四川省成都市龙泉中学、温江中学等五校2016-2017学年高二上学期期中联考物理试题一、单项选择题(1-6题,每小题只有一个选项,每小题3分,共18分)1.现在有一档科学探索的电视直播节目,很受欢迎。
在某期节目里,一位少女站在绝缘平台上,当她用手触摸一个金属球时,会看到她的头发慢慢竖起,如图所示,像是孔雀开屏。
下列说法正确的是()A.头发竖起是因为她身上带了静电B.她只有带正电荷时,头发才会竖起C.她的头发慢慢竖起是因为电荷慢慢传到她的头发上D.与电无关,这是她的特异功能2.如图是静电喷涂原理的示意图.喷枪喷嘴与被涂工件之间有强电场,喷嘴喷出的带电涂料微粒在强电场的作用下会向工件高速运动,最后被吸附到工件表面.则可知()3.两根由同种材料制成的均匀电阻丝A、B并联在电路中,A的长度为L,直径为d;B的长度为2L,直径为2d,那么通电后在相同的时间内产生的热量之比为()A.Q A:Q B=2:1 B.Q A:Q B=4:1 C.Q A:Q B=1:1 D.Q A:Q B=1:24.两个较大的平行板A、B相距为d,分别接在电压为U的电源正负极上,开关S闭合时质量为m,带电量为﹣q的油滴恰好静止在两板之间,如图所示,在保持其他条件不变的情况下,将两板非常缓慢地水平错开一些,以下说法正确的是()A.油滴将向上运动,电流计中的电流从b流向aB.油滴将下运动,电流计中的电流从a流向bC.油滴静止不动,电流计中的电流从a流向bD.油滴静止不动,电流计中无电流流过5、如图所示,甲、乙两个电路都是由一个灵敏电流表G和一个变阻器R组成的,下列说法正确的是()A.甲表是安培表,R增大时量程增大B.甲表是安培表,R增大时量程减小C.乙表是伏特表,R减少时量程增大D.乙表是伏特表,R增大时量程减小6.如图所示,电源电动势为E=30V,内阻为r=1Ω,电灯上标有“6V,12W”字样,直流电动机线圈电阻R=2Ω.若电灯恰能正常发光,则:A.通过电动机的电流为0.5AB.电动机两端电压为20VC.电动机的输出功率36WD.电路在1分钟产生的热量为60J。
2017~2018学年度高一年级第二学期期初教学质量调研语文试题一、语言文字运用1. 在下面一段话空缺处依次填入词语,最恰当的一组是()黄公望的风格竟是因为他不形成风格,仿佛在绘画之外,对山水、对人世,他有那么多的爱与追求,有那么多的宽容大度,因而笔墨的自在、布局的,在他的杰作《富春山居图》中都到了令人的地步。
A. 刻意灵活叹为观止B. 故意空灵叹为观止C. 刻意空灵高山仰止D. 故意灵活高山仰止【答案】A【解析】试题分析:辨析近义词要从所给词语的词义、词性、轻重程度、适用对象、范围大小、感情色彩等角度考虑,一定要切合语境。
此题用排除法。
刻意:用尽心思;故意:存心,有意识地。
很显然此处用“刻意”。
排除BD两项。
灵活:不呆板,不拘泥于固有模式;空灵:灵活而不可捉摸,往往指人或思想。
这里应用“灵活”。
故选A。
再者叹为观止:指赞美看到的事物好到极点。
高山仰止:指对高尚的品德的仰慕。
根据语境,应选“叹为观止”。
2. 下列各句中,没有语病的一句是( )A. 网络反腐是新媒体时代的一大热点,特别是一批大案要案的查处,大大提振了民间反腐倡廉的信心,激发了民众网络反腐的热情。
B. 如果治疗及时,脑积水治疗效果会很好,一旦延误治疗,错失了最佳治疗时机,不仅可能危及生命,甚至会导致孩子脑瘫。
C. 近几年,随着“全民摄影时代”、全媒体时代以及高清视频截图的出现,以生产静态照片为职业的摄影记者的生存空间受到多方面挤压。
D. 为群众排忧解难,切忌不能停留在口头上,要有实际行动,让老百姓看得见、感受得到,从小事做起,比如了解群众需求,尽量方便群众。
【答案】A【解析】试题分析:B项,语序不当,应将“不仅可能危及生命,甚至会导致孩子脑瘫”改为“不仅会导致孩子脑瘫,甚至可能危及生命”。
C项,成分残缺,缺少和“随着”呼应的中心词,应在“全媒体时代”后面加上“的来临”。
D项,“切忌不能停留在口头上”不合逻辑,应将“切忌”删除。
点睛:本题考查辨析病句的能力,辨析病句首先应熟知病句的类型,最常用的判别方法是划分句子结构成分,先看主谓宾,再看定状补,判断句子是否存在成分残缺赘余、搭配不当、结构混乱、语序不当等问题。
成都市“五校联考”2017-2018学年第三学期期中试题生物(全卷满分:100分完成时间:90分钟)1.下列关于现代生物进化理论的叙述中,不正确的是( )A.现代生物进化理论是在研究种群中基因频率变化的基础上发展起来的B.进化改变的是群体而不是个体C.物种形成包括突变和基因重组、自然选择、隔离三个基本环节D.突变可以改变生物进化的方向2.如图所示为种群与物种的关系图解,关于它们的叙述不正确的是 ( )A.从图中可以看出,一个物种可以有很多种群,这些种群间只是因为地理隔离,阻碍了基因交流B.若物种2是由物种1形成的,则物种1一定发生了基因频率的改变C.交配后能产生后代的一定是同一物种,由物种1形成物种2的必要条件是地理隔离,D.若种群1与种群2的基因频率都发生了改变,则这两个种群都在进化3.下列关于生物进化和新物种形成的叙述,不正确的是( )A.用皮康霜治疗皮肤病,使用一段时间后,药效下降,这是由于引起皮肤病的病原体接触药物后,产生了对皮康霜药物有效成分的抗药性变异B. 19世纪的英国工业革命,使灰色桦尺蛾变成——黑色桦尺蛾,黑色桦尺蛾是进化的结果,但不是新物种C. 华南虎和东北虎的形成,只有地理隔离,没有生殖隔离,还是同一物种D. 海南热带野生动植物园的公狮和母虎交配,产下不育的“狮虎兽”,说明狮子和老虎存在生殖隔离4.已知苯丙酮尿症是位于常染色体上的隐性遗传病。
据调查,该病的发病率为1/10000。
请问,在人群中苯丙酮尿症致病基因的基因频率和携带此隐性基因的杂合基因型频率各是多少?()A. 1%, 1.98%B.1%, 99%C.1% , 1.89%D.1%, 98% 5.下表是某物种迁入新环境后,某对等位基因的基因频率变化情况,由这些数据不能得出的结论是()A.由于种群基因频率改变,该生物发生了进化B.a基因控制的性状可能更适应新环境C.1970年,该种群中Aa的基因型频率为18%D.基因频率的改变是通过环境对生物个体的选择实现的6.油菜物种甲(2n=20)与乙(2n=16)通过人工授粉杂交,获得的幼胚经离体培养形成幼苗丙,用秋水仙素处理丙的顶芽形成幼苗丁,待丁开花后自交获得后代戊若干。

Shared bikes bring people great convenience as they provide an effective solution to the “last mile” problem. Hence, shared bikes should be left in public for next users. It is morally wrong that we take possession of one for our own selfish interest. I advocate raising our awareness of using shared bikes reasonably so that everyone can benefit from this service. Li Hua (91 words) 第二节概要写作 Possible version: A new research shows that student strain often coexists with teacher exhaustion. (要点1) Students, who find their requirements unsatisfied as a result of teachers’ low-level management over class, may feel overwhelmingly stressed. (要点2) Conversely, teachers, who encounter great teaching challenge from students, tend to be burned out. (要点3) Therefore, more sufficient resources and support to teachers should be guaranteed, or students are likely to be ruined. (要点4) (63 words)
听力原文 Text 1 W: Excuse me, is this novel available? My friend told me she bought it here. M: Sorry, I sold the last copy just a moment ago. Text 2 W: Aren’t you cold? Why aren’t you wearing a jacket? M: I overslept this morning, so I ran out of the house without listening to the forecast. Text3 W: Sir, did you see the “No Parking” sign ? M: I won’t be here long. My wife will finish shopping in five minutes. W: Sorry, sir. Not even for one minute! You’ll get fined if you don’t go! Text 4 2
M: The sports meeting was exciting. A boy named Billy broke the record which he set one year ago himself. W: Ben and I witnessed the whole event. It was amazing! Text 5 W: I like these cloth bags. How much are they? M: They are 30 yuan each or 55 yuan a pair.
Text 6. W: Didn’t we invite Ruby to the party tonight? M: I don’t think she’ll make it. W: Why? Is she busy with anything today? M: She’s an important examination to take part in tomorrow. I’m afraid she’ll prepare for it. By the way, have we invited Tom? W: Yes. And he said he would come. M: What about Lily? W: She has travelling in Hangzhou now. She will not return until next Sunday. Text 7 W:Did you hear that a new gym opened on one of the streets nearby? M:That’s great news! Do you know if the new gym offers Latin Dance classes? W:I’m not sure. I’m planning to go there on Thursday evening to look around. Do you want to join me? M:Let me check my schedule for this week. I’m too busy on Thursday, so can we go on Sunday afternoon instead? W:Sure. We can see what the new gym has to offer, and get some exercise, too. It’s fun to work out in a gym with other people. We might even meet new people with similar hobbies! M:Hold on, let’s see what the gym looks like first before we start planning anything else. Let’s meet at the White Rainbow Café for lunch before we go. It might be the last good meal we eat! W:Good plan!
Text 8. W: Can I help you? M: Yes. My son bought this mobile phone here for my wife’s birthday. But it doesn’t work. So I’d like to change it for another one. W: I see. Let me have a look. Well, we’ll be happy to change it for you. But I am afraid we don’t have another red one. M: Oh? What will I do then? W: Would you like to choose a different color? We do have this mobile phone in black and orange. M: My wife doesn’t like either of those colors. W: If you want, we can order another mobile phone just like this one. There wouldn’t be any extra charge for it. M: That sounds fine. Would you please go ahead and do that? W: We’d be very happy to but it’ll take at least a week. Maybe ten days.

Text 9 W: Jim, did you hear that they’re going to make a new film in our neighborhood? The building manager sent out a letter saying our street will be closed for a week. M: What? That's terrible! W: Maybe we'll get to see some movie stars!I heard some top actors are in the film. M: I think I'll write a letter to the mayor. W: Wait... you aren't happy about this? M: Not at all! I remember the last action film that was made nearby for half a month. It was such a headache for all the residents—streets closed, people all over the place. My company had invited some important people to a meeting. They were from out of town, but all the hotels were booked. W: Well, it'll be shorter this time… M: I doubt it. When they say they're filming for a week, it takes them at least ten days to get out of here. They have to set up, film the movie, and then take everything down again. It's a big deal. W: I’m sure that's why the mayor wanted the movie to be filmed here — because it’ll make a lot of money for the city. Think of how much the city will make from all the food and hotel rooms the movie people will pay for… not to mention all the local people they’ll hire to do the extra work.
