题型：不详难度：来源：
There are many reasons for these little animals" coming to the center. First of all, street cats or dogs catch, injure or take away little birds from their nests. Sometimes people catch baby animals and keep them at home, giving them food that they are not used to. It would make them sick. Most people don"t realize that it"s against law to get live animals out of their nests.
As for songbirds, people often find them on the ground in their yards, thinking they have no other choice but to leave them on the ground to die. This is because many people wrongly believe that once a bird is touched by a person, its mother will not accept this child bird. But that"s not true.
If a little bird falls out of the nest, you should check whether it is injured. If not, you should put the bird back in the nest. If the bird is injured, call your local wildlife center quickly.
As for the progress of protecting wild animals, people at Wild Friends devote all their energy to this work. Over the last weeks, they have been able to send many of the birds and rabbits that came here earlier this spring back to nature.
小题1:Which is the busiest season for workers at Wild Friends?
| A．Spring | B．Summer. | C．Autumn. | D．Winter. |
| A．Giving them food they don"t like. | B．Letting them play with children. |
| C．Leaving them on the ground. | D．Bringing them to the center. |
| A．wait for its mother | B．help it go back home |
| C．touch it with your hands | D．call workers at Wild Friends |
答案

小题2:C
小题3:B
解析
试题分析：文章主要介绍了保护野生动物的事情。在春末的时候，野生动物中心的工人最忙，小鸟受到的影响最大。遇到小鸟从鸟巢里掉下来，应该确认是否受伤，没有的话，把它送回鸟巢；受伤的话，及时送回野生动物中心。
小题1:根据第一段“Every year in late spring at Wild Friends, ...This is the busiest time when workers care for and raise all the little ones”可知，在Wild Friends，工人最忙的季节是春季，故选A。
小题2:根据第三段“As for songbirds, people often find them on the ground in their yards, thinking they have no other choice but to leave them on the ground to die.”可知，小鸟落在地面时，人们往往会置之不顾，让它们自生自灭，这对它们来说是很危险的，故选C。
小题3:根据倒数第二段“If a little bird falls out of the nest, you should check whether it is injured. If not, you should put the bird back in the nest. If the bird is injured, call your local wildlife center quickly.”可知，无论是放回鸟巢还是送到野生动物中心，都是为了帮助小鸟回家，D项是在小鸟受伤的情况下要做的，故选B。

If you come to visit, you"ll probably be surprised when you come in: Someone will give you an electronic PIN to wear. The PIN tells the house who you are and where you are. The house uses this information to give you what you need. When it"s dark outside, the PIN turns on the lights near you, and then turns them off as you walk away from them. Music moves with you, too. If the house knows your favorite music, it plays it for you. The music seems to be everywhere, but in fact other people in the house hear different music or no music. If you get a telephone call, only the nearest telephone rings.
Of course, you are also able to want something. There is a home control console (控制台) which is a small machine that turns things on and off around you.
The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you the key to my car, you can use my car. The car works for you because you have the key. My house works for you because you wear the PIN or hold the console.
I believe that in ten years from now, most new houses will have the systems that I"ve put in my house. The systems will probably be even bigger and better than the ones I"ve got.
I like to try new ideas. I know that some of my ideas will work better than others". But I hope that one day I will stop thinking of these systems as new, and ask myself instead, ”How did I live without them?”

Now you can use your voice to use your iPhone 4S. Just talk to Siri as you would to a person: “Do I need an umbrella?” or “Where’s the closest ATM?” Siri not only understands what you say, it knows what you mean. It figures out the right apps to use to find the right answer. Then, just like a personal assistant, it answers you. Siri makes phone calls, sends messages, schedules meetings, sets reminders, and more. How much more? Just ask, and Siri tells you that, too.
Dual-core A5 chip: the most powerful iPhone ever.
Two cores in the A5 chip provide up to two times more power and up to seven times faster graphics. And you’ll feel the effects. iPhone 4S is quick and responsive, which makes all the difference when you’re launching apps, surfing the web, gaming, an doing just about everything. And no matter what you’re doing, you can keep on doing it. Because the A5 chip is so power-efficient, iPhone 4S has outstanding battery life.
FaceTime. It’s even better face-to-face.
FaceTime of iPhone 4S lets you hear a voice and see the face that goes with it—iPhone to iPhone, iPad 2, iPod touch, or Mac over Wi-Fi. So no matter where they are, no matter where you are, you’ll always be there. Making a FaceTime call is just as easy as making a phone call. And it’s even easier with Siri. Just tell Siri “FaceTime with Mom” and you show up, smile and wave hello. You’ll never miss a big event, an important meeting or a good laugh. And who wouldn’t be happy to see your face?

His study showed that bus conductors were much less likely to die of heart disease than bus drivers. Why? Because the conductors spent their working day walking. It seems obvious now but in the middle of the last century doctors were puzzled by the rising numbers of people who got heart diseases. Jerry Morris found one of the main causes: a sedentary (久坐不动的) lifestyle. He started exercising for a few minutes each day and lived until his 100th year.
If you wish to protect your heart, you have to do more than wander in the garden. The exercise needs to be reasonable. Jogging is not for everyone and a round trip to the gym takes a couple of hours, plus the monthly membership fee is only good value if you visit regularly. The answer is simple: walk.
A half-hour purposeful walk five times a week will lower your risk of heart disease, diabetes and strokes. Older people sometimes feel they have left it too late. But it is never too late to start and there are no upper age limits. Start gently. Take your time: a 15-minute flat walk in the nearest park, four or five times a week. Within a month or so, you are already beginning to protect your heart. Build the walks up. When you can comfortably walk for half an hour in the park, go further: try following rivers and canals.
Regular walkers have their own natural gymnasium. There is no membership fee, just some of the finest scenery in the world. Great Britain is the walker’s gym. When you have followed the rivers and canals, and are enjoying walking for a couple of hours, head for the coast. Once again, build it up slowly. When you are comfortable with long coastal walks, you can think of our national parks.

These experiments were conducted by psychological scientists, Nadia Chernyak and Tamar Kushnir of Cornell University. They found that sharing things with others when they are given a difficult choice leads children to think of themselves as people who like to share. It also makes them more likely to act in a pro-social （亲社会的）manner in the future.
Previous research has explained why rewarding children for sharing can backfire. Children come to think of themselves as people who don"t like to share since they had to be rewarded for doing so. Because they don"t view themselves as "sharers", they are less likely to share in the future.
Chernyak and Kushnir were interested in finding out whether freely chosen sacrifice might have the opposite effect on kids" willingness to share. To test this, the researchers introduced five-year-old children to Doggie, a sad puppet. Some of the children were given a difficult choice: Share a precious sticker（贴纸） with Doggie, or keep it for themselves. Other children were given an easy choice between sharing and putting the sticker away, while children in a third group were required by the researcher to share.
Later on, all the children were introduced to Ellie, another sad puppet. They were given the option of how many stickers to share (up to three). The kids who earlier made the difficult choice to help Doggie shared more stickers with Ellie. The children who were initially faced with an easy choice or who were required to give their sticker to Doggie, on the other hand, shared fewer stickers with Ellie. Therefore, children did not benefit from simply giving something up, but rather from willingly choosing to give something up of value.
“You might imagine that making difficult, costly choices is demanding for young children or even that once children share, they don’t feel the need to do so again,” Chernyak says. “But this wasn"t the case: once children made a difficult decision to give up something for someone else, they were more generous, not less, later on.” Chernyak concludes.
小题1:_______ helps children to share more in the future.
| A．Rewarding children for sharing |
| B．Forcing children to share |
| C．Allowing children to share precious things willingly |
| D．Allowing children to share what they don’t need |
| A．have an opposite effect | B．serve as a push |
| C．cause anger | D．avoid taking things back |
| A．they regret what they did | B．it’s not their own choice |
| C．Ellie is not as sad as Doggie | D．they like to share with a real person |
| A．parents will never find a way to get children to share toys |
| B．a gift should be given to make up for children’s sacrifice |
| C．children pretend to be generous when they are being observed |
| D．making difficult choices may influence sharing behavior |
Moss(藓类植物) found buried beneath the Teardrop glacier(冰川) on Ellesmere Island in Canada has been brought back to life. Findings suggest that these plants could help repopulate regions exposed by melting ice caps. Plants that were buried beneath thick ice in Canada more than 400 years ago and were thought to have frozen to death have been brought back to life by Canadian scientists.
Samples of the moss plant, covered by the glacier during the Little Ice Age of 1550 to 1850 AD, were replanted in a lab at the University of Alberta and grew new stems(茎). Researchers now think these findings can give indication as to how regions can recover as the ice covering them melts.
Biologist Dr. Catherine La Farge and her team at the University of Alberta were exploring the region around the Teardrop glacier on Ellesmere Island. Ice on Ellesmere Island region has been melting at around four meters each year for the past nine years. This means that many areas of land that were previously covered by ice have since been exposed. Many ecosystems that were thought to have been destroyed during the Little Ice Age between 1550 and 1850 AD can now be studied, including many species that have never been studied before.
While examining an exposed area of land, La Farge and her team discovered a small area of moss called Aulacomnium turgidum. It is a type of bryophyte(苔藓类植物) plant that mainly grows across Canada, the US and the Highlands of Scotland.
Dr La Farge noticed that the moss had small patches of green stems, suggesting it is either growing again or can be encouraged to repopulate. Dr La Farge told the BBC, “When we looked at the samples in detail and brought them to the lab, I could see some of the stems actually had new growth of green branches, suggesting that these plants are growing again, and that blew my mind. When we think of thick areas of ice covering the landscape, we’ve always thought that plants have to come from refugia(濒绝生物保护区), never considering that land plants come from underneath a glacier. It’s a whole world of what’s coming out from underneath the glacier that really needs to be studied. The ice is disappearing pretty fast. We really have not examined all the biological systems that exist in the world; we don’t know it all.”
Dr La Farge took samples of the moss and, using carbon-dating techniques, discovered that the plants date back to the Little Ice Age. Dr La Farge’s team took the samples, planted them in dishes full of nutrient-rich potting soil and fed them with water.
The samples were from four separate species including Aulacomnium turgidum, Distichium capillaceum, Encalypta procera and Syntrichia ruralis. The moss plants found by Dr La Farge are types of bryophytes. Bryophytes can survive long winters and regrow when the weather gets warmer.
However, Dr La Farge was surprised that the plants buried under ice have survived into the twenty-first century. Her findings appear in proceedings（论文集）of the National Academy of Sciences.
