Thinking Human emotion is one of those factors that cannot he definedexactly. The reason is that it is quite uncertain. We cannot change thefeelings that are roused when we experience different things.
(26)Some people forget that they arc in control. They make their choicesbased on their emotions. I hey experience failure and loss and let theiremotions rule their decisions. They are trapped in their sadness and thus. experience more failure. Some people say they need a lucky break to recover from 、theirfailures.
(27) They need to get over their failures on their own. But how do they dothat？ I he answer is: positive thinking. People often fail to realize the power of positive thinking.
(28 )Theyfail to realize that they only need to overcome their fears in order to trulysucceed in life. They just have too much pride and are blinded of theirown shortcomings. The power of positive thinking lies in belief.
(29)You make thedecisions that affect your life. You may not be able to change yourenvironment, but you are able to change the way you react to it. The power of positive thinking lies beyond false courage. You need lotake another look at the world around you.
(30)You can&39;t rest on yoursuccess. or foolish pride will cause you to make wrong decisions. They fail to realize that their worst enemy lies within themselves. However. we must always remember that we can control ourreactions. You can’t just take a look at your failures, or you will lose hope.
D. We can benefit a lot from positive thinking.
E.However, life rarely gives people a break.
F.You need to believe that you arc in control.

The demand for foreign exchange can be either transaction or speculative based. The transactions demand for foreign exchange comes from those who wish to make payment to a foreign country for the purchase of a good，a service，or a security purchased from a resident of，or a company located in a foreign country．A resident of the United States wishing to make a remittance to a relative in the United Kingdom would also affect the demand for sterling. The same would be true if the resident of one country wished to make a contribution to a charity located in another country．Speculative demand for a currency is generated by the confidence speculators have in that currency vis-à-vis other world currencies．This demand could be based on political and/ or economic factors，as demonstrated during the 1970s．For example，when the mark was strong and the sterling weak，speculators would sell sterling to buy marks．
The supply of foreign exchange is provided by those who are willing to sell a currency they hold．This may include those who will receive payments in a foreign currency for the export of goods and services，the sale of securities to foreign residents，or the receipt of foreign exchange resulting from gifts or contributions made by foreign countries．International speculators arc also sources of supply when they feel the currency they hold is weak relative to other world currencies．

If an economist were asked which of three groups borrow must people with rising incomes, stable incomes, or declining incomes—he would probably answer: those with declining incomes. Actually, in the years 1947 -1950, the answer was: people with rising incomes. People with declining incomes were next and people with stable incomes borrowed the least. This shows us that traditional assumptions about earning and spending arc not always reliable. Another traditional assumption is that if people who have money expect prices to go up, they will hasten to buy. If they expect prices to go down, they will postpone buying. But research surveys have shown that this is not always true. The expectations of price increases may not stimulate buying. One typical attitude was expressed by the wife of a mechanic in an interview at a time of rising prices. "In a few months," she said, "we'll have to pay more for meat and milk; we'll have less to spend on other things." Her family had been planning to buy a new car but they postponed this purchase. Furthermore, the rise in prices that has already taken place may be resented and buyer's resistance may be evoked. This is shown by the following typical comment:" I just don't pay these prices; they are too high."
Traditional assumptions should be investigated carefully, and factors of time and place should be considered. The investigations mentioned above were carried out in America. Investigations conducted at the same time in Great Britain, however, yielded results that were more in agreement with traditional assumptions about saving and spending patterns. The condition most conducive to spending appears to be price stability. If prices have been stable and people have become accustomed to consider them "right" and expect them to remain stable, they are likely to buy. Thus, it appears that the common business policy of maintaining stable prices with occasional sales or discounts is based on a correct understanding of consumer psychology.
The best title of the passage is ______.
A．Consumer's Purchasing Power
B．Relationship between Income and Purchasing Power
C．Traditional Assumptions
D．Studies in Consumer Behavior
I've just spent a few days in Paris and have returned home without a single picture of the Eiffel Tower, the Arc de Triomphe or Notre Dame.

It's not unreasonable to ask why taking a photograph of wet cobblestones should be more 【C9】______ to me than shooting a beautiful building like Notre Dame.

Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D . Mark your answers on ANSWER SHEET 1.
Most growing plants contain much more water than all other materials combined. C. R. Barnes has suggested that it is as proper to term the plant a water structure as to call a house composed mainly of brick a brick building. Certain it is that all essential processes of plant growth and development occur in water. The mineral elements from the soil that arc usable by the plant must be dissolved in the soil solution before they can be taken into the root. They are carried to all parts of the growing plant and are built into essential plant materials while in a dissolved state. The carbon dioxide (CO2 ) from the air may enter the leaf as a gas but is dissolved in water in the leaf before it is combined with a part of the water to form. simple sugars --'the base material from which the plant body is mainly built. Actively growing plant parts are generally 75% to 90% water. Structural parts of plants, such as woody stems no longer actively growing, may have much less water than growing tissues.
The actual amount of water in the plant at ashy one time, however, is only a very small part of what passes through it during its development. The processes of photosynthesis, by which carbon dioxide and water are combined -- in the presence of chlorophyll and with energy derived from light- to form. sugars, require that carbon dioxide from the air enter the plant. This occurs mainly in the leaves. The leaf surface is not solid but contains great numbers of minute openings, through which the carbon dioxide enters. The same structure that permits the one gas to enter the leaf, however, permits another gas -- water vapor -- to be lost from it. Since carbon dioxide is present in the air only in trace quantities (3 to 4 parts in 10,000 parts of air) and water vapor is near saturation in the air spaces within the leaf (at 80°F, saturated air would contain about 186 parts of water vapor in 10,000 parts of air), the total amount of water vapor lost is many times the carbon dioxide intake. Actually, because of wind and other factors, the loss of water in proportion to carbon dioxide intake may be even greater than the relative concentrations of the two gases. Also, not all of the carbon dioxide that enters the leaf is synthesized into carbohydrates.
A growing plant needs water for all of the following EXCEPT ______.
A．forming sugars
B．sustaining woody stems
C．keeping green
D．producing carbon dioxide
Passage one
The factors that add up to a happy life for most people are not what we typically hear about. Things like earning a master’s degree don’t make people happy over an extended period of time. Rather, the key to happiness, and the difference between happy and unhappy Americans, is a life that reflects values and practices like, hard work, marriage, charity, and freedom.
Work
When more than 1,000 people across the country were asked in 2002, "If you were to get enough money to live comfortably for the rest of your life, would you stop working？" fewer than a third of the Americans answered yes. Contrary to widely held opinion, most Americans like or even love their work. In 2002 an amazing 89 percent of workers said they were very satisfied or somewhat satisfied with their jobs. This isn&39;t true just for those with high-paying, highly skilled jobs but for all workers across the country. And the percentage is almost exactly the same among those with and without college degrees and among those working for private companies, nonprofit organizations, and the government. For most Americans, job satisfaction is nearly equivalent to life satisfaction. Among those people who say they are very happy in their lives, 95 percent are also satisfied with their jobs. Furthermore, job satisfaction would seem to be causing overall happiness, not the other way around.
Marriage & Family
In 2004, 42 percent of married Americans said they were very happy. Just 23 percent of never-married people said this. Overall, married people were six times more likely lo say that they were very happy than to report that they were not too happy. And generally speaking, married women say they&39;re happy more often than married men.
Marriage isn’t just associated with happiness --it brings happiness, at least for a lot of us. One 2003 study that followed 24,000 people for more than a decade documented a significant increase in happiness after people married. For some, the happiness increase wore off in a few years, and they ended up back at their premarriage happiness levels. But for others, it lasted as long as a lifetime. What about having kids？ While children, on their own, don&39;t appear to raise the happiness level (they actually tend to slightly lower the happiness of a marriage), studies suggest that children arc almost always part of an overall lifestyle. of happiness, which is likely to include such things as marriage and religion. Charity We&39;ve all heard that money doesn&39;t buy happiness, and that’s certainly true. But there is one way to get it: Give money away.
The evidence is clear that gifts to charitable organizations and other worthy causes bring substantial life satisfaction to the givers. If you want $50 in authentic happiness today Just donate it to a favorite charity. People who give money to charity are 43 percent more likely than nongivers to say they&39;re very happy. Volunteers are 42 percent more likely to be very happy than nonvolunteers. It doesn’t matter whether the gifts of money go to churches or concerts; religious giving and unreligious giving leave people equally happy, and far happier than people who don&39;t give. Even donating blood, an especially personal kind of giving, improves our attitude. Fundamentally, the more people give, the happier they get.
Freedom
In fact, freedom and happiness are intimately related: People who consider themselves free are a lot happier than those who don&39;t. In 2000 the General Social Survey revealed that people who personally feel "completely free" or "very free” were twice as likely as those who don&39;t to say they’re very happy about their lives. Not all types of freedom are the same in terms of happiness, however. Researchers have shown that economic freedom brings happiness, as does political and religious freedom. On the other hand, moral freedom ----a lack of constraints on behavior. ----does not. People who feel they have unlimited moral choices in their lives when it comes to matters of sex or drugs, for example, tend to be unhappier than those who do not feel they have so many choices in life.
Lessons for America
The data tell us that what matters most for happiness is not having a lot of things but having healthy values. Without these values，our jobs and our economy will bring us joyless riches. The facts can help remind us of what we should be paying attention to, as individuals and as families, if we want to be happy. Our happiness is simply too important to us -- and to America -- to do anything less.
What will probably bring about overall happiness？
A.To be satisfied with one’s job.
B.To earn a lot of money.
C.To work for big companies.
D.To gain a college degree.
Generally, men in marriage _____ than women in marriage.A.are probably under greater pressure
B.are more inclined to feel they are happy
C.are less likely to state they arc happy
D.are contributing more to the family
According to the author, in what way can money bring happiness？A.Buy anything you want.
B.Give your money away.
C.Pay to listen to a concert.
D.Own a large amount of it.
What rarely brings in happiness？A.Religious freedom.
B.Economic freedom.
C.Political freedom.
D.Moral freedom.

Early investigators correctly reasoned that the structural similarity to the serotonin molecule might imply that LSD' s effects arc brought about by an action on the neurotransmission of serotonin in the brain. Unfortunately, the level of technical expertise in the field of brain research was such that this hypothesis had to be tested or, peripheral tissue (tissue outside the brain). Two different groups of scientists reported than LSD powerfully blockaded serotonin' s action, their conclusions were quickly challenged, however. We now know that the action of a drug at one site in the body does not necessarily correspond to the drug' s action at another site, especially when one site is in the brain and the other is not.
By the 1960' s technical advances permitted the direct testing of the hypothesis that LSD and related hallucinogens act by directly suppressing the activity of serotonin secreting neurons themselves—the so called presynaptic hypothesis. Researchers reasoned that if the hallucinogenic drags act by suppressing the activity of serotonin-secreting neurons, then drugs administered after these neurons had been destroyed should have no effect on behavior, because the system would already be maximally suppressed. Contrary to their expectations, neuron destruction enhanced the effect of LSD and related hallucinogens on behavior. Thus hallucinogenic drugs apparently do not act directly on serotonin-secreting neurons.
However, these and other available data do support an alternative hypothesis, that LSD and related drugs act directly at receptor sites on serotonin target neurons (the postsynaptic hypothesis). The fact that LSD elicits "serotonin syndrome", that is, causes the same kinds of behaviors as does the administration of serotonin in animals whose brains are depleted of serotonin indicates that LSD acts directly on serotonin receptors, rather than indirectly through the release of stores of serotonin. The enhanced effect of LSD reported after serotonin depletion could be due to a proliferation of serotonin receptor sites on serotonin target neurons. This phenomenon often follows neuron destruction or neurotransmitter depletion; the increase in the number of receptor sites appears to be a compensatory response to decreased input. Significantly, this hypothesis is supported by number of different laboratories
According to the passage, which of the following is one of the primary factors that led researchers studying hallucinogenic drugs to focus on serotonin？
A．The suppression of the activity of serotonin-secreting neurons by the administration of hallucinogens.
B．The observed similarities in the chemical structures of serotonin and hallucinogens.
C．The effects the administration of hallucinogens has on serotonin production in the human brain.
D．Serotonin-induced changes in the effects of hallucinogens on behavior.
