The timing of flu season is a little hard to predict. Part of what makes it unpredictable

is that scientists still don t understand exactly why we have one at all. There have been lots of theories: One theory is that people spend more time indoors, with the windows closed, breathing each other s air. Other scientists have argued that cold of winter weakens our immune systems. A third theory is that the flu virus lives in the cold, dry air, but suffers in the warm, humid air. For a while, scientists had a hard time testing these theories: they needed to run experiments, but researchers aren t allowed to infect humans with illnesses, and most lab animals arent affected by the flu the same way people are. In 2007, a medical researcher named Peter Palese found an 80-year-old journal article that reported that guinea pigs (豚鼠)get infected and pass on the flu just like humans. Palese decided to test Theory 3. The research team led by Palese ran several experiments and in each experiment, they injected half the guinea pigs with influenza A (the common flu), and put them in a box next to a box of uninfected animals. At a temperature of 41 degrees, all four of the exposed guinea pigs caught the flu, but when Palese repeated the experiment at 68 degrees, only one of the animals was infected. And when he ran the test at 86 degrees, none of the exposed animals got sick. The researchers also ran experiments where they varied the humidity in the room but kept the temperature constant: the drier the air, they found, the more animals got sick. Palese s study showed that the influenza virus does spread more effectively in cold, dry air.

What does Paragraph 3 mainly discuss？

A．The direction for future research.

B．The necessity of running more tests.

C．The difficulty of testing the theories.

D．The cost of animal experiments.

Economics is the study of how societies with limited resources decide what to produce, how

to produce and for whom to produce. What, how, and for whom to produce are problems all over the world because human wants are practically unlimited, but all societies have only limited quantities of resources that can be used to produce goods or services. A knowledge of basic economics is important for understanding both the problems and opportunities that will face the world economy in the 21st century. As a student of economics, one will have the chance to discover how commerce, government policies, and day-to-day decisions made by consumers affect his living standards. The study of economics can help him understand the influence of such events as the move to free markets in Poland and Russia, or of ups and downs in interest rate and the foreign exchange rate. Economics is influenced by developments in the many different areas of business, politics, science, nature, religion and history. And whether or not one is aware of it, economics is an important part of his life. From a practical point of view, one s study of economics will help improve his decision-making skills. He learns a logical way to compare different courses of action. As he studies the concept of opportunity cost, for instance, he will discover that every choice he makes has both a benefit and a cost. Suppose someone decides to get a part time job so he can earn enough money to buy a car. He will have the benefit of owning the car, but he will pay a cost in terms of the leisure hours he gives up for working so as to pay for the car and keep it in good condition. After weighing his choice in cost-benefit terms, he may decide he does not need a car any more.

According to the passage, economics is studied to______.

A．get more resources for human beings

B．put human wants under some control

C．satisfy the unlimited human wants with the limited resources

D．produce better goods and services for all human beings

根据以下内容，回答题。

Passage Three

Alaska， which was called Russian America before it was sold to U. S. A. ，joined the union as the forty-ninth state in 1959.

Alaska is now the largest of all the 50 states of the U. S..

It was in 1867 that President A. Johnson"s Secretary of State（国务卿），Seward bought Alaska from the Russians at a cost of 7.2 million. The buying of the huge northern land mass seemed at first something foolishly done. Not only was Alaska difficult to reach， but it was also hard to bye in， and it appeared to have no importance in time of war. Besides， there are volcanoes there as Alaska hes on the Pacific" ring of fire". In Alaska large treeless areas are covered with snow all the year. For these reasons the buying of Alaska was called "Seward"s Fooly" at that time.

However， in 1896 gold was found in Alaska， and people poured tin to the land quickly. Since then other important natural resources were discovered， including oil. Soon people changed their thinking about "Seward"s Fooly". But most people visit Alaska in order to see the endless beauty of nature that the northern land discloses to them. For instance， there are a- bout 11，000 islands in Alaska. And in a certain area of Alaska the sun does not set for 82 days

every year.

Alaska belonged to__________before 1867. 查看材料

A.Russia

B.America

C.Canada

D.Japan

根据以下内容回答题：

Every couDle who goes to the altar（圣坛）believes that they will make that trip onlyonce in their lives．They want the day to be perfect，and they are asking for much more than good weather．Thev want the most beautiful clothes，the freshest flowers．Moreover，her family who will foot the bill is not in any mood，to economize． A quick look at any bride magazine will reveal that plenty of attractive goods and services compete for a share of the wedding budget．Besides the obvious choices of rings，dresses，flowers，and photographs，there are the less apparent expenses：a lavish（奢侈的）cake，a rehearsal dinner，a reception，music fbr both the ceremony and the reception，tips，and even nadkins and matchbooks printed with the couple’s names and the wedding date． As the arrangements are generally complicated，there are plenty of services that can be hired to helD with the planning and execution of the every aspect of the wedding：planning the photographs，selecting the wedding rings，choosing the flowers，picking the honeymoon spot，and so on．One magazine lists over 350 such pamphlets published，of course，by businesses who have something to offer．Considering that weddings do more than l 2 billion dollars worth of business annually in the US alone，such activity isn’t surprising． What is surprising is that not one company dominates the industry．It seems that when people plan for a day as special to them as a weddin9，they resist standardization．They turn instead to the small local suppliers known to them or to their friends．Family members or friends often servee as Dhotographers，caterers and musicians．This．not only helps bring the wedding cost down，but makes it more personal． What about the couple that doesn’t want to take in this billion-dollar industry？They can go to eity hall and get married for less than the price of a hamburger．

What does the expression“this billion．dollar industry”refer to？

A.The budgets of weddings．

B.The business ofweddings．

C.The planning and execution of weddings

D.The high wedding expenses．
