A.②③④          B.②③④⑤       C.①③④      D.①②③④

2、科學家在多年前就探測到火星大氣中存在微量的羰基硫(COS),已知能發生下列反應:

CO+S COS,2COS +SO22CO2 +S,運用這兩個反應可以

A.證明地球上也存在COS               B.消除CO、SO2的污染

C.消除溫室效應                                D.回收硫

 

3、鋁土礦(主要成分Al2O3、雜質Fe2O3和SiO2)是冶煉金屬鋁的主要礦石原料。據統計,按目前鋁的消費速度,已探明的鋁土礦僅能維持30年左右。因此保護鋁資源和回收利用廢舊鋁具有十分重要的意義。

(1)、目前廢舊鋁的回收利用很不理想,你認為回收鋁過程中存在的主要困難有哪些?(任寫三條)

 

 

 

 

 

 

 

 

 

 

(2)、常溫下,SiO2與強堿或強酸反應反應速率很慢。現利用鹽酸、氫氧化鈉溶液、氨氣、二氧化碳和水中的某些物質,從鋁土礦中提取純凈的 Al2O3。試設計一個簡單適用的提純方案,用化學方程式表示提純的過程。

 

 

 

 

 

 

 

 

 

 

 

 

 

3、工業上通過電解氧化鋁和冰晶石熔融混合物生產鋁。已知一個電子的電量約為1.6×1019C。計算:制取2.7kgAl理論上需要多少庫侖的電量?

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

4、已知:

 

請根據題示信息,模仿上述流程圖設計合成路線,用苯酚為主要原料合成 ,標明每一步的反應物及反應條件。(有機物寫結構簡式,其它原料自選)。

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

5、用釀造的C2H5OH作燃料,為何不會增加大氣中CO2的含量?請用學過的知識加以解釋。

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

6、現行教材(試驗修訂本)第二冊(必修加選修)中關于銀鏡反應實驗的操作為:向2%的AgNO3溶液里逐滴滴加2%的稀氨水,至生成的沉淀恰好溶解,這時所得的溶液叫銀氨溶液。再滴加幾滴乙醛,振蕩后水浴加熱,觀察現象。教材所給的化學方程式為:

                                                               

你認為這個化學方程式科學嗎?如果不科學,請簡要說明并改正。

    Father's Day is a fairly new celebration in the British calendar compared with Mother's Day, which has been a very popular and well celebrated festival in the UK for a very long time.

    Father’s Day was first celebrated by American  36  it was inspired by the actions of a man named William Smart. He was a veteran(退伍軍人)of the US Civil War and his wife          37   away giving birth to their sixth child. He  38  six children alone without remarrying, which was undoubtedly   39   back in those days.

    His daughter, Sonora Dodd,  40  when she was an adult what her father had sacrificed for his  41  . It was in the early 1900s and she was actually  42   one day, listening to a sermon(傳教) on   43  . She thought there should   44   be a Father's Day celebration.

    And so the   45   was born, on the third Sunday every June, close to the anniversary of Sonora's father's death. Britain took the idea of Father's Day from the American celebration and it has been celebrated   46   since the 1970s.

    Father's Day is never quite such the big commercial event   47   Mother's Day is, probably because it hasn't been in   48   for so long. But what do British people do for Father's Day?

    Well, most people would buy their fathers a card. The card would probably have a nice message in it   49  what a great Dad their father is. Some people do buy presents as well.

    50   gifts for Dads are probably ties, chocolates or socks because these are things that Dads can  51   use even if they don't want them. In the run-up(即將到來之際) to Father's Day, or indeed Mother's Day, there will be ads on the TV giving  52  ideas of CDs or gadgets (小玩具,小玩意)we can buy. Card shops will be full of mugs or pens and similar goods with “World's Greatest Dad”  53   on them.

    Some families   54  do things together to celebrate Father's Day like going for a meal. As a special treat, British people might give their Dad a bit of a rest ,  55   him a cup of tea, or even wash his car and mow the lawn(除草) to make him feel really appreciated.

    I am one of the many city people who are always saying that given the choice we would prefer to live in the country away from the dirt and noise of a large city. I have managed to convince myself that if it weren’t for my job I would immediately head out for the open spaces and go back to nature in some sleepy village buried in the country. But how realistic is the dream?

    Cities can be frightening places. The majority of the population live in massive tower blocks, noisy, dirty and impersonal. The sense of belonging to a community tends to disappear when you live fifteen floors up. All you can see from your window is sky, or other blocks of fiats.

    Strangely enough, whereas in the past the inhabitants of one street all knew each other, nowadays people on the same floor in tower blocks don’t even say hello to each other.

    Country life, on the other hand, differs from this kind of isolated(隔離)existence because  a sense of community generally ties the inhabitants of small villages together. But country life has disadvantages too. It is true that you are cut off from the exciting and important events that take place in cities. There’s little possibility of going to a new show or the latest movie. Shopping becomes a major problem, and for anything slightly out of the ordinary you have to go on an expedition to the nearest large town. The city-people who leave for the country are often oppressed by a sense of unbearable stillness and quietness.

    What , then , of my dreams of leaning on a cottage gate and murmuring “morning” to the locals as they pass by? I’m eager for the idea, but you see there’s my cat, Toby. I’m not at all sure that he would take to all that fresh air and exercise in the long grass. I mean, can you see him mixing with all those hearty males down the farm? No, he would rather have the electric fire any evening.

    On the afternoon of September 27,2008 ,astronaut Zhai Zhigang became the first Chinese man to walk in space on Saturday, clambering(攀爬) out of China's Shenzhou VII space craft in a technological feat(成就) that made the Chinese people excited.

    "I'm feeling quite well. I greet the Chinese people and the people of the world," Zhai said as he climbed out of the craft at around 16:40 Beijing time, a historic achievement telecast live on CCTV. Tens of millions of Chinese viewers gathered before TV screens to watch the moment.

    Chinese President Hu Jintao and other top leaders had appeared at the Beijing Aerospace Control Center to watch the live transmission of Zhai's space walk.
         Zhai, 42, chosen by an expert team for the first "out-of -capsule activity," showed a red national flag, helped by colleague Liu Boming, who also briefly popped his head out of the capsule.
         Zhai slowly made his way towards a test sample of solid lubricant(潤滑劑) outside the capsule, took a sample and handed it to Liu.
         Zhai safely returned inside the craft after about 20 minutes. The walk marked the highpoint of China's third manned space journey, which has received widespread media coverage.學科網(Zxxk.Com)
        Zhai wore a $4.4 million Chinese-made suit weighing 120-kg. Liu wore a Russian-made one and acted as an assistant.

    The third crew member, Jing Haipeng, monitored the ship from inside the re-entry module.

    The risky maneuver is a step towards China's longer-term goal of building a space lab and then a larger space station, analysts said.

    "On this flight, Chinese people's footprints will be left in space for the first time," said a commentary by the Xinhua news agency.

    The astronauts went abroad on their walk after receiving a clean bill of health from doctors on the ground at mission control in Beijing, Xinhua said.

    Zhai's suit has 10 layers and takes up to 15 hours to assemble and put on.

    China's first manned spaceflight was in 2003. A second, two-manned flight followed in 2005. The only other countries that have sent people into space are Russia and the United States.

    Shenzhou VII took off on Thursday and is due to land on the northern steppes (草原)of Inner Mongolia on Sunday.

    71. The space walk done by the Chinese astronaut was historic because_______.

    A. it was telecast live  

    B. there were more Chinese viewers than ever

    C. it was the first space walk carried out by Chinese astronauts

    D. top leaders watched the space walk

    72. The following statements are true EXCEPT________.

      A. the lubricant put outside the capsule was a test sample

      B. it took Zhai Zhigang about 20 minutes to return to the craft safely

    C. many televisions and newspapers around the world reported the event

    D. there is an aerospace control center in the capital

    73. The significance of the space walk is that _________.

      A. the astronaut can work outside the spacecraft

      B. it marks a successful step towards China’s longer-term goal of building a space lab as well as a space station

    C. it has attracted tens of millions of people to watch the walk

    D. the Chinese-made space suit can be used in space

    74. What does the underlined word “clean” mean in the passage?

      A. Healthy      B. Paid-off     C. Not dirty      D. Clear

    75. The best title of the passage is ________ .

      A. First Footprints of Chinese People in Space

    B. Expensive Space Suit

    C. Three Successful Manned Flights by Chinese Astronauts

    D. Historic Space Walk by Chinese Astronaut
