Have you seen Avatar?It’s a popular movie this year. It is three-dimensional(3D), so you may have to wear a special pair of glasses to see it. The 3D glasses make the images(圖像) from the movie look like they are coming straight at you.
More and more 3D movies are coming to theaters. 3D TV sets have been produced in Japan now. Three-dimensional technology can make TV and movies more exciting. But people with eye problems may get headaches if they spend too much time watching 3D movies.
When we look at an object(物體), each eye sees it at a different angle(角度). Our eyes send the two images to our brain(大腦), and the brain puts them together. That’s how we see depth(深度). So when we watch a 3D movie, one film projector(投影機(jī)) projects a left eye image and the other projects a right eye image. 3D glasses allow us to see a different image in each eye.
There are a lot of people walking around with very less serious eye problems. Under normal situations, the brain can adjust to their eyes so they can see things normally.
But when they are watching a 3D movie, the images projected to their eyes can’t be put together by their brain. So the brain needs to work harder at reading the images. That makes it easier for these people to get headaches.
Dr John Hagan, an eye doctor in Kansas City, said some people who do not see depth normally cannot see in 3D at all.
小題1:When people want to watch a three-dimensional movie, they need          .
A. a ticket                  B. a pair of 3D glasses             C. an earphone
小題2:Three-dimensional technology uses         film projector(s) to project one movie at the same time.
A. one                     B. two                         C. three
小題3:According to the passage, if we look at an object by only one eye, we can’t judge the       excatly.
A. image                   B. angle                         C. depth
小題4:Which statement is TRUE according to the passage?
A. In the near future, people can enjoy 3D movie by watching TV at home.
B. Whenever you wear a 3D glasses, you can see objects more clearly.
C. People who have something wrong with their brain can’t read the images of 3D movie.
小題5:The main idea of this passage is            .
A. how to use 3D glasses to watch a 3D movie.    
B. 3D glasses make the movie seem alive
C. not everybody can enjoy 3D movies.

C
Why are you study habits different from those of your friends? Why do you seem to learn faster in some classes while more slowly in others? One reason you may not know is that people have different types. Scientists say there are three different learning types: Visual(視覺型),Auditory(聽覺型),and Kinesthetic (動(dòng)覺型)。
Visual learners learn best by seeing. If you seem to easily remember information from pictures, graphs(圖表),and videos, you are probably a visual learner. You’re not good at copying down what the teacher says in class. Never mind. You can draw graphs or pictures instead, if you find that works better for you.
Auditory learners learn best by hearing. If you seem to easily remember things by hearing them, then you are probably an auditory learner. You must listen carefully while the teacher is speaking because it’s the easiest way for you to learn . Sometimes you may find that taking notes tops you from listening carefully. After class, you can write down what you remember or borrow your friend’s notes to copy.
Kinesthetic learners learn best by doing. If you seem to learn best by working with your hands, you are probably a kinesthetic learner. Taking notes by writing can make you pay close attention to information as you receive it. Of course, you can learn best by making full use of labs or other class activities.
Hope you learn better by knowing what your personal learning type is.
小題1:There are____________ different learning types according to the passage.
A.twoB.threeC.fourD.five
小題2:Jude can remember the words of a song quickly by listening to it once or twice. She might be a /an ____________ according to the passage.
A.a(chǎn)uditory learnerB.visual learner
C.strange leanerD.usual learner
小題3:Kinesthetic learners learn best by  ____________
A.Remembering information from videosB.listening teachers in class
C.drawing graphs or picturesD.doing things with their hands
小題4:The best title of this passage may be “____________”
A.Study HabitsB.Ways to study

Have you ever rubbed your hands together when they get cold? Why do we do that? We do that for friction. Friction happens when two things that aren’t very smooth (光滑的) rub together to make heat energy. The faster you rub two things together, the more friction you can make. Let’s discover friction!

WHAT YOU’LL NEED:
★Soap                ★Water           ★Your hands
WHAT TO DO:
★Make sure your hands are dry.
★Rub your hands together until you feel the heat of your hands.
★Now, use soap and water to get your hands very slippery (滑的).
★Try to make friction happen while your hands are slippery.
★Please write down what has happened.
LET’S TALK!
Friction is an energy that happens when two things rub together. When friction happens, it makes heat! When your hands are slippery, they won’t make very much friction and your hands won’t get so hot.
DID YOU KNOW?
★Friction happens when you stop your fast running bike.
★Ancient people made fires by rubbing two pieces of wood together. Friction happened though they didn’t know it. ___  __?         Friction is everywhere. Have you ever noticed situations where friction is happening? If not, ask your parents to take you out in a car. If it is not hot, touch the tires (輪胎) of the car before and after a short drive to see how much warmer they get from friction.
小題1:You’d better make your hands ______ to get heat when you rub them.
A. slippery                 B. dry                  C. wet

閱讀下面短文,根據(jù)所讀內(nèi)容,在文章后小題的空格里填入一個(gè)最恰當(dāng)?shù)膯卧~。
Blood donation, also called blood banking, is a wonderful thing to do. It is an easy and direct way of making a contribution to social work and having a big effect on the community. It helps to save lives and helps those who are in need of blood because of bad conditions or the heavy loss of blood during operations or in accidents.

You are able to give or donate blood every three or four months. The doctors say it is not bad for your health. It is such a beautiful way of making a huge difference to someone’s life and you can always be proud of it if you make a valuable contribution to society. Blood donation is not a big problem, but you need to keep a few points in mind.
Before donating blood, make sure that the ferrum(鐵) level in your body is high enough and for that you should take a healthy diet. Do not go for blood donation with an empty stomach. You should follow the correct process so that everything goes well. After having a balanced diet you will feel strong and comfortable to donate blood. You will not feel weak at the same time.
For required hemoglobin(血紅蛋白) in your body, drink lots of juice and other drinks. Fruit juice, such as apple juice is very good for increasing the blood level in your body.
For a good blood flow(血流) in your body, drink at least 6-7 glasses of water every day. Completely avoid taking alcohol or caffeine a day before and after giving blood. Do not smoke cigarettes(煙) half an hour before giving blood.
When you are going for blood donation, be relaxed, which helps keep the right blood pressure(血壓). During the blood donation activity, you can breathe deeply and try to calm yourself down. Don’t take part in some other activities.
When you donate blood, you are making the effort to save someone’s life. Blood donation is a very simple and fast process, but you need to take care of yourself after donating blood. Proper care helps to reduce side effects. The following are a few tips that will help you out.
Take a rest for 15 minutes after completion of the donation. It helps you to feel relaxed and energetic.
Eat something and drink juice before leaving the blood donation center. Make sure that you have meals after donating blood. Smoking should be prevented for one hour after the process. Don’t join in some activities at once, for example, driving.
Finally, be proud of yourself because you have done a great thing in helping to save someone’s life. Blood donation is a very important activity.

You change the channels for the fourth time and realize that once again there’s nothing on television that gets your attention. Not a problem! Throw on some running shoes and comfortable clothes and go for a run.
One of the coolest things about the sport of running is that you don’t need expensive equipment(裝備). All you need is a good pair of running shoes and a safe environment. But just because you don’t need much equipment don’t be fooled into thinking the sport of running is easy. No one wakes up and decides to run a marathon without training.
Running makes your heart, lungs, and muscles stronger. It makes you know more about your body. Running also gives you energy by increasing your oxygen(氧氣) intake, so you don’t get sick easily. It can even help you keep your mind on school work because exercise helps you to think more clearly.
How do you take part in the sport if you don’t know much about it? Most schools offer cross-country and track programs, but there are also running clubs open to all ages. A simple Internet search can help you find some in your area. The programs show you how running can offer competition or just be for fun. They also teach runners to set realistic goals and take care of their bodies.
Runners have great respect for each other because they know how difficult the sport can be. If you go to a race, you’ll see people cheering for all the runners, from the first place finisher to the last place finisher. Running isn’t always about how fast you are or how far you’re going. It’s about getting out there and doing it. Taking part is more important than competition, and effort is recognized over gift.
If you’re looking for more than just a sport, running may be the perfect choice for you.
小題1:Which of the following is true?
A.Running helps you win a marathon.
B.Running helps you improve your study.
C.Running helps you think more about yourself.
D.Running helps you set realistic goals in your life.
小題2:What is the most important for runners in a race?
A.Having fun.B.Receiving respect.
C.Trying their best.D.Winning the competition.
小題3:What is probably the best title for this passage?
A.Running and Runners
B.Running: Easy or Difficult
C.Running and Watching TV

Most of the things around you will be replaced or thrown away someday. Where will they go when they are thrown out? What kinds of waste will they create, and how will it affect the environment
Most of our crash goes to places called landfills. A LANDFILL is a low area of land that is filled with garbage(垃圾).Most modern landfills are lined with a cover of plastic to keep dangerous liquids(液體)from polluting earth and ground water supply. The problem is that more than half of the states in this country are running out of places to landfill their garbage. Because of the unhealthy materials, landfills do not make good neighbors,and people don’t want to live near them. Many landfills are set in poor neighborhoods.
The Fresh Kills landfill on Staten Island, New York, was the largest garbage landfill in the world. For years, people who live nearby complained about air and water pollution caused by the enormous pile of trash. They say that the smoke have made people sick. The landfill closed in
April 2001.Now can a harmful waste—material that can pollute air, land, and water –be disposed of in a safe way.
Another way to get rid of trash is to burn it. Trash is burned in an incinerator._ Because incinerators in operation can get rid of almost all of the trash, some communities would rather use incinerators than landfills. There is a problem, though. Leftover ash and smoke from burning trash may have dangerous chemicals, and even make it hard for some people to breathe. They can harm plants, animals, and people.
You can help reduce(減少)waste by reusing bottles, batteries, and paper. You can also recycle newspaper, glass, and plastics t to provide materials for making other products.
From recycled materials, many things are made. For example, from recycled paper we can get newspapers, boxes and so on. From recycled plastic we can get soda bottles, tables, and backpacks.
小題1:Why don’t landfills make good neighbors?
A.Because there are unhealthy materials in them.
B.Because people prefer to live in the city center.
C.Because landfills are not big enough for trash.
D.Because most states are running out of places.
小題2:What does the underlined word “incinerator”_probably mean?
A.An area to collect trash.B.A machine to burn trash
C.A method that is used to burn trash.D.A station that is run by selling trash.
小題3:What is probably the best title for the passage?
A.How Is Trash Burned?B.What Can Be Reused.
C.Why Is Waste Dangerous?D.Where Does Garbage Go?
