有機實驗的八項注意
１.注意加熱方式
有機實驗往往需要加熱，而不同的實驗其加熱方式可能不一樣。
⑴酒精燈加熱。 酒精燈的火焰溫度一般在400～500℃，所以需要溫度不太高的實驗都可用酒精燈加熱。教材中用酒精燈加熱的有機實驗是：“乙烯的制備實驗”、“乙酸乙酯的制取實驗”“蒸餾石油實驗”和“石蠟的催化裂化實驗”。
�、� 水浴加熱。水浴加熱的溫度不超過100℃。教材中用水浴加熱的有機實驗有：“銀鏡實驗（包括醛類、糖類等的所有的銀鏡實驗）”、、“乙酸乙酯的水解實驗（水浴溫度為70℃～80℃）”和“ 糖類（包括二糖、 淀粉和纖維素等）水解實驗（熱水�。�。
�、怯脺囟扔嫓y溫的有機實驗有： “乙酸乙酯的制取實驗”（以上兩個實驗中的溫度計水銀球都是插在反應(yīng)液外的水浴液中，測定水浴的溫度）、“乙烯的實驗室制取實驗”（溫度計水銀球插入反應(yīng)液中，測定反應(yīng)液的溫度）和“ 石油的蒸餾實驗”（溫度計水銀球應(yīng)插在具支燒瓶支管口處， 測定餾出物的溫度）。
２、注意催化劑的使用
�、� 硫酸做催化劑的實驗有：“乙烯的制取實驗”、 “硝基苯的制取實驗”、“乙酸乙酯的制取實驗”、“纖維素硝酸酯的制取實驗”、“糖類（包括二糖、淀粉和纖維素）水解實驗”和“乙酸乙酯的水解實驗”。
其中前四個實驗的催化劑為濃硫酸，后兩個實驗的催化劑為稀硫酸，其中最后一個實驗也可以用氫氧化鈉溶液做催化劑
⑵鐵做催化劑的實驗有：溴苯的制取實驗（實際上起催化作用的是溴與鐵反應(yīng)后生成的溴化鐵）。
３、注意反應(yīng)物的量
有機實驗要注意嚴格控制反應(yīng)物的量及各反應(yīng)物的比例，如“乙烯的制備實驗”必須注意乙醇和濃硫酸的比例為１：３，且需要的量不要太多，否則反應(yīng)物升溫太慢，副反應(yīng)較多，從而影響了乙烯的產(chǎn)率。
４、注意冷卻
有機實驗中的反應(yīng)物和產(chǎn)物多為揮發(fā)性的有害物質(zhì)，所以必須注意對揮發(fā)出的反應(yīng)物和產(chǎn)物進行冷卻。
�、判枰渌ㄓ美淠苁⒀b）冷卻的實驗：“蒸餾水的制取實驗”和“石油的蒸餾實驗”。
�、朴每諝饫鋮s（用長玻璃管連接反應(yīng)裝置）的實驗： “乙酸乙酯的制取實驗”
這些實驗需要冷卻的目的是減少反應(yīng)物或生成物的揮發(fā)，既保證了實驗的順利進行，又減少了這些揮發(fā)物對人的危害和對環(huán)境的污染。
５、注意除雜
有機物的實驗往往副反應(yīng)較多，導(dǎo)致產(chǎn)物中的雜質(zhì)也多，為了保證產(chǎn)物的純凈，必須注意對產(chǎn)物進行凈化除雜。如“乙烯的制備實驗”中乙烯中常含有CO2和SO2等雜質(zhì)氣體，可將這種混合氣體通入到濃堿液中除去酸性氣體。
６、注意攪拌
注意不斷攪拌也是有機實驗的一個注意條件。如“濃硫酸使蔗糖脫水實驗”（也稱“黑面包”實驗）（目的是使?jié)饬蛩崤c蔗糖迅速混合，在短時間內(nèi)急劇反應(yīng)，以便反應(yīng)放出的氣體和大量的熱使蔗糖炭化生成的炭等固體物質(zhì)快速膨脹）、“乙烯制備實驗”中醇酸混合液的配制。
７、注意使用沸石（防止暴沸）
需要使用沸石的有機實驗:⑴ 實驗室中制取乙烯的實驗; ⑵石油蒸餾實驗。

A leading researcher into old age has warned that the dream of living forever, or at least much longer than at present, could turn into a curse（禍根）rather than a blessing. It may become possible to lengthen the 41 human life by controlling genes---but what we gain may not be worth the price we would have to pay.
Professor John Grimley Evens believes that 42 , maximum life expectation is 115, but that with gene 43 it might be possible to extend this. The professor says, however, that a
44 lifestyle can extend the average lifespan of everyone at the moment.
“We know a lot already about how people’s lifestyles 45 their lifespan. There is increasing 46 to suggest that sensible lifestyles are effective in later life as well as in early and middle life.”
“It is never too late to gain some 47 from giving up smoking, from drinking less alcohol, from taking up sensible patterns of diet and exercise and from controlling body weight. We already know how to 48 human life.”
The professor believes that the process of lengthening life by means of gene therapy might bring dangers with it. If gene therapy affected only one part of the human body but not all of it, people might be 49 capable of living longer, but would start to be worse mentally at a much earlier age.
Ⅲ．Reading Comprehension（50分）
Section A（15分）
Directions: For each blank in the following passage there are four words or phrases marked A, B,C or D. Fill in each blank with the word or phrase that best fits the context.
With oil prices approaching the symbolic mark of $ 100 a barrel, the world is heading towards its third energy shock in a generation. But today's rise is 50 different from the oil crises in the 1970s and 1980s. It will have a greater global impact.
The 51 oil shocks were caused by sudden interruptions in exports from the Middle East. But this time prices have been rising steadily as 52 gasoline in both developed countries and developing economies grows. This is the world’s first demand-led energy shock.
Oil prices 53 $ 98.6 on the New York Mercantile Exchange before falling back to $ 96.4 at the close of trading last Wednesday. Forecasts of future oil prices 54 widely. Virtually no one foresees a return to the $20 oil of a decade ago. It means consumers should face an era of high fuel 55 .
For most of the 20th century, 56 was cheap and abundant. Throughout the 1990s,
57 ,oil prices averaged $20 a barrel. Even at today’s highs, luckily, for the Americans, oil is
58 than imported bottle water.
The concern today is over how the 59 sector（行業(yè)）will meet the growth in demand over the longer term.
China faces the 60 . Rapid industrialization has come at a price: Oil demand has increased more than three times since 1980. It turned a country that was once self-sufficient into an oil 61 .
Today, however, China consumes only a third as much oil as the US, which burns a quarter of the 62 oil each day. Europe has managed to reduce oil consumption through high gasoline taxes, small cars and 63 public transportation. But Americans have not.
Experts say no one should count on oil prices rising forever. Economic 64 in the world’s major economies will probably send prices down.

They say there are three ways to experience the Grand Canyon; on foot, on mules（騾子）or by air. We chose the first. Up early; my husband and I and our three children couldn’t wait to get started. We decided to walk along a lovely path named Bright Angel Trail.
As we set out, I was shocked at how narrow the path was. And I couldn’t help noticing that the other tourists weren’t like us. They had heavy backpacks, water bottles, and hats. But as usual we were dressed, As the sun rose higher, Arizona’s famous heat seemed to roast us. There was no shade and our legs were aching. We decided to go back, with the girl on my back and the boys far behind. By the time we finally got back, our legs were like jelly.
The next day, after we’d had a long rest and a good breakfast, we were ready for another view of the Canyon ? by air. After our last walk, this would be the easiest thing in the world.
We called to each other excitedly as the plane took off and circled around the Canyon. But the smiles on our faces disappeared as the pilot tossed（翻轉(zhuǎn)）the plane around, pretending he was going to hit the ground. I shouted, “STOP, TAKE US BACK!” When we finally arrived back on land, once again our legs were like jelly. We hardly spoke as we drove back.
As I said, there are three ways to view the Grand Canyon. We never tried the mules, but personally I’d suggest a fourth: buy yourself a good magazine like National Geographic. That way, you can see the Canyon, without fear or tiredness.
65．Which of the following is true according to the second paragraph?

C．we were dissatisfied D．we were disappointed
67．Which of the following best describes their Canyon trip by air?
A．It proved to be frightening. B．It was more comfortable.
C．It turned out to be exciting. D．It made each of them tired.
68．We can infer from the passage that .
A．experiencing the Canyon on mules would be the best way.
B．one needs to dress less when visiting the Grand Canyon.
C．the writer was not serious when she made the suggestion.

China news, Beijing, Feb. 9 ? Housing price in China has always aroused heated discussions among property developers and ordinary Chinese. To many property developers and local government officials, housing price in China is still low compared with many developed countries. However, the average housing price in the United States is only 8,000 yuan per square meter, while in China, it is even higher than in the United States. This shows that there are some bubbles(泡沫) in Chinese real estate market, the International Finance News reported.
Although the average price of residential houses in the United States, after converted to Renminbi, is about 8,000 yuan per square meter, the houses in US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. If US property developers sell their houses according to the building area, then the housing price will be even lower than 8,000 yuan per square meter. In most big Chinese cities, such as Beijing, Shanghai, and Shenzhen, houses are sold at a price even higher than those in the US.
The high housing sales price in large cities in China proves that Chinese real estate market does have some bubbles. Moreover, Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities. Furthermore, it should be noted that American people’s average income is several dozen times higher than that of Chinese people. How can the Chinese afford to buy a house which is even more expensive than that sold in US?
At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public. Now in order to reduce the high housing prices, the government can regulate the real estate market by raising tax on property industry and controlling the release of loans and lands to property developers. At the same time, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units. By applying these multiple means, it is expected that the high housing prices can be lowered.
72．According to the passage, what is the average housing price per square meter in China?
A．8000 yuan B．10000 yuan C．7000 yuan D．It’s not mentioned here
73．Which of the following does NOT support the idea that the average housing price in China is
even higher than in the United States?
A．Chinese houses can not be compared with houses in US in terms of building quality,
environment and supporting facilities.
B．American people’s average income is several dozen times higher than that of Chinese
people.
C．The houses in US are not sold in terms of building area, as most Chinese property
developers do when they sell their houses.
D．There are more people who need houses in China.
74．What is the main idea of this passage?
A．The housing price in China is so high that the government should do something useful to
prevent it.
B．There are some bubbles in Chinese real estate market.
C．The average housing price in China is even higher than in the United States.
D．Chinese government issued a set of policies that aimed to benefit the public.
75．How many measures are mentioned in the last paragraph in order to reduce the high housing
prices?
A．Four B．Three C．Five D．Two
Some futurologists have assumed that the vast increase of women in the workforce may portend（預(yù)示）a rejection of marriage. Many women, according to this hypothesis, would rather work than marry. The opposite of this concern is that the prospects of becoming a multi-paycheck household could encourage marriage. In the past, only the earnings and financial prospects of the man counted in the marriage decision. Now, however, the earning ability of a woman can make her more attractive as a marriage partner. Data show that economic downturns tend to put off marriage because the parties cannot afford to establish a family or are concerned about rainy days ahead. As the economy comes to life, the number of marriages also rises.
The increase in divorce rates follows to the increase in women working outside the home. Yet, it may be wrong to jump to any simple cause-and-effect conclusions. The impact of a wife’s work on divorce is no less cloudy than its impact on marriage decisions. The realization that she can be a good provider may increase the chances that a working wife will choose divorce over an unsatisfactory marriage. But the reverse is equally plausible（似是而非的）. Tensions grounded in financial problems often play a key role in ending a marriage. By raising a family’s standard of living, a working wife may strengthen her family’s financial and emotional stability.
Psychological factors also should be considered. For example, a wife blocked from a career outside the home may feel caged in the house. She may view her only choice as seeking a divorce. On the other hand, if she can find fulfillment through work outside the home, work and marriage can go together to create a stronger and more stable union.
Also, a major part of women’s inequality in marriage has been due to the fact that, in most cases, men have remained the main breadwinners. A working wife may rob a husband of being the master of the house. Depending upon how the couple reacts to these new conditions, it could create a stronger equal partnership or it could create new insecurities.
76．It is said in the passage that when the economy slides_____.
A．men would choose working women as their marriage partners
B．more women would get married to seek financial security
C．even working women would worry about their marriages
D．more people would prefer to remain single for the time being
77．If women find fulfillment through work outside the home,_____.
A．they are more likely to dominate their marriage partners
B．their husbands are expected to do more housework
C．their marriage ties can be strengthened
D．they tend to put their career before marriage
78．One reason why women with no career may seek a divorce is that_____.
A．they feel that they have been robbed of their freedom
B．they are afraid of being bossed around by their husbands
C．they feel that their partners fail to live up to their expectations
D．they tend to suspect their husbands? loyalty to their marriage
79．Which of the following statements can best summarize the authors view in the passage?
A．The stability of marriage and the divorce rate may reflect the economic situation of the
country.
B．Even when economically independent, most women have to struggle for real equality in
marriage.
C．In order to secure their marriage women should work outside the home and remain
independent.
D．The impact of the growing female workforce on marriage varies from case to case.
Section C（5分）
Directions: Read the following text and choose the most suitable heading form A-F for each paragraph. There is one extra heading which you do not need.
A．A “needs statement” is critical to your proposal.
B．Never write a grant proposal only for funding purpose.
C．About school grants.
D．Read and understand the investor’s guidelines and requirements.
E．Describe your project fully.
F．Let your investor know your progress.
80．
You should always seek grant（獎學(xué)金）opportunities that match your program’s goals and objectives rather than the other way around. If you change your program based on an investor’s guidelines, you may end up with a project or program that is mere shell（框架）of the original plan. The goal of grant writing is not simply to bring more money in for your agency; the goal is to fund programs that will meet the needs of your investor.
81．
Most funding agencies publish grant guidelines or requirements. Make sure you understand them and follow them exactly. Note the deadline and whether the proposal must be received by the deadline. Don’t have your proposal thrown out because you didn’t follow the guidelines properly. Exceptions are rarely made, regardless of the circumstances. Some investors have special requirements; follow them!
82．
Your “needs statement” drives your entire grant proposal. The proposed program should revolve around the problems faced by your clients. The purpose of the grant is to meet the specific needs you have identified. If you have not adequately described the reason you need the program, including the research data when possible, the investor will see no reason to invest in your project.
83．
Every proposal will require a section that describes the broad goals and measurable objectives of your project. You should detail the activities of your project Your budget and budget narrative must closely match the described activities. Your evaluation should carefully measure whether the stated project objectives are being met on a timely basis. Foundation and corporate investors generally expect this section to be no longer than 5 to 10 pages. Federal grants may allow up to 50 pages or more for a thorough discussion of your project. Again, follow the guidelines of the investor.
