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(設備). 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(沖洗) 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.

The human body is a living machine, and, like all machines, it needs “fuel” to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy?
The energy value of food is usually measured in calories(卡). A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different, as the picture shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on.
The energy in food is in the form of three kinds of chemical materials—carbohydrate(碳水化合物), protein(蛋白質) and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show.
(P= protein      C= carbohydrate    F=fat)
小題1:How many calories are needed to raise the temperature of 5kg of water from 35℃ to 90℃?
A.55.B.175.C.325.D.275.
小題2:Which of the following contains the most amount of calories?
A.Milk.B.RiceC.Peanuts.D.Milk or peanuts.
小題3:Who needs the most amount of calories each day?
A.A woman.B.An office worker.C.A farmer.D.A boy aged 16.
小題4:Which of following is True?  
A.You need more calories for swimming than for mountain climbing.
B.A child aged 8 needs the same amount of calories every day as a man over 70 does.
C.A woman feeding baby needs over 4 times the amount of calories that a baby does.
D.Everyone needs the same amount of calories per day.
小題5:This passage mainly tells us ______.
A.all the energy is in food
B.the human body needs energy

Many people catch a cold in the spring time and / or fall.  It makes us wonder .if scientists can send a man to the moon, why they can't find a cure for the common cold. The answer is easy.

Blood rushes to your nose and brings congestion(充血)with it .You feel terrible because you can't breathe well, but your body is actually "eating" the virus.

Last weekend, twenty thousand people gathered in the state of Georgia to watch students from twenty-eight countries compete with robots they built. More than ten thousand students and more than five hundred robots took part in the competition.

Almost one thousand and seven hundred high school teams entered a level of competition called LUNACY. The competitors came from eleven countries, including the United States. In January, the organization sent the same supplies for robots to each team. The teams had six weeks to build robots that could compete in the LUNACY game. The playing area had six robots, three on each team. Each robot had a trailer(拖車) connected to it. The robots had to pick up large balls and throw them into the trailers of opposing robots. The robots were moving on a surface where they could slide(滑行). A team from California won the competition.
A second competition involved building a robot that could travel on uneven(不平坦的) surfaces, move objects with unusual shapes and withstand(承受) physical stress.

Answer the questions(根據短文內容回答下列問題)
Your Nose is Busy and Important
Your nose has many important jobs, and is always busy.
Smelling
Smelling helps you gather information about the world around you. A good scent (氣體),like flowers, brings you pleasure. A bad scent, like smoke or sour milk, warns you of danger. Most things around you release scent particles (微粒) into the air. These invisible chemicals enter the nose when you breathe. Nerves in the nose send information to the brain to identify a smell. You are able to recognize thousands of smells.
Breathing
Most of the air you breathe enters through your nose. The nose uses hair and mucus (粘液) to clean dust and germs (細菌) out of the air. The air that enters your nose contains oxygen. Your body uses oxygen to unlock the energy in the food you eat.  Even when you sleep, your body needs energy to keep your heart beating and your brain working.
Tasting
Your nose helps you enjoy food. Flavor is a mixture of taste and smell. The smell of the food helps you identify what you are eating. The sense of smell contributes more to (貢獻) food flavor than the sense of taste .When you are sick and have a stuffy nose, your food doesn’t taste as good because without smell, food loses most of its flavor.
Smell memory
Smells can bring back memories. Your brain uses a process to create a picture in your mind from the odors(氣味)you smell. Smells can affect your feelings because the part of the brain that helps you identify smells is close to the area that affects your emotions, mood and memory. More smell memories are collected as you get older.
Your nose has many important jobs, and is more than just a smeller!
小題1:How many important jobs does a nose do according to the passage? What are they?
小題2:Smelling helps you recognize thousands of smells, doesn’t it?
小題3:What does the nose use to clean dust and germs out of air?
小題4:What happens to your food if you are sick and have a stuffy nose?
小題5:How do smells bring back memories?
小題6:What do you think of your nose? Why do you think so?
