2015-2016学年上海市沪教版四年级下册期终练习数学试卷(解析版)

【点睛】本题考查小数的近似数,注意小数部分末尾的“0”是不能去掉的。
16.两条直线如果不平行,那么一定是垂直的。( )
【答案】×
【解析】
【分析】
【详解】同一平面内,两条直线如果不平行,那么一定是相交的,所以判断错误。
17.过直线外一点画已知直线的平行线只能画一条,如果要画和已知直线相距1cm的平行线就可以画出2条。 ( )
=100×25
=2500
四、列综合式计算8%
4.列综合式计算
甲数是10.4,乙数比甲数少0.7,两个数的和是多少?
【答案】20.1
【解析】
【分析】甲数减去0.7等于乙数,再加上甲数即可解答。
【详解】10.4-0.7+10.4
=9.7+10.4
=20.1
5.列综合式计算
100除25与4的积,所得的商减去0.2,差是多少?
【答案】图见详解;2
【解析】
【分析】过一点作直线的垂线:把三角板的一直角边靠紧直线,沿这条直线滑动三角板,当另一直角边经过该点时,沿这条直角边画的直线就是过该点作的直线的垂线;过直线外一点作直线的平行线:把三角板的一边靠紧直线,另一边靠紧一直尺,沿直尺滑动三角板,当与直线重合的一边经过已知点时,沿这边画直线就是过该点作的直线的平行线。再测量点A到BC的垂线段的长度即可解答。
【解析】
【分析】小数大小的比较:先看它们的整数部分,整数部分大的那个数就大;如果整数部分相同,十分位上的数大的那个数就大;如果十分位上相同,百分位上的数大的那个数就大,以此类推。小数的性质:小数的末尾添上“0”或去掉“0”,小数的大小不变。
【详解】0.031<0.301<0.309<0.310
0.310=0.31

由于他医术高超,被人们称为“神医”。
然而,有一件事却使他深感不安。
那时候没有麻醉药,动手术的病人常常痛得连声惨叫。
有一次,一个小孩胳臂上长了毒疮,需要割去(fǔlàn)( )的肉。
华佗给他动手术,那小孩痛得乱蹦乱跳,发出(sīxīn lièf èi)( )般的惨叫。
华佗只得叫来几个大汉死死地把他按住,又用绳子捆起来,才勉强把手术做完。
看着痛得死去活来的孩子,华佗心想:有什么办法能使动手术的病人不感到疼痛呢?事也凑巧,有一天,几个人抬着一个折了腿的汉子来找华佗医治。
华佗给他动手术,那汉子不仅没有挣扎、(shēn yín)( ),反而软绵绵的,(rèn rénbǎi bù)( )。

二、阅读理解。
(29%)细菌发电前景广阔 14%①生物学家预言,21世纪将是细菌发电造福人类的时代。
②说起细菌发电,可以追溯到1910年。
英国植物学家利用铂作为电极放入大肠杆菌的培养液中,成功地制造出了世界上第一个细菌电池。
1984年,美国科学家设计出太空飞船使用的细菌电池,其电极的活性物质是宇航员的尿液和活细菌。
到了80年代末,细菌发电有了重大突破,英国科学家让细菌在电池组里分解分子,释放电子向阳极运动,从而产生电能。
操作时还在糖液中添加某些芳香化合物作为稀释液,来提高生物系统输送电子的能力。
与此同时,还要往电池里不断地充入空气,用以搅拌细菌培养液和氧化物质的混合物。
据计算,利用这种细菌电池发电,其效率可达40%,远远高于现在使用的电池的效率,且能持续数月之久。
即使这样,还有10%的潜力可挖掘。
③利用细菌发电原理,可以建立较大规模的细菌发电站。
计算表明,一个功率为1000千瓦的细菌发电站,仅.需要10立方米体积的细菌培养液,每小时消耗200千克糖即可维持其运转发电。
这是一种不会污染环境的“绿色”电站,而且技术发展后,完全可以用诸如锯末、秸秆、落叶等废有机物的水解物来代替糖液。
因此,细菌发电的前景十分诱人。
④现在,各个发达国家各显神通,在细菌发电研究方面取得了新的进展。
美国设计出一种综合细菌电池,里面的单细胞藻类可以利用太阳光将二氧化碳和水转化为糖,然后再让细菌利用这些糖来发电。
日本科学家同时将两种细菌放入电池的特种糖液中,让其中的一种细菌吞食糖浆产生醋酸和有机酸,而让另一种细菌将这些酸类转化成氢气,由氢气进入磷酸燃料电池发电。
⑤人们还惊奇地发现,细菌还具有捕捉太阳能并把它直接转化成电能的特异功能。
最近美国科学家在死海和大盐湖里找到一种嗜盐杆菌,它们含有一种紫色素,在把所接受的大约10%的阳光转化成化学物质时,即可产生电荷。
科学家们利用它们制造出一个小型实验性太阳能细菌电池,结果证明是可以用嗜盐性细菌来发电的,用盐代替糖,其成本就大大降低了。
由此可见,让细菌为人类供电已经不再遥远,不久的将来即可成为现实。
1、本文的说明对象是()2%A.细菌发电原理B.细菌发电前景C.细菌发电D.细菌发电研究2、本文第②段至第④段用的说明顺序是()2%A.时间顺序B.从整体到局部的顺序C.事物发展的顺序3、“生物学家预言,21世纪将是细菌发电造福人类的时代”,下列对“细菌发电”优势的说法不正确的选项是()2%A.效率高B.绿色环保(即不污染环境)C.让细菌利用糖来发电D.发电成本低廉4、第②段介绍研究利用细菌电池发电时,为提高发电效率,操作时采取了哪些措施()2%A.让细菌在电池组里分解分子,释放电子向阳极运动,从而产生电能。
B.糖液中添加某种芳香化合物作为稀释液。
C.往电池里不断地充入空气。
D.糖液中添加某种芳香化合物作为稀释液;往电池里不断地充入空气。
5、说说第②段划横线句主要运用了_________的说明方法,把_________________和___________________ 加以比较,突出强调了_____________________________________________________________________。
4%6、第③段中的“仅”字能否去掉?说说理由。
2%____________________________________________________________________________________________(二)父亲留下书香 15%我们这个寻常百姓家,收入不多,住房又小,挤挤巴巴的,连一个书橱也放不下。
虽说不是“书香门第”,却有缕缕书香mí漫,这可以从家里的桌上、凳上、床头枕边到处堆放着的书本看出,更能从我和妻子、儿子饭后xiá余常常是各人手执一卷昭然可见……说起我家的书香,还是我父亲传留下来的哩。
父亲别无嗜(shì)好,就喜欢看书。
《三国演义》、《水浒传》、《红楼梦》以及《钢铁是怎样炼成的》等古今中外名著,曾使他每每陶醉于其中。
父亲给我们讲起这些故事来更是tāo tāo 不绝。
可是,后来父亲的手中却换成了一本本“苦书”——这,说来话长了。
我母亲生我二弟后一病不起,常年躺在床上,生活不能自理,父亲独自挑起了持家的重担。
起先请医生为母亲治病,后来家境日趋贫困,再也没钱请医生了,我们为此忧心忡忡....(chōng)。
这时我发现父亲床头的《三国演义》、《水浒传》等书不见了,取而dài 之的是一本本中医和中草药书,——这些就是“苦书”吧。
劳累之余,父亲就埋头研读这些书,可谓是“苦”不释手。
父亲还钻研一本《中国针炙大纲》,边看边实践:替我母亲望诊搭脉,开方煎药,又作针炙治疗。
后来连我们兄弟姐妹也知道了这个常识,在足三里穴位针炙能起到有病治病,无病防病的效果。
奇迹终于降临,卧床数年的母亲竟然..下床了!母亲感慨地叮咛我们要秉(bǐng)承父亲的精神。
为了给母亲作针炙治疗,父亲常常在晚上先在自己身上的穴位进行试针,感觉针刺麻醉的程度和针尖刺透的深度,然后再替我母亲针炙治疗……母亲的病治好了,她享受到古稀之年,而操劳一生、挚爱妻子儿女的父亲却在65岁离开了我们!父亲留给我们的很多很多,其中就有不绝如缕的书香。
1、在文中拼音后的横线处写上汉字。
4%书香mí漫饭后xiá余取而dài 之 tāo tāo 不绝2、第二自然段中“可是后来父亲的手中却换成了本本‘苦书’”,“苦书”指的是()3%A.《三国演义》、《水浒传》、《红楼梦》以及《钢铁是怎样炼成的》等古今中外名著。
B.父亲在母亲生病后读的中医和中草药书。
C. 《中国针炙大纲》。
3、“卧床数年的母亲竟然..下床了。
”中“竟然”的意思表示()3%A.母亲常年躺在床上,现在竟下床了,这简直是个奇迹。
B.父亲钻研“苦书”,使卧床数年的母亲能够重新站了起来,这简直不可思议啊!C.父亲钻研“苦书”,使卧床数年的母亲能够重新站了起来。
D.父亲常常在晚上先在自己身上的穴位进行试针,感觉针刺麻醉的程度和针尖刺透的深度,然后再替母亲针炙治疗……4、文章最后一段,作者充满深情,“父亲留给我们的很多很多”,请你联系全文想一想,“很多很多”指父亲留下的哪些东西?(至少写两条)3%__________________________________________5、关于读书,前人留下很多体会,你是否还记得:三国时代学者董遇认为读书要熟读,他说:“书读百遍,。
”;宋代大学者朱熹读书时很有感慨,认为书好比清澈的池塘,他在《观书有感》中写道,“问渠那得清如许,。
”2%三、作文30+5%提示:谁说我们整天都是快乐的,其实,我们也有烦恼。
请在脑海中为自己画一张漫画,并根据这张漫画展开想象,自己命题写一篇作文。
要求:①题目自拟。
②通过一件事写出自己心中的烦恼。
