If we observe carefully, we van find that most of the flowers in nature are red, orange and yellow. If we have seen a black flower, it’s a chance in million. People have made a census(普查)to colours of more than four thousand kinds of flowers and discovered that only eight of them are black. Why?
As we know, sunlight is formed by seven different kinds of coloured light. The wave length of each light changes, so the quantity of heat in each light changes, too. Flowers, especially their petals(花瓣), are very delicate(纤弱) and prone(易于) to the harm caused by high temperature. Black flowers can take in all the light waves, which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight. But red flowers, orange flowers and yellow flowers can protect themselves from sunlight by reflecting the red light, orange light and yellow light, each of which has a large quantity of heat.
That is why red, orange and yellow flowers are very common in nature while black flowers are so rare.
小题1:We can hardly find black flowers because  _____.
A.they are so weak that it’s difficult for them to grow up
B.there are no black flowers in the world.
C.the petals of black flowers are very delicate
D.they can take in the light of all wave lengths, which make the flowers dry up
小题2: Sunlight is formed by _____.
A.many different kinds of coloured light
B.three different kinds of coloured light—red, orange and yellow
C.seven different kinds of coloured light
D.four thousand kinds of coloured light
小题3:The red, orange or yellow light contains _____.
A.less heat than the other lightsB.more heat than the other lights
C.a great deal of heatD.a little heat
小题4:“It is a chance in a million” means_____________
A.it is commonB.it is extremely rareC.it’s luckyD.it’s impossible

举一反三
Matt grows the best vegetables in the village. He grows fruit too – big, sweet apples and oranges. And what else? Well, the biggest and the prettiest flowers.
Things grow in Matt’s garden all through the year. He cuts some flowers for his sitting room table; and of course , he eats some fruit and vegetables. But he sells everything else in the market. Matt is not a poor man.
He knows a few other gardens; but he does not have any friends. You might ask, “What is that?” Why doesn’t he have friends. I will tell you. People do not understand him. And they do not understand his garden. “Why not?” You will ask. “It is a very good garden, isn’t it?” It is a wonderful garden. Matt plants things in spring, summer, autumn and winter. After that he does very little work. He sits in the garden with his small radio. And everything grows.
People ask, “How does Matt grow these wonderful things? He waters the plants sometimes, but he doesn’t do anything else. He just sits under an orange tree with his radio. He listens to music nearly all day!” and that is all quite true. People cannot understand it, and so they don’t like it very much.
Matt likes music. But what about the garden? Who does the work? I will tell you another true thing: the music does the work. All plants love music; and Matt knows that.
Do you want big vegetables and the loveliest flowers? Well, just give your plants a lot of music.

  Imagine yourself on a boat looking out at the horizon and all you can see is the water meeting the sky with no land in sight and you are sailing straight ahead to meet the world. Jesse Martin does not have to imagine: he is living in it.
On Dec. 7, 1998, at 17 years old, Jesse set sail from Melbourne, Australia on his boat, attempting to become the youngest person to sail alone and nonstop around the world. He sailed south of New Zealand, through the South Pacific, around South America, north on the Atlantic, back south past Africa, through the Indian Ocean and back to Melbourne.
Even as a young child, Jesse had been an adventurer who traveled all over Europe and Asia with his parents. Born in Munich, Germany in 1981, he moved to Australia with his family when he was only two years old. They moved close to a rainforest in Cow Bay, about 3500kms north of Melbourne, where they built a small house with no electricity or running water. Jesse grew up at the beach enjoying the outdoors to its fullest.
At 14, he sailed for the first time with his father and brother, Beau. It was after this trip that he began to dream about sailing around the world.
Jesse’s family played an important role. “I was made to believe I could do anything.” he says. Although, he says, there were others that were not so encouraging or supportive, “People that I looked up to, respected and trusted told me I couldn’t. Thankfully, I trusted myself. There were people that said that the boat couldn’t be ready by the time I had to leave.” However, through perseverance and belief in himself he was able to do what many told him was impossible.
On Oct.31, 1999, more than 10 months after he set sail, Jesse Martin went down in history as the youngest person to sail around the world alone, nonstop and unassisted.
小题1: What’s the author’s purpose in encouraging the reader to imagine a sailing experience?
A.To show how difficult it is to be a sailor.
B.To show how wonderful Jesse’s sailing is.
C.To describe what Jesse’s sailing is like.

小题2: Jesse Martin was at the end of his voyage when he _______.
A.sailed on the South Pacific.
B.sailed on the Indian Ocean.
C.sailed past Africa
D.sailed past South America.
小题3: Which of the following made Jesse decide to sail alone around the world?
A.His childhood adventure experiences.
B.His journeys to Europe.
C.His first sailing trip with his family.
D.His love for outdoor activities.
小题4: What can we learn from Jesse Martin’s story?
A.Interest leads to success.
B.A strong belief will make a person stronger.
C.Life is an unusual adventure we should enjoy.
D.Failure is the mother of success.

When you are at odds with someone close to you,the One-Minute Drill can show you how to express your feelings effectively-and how to listen more skillfully.All it requires is two individuals who are committed to improving their relationship.
Set aside at least ten minutes,and then sit facing each other.Decide who will be the Talker and who will be the Lastener.It makes no difference,because later you will change roles.
How to perform the One-Minute Drill
For approximately 30 seconds,the Talker can say anything he or she wants.Your job will be to express your thoughts and feelings.You can discuss problems you’ve had a hard time talking about.Remember to limit yourself to about 30 seconds.When the Talker finishes,the Listener will summarize what the Talker just said,as well as how the Talker was feeling inside,as accurately as possible.
The Talker now gives the Listener a grade between 0 and 100 percent to indicate how accurate the summary was.If the rating is 95 percent or more,you can change roles;the new Talker can continue with the same topic or move on to something entirely new.
However,if the grade is below 95 percent,the Talker should point out what the Listener missed or got wrong,and repeat the process until the overall rating is 95 percent or more.Then you can change roles and repeat the exercise for as long as you both like.
How it works
Thirty seconds of emotionally charged information is sufficiently challenging for anyone.Express your feelings in strong,clear,direct language,but as your partner will be listening attentively,you won’t need to shout,exaggerate or put your partner down.
The Listener should sit and listen respectfully without interrupting.Look into your partner’s eyes,but avoid using negative body language. If you like,take a few notes.
So the Talker might say:“When I come home from work, I feel tired and I need some quiet time.But you tell me I’m supposed to spend time with the kids.This makes me feel frustrated.I work hard and I’m exhausted at the end of the day.I feel like I deserve a little time to relax,not listen to more demands.”
In response,the Listener might summarize like this:“You just told me that you feel exhausted when you come home at night because you’ve been working hard all day.When l tell you l want you to spend time with the kids,you feel frustrated and ticked off because you’re tired and you need time to relax.You see me as very demanding,and you’re probably feeling like I don’t appreciate you.”
The first time you attempt the One-Minute Drill,you may get a low score.Don’t worry,because you’ll get up to speed quickly.Once you’ve tried this exercise a few times,you’ll find that you can nearly always get ratings of 95 percent or better on the first or second try.

In this age of Internet chat,videogames and reality television,there is no shortage of mindless activities to keep a child occupied.Yet,despite the competition,my 8-year-old daughter Rebecca wants to spend her leisure time writing short stories.She wants to enter one of her stories into a writing contest,a competition she won last year.
As a writer I know about winning contests,and about losing them.I know what it is like to work hard on a story only to receive a rejection slip from the publisher.I also know the pressure of trying to live up to a reputation created by previous victories.What if she doesn.t win the contest again?That’s the strange thing about being a parent.So many of our own past scars and dashed hopes can surface.
A revelation(启示)came last week when l asked her,”Don’t you want to win again?” “No,” she replied,“I just want to tell the story of an angel(天使)going to first grade.”
I had just spent weeks correcting her stories as she spontaneously(自发地)told them.Telling myself that l was merely an experienced writer guiding the young writer across the hall. I offered suggestions for characters,conflicts and endings for her tales.The story about a fearful angel starting first grade was quickly“guided”by me into the tale of a little girl with a wild imagination taking her first music lesson.I had turned her contest into my contest without even realizing it.
Staying back and giving kids space to grow is not as easy as it looks.Because I know very little about farm animals who use tools or angels who go to first grade,I had to accept the fact that I was co-opting(借用)my daughter’s experience.
While stepping back was difficult for me,it was certainly a good first step that l will quickly follow with more steps,putting myself far enough away to give her room but close enough to help if asked.All the while I will be reminding myself that children need room to experiment,grow and find their own voices.

There are many rights to make sure that people will be treated fairly when they are suspected or accused of a crime. Sometimes these rights are called "due process of law". In using these rights, a person should have the help of a lawyer.
You have a right to protect against unreasonable searches and seizures. The police generally may not search you or your home, or take things you own, without a "warrant". A warrant is a paper which states, very exactly , the place to be searched and the things to be taken. Sometimes, however, the police will not need a warrant to search you or your property. If an officer sees you committing a crime, or if he has a good reason to believe you have committed a serious crime, he may arrest you and search you and the area right around you without a warrant.
If you invite a police without a warrant to come into your house and he finds proof of crime, the evidence may be used against you in court. If you do not want an officer to search you or your home and he does not have a warrant, tell him that you do not give him the right to search. However, if the officer will not listen, do not try to stop him. It is dangerous to resist and it may be illegal to do so. Any evidence which a policeman gets during an unlawful search and seizure cannot be used against you.
Police officers must act reasonably and fairly at all times. They should use physical force only when it is needed to arrest someone to enforce a law. They may not use physical violence to "teach someone a lesson".
小题1:   According to the passage, a "warrant" is______.
A.an identification card B.an access card
C.an official written orderD.a special license
小题2:   In which case can the policeman use the evidence he gets against you in court?
A.He makes an unreasonable search of your home and gets the evidence.
B.He is allowed to search your home with no warrant and finds proof of crime.
C.He gets the information you do not want to give him by using physical force.
D.He obtains the information from you when you are alone with him.
小题3: The police can use physical force only when____.
A.they want to teach the habitual thief a lesson
B.they catch the criminal on the spot
C.the suspect talks back
D.the criminal resists arrest
小题4: The passage centers around____.
A.the rights of citizensB.the importance of warrants
C.the duty of the policeD.criminal cases
