning, I caught one of those trains that take travelers to their boarding gates. The free trainsrun back and forth(来回)all day long. Not many people consider them fun, but I heard laughter(笑声). At the front of the first car were a man and his son who was about five years old. 《Here we go! Hold on to me tight(紧紧地)!》 the father said. 《Look out there! See that pilot? I bet(打赌)his walking to his plane.》 The son stretched (伸出)his neck to look. As I got off, I remembered something I'd wanted to buy. I was early for my flight, so I decided to go back. I did and just as I was about to go back to the train for my gate, I saw that the man and his son had returned, too. 《I want to ride some more!》《More?》 the father asked, 《You're not tired?》《It is fun!》 his son answered. 《All right,》 the father replied, and when a door opened we all got on. I realized that the father and his son were just riding this shuttle together, making it exciting, sharing each other's company(陪伴). There are parents who can afford to send their children to Europe or Disneyland, but the children turnout rotten(被宠坏). There are parents who live in million-dollar houses and give their children cars and swimming pools, but something goes wrong. Why? The answer is so simple: parents who care enough to spend time, to pay attention andto try their best. It doesn't cost a cent(美分), but it is the most valuablething in the world.The story probably happen .A. at the airport.B. at the supermarket.C. at the ticket office.D. at the bus station.【正确答案】A讲解:Passing through the Atlanta airport one morning, I caught one of thosetrains that take travelers to their boarding gates.选A第8题:(A)It's important (B)of (C)us (D)to protect our environment.【正确答案】B讲解:B. of改为for .形容词important用来修饰protect our environment,所以要用for.如果形容词修饰人要用of第9题:Doing sports can give body some_________(积极的) exercises after you sitin the office the whole day.A.inactiveB.passiveC.activeD.creative【正确答案】C讲解:A.懒散的 B.消极的 C.积极的 D.创造性的第10题:If you want to learn about computers and the same time you want toimprove your typing, how much will you pay for it?A.$75.B.$150.C.$235D.$250【正确答案】C讲解:同时学习电脑和打字,需要花费75+10+125+25=235选C第11题:The reason _____ he was late was _____he missed the bus.A. that; thatB. that; whichC. why; thatD. which; that【正确答案】C讲解:【解析】考查定语从句和表语从句,第一空后是要定语从句,the reason 为先行词,在从句中作状语,表原因,故用why。
