The 2009 outbreak of HINI is a new kind of influenza virus, commonly referred to as “swine flu”. It is thought to be a break of four known kinds of influenza. A virus subtype H1N1: one endedmic(流行病) in humans, one endemic in birds, and two endemic in pigs (swine). The source of the outbreak in humans is still unknown, but cases were first discovered in the U.S. and soon after in Mexico.
According to the U.S. Centers for Disease Control and Prevention(CDC),it is not yet clear how serious this new virus actually is compared with other influenza viruses, although on May 26 they stated that new cases in the U.S. have probably reached the hightest point, and most cases have so far been mild relative to “seasonal flus”. But because this is a new virus, most people will not have immunity(免疫性) to it, and illness may eventually become more severe and widspread. The H1N1 flu mainly spreads in the same way that regular “seasonal influenza” spreads through the air from coughs and sneezes or touching those infected. It cannot be transmitted from eating cooked pork or by being in close contact with pigs.
As yet there is no vaccine(疫苗) available to prevent infection although companies are in the planning stages for having one available later this year. But there is concern that the virus could vary again over the coming months, leading to a new and potentially more dangerous flu outbreak later in the year, and a vaccine that will be less effective in preventing its spread.
As of May 27, the virus had spread to more than 50 countries; however, over 80% of reported deaths have taken place in Mexico. According to the CDC, the fact that the flu’s infection activity is now monitored more closely may help explain why more flu cases than normal are being recorded in Mexico, the United States and other countries.    
1. The 2009 outbreak of H1N1 is thought to      .
A.be concerned with four endmics                                             
B.have come from the virus from pigs
C.occur because of unknown virus in Mexico
D.be caused because of people without immunity
2.According to the U.S. Centers for Disease Control and Prevention, ______.
A.most people won’t be infected with the flu                                           
B.the H1N1 will not be too mild to cause many deaths in the world
C.the present situation allows of no optimist
D.H1N1 can be transmitted by touching pigs                             
3.To make people worried more is that      .
A.no effective vaccine can prevent the virus from spreading
B.the virus will mutate in the following months
C.a seasonal influenza will break out
D.the newly-developed vaccine will lose effectiveness
4.From the passage we can learn that      .
A.every country is watching closely the spreading of the H1N1                        
B.more than one-fourth of the deaths from the H1N1 are in Mexico                          
C.only the United States and Mexico recorded the cased of influenza                                                                     
D.effective medicine has been produced to cure the H1N1

New findings suggest that brainy card games such as contract bridge may temporarily(臨時(shí)地) raise production of a key blood cell including in fighting off illness. After 90 minutes of play, bridge players had increased levels of immune(免疫) cells, according to the research reported last week.
A researcher, Diamond, studied bridge players from a women’s bridge club. She chose bridge players because the game includes skills stimulating(刺激) a part of the brain called the dorsolateral cortex. Earlier animal research suggests that this part of the brain may play a role in the immune system.
The findings are based on blood samples drawn from 12 women players. Their blood samples showed a rise in levels of white blood cells called T cells after they played bridge for 90 minutes. T cells are produced by the thymus gland(胸腺) and used by the immune system against diseases.
The T cell count jumped significantly in eight of the bridge players, and slightly in the other four. The findings contribute to the field of neuroimmunology(神經(jīng)免疫學(xué)), whose name reflects the fact that the nervous system and the immune system are not considered separate and isolated(獨(dú)立的) systems. What isn’t clear is whether the help to the immune system from an activity like contract bridge is lasting or temporary. It is also not clear whether the increase in T cells could finally be targeted against special illnesses.
【小題1】Playing bridge can help one to fight off diseases because it can _______.

A.raise production of a key blood cell B.make people joyful
C.a(chǎn)id digestionD.make break away from the bad habits
【小題2】Diamond chose to study bridge players for the research because _______.
A.the players are good friends of hers
B.she loves playing bridge
C.this game stimulates a part of the brain that has something to do with immune system
D.she is a clever manager, who operates her bridge club well
【小題3】A T cell is _______ cell.
A.a(chǎn) brainB.a(chǎn) white blood
C.a(chǎn) red blood D.a(chǎn) kind of dangerous blood
【小題4】Which of the following is true according to this article?
A.The immune system and the brain system used to be considered separate and isolated systems.
B.The help to the immune system that is brought about by playing bridge can last for a long time.
C.Cortex is a kind of blood cell.
D.The new findings are impossible.

科目:高中英語(yǔ) 來(lái)源:2010年江西省高一上學(xué)期期中考試英語(yǔ)卷 題型:閱讀理解

The industrial age has been the only period of human history in which most people’s work has taken the form of jobs. The industrial age may now be coming to an end, and some of changes in work patterns which it brought may have to be reversed. This seems a discouraging thought. But, in fact, it could offer the prospect of a better future for work. Universal employment, as its history show, hasn’t meant economic freedom.

Employment became widespread when the enclosures(圈地運(yùn)動(dòng))of the 17th and 18th centuries made many people dependent on paid work by taking them away from the use of the land, and thus from the means to provide a living for themselves. Then the factory system destroyed the cottage industries and removed work from people’s homes. Later, as transport improved, first by rail and then by road, people traveled longer distances to their place of employment until, eventually, many people’s work lost all connection with their home lives and the places in which they lived.

Meanwhile, employment put women at a disadvantage. In pre-industrial times, men and women had shared the productive work of the household and village community. Now it became customary for the husband to go out to paid employment, leaving the unpaid work of the home and family to his wife. Tax and benefit regulations still assume this norm(準(zhǔn)則)today, and restrict more flexible sharing of work roles between sexes.

It was not only women whose work status suffered. As employment became the dominant form of work, young people and old people were kept out — a problem now, as more teenagers disappointed and annoyed at school and more retired people want to live active lives.

All this may now have to change. The time has certainly come to switch some efforts and resources away from the utopian(烏托邦)goal of creating jobs for all, to the urgent practical task of helping many people to manage without full-time jobs.

1. From the passage we can learn that ____.

A.jobs have existed since human came into being

B.the industrial age brought jobs to everyone

C.the industrial age brought the work patterns most people’s work has taken

D.in the future more and more people could get jobs as the industry is developing

2.Before the enclosures of the 17th and 18th, people lived mainly on ____.

A.paid work

B.unpaid work

C.taxes and benefits

D.land

3.Before the industrial age women played ____.

A.more important roles in making a life

B.less important roles in making a life

C.roles as weak as after in raising their children

D.roles as important as men in supporting a family

4. From the passage we can infer that ____.

A.creating jobs for all must be changed

B.enough jobs must be created by our society

C.more and more jobs are being created

D.industrial age has made many people unable to live without full-time jobs
