Passage Three (1) Viewed from a star
in some other corner of the galaxy, Earth would be a speck, a faint blue dot
hidden in the blazing light of our sun. While our neighbors Venus and Mars would
reflect a fairly even glow. Earth would put on a little show. Earth's light
would brighten and dim as it spins, because oceans, deserts, forests and clouds
which are all too small to be seen from such a distance, reflect varying amounts
of sunlight. The variations, it turns out, are so strong and distinctive that
surprising amount of information could be taken from a simple ebb and flow of
light. Scientists at Princeton University and the Institute for Advanced Study
conducted a detailed study of Earth's reflections as a way for human scientists
to learn about distant planets that may be like our own. (2) "If
you looked at our solar system from far away, and you looked at the terrestrial
planets Mercury, Venus, Earth and Mars, one of the quickest ways to see that
Earth is unique, which is by looking at the light curve," said Ed Turner,
professor of astrophysics and a co-author of the study. "Earth has by far the
most complicated light curve." The standard thinking in the field had been that
most of the information about an Earth-like planet would come from spectral
analysis, a static reading of the relative component of different colors within
the light, rather than a reading of changes over time. Spectral analysis would
reveal the presence of gases such as water vapor, carbon dioxide and oxygen, in
the planet's atmosphere. Looking at the change in light over time does not
replace spectral analysis, but it could greatly increase the amount of
information scientists could learn, said Turner. It may indicate, for example,
the presence of weather, oceans, ice or even plant
life.

单选题Every animal is a living radiator--heat formed in its cells is given off through its skin. Warm blooded animals maintain a steady temperature by constantly replacing lost surface heat; smaller animals, which have more skin for every ounce of body weight, must produce heat faster than bigger ones. Because smaller animals burn fuel faster, scientists say they live faster. The speed at which an animal lives is determined by measuring the rate at which it uses oxy gen. A chicken, for example, uses one-half cubit centimeter of oxygen every hour for each gram it weights. The tiny shrew uses four cubit centimeters of oxygen every hour for each gram it weights. Because it uses oxygen eight times as fast, it is said that the mouse-like shrew is living eight times as fast as the chicken. The smallest of the warm-blooded creatures, tile humming-bird, lives a hundred times as fast as an elephant. There is a limit to how small a warm-blooded animal can be. A mammal or bird that weighted only two and a half grams would starve to death, h would bum up its food too rapidly and would not be able to eat fast enough to supply more fuel.
单选题On day one of my self-proclaimed Month of Gratitude, my five-year-old son woke up "bored" at 5: 15 a. m. , I spied a speeding ticket in my wife's purse, and our water heater spluttered to its death as I was getting into the shower. Ordinarily, I would have started complaining and the day would've been off to an ugly start. But this day was different. How cute my child's dimples(酒窝)are. How fetching my wife's taste for adventure. Only 29 days to go. Just a week earlier, as I struggled with the feeling that I'd been put on this earth to load and unload the dishwasher, I'd decided it was time to end my reflexive complaining. But it wasn't simply the little things that were annoying me. All of a sudden, my friends were dealing with bad news — cancer diagnoses, divorce, job loss. Shouldn't I be celebrating my relative good fortune? I'd heard about the feel-good benefits of a gratitude attitude. Hoping for tips, I called professor Emmons, who pioneered research on the benefits of positive thinking. Emmons quoted new studies that indicated that even pretending to be thankful raises levels of the chemicals associated with pleasure and contentment. He recommended keeping a log of everything I'm grateful for in a given week or month. I followed his suggestions, but my first attempts at keeping a gratitude list were pretty weak: coffee, naps, caffeine in general. As my list grew, I found more uplift: freshly picked blueberries; the Beatles' White Album; that I'm not bald. By day three, I was on a tear, thanking every grocery bagger and parent on the playground like I'd just won an Oscar and hanging post-it notes to remind myself of the next day's thank-you targets: the mailman, my son's math teacher. But soon, the full-on approach started to bum me out. Researchers call it the Pledge of Allegiance effect. " If you overdo gratitude, it loses its meaning or, worse, becomes a chore," professor Emmons told me when I mentioned my slump. Be selective, he advised, and focus on thanking the unsung heroes in your life. Then professor Emmons suggested a " gratitude visit. " Think of a person who has made a major difference in your life and whom you've never properly thanked. Compose a detailed letter to him or her that expresses your appreciation in concrete terms, then read it aloud, face-to-face. I immediately flashed on Miss Riggi, my eighth-grade English teacher. She was the first one to open my eyes to Hemingway, Faulkner, and other literary giants. To this day, I am guided by her advice("Never be boring"). I booked plane tickets to my hometown, Scranton, Pennsylvania. Miss Riggi was shorter than I remember, though unmistakable with her still long, black hair and bright, intelligent eyes. After a slightly awkward hug and small talk, we settled in. I took a deep breath and read. "I want to thank you in person for the impact you've had on my life," I began. "Nearly 30 years ago, you introduced my eighth-grade class to the wonders of the written word. Your passion for stories and characters and your enthusiasm for words made me realize there was a world out there that made sense to me. " And whether it was Miss Riggi's enormous smile when I finished the letter, or the way she held it close as we said goodbye, my feeling of peace and joy remained long after I returned home. Since then, I have written several more gratitude letters, and my wife and I both summon our "training" when we feel saddled by life. The unpleasant matters are still there, but appreciation, I've learned, has an echo — and it's loud enough to drown out the grumbling of one man emptying the dishwasher.

单选题Analysts have had their go at humor, and I have read sortie of this interpretative literature, but without being greatly instructed. Humor can be dissected, as a frog can, but the thing dies in the process and the innards (内在部分) are discouraging to any but the pure scientific mind. In a newsreel theatre the other day I saw a picture of a man who had developed the soap bubble to a higher point than it had ever before reached. He had become the ace soap bubble blower of America, had perfected the business of blowing bubbles, refined it, doubled it, squared it, and had even worked himself up into a convenient lather. The effect was not pretty. Some of the bubbles were too big to be beautiful, and the blower was always jumping into them or out of them, or playing some sort of unattractive trick with them. It was, if anything, a rather repulsive sight. Humor is a little like that: it won't stand much blowing up, and it won't stand much poking. It has a certain fragility, an evasiveness, which one had best respect. Essentially, it is a complete mystery. A human frame convulsed with laughter, and the laughter becoming mysterious and uncontrollable, is as far out of balance as one shaken with the hiccoughs or in the throes of a sneezing fit. One of the things commonly said about humorists is that they are really very sad people—clowns with a breaking heart. There is some truth in it, but it is badly stated. It would be more accurate, I think, to say that there is a deep vein of melancholy running through everyone's life and that the humorist, perhaps more sensible of it than some others, compensates for it actively and positively. Humorists fatten on trouble. They have always made trouble pay. They struggle along with a good will and endure pain cheerfully, knowing how well it will serve them in the sweet by and by. You find them wrestling with foreign languages, fighting folding ironing boards and swollen drainpipes, suffering the terrible discomfort of tight boot (or as Josh Billings wittily called them, "tire boots"). They pour out their sorrows profitably, in a form that is not quite a fiction not quite a fact either. Beneath the sparking surface of these dilemmas flows the strong tide of human woe. Practically everyone is a manic depressive of sorts, with his up moments and his down moments, and you certainly don't have to be a humorist to taste the sadness of situation and mood. But there is often a rather fine line between laughing and crying, and if a humorous piece of writing brings a person to the point where his emotional responses are untrustworthy and seem likely to break over into the opposite realm, it is because humor, like poetry, has an extra content. It plays close to the big hot fire, which is Truth, and sometimes the reader feels the heat.
单选题The school shooting triggered a barrage of transparently irrelevant proposed solutions, tossed out without regard to their relevance to the events that supposedly ______ the proposals.
单选题MADONNA seems like a person used to getting her own way. So the pop star must have been dismayed when a court in Malawi refused to her request to adopt a three-year-old girl, Chifundo James. A judge ruled on Friday April 3rd that the adoption of Chifundo could not go ahead because Madonna had not fulfilled residency requirements. The last time Madonna tried to adopt a Malawian child she met with more success and a heap of criticism.
By plucking David Banda from grinding poverty in Malawi in 2006 she provoked mixed reactions. Some praised the singer for offering a child an escape from a life of misery. Others suggested that the pop queen might have used her wealth and stardom to bypass usual procedures and jump the queue. Detractors also suggested that it was wrong to take David away from his country of birth and his remaining family. The criticisms grew louder when it emerged that David was not, in fact, an orphan.
That circumstance is not particularly uncommon. Children given up for adoption often do have a surviving parent but one who cannot provide adequate care. David"s father was still alive but gave him up to an orphanage where he hoped his offspring would have a better life.
The number of families from rich countries wanting to adopt children from poor countries has grown substantially in the past 30 years. And there is little shortage of children who need additional help. In 2005 it was estimated that there were 132m children who had lost at least one parent in sub-Saharan Africa, Asia, Latin America and the Caribbean. Around 13m of these had lost both parents, although most of them lived with extended family.
But difficulties abound. (Would-be parents) typically want to adopt a healthy, young, orphan, usually a small baby. Older children, or those who suffer chronic illnesses, are not in demand.
Governments are understandably uneasy about outsiders removing their citizens. And as demand for children to adopt has grown, so have examples of abuse, including cases of children who have been kidnapped or parents who have been coerced or bribed. The absence of effective international regulation also allows middlemen to profit from the demand for children to adopt.
The Hague Convention on Inter Country Adoptions is intended to regulate international adoptions. It states that these can only go ahead if the parents" consent, where applicable, has been obtained without any kind of payment or compensation. Costs and expenses can be paid, and a reasonable fee may go to the adoption agency involved, but nothing more.
