When a leafy plant is under attack ，it doesn't sit quietly. Back in 1983,two scientists,Jack Schultz and Ian Baldwin,reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be an alarm.What the plants pump through the air is a mixture of chemicals known as volatile organic compounds,VOCs for short.
Scientists have found that all kinds of plants give out VOCs when being attacked.It's a plant's way of crying out.But is anyone listening?Apparently.Because we can watch the neighbours react.
Some plants pump out smelly chemicals to keep insects away.But others do double duty .They pump out perfumes designed to attract different insects who are natural enemies to the attackers.Once they arrive,the tables are turned .The attacker who are natural enemies to the attackers . Once they arrive,the tables are turned.The attacker who was lunching now becomes lunch.
In study after study,it appears that these chemical conversations help the neighbors .The damage is usually more serious on the first plant,but the neighbors ,relatively speaking ,stay safer because they heard the alarm and knew what to do.
Does this mean that plants talk to each other? Scientists don't know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to "overhear" the cry. So information was exchanged, but it wasn't a true, intentional back and forth.
Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate(亲密的) than the world we can see and hear. Our senses are weak. There's a whole lot going on.

Do you know that a fast reader can get the ideas better than a slow reader can? Of course, you save time by reading fast, but this is not the main reason for fast reading. The main reason is that you understand better what you are reading when you read fast.
As your eyes move along the line of print, they make fixations(固定) or pauses. It is important that you see several words at a fixation. It is also important that your eyes leave a group of words quickly and move on to another group. The number of letters or words that you see at a fixation is called your eye span. Pay more attention to improving your rate of reading. With practice you can learn to read faster than you usually read.
The way in which you read always depends on what you are reading and for what purpose. You should know the different ways of reading so that you can apply whatever method that is necessary. Here are four ways of reading:
(1) Skimming is an important kind of reading. This method can be used when you wish to review something that you have forgotten. You can skim to get the main points.
(2) Rapid first reading and then rereading certain parts carefully is important. You may use this type of reading to study a science lesson or a history lesson.
(3) You need to do careful reading and rereading sometimes. This type of reading is necessary for making an intensive(精深的) study of your school subjects, solving maths problems or reading directions.
(4) Rapid reading is used when reading stories for enjoyment. You may also do rapid reading when reviewing material that you already know well.The main reason for reading fast is that you canwhat you are fast reading.

Now you have a list to end all lists!
Take a look at the following two examples from the list of “101 things not to do”:
Swim with Dolphins(海豚)?
Swimming with dolphins is one of the world’s most profitable tourist activities.

Worse yet, when dolphins get too near to the boats loaded tourists, they could get caught up in ropes and killed by propellers(螺旋桨).
Here’s a little secret. Dolphins look like smiling at you, but actually they’re just opening mouths.
Go to See the Mona Lisa?
There must be something about the mysterious(神秘的) smile. The 6 million people who the lady in the Louvre every year can’t all be wrong after all. But they can be quite annoying standing in front of you, holding up their cameras to prevent you from seeing anything. In fact it is hard for you to see the painting clearly because you have to stay away from it for security read.

On the first day of college our professor introduced himself and challenged us to get to know someone we didn’t already know.
I stood up to look around when a gentle hand touched my shoulder. I turned around to find a wrinkled, little old lady beaming up at me with a smile that lit up her entire being. She said, “Hi, handsome! My name is Rose. I’m eighty-seven years old. Can I give you a hug?” I laughed and enthusiastically responded, “Of course you can!” and she gave me a giant squeeze.
“Why are you in college at such a young, innocent age?” I asked. She jokingly replied, “I’m here to meet a rich husband, get married, have a couple of children, and then retire and travel.”
“No seriously,” I asked. I was curious what may have motivated her to be taking on this challenge at her age. “I always dreamed of having a college education and now I’m getting one!” she told me.
After class we walked to the student union building and shared a chocolate milkshake. We instantly became friends. Every day for the next three months we would leave class together and talk non-stop.
I was always mesmerized(催眠) listening to this “time machine” as she shared her wisdom and experience with me. Over the course of the year, Rose became a campus icon(偶像) and she easily made friends wherever she went.
At the year end, Rose finished the degree she had begun all those years ago. One week after graduation Rose died peacefully in her sleep.

Recently a Beijing father sent in a question at an Internet forum(论坛) asking what “PK” meant. “My family has been watching the ‘Super Girl’ singing competition TV program. My little daughter asked me what ‘PK’ meant, but I had no idea,” explained the puzzled father.
To a lot of Chinese young people who have been playing games online, it is impossible not to know this term. In such Internet games, “PK” is short for “Player Kill”, in which two players fight until one ends the life of the other.
In the case of the “Super Girl” singing competition, “PK” was used to refer to the stage where two singers have to compete with each other for only one chance to go up in competition ranking.
Like this father, Chinese teachers at high schools have also been finding their students’ compositions using Internet jargons(行话) which are difficult to understand. A high school teacher from Tianjin asked her students to write compositions with simple language, but they came up with a lot of Internet jargons that she didn’t understand.
“My ‘GG’ came back this summer from college. He told me I’ve grown up to be a ‘PLMM’. I loved to ‘FB’ with him together; he always took me to the ‘KPM’,” went one composition.
“GG” means Ge Ge(Chinese pinyin for brother). “PLMM” refers to Piao Liang Mei Mei(beautiful girl). “FB” means Fu Bai(corruption). “KPM” is short for KFC, Pizza Hut and McDonald’s.
Some specialists welcome Internet jargons as a new development in language.
If you do not even know what a Kong Long(dinosaur, referring to an ugly looking female) or a Qing Wa(frog, referring to an ugly looking male) is, you will possibly be regarded as a Cai Niao!By writing the article, the writer tries to.
| A．explain some Internet language |
| B．suggest common Internet language |
| C．laugh at the Beijing father |
| D．draw our attention to Internet language |
What does the writer think about the term “PK”?
| A．Fathers can’t possibly know it. |
| B．The daughter should understand it. |
| C．Online game players may know it. |
| D．“Super Girl” shouldn’t have used it. |
The examples of the Beijing father and the Tianjin teacher are used to show that Internet jargons.
| A．are used not only online |
| B．can be understood very well |
| C．are welcomed by all the people |
| D．cause trouble to our mother tongue |
What would be the best title for the passage?

It’s such a happy-looking library, painted yellow, decorated with palm-tree stickers and sheltered from the Florida sun by its own roof. About the size of a microwave oven, it’s pedestrian-friendly, too, waiting for book lovers next to a sidewalk in Palm Beach country Estates, along the northern boundary of Palm Beach Gardens.
It’s a library built with love.
A year ago, shortly after Janey Henriksen saw a Brian Williams report about the Little Free Library organization, a Wisconsin-based nonprofit that aims to promote literacy and build a sense of community in a neighborhood by making books freely available, she announced to her family of four, “That’s what we’re going to do for our spring break!”
Son Austin, now a 10th-grader, didn’t see the point of building a library that resembles (像)a mailbox. But Janey insisted, and husband Peter unwillingly got to work. The 51-year-old owner of a ship supply company modified a small wooden house that he’d built years earlier for daughter Abbie’s toy horses, and made a door of glass.
After adding the library’s final touches (装点), the family hung a signboard on the front, instructing users to “take a book, return a book,” and making the Henriksen library, now one of several hundred like it nationwide and among more than 2,500 in the world, the only Little Free Library in Palm Beach County.
They stocked（贮存） it with 20 or so books they’d already read, a mix of science fiction, reference titles, novels and kids’ favorites. “I told them, keep in mind that you might not see it again,” said Janey, a stay-at-home mom.
Since then, the collection keeps replenishing (补充) itself, thanks to ongoing donations from borrowers. The library now gets an average of five visits a day.
The project’s best payoff, says Peter, are the thank-you notes left behind. “We had no idea in the beginning that it would be so popular.” (317 words) The library was built __________.
| A．by a ship supply company | B．on the basis of toy horses |
| C．like a mailbox | D．with glass |
What can we infer about the signboard?
| A．It was made by a user of the library. |
| B．It marked a final touch to the library. |
| C．It aimed at making the library last long. |
| D．It indicated the library was a family property. |
The passage tells us that the users __________.
| A．donate (捐)books to the library |
| B．get paid to collect books for the library |
| C．receive thank-you notes for using the library |
| D．visit the library over 5 times on average daily |
