『壹』 (2013保定二模)如图是某家庭的遗传病的系谱,其中Ⅰ、Ⅱ、Ⅲ分别表示该家庭的第一、二、三代成员.该
(1)直系血亲是有直接血缘关系,即出生关系.包括生出自己的长辈(父母,祖父母,外祖父母以及更上的长辈)和自己生出来的晚辈(子女,孙子女,外孙子女以及更下的直接晚辈).旁系血亲是具有间接血缘关系的亲属,即非直系血亲而在血缘上和自己同出一源的亲属.因此Ⅲ-2与Ⅱ-1不是直系血亲,是旁系血亲.
(2)通常大写字母表示显性基因,小写字母表示隐性基因;该病为隐性遗传病,设该病由一对基因控制(A为显性基因,a为隐性基因).因此Ⅱ-1的基因组成是aa,一定有1个a来自Ⅰ-2,而Ⅰ-2是正常的,因此Ⅰ-2的基因组成是Aa;同理可知Ⅱ-3的基因组成是Aa.因此Ⅰ-2和Ⅱ-3的基因组成相同的

『肆』 2013初三石景山二模语文答案 不是百度文库里的 那不对 作文题好像是距离 很急!!!谢谢啦
距离
距离
抛开距离,让心再靠近一点。
雨在黑夜中尽情舞蹈,旋转,欢腾。我窝在家里,呆呆地看着电视屏幕。电视上反复都是些大众唱歌比赛,换汤不换药。煽情的手段一个比一个厉害,可是又有多少真实?
直到我看到他。
一双狰狞的眼睛,似乎不受人的控制。廉价的西装,残破的吉他,充满沟壑的脸庞。
一看就知道肯定是哪里来的乡下人,又在坚持不懈地追求梦想,电视台一贯的剧本。
可是我错了。
他是一位盲人,拿着微薄的薪水,勉强地撑起一个家,只为了儿子,来到这遥远的繁华。
“我不奢望我的儿子会为我感到骄傲,我只希望他不要为我而抬不起头,觉得和别的小孩有距离。所以我来到这里。”闷闷的声音,他的眼神变得柔和起来,很简短的一句话,却穿越了我与屏幕的距离,直插入心底,纯粹地连雨的声音也过滤了。如果这也是煽情,我愿深陷其中,因为有些爱是可以跨越时空的距离,传达到每一寸热土。
他轻轻地哼唱,每个音符都在跳跃,他紧紧地攥着儿子,空洞的眼神好像被填满。我诧异于他能准确无疑地摸索到儿子的位置,也许那浓郁的父爱能缩短他与儿子的距离,黑暗与光明的距离。两颗心没有了距离,紧紧地贴在一起。
原来爱可以超越一切距离。
明白那位盲人的不善言辞,因为每一位父亲都是默默地用弯曲的背撑起一片绿荫,呵护他们身下的花朵,直至灿烂了父亲的整个世界。
想想平时因为学习的压力大,整天对父亲大呼小叫,我如一个定时炸弹。不知不觉中,我和父亲有了些隔阂,一段距离,没有了以前的亲昵。想到这,一股酸楚涌上心头,却散不开,顶在喉咙,似乎是对我的惩罚。
明白生活中不可能没有距离,但我仍希望能与父亲的心相通。
第二天早上,我倒了一杯热茶给父亲,他眼睛里仿佛有什么一股光在跳跃,我怔怔地看着他一口气喝完茶,差点被烫到的好笑样子。那股酸楚扩散,化作淡淡的暖流,包围着我,让我逐步靠近父亲。原来小小的关心,能缩短长长的距离。
如果一个家遭遇了灾难,才能凸显亲情,那已经太晚了。在没有灾难的日子里,亲情的冷漠才是最大的灾难。
所以我们要抛开距离,不计较太多,才能使爱在生活中生根发芽,蔓延,长成一朵朵绚烂的温柔。
抛开距离,让爱在生命中温热。

Dear Sri/Madam, I read your advertisement on the Internet and I would like to apply for the position of a part-time tourist guide. I am a boy/girl of 18. I have a good knowledge of English and I’m excellent at speaking it, so there will be no trouble for me communicating with foreigners. What’s more, I know well about the famous national places of interest as well as the well-known resorts. Besides, I’m open-minded and it is easy for me to get along well with others. When tourists are in trouble I will be ready to help them. Thanks for your consideration. I would be more than happy to be employed. Looking forward to your reply. Yours, Li Hua
听力材料: Text 1 M: Jessie, what are you doing? W: I’m reading an interesting book about wild animals. M: Oh, I wonder if it is the same book I read last weekend. Text 2 W: Hello, is there a place I can use the Internet? M: Yes, indeed. There’s an Internet Café on the ground floor. They are $2 for ten minutes. Text 3 W: Your classmate Prince is excellent. He was first in the national maths competition. M: Yes, he’s very clever. But he is a person of few words. Text 4 M: What was it like working with those young girl stars? W: It was a great group. There were never any fights. We had a wonderful time. Text 5 M: It’s that time of the month again — time to pay the rent. W: Yeah, and I’m really broken now. M: Well, you need to tighten your belt just like me. Text 6 M: Uh, excuse me, Professor Muse? W: Oh, yes, Arnold, come in. M: You asked to see me after class? W: Yes, I did, Arnold. I just wanted to have a few words with you about your performance in class lately. Your last three test scores have been very disappointing. M: I know I have let you down. I will study much harder this semester. W: Well, I’m glad to hear that, Arnold, because if you don’t improve, you will not be able to get a B or above for the final exam. Text 7 W: We are going to put on a performance. M: Really? When? W: It’s only three days away----On May 4. We have been preparing for it for two months. M: Where are you going to put it on? At the Youth Square? W: No. At the People’s Theatre. M: What are you doing that for? W: We want to collect money for poor children in the mountainous areas. M: That sounds great. Good luck to you. W: Thanks a lot. Text 8 W: Hello, Mark. I’m the reporter from Sports Weekly. May I ask you some questions? M: Please go ahead. W: What makes you take part in such a long race? M: I have confidence in my strength. I manage to do some exercise every day. W: Do you mean that regular exercise contributes to your good health? M: Sure. Young people nowadays watch games on television and read about sports in the newspaper or on the Internet and state that they love sports. I can’t see any good of that. W: I am one of them. What shall I do? M: A human being is a kind of machine that wears out from lack of use. You can start with some easy movements, such as jogging. W: Shall I stick to one exercise? M: You can, but your general fitness level is likely to increase through different activities. W: Thank you. And I hope I can see you in the race next year. Text 9 M: Well, what’s on TV tonight? W: Ur, there is a rerun of Star Wars. M: Nah, I’ve seen it a billion times. I’d like to see something different. W: Okay, let’s see here. Oh, on channel 2 at 9:00, there’s a home improvement show about fixing anything around the house. We do have a few things that you could repair in the bathroom. M: Fixing things? Uh, I think I’m going to bed. I have to get up early tomorrow. W: Okay. Too bad, though. There’s a basketball game on right now, but I guess you can catch the score in tomorrow’s newspaper. M: Oh, okay. I’ll stay up and keep you company while I, I mean, We watch the game. W: I thought you’d change your mind. Text 10 Hello, everyone. I’d like to tell you something about the student clubs in our school. Let’s begin with our reading club. It was first started in 1968, and has 90 members now. Every Thursday afternoon, they gather together to exchange their ideas on books. And you may join them to share your views. If you are a music lover, come to our music club. This club has a total of 85 members who usually meet on Saturday. Sometimes they go to the concerts together and sometimes they give performances themselves. For those who enjoy outdoor sports, the bicycle club can be a good choice. Trips are usually organized on Wednesday and last at least two hours. Together with 50 cyclists, you can not only see the beautiful nature, but also make yourself stronger. Of course, there are also many other clubs in our school. For more information, please go to the school website.
『陆』 (2013保定二模)如图是表示人体部分生理活动示意图.其中A、B、C表示相关的器官,①②③④表示生理过程
(1)蛋白质在小肠内最终被消化为氨基酸,通过①过程小肠绒毛内的毛细血管吸收进入血液.
(2)A是肺,在A处进行气体交换是肺泡与血液之间的气体交换,肺泡里的氧气浓度高于血液,血液中的二氧化碳的浓度高于肺泡,因此肺泡里的氧气向血液里扩散,血液里的二氧化碳向肺泡扩散,这样,经过此过程之后,血液由含氧较少的静脉血变成了含氧丰富的动脉血.
(3)尿的形成包括:肾小球和肾小囊内壁的过滤和肾小管的重吸收作用.当血液流经肾小球的和肾小囊内壁时,除大分子的蛋白质和血细胞不能被过滤外,血浆中的一部分水、无机盐、葡萄糖和尿素等物质都可以过滤到肾小囊腔中形成原尿;当原尿流经肾小管时,原尿中大部分的水、全部的葡萄糖、部分无机盐被肾小管外包绕的毛细血管重新吸收回血液,而剩下的水、尿素和无机盐等就形成了尿液.据以上知识判断:正常的尿液中不会有红细胞和蛋白质,若出现了,可能是肾小球的过滤作用发生了病变,通透性增大,红细胞和蛋白质进入了原尿.因此,在尿液中发现含有较多红细胞和蛋白质.
(4)不同的内分泌腺分泌的激素不同,不同的激素的作用不同.甲状腺能分泌甲状腺激素,若甲状腺幼年分泌不足,会导致呆小症,身材矮小,智力低下;成年甲状腺分泌过多导致甲亢,因此,呆小症是由于婴幼儿时甲状腺激素分泌不足导致的.
故答案为:(1)氨基酸;
(2)动脉;
(3)肾小球;
(4)甲状腺激素.
