1939年用英语怎么说？必定采纳，最高分，

C

子鼠、丑牛、寅虎、卯兔、辰龙、巳蛇、午马、未羊、申猴、酉鸡、戌狗、亥猪
比如：今年是龙年,2012与1939之间就是73年的差距,生肖一轮12年,12*6=72, 这样就可以得出1939年出生的生肖了
希望对你有帮助.

（1）A装置是指取二氧化碳气体的装置，是碳酸钙和盐酸发生反应生成氯化钙、水和二氧化碳；反应的离子方程式为：CaCO ₃ +2H ⁺ ═Ca ²⁺ +CO ₂ ↑+H ₂ O；C装置稀硫酸是尾气处理装置吸收过量的氨气，防止污染环境，
故答案为：CaCO ₃ +2H ⁺ ═Ca ²⁺ +CO ₂ ↑+H ₂ O；吸收从B装置中的试管内逸出的氨气，减少对环境的污染；
（2）B装置中的试管内是溶有氨和氯化钠的饱和溶液，通入二氧化碳气体会发生反应生成碳酸氢钠和氯化铵，依据图标分析可知温度越低，碳酸氢钠的溶解度越小，所以温度越低越有利于碳酸氢钠的晶体析出，
故答案为：温度越低，碳酸氢钠的溶解度越小，便于析出；
（3）二氧化碳气体中含有氯化氢气体，通入后和氨气反应不能生成碳酸氢钠，所以的不到碳酸氢钠晶体，所以需要加一个洗气装置用饱和碳酸氢钠溶液除去二氧化碳中的氯化氢气体，
故答案为：A与B；饱和NaHCO ₃ 溶液；除去CO ₂ 中混合的HCl气体．

（1）电视机的遥控器可以发出红外线，不同按钮发出红外线的频率是不同的．
我们看到的电视节目信息是通过电磁波传递过来的，手机所能传递信息也是通过电磁波进行传递的，故当正在收看节目的电视机旁边的手机响了，电视机会发出“咔咔”声，这一现象验证了电磁波的存在，同时由于电磁波能在真空中传播，即使把手机放在真空玻璃罩中，电视机仍会受到干扰．
（2）彩色电视机可以发出光的三基色，即红、绿、蓝．
在工作的过程中，屏幕上有静电，可以吸引空气中的灰尘．
（3）电视机工作的过程中，电能转化为声能、光能、内能．
1KW•h=3.6×10 ⁶ J．
根据电能表的铭牌可知，消耗1KW•h的电能，表盘转3000r．
所以当表盘转15r时，消耗的电能=
15
3000 KW•h=0.005KW•h，合1.8×10 ⁴ J．
2min=120s
根据电功率的公式可得：P=
W
t =
1.8× 10 4 J
120s =150W
故答案为：（1）红外线；频率；电磁波；会．（2）绿；静电．（3）光；内；150．

解题思路：考查光合作用的探究历程中鲁宾和卡门的实验．鲁宾和卡门利用¹⁸O分别标记H₂O和CO₂使它们分别成为H₂¹⁸O和C¹⁸O₂．然后进行两组实验：
第一组向植物提供H₂O和C¹⁸O₂；第二组向同种植物提供H₂¹⁸O和CO₂．在其他条件都相同的情况下，他们分析了两组实验释放的氧气．结果表明，第一组释放的氧气全部是O₂；第二组释放的氧气全部是¹⁸O₂．这一实验有力地证明光合作用释放的氧气来自水．

A、萨克斯实验：首先把绿叶先在暗处放置几小时，目的是消耗掉叶片中的营养物质．然后，让叶片一半曝光，另一半遮光．过一段时间后，用碘蒸气处理这片叶，发现曝光的一半呈深蓝色，遮光的一半则没有颜色变化．这一实验成功地证明光合作用的产物除氧气外还有淀粉，A错误；
B、鲁宾和卡门的实验证明光合作用释放的氧气来自水而不是根的吸水方式，B错误；
C、鲁宾和卡门利用¹⁸O分别标记H₂O和CO₂使它们分别成为H₂¹⁸O和C¹⁸O₂．然后进行两组实验：
第一组向植物提供H₂O和C¹⁸O₂；第二组向同种植物提供H₂¹⁸O和CO₂．在其他条件都相同的情况下，他们分析了两组实验释放的氧气．结果表明，第一组释放的氧气全部是O₂；第二组释放的氧气全部是¹⁸O₂．这一实验有力地证明光合作用释放的氧气来自水，C正确；
D、卡尔文用¹⁴C标记空气中的¹⁴CO₂，供小球藻进行光合作用，然后追踪检测其放射性，最终探明了CO₂中碳在光合作用中转化成有机物中碳的途径，D错误；
故选：C．

点评：
本题考点： 光合作用的发现史．

考点点评： 本题难度中等，属于考纲理解层次．解答本题的关键是理解鲁宾和卡门的实验过程．

仅供参考：Year 1939 saw the outbreak of the second world war.或者 The Second World War broke out in 11939.

The world war two took place in 1939.
My grand father drinks a great deal wine.
By the age of 65, he is still working.
The policeman succeeded in solving this case finally.
He enjoys various kinds of sports and amoung them he likes basketball most of all.
To talk on the phone is much different from that of face to face.
They fell in love with each other because of common interests.

小公主 The Little Princess 剧本--
Why are they sending so many soldiers daddy, if it is only going to be a little war.
Make those southern boys take us seriously this time, my darlilng.
When they realize how much we want to put a stop to their nonsense, they'll quiet down.
Anyhow, when you get there, you'll stop them won't you daddy?
They'd better.
I'll do my best dear.
We will miss you so.
I'll be back and we'll be together again before you can say knife.
I can say knife a good many times in a year.
At school, you'll have charming little girls to play with.
.books to read, a pony to ride and after all there will be Emily you know.
Yes, there will be Emily.
And she does look as though she'd be an understanding friend,don't you think daddy?
With that intelletual look, I'm sure of it.
- Not a very cheeful looking school, is it daddy?
- I'm afraid nothing would seem very cheerful to us at the moment.
Well, maybe it will be better on the inside.
- Of course it will. I'm sorry sir. - All right, get it out.
- The very idea of delivering a thing like this to the front door.
- Oh look daddy, my pony.
Your employer will answer to this. Now take him away. Yes, far away!
- Oh no daddy. - Oh, I say. Just a moment.
- You are Miss Minchin? - I am.
I'm Captain Crew.
- I'm afraid of caused you no end to inconvenience.
- You most certainly have, Captain Crew.
- May I step inside and explain? - Come in.
- Wait here, I'm returning. - Very well Captain.
-I'm terribly sorry. I had no intention of having the pony delivered inside your house.
- There are a number of things besides the pony.
Parcels have been arriving here collect for your daughter for hours.
Follow me please.
Apparently you are not aware, Captain Crew,
that I conduct one of the most exclusive schools in London.
Yes, yes, I understood.
That is precisely the reason why I brought my daughter to you.
- I would not have gathered that, by your actions.
- Really now, I'm not entirely to blame.
You see Sara and I, only just arrived from India.
Sara has lived there practically all her life.
We no more than got here, when I learned that my regiment was to leave at once for South Africa, so we had to act in a hurry.
But I wrote you and explained that l do not take young ladies without an interview and impecable references.
I wrote you also, that at the moment, I have no vacant room.
- Well in that case daddy, we may as well move on.
- This is a bit awkward.
You see, your letter never reached me
and I'm afraid it never occured to me that any school wouldn't welcome my little Sara.
If it is a question of my social standing,
my father was Sir George Crew. You've heard of him, perhaps?
And the best financial references l can give you
would be the director of the South African Holding Syndicate.
I'm the principal stockholder in the syndicate.
My brother, Captain Crew, a professor of dramatics.
- How do you do? - Charmed, I'm sure.
- I say, isn't the Eclipse Diamond mines one of your holdings?
- One of the most important.
I'm sorry to appear casual Miss Minchin, but the siutation is quite distressing.
I sail in an hour to the east Indian docks.
- I expect you'll just have to take me to Africa with you daddy.
- Well, well and what would a little girl like you do in Africa?
Forgive me Captain Crew. I'm afraid I've been over zealous.
The reputation of my school you know. One has to be so cautious.
But after this interview, I can see at a glance, she's a dear little child.
- It'll be a pleasure to have her with us. - Does that mean I've got to stay?
Yes dear. You are to have that privilege. You and your little pony.
- What a dear little pony. - This is made out to the school.
- Is it enough for the moment.
- Oh quite. - I should say it would. Why it's stupendous.
- I beg your pardon, but haven't I seen you somewhere before?
- Quite possible my dear Captain.
Your face is most familiar.
Were you ever on the stage? I seem to associate you with one of the old music halls.
- Musicals? My brother on the stage? Ridiculous.
- Ridiculous indeed, you're quite right.
And now, shall we look at little Sara's room?
Just a moment Miss Rose.
This is Miss Rose, one of my most capable teachers.
Captain Crew has done us the honor of placing his little daughter Sara with us.
How do you do Miss Rose?
How do you do Captain Crew?
We shall do everything we can to make your little girl happy.
Children, we have a new pupil. Sara Crew. Say how do you do to her.
-How do you do? - I'm very well, thank you.
Lavina, Jesse, that will do. You may proceed Miss Rose.
- She's just like a little princess, isn't she?
- That's what she is, a princess.
I expect now, some people around here won't think they're so smart.
Oh won't they? Wait and see! Princess indeed!
Fortunately, the room has just been papered
and the fireplace has an excellent draft.
- But I thought you didn't have any rooms?
- I didn't know then what a dear little girl was coming.
Why does that make more rooms daddy?
Lady Bengiglis daughter has only recently vacated the room.
Our best suite of course.
Do you think you could brighten it up a bit?
I'd like it made as gay as possible.
I brought a few things from India.
Perhaps you could buy whatever else is necessary

真理是标志主观认识与客观实在相一致的哲学范畴，价值就是客体以自身属性满足主体需要的效益关系，真理和价值是人类活动所追求的两大目标。追求真理是实现价值的基础，实现价值是追求真理的目的，二者统一于人类实践中，并且都要由实践来检验。但是，真理和价值并不总是一致的，如题干就是一个典型例子。

解题思路：（1）红外线是一种不可见光，它在生活中的应用很广泛，可以做成红外线遥控器、红外线探测仪等．电流的迅速变化产生电磁波，且电磁波能相互影响，且能在真空中传播．
（2）光的三基色是红、绿、蓝．如果将磁体放在普通电视机屏幕前，会使图象发生变化．
（3）电视机消耗电能，发出声音、光和热．
电功率的计算，需要根据电能表的物理量计算出电功的大小，然后根据电功率的公式进行计算．

（1）电视机的遥控器可以发出红外线，不同按钮发出红外线的频率是不同的．
我们看到的电视节目信息是通过电磁波传递过来的，手机所能传递信息也是通过电磁波进行传递的，故当正在收看节目的电视机旁边的手机响了，电视机会发出“咔咔”声，这一现象验证了电磁波的存在，同时由于电磁波能在真空中传播，即使把手机放在真空玻璃罩中，电视机仍会受到干扰．

（3）电视机工作的过程中，电能转化为声能、光能、内能．
1KW•h=3.6×10⁶J．
根据电能表的铭牌可知，消耗1KW•h的电能，表盘转3000r．
所以当表盘转15r时，消耗的电能=[15/3000]KW•h=0.005KW•h，合1.8×10⁴J．
2min=120s
根据电功率的公式可得：P=[W/t]=
1.8×104J
120s=150W
故答案为：（1）红外线；频率；电磁波；会．（2）绿；静电．（3）光；内；150．

点评：
本题考点： 红外线；色光的三原色和颜料的三原色；紫外线；物体带电现象；电功的实质；电能表参数的理解与电能的求法；电功率的计算．

考点点评： 本题考点很全，考查学生对红外线、光的三基色、磁现象、电功率计算的掌握情况，难度较大．

孔子(前551年9月28日～前479年4月11日)名丘,字仲尼,春秋末期鲁国人,汉族.英文：Confucius,Kung Tze .中国古代伟大的思想家、政治家、教育家,儒家学派创始人,世界文化名人.孔子的言行思想主要载于《论语》,即语录体散文集及《五经》中.
孔子兄弟排行第二,所以也有人称之为“孔老二”.春秋后期鲁国人.公元前551年9月28日（夏历八月二十七日）生于鲁国陬邑昌平乡（今山东省曲阜市东南的鲁源村）；公元前479年4月11日（农历二月十一日）逝世,享年72岁,葬于曲阜城北泗水之上,即今日孔林所在地.

本题考查的是有关二战的史实。“二战”全面爆发的时间：1939年；建立联合国是雅尔塔会议的重要决定之一；斯大林格勒战役是二战的重要转折点；1945年日本签订投降书，标志着二战结束，所以D项错误。
