Most of what I really need to know about how to live and what to do and how to be,I learned in kindergarten.Wisdom was not at the top of the graduate mountain,but there in the sand pile at nursery school.
These are the things I learned:Share everything. Play fair. Don't hit people.Put things back where you found them.Clean up your own mess.Don't take things that aren't yours.Say you're sorry when you hurt somebody.Wash your hands before you eat.Warm cookies and cold milk are good for you.Live a balanced life.Learn some and think some and draw and paint and sing and dance and play and work everyday some.
Take a nap every afternoon.When you go out into the world,watch for traffic,hold hands and stick together. Be aware of wonder. Remember the little seed in the plastic cup?The roots go down and the plant goes up and nobody really knows how or why,but we are all like that.
Goldfish and hamsters and white mice and even the little seed in the plastic cup一they all die.So do we.
And then remember the book about Dick and Jane and the first word you learned,the biggest word of all: Look.Everything you need to know is in there somewhere,the Golden Rule and love and basic sanitation,ecology and polities and sane living.
Think of what a better world it would be if we all一the whole world一had cookies and milk about 3 o'clock every afternoon and then lay down with our blankets for a nap.Or if we had a basic policy in our nations to always put things back where we found them and cleaned up our own messes.And it is still true,no matter how old you are,when you go out into the world,it is better to hold hands and stick together.
When you go out into the world,watch for traffic,hold hands and stick together.

Better Solar Energy Systems:More Heat,More Light
Solar photovoltaic(光电的)thermal energy systems , or PVTs , generate both heat and electricity , but
_________ (51)now they haven't been very good at the heat-generating part compared to a stand-alone
solar thermal collector. That ' s because they operate at low temperatures to cool crystalline silicon(晶体硅)
solar cells, _______(52)lets the silicon generate more electricity but isn't a very efficient way to gather
heat.
That's a problem of economics.Good solar hot-water systems can harvest much more energy than a
solar一electric system at a substantially lower _________(53).And it's also a space problem:photovoltaic
cells can
_________(54)up all the space on the roof,leaving little room for thermal applications.
In a pair of studies,Joshua Pearce,an associate professor of materials science and engineering,has de-
vised a_________(55)in the form of a better PVT made with a different kind of silicon.
Most solar panels are made with crystalline silicon,but you can also make solar cells out of amorphous
(非晶形的)silicon , commonly known
________( 56 ) thin-film silicon. They don ' t create as much elec-
tricity,but they are lighter,flexible,and cheaper. And,because they________(57)much less silicon,they
have a greener footprint._________(58),thin-film silicon solar cells are vulnerable to some bad一news
physics in the form of the Staebler-Wronski effect.
"That means that their efficiency drops when you_________(59)them to light一pretty much the worst
possible effect for a solar cell,"Pearce explains,which is one of the__________(60)thin-film solar panels
make up only a small fraction of the market.
However,Pearce and his team found a_______(61)to engineer around the Staebler-Wronski effect by
incorporating thin-film silicon in a new________(62)of PVT. You don't have to cool down thin-film sili-
con to make it work.In fact,Pearce's group discovered that by heating it to solar-thermal operating tempera-
tures,near the boiling_________(63)of water,they could make thicker cells that largely_________(64)
the Staebler-Wronski effect.When they applied the thin-film silicon directly to a solar thermal energy collector,
they also found that by baking the cell once a day,they_________(65)the solar cell's electrical efficiency
by over 10 percent.

Animal's “Sixth Sense”
A tsunami(海啸)was triggered(引发)by an earthquake in the Indian Ocean in December, 2004.It killed tens of thousands of people in Asia and East Africa. Wild animals,1, seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a“sixth sense” for2 ,experts said.
Sri Lankan wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island's coast clearly 3 wild beasts,with no dead animals found.
“No elephants are dead,not4a dead rabbit. I think animals can5 disaster.
They have a sixth sense. They know when things are happening,”H.D. Ratnayake,deputy director of Sri Lanka's Wildlife Department,said about one month after the tsunami attack. The6washed floodwaters up to 2 miles inland at Yala National Park in the ravaged(被 毁坏的)southeast, Sri Lanka's biggest wildlife7and home to hundreds of wild elephants and several leopards(豹).
“There has been a lot of8 evidence about dogs barking or birds migrating before volcanic eruptions(火山爆发)or earthquakes. But it has not been proven ,” said Matthew van Lierop,an animal behavior 9 at Johannesburg Zoo.
“There have been no10studies because you can't really test it in a lab or field setting , ” he told Reuters. Other authorities concurred(同意)with this11.
“Wildlife seem to be able to pick up certain12 ,especially birds…there are many re- ports of birds detecting impending(迫近的)disasters , ” said Clive Walker , who has written several books on African wildlife.
Animals13 rely on the known senses such as smell or hearing to avoid danger such as predators(食肉动物).
The notion of an animal “sixth sense”一or14other mythical power一is an enduring one which the evidence on Sri Lanka's ravaged coast is likely to add15.

The iPad
1 The iPad is a tablet computer(平板电脑)designed and developed by Apple. It is par-ticularly marketed as a platform for audio and visual media such as books,periodicals(期刊),movies,music,and games,as well as web content. At about 1 .5 pounds(680 grams), its size and weight are between those of most contemporary smartphones and laptop comput-ers.Apple released the iPad in April 2010,and sold 3 million of the devices in 80 days.
2 The iPad runs the same operating system as iPod Touch and iPhone. It can run its own applications as well as ones developed for iPhone. Without modification,it will only run pro-grams approved by Apple and distributed via its online store.
3 Like iPhone and iPod Touch,the iPad is controlled by a multitouch display一a break from most previous tablet computers, which uses a pressure-triggered stylus(触控笔).The iPad uses a Wi-Fi data connection to browse(浏览)the Internet, load and stream media, and install software. Some models also have a 3G wireless data connection which can connect to GSM 3G data networks. The devices is managed and synchronized(同步)by iTunes on a per-sonal computer via USB cable.
4 An iPad has different features and applications one can use to execute different and in-teresting things. There are lots of iPad applications that the owner can use to enhance the way they communicate. Some of these are how to use social networking sites and other online options.One of the most common uses is for e-mail services. iPad applications like Markdown Mail allow the adoption of specific and particular options. They enable the owner to personal-ize their email accounts.
5 While the iPad is mostly used by consumers it also has been taken up by business us-ers. Some companies are adopting iPads in their business offices by distributing or making available iPads to employees.Examples of uses in the workplace include lawyers responding to clients,medical professionals accessing health records during patient exams,and manag-ers approving employee requests.A survey by Frost Sullivan shows that iPad usage in work-places is linked to the goals of increased employees productivity,reduced paperwork,and in-creased revenue.

The Value of Motherhood
In shopping malls,the assistants try to push you into buying“a gift to thank her for her unselfish love”.When you log onto a website,a small popo-up invites you to book a bouquet for her. Commercial warmth and gratitude are the atmosphere being spread around for this special Sunday in May.
______(1)The popularity of Mother's Day around the world suggests that Jarvis got all she wanted. In fact,she got more一enough to make her horrified.
______(2)They buy,among other things,132 million cards. Mother's Day is the No. 1 holiday for flower purchases.Then there are the various commodities,ranging from jewelry and clothes to cosmetics and washing powder,that take advantage of the promotion opportu- nities.Because of this,Jarvis spent the last 40 years of her life trying to stop Mother's Day. One protest against the commercialization of Mother's Day even got her arrested一for distur- bing the peace,interestingly.
______(3)As Ralph Fevre,a reporter at the UK newspaper The Guardian,observe, traditionally“motherhood is something that we do because we think it's right.”But in the logic of commercialism,people need something in exchange for their time and energy. A ca- reer serves this purpose better.
______(4)So they work hard and play hard. Becoming a mother,however,inevitably handicaps career anticipation.
______(5)According to The Guardian,there are twice as many child-free young women as there were a generation ago. Or,they put off the responsibility of parenting until later in their lives.
So,Fevre writes that the meaning of celebrating Mother's Day needs to be updated:“It is to persuade people that parenting is a good idea and to honor people for their attempt to be good people.”
______(5)
A: The American version of Mother's Day was thought up as early as 1905,by Anna Jarvis,as a way of recognizing the real value of motherhood.
B: But what's more,commercialism changes young people's attitude towards mother-hood.
C: Obviously,the best gift will be a phone call or a visit.
D: According to a research by the US card company Hallmark,96 percent of American consumers celebrate the holiday.
E: As a result,motherhood has suffered a huge drop in status since the 1950s.
F: In addition,women are being encouraged to pursue any career they desire.

The Weight Experiment
Nicola Walters has been taking part in experiments in Scotland to discover why humans gain and lose weight. Being locked in a small room called a“ calorimeter”(热量测量室)is one way to find out.
1 .The signs above the two rooms read simply“Chamber One”and“Chamber Two”.These are the calorimeters:4m by 2m white-walled rooms where human volunteers are locked up in the name of science .Outside these rooms another sign reads“Please do not enter work in progress” and in front of the rooms advanced machinery registers every move the volunteers make.Each day,meals measured to the last gram are passed through a hole in the wall of the calorimeter to the resident volunteer.
2 .Nicola Walters is one of twenty volunteers who,over the past eight months,have spent varying periods inside the calorimeter. Tall and slim,Nicola does not have a weight problem,but thought the strict diet might help with her training and fitness programme.As a self-employed community dance rorker,she was able to fit the experiment in around her work.She saw an advert for volun- teers at her local gym and as she is interested in the whole area of diet and exercise,she thought she would help out.
3. The experiment on Nicola involved her spending one day on a fixed diet at home and the next in the room.This sequence was repeated four times over six weeks.She arrived at the calorimeter at8:30 am on each of the four mornings and from then on everything she ate or drank was carefull) measured .Her every move was noted too,her daily exercise routine,timed to the last second. At regular intervals,after eating,she filled in forms about how hungry she felt and samples were taken for analysis.
4 .The scientists help volunteers impose a kind of order on the long days they face in the room. “The first time,I only took one video and a book,but it was OK because I watched TV the rest of the time,”says Nicola. And twice a day she used the exercise bike. She pedaled(踩踏板) for half an hour,watched by researchers to make sure she didn't go too fast.
5 .It seems that some foods encourage you to eat more,while others satisfy you quickly.Volunteers are already showing that high-fat diets are less likely to make you feel full.Believing that they may now know what encourages people to overeat,the researchers are about to start testing a high-protein weight-loss diet. Volunteers are required and Nicola has signed up for further sessions.
Volunteers have to get prepared for the time in the calorimeter_________.
A: the volunteers do
B:.because she does not have a weight problem
C: because the life there can be very boring
D: make people overeat
E: because she was her own boss
F: after passing a high-protein test

The Cold Places
The Arctic is a polar region.It surrounds the North Pole.
Like Antarctica,the Arctic is a land of ice and snow.Antarctica holds the record for a low temperature reading-125 degrees
Fahrenheit below zero. Reading of 85 degrees below zero is common in both the Arctic and Antarctica.Winter temperatures average 30 degrees below zero in the Arctic .At the South Pole the winter average is about 73 degrees below zero.
One thing alone makes it almost impossible for men to live in Antarctica and in parts of the Arctic .This one thing is the low temperature-the killing chill of far North and the polar South.
To survive,men must wear the warmest possible clothing. They must build windproof shelters .They must keep heaters going at all times.Not ever for a moment can they be unprotected against the below-zero temperatures.
Men have a way of providing for themselves.Polar explorers wrap themselves in warm coats and furs .The cold makes life difficult. But the explorers can stay alive.
What about animals?Can they survive?Do we find plants?Do we find life in the Arctic and in Antarctica?Yes,we do. There is life in the oceans.There is life on land.
Antarctica,as we have seen,is a cold place indeed.But this has not always been the case.
Expedition scientists have discovered that Antarctica has not always been a frozen continent. At one time the weather in Antarctica may have much like our own.
Explorers have discovered coal in Antarctica. This leads them to believe that Antarctica at one time was a land of swamps and forests.Heat and moisture must have kept the trees in the forests alive.
Despite the hostile environment,both animals and plants can be found in the oceans and on land in polar areas.
A: Right
B: Wrong
C: Not mentioned
