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(纖弱) 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.
小題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
小題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
小題3:The red, orange or yellow light contains _____.
A．less heat than the other lightsB．more heat than the other lights
C．a(chǎn) great deal of heatD．a(chǎn) little heat
小題4:“It is a chance in a million” means_____________
A．it is commonB．it is extremely rareC．it’s luckyD．it’s impossible

Did you know that there are gifts that will multiply your happiness when you give them away? Here are five of those gifts． Giving these gifts will allow you to share with others your most unique treasure: your real self． Each gift will return to you many times．
1． Share appreciation
Tell someone how much you appreciate the faith they've shown in you． Thank them sincerely for being part of your life． Tell them how much they are needed．
Feeling appreciated is one of the most important needs that people have． When you share with someone your appreciation and gratitude, they will not forget you． Appreciation will return to you many times．
2． Share time
Balance your time expenditures （耗費(fèi)）so you can spend time with the people that you love． Support local organizations by sharing your special talents． Volunteer time for projects that benefit others in your community, country, and world．
When we slow down and observe our thoughts closely, we will sometimes uncover gifts and talents we didn't know we had． Sharing time and talents can result in discoveries that bring happiness beyond measure．
3． Share knowledge and ideas
Tell someone about a great book that you read so they can benefit from it too． Teach a new concept or idea that you've learned．
One of the best ways to strengthen new concepts in your mind is to share them with others． The more often you share what you've learned, the stronger that information will become in your memory． Sharing knowledge also provides solutions to problems． The more knowledge we share, the more knowledge we receive in return．
4． Share friendship
Acknowledge someone's strengths． Let them know that you are willing to be there when they need you． Visit someone you haven't seen for a long time． Telephone friends or relatives who live far away． Introduce two friends who don't know each other．
Bringing one individual into another's life can result in tremendous changes for both people, and for you． We succeed with the help of others． People grow by growing together． If you'd like to have many friends, then share friendship with others generously．
5． Share kindness
Perform a random act of kindness for someone: a smile, compliment, or a favor just for fun． These will multiply and spread very rapidly．
There is a powerful quote by Stephen Jay Gould who said, “The center of human nature is rooted in ten thousand ordinary acts of kindness that define our days．” Kindness is priceless． The love, kindnesses, and value we have given authentically to others will be our remaining treasures at the end of life．
Think about this statement by Norman MacEwan: “Happiness is not so much in having as sharing． We make a living by what we get, but we make a life by what we give．”

It tastes just like chicken
Away from home, eating is more than just a way to keep your stomach full．It is a language all its own, and no words can say, "Glad to meet you ．．．glad to be doing business with you ．．．" quite like sharing a meal offered by your host．
Clearly, mealtime is not the time for you to say, "Thanks, but no thanks．" Acceptance of the food on your plate means acceptance of host, country, and company．So, no matter how difficult it may be to swallow, swallow．Or, as one experienced traveler says, "Travel with a cast-iron stomach and eat everything everywhere．"
Often, the food offered represents proudly your host country’s eating culture．What would Ataiericans think of a French person who refused to take a bite of homemade apple pie or sirloin? Our discomfort comes not so much from the thing itself; it comes from our umamiliarity with it．After all, an oyster has remarkably the same look as a sheep’s eye; and a first look at a lobster would remind almost anybody of a creature from a science fiction movie, not something you dip in butter and eat．By the way, in Saudi Arabia sheep’s eyes are a famous dish and in parts of China it’s bear’s paw soup．
Can you refuse such food without being rude? Most experienced business travelers say no, at least not before taking at least a few bites．It helps, though, to slice any item very thin．This way, you minimize the taste and the reminder of where it came from．Or, " Swallow it quickly, " as one traveler recommends．"I still can’t tell you what sheep’s eyeballs taste like．" As for dealing with taste, the old line that "it tastes just like chicken" is often thankfully true．Even when the "it" is really rat or snake．
Another useful piece of advice is not knowing what you are eating．What’s for dinner? Don’t ask． Avoid glancing into the kitchen or looking at English-language menus．Your host will be pleased that you are eating the food he offers, and who knows? Maybe it really is chicken in that soup．
小題1:The purpose of the article is to ____．
A．introduce unfamiliar food
B．share the writer’s personal experiences
C．suggest ways to overcome a cultural barrier
D．a(chǎn)dvise on how to politely refuse to eat foreign food
小題2:According to the writer, people hesitate at strange food mainly due to ____．
A．the way it looksB．safety worries
C．lack of information about itD．the unfamiliar atmosphere
小題3:From the article we can infer that ____．
A．a(chǎn)n American may feel comfortable with sirloin
B．one should refuse strange food after a few bites
C．English-language menus are not always dependable
D．one needs a cast-iron stomach to travel in other cultures
小題4:One may say "It tastes just like chicken．" when ____．
A．showing respect for chicken-loving nations
B．greeting people with different dieting habits
C．evaluating chefs at an international food festival
D．getting someone to try a visually unpleasant meal

Bamboo (竹子) is one of nature’s most surprising plants. Many people call this plant a tree, but it is a kind of grass.
Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist reported one bamboo plant which grew 1.5 meters in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1, 000 kinds of bamboo.
Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimeters across. This plant also comes in different colors, from yellow to black to green.
Bamboo has been used to make many things such as hats and kitchen tools. Because it is strong, bamboo is also used to build buildings.
Many Asian countries have used bamboo for hundreds of years. They often use bamboo for buildings and supporting new buildings and bridges while they are being built.
In Africa, poor farmers are taught how to find water using bamboo.

Vans, Keds, Dollies—they sound like the names of rock bands, but if you have teenagers, you'll know they're actually the latest in teenage footwear.
But experts are now warning that the current shoe fashions will be causing teenagers discomfort in the short term and storing up years of foot, knee and back pain in the future.
Here, the experts identify the problems caused by teenagers' shoe choice.
KEDS/VANS
Slip-on shoes with elastic (彈性的）sides are particularly popular among teenage boys - with Keds and Vans the most sought-after brands.
The main problem is that they are just too flat—so flat that the heel, which strikes the ground first, also becomes damaged and painful.
BALLET PUMPS
The worst shoes of all are such light and thin dolly shoes. The problem is partly their flatness, as with Keds and Vans. However ballet pumps, which have no string or heel, have other specific problems.
“As the shoe has no fastening device, it relies on the toes to keep the shoe on, causing an awkward gait（步法）, this leads to short- and long-term problems such as calluses（繭子）, heel and knee pain.”
WEDGES AND STILETTOS
These shoes can also cause problems with gait. They may look good, but the heels on these are so high they can force the wearer's body weight forward, making them very unstable.
Teens who wear these shoes regularly are also in danger of joining those millions of women with constant back pain.
SCHOOL SHOES
So what do podiatrists（足科醫(yī)生）have on their wish list, especially for everyday wear?
Something in a natural, breathable fabric, with a string to hold it on, with a small heel and a deep toe-box that does not press the toes, such as Clark's, Marks & Spencer or Rhino.
If your teen insists on wearing 'bad' shoes, get them some simple foot orthotics(矯形器) in the shoes. These support and correct the movement of the foot and, properly fitted by a podiatrist, can often transform their walk and halt the damage.
小題1: Of all the shoes mentioned in the passage, which can cause the worst problems?
A．Marks & Spencer.B．Wedges & Stilettos.
C．Keds and Vans.D．Ballet Pumps.
小題2: Which pair of shoes may not be found on the podiatrists’ wish list?

小題3: The underlined word “halt” in the last paragraph probably means _______.
A．increaseB．worsenC．stopD．cure
小題4: From this passage we can infer _______.
A．trendy shoes may ruin teenagers’ health
B．fashionable shoes all have orthotics in them
C．experts are strongly against wearing popular shoes
D．podiatrists are expert at producing branded shoes
小題5: In which column of Mail Online can you find this passage?
A．Sports.B．Science.C．Health.D．Shopping.

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".
小題1:   According to the passage, a "warrant" is______.
A．a(chǎn)n identification card B．a(chǎn)n access card
C．a(chǎn)n official written orderD．a(chǎn) special license
小題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.
小題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
小題4: The passage centers around____.
A．the rights of citizensB．the importance of warrants
C．the duty of the policeD．criminal cases

Some years ago, on a hot summer day in south Florida, a little boy decided to go for a swim in the old swimming hole behind his house. He flew into the water, not realizing that as he swam toward the middle of the lake, an alligator (美洲鱷) was swimming toward the shore.
His father working in the yard saw the two as they got closer and closer together. In utter fear, he ran toward the water, yelling to his son as loudly as he could.
Hearing his voice, the little boy became alarmed and made a U – turn to swim to his father. It was too late. Just as he reached his father, the alligator reached him. From the dock, the father grabbed his little boy by the arms just as the alligator snatched his legs. That began an incredible tug – of – war (拔河) between the two. The alligator was much stronger than the father, but the father was much too passionate to let go. A farmer happened to drive by, took aim and shot the alligator.
Remarkably, the little boy survived. His legs were extremely scarred by the vicious attack of the animal. And, on his arms, were deep scratches where his father’s fingernails dug into his fresh in his effort to hang on to the son he loved.
The newspaper reporter who interviewed the boy asked if he would show his scars. The boy lifted his pant legs. And then, he said to the reporter, “But look at my arms. I have great scars on my arms, too. I have them because my dad wouldn’t let go.”
You and I can identify with that boy. We have scars, too. No, not from an alligator, but the scars of a painful past. Some of those scars are unsightly and have caused us deep regret. But, some wounds, my friend, are because someone has refused to let go. In the midst of your struggle, someone has been there holding on to you.
If you have the scars of someone’s love on your arms, be very, very grateful. Someone in your life did not and will not ever let you go.
Never judge another person’s scars, because you don’t know how they got them.
小題1: Which of the following is the most closely related to the underlined word “passionate”?
A．determinedB．a(chǎn)nxiousC．frightenedD．courageous
小題2:When the boy told the newspaper reporter about the scars on his arms, he felt     .
A．painful and fearfulB．regretful and panic
C．proud and gratefulD．excited and thankful
小題3:In the story the writer intends to tell us that     .
A．scars always remind people of their past experiences
B．wounds in the mind are more painful than those in the body
C．a(chǎn) painful past always leaves scars on a person’s mind
D．scars do not necessarily mean pain at all times
小題4:Which of the following viewpoints will the writer most probably agree with?
A．Be grateful to a painful past, for you can always learn something from it.
B．Other people’s criticism or blame may hurt you, but if it is for your own good, you should take it thankfully.
C．The swimming hole of life is filled with danger, but you don’t need to be too serious about it as someone will never let you go.
D．If someone hurts you, be grateful to them, for they mean no harm
