Face Masks May Not Protect from Super-flu
1 If a super-flu strikes,face masks may not protect you.Whether widespread use of masks will help,or
harm,during the next worldwide flu outbreak is a question that researchers are studying furiously.No results
have come from their mask research yet.However,the government says people should consider wearing them
in certain situations anyway,just in case.
2 Butit's a question the public keeps asking while the governments are making preparations for the
next flu pandemic. So the Centers for Disease Control and Prevention ( CDC ) came up with（提出）prelimi-
nary guidelines（初步指导方针）." We don ' t want people wearing them everywhere,"said the CDC. " The
overall recommendation really is to avoid exposure."
3 When that'S not possible,the guidelines say to consider wearing a simple surgical mask if you are in
one of the three following situations.First,you're healthy and can't avoid going to a' crowded place.Second,
you're sick and think you may have close contact with the healthy,such as a family member checking on
you.Third,you live with someone who'S sick and thus might be in the early stages of infection,but still need
to go out.
4 Influenza pandemic can strike when the easy-to-mutate flu virus shifts to a strain that people never
have experienced.Scientists cannot predict when the next pandemic will arrive,although concern is rising
that the Asian bird flu might trigger one if it starts spreading easily from person to person.
5 During the flu pandemic,you should protect yourself. Avoid crowds,and avoid close contact with the
sick unless you must care for someone.Why aren't masks added to this self-protection list?Because they can
help trap virus-laden（含有病毒的、充满细菌的）droplets flying through the air with a cough or sneeze.
Simple surgical masks only filter the larger droplets.Besides,the CDC is afraid masks may create a false
sense of security.Perhaps someone who should have stayed home would don an ill-fitting mask and hop on
the subway instead.
6 Nor does flu only spread through the air. Say someone covers a sneeze with his or her hand,then tou--
ches a doorknob or subway pole.If you touch that spot next and then put germy hands on your nose or
mouth,you'ye been exposed.It's harder to rub your nose while wearing a mask and so your face may get
pretty sweaty under masks.You reach under to wipe that sweat,and may transfer germs caught on the outside
of the mask straight to the nose.These are the problems face masks may create for their users.
7 Whether people should or should not use face masks still remains a question.The general public has
to wait patiently for the results of the mask research scientists are still doing.

Health Promotion
1 World health will improve only if the people themselves become involved in planning,
implementing,and having a say about their own health and health care.But involvement
will not just happen.
2 How serious are we about involving individuals,families,and communities?Are we
prepared一mentally and professionally（专业上）一to listen to their concerns,to learn from
them what they feel is important,to share with them appropriate information,to encourage
and support them?In many cases,so far,the answer is"No".We can go on and on
developing plans:nothing will happen unless all health workers,all health managers,and
key professionals（专业人员）in other areas come to realize what is at stake. To overcome
these particular stumbling一blocks（障碍物）,I see three major requirements.
3 First,health workers must understand that the concept of primary health care involves
new roles for them , and a new outlook（观点）.Not only should we be concerned with
disease prevention and control,we must also be concerned with health promotion and care,
and not least with development in general一and with people.Our health technologies must
be based on what the people themselves want and need.
4 Second,health workers must accept their new roles.More yet:they must be keen to
try them out,to broaden their scope and to innovate（创新）in the partnership（合伙人、合
作关系）approach. Their main concern must be to find ways of helping individuals and
communities become self-dependent.
5 This brings me to my third point:health workers must have the necessary skills to
perform these new roles effectively and to make efficient use of existing knowledge.This
calls for a training force fully familiar with previous experience and keen to provide the kind
and quality of professional preparation needed.It also calls for full support from health
manaqers for such traininq.
Health workers cannot perform their new roles effectively without_________.
A: some stumbling-blocks

Working for Fun and Profit
1.It's a sunny weekend morning. You decide to take a walk.Everything is quite except for a.group of people and some colorful objects you see about three blocks away.As you get closer,you notice that there are many things lying on the ground:some National Geographic magazines,a collection of toy trucks,some weight lifting equipment,two bicycles,and a set of chairs.People are parking cars,getting out,and looking over the objects in the driveway.You consider taking a detour around the group of people,but you are curious.Was there an accident?Is this a party?No!Welcome to your first garage sale!
2.On the same morning,a friend of yours takes a drive.He makes a mistake at an intersection and takes a wrong turn.He passes a large parking lot full of people,not cars.He sees many multicolored objects.At first he thinks it's an art show. Then he decides it's a fair. He parks his car and gets out to explore.He's just arrived at his first flea market.
3.Garage sales and flea market are popular in the United States.Many Americans find that they can make a little extra money and have fun being"weekend entrepreneurs”.They take outgrown clothing,appliances,toys,and books and resell them at garage sales and flea markets.
4.Flea markets are generally open spaces in or out of town that become busy sales centers on weekends.People who want to sell new or used clothing,tools,furniture,or books rent a space for the day for a small amount of money and sell their merchandise.Shoppers from near and far come to get good buys on imported watches,house plants,magazines,microscopes,children's clothes,and handmade goods such as embroidered pillowcases or jewelry.Some shoppers even buy and sell antiques.They search flea markets for special treasures that they can resell in their own stores for lots of money.
5.Garage sales are smaller than flea markets,and the merchandise consists mainly of household items.Dishes,pots and pans,coat hangers,and children's clothing are inexpensive and common at garage sales. People frequently have garage sales before they move and on weekends when the weather is nice.Sometimes several families gather their unwanted household goods and sell them together. More merchandise attracts more customers.

Messages from the Media
1. The weather forecast,a story about the candidates in an election,and movie reviews are exam-ples of messages from the media. A communication medium , of which the plural（复数的）form is
media,is a means of communicating a message .Examples of media are television,radio,news-pa-pers and books and the telephone.The media that can reach many people at once are called mass media.
2. It is not difficult to think of other messages we receive through the mass media.Every day we get hundreds of them.Think about advertisements,for example.We see and hear these messages almost everywhere we go .Advertisements are important messages,even though they are sometimes annoying .They help us compare and evaluate products.
3. Most of us get more information from the media than from the classroom.Think for a moment, about how you learn about local news and events.Do you depend on other people or the media?
What about international news?What is the most important source of information for you?People who are asked this question usually answer,"Television".
4. Think of all the messages you received today.Perhaps you read a newspaper during breakfast, or maybe you read advertisements on billboards（露天广告牌）on your way to school. Did you u1sten to a weather forecast or the sports news on the radio this morning?Right now you are getting information through a very important medium of mass communication a book.
5. We use the information we get from radio,television,newspapers,and other media to make decisions and form opinions.That is why the mass media are so important.Editorials and articles in newspapers help us decide how to vote,consumer reports on television help us decide how to spend our money,and international news on the radio makes us think and form opinions about question of war and peace.

“Life Form Found" on Saturn ' s Titan
Scientists say they have discovered hints of alien life on the Saturn'5 moon.The discovery of a sort of
life was announced after researchers at the US space agency,NASA,analyzed data from spacecraft Cassini,
which pointed to the existence of methane-based form of life on Saturn's biggest moon.
Scientists have reportedly discovered clues showing primitive alien beings are"breathing"in Titan's
dense atmosphere filled with hydrogen.
They argue that hydrogen gets absorbed before hitting Titan's planet-like surface covered with methane
lakes and rivers.This,they say,points to the existence of some"bugs"consuming the hydrogen at the surface
of the moon less than half the size of the Earth.
"We suggested hydrogen consumption because it's the obvious gas for life to consume on Titan,similar
to the way we consume oxygen on Earth,"says NASA scientist Chris McKay."If these signs do turn out to be
a sign of life,it would be doubly exciting because it would represent a second form of life independent from
water-based life on Earth."
To date,scientists have not yet detected this form of life anywhere,though there are liquid-water-based
microorganisms on Earth that grow well on methane or produce it as a waste product. On Titan,where
temperatures are around minus 17 Kelvin(minus 290 degrees Farenheit),a methane-based organism would
have to use a substance that is liquid as its medium for living processes,but not water itself. Water is frozen
solid on Titan'5 surface and much too cold to support life as we know it.
Scientists had expected the Sun'5 interactions with chemicals in the atmosphere to produce a coating of
acetylene on Titan'5 surface.But Cassini detected no acetylene on the surface.
The absence of detectable acetylene on the Titan's surface can very well have a non-biological explana-
tion,said Mark Allen,a principal investigator of the NASA Titan team.
"Scientific conservatism suggests that a biological explanation should be the last choice after all non-
biological explanations are addressed,"Allen said."We have a lot of work to do to rule out possible non-bio-
logical explanations.It is more likely that a chemical process,without biology,can explain these results."
Which of the following statements about Titan is true?
A:It is as large as the Earth.
B:There is acetylene on its surface.
C:Water on it acts as a life supporting medium.
D:Hydrogen consumption is reported to be on it.

Rising College Selectivity
Rising college selectivity doesn't mean that students are smarter and more serious than in the past.It's a function of excess demand for higher education,occurring at a time of increased financial privatization of the industry.
The recession has only increased demand.The vast majority of students aren't going to college because of a thirst for knowledge.They're there because they need a job,and they need to get the credentials（证书）and one hopes, the knowledge and skills behind the credentials一that will get them into the labor market.
As higher education has become a seller's market,the institutions in a position to do so are doing what comes naturally:raising their tuitions and their admissions requirements,but at the expense of contributing to the national goal to increase college attainment.The result is that the United States is losing ground in the international race for educational talent.
The increasing stratification（阶层化）of higher education is happening on the spending side, as well.As the selective institutions have become more expensive and less attainable,the rest have had to struggle with the responsibility to enroll more students without being paid to do so.Gaps be-tween rich and poor have grown even more dramatically than gaps in entering test scores.While spending is a poor measure of educational quality,we can't seriously expect to increase educational attainment if we're not prepared to do something to address these growing inequities in funding.
That said,the educational policy problem in our country is not that the elite institutions are becoming more selective.The problem is on the public policy side.The president and many governors have set a goal to return America to a position of international leadership in educational attainment.
It's the right goal,we just need a financing strategy to get there.That doesn't mean just more money,although some more money will be needed.It also means better attention to effectiveness and to efficiency,and to making sure that spending goes to the places that will make a difference in educational attainment.We know how to do it,if we want to.
What does the author think should be modified?
A:The selectivity of elite institutions.
B:The industrialization of education.
C:The goal of education attainment.
D:The government's funding strategy.

Rising College Selectivity
Rising college selectivity doesn't mean that students are smarter and more serious than in the past.It's a function of excess demand for higher education,occurring at a time of increased financial privatization of the industry.
The recession has only increased demand.The vast majority of students aren't going to college because of a thirst for knowledge.They're there because they need a job,and they need to get the credentials（证书）and one hopes, the knowledge and skills behind the credentials一that will get them into the labor market.
As higher education has become a seller's market,the institutions in a position to do so are doing what comes naturally:raising their tuitions and their admissions requirements,but at the expense of contributing to the national goal to increase college attainment.The result is that the United States is losing ground in the international race for educational talent.
The increasing stratification（阶层化）of higher education is happening on the spending side, as well.As the selective institutions have become more expensive and less attainable,the rest have had to struggle with the responsibility to enroll more students without being paid to do so.Gaps be-tween rich and poor have grown even more dramatically than gaps in entering test scores.While spending is a poor measure of educational quality,we can't seriously expect to increase educational attainment if we're not prepared to do something to address these growing inequities in funding.
That said,the educational policy problem in our country is not that the elite institutions are becoming more selective.The problem is on the public policy side.The president and many governors have set a goal to return America to a position of international leadership in educational attainment.
It's the right goal,we just need a financing strategy to get there.That doesn't mean just more money,although some more money will be needed.It also means better attention to effectiveness and to efficiency,and to making sure that spending goes to the places that will make a difference in educational attainment.We know how to do it,if we want to.

Travel Across Africa
For six hours we shot through the barren（荒芜的）landscape of the Karoo desert in
South Africa. Just rocks and sand and baking sun. Knowing our journey was ending,Daniel and I just wanted to remember all we had seen and done. He used a camera. I used words. I had already finished three notebooks and was into the fourth,a beautiful leather notebook I'd bought in a market in Mozambique.
Southern Africa was full of stories and visions.We were almost drunk on sensations,the roaring（咆哮）of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana.
And then the other things:dogs in the streets,whole families in Soweto living in one room,a kilometre from clean water.
As we drove towards the setting sun,a quietness fell over us. The road was empty一we hadn't seen another car for hours.And as I drove,something caught my eye,something moving close enough to touch them,to smell their hot breath. I didn't know how long they had been there next to us.
I shouted to Dan:“Look!”But he was in a deep sleep,his camera lying useless by his feet. They raced the car for a few seconds,then disappeared far behind us,a memory of he- roic forms in the red landscape.
When Daniel woke up an hour later I told him what had happened.
”Wild horses?”he said.”Why didn't you wake me up,Sophia?”
”I tried. But they were gone after a few seconds.”
”Are you sure you didn't dream it?”
”You were the one who was sleeping!”
”Typical”,he said.”The best photos are the ones we never take.”
We checked into a dusty hotel and slept the sleep of the dead.
Daniel and Sophia drove slowly through the busy desert.
