Have you ever been afraid to talk back when you were treated unfairly? Have you ever bought something just because the salesman talked you into it?
Many people are afraid to assert（維護(hù)，堅(jiān)持） themselves. Dr. Robert Albert, author of STAND UP, SPEAK OUT and TALK BACK, thinks it is because their self-respect is low. “There’s always a superior around------ a parent, a teacher, a boss who knows better.” But Albert and other scientists are doing something to help people assert themselves.
They offer assertiveness training courses, A. T. for short. In the A. T. course people learn that they have a right to be themselves. They learn to speak out and feel good about doing so. They learn to be aggressive without hurting other people.
In one way, learning to speak out is to get rid of fear. A group taking an A. T. course will help the timid person to lose his fear. But A. T. uses an even stronger motive to share the need. The timid person speaks out in the group because he wants to tell how he feels.
Whether or not you speak up for yourself depends on your self-respect. If your face is more important than you, you may feel less of a person. You start to doubt your answers to problems. However, once you get to feel good about yourself, you can learn to speak out.
小題1:The problem the writer talks about is that ________________.
A．some people buy things they don’t want
B．some people are afraid to speak up for their rights
C．there are too many superiors
D．some people don’t think enough of themselves
小題2:The cause of the problem talked about in the text is that _________.
A．some people have a low self-respect
B．there is always someone around who knows better
C．salesmen talk people into buying things they don’t want
D．people don’t share enough
小題3:The underlined word “timid” probably means “___________” in Chinese
A．膽小的B．優(yōu)秀的
C．勇敢的D．無(wú)知的
小題4:One thing the A.T. course doesn’t do is to _____________.
A. share the need of people        B. show people they have a right to be themselves      
C. help people overcome fear      D. help people to assert themselves even if others suffer

“Dr.Papaderos,what is the meaning of life?”
The usual laughter followed,and people stirred(騷動(dòng))to go.Papaderos held up his hand and stilled the room and looked at me for a long time,asking with his eyes if I was serious and seeing from my eyes that I was.
“I will,answer your question.”
Taking his wallet out of his hip pocket,he fished into a leather billfold and brought out a very small round mirror,about the size of a quarter.And what he said went like this:
“When I was a small child,during the war,we were very poor and we lived in a remote village.One day,on the road,I found the broken pieces of a mirror.A German motorcycle had been wrecked in that place.
I tried to find all the pieces and put them together,but it was not possible,so I kept only the largest piece.This one,and,by scratching it on a stone.I made it round. I began to play with it as a toy and became fascinated by the fact that I could reflect light into dark places where the sun would never shine——in deep holes and crevices(裂縫)and dark closets. It became a game for me to get light into the most inaccessible places I could find.
I kept the little mirror,and,as I went about my growing up,I would take it out in idle moments and continue the challenge of the game.As I became a man,I grew to understand that this was not just a child’s game but a metaphor for what I might do with my life.I came to understand that I am not the light or the source of light.But light——truth,understanding,knowledge——is there,and it will shine in many dark places only if I reflect it.
I am a fragment(碎片)of a mirror whose whole design and shape l do not know.Nevertheless,with what I have I can reflect light into the dark places of this world——into the black places in the hearts of men—and change some things in some people.Perhaps others may see and do likewise.This is what I am about.This is the meaning of my life.”
小題1:On hearing the author’s question,Dr.Papedotes       at first.
A．laughed at his foolishnessB．wasn’t sure of the answer
C．doubted his seriousnessD．wasn’t interested at all
小題2:How did Dr.Papaderos get the small round mirror when he was a child?
A．He found it on the road and made it round.
B．A dying German soldier gave him as a present.
C．He chanced to find it in the street while playing.
D．He put the broken pieces together and made it.
小題3:Why did Dr.Papaderos like the small round mirror so much as a child?
A．Because he was too poor to afford other toys.
B．Because it could shine the places where tke sun couldn’t reach.
C．Because he believed it would bring good luck to him.
D．Because it tofd him a lot about what life really meant to him.
小題4:The underlined“metaphor”in the 7th paragraph most probably means       .
A．symbolB．sourceC．lightD．purpose
小題5:Which of the following might be the best title for the passage?
A．A Special Game in the ChildhoodB．A Broken Piece of Mirror

Detectives often look for footprints when they try to solve crimes. Scientists use footprints, too—dinosaur footprints when they try to figure out how dinosaurs lived and moved.
Dinosaurs died out about 65 million years ago. Today scientists work to solve the mysteries of these ancient animals.
Footprints, or tracks(腳印), are an important way to learn about dinosaurs. Christian Meyer of the Natural History Museum in Basel, Switzerland, calls dinosaur tracks “the closest thing to a movie” of dinosaurs.
“They tell us something about the size of the animal, the way they were walking…they tell us something about their speed,” Meyer said.
Tracks also show that dinosaurs sometimes traveled in groups. Traveling in groups probably helped dinosaurs protect themselves from enemies. Plus, some meat-eating dinosaurs may have hunted in groups, much like wolves do today. Being in a group could help dinosaurs work together to kill large animals.
Dinosaur footprints can be as small as a few inches across, but they can also be as big as a few feet across. Dinosaur footprints have been found throughout the world at over 1,500 sites, including a T. Rex footprint in New Mexico. “Trackways” are groups of footprints.
And scientists aren’t the only ones finding dinosaur tracks—kids can, too! Eleven-year-old Mark Turner and nine-year-old Daniel Helm discovered dinosaur tracks in British Columbia, anada. Soon scientists began studying the tracks.
Scientists and other people interested in studying dinosaurs are working to save the trackways from activities like construction and mining.
小題1:The passage mainly tells us that_______.
A. there were really dinosaurs on the earth millions of years ago
B. dinosaurs were the most frightening animals in the past
C. dinosaur footprints are important in learning about dinosaurs
C. why dinosaurs died out millions of years ago
小題2:By studying footprints scientists can know the following EXCEPT _______.
A．how big the dinosaur wasB．what color the dinosaur was
C．how fast the dinosaur could runD．how the dinosaur walked
小題3: By working in groups, some meat-eating dinosaurs_______.
A．made the hunting of large animals easily
B．could travel a long way without being lost
C．could protect themselves from being hunted by wolves
D．could get to a place faster
小題4: From the last paragraph we can infer that some human activities like mining_______.
A．a(chǎn)re helpful to the study of dinosaurs
B．can help scientists solve many mysteries
C．can lead to the discovery of the footprints
D．can destroy the footprints of the dinosaur

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 (品牌狂熱癥): 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!
小題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
小題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
小題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
小題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.
小題5:In which magazine would you most likely find this passage?
A．Business Week.B．Parents.C．In style.D．Travel & Leisure.

科目：高中英語(yǔ) 來(lái)源：不詳 題型：閱讀理解

Height is just one of the thousands of features your genes(基因)decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too, but if you have questions about how tall you're going to be, ask your doctor if he or she can help you find it out.
But genes don't decide everything. For example, eating an unhealthy diet can keep you from growing to your full potential(潛力). Getting plenty of sleep and enough exercise will help you grow to the expected height.
No doubt(懷疑) you're wondering how fast you should grow. It depends. There's no perfect or right answer. Generally speaking, kids grow about 2 inches (6 centimeters) a year between age 3 and the time when they start puberty (when your body starts changing and becoming more grown up).
Your doctor will know how your growth has been going over the years. Two centimeters here and 2 inches there are not nearly as important as the height you're at now, how you've been growing up to this point, and what other changes your body may be going through.
Don't be scared if you seem to have grown a lot in a very short time. Everyone has a growth spurt（高峰）during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later ——between 7 and 13 for girls and 9 and 15 for boys.
You'll usually begin to notice that you're growing faster about a year or so after your body starts to show the first changes of puberty.
小題1:If you want to know how fast and how tall you should grow, ____________.
A．you should have enough exerciseB．you can ask doctors for help
C．you should save the environmentD．You can record your growth during puberty
小題2: This passage is mainly about ____________.
A．how the genes work in your bodyB．when is the time you grow fast
C．why you look like your parentsD．how you grow to a certain height
小題3: After reading this passage, we can explain ___________.
A．how good it is to be a doctorB．how much sleep time we need
C．why genes can’t decide everythingD．what healthy diet is
小題4: Which is NOT mentioned in the passage?
A．Your height most probably depends on how high your parents are.
B．Girls’ age for starting puberty is usually earlier than that for boys’.
C．The time showing the first changes of puberty is never noticed.
D．You may be scared sometimes when you grow too fast.

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(裝修) 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. Mix with the friendly people and experience a culture that meets very few outsiders.
