People are busy working every day, so they do not have enough time to do exercises. As a result, many people become too fat or too thin. To keep our bodies healthy, we have to do exercises every day.
There are many kinds of exercises. Bending (弯腰) and stretching (伸展) helps us move easily. Before we play ball games or swim, it is better for us to do bending and stretching exercises first. This kind of exercise is sometimes called warm-up exercise. Running is also a good exercise. If we cannot run fast, we can Jog. Jogging means running slowly. Again, before we run or jog, we must do warm-up exercises. Also, we should not run or jog in busy streets. The air there is often dirty. Some people like weight lifting (举重)because it can make their bodies strong. Also, we need to do some warm-up exercises before weight lifting.

Photography is about taking photographs. In 1826, a Frenchman named Niepce needed pictures for his business. But he was not a good artist. So he invented a very simple camera. He put it in a window of his house and took a picture of his garden. That was the first photograph.
The next important date in the history of photograph was 1837. That year, Daguerre, another Frenchman, took a picture of his studio. He used a new kind of camera and a different process. In his pictures, you could see everything very clearly, even the smallest details. This kind of photograph was called a daguerreotype.
Soon, other people began to use Daguerre’s process. Travelers brought back daguerreotypes from all around the world. People photographed famous buildings, cities and mountains.
In about 1840, the process was improved. The photographers could take pictures of people and moving things. The process was not simple. The photographers had to carry lots of films and processing equipment(设备). But this did not stop the photographers, especially in the United States.
Mathew Brady was a well-known American photographer. He took many pictures of famous people. The pictures were unusual because they were very life-like and full of personality. Brady was also the first person to take pictures of war. His 1862 Civil War pictures showed dead soldiers and destroyed cities. They made the war seem more real and more terrible.
In the 1880s, new inventions began to change photograph. Photographers could buy films readymade in rolls(卷). So they did not have to make the film themselves. Also, they did not have to process(冲洗) the film at once. They could bring it back to their studios and develop it later. They did not have to carry lots of equipment. And finally, the invention of the small hand-held camera made photography less expensive.
Photography is also a form of art. Some photographs were not just copies of the real world. They showed ideas and feelings, like other art forms.
Title: The    1  of Photography
Photography doesn’t only mean taking photographs; it is also a form of art. Photographs showed not only the real world, but also the ideas and feelings.

We use the Internet for many things: business, shopping, writing letters, talking to people, finding information, and so on. In recent years, a new kind of English has grown on the Internet. There’s no real word for it yet, so we’ll call it e-talk. People don’t like typing too much. To save time, they turn phrases (短语) into a few letters called acronyms(首字母缩略词). Acronyms are often used in chat rooms.
Some of them are:
BTW(by the way)     BRB (be right back)
LOL (laughing out loud) IMO (in my opinion)
People also use many abbreviations. They are shortened forms of words. Some common abbreviations are:
info (information)    puter (computer)    pic (picture)      sec (second)
We usually don’t see people when we communicate on the Net, so people have new ways to show feelings. Most people use their keyboards to draw “feeling”, such as:
: ) (happy)     :-( (sad) ;    : P (joking)   : O (surprised)
These days, many forums have picture feelings. For example:
happy          sad         angry        cool
There are even whole new words, like ‘newbie’ (someone who is new on a chat board or forum). When you write something bad about someone else, it’s called ‘flaming’ the person.
It takes time to get used to e-talk. Also, different groups in the Net have their own special ways of communicating. Newbies sometimes have to ask other people what they mean. As the Internet grows, e-talk will continue to grow and change.
小题1: Why do people type acronyms?
A.To show their feelings.
B.To make jokes.
C.Because people can type them quickly.
D.In this way, newbies won’t understand them.
小题2:What does “My puter is not working well. :-( ” mean?
A.The person is happy about getting a new computer.
B.The person has to go away from their computer.
C.The person is angry at somebody.
D.The person is sad that his computer is having problems.
小题3:If someone is angry, what may he type?
A.B.C.LOLD.BRB
小题4:E-talk will probably_________.
A.keep changing
B.stay the same
C.be used by people on the telephone
D.be easy for newbies to understand
小题5:People can do the following through the Internet except _________.

We talk every day. When we have good news, we like to share it with our good friends and when something terrible happens, we tell it to others soon. But can you imagine that a tree can talk and share news too ? Of course, no tree moves lips and says words just as people do. Strange as it may sound, though, some trees do manage to communicate with each other.
Willow (柳树) trees are the best-known of these trees. When insects begin nibbling (叮咬) a willow tree, the tree sends out a special smell at once. This smell tells the other willows that harmful insects are coming near. All of them quickly make a chemical (化学物质) in their leaves. This chemical is bad to the insects. The insects do not like it and they fly away soon. In this way, the willow trees protect themselves from the insects.
The next time when you take a walk in the woods, maybe the trees are “talking” to each other quietly. And when someone says that trees cannot “talk”, please tell them that even trees give messages to each other, too.
小题1:Willow trees send messages with_____________.
A.wordsB.movementsC.smellsD.sounds
小题2:The underlined word “lips” in the first paragraph means _____________.
A.树干B.嘴唇C.枝条D.手势
小题3:The passage tells us that some of the trees can _____________.
A.speak just as people doB.tell stories to others
C.communicate with each otherD.kill insects in the woods
小题4:According to the passage, the right order of the following is _____________.
a.  The willow tree gives out a smell.
b.  The willow trees make a chemical in their leaves.
c.  Insects fly away because of the chemical.
d.  Insects begin nibbling a willow tree.

There are about 80.000.000 mines under the ground in more than 60 countries. It is difficult and dangerous to clear these mines.About 50 people including many children were killed or hurt each day.In 2003,APOPO,a Duch research company that trains the animals,came up with the idea of using rats to search for the mines.
The animal trainers found that a kind of rats from Africa were clever and had a sharp sense of smell.The rats were about 75 cm long and weighted about 1.35 kg.light enough to run across a minefield without setting off the mines.
In January 2004,the  APOPO startec this preject.First ,the trainers let the 4-week-old baby rats get familier with humans. A few weeks later,the rats were no longer afraid of people and the things around them.Then they were trained to connect a click sound with food.After the rats had learned that ,the trainers then taught them to tell the different between the smell of mines and other smells.When the rats could do it,the click was sounded and they were given a bit of bananas.The method was called clicker training.“The training isn’t easy.”said the trainer Adulish Mebomvu.“You have to be patient.Sometimes I get angry,but then again.I tell myself these are animals.”
After nine months’ training,the rats were taken to 4 minefield. They ran across the minefield ,stopped, sat and searched the ground to tell the deminers that they smelt out a mine. Then the mine was cleared.It had taken two deminers a day to clear a 200 m2 minefield. But with the help of two rats they could finish it in two hours.
The rats and the deminers saved thousands of lives.“The rats did this job much better than we expected.So far they have helpde to make almost 2.000.000 m2 of land safe.They are heroes.”said Bart Woetjcds.the head of the APOPO.

Three kids have been learning chemistry for only a few months. But they have already begun to challenge (挑战) a world famous scientist!
Li Weichi, Huang Runling, and Xiao Yan are from Zhongshan Huaqiao Middle School in Guangdong. They have just found a red cabbage that could be a new kind of acid-base indicator (酸碱指示剂). They want it to take the place of litmus (石蕊) paper.
"We’ve learnt to think of and ask questions about life by ourselves," said Li, "We work well with each other."
British scientist Robert Boyle discovered the use of litmus paper over 300 years ago. Now it is used widely in experiments all over the world.
But when the kids did some experiments in class last winter, they saw that the litmus paper didn’t turn very blue with base matter. It’s hard to get a clear result.
Will there be a better indicator than litmus paper? The three kids decided to try and find out!
How? They went to collect over 40 plants in parks, gardens and markets. Then they ground (研磨) leaves, flowers and stems (茎) to get the pigments (色素) from them.
The kids mixed pigments with acid and base. They spent months watching carefully to see which paper showed the best colour change. They decided it was the litmus paper!
"It’s our first scientific journey, Huang said, "But it makes me want to try harder."
小题1: Whom did the three kids want to challenge?
A.Their chemistry teacher.B.Their headmaster.
C.Robert BoyleD.Thomas Edison
小题2: From the text, a red cabbage is a kind of ____.
A.plantB.animalC.paperD.liquid
小题3:What is widely used as the acid-base indicator now?
A.red cabbageB.litmus paper
C.any plantD.any flower
小题4:The story mainly tells us ____.
A.how to make litmus paperB.about the three kids’ spirit
C.scientists were wrongD.the kids are heroes
