If California were not already so famous for Sillicon Valley(硅谷) and Hollywood, it might be well－known for the groups of water－technology firms in its San Diego County. The reverse－osmosis (RO) spiral module, the technique that supports turning seawater and waste－water into drinkable stuff, began in San Diego in 1964. Today dozens of firms in the area supply many of the world's approximately 13，000 RO plants in places from the Persian Gulf and Israel to Australia and China.
Southern California itself, however, has not so far been a big user of its own technology. This is surprising, given that the whole American south－west faces a water problem. But now as the climate gets warmer and the population increases, there is more agreement that the existing infrastructure, consisting of vast pipes that carry water from the Sacramento Delta in the north and the Colorado River in the east, will not be enough. In places such as San Diego, which has inadequate and salty groundwater and currently imports 90% or its water, the answers must be greater conservation, reusing as much water as possible, and getting most of the rest from the sea.
The first part, conservation, has been widely accepted by the public. San Diego today uses less water with a larger population than it did in 1989, the year water consumption peaked. The second part, water recycling has been a hard sell, because of an unpleasant factor. Americans still use the term “toilet－to－tap” for recycling, even though properly treated waste－water is nowadays completely clean. Singapore made its programme acceptable in part by renaming it as NEWater.
This is where desalination comes in, which means taking the salt out of salt water. A firm called Poseidon Resources is now close to building the biggest desalination plant in America behind a power station by the beach in Carlsbad. The power plant sucks in 304m gallons of seawater a day for cooling, so Poseidon plans to change 104m gallons a day by using the RO spiral module.
Lots of people like the idea. Once fully running in 2015, the plant could produce 10% of the region's water. And there are plans for more desalination plants. Many places would need to take much less water from the endangered Colorado River. But a few people hate it a lot. Joe Geever, an expert in biology, says desalination uses too much energy and that Poseidon plant would kill too much sea life. He understands that there is a role for desalination, he says, but would rather not have it right there, right now, and on this scale.Which of the following is WRONG about the RO spiral module according to the passage?

It was a Sunday and the heavy storm had lasted all night. The morning after the storm, though, was beautiful: blue skies, warm air and a calm, inviting sea touching the shore gently.
My father realized it was a good day for fishing and invited my sister and me to go with him. I was only 14 and fishing had never been my thing, but I decided to go all the same. I’ m so glad I did.
On the way to the harbor we could see the terrible destruction on the coast, but the harbour itself was in fairly good shape．After all, it was protected by the arms of a bay that had only one tiny channel to the sea. As we got on board, we noticed two big humps(脊背) in the distance.
On approaching them, we saw it was a mother whale with her baby. We couldn’t believe it — there weren’t any whales along the coast here. The storm must have driven them across the ocean into the bay, in which the still water was so badly polluted that nothing could survive.
The little baby whale—actually as big as our boat—was obviously stuck and could not move. The mother dived under the water and came up suddenly, making big whirlpools（漩涡） and waves. "She’s trying to help her baby, but on the wrong side," my father said. At this point, my father moved our boat in a semicircle to the other side and, heading the boat towards the baby whale, pushed it gently. With our several gentle pushes the big hump turned over and disappeared under water. Then it swam up right beside its mum. They struggled in their desperate attempts to escape but missed the exit and started heading in the wrong direction. We hurried up to the whales and tried to lead them towards the bay channel. Slowly, they let us lead them, sometimes rising from the water right beside us to breathe—and to give us a trusting look with those huge eyes. Once they hit their first part of clean water flowing straight from the sea, the mum gave us a wave with her tail and off. They swam into the distance.
In the excitement it had felt like only a few minutes, but we had been with those wonderful animals for almost an hour and a half. That was the simple and lasting beauty of the day. Nearly four decades later, I still look back fondly to that golden day at sea. In Para2 the author says "I’ m so glad I did." because _________.

What is the theme of the story?
| A．Saving lives brings people a sense of happiness. |
| B．Fishing provides excitement for children. |
| C．It’s necessary to live in harmony with animals. |
| D．It’s vital to protect the whale in the ocean. |

I walked alongside my father, clutching his right hand．All my clothes were new: the black shoes, the green school uniform, and the red cap．They did not make me happy, however, as tins was the day I was to be thrown into school for the first time．I tried in vain lo convince him that I did nothing wrong all the way, but it didn’t help．
When we．arrived at the sate we could see the courtyard, vast and full of boys and girls．I hesitated and clung to his hand, but he gently pushed me from him．"Be a man, "he said．"today you truly begin your life．You will find me waiting for you when it’s time to leave．"
I took a few steps．Then the faces of the boys and girls came into view．I did not know a single one of them, and none of them knew me．I felt I was a stranger who had lost his way．But then some boys began to glance at me in curiosity, and one of them came over and asked, " Who brought you? "
"My father," I whispered．
’’My father’s dead, " he said simply．
I did not know what to say．The gate was now closed．Some of the children burst into tears．The bell rang．A lady came along, followed by a group of men．The men began soiling us into ranks．We were formed into an intricate pattern in the great courtyard surrounded by high buildings．
Well, it seemed that my misgivings had had no basis．From the first moments I made many friends and fell in love with many girls．I had never imagined school would have this rich variety of experiences．
We played all sorts, of games．In the music room we sang our first songs．We also had our first introduction to language．We saw a globe of Earth, which revolved and showed the various continents and countries．We started lean-line numbers, and we were told the story of the Creator of the universe．We ate delicious food, took a little nap, and woke up to go on with friendship and love, playing and learning．
Our path, however, was not totally sweet and unclouded．We had to be observant and patient．It was not all a matter of playing and fooling around． Rivalries could bring about pain and hatred or give rise to fighting．And while the lady would sometimes smile, she would often yell and scold．Even more frequently
she would resort to physical punishment．
The bell rang, announcing the passing of the day and the end of work．The children rushed toward the gate, which was opened again．I said goodbye to friends and sweethearts and passed through the gate．I looked around but found no trace of my father, who had promised to be there．I stepped aside to wait.The writer hesitated and clung to his father’s hand when they got to the school gate because ____．

“Everybody loves a bargain.” Is a well-known saying. One person’s useless, ugly, or broken object can be another person’s bargain. That is why so many Americans do not throw things away. They put them outside their house. They put on a "For Sale" sign. And, as simple as that, they have a yard sale.
The sellers put a paid announcement in a local newspaper. It tells when and where the yard sale will take place. These sales are very popular during weekends in spring, summer, and autumn.
Early in the morning, all the things to be sold are carried out of the house. Then they sit all day in the sunlight -- like tired guests at a party -- waiting for someone to take them home.
Just about anything can be sold at a yard sale. Sometimes, there are more clothes than anything else. Cooking equipment is also popular. So are old toys, tools, books, tables, and chairs. Then there are objects called "white elephants." A white elephant is something you think is extremely ugly or useless. It may be an electric light shaped like a fish. You feel a sharp pain whenever you look at it. To someone else, however, it might be a thing of beauty and joy.
Some people go to yard sales to find a special thing that they collect. It may be old toy trains, for example, or paintings of dogs. Experts say more Americans are collecting old things now than ever before. Most people who go to yard sales, however, are not looking for anything special. They might buy an object simply because it costs so little. They enjoy negotiating over prices, even if they really do not need the object. Later, they may hold their own yard sale to sell all the things they have bought.What kind of things will go to a yard sale?
| A．Cheap and ugly things． | B．Things people no longer use． |
| C．Things out of season． | D．Things of great value． |

| D．most people who go to yard sales want to make money |
If your cellphone suddenly stops working, don’t blame the service provider．The malfunction（故障） might well have been caused by something bigger -- a solar storm．Experts expect that Earth will see more solar activity in the near future．The malfunction of electronic devices will just one of the effects．
Sunspots（太阳黑子） serve as an indicator of the sun’s activity．For the past two years, sunspots have mostly been missing．Their absence, the most prolonged in nearly 100 years, has taken even seasoned sun watchers by surprise．
When the number of sunspots drops at the end of each 11-year cycle, solar storms die down and all become much calmer. This “solar minimum” doesn’t last long. Within a year, sunspots and solar storms begin to build toward a new crescendo, the next solar maximum.
What’s special about this latest cycle is that the sun is having trouble starting the next solar cycle. The sun began to calm down in late 2007, so no one expected many sunspots in 2008. They should return in 2010. Scientists have predicted that the next solar cycle could be the most active on record: more sunspots and more solar storms. However, sunspots are mostly missing now.
Since the earth is in close contact with the sun, strong solar activities can bring trouble to our life. People of the 21st century rely on high-tech systems for the basics of daily life. Air travel and radio communications can be affected by strong solar activities. A big solar storm could cause 20 times more economic damage than Hurricane Katrina.
What the sun will do next is beyond our ability to predict. Most astronomers think that the solar cycle will go on but at low level. However, there is also evidence that the sun is losing its ability to produce sunspots. By 2015, they could be gone altogether.The sun watcher feel surprised at .
| A．the longest sunspots’ absence | B．the largest sunspot number |
| C．the malfunction of electronic devices | D．the serious damage by sunspots |
What does the underlined word “crescendo” in paragraph 3 most probably mean?
| A．small number | B．high level |
| C．usual cycle | D．fresh start |
We can infer that in the past two years .
| A．solar activities have brought much trouble to our life |
| B．the number of sunspots has increased to a large extent |
| C．the solar minimum took the place of the solar maximum |
| D．our cellphones have seldom been interrupted by the solar storm |
Which statement does the text lead you to believe?
| A．Solar activities do no harm to our daily life. |
| B．Hurricane Katrina is also a type of solar storms. |
| C．It’s difficult to predict sunspots. |
| D．From now on there’ re no sunspots. |
