There are purple clothes， purple handbags， purple bicycles， purple furniture， even purple computers! So purple is one of the most（1） colors today． But in the past， purple was a very expensive and unusual color． Let's take a look at the rich（2） of the color purple．
Some scientists believe that the first plants to appear on Earth over 500 million years ago（3） looked purple， not green． Plants today are green because（4） use green chlorophyll （叶绿素） to produce energy． （5） these early plants probably used something called retinal， which is a dark purple color．
During the time of the Roman Empire （37BC﹣476AD）， it was very（6） to make purple dye （染料）． The dye came from sea snails （海螺）．But 10，000 dead sea snails（7） you just one gram （克）of purple dye…as well as a very bad smell! This（8） purple dye was called Tyrian purple， and it was the preferred（9） of emperors．
In 16th﹣﹣century England， purple was（10） for the kings family members． Queen Elizabeth I's clothes were purple， but ordinary people were not allowed to（11） the color．
In 1856， William Perkin， an 18﹣year﹣old（12） student， noticed something strange while doing an experiment （实验）． The chemicals （化学药品） he used to clean his instruments（13） with the chemicals he used in his experiment and produced a bright purple color． This（14） led Perkin to start a company using this chemical mixture to make purple dye． The dye was much（15） than sea﹣snail dye． Thanks to Perkin， now anyone can afford to wear purple clothes．

What good language learners do
There's no such thing as being born "good at languages"． However， some people can learn languages well． It only has something to do with their attitude （态度） and the way they learn languages．
Good language learners aren't afraid to take risks．
A friend of mine can speak English， French and some other languages． I asked her what was the most important thing in learning a language． She answered at once， "Courage．"
Good language learners face the fear of making mistakes， but they are not afraid．
Good language learners are actively involved （投入）in learning process （过程）．
Good language learners take responsibility （负责） for their own learning． They create chances to use the language． They know practice is very important． They do not expect to learn the language only in the classroom． They look for creative ways to try out what they have learned．
Good language learners are good detectives．
Good language learners are always looking for clues to help themselves understand how the language works． They make guesses and ask people to correct them if they are wrong．They compare what they say with what others say． They record what they have learned and think about it．
Good language learners try to think in the language．
Good language learners prefer to think in the language． Though thinking in the language may not be easy at first， it is worth cultivating （培养）． To help them think in the language， they can carry on with a dialogue when walking along， sitting on a bus， or taking a break from other studies． Use the language whenever and wherever they can．

People have been using the wind energy for a long， long time． More than 5，000 years ago， ancient Egyptians made boats powered by the wind． In 200 B．C．， people used windmills （风车） in China．
Today， we collect the wind's energy with wind turbines （涡轮）． A turbine is similar to a windmill；it is a very tall tower with two or three blades （叶片） at the top． These blades are turned by the wind．The blades turn a generator （发电机） located inside the tower， which creates power．
Groups of wind turbines are known as wind farms． Wind farms can be found near farmland，in narrow mountain passes， and even in the ocean， where there are stronger winds．Wind farms create power for nearby homes， schools and other buildings．
In places like the Midwest and along coasts， winds can provide cheap power． Another great advantage of wind power is that it is a clean form of energy． Wind turbines do not burn oil or coal and do not pollute the air．
Wind is not always an ideal source of energy， however． Wind speed changes from time to time， depending on the time of day， weather and location． Wind turbines can be also dangerous for bats and birds．These animals cannot always tell how fast the blades are moving and crash into them．
Title： （1） Energy

Ancient times |
People in Egypt made wind﹣powered boats（2） 5，000 years ago． People in China used windmills in 200 B．C． |
|
Modern times |
It is（3） with turbines， which are tall windmill﹣like towers with two or three blades at the top and a generator inside． The wind turns the blades and the blades tum the generator to create power． |
|
Advantages |
Winds produce power at a low（4） in certain areas． Wind turbines do not cause air pollution． |
|
Disadvantages |
Wind speed does not remain at the same（5） all the time． Wind turbines can be dangerous for animals like bats and birds． |
Sometimes we fall in love with something at once and sometimes it takes long．The same is true with poems．If we're lucky（1）e ， we open a book and find a poem that attracts us at once．But usually we need to spend a little（2）t or make a little effort to truly understand a poem， Today I′d like to talk about reading poems in ways that make the experience better．
Reading a poem repeatedly will deepen your understanding of it．Sometimes a poem that seems（3）b on first reading becomes interesting with more reading．A poem that feels meaningless becomes deeper and more meaningful．
And sometimes you′re just not in the right mood the first time you read a poem， but（4）l it touches your heart．
Keep a（5）d at hand when you are reading poems． Poets like to use unusual words．Instead of skipping over（跳过） these words or trying to（6）g their meanings， look them up．
Read aloud and listen to the poem．Reading aloud will make the poem′s thythm clear．Besides，a poet′s reading is very helpful（7）b we can understand the poem's meanings from where the poet places emphasis（强调） or pauses（停顿）．
After you finish reading a poem， take a few moments to consider（8）w it is saying．Sometimes its meanings are better understood（9）t repeated reading．Other times they need our careful and deep thought on a poem．
It is（10）h to say whether there's a right or wrong way to read poems， but reading practices will enrich your experience， increase your enjoyment， and deepen your understanding of any poem．
Noisy neighbors are a common problem in a society where many people live closely together．And this can be most important when you share walls，floors or ceilings with neighbors in a fat．A noisy neighbor can make life challenging，especially if noise goes well into night，or happens during early morning hours．This situation needs to be dealt with properly，which requires your ability to keep calm．
You should first try to tell your noisy neighbors about the noise． This conversation should be polite， even friendly． It can begin with a statement like．"I am not sure you are aware"．Explain the problem in an honest way，and ask the neighbor to turn down the music，or not to hold parties until 3 a．m． You can also add that you realize they hear your noise too， and you are certainly willing to try to stop anything in your behavior that is creating extra noise．
You should know that not all neighbors are going to follow your requirement， and some may act in a bad manner． If the noisy neighbors don't change their behavior， the next step should be to write the neighbors a letter． The letter should show your grievances （不满） and the dates when the noise was quite terrible． For example， if your neighbor has loud gatherings every Friday night that last into the early morning then write down those dates．
When the noise remains going on， you should report it to local authorities （权力部门），or even the police department， when it is really necessary． Often， however， the problem is solved when the noisy neighbor knows you are going to call the police．
Do be aware that you cannot always require noisy neighbors to be quiet． When the noise remains going on， it is wise not to deal with it in an angry or retaliatory （报复性的） fashion． If you have completed the steps and letter， don't start hitting walls or moors around in your home or turning up the music to make your neighbors angry． Just have patience and remember that communication is the most important．
