Unbelievable view appealed to me by accident.Just then, I checked once again: the somewhat tiny wood was having a leaf.Could I trust my own eyes? Had the hot sun annoyed me? After all, it  as summer in Costa Rica, a country in Central America.
I left off, wiping sweat from my eyes.Then I moved the wood with my finger.It stopped.It looked up at me with big triangular eyes.Surprise! It was a mantid, a kind of insect, instead of a piece of wood.
The mantid was hanging upside down on a branch.Its wings made it look like a piece of tree bark.Then I noticed something else.The leaf wasn't a leaf at all.The hungry mantid was really eating another insect—a katydid.By now, all that was left of the katydid was a pair of wings.A few moments later, the wings dropped to the ground.The mantid folded its long legs.It sat still.Now it looked even more like a piece of wood than when I had first seen it.
I thought about how I had been fooled by these clever animals.Then I thought about how the two insects go about trying to trick each other.Both mantids and katydids are masters of make-up.Katydids are particularly good at it.Many look like something they are not.Katydids often look like plants.Many seem to be leaves.Others look like leaves of grass.All day, the bugs try to stay perfectly still.Because their bodies look like plants, most animals interested in killing them don't bother them while katydids eat plants.

Heading off to college this year? Here are some fashion tips from our experts you should keep in mind:
Dress to impress: Stylist and business consultant Daniela Smith says, “Girls should keep in mind that your college professors will often be the bridge that connects you to your future career and your classmates will become your professional network. You don’t need to dress like you’re going to the office, but you should display an ability to properly present yourself with appropriate maturity and confidence, and look put together.”
Logo mania (品牌狂热症): Wearing the logos of brands aimed at younger customers physically identifies you as part of that age group, so consider the targeted age group of the stores you shop at. It’s tempting to load up on logos, especially well-known logos that signify high-end brands. But consider this: college is a time of self-discovery, a chance to develop your own personal style. Instead of wearing logos head to toe, “walking advertisement”-style, why not express who you really are?
Wear real pants! The combination of leggings and baggy shirts is all too common on college campuses. Smith points out that leggings, yoga pants, and sweatpants are entirely unacceptable in public unless you’re exercising. Although leggings worn as pants are a common trend among high school and college girls, they are not an appropriate choice for daywear. As a young woman, your style choice should begin to reflect your maturity level. So, get rid of leggings and wear real pants!
Keep the cute factor to a minimum: Stay away from sweaters and T-shirts with smiling animals, cartoon characters, or Hello Kitty on them. Sure, kittens might be cute, but they’re not doing you any favors in the style department. Dressing too cutesy can take years off your look, and not necessarily in a good way!
小题1:The second paragraph indicates the importance of ________.
A.impressing professors
B.getting on well with classmates
C.creating a professional image
D.dressing appropriately
小题2:The author believes that college girls should ________.
A.choose a logo that suits their age
B.try to load up on well-known logos
C.use logos to show who they are
D.find their identity by trying different logos
小题3:The author recommends wearing real pants because ________.
A.leggings and baggy shirts are too common
B.yoga pants and sweatpants are not as comfortable
C.real pants can present you with appropriate maturity
D.people like real pants better than the other pants
小题4:What’s the writer’s attitude towards sweaters with animals on them?
A.They make people look lovely.
B.They are very fashionable these days.
C.They will show you’re an animal lover.
D.They are not suitable for college-aged students.
小题5:In which magazine would you most likely find this passage?
A.Business Week.B.Parents.C.In style.D.Travel & Leisure.

The “Sepik Spirit”, constructed in 1989, is built specially to suit the demands of a shallow riverboat for guiding inland waterways. Its shallow draft allows passengers into distant corners of the Sepik Region and areas not otherwise accessible to larger boats. It was refurbished(装修) in early 2006 to ensure that the Sepik Spirit meets the expectations of the modern travellers. The refurbishment includes new interior and improved noise resistance.
The Sepik Spirit holds 18 passengers in 9 twin bedrooms each with private bathroom. Onboard facilities include a dining room, living room, bar, video and covered upper observatory deck(甲板). The entire boat is air-conditioned. Because the Sepik Spirit is designed to operate in this unique environment, she is the ideal size for exploration. This, combined with small passenger numbers, allows the travellers an excellent experience to little visited areas.
Day trips from the Sepik Spirit are done in an 18-seater riverboat, also designed for the operation. Their open-air design gives the travellers a sense of place, a feeling for the river and its people.
Areas that the Sepik Spirit and her guests may visit are the Karawari River, Blackwater Lakes, Chambri Lakes, the Middle Sepik and the Upper Sepik. The river banks where the boat operates are dotted with many large traditional villages each with its own unique “Haus Tambaran” or spirit house decorated with ancestral figures.

Volunteering can help you deal with stress and problems, have more confidence, and introduce you to exciting new ideas and people. But what kind of volunteering should you do?
Firstly, think about what you enjoy. What are you interested in? What do you want to be when you grow up? For example, if you love animals, you can volunteer to care for abandoned(被遗弃的) pets or injured wildlife. If you want to grow up to be a doctor or a nurse, you can look for a youth volunteer program at a local hospital.
Secondly, think about what you’re good at. What skills do you have? What kinds of jobs do you do best? Try to find a volunteer position that will let you make the most of your strengths and talents. For example, if you’re a great speaker, then you could try educating others about a problem you care about. If you’re a cook, you might find a way to help feed hungry people in your area.
Thirdly, look for what your own community needs. What should be improved in your town, city, or school? What types of volunteer projects would do the most good? For example, if there are a lot of homeless people in your area, you could raise money to help them. If your town has empty areas filled with dirt or rubbish, you could organize or join a group to plant trees and flowers to make these areas more attractive.
The problems of the world, or even just of your community, might seem gigantic. Some people might even feel like there’s no point trying to do anything, since what they can contribute seems so small. But every person is important, and can do some good and make a difference. Like you!

Where do most writers get their ideas? For Yoshiko Uchida, it all began with Brownie, a five-month-old puppy. So excited was Yoshiko by Brownie’s arrival that she started keeping a journal, writing about all the wonderful things Brownie did and the progress he made.
Soon she was writing about other memorable events in her life, too, like the day her family got their first refrigerator. She also began writing stories, thanks to one of her teachers. Yoshiko wrote stories about animal characters such as Jimmy Chipmunk and Willie the Squirrel. She kept on writing, sharing the kitchen table with her mother, who wrote poems on scraps of paper and the backs of envelopes.
Yoshiko grew up in the 1930s in Berkeley, California. Her parents, both of whom had been born in Japan, provided a loving and happy home for Yoshiko and her sister. They also provided a stream of visitors to their home who later found their way into Yoshiko’s stories. One visitor who later appeared in several of Yoshiko’s stories was the bad-tempered Mr. Toga, who lived above the church that her family attended. Mr. Toga would scold anyone who displeased him. The children all feared him and loved to tell stories about how mean he was and how his false teeth rattled (咯咯响) when he talked.
Yoshiko also included in her stories some of the places she visited and the experiences she had. One of her favorite places was a farm her parents took her to one summer. The owners of the farm, showed Yoshiko and her sister how to pump water from the well and how to gather eggs in the henhouse. They fed the mules that later pulled a wagon loaded with hay while Yoshiko and the others rode in the back, staring up at the stars shining in the night sky. Yoshiko, who lived in the city, had never seen such a sight. As Yoshiko gazed up at the stars, she was filled with hope and excitement about her life. The images of that hayride stayed with her long after the summer visit ended, and she used them in several of her stories.
The experiences Yoshiko had and the parade of people who marched through her young life became a part of the world she created in over twenty books for young people, such as The Best Bad Thing and A Jar of Dreams. Because of such books, we can all share just a little bit of the world and the times in which this great writer grew up.
小题1:The author tells about Mr. Toga’s false teeth in Paragraph 3 in order to ____________.
A.show health care was not good enough in Berkeley during the 1930s
B.provide an interesting detail in Yoshiko’s life and stories
C.show Yoshiko’s young life was difficult and frightening
D.tell about a beloved relative who helped Yoshiko learn how to write
小题2:In Paragraph 4 “the stars” probably refer to ____________.
A.family relationshipsB.terrors in the night
C.limitless possibilitiesD.sacrifices to benefit others
小题3: What does the underlined part in the last paragraph mean?
A.Yoshiko loved to write about parades.
B.Yoshiko met many interesting people.
C.Yoshiko liked to go for long walks with others.
D.Yoshiko preferred to talk to her pets instead of to people.
小题4:What is the main idea of this story?
A.People who live in the city should spend as much time as they can in the country.
B.Writers like Yoshiko Uchida must communicate with as many writers as possible.
C.Those who move to the United States often miss their homelands for many years.
D.Writers like Yoshiko Uchida look to the richness of their lives for material.

A patient came to see me about the stress in her life. She described all the things she had to do -one was to make her bed-from the moment she woke up until she flew out of the door for work. I suggested she experiment by not making her bed for two weeks. She was shocked, probably thinking I’d been raised by wolves in a forest. However, she went along with my idea.
Two weeks later she went into my office beaming. She had left her bed unmade for the first time in 42 years-and nothing bad had happened. “And you know what?” she said. “I don’t dry my dishes anymore, either.”
This woman had made two major breakthroughs (突破). One was discovering that she had choices in her life that she had never seen before. The other was giving herself permission to be less that perfect. This story shows an important principle (原理) about managing time: No one can do it all. Each of us has to make choices and accept trade – offs. The problem is, many people choose in ways that put themselves and their health last. They take better care of their houses and cars than they do of themselves. They put everyone else’s needs ahead of their own.
So what is the solution? There’s an easy way. Decide what you want in your life, and put that first. On a daily basis, that should include regular meals, enough sleep and time with your family. Exercise, leisure, friendships and hobbies should also be regular aspects of life. The point is to do something for yourself every day. The choice is yours: whatever makes you feel good about yourself and your life. Take a nap. Take a walk. Take time to play the piano. Stop bringing your briefcase home from the office. Stop keeping your house as clean as your mother kept hers. Fill more of your time with want – to – dos instead of have – to – dos.
小题1:What is the solution to the problem of managing time?
A.Doing more exercises every day.B.Taking time to visit friends regularly.
C.Stopping making bed occasionally.D.Doing what you want to do first.
小题2:What does the word “beaming” in Line 1, Paragraph 2 probably mean?
A.WorryingB.SmilingC.DepressedD.Luckily
小题3:What is the major problem of most people managing time?
A.Most people do not take care of their health.
B.Most people put others’ needs ahead of their own.
C.Most people cannot keep balance on managing time.
D.Most people do not take time to relax themselves.
小题4:What is the author’s attitude toward people’s problems in the passage?
A.Matter – of – fact.B.Negative.C.Indifferent.D.Worried.

       It takes courage to stand up at work.Now more and more people are standing up when they are working on something important.Standing up is in fashion.Medical researchers have found that people who stand at work tend to be much healthier than those who sit.But I wasn't just looking for better health — standing would also improve how I work and relax my body.
In recent years, many office supply companies have begun to sell adjustable desks.These so-called "sit / stand" models are equipped with an electric motor that lets them shift from chair height to person height at the push of a button.Unfortunately, sit / stand desks tend to be expensive, hard to find and not very easy to test in person.
I discovered that when I worked standing up, my mind was clearer and new ideas kept coming to me.I suspect that this is because when you're standing, you feel a bit unchained from your desk.If I got stuck on a word or sentence as I wrote it, I found myself shaking my arms, bouncing (跳) on my feet or stepping away from the desk for a bit — things I couldn't do in a chair.Often, standing up seemed to relax my mind enough for me to get over creative barriers.
There's another thing about standing for a long time: I tend to get hungrier than I do when I sit on a chair.That feels like confirmation(证实) of the stand-up advocates’ belief that you burn more calories when you stand than when you sit.For this reason alone, I' m hoping that one day mass-market furniture companies can make many low-priced versions of sit / stand desks.We could all work with a bit more standing up.
小题1:The author likes standing up while working because __________.
A.he wants to show that he has a lot of courage
B.researchers say standing makes one healthier
C.he intends to catch up the fashion trend
D.he hopes to improve his work and relax himself
小题2:It can be inferred from the text that   ________.
A.adjustable desks are mass-produced now
B.adjustable desks are easy to operate
C.cheaper adjustable desks will soon be available
D.adjustable desks can be tried out easily
小题3:What is the main idea of the text?
A.Standing up at work is a better choice.
B.Standing up at work takes courage.
C.Standing up at work burns more calories.
D.Standing up at work will replace traditional sitting.
