A new satellite is travelling 1.5 million kilometers over a 110-day period to enter an orbit of the sun. It is called DSCOVR--the Deep Space Climate Observatory. It will replace a satellite that has been observing space weather.
DSCOVR will begin its work during the worst of the 11-year-long solar cycle. This is a time when extreme weather on the sun can have the greatest effect on planet Earth.
DSCOVR will gather information about a continuing flow of particles from the sun. We are protected from these particles by the Earth's magnetic field and atmosphere. But we are not fully protected from what scientists call Coronal Mass Ejections. These are strong storms that can happen on the sun's surface.
Thomas Berger is the director of the Space Weather Prediction Center at the National Oceanic and Atmospheric Administration, or NOAA. He says these ejections are much more dangerous than solar particles. He says the Coronal Mass Ejections are extremely large magnetic clouds that are expelled from the sun at extremely high speeds. He says when they impact Earth, it is like a hurricane impacting Earth in terms of space weather.
Violent space weather can make electric systems stop working. It can block satellite signals to Earth. It can interfere with radio signals and air travel.
Mr. Berger says we cannot stop the ejections from affecting us, but we can prepare for them if we know when they will happen. When the DSCOVR satellite records an ejection, it will release a warning. Mr. Berger says the warning will provide NOAA about 15 to 60 minutes to let people know that a very strong storm is coming in to the Earth. He says that is enough time for power grid operators to take protective action. He says it is also enough time for workers to place satellites on a safe operating method if necessary.
Mr. Berger says scientists would like even more time, of course. He says researchers are developing instruments that will give an earlier warning.
The warnings from DSCOVR will be for the whole planet. But Mr. Berger says a new system may be able to give more-targeted warnings. He says future models will be able to tell exactly what part of the world will be more at risk from a solar storm.
That means that, for the first time, humans will get both a warning that a magnetic storm is heading towards Earth and information about where it is likely to hit.The new satellite is used to ________?

One thing the tour books don’t tell you about London is that 2,000 of its residents are foxes. They ran away from the city about centuries ago after developers and pollution moved in. But now that the environment is cleaner, the foxes have come home, one of the many wild animals that have moved into urban areas around the world.
“The number and variety of wild animals in urban areas is increasing,” says Gomer Jones, president of the National Institute for Urban Wildlife, in Columbia, Maryland. A survey of the wildlife in New York’s Central Park last year tallied the species of mammals, including muskrats, shrews and flying squirrels. A similar survey conducted in the 1890s counted only five species. One of the country’s largest populations of raccoons (浣熊) now lives in Washington D.C., and moose (驼鹿) are regularly seen wandering into Maine towns. Peregrine falcons(游隼) dive from the window ledges of buildings in the largest U.S. cities to prey on (捕食) pigeons.
Several changes have brought wild animals to the cities. Foremost is that air and water quality in many cities has improved as a result of the 1970s pollution-control efforts. Meanwhile, rural areas have been built up, leaving many animals on the edges of suburbs. In addition, urban wildlife refuges (避难处)have been created. The Greater London Council last year spent￡750,000 to buy land and build 10 permanent wildlife refuges in the city. Over 1,000 volunteers have donated money and cleared rubble from derelict lots. One evening last year a fox was seen on Westminster Bridge looking up at Big Ben.
For peregrine falcons, cities are actually safer than rural cliff dwellings (悬崖栖息地). By 1970 the birds had died out east of the Mississippi because the DDT had made their eggs too thin to support life. That year, scientist Tom Cade of Cornell University began raising the birds for release in cities, for cities afforded abundant food.
Cities can attract wild animals without turning them harmful. The trick is to create habitats where they can be self-sufficient but still be seen and appreciated. Such habitats can even be functional. In San Francisco, the local government is testing different kinds of rainwater control basins to see not only which ones retain (保持) the cleanest water but which will attract the most birds.The first paragraph suggests that ________.
| A．environment is crucial for wildlife |
| B．tour books are not always a reliable source of information |
| C．London is a city of fox |
| D．foxes are highly adaptable to environment |
Which of the following is NOT a reason that wildlife is returning to the cities?
| A．Food is plentiful in the cities. |
| B．Wildlife is appreciated in the cities. |
| C．Wildlife refuges have been built in the cities |
| D．Air and water quality has improved in the cities |
The underlined word “tallied” in Para. 2 means __________.
| A．distinguished | B．described | C．counted | D．excluded |
It can be inferred from the passage that _________.
| A．Londoners are putting more and more wild animals into their zoos. |
| B．Londoners are happy to see wild animals return to their city |
| C．Londoners are trying to move wild animals back to the countryside |
| D．Londoners have welcomed the wild birds, but found foxes a problem |
What is the passage mainly about?
| A．Wildlife returning to large cities |
| B．Foxes returning to London |
| C．Wild animals living in zoos |
| D．A survey of wildlife in New York |
About this time every year, I get very nostalgic(怀旧的). Walking through my neighborhood on a fall afternoon reminds me of a time not too long ago when sounds of children filled the air, children playing games on a hill, and throwing leaves around in the street below. I was one of those children, carefree and happy. I live on a street that is only one block long. I have lived on the same street for sixteen years. I love my street. One side has six houses on it, and the other has only two houses, with a small hill in the middle and a huge cottonwood tree on one end. When I think of home, I think of my street. Only I see it as it was before. Unfortunately things change. One day, not long ago, I looked around and saw how different everything has become. Life on my street will never be the same because neighbors are quickly grown old, friends are growing up and leaving, and the city is planning to destroy my precious hill and sell the property to contractors.
It is hard for me to accept that many of my wonderful neighbors are growing old and won’t be around much longer. I have fond memories of the couple across the street, who sat together on their porch swing almost every evening, the widow next door who yelled at my brother and me for being too loud, and the crazy old man in a black suit who drove an old car. In contrast to those people, the people I see today are very old neighbors who have seen better days. The man in the black suit says he wants to die, and another neighbor just sold his house and moved into a nursing home. The lady who used to yell at us is too tired to bother any more, and the couple across the street rarely go out to their front porch these days. It is difficult to watch these precious people as they near the end of their lives because at once I thought they would live forever.
The “comings and goings” of the younger generation of my street are now mostly “goings” as friends and peers move on. Once upon a time, my life and the lives of my peers revolved around home. The boundary of our world was the gutter at the end of the street. We got pleasure from playing night games or from a breathtaking ride on a tricycle. Things are different now, as my friends become adults and move on. Children who rode tricycles now drive cars. The kids who once played with me now have new interests and values as they go their separate ways. Some have gone away to college like me, a few got married, two went into the army, and one went to prison. Watching all these people grow up and go away makes me long for the good old days.
Perhaps the biggest change on my street is the fact that the city is going to turn my precious hill into several lots for now homes. For sixteen years, the view out of my kitchen window has been a view of that hill. The hill was a fundamental part of my childhood life; it was the hub of social activity for the children of my street. We spent hours there building forts, sledding, and playing tag. The view out of my kitchen window now is very different; it is one of tractors and dump trucks tearing up the hill. When the hill goes, the neighborhood will not be the same. It is a piece of my childhood. It is a visual reminder of being a kid. Without the hill, my street will be just another pea in the pod.
There was a time when my street was my world, and I thought my world would never change. But something happened. People grow up, and people grow old. Places changes, and with the change comes the heartache of knowing I can never go back to the times I loved. In a year or so, I will be gone just like many of my neighbors. I will always look back to my years as a child, but the place I remember will not be the silent street whose peace is interrupted by the sounds of construction. It will be the happy, noisy, somewhat strange, but wonderful street I knew as a child.The writer calls up the memory of the street _____________.

| A．continue to consider home to be the center of their lives |
| B．leave the neighborhood they grew up in |
| C．still enjoy playing card games in the evenings |
| D．develop new interests and have new dreams |

| B．the building of new homes behind his kitchen window |
| C．the fact that there are much fewer people around than in the past |

| A．his street will be very noisy and dirty |
| B．his street will soon be crowded with people |
| C．his street will have some new attractions |

My father had always been an alert observer of human character. Within seconds of meeting someone, he could sum up their strengths and weaknesses. It was always a challenge to see if any of my boyfriends could pass Dad’s test. None did. Dad was always right---they didn’t pass my test either. After Dad died, I wondered how I’d figure it out on my own.
That’s when Jack arrived on the scene. He was different from any other guy I’d dated. He could sit for hours on the piano bench with my mother, discussing some composers. My brother Rick loudly announced that Jack wasn’t a turkey like the other guys I’d brought home. Jack passed my family’s test. But what about Dad’s?
Then came my mother’s birthday. The day he was supposed to drive, I got a call. “Don’t worry,” he said, “but I’ve been in an accident. I’m fine, but I need you to pick me up.”
When I got there, we rushed to a flower shop for something for Mom. “How about gardenias?” Jack said, pointing at a beautiful white corsage(胸花). The florist put the corsage in a box.
The entire ride, Jack was unusually quiet. “Are you all right?” I asked. “I’ve been doing a lot of thinking,” he said. “I might be moving.” Moving? Then he added, “Moving in with you.” I nearly put the car on the sidewalk. “What?” I asked. “I think we should get married,” he said. He told me he’d planned his proposal in a fancy restaurant, but after the accident, he decided to do it right away. “Yes,” I whispered. We both sat dumbfounded, tears running down our cheeks. I’d never known such a tender moment. If only Dad were here to give his final approval.
“Oh, let’s just go inside.” Jack laughed. My mother opened the door. “Happy Birthday!” we shouted. Jack handed the box to her. She opened it up. Suddenly, her eyes were filled with tears. “Mom, what’s wrong?” I asked. “I’m sorry,” she said, wiping her eyes. “This is only the second gardenia corsage I’ve ever received. I was given one years ago, long before you kids were born.” “From who?” I asked. “Your father,” Mom said. “He gave me one right before we were engaged.” My eyes locked on Jack’s as I blinked away(眨掉) tears. Dad’s test? I knew Jack had passed.According to the text, we know the writer’s father was __________.

Parents are a child’s first teachers. But some parents never learned from good examples. In New York City, a nonprofit agency called Covenant House tries to help homeless young mothers become good parents.
The twelve or so teenagers who live at the shelter attend parenting classes four days a week. The class is called Mommy and Me. Teacher Delores Clemens is a mother of five and a grandmother. She teaches basic skills, like how to give a baby a bath and how to dress a baby depending on the season.
She remembers one student who learned from her mother not to pick up a crying baby. The mother said that would only make the child needy and overly demanding. Delores Clemens says, “that's not true. You have to hold your baby! He is crying for a reason. If you never pick him up, he's going to keep crying. Pick your baby up. Cuddle your baby. Hug him! And she started to do that. They just want a little cuddling and a little love. And it works!”
Delores Clemens says her students also learn how to be good mothers by letting themselves be mothered. Around three hundred fifty teenage mothers graduate from Covenant House's Mommy and Me class every year.
In class, with her baby son is Natasha. She lived on the streets. She is glad not only for the warmth and shelter of Covenant House. As she told reporter Adam Phillips, she is also glad for the help they offer in seeking a more secure life.
The World Health Organization says the United States has forty-one births for every one thousand girls age fifteen to nineteen. That is higher than other developed countries, as well as some developing ones. By comparison, northern neighbor Canada has fourteen births and southern neighbor Mexico has eighty-two.What is the text mainly about?
