Scientists are trying to make the deserts into good land again. They want to bring water to the deserts， so people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is becoming desert all the time. Scientists may not be able to change the desert in time.
Why is more and more land becoming desert？ Scientists think that people make deserts. People are doing bad things to the earth.
Some places on the earth don’t get much rain. But they still don’t become deserts. This is because some green plants are growing there. Small green plants and grass are very important to dry places. Plants don’t let the sun make the earth even drier. Plants do not let the wind blow(吹) the dirt away. When a bit of rain falls， the plants hold the water. Without plants， the land can become desert more easily.
小題1: Deserts ________.
A．never have any plants or animals in them
B．can all be turned into good land before long
C．a(chǎn)re becoming smaller and smaller
D．get very little rain
小題2: Small green plants are very important to dry places because __________.
A．they don’t let the sun make the earth even drier
B．they don’t let the wind blow the soil away
C．they hold water
D．All of the above.
小題3: After reading this passage, we learn that __________.
A．plants can keep dry land from becoming desert
B．it is good to get rid of the grass in the deserts
C．a(chǎn)ll places without much rain will become deserts
D．it is better to grow crops on dry land than to cut them

The internet will open up new vistas (前景), create the global village —you can make new friends all around the world .That, at least, is what it promised us. The difficulty is that it did not take the human mind into account. The reality is that we cannot keep relationships with more than a limited number of people. No matter how hard the internet tries to put you in communication, its best efforts will be defeated human mind.
The problem is twofold（雙重的）.First, there is a limit on the number of people we can hold in mind and have a meaningful relationship with. That number is about 150 and is set by the size of our brain. Second, the quality of your relationships depends on the amount of time you invest（投入）in them. We invest a lot in a small number of people and then distribution what’s left among as many others as we can. The problem is that if we invest little time in a person, our engagement with that person will decline（減弱）until eventually it dies into “someone I once knew”.
This is not, of course, to say that the internet doesn’t serve a socially valuable function. Of course it does. But the question is not that it allows you to increase the size of your social circle to include the rest of the world, but that you can keep your relationships with your existing friends going even though you have to move to the other side of the world.
In one sense, that’s a good thing. But it also has a disadvantage. If you continue to invest in your old friends even though you can no longer see then, then certainly you aren’t using your time to make new friends where you now live. And I suspect that probably isn’ t the best use of your time. Meaningful relationships are about being able to communicate with each other, face to face. The internet will slow down the rate with which relationships end, but it won’t stop that happening eventually.
小題1:What is stressed in the first paragraph?
A．The present situation of the internet.
B．The difficulty in communication on the internet.
C．The socially valuable function of the internet.
D．The role of the human mind in the internet communication.
小題2:The underlined word “engagement” in the second paragraph probably means “      ”.
A．a(chǎn)ppointmentB．connectionC．interviewD．a(chǎn)greement
小題3: According to the passage, the author holds the view that      .
A．the internet fails to play so valuable a role in communication as it promised
B．the Internet determines the quality of social relationships
C．the internet greatly increases the size of social circles
D．the internet communication is no less effective than the face-to-face talk
小題4: What is the author’s attitude towards the use of the internet to strengthen relationships?
A．He is uncertain about it.B．He is hopeful of it
C．He approves of itD．He doubts it

The small coastal town of Broome, in northwest Australia, is a remote village in the vast countryside.
There are no traffic jams and hardly any roads. There is only the massive Australian wild land, where some houses are 500 miles apart and some driveways are 50 miles long.
There seem to be only two main sources of entertainment out here: the sunset at the beach and Sun Pictures.
Sun Pictures is a very different movie theater：The seats are park benches and deck chairs, but you’re also welcome to sit on the grass.
It is the world’s oldest outdoor movie garden. Sun Pictures was built in 1916 on the other side of the globe from Hollywood. All the big films were shipped here and the lonely country was amazed.
Broome resident Pearl Hamaguchi has never traveled far from home. But in the Sun Pictures chairs, under the deep blue night sky, she has been almost everywhere.
“And we came back excited about Gregory Peck,” she recalled.
This is one of the few places left in the world where you can see two sets of stars at the same time-----one set in the sky, the other in the film.
Each night, dozens of people from around the world line up at the old wooden stand, with no computer in sight, and buy their tickets to the latest films.
Sun Pictures is also a museum, exhibiting projectors(放映機(jī)) that date back to the silent films, a portrait gallery of the famous people who never knew about this place---- even though they came here all the time.
Every once in a while, I’m told, you might find a non-ticket holder in your seat. That’s why it’s always a good idea to shake out your chair to make sure there are no spiders or scorpions.
“We’ve only had a couple of scorpion incidents but no one’s been stung yet,” said Aaron Mestemaker, a tourist visiting from Michigan.
Sun Pictures is a holy hall of movie history and a reminder that air conditioning and carpet are no match for grass and fresh air---even when the lizards steal the scene.
小題1:. The first two paragraphs want to show that__________.
A．living in Broome is inconvenient
B．the life in Broome is boring
C．few people like to live in Broome
D．Broome is simple but vast
小題2:.Sun Pictures is different from other theaters because _________.
A．it is the most historical outdoor theater in the world
B．the audience can either sit on chairs or on the grass
C．it was built by some constructor from Hollywood
D．a(chǎn)ll the films were imported here from Hollywood
小題3:. Gregory Peck is most probably the name of_________.
A．a(chǎn) placeB．a(chǎn) filmC．a(chǎn) movie starD．a(chǎn) country fellow
小題4:. It can be inferred that the tourists in Broome are most attracted by ________.
A．its peacefulnessB．its beautiful sunset
C．the Sun PicturesD．the gallery of movie stars

Modern inventions have speeded up people’s lives amazingly. Motor-cars cover a hundred miles in little more than an hour, aircraft cross the world inside a day, while computers operate at lightning speed. Indeed, this love of speed seems never-ending. Every year motor-cars are produced which go even faster and each new computer boasts (吹噓) of saving precious seconds in handling tasks.
All this saves time, but at a price. When we lose or gain half a day in speeding across the world in an airplane, our bodies tell us so. We get the uncomfortable feeling known as jet-lag; our bodies feel that they have been left behind in another time zone. Again, spending too long at computer results in painful wrists and fingers. Mobile phones also have their dangers, according to some scientists; too much use may transmit harmful radiation into our brains, a consequence we do not like to think about.
However, what do we do with the time we have saved? Certainly not relax, or so it seems. We are so accustomed to constant activity that we find it difficult to sit and do nothing, or even just one thing at a time. Perhaps the days are long gone when we might listen quietly to a story on the radio, letting imagination take us into another world.
There was a time when some people’s lives were devoted simply to the cultivation of the land or the care of cattle. No multi-tasking there; their lives went on at a much gentler pace, and in a familiar pattern. There is much that we might envy about a way of life like this. Yet before we do so, we must think of the hard tasks our ancestors faced: they farmed with bare hands, often lived close to hunger, and had to fashion tools from wood and stone. Modern machinery has freed people from that primitive existence.
小題1: The new products become more and more time-saving because       .
A．the manufacturers boast a lotB．time is limited
C．the prices are increasingly highD．our love of speed seems never-ending
小題2: What does “the days” in Paragraph 3 refer to?
A．Simple life in the past.B．Imaginary life.
C．Times of inventions.D．Time for constant activity.
小題3:. What is the author’s attitude towards the modern technology?
A．Critical.B．Optimistic.C．Objective.D．Negative.
小題4:. What does the passage mainly discuss?
A．The present and past times.B．Modern technology and its influence.
C．Imaginations and inventions.D．Machinery and human beings.

If you've ever seen a James Bond movie，you'll know that the hero gets around in a smart Aston Martin car. Even if you know full well that you could never afford such an expensive vehicle, you don't forget the name, or the car.
　 Why? You have been affected by product placement.
　 Companies pay a film to place their products in the movie. Product placement took off in the West in the 1980s and is now catching on in China. Two Hunan Satellite TV dramas are recent examples：Ugly Wudi and Let's Go Watch the Meteor Shower (《一起去看流星雨》).
　 Shampoo, mobile phones, cars and fitness centers–anything can be product-placed. Advertisers value the mass appeal of the movies, knowing that a successful film can showcase their goods to hundreds of thousands of viewers. But when product placement takes over, artistic considerations can take a back seat.
　 Cai Zhiyong has been product-placing for years. The Beijing-based advertiser admits there is a conflict between art and business. He explains the way one ad works. In If You are the One (《非誠(chéng)勿擾》), the actress Shu Qi plays a flight attendant. The movie contains product placement for airline companies.
　 Cash-strapped filmmakers often have to give less consideration to the quality of their work because they need money from advertisers. In the original story for Meteor Shower, the heroine's mother owned an ice cream shop. But no ice cream company wanted to sponsor (贊助) the film. For this reason, the story was changed. In the film the man drinks 20 cups of milk tea instead of eating ice cream.
　 So you may see the power of business over the movies, since the script (劇本) was perhaps written so that a product could be placed-whether it was ice cream or milk tea.
小題1:James Bond movies are mentioned in the first paragraph to show_________.
A．how popular James Bond is B．how great the Aston Martin car is
C．how to make a movie more artistic D．how effectively product placement works
小題2:Product placement can have a bad effect on the_________ of a movie.
A．a(chǎn)tmosphere B．mass appeal C．box-office success D．a(chǎn)rtistic value
小題3:What does the underlined word "cash-strapped" in Paragraph 6 probably mean?
A．Short of money. B．Wasting a lot of money.
C．having enough money. D．Trying to save money.
小題4:We can learn from the example of Meteor Shower that__________.
A．business has a big say in the movie
B．the original story was not suitable for a movie
C．filmmakers are only concerned about making money
D．milk tea is more popular than ice cream

Trekking through the mists of the Huangshan mountains , I came upon a young man painting the scenery with traditional brush and ink on rice paper. He smiled proudly as he showed me his work. It was indeed quite beautiful for a painting , but it paled compared to the living scene before my eyes: mountaintops surrounded by light clouds, an endless dance of wind and fog that changes alternately in the dark hills beneath. How futile it must feel for a mere human being to try to capture that , I thought.
Yet for centuries ,these mountains in the heart of China have been a destination for artists and poets , who come to commune with nature in one of its more striking pose-and struggle to replicate its beauty. Along with the artists and poets come lovers ,who grasp locks symbolic of their undying love to the chain fences that protect hikers from the steep cliffs .Seventy miles of trials wind around 72peaks , the two majestic of which are Capital of Heaven and Lotus Flower.
In 1990 ,UNESCO declared Huangshan a Cultural and Natural Property , thereby ensuring that the area’s physical beauty will be preserved forever. Pheasant and deer abound. Hundreds of plants are said to heal the body and the famous hot springs are known for their healing qualities . An hour’s meditation in one of these pools is a great way  to end a day of hiking .
The three staging areas for Huangshan visitors are Jade Screen, the Hot Spring area and the North Sea. The Xi Hai and Bei Hai ,located on different summits are three-star hotels serving Chinese and Western food as well as wine and liquor from East and West.
Huangshan may not be exactly off the beaten path , but it is on a road well worth taking.
小題1: The writer thought the young man ‘s painting    .
A not a bit beautiful    B  not as beautiful as the living scene
C more beautiful than the living scene   D  beautiful enough to caught the nature’s beauty
小題2: Why would lovers like to grasp locks to the chain fences?
A because locks symbolize lovers’ forever love
B because locks can protect lovers from the cliffs
C because locks help lovers climb to the top quickly
D because locks contribute to enjoy nature easily
小題3: What is the purpose of the passage?
A To introduce some hotels in Huangshan mountains
B To recommend Huangshan mountains to tourists
C To speak highly of the beauty of Huangshan mountains
D To stress the convenience to climb Huangshan mountains

Just as the world’s most respected scientific bodies have confirmed that the world is getting hotter, they have also stated that there is strong evidence that humans are driving the warming. Countless recent reports from the world’s leading scientific bodies have said the same thing. For example, a 2010 summary of climate science by the Royal Society stated that: “There is strong evidence that the warming of the Earth over the last half-century has been caused largely by human activity.”
The idea that humans could change the planet’s climate may be counter-intuitive(與直覺不符的), but the basic science is well understood. Each year, human activity causes billions of tons of greenhouse gases to be released（釋放）into the atmosphere. As scientists have known for years, these gases hold heat that would otherwise escape to space, wrapping the planet in an invisible blanket.
Of course, the planet’s climate has always been changing thanks to “natural” factors(因素) such as changes in solar or volcanic（火山的）activity, or cycles relating the Earth’s going around the sun. According to the scientific literature, however, the warming recorded to date matches the pattern of warming we would expect from a build-up of greenhouse gas in the atmosphere – not the warming we would expect from other possible causes.
Even if scientists did discover another reasonable explanation for the warming observed so far, that would beg a difficult question. As Robert Henson puts it in The Rough Guide to Climate Change: “If some newly discovered factor can account for the climate change, then why aren’t carbon dioxide（二氧化碳）and the other greenhouse gases producing the warming that basic physics tells us they should be?”
The only way to prove with 100% certainty that humans are responsible for global warming would be to run an experiment with two identical Earths – one with human influence and one without. That obviously isn’t possible, and so most scientists are careful not to state human influence as an absolute certainty.
小題1: In most scientists’ opinion, the global warming is mainly caused by ________.
A．solar activity
B．volcanic activity
C．the Earth’s going around the sun
D．human activity
小題2:The text is developed by ________.
A．giving typical examples
B．following the order of space
C．a(chǎn)nalyzing a theory and arguing it
D．comparing and finding differences
小題3:The underline word “identical” means ________.
A．totally different
B．exactly the same
C．extremely important
D．relatively independent
小題4: Which of the following can be the best title?
A．Are All the Scientists Really Scientific?
B．Where Is Global Warming Leading Us to?
C．Are Humans Definitely Causing Global Warming?
D．What’s Relation of Global Warming and Greenhouse Gases?
