Jewelweeds are pretty flowers that grow in wet, shady spots all over the Northern Hemisphere. According to a recent experiment, they seem to know their own flower family —or at least, recognize whether or not they came from the same mother plant. Together with other through their leaves, but through their roots.
Scientists planted jewelweeds in pots with either siblings（兄弟姐妹）or strangers. Sibling plants were grown from seeds that came from the same mother plant. Stranger plants were grown from seeds from different plants.
When jewelweeds were planted in pots with strangers, the plants started to grow more leaves than if they had been planted alone. This response suggests that plants are competing with strangers for sunlight, since a plant with more leaves can receive more light and make more food.
When jewelweed seedlings were planted with siblings, they few a few more branches than they normally would if they were alone—but they did not start growing lots of extra leaves. This behavior suggests the plants are more likely to share resources, rather than compete.
The plants only responded this way when they shared soil. If stranger seedlings were planted in different pots and placed next to each other, for example, they did not grow more leaves. This different shows that the plants must use their roots to detect sibling plants in the same soil. In 2007, Dudley and her team studied the Great Lakes sea rocket, a plant that grows on the beach—where it may be hard to get fresh water. In that experiment, the botanists observed that when sea rockets were planed with siblings, they tolerated each other. But when they were planted with strangers, the sea prickets reacted by working extra hard to grow lots of roots, but not extra leaves.
The different types of plants may react in different ways, but they have one thing in common: the roots. In both experiments, on Jewelweeds and sea rockets, the key was the shared soil—and other plant species may turn out to show similar behavior. These experiments, as well as earlier experiments, suggest “The phenomenon is quite common.” Says Hans de Kroonof, an ecologist in the Netherlands.

From good reading we can derive pleasure, companionship, experience, and instruction. A good book may absorb our attention so completely that for the time being we forget our surroundings and even our identity. Reading good books is one of the greatest pleasures in life. It increases our contentment when we are cheerful, and lessens our troubles when we are sad. Whatever may be our main purpose in reading, our contact with good books should never fail to give us enjoyment and satisfaction.
With a good book in our hands we need never be lonely. Whether the characters portrayed are taken from real life or are purely imaginary, they may become our companions and friends. In the pages of books we can walk with the wise and the good of all lands and all times. The people we meet in books may delight us either because they resemble human friends whom we hold dear or because they present unfamiliar types whom we are glad to welcome as new acquaintances. Our human friends sometimes may bore us, but the friends we make in books need never weary us with their company. By turning the page we can dismiss them without any fear of hurting their feelings. When human friends desert us, good books are always ready to give us friendship, sympathy, and encouragement.
One of the most valuable gifts bestowed by books is experience. Few of us can travel far from home or have a wide range of experiences, but all of us can lead varied lives through the pages of books. Whether we wish to escape from the seemingly dull realities of everyday life or whether we long to visit some far-off place, a book will help us when nothing else can. To travel by book we need no bank account to pay our way; no airship or ocean liner or stream-lined train to transport us; no passport to enter the land of our heart’s desire. Through books we may get the thrill of hazardous adventure without danger. We can climb lofty mountains, brave the perils of an Antarctic winter, or cross the scorching sands of the desert, all without hardship. In books we may visit the studios of Hollywood; we may mingle with the gay throngs of the Paris boulevards; we may join the picturesque peasants in an Alpine village or the kindly natives on a South Sea island. Indeed, through books the whole world is ours for the asking. The possibilities of our literary experiences are almost unlimited. The beauties of nature, the enjoyment of music, the treasures of art, the triumphs of architecture, the marvels of engineering, are all open to the wonder and enjoyment of those who read.
53．Why is it that we sometimes forget our surroundings and even our identity while reading?
A．No one has come to disturb us.
B．Everything is so quiet and calm around us.
C．The book we are reading is so interesting and attractive.
D．Our book is so boring that we are to finish it at a fast speed.
54．How would you account for the fact that people like their friends in books even more?
A．They are like human friends exactly. B．They are unfamiliar types we like.
C．They never desert us. D．They are purely imaginary.
55．Which of the following is true according to the text?
A．Your wish to visit some far-off place can be realized thought the pages of the books.
B．To escape from the dull realities of everyday life you should take up reading.
C．Books can always help you live a colourful life.
D．You may obtain valuable experience from reading good books.
56．By saying “…the whole world is ours for the asking,” the author implies that___________.
A．in books the world is more accessible to us
B．we can ask to go anywhere in the world
C．we can possess everything in this world
D．we can make a round-the-world trip free of charge

I have found that the way I treat insects acts as a reflection of my approach to kindness. Like most kids, I suppose, I mistreated bugs terribly. But many adults continue the rampage against insects, and I have often found that they do this mindlessly.
With the weather getting warmer, more bugs are getting into our houses. We also spend more time in "their house," as we enjoy the great outdoors. We find ourselves reaching for the fly swatter and insecticides（杀虫剂）to get rid of them. But why do we do this? Most insects pose no threat to us, but we kill them anyway.
As a young adult, I found myself questioning my treatment of bugs. It became a moral issue. I remember reading a Native American story about a mother who saw her daughter stomp on a spider. The mom simply asks the child: "Now who'll take care of that spider's children? Who would take care of you if someone killed me?" It became a powerful lesson to the child.
All creatures have a purpose, and our world would be terribly out of balance without insects. If we can treat them with kindness and respect, we can treat any creature that way. The more I learned about the unique behaviors and purposes of insects, the more I appreciated their place in the world. I have literally become someone who "wouldn't hurt a fly."
The more I have practiced, the better I've become at catching flies with my hand and escorting them back outside. I use a small glass with a thin piece of cardboard to catch spiders, ants, and bees, and release them where they'll be happier--outdoors. Sure it takes more work than just squishing them, but I feel more in harmony with nature by being kind to bugs. If we could model that for our kids, perhaps they'd grow up to be kinder adults and help make this a kinder world to live in.
49．According to the author, many adults kill bugs ___________.
A．because they hate bugs B．to stop bugs spread diseases
C．just out of their cruelty D．just for no special reason
50．The author mentions a Native American story in the third paragraph in order to___________.
A．tell readers the importance of protecting insects
B．show its deep influence on the author
C．appeal to readers to look after spiders’ children
D．describe American mother’s kindness to insects
51．Suppose a bug appears in the author’s room, he will probably___________.
A．kill it without hesitation B．catch it and free it outside
C．drive it outside tenderly D．let it be and not disturb it
52．Which of the following would be the best title of the passage?
A．Showing kindness to insects B．My childhood and insects
C．The significance of insets D．Some tips of treating insects

第二部分：阅读理解（共25小题；每小题2分，满分50分）
第一节阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
Ever since she was a baby, Heather, aged 5, has watched her parents regularly turn off lights
that aren’t needed and put the day’s newspapers cans, bottles, jars, and other recyclables into a big, yellow bin — that is, if they can't find a second life for the discarded items in their own home first. Plastic packaging, pieces of cardboard, scraps of colored paper, bits of yarn, and small pieces of broken toys are typically dropped into a basket that the whole family rummages through whenever they need supplies for an art project. Recently, after spying a bit of shiny paper on the floor, Heather picked it up and said, "This is pretty. I'll put it in the art basket." Already, like parents, like daughter.
Heather's effort to recycle a scrap of paper rather than throw it away is a tiny gesture with a big message. It shows that even young children can learn about conserving materials and resources, and by extension, protecting the planet, in age-appropriate ways. It also shows that your child is so tuned in to your ways that it is easy to become an environmental role model. But because children are more apt to want to care for something they have a personal stake in, it's as important to expose your child to the natural world as it is to teach her ways to protect it.
This doesn't require week-long camping trips into the wilderness — although those can be fun, enlightening experiences for the whole family. Children can explore, appreciate, and learn about nature literally in their own backyard, in a park, in a community garden, and on trips to the beach or mountains. There's more good news: Giving your child opportunities to connect with nature can also help her develop crucial literacy, language, math, science, social studies, art, problem-solving, and research skills.
