Even when I was very young, I always loved plants. When I walked to school, I would look at the different plants along the way. I would make up names for them. I would draw pictures of them. When my teacher asked us to draw a picture of anything we liked, I always drew pictures of plants.

Now I teach about plants at a college. I keep learning more about plants and the animals that depend on them. I learn from the Internet now, and sometimes go to the park and study the plants in my neighbourhood.

【B】

In order to show that showering isn't a big deal, an American hasn't taken a shower for 12 years. Instead, he sprays (喷洒) himself with something special that is said to have kept him clean over the years.

Dave Whitlock, a chemical engineer, thinks no fact can show that bathing is a healthy practice. “I haven't taken a shower for 12 years,” he says. “In fact, the chemical (化学物) in our soap have killed all the friendly bacteria (细菌) that live on our skin when we use it.”

For a long time, many people haven't realized skin bacteria are important and helpful to the body. Whitlock isn't a biologist (生物学家), but he has tried his best to invent (创造) a kind of spray called “Mother Dirt” with friendly bacteria. Whitlock says the bacteria in the spray can take in (吸收) something dirty on our skin and produce a kind of chemical which is good for our body.

Now the spray is being produced in a company which Whitlock has helped to set up. The spray has no smell and feels just like water. It can be sprayed all over the skin twice a day to avoid showering. And for those who really enjoy showering, the company is planning to develop a kind of special shower gel (沐浴露) with friendly bacteria.

( )6.Why hasn't Whitlock taken a shower for 12 years?

A.Because he hates showering. B.Because he wants to prove (证明) his idea.

C.Because there aren't any friendly bacteria on his skin. D.Because he is too busy with his work. ( )7.Which is TRUE about the spray invented by Whitlock?

A.It can help to keep the skin clean and healthy. B.It can help the skin produce more friendly bacteria.

C.It smells better than shower gel we use. D.There are not any chemicals in it.

( )8.What can we know about Dave Whitlock?

A.He is an American biologist. B.He thinks showering is important.

C.He always uses some soap to wash himself.D.He's trying to make people learn a lot about showering. ( )9.What can we know from the passage?

A.Whitlock says that we should take showers often.

B.Almost everyone knows the importance of skin bacteria.

C.Using soap often is harmful to our skin's health.

D.The spray Whitlock invented is becoming more and more popular.

( )10.What's the best title for the passage?

A.The Use of Friendly Bacteria. B.A Strange American Biologist.

C.No Showering For 12 Years. D.The Importance of Cleaning the Skin.

六、任务型阅读,每空一词。(共10小题,每空1分,共10分)

Many large cities are not so beautiful. There is a lot of rubbish in the streets. However, some of the rubbish can be useful. If people want to solve the problem, they should do it right now. They must take action to make use of rubbish. In this way, some good things will not be thrown away as waste.

When a car gets too old, it may not run any more. But if the metal (金属) that the car was made of is still good, we can use it to make something else. When a bottle is empty, it will be thrown away. But the bottle glass can be made into sand and used to build streets. Rubbish from food can be changed into fertilizer (肥料). It is cheap and safe. Other rubbish can also be used to make buildings. It can be mixed with concrete (混凝土) to form special bricks. Now, more and more machines are designed for that.

Some day, people will watch films in a beautiful cinema which is built out of rubbish. Besides, in the future, buildings, roads, and cities may be made from rubbish. But so far, it is only a dream to build beautiful cities out of rubbish.

A dream of (1) the rubbish

(2) for making use of rubbish ◆The street is (3) of rubbish.

◆Some of the rubbish can be (4) again.

(5) of making use of rubbish ◆The metal of old (6) can be used to make something else.

◆The bottle glass can be made into (7) and used to build streets.

◆Rubbish from (8) can be turned into fertilizer.

◆Other rubbish can be used to (9) special bricks to make buildings.

The dream of using rubbish to build beautiful cities hasn’t come (10) .

七、首字母填空。(共10小题,每空1分,共10分)

“Go Green” can mean many different things to different people. For some people, it means something very s (1). You may think about the environment. For others, it means that you should live in a way that is not h (2) to the health of people or animals. It’s not n (3) for you to change your lifestyle completely (完全地), but small changes can help make the environment cleaner and safer.

How can you “Go Green”? The following s (4) may help.

●You should use products (产品) that are good for the environment instead of

using those that might p (5) the environment.

●You should use washing and cleaning products with n (6) materials and

colours.

●You had better r (7) the products you have used.

●You shouldn’t buy things that you don’t r (8) need. You need to buy less

because you must s (9) the energy for the next generation (代).

北京回民学校数学分式填空选择单元测试题(Word版 含解析)

北京回民学校数学分式填空选择单元测试题(Word 版 含解析) 一、八年级数学分式填空题(难) 1.如果关于x 的分式方程1a x +-3=11 x x -+有负分数解,且关于x 的不等式组2()43412 a x x x x -≥--???+<+??的解集为x <-2,那么符合条件的所有整数a 的积是_________. 【答案】9 【解析】 ()243412a x x x x ?-≥--??+<+?? ①②, 由①得:x≤2a+4, 由②得:x<-2, 由不等式组的解集为x<-2,得到2a+4≥-2,即a≥-3, 分式方程去分母得:a-3x-3=1-x , x=42 a -, 由分式方程 1a x +-3=11x x -+有负分数解,则有a-4<0,所以a<4, 所以-3≤a<4, 把a=-3代入整式方程得:-3x-6=1-x ,即x=- 72 ,符合题意; 把a=-2代入整式方程得:-3x-5=1-x ,即x=-3,不合题意; 把a=-1代入整式方程得:-3x-4=1-x ,即x=- 52 ,符合题意; 把a=0代入整式方程得:-3x-3=1-x ,即x=-2,不合题意; 把a=1代入整式方程得:-3x-2=1-x ,即x=-32 ,符合题意; 把a=2代入整式方程得:-3x-1=1-x ,即x=-1,不合题意; 把a=3代入整式方程得:-3x=1-x ,即x=-12 ,符合题意, ∴符合条件的整数a 取值为-3,-1,1,3,之积为9, 故选D 【点睛】本题考查了解一元一次不等式组,以及解分式方程,熟练掌握运算法则是解本题的关键.

2.若关于x 的分式方程 321 x m x -=-的解是正数,则m 的取值范围为_______. 【答案】m >2且m ≠3 【解析】 解关于x 的方程 321 x m x -=-得:2x m =-, ∵原方程的解是正数, ∴20210m m ->??--≠? ,解得:2m >且3m ≠. 故答案为:2m >且3m ≠. 点睛:关于x 的方程321 x m x -=-的解是正数,则字母“m ”的取值需同时满足两个条件:(1)2x m =-不能是增根,即210m --≠;(2)20x m =->. 3.如果实数x 、y 满足方程组30233 x y x y +=?? +=?,求代数式(xy x y ++2)÷1x y +. 【答案】1 【解析】 解:原式=222()xy x y x y x y ++?++=xy +2x +2y ,方程组:30233x y x y +=??+=?,解得:31x y =??=-? ,当x =3,y =﹣1时,原式=﹣3+6﹣2=1.故答案为1. 点睛:此题考查了分式的化简求值,熟练掌握运算法则是解本题的关键. 4.若方程 256651130 x x k x x x x ---=---+的解不大于13,则k 的取值范围是__________. 【答案】15k ≤且k ≠±1. 【解析】 【分析】 通过去分母去括号,移项,合并同类项,求出112 k x += ,结合条件,列出关于k 的不等式组,即可求解. 【详解】 256651130 x x k x x x x ---=---+ 方程两边同乘以(x-6)(x-5),得:22(5)(6)x x k ---=, 去括号,移项,合并同类项,得:211x k =+, 解得:112 k x +=,

近三年高考理综(全国卷2)化学试题分析与启示

近三年高考理综(全国卷2)化学试题分析与启示2014、2015、2016年考点对比分析

二、试题考查特点分析 从近三年高考理综化学卷的对比分析中可以看出,试题遵循新课标高考《考试大纲》和《考试说明》的要求,在继承的基础上有创新,在创新中立足基础,注重能力。在注重对化学学科中的基础知识、基本能力和重要方法考查的同时,突出了对信息整合能力、问题解决能力、计算能力的考查。主要表现在: 1、注重对化学基础知识、主干知识的考查,保持试题稳定 近三年高考全国理综Ⅱ卷化学试题突出了对中学化学核心内容和主干知识的考查,涉及的知识均是中学化学基础知识,尽可能地突出所考查范围的主干知识,题目考查的知识点明确、具体。试题虽然在解答思路和思维层次上要求较高,但知识均源于课本,试题的落脚点比较基础,即高起点低落点。纵观近三年的试题变化,物质的分离、提纯;同分异构体;元素构、位、性关系;电化学;化学反应速率与化学平衡;有机物的结构与性质;化学反应方程式(包括离子方程式、电极反应式);等考点几乎是每年必考的内容,基本涵盖了高中化学的核心内容和主干知识。试题遵循《考试大纲》和《考试说明》的内容和能力要求,体现了“源于教材,高于教材,理在书内,题在书外”的命题原则。 2、突出对能力的考查,注重知识迁移知识迁移 高考作为选拔性考试主要体现在能力考查上,为了选拔具有学习潜能和创新精神的考生,考试以能力测试为主导,在测试考生进一步学习所必需的知识、技能和方法的基础上,全面检测考生的化学学科素养。近三年高考试题在能力测试方面突出下列特色: (1)注重计算能力的考查 近三年高考全国理综卷化学试题均对考生计算能力进行了考查,且加大了考查力度。命题时没有刻意设计一些“玩味”计算,体现基本化学计算思想和化学计算的实用价值。 (2)注重考查考生对图表信息的分析能力和数据处理能力 中学化学中很多材料和事实都可以通过图表信息呈现,如化学反应速率、化学平衡、电解质溶液的导电性、溶解度、酸碱中和滴定中的pH等。图象和表格中含有大量的信息,信息中有的是隐性的,考生必须对观察结果进行分析加工,才能发现其中所反映出来的规律,提取所需要的信息。例2014年26、28题;2015年26、27题都是如此。 (3)注重阅读能力的考查 《考试大纲》和《考试说明》中对考生提取和整合信息的能力提出了要求。近三年高考试题对此都有加强,如果考生不能根据试题提供信息对题中条件进行有效的分析和整合,发散联想基本知识点,对该问就不能做到准确解答。

化学考试不及格检讨书范文3篇

化学考试不及格检讨书范文3篇化学考试没考好,化学老师会生气的,罚写检讨算是较轻的惩罚了。那么以下是小编为大家整理的化学考试不及格检讨书范文,欢迎大家阅读! 化学考试不及格检讨书范文一:尊敬的化学老师: 我感觉我这次化学考试的分数是很低的,这远远没有达到我心目当中的一份理想成绩。然而,考试成绩实实在在地公布出来了,我考得不好是板上钉钉,铁一般的事实,不容我丝毫推脱。考试成绩不好,只能够说明我对这一科目的知识掌握得不够深透与全面。 成绩考差以后,我倍感苦恼,经过这一段时间的深刻反省。我总结出了造成这次考试失利的原因: 1、平时不注意化学知识的专研,也可以说是我对于化学这门科目的学习不够重视。 2、日常没有抽出足够的时间来完成化学作业,很多时候是没有时间留给化学作业的。 3、有时候自己也上课开小差,对于一些知识点没有细致、准确地掌握。 现在我考试已然失利,我痛苦难当,我也很懊悔。可是我也知道再多的言辞都显得苍白无力,我只有勇敢地面对目前形势,

集中精力、时间、条件用于提高自身学习成绩,在下一次大考当中取得优秀的化学成绩才是给老师最好的交待。 检讨人:xxx 20xx年xx月xx日 化学考试不及格检讨书范文二:尊敬的老师: 您好! 在这次的化学考试中,我不及格,作为一名理科生,这本来是不应该的行为,但是在数理化这三门重点科目上,我的化学又是最弱的了。其他科目我都可以很好的学习和理解,但是对于化学来说,总是像隔着一层纱一样,上课看起来听懂了,做题目的时候似乎也知道做了,但是一到考试的时候,就现行了,根本就不会做了。这次期末的考试,更是出现了退步,不及格了。我也感到很焦虑,毕竟下学期就是高三了,化学要是没学好,也影响我高考的成绩。 还是在初中的时候我的化学就不是太好,勉强可以70多分,不上不下的样子,进入高中以来,要记的东西,背的东西更多了,虽然勉强,但分数总是提不上去,在面临分班的时候,虽然有点犹豫,但还是选择了理科,毕竟我的历史和政治更是学不好,况且我的物理和数学都是挺好的,所以选择了理科。 到了高二的阶段,化学的知识变得更加复杂而多了,像电解,
